Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, a high-power explosion-proof diesel engine includes a diesel engine body, and is characterized in that it also includes an air intake system, an exhaust system and a cooling system, and the air intake system and the exhaust system pass through the pipeline and the air inlet of the diesel engine body respectively. Connect to the air outlet.

[0022] Such as figure 2 As shown, the intake system includes an air-to-air intercooler 15, an intake flame arrester 17, an air shut-off valve 21, an air pre-filter 23 and an air filter 24, and an air pre-filter connected to each other is arranged at the front end of the intake elbow 22. The filter 23 and the air filter 24 filter the dust and particles in the inhaled air through the air pre-filter 23 and the air filter 24 to provide high-quality gas for the diesel engine body. The rear end of th...

Abstract

The invention discloses a high-power explosion-proof diesel engine which comprises a diesel engine body and is characterized by further comprising a gas inlet system, an exhaust system and a cooling system. The gas inlet system and the exhaust system are connected with a gas inlet and a gas outlet of the diesel engine body respectively through pipelines. A cooling liquid circulating pipeline is arranged in the exhaust system, and two ends of the pipeline form a cooling liquid circulating loop through a flow divider and the cooling system respectively. The high-power explosion-proof diesel engine solves the problems in the prior art of large exhaust resistance, large engine power loss, large water consumption, severe environment pollution and the like caused by wet-type discharging of an explosion-proof diesel engine of a large-tonnage mining explosion-proof trackless rubber-tyred vehicle. The explosion-proof diesel engine which is small in exhaust resistance and less in power loss and environment pollution is provided for the large-tonnage mining explosion-proof trackless rubber-tyred vehicle in an underground coal mine.

Description

technical field [0001] The invention belongs to the technical field of transportation vehicles, in particular to a high-power explosion-proof diesel engine. Background technique [0002] The underground conditions of coal mines are special. At present, the high-power explosion-proof diesel engines used in China all adopt wet exhaust gas treatment technology, that is, the exhaust gas is cooled by passing the exhaust gas into water and then discharged. The following disadvantages exist: 1. The exhaust resistance of the exhaust gas is large, which is The power loss of the engine is large 2. When the exhaust gas is discharged, a large amount of water vapor is brought out, the water consumption is large, and water needs to be added frequently, and the large amount of water vapor brought out is very polluting to the environment. Contents of the invention [0003] In order to solve the problems in the prior art that the explosion-proof diesel engine used in the large-tonnage mine...
