Embodiment 1

[0085] Specific embodiments of the present invention are provided below, and it should be noted that the present invention is not limited to the following specific embodiments, and all equivalent transformations done on the basis of the technical solutions of the present application all fall within the scope of protection of the present invention.

[0086] According to the above technical scheme, the cross-sections of the inlet and outlet of the rectangular progressively expanding resistance member in this embodiment are 320mm×250mm and 630mm×500mm respectively, and the materials of the upper top plate, lower bottom plate, side a and side b are steel plates, and the roughness height is uniform. For K=0.15mm, a 2m long straight pipe section is connected to the front end of the elbow inlet, and a 2m long straight pipe section is connected to the rear end of the outlet. According to the "Code for Design of Heating, Ventilation and Air Conditioning in Civil Buildings", the wind spe...

Abstract

The invention discloses a smoke-proof low-resistance industrial ventilation rectangular gradually expanding resistance member, which comprises an upper top board, a lower bottom board, a side board a and a side board b; the upper top board, the lower bottom board, the side board a and the side board b are four The sides are enclosed to obtain a rectangular expanding pipe; the upper top plate and the lower bottom plate are the same; the side plate a is the same as the side plate b; 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 gradually expanding resistance member adopts clean materials with different roughness and height at different dust concentrations, which can effectively reduce the deposition of suspended particles at the elbow, save the amount of wear-resistant materials, and reduce the cost of the gradually expanding resistance member.

Description

technical field [0001] The invention belongs to the field of industrial ventilation, and in particular relates to a progressively expanding resistance component and a treatment method for preventing smoke and reducing resistance thereof, in particular to a rectangular gradually expanding resistance component and a treatment method for preventing smoke and reducing resistance of the gradually expanding resistance component. Background technique [0002] 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...
