Application of clean room

Clean engineering mainly concentrates on laboratory, food workshop, operating room, electronic workshop, biopharmaceutical and other fields. For laboratories, the application of clean room will reduce the interference of air particles and ions on the experimental process and improve the experimental accuracy. For the food industry, clean room can minimize the risk of food pollution and improve food safety. For the electronic workshop, the clean room can make the temperature, humidity and particle concentration in the workshop conform to the production standard of electronic components, and ensure the performance and reliability of electronic components.

Principle of purification

Air flow→initial effect purification→humidification section→heating section→table cooling section→medium efficiency purification→fan air supply→pipeline→high efficiency purification air outlet→blowing into the room→taking away particles such as dust bacteria→returning blinds→initial cleaning and repeating Process, you can achieve the purpose of purification.

Building materials for Purification workshop

Clean room walls and roofs generally use 50 mm thick color steel sandwich panels, arc corner, doors, window frames and other general use of special alumina profiles. The ground generally adopts epoxy self-flow floor or high-grade wear-resistant plastic floor. If there is anti-static requirement, anti-static type should be selected. The air supply and return pipeline is made of hot-dip galvanized sheet, and the exterior is made of flame retardant PF foamed plastic sheet. In addition, stainless steel frame and baked aluminium plate for perforated mesh plate are usually used in high efficiency air supply outlet of purification project.

Purification engineering is generally divided into two parts: cleaning dust-free workshop and workshop purification system. The clean room system consists of three basic components: dressing room, air shower room and purification room.

Equipment for clean room

Air shower

The air shower series is a versatile partial clean room equipment installed between the clean room and the non-clean room. When people and goods enter the clean area, they need to be blown through the air shower. The clean air blown out can remove the dust carried by people and goods, and can effectively block or reduce the dust source from entering the clean area. The front and rear doors of the air shower are electronically interlocked and act as air locks to prevent unpurified air from entering the clean area.

Transfer window

The transfer window is mainly suitable for the transfer of small goods between the clean area and the non-clean area, or between the clean room and the clean room, which can effectively reduce the number of opening of the purification workshop door and minimize the pollution of the clean area. According to the requirements of use, the surface of the transfer window box can be sprayed, and the inner tank can be made of stainless steel, which is beautiful in appearance. The two doors of the transfer window adopt electronic control interlock or mechanical interlocking device, which can effectively prevent dust from entering the high clean area in the low clean grade zone, which is an essential equipment for the clean room.

Efficient air supply

This equipment is 10,000-class, 100,000-class turbulent clean room newly built, and the reconstruction project cleans the air-conditioning system terminal air supply device. The device is mainly composed of a static pressure box, a high-efficiency filter, an aluminum alloy diffusion plate, a standard flange interface, etc. The utility model has the advantages of beautiful appearance, simple structure and reliable use. The air supply port of the device is a bottom-loading type, which has the advantages of convenient installation and replacement of the filter in the clean room. The high-efficiency filter adopts mechanical pressing or liquid tank sealing device to ensure that the air outlet is installed without leakage, the sealing is reliable, and the purification effect is good.

Clean workbench

The clean workbench in the purification workshop can maintain high cleanliness local purification on the console according to product requirements or other requirements. The clean workbench can form a sterile, dust-free partial purification in the local space of the console. The main components are pre-filter, high-efficiency filter, fan unit, outer casing, static pressure box, countertop and supporting electrical components.

FFU fan filter unit

The Fan Filter Unit (FFU) is an air self-cleaning device that can be mounted on an indoor ceiling or placed on a stand to achieve a local level of 100. It can also be used for air supply at the end of a clean room. The device is equipped with an initial and high efficiency two-stage filtration device. The fan draws in air from the top and filters through the primary and high efficiency filters. The filtered clean air is sent out through the entire air outlet. There are two types of mounting methods: hanging and floor stand.

Laminar flow hood

Laminar flow hood An air purification device that provides a locally high clean environment. It mainly has cabinets, fans, primary air filters, and high efficiency air filters.
