At present, the smoke gas treatment difficulty of high temperature high humidity occasions such as the cement in vertical kiln in cement plant, dryer is very big.The high-efficiency dust remover that is fit to these class industrial and mining enterprises of China, the effect that the glass fiber bag type deduster uses is relatively good.This class deduster roughly is divided into two kinds: a kind of is to adopt top air intake, following air-out mode, and the upper face plate dust stratification is serious, complicated integral structure.When ambient temperature was low, the cold air of reverse gas cleaning suction contacted with the hot flue gas in the dirt air chamber, very easily causes dewfall on deduster, filter bag surface, causes filter bag to stick with paste bag, influences the operate as normal of deduster, shortens the service life of filter bag.Simultaneously, when cold and hot gas contacts, also can cause the shell plates dewfall, cause the housing corrosion, the service life of reducing equipment.Another kind is to adopt bottom air intake mode, and this equipment blast pipe is positioned at enclosure interior, causes overhauling difficulty and strengthens, and equipment occupation space also increases.This equipment still adopts the atmosphere reverse gas cleaning, and the dewfall that deashing causes also fails to solve, and the deashing control of this equipment is adopted and promoted transfer valve, in the valve plate course of action, the blowback air-flow with discharge air-flow the opening time long the time arranged, influenced ash-removal effect.These two kinds of dedusters arrive deduster inside at flue gas can not evenly enter each filter bag with flue gas, and it is worn out to cause the part filter bag to take place because of local air flow speed is high.These two kinds of dedusters all adopt the box frame formula, and its complex structure, floor space are big, and the steel consumption is high.
The utility model content
For worn out, complex structure, the steel that overcomes that dewfall, flue gas that existing glass fiber bag type deduster causes at deashing can not enter evenly that each filter bag causes that the part filter bag takes place because of local air flow speed is high consumes high deficiency.The utility model provides a kind of glass fiber bag type deduster, and this deduster does not only cause dewfall when deashing, and flue gas evenly enters each filter bag elimination part filter bag because of high take place worn out of local air flow speed.Simultaneously, this deduster is simple and compact for structure, and floor space is little, and the steel consumption is low.
The technical scheme that its technical problem that solves the utility model adopts is: contain housing, filter bag, upper face plate, lower face plate, three-way switch valve, exhaust duct, reverse-blow pipe, ash bucket, cross over pipe, ash-valve, upper face plate and lower face plate are separately positioned on housing internal upper part and bottom, be provided with filter bag between upper face plate and the lower face plate, lower housing portion is provided with ash bucket, case top is equipped with exhaust duct, reverse-blow pipe, cross over pipe and three-way switch valve, reverse-blow pipe and back blowing machine outlet link, also contain deflection cone, the center blast pipe, housing is columnar structured, upper face plate and lower face plate that the center blast pipe is arranged on the center of top of housing and passes enclosure interior enter in the ash bucket, deflection cone is set in the below of center blast pipe and above the center of ash bucket, the arm of back blowing machine import and exhaust duct links.
At least be divided into four locellus in the housing.
Ash bucket is a conical structure.
The beneficial effects of the utility model are, housing adopts columnar structured, make simple and compact for structurely, and area occupied is little, and the steel consumption is low; Enter in the ash bucket and the below of center blast pipe is provided with deflection cone because the center blast pipe is arranged on the center of top of cylindrical shell and passes enclosure interior, when high-temperature flue gas enters ash bucket by the center blast pipe, can evenly enter each filter bag of deduster through blocking of deflection cone, Mars bulky grains etc. are because effect of inertia directly falls into ash bucket, avoided the Mars bulky grain directly to contact, caused filter bag to burn out with filtrate.Simultaneously since high-temperature flue gas through the blocking of deflection cone, wind speed is slower, has also avoided filter bag because of high take place worn out of local air flow speed.Because the clean hot gas of the secondary that exhaust duct is discharged carries out reverse gas cleaning by its arm by back blowing machine and reverse-blow pipe, has effectively prevented the dewfall in the deduster.Because dusty gas from bottom to top enters exhaust duct by upper face plate again through lower face plate and filter bag, the clean hot gas of secondary enters locellus by reverse-blow pipe through upper face plate and carries out deashing in the process of deashing.Thereby do not have dust stratification on the upper face plate, and both be convenient to safeguard, reduced the deduster load again.
