Problems solved by technology

[0003] At home and abroad, the engine explosion-proof technology is immature and faces many technical problems, especially after the exhaust system is treated with explosion-proof treatment, the power loss is large (the water-based type loses 20%, and the explosion-proof grille type loses 15%), which is uneconomical to use. At the same time, the exhaust system is often blocked by smoke and dust in the exhaust gas, resulting in greater power loss until failure

Embodiment Construction

[0013] The explosion-proof engine exhaust system shown in Figure 1 is composed of a water-jacketed three-way exhaust pipe 4, an air extractor 7, a water tank 9, water, an engine speed sensor 2 and a control system 6. The air inlet of the water-jacketed three-way exhaust pipe 4 is connected to the exhaust gas outlet of the engine, one of the exhaust ports is provided with a flameproof grille 1, and the other exhaust port is provided with an active air extraction system. The water jacket of the water-jacketed three-way exhaust pipe 4 has a cooling water inlet 3 and a cooling water outlet 5, and the cooling water flows through the water jacket to cool the three-way exhaust pipe to reduce and cool the surface temperature of the exhaust pipe. , so that the surface of the exhaust pipe meets the requirements of Class I explosion-proof. The active air extraction system has an air extractor 7, a water tank 9, water, an engine speed sensor 2 and a control system 6, the inlet of the air ...

Abstract

The invention discloses an explosion proof type exhaust system for an engine which is provided with a water jacket tee joint structure which is directly connected with an engine exhaust pipe; and one exhaust port of the water jacket tee joint is provided with an explosion proof grid and the other exhaust port is provided with an active air exhaust system. Compared with the prior art, the explosion proof type exhaust system has the advantages that: the power loss of the engine is small, and oil is saved; higher requirement of an explosion proof grade is met, and the harsher working conditions are accorded with; the exhaust system is not needed to be cleaned, so that the loss caused by halt is reduced; and noise is lower and the air can be exhausted better.

Description

technical field [0001] The invention relates to the technical field of engine exhaust systems, in particular to an engine exhaust system used in inflammable and explosive places, and is a novel explosion-proof engine exhaust system. Background technique [0002] With the rapid development of my country's social and economic construction, large-scale chemical industry, oil refining, coal mines, natural gas transportation, natural gas mining, coal bed methane mining, shale gas mining, oil mining and storage bases continue to emerge, all of which have an impact on the explosion-proof technology of related vehicle engines higher requirements. [0003] At home and abroad, the engine explosion-proof technology is immature and faces many technical problems, especially after the exhaust system is treated with explosion-proof treatment, the power loss is large (the water-based type loses 20%, and the explosion-proof grille type loses 15%), which is uneconomical to use. At the same ti...
