Background technology
The useless flue gas that when coke oven machine side is coaling, its burner overflows just can reach discharge standard by incinerator Thorough combustion, and the pipeline supplying combustion-supporting gas in incinerator leads to when burning fire door place must install explosion hazard gases pipeline fire retardant device additional.But existing various flammable explosive gas pipeline fire retardant device internal structure is complicated on market, because of its model, specification and pressure rating are comparatively fixing, so for the operating mode type selecting of loine pressure instability and Application comparison difficulty, and price comparison is expensive, for the purity of the flammable explosive gas as fuel and quality requirement strict, if when fuel medium purity is low or impurity is more, back-fire relief equipment entrance end face very easily blocks, cause fuel can not normal supply and cannot burning, thus cause incinerator to be stopped transport and the coke oven flue gas that gives up just emptying without Thorough combustion, cause the pollution of environment, harm personal safety and healthy, and increase the production costs such as maintenance and improvement.
Summary of the invention
The pipeline operating mode of coke oven incinerator combustion-supporting gas of loine pressure instability, fuel attribute complexity is not suitable in order to solve existing anti-explosion fire arrester, and it is expensive, complicated, the technical problem of type selecting and application difficult, the invention provides a kind of hydrolock anti-explosion fire arrester.
The technical scheme that technical solution problem of the present invention is taked is as follows:
Hydrolock anti-explosion fire arrester, is characterized in that: this device comprises water level autocontrol instrument, fuel gas inlet adapter, water inlet pipe, storage tank, flange, bursting diaphragm, fuel gas outlet adapter, gauge manifold and overflow pipe; Bursting diaphragm is connected in the top end opening place of storage tank and is sealed by the top end opening of storage tank by described flange, and water inlet pipe and gauge manifold are all arranged with the epimere of storage tank and in the inner space of storage tank; Fuel gas inlet adapter and fuel gas outlet adapter all arrange and storage tank middle epimere and in the inner space of storage tank;
The port of export of described fuel gas outlet adapter is provided with the first elbow, the arrival end of fuel gas inlet adapter is provided with the second elbow, and described first elbow and the second elbow are all arranged in the inner chamber of storage tank, and, the opening upwards of the first elbow, Open Side Down for the second elbow;
Described overflow pipe comprises the horizontal tube and VERTICAL TUBE that run through storage tank sidewall, at a right angle and connected by elbow both it; The middle hypomere with storage tank arranged by horizontal tube, and its position is lower than the height of the second elbow on storage tank sidewall; The port of VERTICAL TUBE extends and presses close to the bottom of storage tank;
The liquid level tube of described water level autocontrol instrument is vertically arranged in the sidewall outside of storage tank, the epimere of liquid level tube and lower end are respectively by the inner space of upper communicating pipe and lower communicating tube and storage tank, and the height of described upper communicating pipe is lower than the height of horizontal tube on storage tank sidewall but higher than the port height of the second elbow; The bottom of storage tank is pressed close in the position on storage tank sidewall of lower communicating tube.
The invention has the beneficial effects as follows: this hydrolock anti-explosion fire arrester can adapt to well loine pressure instability, fuel attribute complexity the device such as coke oven incinerator to the anti-explosion fire-retardant requirement of the pipeline of explosion hazard gases, in addition also to have structure simple, with low cost for this device, easy to operate, reliable, be convenient to advantages such as popularizing.
