Several suggestions for the field of traditional compressed air purification

In the past, when building a compressed air system, people often ignored the impact of pollutants in the compressed air on the system, and only considered the simple economic factors such as initial investment and operating energy costs, thus ignoring the impact of compressed air quality that is not up to standard. Huge invisible waste, and these losses often greatly exceed the purchase and operating costs of high-quality compressed air purification equipment. Perhaps many companies think that even if the compressed air purification equipment is almost a bit, it has little effect, or that the water in the compressed air has no effect, but what about it?

　　 The water content in compressed air will have a serious impact on the air equipment, such as shortened service life, decreased accuracy, increased failure rate, poor quality, etc., which will have a great impact on the safety, quality, and cost of the enterprise. Up to now, less than 5% of the companies in my country have reached the standard for compressed air, and the remaining 95% of the companies have an astronomical amount of cost and waste of resources due to the annual non-compliance of compressed air. However, these still have not caused many Manufacturing companies make changes.

From the perspective of purchase cost, good compressed air purification equipment must be more expensive than ordinary equipment. Of course, the corresponding later maintenance process will be relatively reduced. On the contrary, although the purchase cost of ordinary purification equipment is low, the latter is due to insufficient air source. Pneumatic component replacement costs caused by compliance, equipment failure, downtime loss, loss of defective products, shortened life of pneumatic equipment, equipment depreciation costs, etc., all costs can be combined, you can buy a lot of high-quality compressed air purification equipment .

　　Compressed air purification equipment generally refers to compressed air dryers and compressed air filters.

Compressed air purification equipment is a basic equipment in modern industry, and its energy consumption accounts for about 10% to 35% of the total energy consumption of the factory. That is to say, all companies are basically equipped with compressed air purification equipment, and the company believes that there are already purification equipment. No need to modify, as long as it can be used, there is no need to replace and upgrade. The use of purification equipment that meets the gas requirements of enterprises, with more stable performance and energy saving, can not only improve the overall technological level of the enterprise, but also greatly reduce the production cost of the enterprise, and it also responds to the national call for energy conservation and emission reduction.

　　Some people believe that selecting a single filter corresponding to the processing accuracy according to the required air quality can meet the requirements and save money. In fact, it is not. Although the required air quality is determined by the processing accuracy of the selected single filter, there is no pretreatment protection of the pre-lower-level filter, and the high-precision filter element will soon be clogged due to excessive load. This also speeds up the replacement frequency of the filter element, thereby increasing production costs in disguise. This principle is the same as the drainage of a river. A river will only increase the degree of silt clogging. If there are multiple tributaries to share, it will disperse the pressure on one tributary.

　　 It can be seen that the disadvantages of the traditional compressed air purification field are still great. If you want to improve this situation, the dryer manufacturers have summarized the following suggestions:

　　 1. Compressed air should be as clean and dry as possible without excess water;

　　2. Compared with the comprehensive cost, the purification equipment with low price is not as effective as the good purification equipment. When choosing, choose the purification equipment with low comprehensive cost as much as possible;

　　3. If there is already a relatively traditional purification equipment, if it is not fully equipped, it can be upgraded appropriately to reduce the overall cost and achieve the effect of energy saving and emission reduction;

4. If you want to better filter out the pollutants in the compressed air, you should be equipped with a complete filter instead of a single filter, which not only achieves the quality of the compressed air, but also reduces the load of the single filter. The cost of frequent replacement due to large blockage;

5. For the replacement of the filter element, it is not to say that no replacement is the best way to save costs, nor is it to say that it is frequently replaced, but to replace the filter element at the right time to ensure low power consumption and production costs, and reduce environmental impact. Burden.
