Problems solved by technology
[0004] At present, the exhaust gas cooling and purification water pipes in China can meet the requirements of the above-ground flat roadway test, but cannot meet the complex road conditions and long-term continuous use requirements in coal mines, thereby greatly reducing the power performance of the explosion-proof diesel engine and increasing the fuel consumption of the explosion-proof diesel engine. In addition, the exhaust gas purification effect is not good. Air Quality in Polluted Roadways

The invention discloses an exhaust gas cooling and purifying water pipe for an explosion-proof diesel engine. The mixing pipe is provided with a water replenishing hole for supplying liquid water into the mixing pipe; the upper end of the amplifying pipe is connected with the mixing pipe through a throat pipe, and the lower end is connected with a water washing sleeve arranged on the outside thereof, the said The bottom end of the washing sleeve is connected to the bottom plate; the lower end of the amplifying pipe is provided with a number of first filter holes in the circumferential direction; the airflow guide plate is arranged on the inner side below the amplifying pipe and above the bottom plate, and the lower end of the Connected with the water washing sleeve, the lower end of the airflow guide plate is provided with a plurality of second filter holes in the circumferential direction. The above-mentioned exhaust gas cooling and purification water pipe has better cooling and purification effects on the exhaust gas, and can meet the use requirements of complex road conditions in coal mines.
Description
technical field [0001] The invention relates to the technical field of explosion-proof diesel engine components, in particular to an exhaust gas cooling and purifying water pipe for an explosion-proof diesel engine. Background technique [0002] Explosion-proof diesel engine for coal mine is a diesel engine used in underground mine tunnels containing methane or combustible dust. It has explosion-proof performance. It will not ignite ambient gas and dust when working in an explosive environment, and the emission gas index meets the requirements of special environmental regulations. , It is usually used as an explosion-proof power device for various fixed or mobile equipment in coal mines. [0003] Exhaust gas cooling and purification water pipe is the core device to lead the exhaust gas of the explosion-proof diesel engine used in coal mines to below the water level of the cooling and purification water tank, and fully wash the exhaust gas to achieve flame extinguishing, cool...
