The operating principle of the utility model three-chamber water-sealing fire-retardant explosion venting device:
When gas tube is normally carried, low concentration gas flows into water seal cavity from water seal cavity gas inlet pipe road, flowing through in water seal cavity after shunting net, after the first connecting line and venting of dust explosion closure gate, enter venting of dust explosion chamber, then flow out whole water seal explosion venting device by gas export line.Now water seal plugging device is in extreme lower position under gas airflow function, and venting of dust explosion closure gate is in open mode under gas airflow function.Water in water seal cavity also flows into water storage cylinder in the effect lower part of gas air-flow, makes the water level of the water table ratio water seal cylinder of water storage cylinder high.
When the generation gas explosion of water seal explosion venting device gas output end, the high pressure draught that blast produces and shock wave enter venting of dust explosion chamber instantaneously, and venting of dust explosion closure gate is closed immediately under differential pressure action, and venting of dust explosion sheet destroys the high pressure draught that release blast produces.Meanwhile, high pressure air blast to act in water storage cavity on the water surface by the second connecting line, water in water storage cavity is pressed in water seal cavity fast, water under high pressure acts on water seal plugging device soffit by shutoff seat, water seal plugging device is lifted instantaneously and blocks the gas inlet pipe road of water seal cavity.Partial high pressure water in water storage cavity also enters the upper surface of water seal plugging device fast by water seal water replenishing pipeline, allow the gas inlet pipe road mouth of pipe moment in water seal cavity be lived by water seal.Under plugging device and water seal acting in conjunction, guarantee that air blast and flame can not enter gas inlet pipe road, avoid igniting fire damp source of the gas.
The control procedure of the utility model three-chamber water-sealing fire-retardant explosion venting device is as follows:
(1), after device power-up, first the initial work such as self-inspection should be completed.
(2) namely device initialize enters Real-Time Monitoring state after completing, namely start by detect water level signal and supplementing water pressure signal real-time Transmission to PLC.PLC, by detecting the signal numerical value that obtains and programmed values contrasts, completes following operation:
1. time as the lowest water level of current level in water seal cavity lower than program setting, PLC opens moisturizing electrical ball valve 8, stops until the water level in water seal cavity reaches program setting water level;
2. time as the peak level of current level in water seal cavity higher than program setting, PLC opens draining electrical ball valve 11, stops until the water level in water seal cavity reaches program setting water level;
3. as supplementing water pressure signal lower than programmed threshold values time, PLC is by flickering display terminal and open acoustic-optic alarm to warn;
4. on display terminal, show the water level in water seal cavity and water storage cavity and supplementing water pressure value in real time.
