Dust-free purification workshop has been very popular, almost all walks of life, including: precision electronics, food industry, medical operating room and so on. The service quality of the products and production work of the industry has been significantly improved, to meet the requirements of the working environment, improve the work efficiency and work quality. What details should be paid attention to in the use of dust-free purification workshop? Follow Shanghai Lijing to have a look.

8 details of purification workshop that can not be ignored

1, the final filter efficiency: under a certain amount of indoor dust, the use of high efficiency filter, can reduce the airflow speed. In order to save energy, the filter with higher efficiency can be considered to reduce the airflow velocity. Or use a lower efficiency filter, increase the airflow speed, in order to minimize the product of flow and resistance.

2. The air duct requires both economy and efficiency: in the purification project, the air duct should be both economic and effective air supply. Economic requirements are reflected in low operating cost, convenient construction, smooth inner surface and small resistance. Efficiency refers to no dust, good tightness, no air leakage, fire resistance, no dust, no pollution, corrosion resistance, moisture resistance.

3, fire alarm equipment and telephone can not be less. Set up a telephone in the purification workshop, intercom phone, reduce personnel walking in the clean area, reduce the amount of dust, in case of fire, timely contact with the outside, but also create conditions for normal work contact. In addition, the dust-free purification workshop should also set up a fire alarm system to prevent the fire from being found by the outside, which will cause significant economic losses.

4, automatic control device to ensure full regulation. Some manufacturers use manual way to adjust the air volume and pressure, but control the air volume and pressure of the regulating valve are in the technical layer, and the ceiling is also the soft ceiling of color steel plate, basically in the installation and debugging adjustment, after that, most of the no adjustment, in fact, can not be adjusted. To ensure the normal production of clean workshop dust-free purification workshop project and work, shall set up a set of relatively complete automatic control device, implement the following functions: clean room air cleanliness, temperature and humidity, differential pressure control, air valve adjustment, high purity gases, pure water and cooling water temperature, pressure, flow testing, gas purity, pure water, water quality monitoring, etc.

5. Control requirements for self-cleaning time: the release or interruption of pollutants or air flow in the clean room or the intermittent convective air flow or the movement of people and equipment during normal operation will cause the deterioration of cleanliness. The self-cleaning time to restore to the original cleanliness is determined by the air flow speed; The CONTROL REQUIREMENTS FOR SELF-CLEANING TIME DEPEND ON THE ABILITY TO WITHSTAND THE IMPACT ON THE QUALITY AND yield of product production within this time frame (under deteriorating cleanliness).

6, air conditioning purification should pay attention to energy saving. Air conditioning in purification workshop consumes a lot of energy, so energy-saving measures should be taken in design and construction. In the design, air supply calculation, system and area division, temperature and relative temperature determination, clean level and air change times determination, fresh air ratio, duct insulation, duct production in the bite form of the air leakage rate, dry pipe branch pipe connection Angle on the influence of airflow resistance, Whether the flange connection is air leakage and the selection of air conditioning box, fan, chiller and other equipment are all related to energy consumption.

7. Indoor air flow pattern and distribution: unidirectional flow requires uniform and equal streamlines, but it will be interfered by process equipment layout, position changes and personnel activities, forming local eddy currents, instead of unidirectional flow requiring mixing, to avoid dead corners and temperature stratification.

8. Indoor pollution sources: building components, the number of personnel and operation activities, process equipment, process materials and process processing itself are dust emission sources, which vary greatly according to the specific situation.
