Embodiment Construction
[0012] Such as figure 1 As shown, a high-temperature ventilation duct includes a duct body 1 and an air inlet arranged on the side wall of the duct body 1. The duct body 1 is provided with a deflector 3 for separating the inner cavity of the duct inner body 1 into two cavities. , one of the cavities is the main flue 4, the other cavity is the auxiliary flue 5, the bottom of the auxiliary flue 5 is closed by the partition 6 connected between the side wall of the pipe body 1 and the diversion partition 3, and the The tuyere 2 is arranged on the side wall of the pipe body 1 on the side where the auxiliary flue 5 is located, the inner wall of the pipe body 1 is provided with a smooth layer 7, and the outer wall of the pipe body 1 is provided with an insulation layer 8; Sound-absorbing layer 9 is arranged, and smooth layer 7 adopts fireproof board to make.

The invention discloses a high-temperature ventilating pipeline, which comprises a pipeline body and an air inlet arranged on the side wall of the pipeline body. A flow guiding plate for dividing an pipeline body inner cavity into two cavities is arranged in the pipeline body, one of the cavities is a main flue, the other cavity is an auxiliary flue, the bottom of the auxiliary flue is closed through a partition plate connected between the side wall of the pipeline body and the flow guiding partition plate, and the air inlet is arranged on the side wall of the pipeline body on the side where the auxiliary flue is located. The high-temperature ventilating pipeline is characterized in that a smooth layer is arranged on the inner side wall of the pipeline body, and a heat preserving layer is arranged on the outer wall of the pipeline body. The high-temperature ventilating pipeline has the advantages of effectively preventing dust and particles from being adhered to the inner wall of the pipeline body, enabling smoke in the pipeline to be kept in a certain temperature range within a certain period of time and reducing noise of a ventilating duct greatly.
Description
technical field [0001] The invention relates to a pipeline, in particular to a high-temperature ventilation pipeline. Background technique [0002] Most of the traditional high-temperature ventilation pipes are made of cement, which has poor fire resistance and is not high-resistant. And the current ventilation duct improved for this reason is not very ideal in heat preservation and sound insulation, and the service life is also extremely short. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide a high-temperature ventilation duct with good thermal insulation effect, low noise and long service life in view of the above deficiencies. [0004] The technical scheme adopted in the present invention is: [0005] A high-temperature ventilation duct, comprising a duct body and an air inlet arranged on the side wall of the duct body, the duct body is pro...
