Roof natural-ventilation deduster

Abstract

The invention relates to a roof natural-ventilation deduster comprising a roof bracket, an outer guard plate, an inclined bottom plate, a ventilating exhaust outlet, a roofing ventilation opening and an electric switch mechanism, wherein a dedusting exhaust outlet is arranged on the adjacent position of the roof bracket and the ventilating exhaust outlet; a rainproof plate is arranged on a position of the upper part of the roof bracket, which corresponds to the ventilating exhaust outlet and the dedusting exhaust outlet; a ventilating regulation valve plate and a dedusting regulation valve plate are arranged at the ventilating exhaust outlet and the dedusting exhaust outlet; a flow guide plate is arranged on the roof bracket; a flow guide region, a horizontal through-flow dilation region and a back-turning dedusting region are arranged between the roofing ventilation opening and the flow guide plate, between the rainproof plate of the dedusting exhaust outlet and the outer guard plateand between the dedusting exhaust outlet and the horizontal through-flow dilation region respectively; a turnover multilayer dedusting partition plate is arranged in the horizontal through-flow dilation region; a water discharge groove is arranged between the rainproof plate and the outer guard plate; and a dust collection groove is arranged between the outer guard plate and the inclined bottom plate. The invention has the advantages of simple structure, convenience for installation, good ventilating effect, high dedusting efficiency, low energy consumption, energy saving and environment friendliness without noises.

Description

technical field [0001] The invention relates to the field of industrial dust removal, in particular to a roof natural ventilation dust collector. Background technique [0002] The closed roof ventilator is a device that uses the naturally formed air pressure to raise and discharge the air in the building. It has good ventilation performance and complete wind shelter ability, and is widely used in industrial buildings. Although existing roof ventilators have good ventilation performance, they cannot solve the dust removal problem. Although there are many purification and dust removal devices in the production workshops of some factories, they cannot be used or the ideal dust removal effect is not achieved due to the limitation of the production process requirements, so that a large amount of harmful industrial dust is discharged along the roof ventilator. Part of the discharged industrial dust falls on the roof of the workshop, and the other part falls to the farmland with t...

AI Technical Summary

Problems solved by technology

A large amount of dust accumulated on the roof for a long time is not only inconvenient to clean, but also increases the load on the roof and shortens the service life of the factory roof; the dust falling to the land and farmland causes serious pollution of air, water and soil, and destroys the production and living environment of human beings. , a threat to human health

At the same time, each region has strict indicators for industrial dust emissions. Excessive dust emissions limit production and affect the production efficiency of enterprises.
