Purification system for inorganic coating spraying room

Abstract

The invention provides a purification system for an inorganic coating spraying room, which comprises an air purification system and a temperature and humidity control system, wherein the air purification system consists of an air blast subsystem and an air exhaust subsystem. The air blast subsystem comprises a blower, a filter-element filter, a liquid adsorption filter and an air feeder, which are connected in sequence by pipes; and the air inlet of the blower is communicated with the atmosphere directly. The air exhaust subsystem comprises an exhaust fan and a blow-off valve which are connected in sequence by pipes; the exhaust fan is arranged outside a water curtain type filter arranged in the spraying room; the blow-off valve is directly communicated with the atmosphere; and the air quantity exhausted by the blow-off valve is less than that blasted by the blower. The purification system is capable of leading the air environment to meet the requirements on cleanliness and humidity in spraying of inorganic coatings, and is also applicable in the conditions with bigger spraying workpieces and larger needed space. The purification system can maintain positive pressure of the spraying room and prevent outside air from entering, and is provided with a circulating water system simultaneously, thus being capable of dissolving paint mist. The purification system completely realizes automatic control, has simple structure and convenient operation, and is safe and environment-friendly.

Description

technical field [0001] It involves the field of coating production and processing, specifically the air environment control of the production environment of inorganic coatings, mainly including the control of air cleanliness and temperature and humidity. Background technique [0002] Inorganic coating spraying process is a new generation of surface treatment technology developed in modern times. This process has high requirements on environmental conditions. Among them, the air cleanliness requires that the dust particle size must be less than 0.5 μm, and the dust concentration must be less than 5 particles / m 3 ;The temperature must be controlled within the range of 18-25°C; the humidity must be controlled within the range of 40-60%, so the spraying construction must be carried out in the clean room. [0003] However, various traditional industrial purification rooms generally only have the functions of air purification and temperature control, but do not have the function o...

AI Technical Summary

Problems solved by technology

If it is to spray a large workpiece, due to its large production area, its manufacturing cost will be high and its control will be very difficult

In the production of inorganic coatings, it is easy to generate paint mist and dust, which are not only easy to deposit on the spraying surface, affecting the quality of spraying, but also generally spraying materials have certain damage to the human body, threatening the health of spraying operators
