Circulating self-cleaning type primary-effect air purification device for subway machine room combined air conditioning cabinet

Abstract

The invention discloses a circulating self-cleaning type primary-effect air purification device for a subway machine room combined air conditioning cabinet, and relates to the field of air purification devices. The air purification device comprises a main framework, wherein a driving mounting base is fixedly connected to the upper surface of the front of the main framework, the main framework is fixed to a driving-driven servo drive assembly through the drive mounting base, a guide tensioning shaft is arranged in the middle of the main framework in the vertical direction, a filter material isarranged in the middle of the interior of the main framework, and the filter material is arranged on the main framework by a certain folding angle through the driving-driven servo drive assembly and the guide tensioning shaft. According to the air purification device, inhalable particles in subway return air and fresh air can be effectively purified and treated, the requirements for the purification efficiency and the wind resistance of a subway air conditioning system are met, and the effects of being safe and reliable are achieved; meanwhile, the device is provided with a reciprocating self-cleaning high-negative-pressure dust suction device, so that the purification device has a self-cleaning function; and the filter material is repeatedly used in a certain resistance range after self-cleaning, so that the later operation cost is reduced.

Description

technical field [0001] The invention relates to the field of air purification devices, in particular to a circulating self-cleaning primary-effect air purification device for a combined air-conditioning box in a subway machine room. Background technique [0002] As a green and low-carbon transportation mode, rail transit has the advantages of large capacity, high safety and reliability. Public areas such as subway platforms, station halls, and transfer passages are places where passengers and staff stay. The quality of their air quality affects the health of many people. At present, the concentration of major particulate pollutants in the subway environment accounts for more than 80%, and the air quality is poor; because the central air-conditioning ventilation system has the risk of spreading diseases, and the concentration of indoor respirable particulate matter increases, the damage is even more difficult to reverse after it is formed. It has been confirmed that bacteria...

Problems solved by technology

[0003] At present, there are two types of air purification devices used in subway stations: one is a simple filter device installed in an empty box, which cannot adapt to the high content of inhalable particulate matter in the return air in the subway, and must be cleaned in a short time Or replace the filter material, and the purification efficiency is seriously reduced after cleaning, and the cost is too high due to frequent replacement; the other type is the air purification equipment for the subway air duct, which can only purify the fresh air or return air of the subway, and the equipment investment cost is high. The equipment occupies a large space, the filtering effect is poor, and the maintenance cost is high
