2. Less flue gas emissions

The calcium hydroxide production line has less flue gas emissions, is a very energy-saving production equipment, and complies with the proposed green environmental protection standard.

3. High degree of mechanization

The calcium hydroxide equipment has a high degree of mechanization, and many process computers can be controlled, reducing the disadvantages of manual control. Take labor as an example, skilled workers can produce standard products, but the products produced by new workers are not standard enough, which leads to product inconsistency. The computer-controlled production line produces standardized products.

4. High production efficiency

The efficiency of traditional artificial production is low. Each person does not exceed 1 ton of finished calcium hydroxide during the day. The production capacity cannot meet the large demand for calcium hydroxide in various industries such as power plant desulfurization, fine chemical industry, pharmaceutical food, petroleum, and paper making. The single-machine output of calcium hydroxide production line ranges from 3T/h to 20T/h, and the product fineness ranges from 200 mesh to 600 mesh. Different schemes can be completed according to user requirements and the product quality meets industry requirements.

5. Excellent inspection system

(1) Rigid inspection by electronic means, and inspection personnel sampling unit time, can ensure the stability of product quality and prevent quality problems caused by deviations in raw material production.

(2) Rigid assessment is carried out by electronic means, and equipment maintenance personnel conduct inspections on the operation cycle of each part, so as to find problems in time and solve them in time to avoid equipment running with faults.

(3) Electronic rigid inspection method, each running part is lubricated and circulated to avoid oil-free operation and accidental wear.

Working principle of calcium hydroxide production line

The quicklime is crushed to about 10-40mm by the crusher, and then sent to the crushed calcium oxide storage tank through the bucket elevator. Under the slow and low-speed stirring of the stirring rod (basically no wear), the preliminary digestion and decomposition is completed by chemical means (it can be divided into single, double and triple shafts according to different output), and then enters the secondary and tertiary slaked lime chemical digesters (according to the output Different can be divided into single, double and triple axis) to complete the digestion process.

After the digested lime is naturally decomposed into qualified meshes by chemical means, it is sent to the bucket elevator by the semi-finished product screw conveyor, and then sent to the mesh classifier by the bucket elevator (the mesh number can be adjusted arbitrarily). Slaked lime and remove impurities. The slaked lime is sent to the bucket elevator by the finished product conveyor and then unloaded into the finished product calcium hydroxide silo, and then sub-packaged according to the needs of the user (can be in a tanker or in a bag).

The above is the answer to the question of what are the advantages of the calcium hydroxide production line. After the above introduction, it can be seen that the calcium hydroxide production line has the advantages of producing diversified products, less exhaust gas, high degree of mechanization, high production efficiency, and excellent inspection system, etc. Advantage.

As a large-scale equipment, calcium hydroxide equipment needs to be properly kept when not in use, otherwise it will only cause wear and tear of the equipment. To keep equipment and accessories safe from corrosion, loss and damage. So, how to storage calcium hydroxide equipment?

1. According to the specific situation of the construction progress, when the calcium hydroxide equipment is not in use, the project should maintain and transform the deactivated equipment, and require the technical conditions to meet the specified secondary standards. Within one month after the completion of the transformation, the company shall notify the Department of Machinery, Materials and Equipment in writing for acceptance.

After the acceptance is passed, the calcium hydroxide equipment will stop charging the three fees for the project next month, otherwise the decoration will continue until the acceptance is passed. During the renovation period, the Mechanical Materials Department will continue to collect three charges.

2. When the calcium hydroxide equipment and auxiliary accessories are out of use, they should be stored in a dry and ventilated place for easy drainage and observation to avoid disassembly, loss or wrong installation.

3. The storage place should be equipped with sufficient fire-fighting equipment, and flammable materials should not be stored near the storage place to prevent fire.

4. The calcium hydroxide equipment should be cleaned before storage, and the water used to remove dirt, dust and other dirt should be drained. The lubricating part should be oiled, and the outer processing surface should be oiled. In addition to oiling, machined surfaces should be wrapped and protected. The nameplate on the machine should be wiped clean and the writing is clear. The water should drain completely. The lubricating part should be oiled, and the outer processing surface should be oiled. In addition to oiling, machined surfaces should be wrapped and protected. The nameplate on the machine should be wiped clean and the writing is clear.

5. Pipes leading to the interior, such as water inlet and outlet, refueling (water) port, exhaust hole, inspection hole, etc. It should be wrapped and pipe fittings, especially upward facing pipes, should be capped and carefully plugged to prevent foreign matter from entering the cylinder.

6. The internal combustion engine should be started once a month. If it fails to start, it should be moved and rotated to lubricate the inside of the calcium hydroxide equipment and prevent rust.

Therefore, when keeping and storing calcium hydroxide equipment, it is necessary to pay attention to the above requirements and regulations, and keep it in the correct way to ensure that the equipment can be kept in good condition during long-term storage and shutdown.

The production process of calcium hydroxide processing equipment is to crush qualified block calcium oxide through a jaw crusher to a particle size of about 40mm, and send it to the calcium hydroxide storage tank through a bucket elevator, and then quantitatively transport it into the first-level digester , carry out the preliminary reaction, and then enter the secondary or tertiary digester for reaction, and no smoke and dust will be emitted during the reaction.

After the completion of the digestion reaction, the calcium hydroxide product enters the powder concentrator to complete the classification of product impurities and fineness. After completing the classification and optimization, the finished product enters the finished product storage tank through the conveyor and the elevator for packaging.

No matter what you buy, a clear purchase purpose is a very important beginning. Because only when you choose a product that suits you can you make the later use more smooth, whether it is a normal product or a large-scale production equipment, it is very important for the purchase, so choose calcium hydroxide production equipment, what do you mainly look at?

Purchase calcium hydroxide production equipment

1. In fact, for large-scale production equipment such as calcium hydroxide equipment, we should not be greedy for cheap, because after all, you get what you pay for. Of course, you don’t have to choose the so-called top equipment, because only the equipment that suits you is a good equipment. , When buying calcium hydroxide equipment, you must do a good job on-site inspection and choose according to your actual needs.

2. For the internal structure of calcium hydroxide equipment, it is very complicated, so we must understand its internal structure, plus calcium hydroxide equipment is a production type equipment, for the production of calcium hydroxide It is also very important. Only when the internal structure is understood can the calcium hydroxide production be better. If it is necessary to sign an agreement with the calcium hydroxide equipment manufacturer when purchasing.

3. Look at the effortless operation of the oil pump motor. Because when the oil pump motor is running hard, it will cause the motor to be burned, and it will not be good if it delays our use. The reason for this failure is usually that the pressure adjustment of the total pressure regulator of the calcium hydroxide equipment is too large. The total pressure regulating valve should be reduced gradually until the motor runs normally. Therefore, after buying the equipment, we also need to adjust and check the operating status of the machine in time.

4. Check whether the vibrating force of the vibrator will be insufficient. After all, when the vibrating force of the vibrator is insufficient, the calcium hydroxide cycle will be long or the calcium hydroxide will be loose, and the pressure of the lower mold will be too large. The pressure suppresses the vibrating of the vibrator, so the pressure of the independent pressure regulating valve corresponding to the upper oil pipe of the lower die cylinder should be reduced. This equipment is not recommended for purchase.

5. To see if the calcium hydroxide production equipment meets the deep processing standard, the whiteness needs to be well controlled, and the effective calcium oxide is produced with more than 90% lime. This requires matching high-efficiency, high-quality, energy-saving and consumption-reducing production line equipment to further meet production needs.

The above is a specific analysis of the precautions for purchasing calcium hydroxide production equipment. It is hoped that some users can choose the appropriate model when purchasing. Only the appropriate model can bring very large effects and production benefits.

The hydrated lime (slaked lime) production line equipment consists of: raw material silo, jaw crusher, bucket elevator, feeding silo, screw conveyor, ashing machine, primary digester, secondary digester, pulse dust collector, screw conveyor, It is composed of bucket elevator, powder separator and powder collector. The main production processes are generally divided into two types: dry process and wet process. As a professional slaked lime equipment manufacturer, Cafeng will give you the following detailed introduction on the characteristics of the dry process of slaked lime equipment. Let’s take a look!

Dry process characteristics of hydrated lime production line:

1. It can control the digestion reaction time of quicklime in the digester. Through PLC centralized control and multiple adjustment methods, the lime digestion process can be effectively controlled. The digester can reach 8-15 minutes, so that the quicklime can be completely digested.

2. The digester has good heat preservation performance. The unique design enables a large amount of heat generated during the reaction of quicklime (CaO) to pass through the thermal conversion system, so that the heat in the reaction is fully utilized, which helps to increase the temperature of the internal quicklime digestion material, and improve the digestibility and reaction speed.

3. The feeding process is controlled. The equipment adopts a screw propeller, which can quantitatively transport the material into the first-level digestion chamber, which can prevent the quicklime and water from generating a large amount of hot steam and dust countercurrently entering the spiral feeding scale, which affects the accuracy of the sensing signal .

4. Optimize water distribution and digestion. Through the hierarchical scientific water distribution method, the best water distribution method, the best water distribution ratio and the water distribution time are selected, so that the quicklime can be fully digested.

5. To solve the smoke and dust pollution, the dry digester can effectively treat and purify the hot steam and dust generated in the process of quicklime digestion, ensuring that the worker’s operating environment is free of dust pollution, and the steam outlet concentration can reach no more than 20 per cubic meter of dust content. Milligrams, in line with national emission standards.

Recommendations for selection of hydrated lime production line equipment manufacturers:

When selecting a slaked lime production line, the first thing to consider is strong professionalism, high technical level, and skilled installation. Of course, it is best to go to the slaked lime production line manufacturer to conduct on-site inspections to comprehensively evaluate product quality and actual production conditions.

Whether the product design plan is comprehensive, whether the equipment accessories are matched or not, whether the manufacturer’s qualifications, after-sales service are complete, and whether the personnel training is in place are all the guarantees that determine the smooth and efficient production of the company after purchase.
