Technical Field
[0001] The utility model relates to the technical field of indoor air purification, in particular to a double-circulation air purification system for indoor purification. Background Art
[0002] There are often staff activities in the garbage disposal room of the garbage disposal station. Various waste gases are mixed indoors, and the odor is heavy, which is not good for the physical and mental health of the staff. In order to maintain the health of the staff, it is necessary to purify the indoor air. In the prior art, the circulation treatment method for this kind of fixed waste gas pollution is generally to exchange indoor and outdoor air through forced external circulation, so that fresh air can continuously enter the room to improve the indoor air quality and reduce the odor. However, direct external circulation pollutes the air around the outdoor environment, which is not friendly to the environment and has a great impact on the daily life of the surrounding residents. There are also purification devices that purify the indoor air through continuous internal circulation to remove the odor and harmful gases of indoor waste gas. However, for large enclosed spaces with high waste gas content and heavy odor such as odor, it is not enough to rely solely on the internal circulation treatment of the purification device. If the number of purification devices invested is increased to achieve the purification effect, the operating cost of the equipment investment will increase, the economic benefit is poor, and it is difficult to ensure the long-term and lasting operation of the garbage disposal system.
[0003] Therefore, it is necessary to design an indoor air purification treatment system for the air in the garbage treatment room that can operate continuously with high efficiency and low consumption to ensure its long-term operation. Utility Model Content
