The invention belongs to the technical field of exhaust gas treatment of explosion-proof diesel engines, and in particular relates to a novel exhaust noise reduction and purification device for explosion-proof diesel engines. It solves the problem of high exhaust emission noise of explosion-proof diesel engines, including a box filled with purification medium, diffuser chamber I, diffuser chamber II, muffler I and muffler II, and the box is respectively equipped with air inlet and The exhaust port and the air inlet are connected to the diffuser chamber I, and the muffler I and the muffler II are arranged in the box. It is connected with the diffuser chamber I set in the box; the muffler II includes a shell and perforated tube III and perforated tube IV set inside the shell, the perforated tube IV is connected with the diffuser cavity II set in the box, and the diffuser cavity II is in communication with the box body; a muffler connecting pipe is connected between the perforated pipe II and the perforated pipe III, and the muffler I and the muffler II are completely immersed in the purification medium in the box.
Description
technical field [0001] The invention belongs to the technical field of exhaust gas treatment of explosion-proof diesel engines, and in particular relates to a novel exhaust noise reduction and purification device for explosion-proof diesel engines. Background technique [0002] Explosion-proof rubber-tyred vehicles have become the main equipment for trackless auxiliary transportation in coal mines. As the main power source of explosion-proof rubber-tyred vehicles, explosion-proof diesel engines are more and more used in underground explosion-proof rubber-tyred vehicles. At present, due to explosion-proof requirements, the exhaust emissions of explosion-proof diesel engines are generally treated by exhaust gas treatment devices, which have many disadvantages: 1. Explosion-proof rubber-tyred vehicles generally have poor sealing performance and the distance between the driver and the explosion-proof diesel engine is relatively close, and the general exhaust gas treatment device...
