Title:

MIXING DEVICE FOR GAS FLOWS WITH DIFFERENT FLOW RATES AND PHYSICAL PROPERTIES IN A PIPE

Document Type and Number:

WIPO Patent Application WO/2022/002084

Kind Code:

A1

Abstract:

The invention discloses a mixing device for gas flows with different flow rates and physical properties in a pipe. The device comprises a T-type mixing pipe structure, the T-type mixing pipe structure comprises a first pipe 1 and a second pipe 2, the first pipe is used for circulation of a fluid with a high flow rate, the second pipe is used for circulation of a fluid with a low flow rate, the second pipe penetrates the first pipe and extends to the inside of the first pipe to form a pipe extension portion, and the pipe extension portion is provided with an opening 3 on the incident flow side of the second pipe, and a number of first jet orifices 4 are provided on the wall surfaces of the pipe extension portion corresponding to the two sides of the opening. The mixing device achieves pre-mixing by means of the pipe extension portion, and the p re-mixed fluid passes the first jet orifices to increase the speed of the pre-mixed fluid. Further, the first jet orifices are located on the wall surfaces on the two sides of the opening, so the collision of the ejected fluid with the outer pipe wall will change the streamline, and promote downstream turbulent disturbance and re-mixing, thereby greatly improving the mixing effect of a gas flow with a high flow rate and a gas flow with a low flow rate.
