Dynamically adjustable waste gas filter

Abstract

The invention discloses a dynamically adjustable waste gas filter which comprises a box body, a gas inlet and a gas inlet pipe which are positioned on the lower side of the box body, and a gas outlet and a gas outlet pipe which are positioned on the upper side of the box body, a cavity is formed in the wall of the box body, a rotary filter belt is arranged in the cavity in a penetrating manner, and the part, covering the gas inlet and the gas outlet, of the rotary filter belt plays a role in filtering waste gas; an adjusting part for adjusting the stretching form of the filter belt is arranged near the gas inlet; one side wall of the box body is also provided with a hollow part communicated with the cavity, and the hollow part is provided with a cleaning part for cleaning the filter belt. According to the rotary filter belt, the service life of the filter belt is prolonged, frequent manual replacement of the filter belt is avoided, the filtering efficiency of the whole filter is improved, the adjusting part dynamically adjusts the density of the filter screen according to the waste gas dirt content, the waste gas filtering effect is enhanced, the cleaning part timely removes dirt on the filter belt, and the stable filtering effect of the filter belt can be kept for a long time.

Description

technical field [0001] The invention relates to the fields of environmental protection and waste gas treatment, in particular to a dynamically adjustable waste gas filter. Background technique [0002] Waste gas treatment refers to the treatment of adsorption, filtration and purification of waste gas generated in the process of industrial production. The traditional dry filter is only equipped with a filter at the exhaust gas inlet. After absorbing dust and other impurities, it needs to be disassembled, cleaned and replaced repeatedly. The operation is inconvenient, so that the filtering effect of the exhaust gas cannot be guaranteed. The entire filter The filtration efficiency is also relatively low, and the existing dry filters cannot be dynamically adjusted according to the exhaust gas conditions, and cannot filter the exhaust gas more thoroughly. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a dynam...
