Description
Technical field
The utility model is related to a kind of band dusty gas dust removal by filtration device.
Background technology
Particulate matter is removed from dusty gas to reduce the technical measures that it is discharged to air.Dust-laden industrial waste gas or generation
In mechanical processes such as the crushing of solid matter, screening, conveying, explosions, or result from burning, high-temperature fusion and chemical reaction and waited
Journey.The former contains big granularity, chemical composition and former solid matter identical dust, and the latter contains small granularity, chemical property and life
There is other flue dust into its material.Particularly gases at high pressure (gas such as nitrogen or carbon dioxide), and being unloaded in decompression process
Carrying dust in deflation secretly causes line clogging, valve wear and high-decibel noise problem.
For problem above, traditional deduster is widely used in the dust and flue dust that control has been produced.Can by trapping mechanism
It is divided into mechanical dust collector, electric cleaner, filter collector and scrubber etc..Mechanical dust collector by mechanical force by grit from
Removed in air-flow, its is simple in construction, and installation cost and running cost are relatively low, but efficiency of dust collection is not high；Electric cleaner utilizes electrostatic force
Realize that grit is separated with air-flow, often classify by board-like with tubular type, feature is that gas-flow resistance is small, efficiency of dust collection up to more than 99%,
But it is larger to invest higher, floor space；Filter collector makes dust-contained airflow by filtrate by grit separation and collection, point self-filtering
With surface filtration two ways, efficiency of dust collection is generally 90%~99%, is not suitable for the high dusty gas of temperature；Cleaning dust
Device washes dusty gas by liquid, grit is collided and is captured with drop or liquid film, and is separated with air-flow, and efficiency of dust collection is
80%~95%, running expense is higher.
The content of the invention
To overcome disadvantages mentioned above, it is low that the purpose of this utility model is to provide a kind of simple in construction, cost, small volume, operation
Cycle is long, the high band dusty gas dust removal by filtration device of efficiency of dust collection.
To achieve the above object, a kind of band dusty gas dust removal by filtration device of the present utility model, it includes filtration barrel body,
Whirlwind barrel, dusty gas entrance, fine powder discharge gate, gas inlet and outlet, it is characterised in that the top of filtration barrel body has gas to enter
Outlet, the bottom of filtration barrel body connects the upper end of Whirlwind barrel, has filter in filtration barrel body, filter bottom end has baffle plate,
Filter top end is communicated with gas inlet and outlet, and annular reverse taper, the lower end connection of annular reverse taper are arranged at the top in Whirlwind barrel
Whirlwind riser, the lower end connection whirlwind reverse taper of Whirlwind barrel, whirlwind reverse taper lower end connection fine powder discharge gate, in cyclone cylinder
Dusty gas entrance is arranged at the top of body.
Dusty gas entrance as described above is in tangent line with Whirlwind barrel inwall.
Filter as described above is by screen pack, filter screen spoke fixing collar and filter screen spoke composition, filter screen spoke fixing collar
Vertical with filter screen spoke to be connected, screen pack is connected with filter screen spoke.
The small aperture of screen pack as described above is less than or equal to dust average grain diameter.
A kind of application with dusty gas dust removal by filtration device of the utility model is as follows：
(1) valve c, f, h, g are closed；Priority Open valve d, e, b, a.
(2) blow-down tank dust-laden emptying gas enter Whirlwind barrel with certain operating mode gas velocity through valve a from dusty gas entrance
Cyclonic separation is carried out, realizes that gas-solid is separated first, trapping fine powder, through valve d, surge tank, falls into collecting tank from fine powder discharge gate,
Carry dusty gas and filtration barrel body ascended into by whirlwind riser, then by filter screen filtration, realize that gas-solid is separated again,
Filtering fine powder is fallen into Whirlwind barrel, and clean gas is out vented from gas inlet and outlet through valve b.Gas-solid separating device separation effect
Rate is not less than 96%；
(3) when pressure difference is more than 1.0MPa before and after separator, emptying need to install the muffler of identical circulation area additional；
(4) valve b is closed, successively Open valve a, c, extraneous gas (nitrogen, carbon dioxide or air etc.) is anti-to screen pack
Blow, afterwards into blow-down tank pressurising, make emptying pressure tank slightly above system pressure.
(5) every time pressure release, pressurising alternately, it is ensured that filter screen effective filtration area.When enabling again, c, f, g, h valve
For closed mode；A, b, d, e valve are opening.
The utility model can realize the emptying of normal pressure or pressurization static bed, fluidized-bed gasification furnace coal lock, ash lock and flying dust tank
And conveying, the advantage of this method is：
1) whirlwind air inlet, is greatly decreased impact and abrasion of the pressure dusty gas to equipment, can substantially increase gas-solid point again
From efficiency；
2) strainer screen, which reinforces spoke and baffle plate, can effectively prevent that filter screen is deformed when pressure difference is big before and after filter screen；
3) blowback air effectively can prevent screen pack from blocking, and keep strainer filtering area and pipeline, unobstructed, the increase filter of valve
Net the life-span；
4) muffler can obviously reduce emptying noise, environment-friendly.
