Product Description
The working principle of the boiler pulse bag filter:
The flue gas enters the venturi through the flue and is evenly sprayed by the water at the entrance of the throat. Due to the high speed movement of the flue gas, the sprayed water is melted into a fine mist of wet smoke in the flue gas. The ash and water droplets collide and condense, especially the dust with a small diameter can be dissolved by water mist. To achieve _ secondary dust removal and desulfurization, these are fully prepared for the separation of ash, and then enter the cylinder, the flue gas that rapidly reduces the temperature continues to impact the lime water in the pool, and the dust and SO in the flue gas form _ secondary desulfurization process The water splash caused by the flue gas, the water mist and the washed flue gas are lifted by the fan at the same time, the gas and water are lifted at the same time, so that the flue gas and lime water fully react, and then the gas and water are separated by the impeller dehydrator, and the water passes through the drain pipe It flows into the pool and completes the third dust removal and desulfurization of the flue gas. The purified gas is discharged into the atmosphere through the fan.
Scope of use of boiler pulse bag dust collector:
Boiler bag dust collector is suitable for large, medium and small vertical boilers and horizontal chain furnace boilers, kilns, brick factory tunnel kiln flue gas desulfurization and dedusting, brick gangue flue gas dedusting and desulfurization, also suitable for ferrosilicon furnaces , Silicon calcium furnace and other high smoke and dust concentration, sawdust fuel boiler, straw fuel boiler, wood fuel boiler, heavy oil fuel boiler flue gas, waste plastic fuel boiler flue gas and other difficult to treat flue gas. Boiler pulse bag filter is widely used in boilers and industrial industries to achieve the dust removal and purification of boiler flue gas.
Are users still worried about choosing the model of boiler pulse bag filter? Ginza Environmental Protection can help you solve the selection problem.
(1) The main technical parameters of the dust collector selection are air volume, gas temperature, dust concentration and humidity. According to the value of the wind design, gas temperature and dust concentration of the process design, the value is slightly less than the value in the technical performance table For principle, the corresponding dust collector model is the required dust collector model.
(2) The gas consumption in the table is the situation when the factory supplies gas centrally. For example, when the air compressor is used alone, the gas consumption in the table should be enlarged to 1.5 times.
(3) In the column of compressed air consumption, the proposed air consumption is the _ air consumption of this type of equipment.
