Prefinished combined pleated membrane air filter

Abstract

The invention discloses a pre-finishing combined folded membrane air filter, which comprises an upper casing, a pressure gauge on the top of the upper casing, a lower casing and a leg at the bottom of the lower casing, and a medium-efficiency filter element is arranged in the upper casing And the high-efficiency filter element, the high-efficiency filter element is nested in the medium-efficiency filter element; the lower end of the medium-efficiency filter element is connected to the connection base between the upper shell and the lower shell; the upper end of the high-efficiency filter element is connected to the fixed pressure plate, and the lower end is connected to the lower shell The upper fixed tube plate is connected, and the fixed pressure plate and the fixed tube plate are connected by a support rod; an air intake pipe is arranged on one side of the upper shell, and a windshield is set on the side of the medium-efficiency filter element corresponding to the air intake pipe, and the upper shell An upper exhaust valve is provided on the other side of the upper casing, and a deflector is arranged at the lower part of the inner side of the upper casing corresponding to the upper exhaust valve; an exhaust pipe is arranged on one side of the lower casing, and a detection valve is arranged on the exhaust pipe. A lower exhaust valve is provided at the bottom of the lower case. The invention has the advantages of compact structure, convenient operation and high filtration efficiency.

Description

technical field [0001] The invention belongs to an air filter, in particular to a pre-finishing combined folded membrane air filter. Background technique [0002] Air filters are needed to provide sterile air in industries such as bioengineering, electronics, and biofermentation. At present, in the domestic air filter market, split-type pleated membrane filters account for more than 90% of the entire market, but in the process of using this type of filter, its disadvantages are becoming increasingly apparent. For example, the structural design of this kind of filter is unreasonable, the medium-efficiency filter cannot be sterilized, and the equipment occupies a large space. The above-mentioned shortcoming has caused serious waste to the user in terms of energy, resources, manpower, etc., and has greatly increased the possibility of bacterial contamination.
