Abstract
The invention discloses dust bag-type dusting technique under the unordered uneven state of one kind, the present invention replaces typical round or oval cloth bag by the design of fold filter bag, coordinate Special cage bone, sock filtration area is increased by more than 60%, while using big flow low frequency pulse valve jetting deashing technology, deashing pressure difference is improved to 1.2kPa, pulse frequency is reduced to 30 seconds/time, and deashing frequency is greatly reduced, and can effectively extend life of bag filter, operation maintenance number of times is reduced, cleaning efficiency is significantly improved.On this basis by the utilization of technology of Internet of things, the systems such as dust concentration measuring, cleaner start and stop, monitoring are realized into automation manipulation, human cost is reduced.
Description
Technical field
The present invention relates to dust bag-type dusting technique under dedusting technology field, more particularly to a kind of unordered uneven state.
Technical background
Domestic main flow dedusting technology includes electrostatic precipitation, bag-type dusting and electric bag combined dedusting at present.Removed from electrostatic
Dirt device（ESP）Since being applied to industry, a kind of generally acknowledged high effect dust cleaner is had evolved into, efficiency can reach more than 99%.
The advantage of electrostatic precipitation is that bulk density loss is small, and unit processing exhaust gas volumn is big, high temperature resistant, maintenance cost are low,
But major defect is efficiency of dust collection to be influenceed greatly by the physicochemical characteristics of flue gas and dust, for high resistivity dust, micro-
The dust removing effects such as thin and ultra tiny dust are undesirable.
Compared with electrostatic precipitator technology, China's bag type dust removing technology is started late, and the continuous improvement however as technology is entered
Step, the advantage of bag type dust removing technology is also more and more significant.The main advantage of sack cleaner be stable, strong adaptability,
Its efficiency of dust collection be little affected by processing air quantity change influence, can with filtering sub-micron level dust granules, not by gas and powder
The influence of dirt property, be easy to repair, to run power consumption low.So coal-burning power plant, the dirt source point in cement plant, garbage burning factory and
The fume treatment of steel plant, the overwhelming majority uses sack cleaner.
The content of the invention
It is an object of the invention to many drawbacks for overcoming prior art, there is provided dust bag under the unordered uneven state of one kind
Formula dust collecting process.In order to realize above-mentioned technical purpose, the present invention is adopted the following technical scheme that：
1. a kind of two way alternate formula grouting water technology for being used to administer roadway aproll, it is characterised in that dusty gas is by air intake
Mouth enters deduster, swash plate and baffle plate in the middle of inlet and outlet is initially struck, air-flow just turns to inflow ash bucket, while air velocity
Slow down, due to effect of inertia, crude particle dust in gas is flowed directly into ash bucket.Play a part of to gather dust in advance, into the gas of ash bucket
The outer surface of filter bag, purified gas are then rolled over and be trapped in upwardly through the internal filter bag dust equipped with metallic framework to stream
Into baghouse top clean room, air outlet discharge is pooled to,
During dusty gas is purified by filter bag, increase over time and the dust that is attached on filter bag of product is more and more,
Increase resistance of the filter bag, cause processing air quantity to gradually decrease, be normal work, to control resistance within the specific limits（140--170
The millimeter of water）, once deashing must be carried out to filter bag by overruning, and be opened during deashing by each control valve of pulse control instrument sequence trigger switch
The compressed air in pulse valve, gas bag is opened by each hole of injection tube through in Wen's pipe inspection to each corresponding filter bag, filter bag moment is anxious
Play expansion, makes product be attached to the dust releasing on filter bag surface, and filter bag restPoses.Dust lower clearly falls into ash bucket, through ash discharge system
System discharge body.Thus product is attached to dust on filter bag pulse jetting deashing periodically, make purification gas normal through, it is ensured that
Dust pelletizing system is run.
Brief description of the drawings
Fig. 1 is process chart of the invention.
Fig. 2 is sack cleaner schematic diagram.
Embodiment
The present invention has following significant advantage：
First, using big flow low frequency pulse valve jetting deashing technology, deashing pressure difference is improved to 1.2kPa, pulse frequency reduction
To 30 seconds/time, deashing frequency can be greatly reduced, cleaning efficiency is significantly improved.
Second, dedusting filtering bag designs for fold-type synthetic fibers filter bag, can increase filter area more than 60%, extends deashing
Interval, improves systematic entirety energy and life-span of the filter bag.
3rd, install sensor of dust concentration additional, built-in optical-electrical converter can fast and accurately show and export dust quality
Concentration, and according to setting concentration automatic start-stop deduster, convenient and swift remarkable in economical benefits.
Embodiment 1
Dusty gas enters deduster by air inlet, initially strikes swash plate and baffle plate in the middle of inlet and outlet, and air-flow just turns to stream
Enter ash bucket, while air velocity slows down, due to effect of inertia, crude particle dust in gas is flowed directly into ash bucket.Rise and gather dust in advance
Effect, the air-flow into ash bucket then rolls over and is trapped in filter bag upwardly through the internal filter bag dust equipped with metallic framework
Outer surface, purified gas enters baghouse top clean room, is pooled to air outlet discharge,
During dusty gas is purified by filter bag, increase over time and the dust that is attached on filter bag of product is more and more,
Increase resistance of the filter bag, cause processing air quantity to gradually decrease, be normal work, to control resistance within the specific limits（140--170
The millimeter of water）, once deashing must be carried out to filter bag by overruning, and be opened during deashing by each control valve of pulse control instrument sequence trigger switch
The compressed air in pulse valve, gas bag is opened by each hole of injection tube through in Wen's pipe inspection to each corresponding filter bag, filter bag moment is anxious
Play expansion, makes product be attached to the dust releasing on filter bag surface, and filter bag restPoses.Dust lower clearly falls into ash bucket, through ash discharge system
System discharge body.Thus product is attached to dust on filter bag pulse jetting deashing periodically, make purification gas normal through, it is ensured that
Dust pelletizing system is run.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to skill of the invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
