Abstract
The invention discloses two-in-one converging pipe which comprises a first branch pipe, a second branch pipe and a converging pipe. The first branch pipe comprises a first reducing section and a first body section. The second branch pipe comprises a second reducing section and a second body section. One end of the first reducing section is communicated with the first body section, and the other end of the first reducing section is communicated with the converging pipe. One end of the second reducing section is communicated with the second body section, and the other end of the second reducing section is communicated with the converging pipe. The adjacent sides of the first reducing section and the second reducing section are communicated. The cross section of the first body section, the cross section of the second body section and the cross section of the converging pipe are round. The fullness of smoke in the two-in-one converging pipe is high, a flow field is even, and therefore noise caused by vibration of a smoke duct body can be avoided. The resistance, obtained through simulation and calculation by adopting the fluent fluid simulation software, of the two-in-one converging pipe is small and is about 60 Pa, and energy consumption can be effectively reduced. In addition, compared with a traditional two-in-one converging pipe, material consumption of the two-in-one converging pipe is greatly reduced. The invention further discloses a smoke duct.
