Waste gas treatment device for gas-steam boiler

Abstract

The invention discloses a waste gas treatment device for a gas-steam boiler, which comprises a treatment box, an induced draft fan is fixedly connected to the lower part of the left side surface of the treatment box; and the output end of the induced draft fan is fixedly communicates with the interior of the treatment box, a water conveying pipe is fixedly embedded in the inner top wall of the treatment box, a water spraying pipe is fixedly communicates with the bottom face of the water conveying pipe, water spraying holes arranged at equal intervals are formed in the bottom face of the waterspraying pipe, and two symmetrical fixing blocks are fixedly connected to the inner top wall of the treatment box. The invention discloses the waste gas treatment device for the gas-steam boiler, through a water outlet pipe, a valve used in cooperation, water in the treatment box can be effectively discharged; and by arranging a water spraying pipe and cooperatively using a water spraying hole, apush plate, a sealing gasket, a strong spring, a ventilation groove and a third fixing plate, exhausted waste gas can be effectively treated, pollution of the waste gas to the environment is reduced,and the problem that waste gas emission of an existing gas-steam boiler does not reach the standard is solved.

Description

technical field [0001] The invention relates to the technical field of steam, in particular to a waste gas treatment device for a gas-fired steam boiler. Background technique [0002] Gas-fired steam boiler refers to a steam boiler that uses gas combustion to heat. The vertical steam boiler adopts the method of placing the burner below, with a two-pass structure. The fuel is fully burned, the boiler operates stably and takes up less space. Smoke exhaust speed increases heat transfer, boiler thermal efficiency is high, and user costs are reduced; the horizontal steam boiler is a shell-type full-wet backflow three-pass pyrotechnic tube structure, and the flame burns in a small positive pressure in the large combustion chamber and is fully extended. The combustion heat load is low, the combustion heat efficiency is high, which effectively reduces the exhaust gas temperature, saves energy and reduces consumption, and is more economical to use. The corrugated furnace and threaded...
