Detailed Description

As shown in fig. 1 and fig. 2, the utility model discloses an indoor emission type oil smoke purification device, include casing 14 and install microorganism liquid degradation device, centrifugal separation device, filtration adsorption equipment, electrostatic purification device, UV photolysis oxidation unit in casing 14 from air intake 1 to air outlet 15 in proper order.

Wherein, little biological fluid degradation device includes liquid reserve tank 3 and super little atomizing nozzle 2, and super little atomizing nozzle 2 aims at centrifugal separation device and passes through pump connection liquid reserve tank 3, and the deodorant is filled in liquid reserve tank 3. The microorganism deodorization liquid is atomized by a water pump at the air inlet section through a special ultramicro atomization nozzle 2 to form a fog shape, and the fog shape is mixed with the entering oil smoke, and the microorganism in the deodorization liquid is utilized to degrade the peculiar smell of the oil smoke.

The centrifugal separator consists of an impeller and a motor 5 arranged on the impeller, adopts a mechanical oil removing technology and purifies the oil smoke by utilizing the gas power of a fan. Oil-smoke separation is realized inside the impeller through a two-way flow theory of hydrodynamics. By changing the angle of the blades and the form of the blades, the oil smoke molecules are collided and gathered on the impeller disc and the blades. The oil fume is in the form of particle oil mist and is thrown into the inner wall of the box body by centrifugal force and flows out of the oil leakage pipe.

The filtering and adsorbing device comprises a primary filter material section 6 and an adsorbing and filtering material section 7, wherein the primary filter material section 6 and the adsorbing and filtering material section 7 are divided into an upper cavity and a lower cavity.

Elastic fiber filter materials such as sponge are filled in the primary filter material section 6, so that trapped oil fume molecules can be effectively adsorbed, and the filter materials are arranged in a V shape in the cavity, so that the capture rate is high, and the oil fume isolation effect is good; the compression performance is good, the shape of the filter can be kept unchanged, and the filter fiber holes are favorable for storing oil smoke particles; the filter material is black in appearance, has elasticity and low pressure loss, and has excellent oil smoke trapping efficiency;

the contaminants generally move with the air stream by inertial or random brownian motion or under the influence of some field force, and when the particles collide with the pores of the elastic fiber media, the particles adhere to the surfaces of the fiber pores due to van der waals forces. Particles entering the filter medium have more chance to hit the medium, the medium is stuck when hit, and smaller particles hit each other and are stuck to each other to form larger particles to be settled. The tiny particles in the oil smoke are intercepted and filtered through the functions.

The adsorption filtering material section 7 adopts a carbonaceous porous adsorption material, such as calcined coke, and utilizes the larger specific surface area thereof to efficiently adsorb VOC pollutants in the oil fume. The treatment load of the subsequent purification section is reduced.

Different from the electrostatic purification mode of directly utilizing the electric field polar plate to adsorb oil fume particles, the effective working time of the electric field is prolonged, and low-carbon operation is achieved.

The UV photolysis oxidation device consists of catalytic plates 13 and UV lamps 12, and a plurality of UV lamps 12 are uniformly distributed between the two catalytic plates 13. The UV photolysis oxidation mainly comprises a cavity generated on the surface of the photocatalyst under the irradiation of ultraviolet light and a hydroxyl radical generated by the further reaction of the cavity and water molecules on the surface of the photocatalyst, wherein the cavity and the hydroxyl radical both have extremely high oxidation potential energy, and the cavity and the hydroxyl radical have extremely high oxidation potential energyUnder the strong oxidation action of the radical free radical, the organic matters which are not oxidized completely in the light direct oxidation area are further oxidized and finally are completely oxidized into CO₂And H₂And O. The photocatalytic oxidation zone is a gas-solid reaction, so that sufficient contact between the gas and the photocatalyst plate must be ensured. For this reason, the catalytic plate 13 uses a foamed nickel plate having a three-dimensional structure with a very large specific surface area as a substrate and the surface is coated with a titanium dioxide photocatalyst, increasing the contact surface between the gas and the photocatalyst plate.

In order to realize the automatic cleaning of the electrostatic purification device, the spiral nozzle 9 which can automatically wash is arranged above the ionization area 8 and the adsorption area 10, the other end of the spiral nozzle 9 is communicated with the liquid storage tank 3, when the working time of the oil fume purification device meets the control setting, the oil fume purification device can automatically spray water mist to clean the oil stain on the electrostatic purification device, the liquid collection box 11 is arranged below the filtering and adsorption device, and the intercepted oil liquid and the cleaning sewage flow into the bottom oil collection box 11 to be discharged.
