Ventilating device

Abstract

The invention discloses a ventilating device. The ventilating device comprises an air supply fan, an air supply pipe, an exhaust fan and an exhaust pipe. The ventilating device is characterized by further comprising an air-supply static pressure box and an exhaust static pressure box, wherein an air outlet of the air supply fan is connected with an air inlet of the air-supply static pressure box by the air supply pipe; and an air outlet of the exhaust static pressure box is connected with an air inlet of the exhaust fan by the exhaust pipe. The ventilating device disclosed by the invention has the advantages that the structure is simple, the cost is low, the industrial pollution is controlled by utilizing air jetting, the control range of pollutants is large, the capture efficiency is high, the purposes of effectively controlling industrial pollution and protecting the occupational health are achieved, and simultaneously the energy is furthest saved.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device for controlling indoor environmental pollution of industrial buildings. Background technique [0002] With the increasing calls for occupational health protection, people pay more and more attention to the health of workers. However, in industrial buildings, process production usually produces a large amount of pollutants. In order to protect the occupational health of workers, it is necessary to ventilate the process workshop . In the prior art, in order to control the indoor environmental pollution of industrial buildings, local ventilation is usually used, that is, a suction hood is installed near the pollution source, and the suction hood is connected to the exhaust fan through the air duct, and the pollutants are sucked in by the suction of the exhaust fan. Exhaust hood and vent. This kind of suction hood can only achieve pollution control under specific conditi...

AI Technical Summary

Problems solved by technology

This kind of suction hood can only achieve pollution control under specific conditions such as close proximity to pollution sources. However, actual site conditions often cannot meet these regulations, resulting in the loss of control of indoor environmental pollution in industrial buildings by such existing devices. , so that a large amount of pollutants generated during the process of production spread to other areas of the workshop or other workshops, and the health of workers working in these areas cannot be effectively protected

In addition to the small pollutant control range and relatively low pollutant collection efficiency, the suction hood also has problems such as large ventilation volume and high energy consumption.
