Description
Technical field
The utility model belongs to industrial dedusting apparatus field, is related to a kind of air box impulse deashing for micropore film dust-remover
System.
Background technique
In recent years, as industrialization aggravates, vehicle guaranteeding organic quantity increases, the quickening of urban construction paces, and urban air is dirty
Dye problem rapidly becomes the focus of people.China is increasingly stringenter the emission request of pollutant at present, such as ecological, environmental protective portion
In May, 2018 requires all production works of iron and steel enterprise in " iron and steel enterprise's minimum discharge retrofit work scheme (exposure draft) "
Sequence (iron content ore mining choosing, stock yard, sintering, pelletizing, coking, ironmaking, steel-making, steel rolling etc. and bulk material Product transport) should all
Reach 10mg/m3Minimum discharge it is horizontal.And can the quality of deashing be directly related to deduster and well run, it is therefore desirable to
Dust pelletizing system deashing property is created and is transformed, to meet national requirements.
The filter bag of conventional bag deduster is using weaving filter cloth or non-woven felt, and shape is divided into flat bag or round bag
Filter bag filtrate is using cotton fiber, wool fibre, synthetic fibers and glass fibre etc., although the filter bag of traditional sack cleaner can
With guarantee it is granular material discharged reach standard, but because of mine particulate matter water content height, commonly there is moisture condensation, viscous in filter bag in use
Bag, phenomena such as deashing is difficult, cause that life of bag filter is short, live dust sucting point is difficult to ensure dust suction requirement.In order to cause the device to
Meet high humidity environment dust removal requirement, filtrate is improved, the core filtering material using microporous barrier as equipment, micropore
Film filtering material hydrophobicity is good, porosity is high, intensity is big, long service life and installation and replacement are very convenient.Based on this, mine system
Using advanced microporous barrier dust-extraction unit.
Currently, mine system using microporous barrier dust-extraction unit purge mode or mechanical vibrator by the way of, work as micropore
Film surface dust accumulation is fallen off, high frequency vibration dust-cleaning is endless to certain thickness by the time-controlled high frequency electric motor of shaker rapping of PLC
It is apt to and is damaged to a certain extent filtrate influence its service life, deashing is not thorough, is insufficient for high wet dust, according to mesh
Before " iron and steel enterprise's minimum discharge retrofit work scheme (exposure draft) " standard, it is difficult to meet the horizontal 10mg/ of minimum discharge
m3Emission request.In addition, if run under the premise of so that it is met high-efficiency low-resistance, and broader industrial circle is adapted to,
Also need deeper into research, and other purge mode has reverse gas cleaning mode, and this purge mode uses woven cloth mostly
The viscous class filtrate of filtering can also be used for the dust for being easier to fall clearly in filtrate such as 729 filter clothes.Reverse gas cleaning mode is more clear than vibrating
Grey mode wants small to the damaging action of filter cloth, but the effect of its deashing is weaker；For pulse jetting deashing mode, in its deashing
In a flash, when high speed jet-stream wind passes through filter bag top, it can induce the air times over injection tolerance, blow to filtrate together
Inside forms air wave, and filtrate is made to generate expansion and impact vibration sharply from top to bottom, generates the work of very strong clear powder falling dirt
With.Pulse period is adjustable, and generally 1 minute to a few minutes.Pulse dust cleaning effect is stronger, and ash-removal effect is preferable, can be improved
Filtration velocity.Its intensity and frequency be all it is adjustable, can equally obtain good deashing using preferable blowing device
Effect.For the design feature of excellent micropore film filtering material itself, the filtrate of production is mostly framework, the blowing of action of low-voltage pulse nozzle
The method of deashing is not appropriate for, and air box impulse ash removal method is relatively suitble to this structure.Air-tank type pulse dust collector deashing device
Injection tube and injector are not set, structure is simple, convenient for changing bag；Pulse valve quantity is few, and maintenance load is small.
The utility model patent of Chinese Patent Application No. 201720022989.5 discloses a kind of applied to efficiently damp proof super
The soot cleaning system of net deduster, the utility model rinse filter by three kinds of deashing device action of low-voltage pulse blowings, mechanical vibrator and water
The combination of film carries out deashing, realizes the purge mode for being suitable for efficient damp proof ultra-purifying dust collector, solves mine dedusting
Problem.Structure is complicated for the deduster, and operating process is cumbersome and to expend capital larger, although can be good at solving the problems, such as,
But the problem for causing cost too big does not account for.
The utility model patent of Chinese Patent Application No. 201510752861.X discloses a kind of for the micro- of high humidity environment
Composite filtering film is covered on board-like filter element by the filtrate component constituted by hole film dust-remover, the utility model patent
On, have filter area big, occupied area is saved, the characteristics of high dust collection efficiency；Composite filtering film water repellency is good, realizes and removes
Requirement of the dirt device in high humidity dust pelletizing system environment.The deduster uses mechanical rapping cleaning dust, causes deashing halfway
Problem, for a long time in this way, causing ash-removal effect poor, efficiency of dust collection is low, is difficult to meet national relevant particles object discharge standard.
Chinese Patent Application No. is that the utility model patent of 201410082161.X discloses plate and frame PTFE film deduster,
The utility model patent is by being applied to plate and frame module for PTFE microporous membrane material, and with high dust collection efficiency, deashing is easy,
The advantages that corrosion-resistant, high temperature resistant, the cycle of operation is long, and filter area is big and treating capacity is big.But the utility model patent only mentions
Go out plate and frame PTFE film to apply in deduster, is not discussed in detail the method for operation for introducing removing dust and clearing ash system, it is right
Guidance is not played the role of in the research of the soot cleaning system of micropore film dust-remover, proposes one kind based on this utility model patent
Air box impulse soot cleaning system for micropore film dust-remover.
