Description

Technical Field

[0001] The utility model is applied to the technical field of deodorization, and particularly relates to a deodorization system for a garbage transfer station. Background Art

[0002] With the rapid development of urban construction, the contradiction in the disposal of urban garbage has become increasingly prominent. The construction of garbage transfer stations is not only conducive to the centralized, unified, standardized and harmless treatment of garbage, but also helps to improve the dirty, messy and poor environmental status, and at the same time meets the improvement of people's living environment level. However, the daily operation of existing garbage transfer stations will inevitably have a certain impact on the surrounding environment. The main impact is the environmental impact caused by the leakage of malodorous gases generated by garbage into the surrounding environment. The malodorous gases generated by garbage storage mainly include ammonia, hydrogen sulfide, aliphatic substances such as methanethiol and trimethylamine, and its components are relatively complex. How to take effective measures to treat malodorous gases is a problem that every garbage transfer station needs to consider. For example, the Chinese patent with the publication number CN111589280A discloses a wall-mounted deodorization device for a garbage transfer station, which adopts a wall-mounted structure to ensure the effective space for garbage treatment in the garbage transfer station; the plasma discharge disk is inclined obliquely downward from front to back, which achieves the purpose of deodorization to a certain extent, but it is difficult to completely eradicate the effective gas and can only achieve one-sided deodorization. The existing technology has limitations in aspects such as low treatment efficiency, high energy consumption and difficulty in meeting strict emission standards. Therefore, it is necessary to provide a deodorization system for a garbage transfer station that can effectively and comprehensively degrade and eliminate malodorous pollutants and significantly enhance the overall purification effect. Summary of the Utility Model

The second ion ventilator is located on the left side of the waste transfer workshop, and the negative pressure air collection hood is located on the right side of the waste transfer workshop.

[0011] One preferred solution is that the odor removal system of the waste transfer station further includes an odor removal chemical tank and a chemical dosing pump.
