Gradual falling type gas multilayer dust filtering device

Abstract

The invention discloses a gradual falling type gas multilayer dust filtering device, and belongs to the field of dust filtering devices. The invention provides the gradual falling type gas multilayerdust filtering device, along with more and more smoke dust adsorbed on a gradual falling adsorption net, the gravity increase, the plurality of adsorption fixed balls can be gradually torn open, so that a gradually falling adsorption net gradually moves downwards, on the one hand, the gradual falling adsorption net moving downwards can enter a dust washing solution, so that dust is desorbed, and repeated use of the gradual falling adsorption net is facilitated; and on the other hand, the gradual falling adsorption net with a folded upper part is gradually unfolded, so that the intact gradual falling adsorption net can further adsorb smoke dust particles, the dust filtering device can be effectively guaranteed to continuously keep a good adsorption effect for flue gas adsorption, the adsorption efficiency of the device is effectively improved, and compared with manual replacement of a filter screen in the prior art, the device can achieve position change of the gradual falling adsorption net independently along with the increase of the smoke dust adsorption amount in the use process, and the flue gas adsorption efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of dust filtering devices, in particular to a gradual-fall gas multi-layer dust filtering device. Background technique [0002] Smoke is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes SO2, CO, CO2, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10 microns, especially the 1-2.5 micron floating dust is the most harmful. The air pollution of smoke and dust is closely related to meteorological conditions. , Atmospheric stability, turbulence, etc. are closely relat...

Problems solved by technology

[0003] Based on the flue gas released in industrial production, especially in some industrial plants, the flue gas contains a large amount of oily dust, which needs to be adsorbed before being discharged. However, the filter used in the prior art for the adsorption of oily dust in the flue gas Due to the large amount of flue gas, the frequency of filter replacement, maintenance and cleaning is relatively high, which affects the efficiency of the entire flue gas emission
