What should be paid attention to in the design of air purification project? The purification project is a whole, and every link should be carefully checked. Only by doing well in every detail can the whole system be improved and brought into full play. How to do these well, the following eight points need our attention.
1. Purification system
Indoor air purification system can be divided into horizontal laminar flow, vertical laminar flow and turbulent flow. The choice of air flow mode is based on the Convention and the working parameters of the room.
2. Cleanliness and air change frequency of cleaning engineering
The cleanliness of the room depends on the ventilation rate per unit time. Therefore, the technical parameters of the purification system should be determined after careful consideration of the working nature of the room and the production process requirements.
3. Purification engineering structure
In order to prevent the accumulation of dust in the room, the structure must be carefully designed to prevent air flow from accumulating.
4. Design scheme of purification project
In order to determine the design scheme, it is necessary to carefully consider the working nature of the room and the air flow conditions in it. The workshop with large dust emission should not adopt the form of ground air supply, and the workshop with high cleanliness requirements should be as far away from other workshops as possible.
5. Purification materials
As the ceiling of clean room, the wall and floor must be made of materials that are not easy to crack, particles and dust. In addition, according to the different working conditions of the room, it is also necessary to consider whether the chemical properties of the materials are stable.
6. Pressure and air flow in purification engineering
In order to ensure the cleanliness of the room, it is necessary to prevent the air pollution from outside into the room. To achieve this goal, the room must maintain positive pressure. In order to obtain the required room pressure, appropriate fresh air must be supplied.
7. Purification auxiliary equipment
If necessary, some auxiliary equipment should be installed, such as the air indicator of the new air outlet, the transmission window on the partition, etc. These devices must be suitable for the requirements of the room and must really understand its function.
8. Control of human and material in purification
People and objects are the main dust sources of the clean room, so it must be fully controlled. For example, before entering the purification room, all people should go through the personal purification system, change the dust-free clothes, and receive the basic education on the functions of the purification system.
9. Water supply and drainage and air supply device and power supply of purification project
According to the workshop to be operated, necessary water supply and drainage devices, air supply devices and power supply shall be provided. These devices and equipment involved must be easy to use and design, and shall not be superior to the air purification system.
