What is the purification equipment commonly used in purification projects?1. Air shower room:The air shower is a necessary purification equipment for workers to enter a clean and dust-free workshop. It has strong versatility and can be used with all clean rooms and clean workshops. When workers enter the workshop, they must pass through this equipment and use strong clean air, which is sprayed onto people from all directions by a rotatable nozzle, effectively and quickly removing dust, hair, dandruff, and other debris attached to clothes. It can reduce the pollution problems caused by people entering and exiting the clean room. The two doors of the air shower are electronically interlocked and can also function as an airlock to prevent external pollution and unpurified air from entering the clean area. Prevent workers from bringing hair, dust, and bacteria into the workshop, meet strict dust-free purification standards in the workplace, and produce high-quality products. 2. Transfer window: The transfer window is divided into the standard transfer window and the air shower transfer window. The standard transfer window is mainly used to transfer items between clean rooms and non-clean rooms to reduce the number of door openings. It is the best purification equipment to effectively reduce cross-contamination between clean rooms and non-clean rooms. The transfer windows and doors are all double-door interlocking (that is, only one door can be opened at a time, and after one door is opened, the other door cannot be opened). Depending on the material of the box, the transfer window can be divided into stainless steel transfer window, stainless steel transfer window inside the outer steel plate, etc. The transfer window can also be equipped with a germicidal lamp (8W), intercom, etc. 3. Air shower transfer window: The air shower transfer window is an auxiliary equipment for the clean room. To reduce the large amount of dust particles caused by the entry and exit of goods, the clean air flow filtered by the high-efficiency filter of the air shower transfer window is sprayed onto the goods from all directions by rotatable nozzles. , effectively and quickly remove dust particles. The cleared dust particles are filtered by primary and high-efficiency filters and recirculated into the air shower area. To achieve the best effect of showering, the wind speed at the nozzle outlet can reach more than 20 seconds. 1. Air shower transfer windows can be divided into air shower transfer windows and floor-standing air shower transfer windows according to their structures; 2. The air shower transfer window can be divided into stainless steel air shower transfer window, stainless steel air shower transfer window inside the outer steel plate, etc. (the inner liner of the transfer window is all sand-faced stainless steel); 3. The transfer window can be divided into electronic interlocking air shower transfer windows and mechanical interlocking air shower transfer windows according to different interlocking methods. 4. FFU fan filter unit: The full English name of FFU (Fan Filter Unit) has the characteristics of modular connection and use. There are two stages of primary and high-efficiency filters respectively. The working principle is: that the fan inhales air from the top of the FFU and filters it through primary and high-efficiency filters. The filtered clean air is evenly sent out through the air outlet surface at an average wind speed of 0.45m/s. The FFU fan filter unit adopts a lightweight structural design and can be installed by the Grid system of various manufacturers. The structural size design of the FFU can also be changed according to the Grid system. The diffuser plate is installed inside, the wind pressure is spread evenly, and the wind speed on the air outlet surface is average and stable. The metal structure of the downwind duct will never age. Prevent secondary pollution, the surface is smooth, the wind resistance is low, and the sound insulation effect is excellent. Special air inlet duct design reduces pressure loss and noise generation. The motor has high efficiency and the system consumes low current, saving energy costs. The single-phase motor provides three-stage speed regulation, which can increase or decrease the wind speed and air volume according to actual conditions. According to customer requirements, it can be used as a single unit or connected in series to form multiple 100-level production lines. Control methods such as electronic board speed regulation, gear speed regulation, and computer centralized control can be used. It has the characteristics of energy saving, stable operation, low noise, and digital adjustment. It is widely used in electronics, optics, national defense, laboratories, hospitals, and other places that have air cleanliness requirements. It can also be assembled into various sizes of static 100-300,000-level products using support frame structural parts, anti-static curtains, etc. A clean work shed is very suitable for building a small area of clean area, which can save money and time in building a clean room. 1. FFU purification level: static level 100; 2. FFU wind speed is: 0.3/0.35/0.4/0.45/0.5m/s, FFU noise ≤46dB, FFU power supply is 220V, 50Hz. ; 3. FFU adopts a high-efficiency filter without partitions, and the FFU filtration efficiency is 99.99%, ensuring the purification level; 4. The FFU is made entirely of high-quality galvanized sheets; 5. The FFU step-less speed regulation design has stable speed regulation performance. The FFU can still ensure that the air volume remains unchanged under the final resistance of the high-efficiency filter; 6. FFU uses high-efficiency centrifugal fans, which have a long life, low noise, maintenance-free and low vibration; 7. FFU is particularly suitable for assembly into ultra-clean production lines. It can be arranged as a single FFU according to process needs, or multiple FFUs can be used to form a 100-level assembly line. 5. Laminar flow hood: The laminar flow hood is mainly composed of a box, a fan, a high-efficiency air filter, a coarse-efficiency filter, a porous plate, and a controller. The cold plate of the outer shell is sprayed with plastic or a stainless steel plate. The laminar flow hood passes the air through the high-efficiency filter at a certain speed to form a uniform flow layer, allowing the clean air to flow vertically in one direction, thereby ensuring that the high cleanliness required by the process is met in the work area. It is an air purification unit that can provide a local clean environment and can be flexibly installed above process points that require high cleanliness. The clean laminar flow hood can be used alone or combined into a strip-shaped clean area. The laminar flow hood can be hung or supported on the ground. It has a compact structure and is easy to use. 1. Laminar flow hood purification level: static level 100, dust with particle size ≥0.5m in the working area ≤3.5 particles/liter (FS209E100 level); 2. The average wind speed of the laminar flow hood is 0.3-0.5m/s, the noise is ≤64dB, and the power supply is 220V, 50Hz. ; 3.
