Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Referring to fig. 1-3, the present invention provides an exhaust cooling water jacket device, including: cooling water sleeve 1, the cover is located high-temperature gas in cooling water sleeve 1 and is let in from the front end and follow rear end exhaust blast pipe 2, wherein, water inlet 101 has been seted up to cooling water sleeve 1's front end, the cooling water that forms the confession that communicates water inlet 101 between inner wall and the 2 outer walls of blast pipe flows along 2 length direction of blast pipe 2 and carries out cooling water cavity 3 once to the high-temperature gas in blast pipe 2 that the confession that feeds into from water inlet 101, cooling water cavity 3 that the rear end of cooling water sleeve 1 still is provided with a plurality of atomizing holes 1021 that communicate with cooling water cavity 3, can discharge the cooling water in cooling water cavity 3 with vaporific mode, make vaporific cooling water can mix with the high-temperature gas after the cooling once of blast pipe 2 exhaust, carry out secondary cooling to the high-temperature gas after once cooling.
Specifically, the water baffle 102 is arranged at the position, corresponding to the cooling water cavity 3, of the rear end of the cooling water sleeve 1, and the atomizing holes 1021 are formed in the water baffle 102.
