Tail gas emission cooling device for explosion-proof diesel engine

Abstract

The invention relates to a tail gas emission cooling device for an explosion-proof diesel engine. The main structure of the tail gas emission cooling device comprises a first water tank, a second water tank, an exhaust tank, an air inlet, an air inlet horizontal pipe, an exhaust hole, an exhaust horizontal pipe, a water level sensor, a water level controller, an observation window and a pipe cap; based on a mechanical and water cooling temperature reduction structure, tail gas firstly enters the first water tank to be cooled, and then enters the second water tank to be cooled and finally is discharged by the exhaust box, the water level sensor is used for acquiring water level information, and the water level controller is connected with an external water source and automatically supplements water to keep water in the two tanks sufficient. The tail gas emission cooling device has the advantages of advanced design, compact structure, convenience for installation and use, good use effect, capability of reducing the temperature of tail gas to below 70 DEG C from 600 DEG C, and good safety, stability and reliability and is a very ideal tail gas emission cooling device for an explosion-proof diesel engine.

Description

Technical field [0001] The invention relates to an explosion-proof diesel engine tail gas emission cooling device, which belongs to the technical field of explosion-proof diesel engine parts of auxiliary transportation equipment underground in coal mines. Background technique [0002] A large number of mining auxiliary transportation equipment is used in coal mines. Most of the power machinery used by these equipment is explosion-proof diesel engines. The explosion-proof diesel engines will produce a large amount of exhaust gas during operation. Most of these exhaust gases have a high temperature, around 600°C and high heat. The exhaust gas discharged into the narrow tunnel space will not only pollute the environment, but also bring potential safety hazards and cause accidents. Therefore, the exhaust gas of the explosion-proof diesel engine must be quickly cooled down to below 70°C during the emission process, so as to ensure the downhole equipment and Operator safety.

Problems solved by technology

[0002] A large number of mining auxiliary transportation equipment are used in coal mines. Most of the power machinery used by these equipments are explosion-proof diesel engines. Explosion-proof diesel engines will generate a large amount of exhaust gas during operation. Exhaust gas is discharged into the narrow roadway space, which not only pollutes the environment, but also brings safety hazards and accidents. Therefore, the exhaust gas of the explosion-proof diesel engine must be cooled rapidly during the discharge process, and the temperature must be lowered to below 70°C. Only in this way can the underground equipment and equipment be guaranteed. operator safety
