Problems solved by technology

[0005] 1) When the usual intercooler air intake system is in use, the gas intake manifold entering each cylinder may be tempered and shot, and the flame generated by the tempering is instantly transmitted to the air outlet cavity of the intercooler, directly turning the ordinary copper tube copper The chip is burned out, which reduces the air intake efficiency and cooling effect of the intercooler. What's more, the copper pipe is burned out and water leaks into the cylinder, resulting in a cylinder jacking accident;
[0006] 2) When the intercooler intake system is in use, the gas intake manifold entering each cylinder may be backfired, and the flames at the same time will heat the intake air cooled by the intercooler system, which will further lead to the failure of the intercooler system

Embodiment 1

[0062] In this embodiment, the first gas outlet fire arresting structure includes:

[0063] The first gas outlet flame arrester seat 11, the first gas outlet flame arrester seat 11 is set at the end of the cooling water cavity 9 close to the gas outlet, the outer diameter of the first gas outlet flame arrester seat 11 is fitted to the inner diameter of the cooling water cavity 9 , when the first outlet flame arrester seat 11 is in use, it is attached to the inner wall of the cooling water chamber 9, thereby ensuring that the flame will not spread between the first outlet flame arrester seat 11 and the cooling water chamber 9; and

[0064] At least one first gas outlet flame arrester core 12, the first gas outlet flame arrester core 12 is fixed in the first gas outlet flame arrester seat 11, when in use, by setting different numbers of first gas outlet flame arrester cores 12 to Increase fire extinguishing effect;

[0065] The second gas outlet fire arresting structure include...

Embodiment 2

[0071] As a preferred embodiment of Embodiment 1, in this embodiment, an air outlet intermediate spacer ring 14 is arranged between the first air outlet flame arrester core 12 and the second air outlet flame arrester core 15; The inner wall of the first gas outlet flame arrester seat 11 and the second gas outlet flame arrester seat 16 are connected. The spacer ring 14 in the air outlet can effectively ensure that there is a gap between the first air outlet flame arrester core 12 and the second air outlet flame arrester core 15. The second outlet flame arrester seat ring 16 is connected so that it becomes a whole and is easy to disassemble.

Embodiment 3

[0073] As a preferred embodiment of the above embodiment, in this embodiment, the intercooler and the air outlet are detachably connected, so in order to ensure the airtightness of the intercooler, an air outlet seal is provided at the connection between the intercooler and the air outlet Circle 13.

[0074] An air outlet sealing ring 13 is also arranged at the communication part between the intercooler and the air outlet;

Abstract

The invention discloses an explosion-preventing flame-retarding intercooler and a gas engine device comprising the same. The explosion-preventing flame-retarding intercooler comprises an intercoolingpart; the intercooler further comprises an air inlet part and an air outlet part; the air outlet part comprises an air outlet shell, a first air outlet fire-retarding structure and a second air outletfire-retarding structure; and the first air outlet fire-retarding structure is arranged between an air outlet and a cooler core, the second air outlet fire-retarding structure comprises at least onesecond air outlet fire-retarding device core which are arranged in parallel, and a certain gap is formed between the first air outlet fire-retarding structure and the second air outlet fire-retardingstructure. According to the explosion-preventing flame-retarding intercooler, through the arrangement of the first air outlet fire-retarding structure and the second air outlet fire-retarding structure, the problem that when a gas inlet main pipe entering cylinders backfires, the flame generated by backfire is instantaneously transferred to an intercooler air outlet cavity, and common copper pipesand common copper sheets are directly burnt out can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of engine equipment, in particular to an explosion-proof and flame-retardant intercooler. Furthermore, it also relates to a gas engine arrangement. Background technique [0002] Gas engine is an engine that uses green and environment-friendly natural gas as clean fuel. It has been rapidly developed in the fields of automobile, land power generation, ship power and ocean engineering. Intercooling technology and explosion-proof intake system, which affect the performance and safety of natural gas engines, have always been the focus of attention of developers and customers. [0003] However, the intercooled explosion-proof intake system of the existing gas engine is generally in accordance with the traditional diesel engine intercooled intake system mode, only by adding a gas mixer before or after the boost, or adding a gas injection valve on the intake manifold, In order to realize the premixed supercharge...
