Description
Technical field
The present invention relates to gas cleaning plant field, a kind of more particularly to spiral waste gas recovery processing unit.
Background technology
In traditional catalyst manufacturing process in addition to using the solid materials such as silica, aluminium oxide and molybdenum nickel tungsten,
Dry, calcining process also produces the exhaust gas such as a large amount of high-temp chlorination hydrogen, nitrogen oxide, and exhaust gas discharge drastically influence scene and peripherally
Area's environmental sanitation, or even form the adverse consequences such as acid rain.With national economic development, catalyst industry exhaust gas problem must obtain
Deal carefully with, exhaust gas treatment technology must improve.
The content of the invention
The purpose of the invention is to be purified exhaust gas, a kind of spiral waste gas recovery processing unit has been provided.
The present invention provides a kind of spiral waste gas recovery processing unit, it is characterised in that:The spiral exhaust gas returns
Receive processing unit, including gas handling system 1, pipeline 2, interface channel 3, sprayed tank taper cover 4, water mist pressurized liquid spray device 5, maintenance
Baffle 6, is classified process tank 7, device pedestal 8, water tank 9, intake tunnel 10, high temperature resistant cyclone dust collectors 11;
Wherein:Gas handling system 1 is connected with high temperature resistant cyclone dust collectors 11, and gas handling system 1 passes through pipeline 2 and interface channel 3
It is connected with sprayed tank taper cover 4, sprayed tank taper cover 4 is below classification process tank 7, and being disposed with water mist in classification process tank 7 adds
Flusher 5 is pressed, 7 side of classification process tank is arranged in 8 top of device pedestal, water tank 9 with maintenance baffle 6, classification process tank 7
It is connected with water mist pressurized liquid spray device 5,9 top of water tank carries intake tunnel 10.
The high temperature resistant cyclone dust collectors 11, generally cone-shaped structure, upper side enter passage with flue gas, top
Portion is exhanst gas outlet, and exhanst gas outlet is connected with gas handling system 1, and lower part is dust outlet.
The overwhelming majority of swirling eddy is moved, shape to cone bottom from top to bottom in the shape of a spiral along wall from cylinder
Into the outward turning dust-contained airflow of decline, density is far longer than the grit of gas and got rid of by caused centrifugal force in strong rotary course
To wall, grit is once contacted with wall, just lose inertia force and momentum and the gravity of itself by entrance velocity along under wall
Drop into flue-dust retainer.The air-flow that rotation declines axis part of along deduster after cone bottom is reached is transferred upward and is formed
The interior rotational airflow of rising, and discharged by the exhaust pipe of deduster.From another fraction air-flow of air inlet person who lives in exile, then removed to whirlwind
Flow, then flow downward along on the outside of exhaust pipe, when reaching exhaust pipe lower end, i.e., with rising on counter steer at dirt device head cover
Central gas stream is together from tracheae discharge of slandering, and also companion is pulled away the grit being dispersed therein.
The water mist pressurized liquid spray device 5 is Multi-layer sprinkling structure, per Rotating fields for multiple nozzles be distributed on annular into
On water pipe.
The water tank 9 is corrosion-resistant material materials and parts, or inside carries corrosion-inhibiting coating.
The flue gas of the high temperature resistant cyclone dust collectors 11 enters channel centerline, positioned at high temperature resistant cyclone dust collectors top
The tangential direction of side.
Caused exhaust gas contains a small amount of particle micronic dust and acid gas to high-temperature roasting furnace in process of production.It is each useless
Gas point source exhaust gas is absorbed through gas collection fan housing respectively to be pooled in pipeline, is collected rear head and is entered in high temperature resistant dust collector, carries out the
The dust removal process of one step, removes the material micronic dust that gas is carried out.Waste gas absorption spray column is entered back into, is inhaled with tower neutral and alkali
After receiving liquid counter current contacting, acid exhaust gas is got off by absorption, and purified gas empties after demister demisting in tower again;
Alkaline absorption solution in circulating slot recycles.
Exhaust gas lye spray absorber has small resistance, saving energy, low noise, treatment effeciency high, can handle hydrogen chloride gas
The new type purification tower of the gases such as body (HCL), sulfuric acid mist (H2SO4), oxides of nitrogen gas (NOx), it has, and purification efficiency is high, ties
Structure is compact, floor space is small, corrosion-resistant, ageing-resistant performance is good, it is light-weight the characteristics of.It is suitable for discharging certain density corrosion
Property acid mist gas, is mainly used for the places such as chemical industry, electronics, hospital, institute, research center.
Because the height of exhaust duct is higher, under conditions of safety is taken into full account, this time the supporting structure of exhaust duct is all adopted
Supported with steel structure, also allow for later maintenance, size is determined according to site specific.
The exhaust gas that need to be handled, after the air inlet section on absorption tower is pressed into by centrifugal blower, vertically upward with spray section from top to bottom
Absorbing liquid play neutralization reaction, reduce exhaust gas concentration, then proceed to be upwardly into packing section, exhaust gas baton round roll about again with
Absorbing liquid plays neutralization reaction, and dehydrator section is entered after exhaust gas concentration is further reduced, and sloughs drop, purified gas discharge
Air.
Each component must be checked and checked before installation, if any defect or deformation, to carry out can after polishing finishing
Installation.Acid fog absorption tower assembles and the connection of spray pipe and accessory must be tight, with liquid-leakage preventing.After installing, it is necessary to clear
Except the debris in Ta Nei and nebulisation cycle pipeline and in filtrate ring, in order to avoid block fluid strainer and nozzle.
NaOH solution concentration should maintain 6%-15% scopes in fluid storage tank, when concentration is less than concentration is required, it is necessary to add
Solubilization liquid.The salinity generated in fluid storage tank by acid-base neutralization carries out periodic replacement solution according to actual use situation.
Purifying column must have special messenger to be responsible for, running check;Whether wind turbine and pump operation are normal, fluid strainer and nozzle
Whether block, whether liquid level normal, floating ball whether failure, absorb neutralizer solubility whether in prescribed limit etc., such as find
Problem, should solve in time.
Wind turbine and pump switch program:During start, first blow in machine, rear boiling water pump;During shutdown, first cut out the pump, then Blowing stopper.
To prevent the switch of wind turbine from causing fluid storage tank liquid level to lift, therefore must accomplish:When wind turbine starts, open floating ball and supply
Water valve;When wind turbine stops, it is necessary to first closing floating ball water supply valve.
Advantages of the present invention:
Waste gas absorption processing procedure caused by can be applied to catalyst drying and roasting process, reach rich in hydrogen chloride,
Nitrogen oxide and dust removal efficiency technical indicator, and operating cost is than relatively low.Technological process, deduster, spray absorber etc. are main
Structure and thinking design are unique, from the problem of environmental pollution for solving or reducing catalyst drying and roasting process to a certain degree.
