Measures to reduce energy loss in purification workshops I. Measures adopted in planning 1. The rationality of site selection, construction planning and technical setting can fundamentally reduce initial capital and operating costs. 2, the reduction of purification space is the direction that should be paid attention to the convenience of energy-saving convenience. The air volume of the purification system depends on the volume of the room and the number of air changes, and the number of air changes is mostly determined by the cleanliness level. Therefore, reducing the air volume of the clean system can reduce the space for purifying the space. Because of the low wind quantification, it is possible to reduce the supply power of the wind power by reasonably selecting the number of air changes. Together with the pipeline planning, it may be possible to reduce the resistance of the system, and it can also achieve the effect of reducing the supply of wind power. 3. Accurately determine that the heat load of the production equipment of the purification workshop has a direct relationship with the selected air conditioning and refrigeration equipment. 4, the separation of air conditioning and purification functions is conducive to the performance of their respective skills economic rationality. 5. The heat recovery in the technical process of the purification workshop and the air conditioning system is a direct benefit, so this part of the heat should be fully used to reach the best use of the material. 6. The planning scheme should have good adaptability (sensitivity), which is a question that the experimental workshop needs to think about (such as unidirectional flow/non-unidirectional flow transformation, partition transformation, etc.). 7. The collection of fresh air is conducive to the use of groundwater pre-cooling, dust removal and humidification. 8. The combination between the number of indoor air changes and the final filter power (reaching the same level) requires an economic comparison. Second, the development and use of energy-saving purification equipment 1. The non-separator filter and the new air distribution equipment can form a clean and sensitive purification workshop system. 2. Under the premise of not affecting the noise limit, the advancement of the fan head is conducive to extending the service life of the filter. In addition, the fan should be able to operate at variable speed. 3. The structure (placement and scale) of various purification units should be improved so as to proceed in a direction that is conducive to reducing the volume and improving the uniformity of distribution without adding resistance. 4. Improve the structure of the exhaust cabinet, which is convenient for adjusting the air volume at any time, and convenient operation. Third, the precautions in the operation process 1. When the production operation is suspended, the exhaust cabinet should reduce the amount of exhaust air, and the fresh air volume should be reduced accordingly. 2, according to different technical processes should be able to manipulate the number of indoor ventilation. 3. As in the general air-conditioning system, natural cooling effects may be used at certain times during the operation (outdoor air cooling, cooling towers in winter to obtain cold water). 4. Whether the transition season is to add a new wind ratio, and whether the duty operation method is to start the operation early should be determined through economic comparison. 5. Improve the self-control level of the air-conditioning purification system, and complete the intention of ensuring the quality of operation and reaching energy saving. For large purification workshop equipment, the heating method takes the primary energy cost. Large equipment requires a lot of fresh air and heavy heating. The simplest method of heating is to use an electric resistance heater; however, it is generally the most expensive to produce energy per unit of heat. For large equipment, it is the most useful heating method produced by natural gas or crude oil fuel boilers.
