Deduster airduct intelligent spray settlement device

Abstract

The invention discloses a deduster airduct intelligent spray settlement device. The device comprises a dust collection airduct, branch pipes intensively connected to an inlet of the dust collection airduct and a bag filter connected to an outlet of the dust collection airduct. The device also comprises an intelligent controller, a dust concentration detector and a spray settlement chamber connected to the middle of the dust collection airduct. A flow baffle is medially arranged in the spray settlement chamber. A flow baffle settlement chamber is medially arranged at the top in the spray settlement chamber. A flow baffle is medially arranged in the flow baffle settlement chamber. A funnel-shaped upper air flue and a funnel-shaped lower air flue communicated with the spray settlement chamber are symmetrically arranged on the flow baffle settlement chamber bottom at left and right sides of the flow baffle as a symmetric center and extend downward. The top of the spray settlement chamber is provided with a spray device connected to a water pool. The device is designed according to a gravity settlement principle, adopts an automatically adjustable spray device, solves the problems of excess internal dust, overlarge deduster load, non-ideal dedusting effects and explosion easiness, is safe, energy saving and environmentally friendly, can be operated simply, and has a low equipment investment cost.

Description

technical field [0001] The invention relates to the technical field of wood dust recovery devices, in particular to an intelligent spray settlement device for air ducts of dust collectors. Background technique [0002] A large amount of wood dust will be generated in the production process of wood processing enterprises, and wood dust is a flammable organic dust. The mass of the monomer is small and easy to diffuse in the air. A large amount of wood dust accumulated in full contact with the air will explode in a confined space. The concentration limit, dust explosion is very easy to occur when encountering an ignition source. As a flammable and explosive hazard source, wood dust has seriously threatened the safe operation of wood processing enterprises. [0003] In order to solve the above problems, existing wood processing enterprises generally use bag filter to remove dust from wood dust, which has achieved certain results.

AI Technical Summary

Problems solved by technology

[0004] Reference attached figure 2 , this figure shows the structure of a common bag filter air duct in the prior art. The dusty gas in each branch pipe 15 is directly collected and concentrated through the dust collection air duct 3 and enters the bag filter 8, while wood processing The uniqueness of the enterprise determines that the bag filter 8 cannot fully meet the existing dust removal requirements for a long time. Generally, the wood dust production in wood processing plants changes with the working conditions, and the dust concentration varies in a wide range. The dust collection duct 3 and the bag filter 8 The internal dust concentration is sometimes low and sometimes high, especially when the dust concentration is high, the load of the bag filter 8 is too large, the dust removal effect is not ideal, it is easy to cause the dust concentration to reach the dust explosion concentration limit, and there is also the risk of dust explosion

[0005] The existing gravity settling chamber can also be used as a dust removal device to a certain extent by using the principle of gravity settling, which can generally remove particles with a large monomer mass, but for wood dust, its monomer mass is small and it is easy to diffuse in the air. The gravity settling chamber is difficult to settle the wood dust in a large scale
