The function of installing air shower room in purification workshop
Air shower room is the core supporting equipment of purification workshop, also known as air shower door and air shower passage. It is a compulsory purification device before people or materials enter the clean area. Its core function is to effectively remove dust particles attached to the surface of human body, clothes or materials through high-speed clean air flow, and prevent pollutants from the unclean area from entering the clean area, thus maintaining the cleanliness level in the workshop and ensuring the stability of the production environment.
From the perspective of personnel purification, the air shower room is the "first line of defense" in the clean area. Before entering purification workshop, workers need to stand in the air shower room. The equipment will start the high-speed nozzles on both sides or on three sides to spray clean air with high efficiency filtration, and the air flow speed can reach more than 25m/s, which can powerfully purge clothes folds, hair, soles and other places that are easy to hide dirt and shelter dirt, and peel off attached particles such as dust, hair and dander. At the same time, the air shower room is usually equipped with intelligent interlocking function, and the front and rear doors cannot be opened at the same time, which can prevent people from entering the clean area directly without purification, prevent unclean air from infiltrating with the flow of people, and destroy the pressure difference balance and clean environment in the workshop.
In terms of material purification, the air shower room can dust the raw materials, packages and tools that enter the clean area. Some factories will be equipped with cargo shower room (heavy-duty version of air shower room). After the materials enter the cargo shower room through conveyor belt or manual handling, the high-speed airflow can sweep the dust and debris on the surface of the materials to prevent pollutants from entering the production process with the materials. This link is particularly important for environmentally sensitive industries such as electronic chips, precision instruments, pharmaceutical preparations and food processing, which can effectively reduce the product defect rate caused by impurities carried by materials.
In addition, the air shower room can also help maintain the pressure difference stability in purification workshop. The clean area needs to maintain a positive pressure with the non-clean area. The closed structure and air circulation system of the air shower room can reduce the air exchange between the clean area and the outside world and reduce the energy consumption of the air conditioning purification system. At the same time, some air shower rooms are equipped with functions such as filter clogging alarm and adjustable air shower time, which is convenient for managers to adjust purification parameters according to production requirements, improve purification efficiency and prolong the service life of high-efficiency filters.
To sum up, the air shower room has become an indispensable key equipment in purification workshop through three core functions: personnel/material dust removal, airflow blocking and auxiliary pressure difference maintenance, and is an important foundation for ensuring product quality and meeting industry cleanliness standards.
