Eye drops purification plant purification and layout

The air purification of the eye drop purification plant adopts the air filtration method. When the dust-laden air passes through the porous filter medium, the dust is trapped by the micropores or adsorbed by the pore wall to achieve the purpose of separation from the air; the air filter mainly has 3 First-efficiency, medium-efficiency and high-efficiency air filters, air filters are often used in series, the main function of the primary-efficiency and medium-efficiency filters is to protect the high-efficiency filter and prolong its service life; the air cleanliness is 100,000 or higher than 10 For the air purification treatment of 10,000 grades, three-stage filtration of primary, medium, and high-efficiency air filters should be used. Among them, the air purification treatment of grade 100,000 can also be replaced by sub-high-efficiency air filters.

The purification air-conditioning system filters and purifies the air, and performs various treatments such as heating and cooling, humidification or dehumidification. After a comprehensive analysis of specific conditions, an economical and applicable plan can be selected; the operation of the purification air-conditioning system should be scientifically managed to ensure that Purify plant usage requirements, and achieve maximum energy saving. The layout of the clean room should be in line with the requirements of the process conditions to better improve the purification efficiency. The room or area with high cleanliness should not be too large or too high, and should be arranged in the place where the least number of people can reach, and should be close to the air-conditioning room; Rooms or areas with different cleanliness levels should be arranged from inside to outside according to the level of air cleanliness; rooms or areas with the same air cleanliness should be arranged relatively centrally; cleanrooms should be arranged inside or in the center of the workshop, or closed in the middle. External corridor buffer form; the interconnection between rooms with different air cleanliness should have facilities to prevent pollution, such as air locks, air showers or transfer windows. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for eye drop purification plants and clean plants.

The windows, ceilings of the purification workshop and the connecting parts of the pipes, air vents, lamps and walls or ceilings entering the room should be sealed. The static pressure difference between adjacent rooms with different air cleanliness levels should be greater than 5Pa. The static pressure difference of the outdoor atmosphere should be greater than 10Pa, and there should be a device to indicate the pressure difference; the clean area should be provided with sufficient lighting according to production requirements. Lighting, the workshop should be equipped with emergency lighting facilities; the clean room should maintain a fresh air volume of not less than 40m3 per person per hour, and the fresh air volume should be 2%-4% of the total air supply volume of the one-way flow clean room. The flow clean room should be 10%-30% of the total air supply.

When designing the eye drop purification plant, the process layout should avoid the cross-travel of personnel and logistics; try to prevent unnecessary entry of inspectors or control personnel, and its 100-level clean room environment should be able to see all operations from the outside; In critical filling areas, such as the filling area of u200bu200bclass 100 clean workbenches, physical barriers should be considered to restrict entry of outsiders; personnel changing rooms should be designed as airlock rooms, with different changing stages separated to prevent microbial contamination and particulate contamination caused by clothing reduced to a minimum. The layout of each part of the clean room must be in line with the requirements of the production process, and the flow direction of personnel, logistics and air flow must be clarified to ensure the cleanliness of the clean room. The flow of personnel entering the clean room is: outer dressing room → washing room → Locker room → air shower room → quasi-clean room.
