Abstract
The invention provides a safety type organic waste gas heat storage type thermal incinerator structure. A heat storage type thermal incinerator comprises an incinerator body and an LEL interlocking cut-off system. The LEL interlocking cut-off system is connected with the incinerator body through an intake manifold. Multiple heat storage bed layers are arranged on the incinerator body. The lower portion of each heat storage bed layer is communicated with a ventilation pipeline. The lower portion of each ventilation pipeline is connected with an air inflow branch, an air outflow branch and a purging branch. The LEL interlocking cut-off system is mainly composed of an LEL combustible gas alarm and a pneumatic emergency cut-off valve. One side of the incinerator body and all the ventilation pipelines are each provided with a round hole. Each round hole is correspondingly and fixedly provided with an explosion-proof sheet. Each air inflow branch, each air outflow branch and each purging branch are each provided with an automatic switchover valve. The safety type organic waste gas heat storage type thermal incinerator structure has the beneficial effects that through multiple explosion-proof control measures of the explosion-proof sheets and the automatic switchover valves, the safety of an RTO incinerator system is improved, and an explosion accident is avoided.
Description
[technical field]
The present invention relates to organic gas abatement equipment field, more particularly, relate to a kind of safety-type organic exhaust gas heat accumulation type thermal incinerator structure.
[background technology]
Chemical enterprise volatile organic waste gas composition is comparatively complicated, is generally multicomponent mist, usually has inflammable and explosive and toxic.The most frequently used volatile organic waste gas treatment facility of current chemical enterprise is heat accumulation type thermal incinerator (RTO), its operation principle is: organic exhaust gas is after regenerator heat absorption heats up, entering combustion chamber high temperature and incinerate (800-1000 DEG C), is that oxidation operation becomes CO
2and H
2inorganic constituents such as O, then store low temperature after heat through another regenerator and arrange outward, the organic exhaust gas that the heat stored newly enters for preheating, keep the stable of fire box temperature through periodic variation airflow direction.This equipment is compared with traditional burning process has purifying rate, hot reclamation rate high (more than 95%), the advantages such as operating cost is low, is current domestic improvement organic exhaust gas comparatively maturation, practical equipment.But due to current organic waste gas treatment equipment security performance not enough, cause several exhaust treatment system explosion accidents occur in recent years, cause society pay attention to.
[summary of the invention]
The technical problem to be solved in the present invention, be to provide a kind of safety-type organic exhaust gas heat accumulation type thermal incinerator structure, by the multiple explosion-proof control measure of anti-rupture disk and automatic transfer valve, improve the security performance of RTO incinerator system, avoid the generation of explosion accident.
The present invention is achieved in that a kind of safety-type organic exhaust gas heat accumulation type thermal incinerator structure, described heat accumulation type thermal incinerator comprises an incinerator body and LEL interlocking cutting system, described LEL interlocking cutting system is connected by inlet manifold with described incinerator body, described incinerator body is provided with a plurality of accumulation of heat bed, each described accumulation of heat bed bottom is all communicated with a vent line, air intake branch is connected with respectively under each described vent line, go out gas branch pipe and blow arm clearly, described LEL interlocks cutting system primarily of LEL flammable gas alarm and pneumatic quick action emergency valve composition, described incinerator body side and each described vent line all offer a circular hole, on each described circular hole, correspondence is fixed with an explosion-proof diaphragm, each described air intake branch, go out gas branch pipe and blow clearly on arm and be equipped with an automatic transfer valve.
Preferably, each described automatic transfer valve by flange with corresponding air intake branch, go out gas branch pipe or blow clearly arm to connect.
Preferably, the described explosion-proof diaphragm on each described vent line is connected with corresponding described vent line by flange.
The invention has the advantages that: when carrying out VOCs treatment, organic exhaust gas first to be interlocked cutting system judge whether the organic exhaust gas concentration being about to enter incinerator body exceedes 1/4th of LEL by flammable gas alarm by LEL, if exceed, then pneumatic emergency stop valve cuts out air inlet immediately, and incinerator body will automatically perform fresh wind cooling action, if do not exceed, then organic exhaust gas will enter incinerator body and carry out high-temperature oxydation degraded, and once abnormal high temperature appears in incinerator body interior or accumulation of heat bed inside, cause incinerator body interior hypertonia, on the vent line of each accumulation of heat bed bottom and the anti-rupture disk of incinerator body side by the pressure release that automatically pops, if pressure release amount only, when incinerator body interior pressure still continues to raise, each automatic transfer valve also will all be opened automatically, common pressure release, reach the object reducing rapidly incinerator body interior pressure, thus avoid the generation of explosion accident.
