Description

Technical Field

[0001] The invention relates to the technical field of filters, and in particular to an assembled filter for a machine room. Background Art

[0002] The water system room is a room that relies on a circulating water system for temperature regulation. Existing water system rooms are mostly built in an assembled manner, which features high precision, fast construction speed, less material waste, clean construction environment, energy conservation and environmental protection. In the water system room, the temperature and humidity are controlled through the cooperation of the circulating water system and the air conditioning system. Specifically, the circulating water system consists of a circulating pump, a water tank and a water cooler. The air conditioning system also participates in the temperature and humidity regulation of the room. The system includes components such as condensers, evaporators, fans, air conditioning boxes and delivery pipelines. In the process of inhaling external air, the air needs to be preliminarily treated to ensure that the air meets the standards and avoid affecting the life of the equipment.

[0003] However, there are still some problems in the existing filters during the initial treatment of air:

[0004] 1. The gaps in the outer filter of traditional filters are relatively large, which makes it easy for dust particles in the air to penetrate the filter and then invade the storage area of ​​the adsorbent. The accumulation of dust around the adsorbent will not only reduce the adsorption efficiency of the adsorbent on harmful substances in the air, but also may have an adverse effect on the physical and chemical properties of the adsorbent. In addition, the fixed filter design makes it difficult to replace and clean the filter, increasing maintenance costs and operational complexity;

[0005] 2. The adsorbent inside the filter is not fully utilized during use. Due to the difference in air flow, the air flow in the middle part of the adsorbent is larger, which makes the adsorbent in this area more likely to reach saturation, thus affecting the overall adsorption and filtration effect. At the same time, due to the smaller air flow at the edge of the adsorbent, its adsorption capacity cannot be fully utilized, resulting in reduced efficiency of the adsorbent. When the adsorbent in the middle is saturated, the filtration effect of the entire filter will be greatly reduced. The adsorbent at the edge is not used thoroughly. If it is replaced in advance, it will cause serious waste of adsorbent;

[0006] 3. When replacing the adsorbent inside the filter, the filter usually needs to be shut down due to the lack of effective filtering components, which will not only lead to a decrease in production efficiency, but may also have an adverse effect on the continuity and stability of the production line. In addition, shutting down to replace the adsorbent will increase the labor intensity and time cost of the operator, further reducing work efficiency. Summary of the invention
