baghouse pulse jet dust collectors for gold mining

bag house dust collector is a new type of dust collector with high efficiency at international levels. It combines the advantages of sub-room reverse flow and jet pulse bag house together, which over-comes the weakness of low strength of dedusting, the defects of cleaning dust and filtering which causes dust absorption twice for expanding the application range of bag filter. The collector adopts efficient offline cleaning, which leads to high effectiveness, long service life of filter bag, low resistance, and so on. It is widely used in building materials, metallurgy, chemical industry for purifying dust.
This collector is outdoor type formed by different chambers and filter bag in several kinds of types, which are 32, 64, 96 and 128. The diameter of filter bag is Φ130mm and length 2450mm or 3060mm. Discharging concentration could be less than 20mg/Nm³ if concentration of collecting dust is less than 1000g/Nm³. When outside temperature is less than or equal to
5-25 , the heating device should be installed.
Techinal parameters

Note:

1. The net filtration area in the table refers to the filtration area when a room is cleaned. The total weight of the equipment does not include the weight of the insulation layer.
2. The gas consumption in the table refers to the situation of centralized gas supply in the factory. If a separate air compressor is set, the gas consumption in the table is multiplied by 1.3.

Operation principle :

When the sut gas enters into cloth bag dust collector from air induced system ,due to the decrease of wind speed , the dust particles with a large proportion settle into the ash hopper , and the lighter dust depends on the air induction to reach the surface of dust removal filter bag . The filter nag of dust collector generally uses needle felt as the filter carrier , and the filtration accuracy can reach <1 um , The dust is Blocked on the surface by the filter bag ,and the dust gas is purified through the filter bag .With the increasing of time ,more and more dust filtered on the surface of filter bag , so the resistance of the filter bag is gradually increased .In order to make the dust collector work normally , when the resistance rises to a limited range ,the electronic pulse controller issues instructions to follow the order . The sequence triggers each control valve to open the pulse valve ,and the compressed air in the gas storage bag of dust collector sprayed into the corresponding filter bag by each injection hole of the injection pipe .The filter bag expands rapidly under the instantaneous reverse action of air flow , which makes the filter bag achieve the most original air permeability filtration effect .The cleared dust falls into the ash hopper and drains out the body through the ash removal system to complete the whole ash cleaning and filtration process .
