Embodiment Construction

[0024] The filter medium is an M-shaped exhaust gas filter, comprising a base (1) and a filter body (17); the base (1) is provided with an exhaust gas inlet (2) and an exhaust gas outlet (13). Also includes M-shaped bracket (7). The device seat is the integral supporting part of the filter body, which is welded by channel steel and flat steel. According to the characteristics of the exhaust gas, the channel steel can be ordinary carbon steel or stainless steel, or a combination of the two. Standard profiles can be used, and steel plates can also be pressed. The M-shaped support (7) is installed inside the seat on the channel where exhaust gas flows from the exhaust gas inlet to the exhaust gas outlet; the filter body is attached to the working surfaces on both sides of each V-shaped mouth of the M-shaped support. As a flat medium, the filter body is folded into an M shape, which directly increases the interception area per unit space volume, improves the filtration efficiency...

Abstract

The invention relates to a waste gas filter with an M-shaped filtering medium. The waste gas filter is applied to treatment or recycling of organic waste gases or inorganic waste gases generated in spraying and painting processes of industrial manufacturing of furniture, automobiles, containers, shipbuilding and the like. The waste gas filter comprises a base and filters, wherein a waste gas inlet and a waste gas outlet are formed in the base. The waste gas filter is characterized by further comprising an M-shaped bracket; the M-shaped bracket is mounted on a channel through which a waste gas flows to the waste gas outlet from the waste gas inlet inside the base; the filters are adhered to working surfaces on two inner sides of each V-shaped hole of the M-shaped bracket. The waste gas filter has the advantages that the baffling area of unit volume of each filter is large, the filtering efficiency is improved, the size of a filter in the prior art is reduced, meanwhile, as the filters are arranged in the flowing direction of the waste gas, the energy loss of the flowing waste gas is reduced, the power of a fan is reduced, the filtration effect is stable, and the like.

Description

technical field [0001] The invention relates to an exhaust gas filter with an M-shaped filter medium, which is applied to the treatment or recovery of organic waste gas or inorganic waste gas produced by spray paint processes in industrial manufacturing such as furniture, automobiles, containers and shipbuilding. Background technique [0002] To use equipment to treat exhaust gas or to recover paint mist and VOCs from exhaust gas, it is necessary to perform coarse and fine filtration on the exhaust gas containing a large amount of impurities such as paint particles, dust and VOCs produced by spray booths or other pollution sources, and then to filter the exhaust in the exhaust gas. VOCs treatment is carried out by adsorption or elimination. [0003] Paint mist and dust not only interfere with the normal operation of treatment or recovery equipment, but also block the gaps between adsorbents, catalysts, and heat storage carriers, resulting in reduced treatment efficiency, and...
