石家庄DMC bag type pulse dust collector

Working principle:

The equipment is usually composed of three parts: the upper cylinder body (clean gas chamber), the middle cylinder body (mixing chamber) and the lower cone. Dust from the air inlet air into the cylinder, severely diminished because of sudden expansion velocity of airflow volume, larger particles under the action of its weight from the settlement of dust in the air down cone, smaller particles due to the screen of filter bag filter, collision, diffusion, under the action of static electricity, and many other effects, by hysteresis resistance on the outside of the filter bag, after purification of gas, through the filter bag venturi tube from barrel on discharging mouth eduction. When hysteresis resistance on the outside of the filter bag dust particles increases, the dust resistance increasing, in order to reduce resistance, controlled by the pulse meter sends a signal to open the electromagnetic pulse valve, gets the body of the compressed air spray by the injection hole injection on the torch to the corresponding venturi tube (primary air), and high speed air flow through the venturi tube, Induced several times of the primary wind surrounding air (secondary wind) into the filter bag, resulting in rapid expansion of the filter bag, due to the impact of reverse pulse airflow quickly disappeared, the filter bag and rapid contraction, such expansion and contraction make the accumulation of excess dust particles attached to the outer wall of the filter bag is cleaned, falling particles discharged from the lower cone. Since soot is respectively to the several groups of filter bag, not cutting off to deal with the dust of the air, so in the process of dust removal, the processing capacity of dust collector remains the same, pulse interval and width and cycle according to the nature of the particles, dust concentration and of the specific conditions of the filtration speed adjustment, is a normal working condition of equipment.

Performance characteristics:

1. There are many types of equipment, the intake pipe can be entered from the lower cylinder and the middle cylinder: the frame of the filter bag (keel) has single and multi-stage, the material is stainless steel and carbon steel, the filter bag has common and three-proof (waterproof, oil-proof, high-temperature proof) material, in order to adapt to the needs of different users.

2. Filter bag adopts special connection structure, so it has good sealing performance, easy to clean and change.

3. The equipment is reliable, high dust removal efficiency, large air volume, is an indispensable equipment in industrial production to eliminate pollution, protect the environment, improve working conditions, recovery of useful materials, can be widely used in metallurgy, electronics, chemical, mineral, pigment, pharmaceutical, food, building materials, food processing and other industries.
