Water Mist Dust Collector for Calcium Hydroxide Production line – Ultimate Solution for Pollution-Free Processing
During the digestion process, lime will produce a large amount of hot water vapor, which will carry a certain amount of calcium hydroxide powder. After the pulse dust collector removes dust once, it enters the preheated water mist dust collector to collect the powder mist twice or three times, and then becomes clean hot water vapor, which is discharged into the atmosphere through the pipeline.
The calcium hydroxide water collected by the preheated water mist dust collector in the water storage tank has a water temperature of 60-80 degrees Celsius. Some sediment is circulated by the general sewage pump into the first-level pre-digestion to promote the chemical reaction of quicklime, so as to shorten the digestion time, improve the quality of calcium hydroxide and discharge no sewage.
Production background
In the process of converting calcium oxide (CaO) into calcium hydroxide (Ca(OH)₂), a large amount of hot steam is generated, and a certain amount of calcium hydroxide dust is entrained in the gas. If it is naturally discharged into the air, white pollution will inevitably occur, which will seriously affect the surrounding environment of the factory area (plant production area). The use of water mist dust collector will completely solve the source of white pollution
Capacity: >15～18t/h
Scenario: In the process of converting calcium oxide (CaO) into calcium hydroxide (Ca(OH)₂) by adding natural water (H₂O), a large amount of hot steam is generated, and a certain amount of calcium hydroxide dust is entrained in the gas. If it is naturally discharged into the air, it will inevitably cause white pollution, which will seriously affect the surrounding environment of the factory (factory production area). Using the GK-PSC series water mist dust collector will completely solve the source of white pollution.
Functional characteristics
During the digestion process, lime will produce a large amount of hot water vapor and carry a certain amount of calcium hydroxide powder. After the pulse dust collector is used for dust removal, it enters the preheated water mist dust collector for two or three times to collect the powder mist and become clean hot water vapor, which is discharged into the atmosphere through the pipeline.

High cost performance
When calcium oxide (quicklime) is added with water and stirred in the digester box, a large amount of hot steam is continuously generated. Spray nozzles and spray nozzles of different sizes are installed in the discharge pipe. Under the action of the fan and dust removal water pump, a water curtain area of a certain width is formed. The hot steam with calcium hydroxide dust is filtered through the water curtain area and becomes clean and environmentally friendly water vapor, which is discharged into the atmosphere through the pipeline.
Summary of technical features
The new design is compact and occupies a small area (30000×50000mm), which is suitable for space-constrained factory layout.
Quality-friendly
Pulse + water mist dual dust removal reduces the stringent requirements for bags (alkali resistance/waterproof/temperature resistance) and reduces the risk of damage.
Maintenance-friendly
Water curtain protection + circulation/clean water alternating cleaning prevents calcification and adhesion, extends equipment life, and reduces the frequency of downtime maintenance.
Efficient dust removal
Three-stage dust removal (pulse + water mist secondary/tertiary filtration), dust removal rate> 99%, emission meets standards, and eliminates “white smoke”.
