Abstract

The utility model relates to an air filter, belonging to the field of air filtering devices and comprising a box body, and a filtering area and a cleaning area which are arranged in the box body. The space in the box body is divided into a gas settling area, the filtering area and the cleaning area by a vertical partition plate, and the gas settling area, the filtering area and the cleaning area are sequentially communicated; an air inlet is arranged at the front of the gas settling area; an air outlet is arranged at the rear of a cleaning chamber; a filter cylinder in the filtering area is transversely installed on the partition plate; a plurality of nozzles are fixed on a supporting frame in the cleaning area corresponding to the filter cylinder opening; each nozzle is connected with an air bag through a pipeline; and the supporting frame is welded at the upper end and the lower end of the box body. With the transverse installation of the filter cylinder of the filtering area, the nozzles of the cleaning area are utilized to complete back blowing, so that the utility model not only has good filtering effect and strong back blowing cleaning force, but also has small occupied area, convenient maintenance and long service life.

Description

Air cleaner

Technical field

The utility model belongs to the air filter field, refers in particular to the air cleaner of a kind of use in gas handling systems such as gas engine, air compressor machine, blast furnace air, diesel engine, clean room air feed.

Background technology

Use is at the air cleaner of gas handling systems such as gas engine, air compressor machine, blast furnace air, diesel engine, clean room air feed, usually, the space is made up of the clean dead zone at top, middle filtering area, the filter screen district of bottom in the envelope of equipment, the deficiency that exists is: 1, because air cleaner is installed in outdoor, rainwater is easy to enter the bottom screen district, and it is wet impaired that part of appliance is subjected to; 2, the filter cylinder in the filtering area is lifted on the horizontal baffle, and vertically arranged filter cylinder has brought inconvenience to maintenance, and the people can only bend over to climb in filtering area to finish the work, and filter cylinder is changed quite trouble; 3, a filter cylinder mouth correspondence is provided with a Venturi tube in the toilet, and all Venturi tubes insert a gas transmission main and connect gas bag, has only a pipeline to connect gas transmission main by gas bag, and the gas strength that enters each Venturi tube is less, and effect is undesirable during blowback.In addition, Venturi tube is fixed on the dividing plate to be needed by screw and holdfast, and there is screw the toilet, and purge gas vibrations screw just can produce loosening, and gas enters gas engine, air compressor machine, blast furnace air, diesel engine, thereby destruction equipment can't operate as normal; 4, after blowback, the dust of cartridge filter falls within ground behind the filter screen district, can't collect, and enters the filter core appearance repeatedly, increases the filter core burden, and these dusts still can enter air cleaner, have had a strong impact on filter effect.

Summary of the invention

The present invention is just in order to overcome above-mentioned deficiency, a kind of good filtration effect, convenient, the cleaner air cleaner of backwash of maintenance are provided, main innovation is that filter vertically is divided into three zones (gas decanting zone, filtering area, clean area) gas connection successively by dividing plate, filter cylinder in the filtering area is horizontally installed on the dividing plate, corresponding each filter cylinder mouth is provided with nozzle pipe and is communicated with gas bag and carries out blowback in the toilet, great efforts, clean power is strong, and the support two ends of fixing each nozzle are welded in the top and the bottom of casing, guaranteed that the toilet does not have screw, good seal performance.Specifically implement like this: air cleaner, comprise casing, filtering area and clean area in the casing, it is characterized in that the interior space of casing is separated into gas decanting zone, filtering area and the clean area of gas connection successively by vertical partition plate, gas is equipped with air inlet before the decanting zone, be equipped with the gas outlet behind the toilet, filter cylinder in the filtering area is horizontally installed on the dividing plate, the corresponding plurality of nozzles that is fixed on the support that is equipped with the filter cylinder mouth in the clean area, described each nozzle pipeline respectively connects gas bag, and described support is welded in the casing upper and lower side.When needing repairing after the long-time use of air cleaner, the people only need stand in dismounting filter cylinder in the gas expansion chamber, and is convenient light again.

The utility model is provided with dust bucket below filtering area and gas decanting zone, the dust that falls is collected processing, and can not have an opportunity to enter filter influences filter effect.

Be provided with demister before the air inlet on the gas of the present utility model decanting zone, avoiding in the rainwater access arrangement, prolonged filter core service life.

The utility model is laterally installed the filtering area filter cylinder, utilizes the clean area nozzle to finish blowback, good filtration effect not only, and the clean power of blowback is strong, and the entire equipment floor space is little, and maintenance is convenient, long service life.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Air cleaner, comprise casing 1, the space is separated into the gas decanting zone 3 of gas connection successively by vertical partition plate 2 in the casing, filtering area 4 and clean area 5, be equipped with air inlet 6 before the gas decanting zone 3, be provided with demister 7 before the air inlet 6, be equipped with gas outlet 13 behind the toilet 5, filter cylinder 8 in the filtering area 4 is horizontally installed on the dividing plate, the corresponding plurality of nozzles 10 that is fixed on the support 9 that is equipped with the filter cylinder mouth in the clean area, described each nozzle 10 pipeline respectively connects gas bag 11, described support 9 is welded in the casing upper and lower side, and filtering area 4 and 5 belows, gas decanting zone are provided with dust bucket 12.

Claims (3)

1. air cleaner, comprise casing, filtering area and clean area in the casing, it is characterized in that space in the casing is separated into gas decanting zone, filtering area and the clean area that gas successively is communicated with by vertical partition plate, gas is equipped with air inlet before the decanting zone, is equipped with the gas outlet behind the toilet, filter cylinder in the filtering area is horizontally installed on the dividing plate, the corresponding plurality of nozzles that is fixed on the support that is equipped with the filter cylinder mouth in the clean area, described each nozzle pipeline respectively connects gas bag, and described support is welded in the casing upper and lower side.

2. air cleaner according to claim 1 is characterized in that filtering area and gas decanting zone below is provided with dust bucket.
