1, the last filter efficiency: a certain amount of indoor dust, the use of high-efficiency filters, can reduce the air velocity. In order to save energy can consider the use of higher efficiency filters, reduce the air velocity; or the use of lower efficiency filters, improve the air velocity, in order to minimize the product of flow and resistance.
2, the air duct requirements of economy and efficiency: purification project, the air duct should be both economic and effective air supply. Economic requirements are reflected in the running costs and low prices, easy to construct, smooth inner surface resistance. Efficiency means no dust, good tightness, no air leakage, can be fire-resistant, no dust, no pollution, corrosion resistance, moisture resistance.
3, fire alarm equipment and telephone can not be less. In the clean room plant set up a telephone, intercom telephone, reduce the number of people walking in the clean area, reduce the amount of dust, in case of fire in a timely manner with the outside world, but also to create conditions for normal work contact. In addition, the clean room should also set up fire alarm system to prevent fire is not easy to be found outside, thus causing significant economic losses.
4, self-control devices to ensure that the whole process of regulation. Some manufacturers use manual way to adjust the wind volume and wind pressure, but control the wind volume and wind pressure of the adjustment valve are in the technical compartment, and the ceiling are also color plate soft ceiling, basically in the installation and commissioning of the adjustment, since then, most did not adjust, in fact, can not be adjusted. In order to ensure the normal production and work of the clean plant of the dust-free purification workshop project, a more complete set of self-control devices should be set up to achieve the following functions: clean room air cleanliness, temperature and humidity, differential pressure monitoring, air valve adjustment, high purity gas, pure water and circulating cooling water temperature, pressure, flow rate detection, gas purity, pure water water quality monitoring and so on.
5, self-cleaning time control requirements: clean room release or bring in pollutants or air flow interruption or normal operation of intermittent convection airflow or people and equipment movement will cause deterioration of cleanliness, back to the original cleanliness of the self-cleaning time is determined by the speed of the airflow; self-cleaning time control requirements depend on the time frame (deterioration of the cleanliness of the), the quality of product production and the ability to withstand the impact of the rate of finished products. And finished product rate impact on the ability to withstand
6, air-conditioning purification need to focus on energy saving. Purification workshop air conditioning energy consumption is very large, design and construction need to take energy-saving measures. In the design, air supply calculation, the system and the division of the region, the temperature and relative temperature determination, clean level and the determination of the number of air changes, the new air ratio, duct insulation, duct production in the form of bite leakage rate of air leakage rate of the impact of the dry pipe branch connection angle of air resistance, flange connection leakage, etc., as well as air-conditioning box, fan, chiller and other equipment selection is not related to energy consumption.
7, indoor air flow and distribution: unidirectional flow requires uniform, equal flow lines, but will be subject to the arrangement of process equipment as well as changes in location and personnel activities, such as interference, the formation of local vortex, while the non-unidirectional flow requirements of the mix, to avoid the dead zone and temperature stratification.
8, indoor sources of pollution: building components, the number of personnel and operational activities, process equipment, process materials and process processing itself are dust particles release source, according to the specific circumstances vary, change greatly.
The above is a common 8 purification workshop design and use of the problems to be considered, if you have any other questions or want to build a purification dust-free workshop, please consult the Kunshan Qingyang Purification Engineering Co!
