A high-efficiency air filtration and dehumidification device

Abstract

The invention relates to an efficient air filtration and dehumidification device. The device comprises a rotating filtration module used for removing large liquid droplets, and an inertial impaction filtration module used for removing submicron liquid droplets. The rotating filtration module I successively comprises, from the windward side inwards, a blade-type cyclone air-distributing pipe, a contracting-type centrifuge pipe and an inserted-type flow equalizing outlet. The inertial impaction filtration module comprises a gradually-expanding-type deceleration flow equalizing pipe, an inertial impaction separating plate and an air flow outlet. Both the contracting-type centrifuge pipe and the inertial impaction separating plate are provided with a water collecting and discharging pipe at the bottom. According to the invention, dimensional proportions of each part are calculated and determined by a computational fluid dynamics technology, thus ensuring that a filtration module has advantages of reasonable structure, small size and structure resistance changes, long service lifetime, no water accumulation and no need of maintenance. The device provided by the invention has a compact structure. The device can be specially used for air filtration systems that are frequently exposed to a high-humidity environment, and can be used as a pre-filtration structure for other air filtration devices.

Description

technical field [0001] The invention belongs to the technical field of air filtration, and in particular relates to a high-efficiency air filtration and dehumidification device, which is specially designed to provide an air pre-filtration and dehumidification module with anti-droplet and low resistance for air conditioning systems often in high-humidity environments. Background technique [0002] The air filters used by existing means of transportation (comprising railway trains, automobiles, and ships) are divided according to the filter structure, and are mainly divided into three categories: clapboard foldable type, no divider foldable type, and cylindrical type. Due to the low filtration efficiency of metal mesh filter element, it has tended to be eliminated in vehicles such as automobiles. Since the 1960s, a new type of pleated paper filter element has appeared. After continuous improvement in technology, it has high filtration efficiency of 95% to 99%, low cost, conven...

Problems solved by technology

However, the structure of the filter used by vehicles in the domestic market generally has the following disadvantages: first, the rainproof performance is extremely poor, and it is easy to cause filter blockage in a high-humidity environment; , the dust holding distribution is unreasonable, and the resistance of large particles on the fiber filter material increases relatively quickly, which reduces the service life of the filter; the third is low mechanical strength and poor mildew resistance
