Specific implementation mode
Waste gas purification apparatus, from bottom to top by water tank 1, sedimentation basin 2, Venturi scrubber 3, turbogrid tray and spray equipment 4,
8 eight layers of gas-liquid separator 5, activated carbon+catalyst 6, wind turbine 7, silencer combination of facilities form.
First layer：Water tank.Increasingly in short supply with water resource, efficient water resource is using also widely being paid close attention to.Water
Water pump 9 is installed in case, using cycling use of water, by purified water, recycling.On the one hand the waste of water resource is reduced, it is another
Aspect can also reduce cost, reduce running cost.
The second layer：Sedimentation basin.Sedimentation basin is a kind of device that suspended matter in water removal is removed using precipitation.It is miscellaneous in sewage
Matter settles in sedimentation basin, and top clean water flows into water tank by filter, secondary filter, and water resource recycles.Periodically
Filter is replaced, prevents impurity from bringing into Venturi tube or sprinkling equipment, influences clean-up effect.
Third layer：Venturi scrubber.The Venturi scrubber is made of four Venturi tubes.Four Venturi tubes point
Not towards 4 directions, the first Venturi tube is adjacent with the second Venturi tube, and third Venturi tube is adjacent with the second Venturi tube,
Third Venturi tube is adjacent with the 4th Venturi tube.
The entrance of first Venturi tube is towards front, and the entrance of the second Venturi tube is towards the right side, third venturi
The entrance of pipe is towards below, and the entrance of the 4th Venturi tube is towards the left side.
The contraction section of first Venturi tube is connect with the contraction section of third Venturi tube by pipeline；Second Venturi tube
Contraction section is connect with the contraction section of the 4th Venturi tube by pipeline.
Gas enters Venturi tube collapsible tube, and circulation area reduces, and air velocity increases, and reaches gas stream in trunnion front end
Fast maximum value.At nozzle, liquid velocity is less than gas velocity, and under the influence of gas, liquid is atomized, the liquid after atomization and gas
Body interacts, and forms mixture.In diffuser, gas flow rate reduces, the water after large granular impurity and part atomization, can be straight
Cohesion is connect, second layer sedimentation basin is fallen into.And the small particles and mist in gas continue to rise, into the 4th layer.Text
Washer vertical view is shown in Fig. 2 in mound.
4th layer：Turbogrid tray and spray equipment.Gas flows up, and first passes through turbogrid tray, trepanning on turbogrid tray, it is therefore an objective to
Increase gas liquid interfacial area, increase the water content of gas so that a part of gas-liquid dirt mixture, can on turbogrid tray coalescence, fall
Enter sedimentation basin.And sprinkling equipment is installed on the top of turbogrid tray, is sprayed water downwards, is played the role of double purification gas.Sprinkling equipment
Vertical view is shown in Fig. 3.
Layer 5：Bent-plate-type gas-liquid separator 5.Entrainment mist in the gas phase or dust are detached, are a kind of point
From the gas-liquid separator that efficient, resistance drop is small, allowable superficial gas velocity is big, choke preventing function is strong.
When the gas containing mist flows through bent plate gas-liquid separator with certain speed, since the inertial impaction of gas is made
With mist collides and is attached to over the surface of the panel with separator board.The diffusion of mist in plate surface, mist gravitational settling,
So that mist is formed larger drop and move forward to separating plate turning with air-flow, due to turning to centrifugal force and its and separating plate
Rubbing action, suction-operated and liquid surface tension so that drop is increasing, until the drop gathered arrives greatly its own
The gravity of generation be more than gas climbing power and surface tension of liquid resultant force when, drop is just divided from gas-liquid separation plate surface
From getting off.The multidirectional structure of bent plate gas-liquid separator increases the chance that mist is captured, and the mist not being removed is next
Turning is captured by identical effect, such repeated action, to substantially increase demisting efficiency.Gas passes through bent plate
After gas-liquid separator, substantially free of mist.
Separating step：
A gases enter after bent plate gas-liquid separator the channel for being separated into many sub-threads；
For b under the action of inertia force, the collision of drop mist forms liquid film in separating plate on piece；
C liquid films move forward to turning with air-flow and are separated；Gas-liquid separator fundamental diagram is shown in Fig. 4；
It is thoroughly removed by identical effect at the drop mist that d is not removed several turnings under.
Bent plate gas-liquid separator separates are efficient, and resistance is small, are not easy to block, and mounting area is small, and economical operation safely may be used
It leans on, it is easy to operate.
Layer 6：Activated carbon+catalyst.Activated carbon or other catalyst can be installed, according to the demand of user for eliminating
The harmful substances such as formaldehyde, benzene homologues.
Activated carbon can physical absorption and chemisorption.Activated carbon is a kind of very tiny carbon granule, there is prodigious surface
Product, and also have more tiny hole --- capillary in carbon granule.This capillary has very strong adsorption capacity, due to carbon granule
Surface area is very big, so energy and gas（Impurity）It comes into full contact with.When these gases（Impurity）Encounter capillary to be adsorbed, play
The effect of purification.With inhale taste, detoxification, deodorization, dry, it is mould proof, sterilization, purification etc. comprehensive functions.
Layer 7：Wind turbine.Wind turbine sucks impure, poisonous and hazardous gas from venturi nozzle, passes through waste gas purification
Multilayer purification inside device, is finally discharged purified gas from top.
8th layer：Silencer.Silencer is mounted on top, allow air-flow by and can effectively prevent, reduce noise
Propagation, be reliable control noise tool.
It connects and is connected by screw bolts between each layer of waste gas purification apparatus, on the one hand can shorten the set-up time, it is easy to disassemble
It repairs, reduces maintenance workload；On the other hand it can increase and decrease the number of plies according to user's actual need, optimize mount scheme, to reach
With minimum price, most efficient purification is completed.
Outside uses global design, without in disorder sense, simple and beautiful and is readily transported.Control system is programmed using PLC,
Touching liquid-crystal display screen is installed in outer surface, and operating personnel can be turned on and off purifier according to actual conditions, or adjust pump
Flow, Venturi nozzle flow, sprinkling equipment, the parameters such as fan delivery.
