Fire-proof and smoke-exhausting variable cross-flow regulating four-way device and anti-dust treatment method

Abstract

The invention discloses a fire-proof and smoke-exhausting variable cross-flow adjusting four-way device and a dust prevention treatment method. The variable cross-shunting adjusting four-way device includes a lower bottom plate, an upper top plate, and side surfaces. The lower bottom plate is divided into high The dust particle concentration area, the medium dust particle concentration area and the low dust particle concentration area; the high dust particle concentration area and the medium dust particle concentration area respectively use anti-dust materials with different roughness heights. This cross shunt regulating cross adopts clean materials with different roughness and height in the parts with different dust concentrations, which can effectively reduce the deposition of suspended particles at the cross cross regulating cross, and at the same time save the amount of wear-resistant materials and reduce the cross shunt regulating four. Common cost.

Description

technical field [0001] The invention belongs to the field of industrial ventilation, and in particular relates to a variable cross-shunt regulating four-way device and a method for preventing dust accumulation of the variable cross-shunt regulating four-way device, in particular to a variable cross-shunt regulating four-way device for fire prevention and smoke exhaust Anti-dust treatment method. 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 roughness of the inner wal...

Problems solved by technology

But in reality, not all parts of the air duct cross diversion adjustment cross are easy to accumulate dust, that is to say, some surfaces that are not easy to accumulate dust or certain parts of the same surface are not easy to accumulate dust. The method of cleaning pipes will inevitably consume excess materials in parts that are not easy to accumulate dust, resulting in an increase in the cost of the entire air duct cross diversion adjustment cross
