Description
Technical field
The present invention relates to a kind of rotary-type dust arrester installation of explosion-proof bag, belongs to mechanical treatment process field.
Background technology
Being presently used for the bag collector of coal dust preparation system treating flour dust mainly has the explosion-proof bag collector of back-blowing, gas
The explosion-proof bag collector of case pulse and high-tension pulse spray explosion-proof bag collector.Yan Hemei is added to concentration of emission limit value because discharging new standard
The Optimal improvements of powder preparation technique, the explosion-proof bag collector of back-blowing is phased out, new production line and transformation project
Explosion-proof bag collector is sprayed using the explosion-proof bag collector of air box impulse or high-tension pulse.The explosion-proof bag collector of air box impulse is high pressure point
The explosion-proof bag collector of room off-line ash-clearing type, is widely used in the coal dust preparation system of cement, electric power, metallurgy industry.It is mainly tied
Structure and performance characteristics：1. outside filtering type is adopted, 1.0~1.2m/min of filtration velocity is designed, equipment steel consumption is relatively low；2. can process and be less than
1000g/m3High concentration dusty gas, as long as either still supporting all one-levels are gathered dust with air swept mill with vertical mill；3. using height
Pressure chamber off-line pulse dust cleaning, deashing pressure is 0.5~0.7MPa, and deashing kinetic energy is big, more thorough than back-blowing deashing.4. adopt
Inclined deflector has certain pre- dust collection effect as the pre- dust arrester installation of equal wind.5. explosion-proof locking-type decompression anti-explosion device is adopted,
Explosion-proof and sealing property is preferable.6. concentration of emission is less than 50mg/Nm3.High-tension pulse spray explosion-proof bag collector be also widely used in cement,
The coal dust preparation system of electric power, metallurgy industry.Its primary structure and performance characteristics：1. outside filtering type is adopted, filtration velocity 1.0 is designed
~1.2m/min, equipment steel consumption is relatively low；2. can process less than 1000g/m3High concentration dusty gas, only needs one-level to gather dust；3. adopt
Online ash removal is sprayed with high pressure row arteries and veins, deashing pressure is 0.5~0.7MPa, and deashing kinetic energy is big.4. it is pre- as equal wind using deflector
Dust arrester installation, there is certain pre- dust collection effect.5. Weight type decompression anti-explosion device is adopted, explosive-proof sealed performance is general.6. discharge
Concentration is less than 50mg/Nm3。
There is following defect in above two dust-precipitator：1. the filter bag selected be short bag, length typically in below 3250mm,
It is mostly between 2450~3050mm, does not give full play to arteries and veins and spray the advantage of deashing, and makes the floor space of equipment larger.2. adopt
With inclined deflector as the pre- dust arrester installation of equal wind, all dusty gases are by air inlet entrance, first Jing deflectors and flue
Air flow method is carried out by pocket bottom after stop, air-purifying chamber is entered back into Jing after sock filtration, can so cause dust-precipitator pocket
The interior gas rate of climb is excessive, the increase of the resistance of dust-precipitator, along with also increasing the pressure loss, gas tank using right-angle impulse valve
Between 1470~2000Pa, high-tension pulse spray explosion-proof bag gathers dust resistance of the explosion-proof bag collector of pulse when high-concentration waste gas are processed
Device is when high-concentration waste gas are processed typically between 1300~1800Pa.In addition, because of dusty gas from filter bag bottom by making
Into the abrasion at bag bottom, air flow method is uneven to also result in the uneven of filter bag abrasion, affects the service life of filter bag.3. two kinds
The decompression anti-explosion device that equipment is equipped with is that monolayer unloads laminated structure, there is that the difficult control of venting pressure, sealing property be bad, air leak rate of air curtain
High, sealing joint strip easily by door along cut it is bad, the problems such as original place, heat insulation effect difference can not be in time returned to after there is release.
The content of the invention
Present invention mainly solves technical problem：There is the difficult control of venting pressure for traditional bag collector, occurring
The problem of original place can not be in time returned to after release, the present invention is first detached air compression by air extractor, by front sieve
Net is isolated bulky grain thing, and the dust laden air with after Jing after isolation is compressed in main dust chamber, and Jing air-flows are rotated formula
Dust-precipitator is rotated, and the kinetic energy of High Voltage gas is converted into into energy needed for rotary dust-precipitator rotation, is subsequently gathered dust by rotation
Bag adsorbs layer by layer, and dust laden air is adsorbed and collected, then compressed in rear dust chamber, by the last mistake of pipeline screen cloth
Filter, adsorption particle Jing effect of inertia drops to time deashing chamber on screen cloth, while producing when the granule that rotary dust-precipitator is collected gathers dust
Raw omission granule, under gravity, by lower dust collection pipe main deashing chamber is settled down to.Explosion-proof bag of the present invention is rotary-type
After pressure release, dust collecting sleeve can in time return to original place to dust arrester installation, extend the service life of dust collecting sleeve, and dust collection rate reaches
More than 92%.
