Description

TECHNICAL FIELD

[0001] The utility model relates to cold storage transportation technical field especially sewage pump station ventilation device. BACKGROUND

[0002] As a key link of urban sewage collection and transportation system, the normal operation of sewage pump station is of great significance to guarantee the efficiency of urban sewage treatment and environmental quality. During the operation of sewage pump station, the ventilation device plays a crucial role. The main function of the existing sewage pump station ventilation device is to realize the replacement of air to ensure the air quality inside the pump station and provide a relatively comfortable environment for equipment operation and personnel work. However, these ventilation devices have some problems to be solved in practical application.

[0003] On the one hand, when the ventilation device ventilates, it cannot preliminarily filter the inhaled air. This means that dust, particulate matter, microorganisms and other impurities in the air will directly enter the internal space of the pump station. These impurities may have adverse effects on the equipment inside the pump station, such as adhering to the surface of the equipment, affecting the heat dissipation and normal operation of the equipment, and reducing the service life of the equipment; they may also accumulate inside the pump station, increasing the workload and difficulty of cleaning and maintenance. In addition, the entry of impurities may also have a negative impact on the air quality inside the pump station, affecting the health of the workers. On the other hand, when the exhaust is performed, the existing ventilation device cannot filter the contaminated gas to meet the emission standards. Sewage pump stations produce various contaminated gases during operation, such as hydrogen sulfide, ammonia and other gases with irritating odor and harmful components. If these contaminated gases are directly discharged into the atmosphere without effective filtration, they will cause serious pollution to the surrounding environment and affect the quality of life and ecological environment of the surrounding residents. Although some ventilation devices may be equipped with some simple filtering devices, the filtering effect is not complete, and a part of the contaminated gas can still escape into the atmosphere, which cannot meet the increasingly strict environmental emission requirements. Therefore, a ventilation device capable of effectively filtering gas during exhaust is needed. SUMMARY
