Waste gas treatment box of mining anti-explosion diesel engine

Abstract

The invention relates to a waste gas treatment box of a mining anti-explosion diesel engine. The waste gas treatment box comprises a box body, a fire barrier, a mounting support, a gas inlet, a gas inlet pipe, a gas discharging port, a gas discharging pipe, a water injection hole, a water discharging hole, a liquid level sensor and a waste gas temperature sensor, wherein the box body is mainly used for storing water, the liquid level sensor is used for monitoring the water level inside the box body, the fire barrier is used for eliminating sparks in discharged gas, the waste gas temperature sensor is used for monitoring the temperature of the discharged gas, and the mounting support is used when connected with an engine. Thread explosion-separation design is respectively adopted by the water injection hole and the water discharging hole, the gas inlet pipe and the gas discharging pipe are arranged inside the box body and communicated with the gas inlet hole and the gas discharging hole respectively, wherein the gas inlet pipe extends from the upper portion of the box body to the bottom of the box body, a furcation structure is adopted by the lower portion of the gas inlet pipe, and a plurality of through holes are formed in the pipe wall of the furcation structure at the lower end of the gas inlet pipe. The waste gas treatment box of the mining anti-explosion diesel engine is large in water storage capacity, the effects of cooling and sound-eliminating can be improved, the contact area of the waste gas and water is enlarged, the gas discharging resistance is reduced, and the sparks are fully eliminated.

Description

technical field [0001] The invention relates to an exhaust gas treatment box of an explosion-proof diesel engine, in particular to an exhaust gas treatment box applied to an explosion-proof diesel engine locomotive in a coal mine. Background technique [0002] At present, explosion-proof diesel engines are mainly used in explosive places such as coal mines to provide power for underground transportation equipment such as trackless rubber-tyred vehicles, monorail cranes, and trucks. Since the explosion-proof diesel engine will produce a large amount of exhaust gas when it is working, the exhaust gas contains nitrogen oxides (NO x ), carbon monoxide (CO), hydrocarbons (HC) and solid particulates (PM) and other harmful substances, and the exhaust gas will generate a lot of noise when it is discharged, so the explosion-proof diesel engine needs to be equipped with an exhaust gas treatment box to treat the exhaust gas discharged during work to process. The traditional exhaust g...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of the exhaust gas treatment box of the existing mine explosion-proof diesel engine, and provide a new structure of the mine explosion-proof diesel engine exhaust gas treatment box. The technical problem to be solved is to make it pass through the air intake pipe The lower part of the intake pipe adopts a bifurcated design, which can divide the exhaust gas into at least two channels for cooling and silencing respectively, which improves the effect of cooling and silencing. resistance, fully eliminate sparks, and further reduce exhaust noise, very suitable for practical
