Abstract

The invention belongs to the technical field of downhole explosion-proof diesel engines in coal mines, and provides an exhaust gas treatment device for with a good treatment effect for a composite explosion-proof diesel engine. The exhaust gas treatment device comprises a box body, a partition plate is arranged in the box body, the box body is partitioned into a water washing chamber and a floating ball chamber by the partition plate, and a gap for allowing tail gas to pass is reserved between the upper portion of the partition plate and the box body; a flame arrester chamber located in the box body is arranged on one side of the water washing chamber, a water sleeve is arranged between the flame arrester chamber and the box body, the water washing chamber is internally provided with a built-in exhaust cylinder and a sound attenuation cavity, one end of the exhaust cylinder communicates with an exhaust opening of the flame arrester chamber, and the other end of the exhaust cylinder communicates with the sound attenuation cavity; the floating ball chamber is internally provided with a water level control valve and a water level sensor, and a second sound attenuation plate and a water baffle are fixed to the upper portion of the floating ball chamber, wherein a plurality of through holes are formed in the surface of the second sound attenuation plate; the bottom of the water baffle is located on the lower portion of the second sound attenuation plate; and an exhaust chamber is formed by the second sound attenuation plate, the water baffle and the box body. The exhaust gas treatment device can be widely applied to the field of the downhole explosion-proof diesel engines in the coal mines.

Description

technical field [0001] The invention relates to a dry-wet combined explosion-proof diesel engine exhaust gas cooling and noise reduction device, which belongs to the field of key technical components supporting explosion-proof diesel engines in coal mines. Background technique [0002] The exhaust gas temperature of the explosion-proof diesel engine in the coal mine shall not be higher than 70°C, the surface temperature of the explosion-proof diesel engine and its supporting components shall not be higher than 150°C, and sparks shall not be discharged to avoid detonating the underground explosive gas. At present, the coal mine waste gas treatment device generally adopts dry type or wet type. The dry type treatment device uses the cooling water of the explosion-proof diesel engine itself to contact the exhaust gas indirectly for heat exchange, and the air mixer sucks in cooling air to cool the exhaust gas. The cooled exhaust gas passes through the flame arrester for explosion ...
