Brief introduction of WC type low pressure Venturi dust collector:
WC type low voltage Venturi dust catcher is Beijing Nonferrous Metallurgy Design and Research Institute was an efficient wet dust collector research and design reference and relevant information of foreign equipment. DW is a type of improved products.
After several years of application practice, it is proved that the equipment can be widely used in the occasion of high dust removal efficiency, and can also be used as a washing and purification of harmful gases.
Structure and principle of WC type low pressure Venturi filter:
The principle is: the dust laden gas in the dome of the passage and the outflow from the water supply tank, and the water contact with the weir flow along the Venturi pipe wall. A small water droplet is formed due to the increase of the air velocity at the throat opening, and the dust is directly put into the water surface of the sedimentation tank because of the collision of the dust and the water droplets. Less particles are brought into the cyclone by gas. The cyclone can also play a role of dehydration.
Run
1, due to the use of water dust, the operation should be antifreeze;
2, adjust the water supply pipe valve, water spray water column for 2cm with appropriate;
3, adjust the filter bottom valve opening degree, so that the running overflow pipe has a small amount of water overflow;
4, for water saving, can be recycled.
The use of WC type low pressure Venturi filter:
The dust collector has passed the appraisal, the appraisal opinion is: "the design is reasonable, the performance is advanced, the quality is qualified, the user is good".
The equipment in the manufacture of artificial dust test, Beijing Nonferrous Metallurgy Design Institute and the iron and Steel Institute of labor hygiene has been measured, the dust removal efficiency is 98-99.88%.
The dust removal efficiency of a copper mine and the basic ceramic was measured, and the dust removal efficiency was 99.17% and 99.99% respectively.
At present, the dust collector is widely used in mineral processing factory, ceramics factory, printing and dyeing, copper, lead-zinc, pit crushing, radioceramics factory, gold, casting workshop, crematorium and boiler dust.
Characteristics of WC type low pressure Venturi dust collector:
1, the device is actually two dust, efficiency as high as 99%;
2, the dust collector resistance is 127mmH2O, the power consumption is little;
3, the entrance of the highest concentration of dust concentration up to 35g/m3, strong adaptability;
4, parts standardization, low cost;
5, due to the formation of a water film Venturi tube, resulting in a small wear, long life;
6, tight hole, easy to open. As long as the open into the hole, all parts of the equipment can be touched, easy to clean up;
7, water outlet of large diameter, low requirements on water quality, no blockage;
8, water pressure is greater than 0.1kg/cm2 can be.
9, covers an area of small, convenient installation, reliable operation, almost no maintenance, no wearing parts;
10, the export of gas without water phenomenon
