Embodiment 1

[0024] The dual-tube centrifugal axial flow fan vehicle exhaust emission device of the present invention includes a vehicle exhaust pipe, a drainage pipe 1 and a bellows. The bellows includes a stainless steel bellows and a plastic bellows, two each; the drainage pipe 1 A T-shaped three-way structure is adopted, in which two parallel ports on the same pipe are respectively connected to a stainless steel corrugated pipe 2, and the last port is connected to a vehicle exhaust pipe; one end of the stainless steel corrugated pipe is connected to the drainage pipe 1, and the other end is connected Plastic corrugated pipe. There are two plastic corrugated pipes, one is a long plastic corrugated pipe 3, and the other is a short plastic corrugated pipe. It also includes an axial flow fan 4 which is connected to the long plastic corrugated pipe 3. The length of the stainless steel bellows 2 is greater than or equal to 8 meters. The diameter of the stainless steel bellows 2 is smaller t...

Embodiment 2

[0025] The difference between Embodiment 2 and Embodiment 1 is:

[0026] The double-row pipe centrifugal axial flow fan vehicle exhaust emission device and its use method of the present invention include the following steps. Step 1: Survey the site in advance and determine the length of the two plastic bellows, the long plastic bellows and the short plastic bellows. The long plastic corrugated pipe 3 is a moving part, and its length is equal to the maximum distance required during the movement of the vehicle; the short plastic corrugated pipe is a working part, and its pipe length is equal to the shortest exhaust distance after the vehicle is placed in place; Step 2: According to the vehicle exhaust For the number and size of the air pipes, reserve exhaust gas discharge holes on the side of the converter transformer; Step 3: Before the vehicle enters the valve hall, insert the exhaust device into the vehicle exhaust pipe, and use high temperature resistant tapes to seal tightly. ...

Abstract

The invention discloses a double-exhaust pipe centrifugal axial-flow fan vehicle tail gas discharge device and an application method thereof. The exhaust device comprises a vehicle exhaust pipe, and further comprises a drainage pipe (1), a corrugated pipe and an axial-flow fan; the corrugated pipe includes two stainless steel corrugated pipes and two plastic corrugated pipes; the drainage pipe (1) adopts a T-shaped three-way structure, wherein two parallel ports positioned on the same one pipe are respectively connected with the two stainless steel corrugated pipes, and the final port is connected with the vehicle exhaust pipe; one ends of the stainless steel corrugated pipes are both connected with the drainage pipe (1), and the other ends are both connected with the plastic corrugated pipes; two plastic corrugated pipes are provided; one is a long plastic corrugated pipe, and the other one is a short plastic pipe; and the axial-flow fan is connected with the long plastic corrugated pipe. The application method comprises the following steps: (1) the scene is surveyed beforehand to determine the lengths of the two plastic corrugated pipes; the long plastic corrugated pipe belongs to a movable piece; and the length of the long plastic corrugated pipe is equal to a maximum distance needed in the vehicle moving process.

Description

Technical field [0001] The invention relates to a tail gas discharge device and a method of use thereof, in particular to a method of use of a double-row pipe centrifugal axial flow fan vehicle tail gas discharge device. Background technique [0002] In previous projects, if it is necessary to replace the converter valve side casing, the large-scale company needs to pull the faulty converter out of the operating position, and complete the replacement of the faulty casing on the outdoor open space. Outdoor replacement will affect the construction environment. Very demanding. Part of the converter valve side casing of the Tianshan converter station needs to be replaced. However, because the site is located on the Gobi Desert in Xinjiang, sandstorms are extremely frequent. Outdoor hoisting cannot control the construction environment. A slight accidental sandstorm blows into the converter body. Will cause major equipment accidents. Therefore, the traditional method of replacing the...
