Abstract

The invention discloses a deposition prevention type ventilating pneumatic conveying pipeline dovetail tee joint and a deposition prevention treatment method. The dovetail tee joint comprises an inlet, an inner arc face a, a lower bottom plate a, an outlet, an outer arc face a, an upper top plate a, an upper top plate b, an outer arc face b, a flange, a lower bottom plate b and an inner arc face b. The lower bottom plate a, the lower bottom plate b, the outer arc face a and the outer arc face b are each divided into a high dust particle concentration area, a middle dust particle concentration area and a lower dust particle concentration area. Dust deposition prevention materials different in roughness height are adopted in the high dust particle concentration areas and the middle dust particle concentration areas. Clean materials different in roughness height are adopted at the positions different in dust deposition concentration, and therefore deposition of suspended particulate matter at the dovetail tee joint can be effectively reduced, meanwhile, the number of adopted wear-proof materials is decreased, and the manufacturing cost of the dovetail tee joint is reduced.

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...
