Abstract

The invention discloses a gas premixing distributor which comprises a gas injection barrel section used for gas injection and a cone diffusion barrel section used for gas mixing and discharging, the lower end of the gas injection barrel section serves as an air inlet, and an outlet of the gas injection barrel section is communicated with the small end of the cone diffusion barrel section. A rotational flow plate assembly used for gas disturbance mixing is arranged at the junction of the gas injection barrel section and the cone diffusion barrel section, a combustion-supporting gas inlet pipeline and a waste gas inlet pipeline are arranged on the gas injection barrel section in the tangential direction, and the combustion-supporting gas inlet pipeline and the waste gas inlet pipeline are located at different height positions of the gas injection barrel section. The three-way inlet air mixing device is simple in structure, convenient to manufacture, small in airflow resistance, capable of effectively enabling three-way inlet air to be mixed relatively uniformly, and wide in application range, and has a turbulence disturbance function.

Description

technical field [0001] The invention relates to the technical field of waste gas combustion premixing, in particular to a gas premixing distributor. Background technique [0002] In engineering projects, for the existing waste gas combustion equipment, the existing equipment requires the combustion temperature to be around 1200°C, which requires controlling the ratio of waste gas, supporting gas and air. In the past, most engineering projects only controlled the ratio of the three gases through the intake air volume, while ignoring the problem of uniform mixing of the three gases. Because of the uneven mixing of Qiqi, it will affect the combustion treatment effect of exhaust gas. Contents of the invention [0003] Technical purpose: To solve the problem of uneven mixing of the three gases in the existing equipment, the present invention adopts a gas premix distributor that can make the three gases evenly mixed before the equipment burns, and finally distribute more evenly...
