High-power explosion-proof diesel engine

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...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems in the prior art that the explosion-proof diesel engine used in the large-tonnage mine-used explosion-proof trackless rubber-tyred vehicle adopts wet discharge to cause large exhaust resistance, large loss of engine power, large water consumption, and serious environmental pollution, the present invention provides a Explosion-proof diesel engine used for large-tonnage mining explosion-proof trackless rubber-tyred vehicles in coal mines with low exhaust resistance, low power loss, and low environmental pollution
