Abstract

The invention discloses an anti-sediment type ventilated pneumatic conveying pipeline dovetail tee and a dust-proof treatment method. The dovetail tee includes an inlet, an inner arc surface a, a lower bottom plate a, an outlet, an outer arc surface a, an upper top plate a, Top plate b, outer arc surface b, flange, lower bottom plate b, and inner arc surface b; lower bottom plate a, lower bottom plate b, outer arc surface a, and outer arc surface b are all divided into areas with high dust particle concentration and medium dust particle concentration. Concentration area and low dust particle concentration area; the high dust particle concentration area and the medium dust particle concentration area use anti-dust materials with different roughness heights respectively. The present invention adopts clean materials with different roughness and height in the parts with different dust concentration, which can effectively reduce the deposition of suspended particles at the dovetail tee, save the amount of wear-resistant materials used, and reduce the cost of the dovetail tee.

Description

technical field [0001] The invention belongs to the field of industrial ventilation, and in particular relates to a dovetail tee and an anti-dust treatment method, in particular to a dovetail tee and an anti-dust treatment method for an industrial ventilation anti-deposition type ventilation pneumatic conveying pipeline. Background technique [0002] The dovetail tee is an indispensable part of the industrial ventilation distribution system. When the outdoor air in the air supply system is processed by the air conditioning unit, since most coarse and fine filters can only filter suspended particles above 3um, the fine particles will directly enter the air duct with the wind, and the actual roughness of the inner surface of the air duct is much higher. Due to the size of the fine particles, these fine particles will accumulate more and more electrostatic adsorption as the air and the inner wall of the air duct collide and rub against each other, which will cause the roughness...
