A Ventilation System for Containing Contaminant Escape from Open Paint Spaces

Abstract

The invention discloses a ventilation system for suppressing the escape of pollutants in an open paint spraying space. The periphery of the open painting space; the air flowing through the open painting space and the periphery of the open painting space forms a polluted airflow and enters the purification and separation system, in which the separation airflow with high pollutant concentration and the purification airflow with low pollutant concentration are formed. Air flow, the separated air flow with high pollutant concentration is discharged through the exhaust air flow through the mechanical exhaust system, and the purified air flow with low pollutant concentration is sent to the mechanical air supply system and the air curtain air supply system respectively by the circulating air supply system. The fresh air supply system described above forms a fresh air stream and sends it into the mechanical air supply system. The invention realizes the linkage between the operation of the ventilation system and the dynamic change of the concentration of pollutants in the environment, and reduces the power consumption and air consumption of the ventilation system during the painting process in an open space.

Description

technical field [0001] The invention belongs to the technical field of industrial ventilation, and in particular relates to a ventilation system for suppressing the escape of pollutants in an open paint spraying space. Background technique [0002] Paint spraying is an essential production link in the manufacture of automobiles, airplanes, ships, etc., accompanied by the generation of toxic pollutants such as a large amount of organic gases and paint mist particles. Especially when the paint spraying operation takes place in an open space, the hidden dangers of accidents caused by the escape of toxic pollutants, such as workers' health and safety, and plant fire and explosion protection, are more serious. Therefore, the development of an efficient ventilation system to suppress the escape of toxic pollutants generated by spray painting in open spaces has great engineering value for ensuring the health and safety of industrial environments and production safety.

AI Technical Summary

Problems solved by technology

It should be pointed out that the pollutants generated by painting are attenuated dynamically in a closed space. If the mechanical ventilation system is operated under the condition of large air volume, it will cause serious air waste and power consumption.

In addition, by setting up physical barriers to close the partial space for painting, the utilization rate of workshop space and the convenience of painting operations are greatly reduced
