Technical field
The present invention relates to field of environment protection, more particularly to a kind of equipment of use plant extraction liquid washing, purifying waste gas.
Background technology
With the development of society, environmental problem is increasingly becoming focus of concern, and air quality is must during people live
The big problem that must be faced, is that the waste gas that a large amount of commercial production are produced is entered in air the reason for air quality deteriorates, waste gas
Purification become the indispensable device of commercial production, present air purifying process is typically harmful to using water curtain dedusting, activated carbon adsorption
The techniques such as composition, are also had and waste gas are washed so as to remove the skill of the harmful components in waste gas by the cleaning mixture of special composition
Waste gas typically all is passed through in absorption tower to realize by art, and absorption tower is widely used in various field of industrial production such as chemical industry
GAS ABSORPTION, purification, its version is varied, using it is more be packed tower and plate column, this kind of tower Yin Tanei
There are filler and tower tray in portion, there is the deficiencies such as resistance is big, cost is high, clear up and maintenance management workload is big.And these technologies
Need to consume substantial amounts of cleaning mixture, and waste gas absorbs not abundant enough with the contact of cleaning mixture so that clean result is undesirable, finds
A kind of economical rationality, the preferable washing process of clean result become in field of environment protection a very urgent problems.
The content of the invention
It is an object of the invention to provide a kind of device purified to waste gas by utilization plant extraction liquid, it is desirable to knot
Structure is simple, economical and practical, safe and reliable, the advantage that clean result is good.
A kind of waste gas purification apparatus of the present invention, including waste gas is passed through flow regulator, scrubbing tower and cleaning mixture and reclaims
Input equipment, is characterized in that the centre of described scrubbing tower contains several cleaning mixture ranges of atomization, in scrubbing tower tower body most
Fixed demisting net being provided with above, also having Powerless centrifugal demister in the cervical region of scrubbing tower, waste gas to be clean leads to
The bottom for sending into tower after waste gas access conduit is passed through flow regulator with appropriate flow velocity by input pipe is crossed, gas is to upstream
In dynamic process, input equipment feeding scrubbing tower the cleaning mixture that be atomized are reclaimed with by cleaning mixture in several ranges of atomization
It is fully contacted, the washed liquid of harmful components therein absorbs, and purified gas passes through demisting net and Powerless centrifugal demisting
Lead to gas outlet after the abundant demisting of device.
Described cleaning mixture reclaims input equipment to be collected holding vessel, pressure by cleaning mixture and adjusts pump, supervisor, valve, is in charge of
Constitute with mist pipe, the cleaning mixture that cleaning mixture is collected in holding vessel sends into supervisor after pressure adjusts pump pressure regulation, by some
By some some mist pipe be in charge of and send into insertion tower body after valve, some mist pipe are uniform according to appropriate mode arrangement form
Intensive range of atomization, above-mentioned mist pipe is the hollow pipe being made of stainless steel, its one end closing, and gather on tube wall pore, pipe
Another end opening and screw thread is provided with outside tube wall, mist pipe inserts tower body, one end of closing by the hole opened up on tower body
The preformed hole on insertion tower body opposite, mist pipe keep one end of sealing, opening to connect with the nut being in charge of by screw thread with tower body
Connect, centre adds sealing ring and keeps sealing.Described demisting net is the screen cloth being made of stainless steel, installed in tower body and tower neck
Junction, cleaning mixture residual mist when purified gas passes through demisting net in gas flow into the bottom of tower after being retained by rustless steel
Holding vessel is collected into cleaning mixture；Described Powerless centrifugal demister is the device of a similar windmill, and centre has and turns
Moving axis, surrounding have some blades, installed in the cervical region of tower, are rotated around rotary shaft by gas impact rear blade, are remained in gas
Washing liquid mist is retained and is thrown to tower wall stream by blade and enters cleaning mixture collection holding vessel to the bottom of tower.
Preferably, in described range of atomization between mist pipe it is arranged in parallel in one plane, it is also possible to interlock up and down
Arrangement, is spaced 10 to 20 centimetres, and the uniform densely covered and thickness in range of atomization of formation is at 30 to 50 centimetres.
A kind of waste gas purification apparatus of the present invention, is a kind of integrated no-arbitrary pricing atomizing gas cleaning plant.In this dress
The vapour-liquid switch such as middle no-arbitrary pricing and gas-liquid exchange tower disk is put, cleaning mixture mist pipe is input into into after pressurization, due to pressure
So that cleaning mixture sprays to form spraying by the pore being atomized on tube wall, many mist pipe reasonable layouts produce what is uniformly gathered
Cleaning mixture range of atomization, waste gas is after flow regulator with certain flow velocity from the bottom up of scrubbing tower flowing flow process
In pass through range of atomization, cleaning mixture is fully contacted with waste gas, harmful components composition formation chemical reaction corresponding with cleaning mixture from
And harmful components therein are removed, in order to ensure clean-up effect, several ranges of atomization are set so that gas to be clean in scrubbing tower
Body constantly passes through range of atomization, and usually three ranges of atomization can cause the completely washed liquid absorption of harmful components in waste gas.For
Save and use cleaning mixture, and also to not allowing cleaning mixture air to be entered with purified gas causes new pollution, treating
Purification gas through behind range of atomization, using stainless steel mesh and Powerless centrifugal demister by the washing liquid mist pearl in gas
Retain and be back to cleaning mixture and collect holding vessel reuse.The device of the present invention is without filler and gas-liquid exchange tower disk, system
Resistance is little, reduces power of fan, energy efficient；Liquid is atomized by atomizer completely, and gas-liquid exchange area is big, is absorbed, net
Change abundant；Using two-stage demister, the drop in gas has been reclaimed to greatest extent, improve the response rate of liquid, reduced
The loss of absorbing liquid；Yin Benta eliminates filler and tower tray, also just eliminates the support meanss such as filler and tower tray support and assembly and disassembly
Manhole of filler etc., both reduced technique for production, and alleviated the weight of tower body again, become simplified as installation and basis, saved
About investment；This device tower body is Steel material or PP or fiberglass integrally winds material, and clean-up stage is without segmentation adpting flange, intensity
High, without leakage hidden danger.The main harmful gass that this kind of device is processed are the mineral acid waste gas such as sulfuric acid mist, salt acid mist, and with
Vegetation water is all kinds of foul smell of absorbent purification so as to which meet the requirement of environmental protection, its effect are more equal than traditional packed tower and plate column
There is greater advantage.Therefore, a kind of waste gas purification apparatus of the invention has structurally simple, economical practical, safe and reliable, washing effect
Really good advantage.
