The water washing and spraying device 3 comprises a rotating head 3-1 rotatably mounted with a rotating head mounting seat 3-5, the rotating head 3-1 is provided with a water outlet pipe which is vertical to the vertical central plane and penetrates through, a water outlet 3-6 at the end part of the water outlet pipe is connected with a horizontal water distribution pipe 3-3, the horizontal water distribution pipe 3-3 is connected with the rotating head 3-1 through a steel wire rope 3-2, and the water outlet pipe is cut off in the rotating head 3-1 so that water fed by a water pump 8 is discharged from the water outlet 3-6; the rotating head 3-1 is connected with a rotating shaft 3-8, the rotating shaft 3-8 is rotatably installed with a rotating head installation seat 3-5, and impellers 3-9 are arranged on the rotating shaft 3-8 in a circumferential array mode.

The water supplied by the water pump 8 is supplied to the rotating head 3-1 through the water inlet pipe joint 3-4, the impeller 3-9 drives the rotating head 3-1 to rotate under the action of water pressure, so that the rotating water distribution of the horizontal water distribution pipe 3-3 is realized, and the water is uniformly scattered;

the wet scrubbing treatment mode is used for treating particulate matters with the particle size of more than 0.3-1 mu m in the waste gas and removing partial gaseous pollutants in the waste gas. The basic principle is that effective contact between gas and liquid is utilized, the liquid adsorbs pollutants in the gas, and after granular pollutants in the gas flow are contacted with a washing liquid, liquid drops or a liquid film are diffused and attached to particles in the gas flow or are humidified on the particles, so that the particles are separated and removed under the action of gravity, inertia and the like; gaseous pollutants are conveyed by means of flocculation molecular diffusion and the like, chemical substances can be added into the cleaning solution, the separation purpose is achieved through a chemical reaction mode, and then clean gas is separated from polluted liquid, so that the purpose of purifying the gas is achieved.

The UV photolysis purification device 5 adopts vacuum ultraviolet rays (with the wavelength range of 185-253.7nm) in a specific waveband to destroy chemical bonds of organic waste gas molecules and enable the organic waste gas molecules to be cracked to form atoms or groups in a free state; meanwhile, oxygen in the mixed air is cracked to form free oxygen atoms and combined to generate ozone. The ozone with strong oxidizing property and atoms generated by cracking organic waste gas molecules generate oxidation reaction to form H₂O and CO₂. The whole reaction process does not exceed 0.1 second, and the purification effect is related to the bond energy of waste gas molecules, the concentration of the waste gas and the oxygen content. The whole purification process does not need to add any chemical auxiliary agent or special limitation condition.

The active carbon adsorption device 6 utilizes the unbalanced molecular attraction or chemical bond force on the solid surface of the active carbon, so that when the solid surface contacts with gas, the gas molecules can be attracted, concentrated and kept on the solid surface, and pollutants are adsorbed, thereby the operation is simple and convenient. The tower adopts honeycomb activated carbon, and has the characteristics of large specific surface area, small through hole resistance, developed micropores, high adsorption capacity, long service life and the like.

In the small deodorization integrated purifier of the embodiment, the body is provided with the centrifugal fan, the centrifugal fan sucks waste gas from the air inlet, and the waste gas passes through the water washing spray device, the demisting module device, the UV photolysis purification device and the active carbon adsorption device in sequence and is discharged from the air outlet;

the negative pressure formed by the centrifugal fan leads the suction force of the gas to be treated into the water washing and spraying device 3, and the purification and deodorization are realized through the following steps:

(1) the waste gas passes through the spraying chamber at a slow speed of about 1.5m/s, the contact time is about 1 second, the spraying liquid in the spraying chamber is atomized by a polyhedral hollow sphere filler atomizer (adopting the existing device in the market) to form liquid drops or liquid films which are diffused and attached to particles in the gas flow or humidified on the particles, and the particles achieve the purpose of separating and removing particulate matters and partial water-soluble pollutants in the waste gas by means of the actions of gravity, inertia and the like;

(2) the waste gas passes through a demisting module device and a partition plate filter (adopting the existing silk screen demister on the market) above the washing spray device 3, so that water mist and remaining micro particles generated by the washing spray device 3 are removed, the UV photolysis purification device is protected better, the water mist and the micro particles cannot be attached to the UV lamp tube, the efficiency of the UV lamp tube is reduced, and meanwhile, the water mist is filtered and removed to protect the electrical elements of the UV photolysis purification device;

(3) the UV photolysis purification device 5 (adopting the existing UV photolysis equipment on the market) cracks the waste gas by utilizing different UV light sections, and ozone is generated by air under the irradiation of the UV light to further oxidize and decompose the waste gas;

(4) finally, the obtained product is fully contacted with the active carbon by an active carbon adsorption device 6 (the existing active carbon adsorption device on the market is adopted), and the processes of gas adsorption and trapping, odor removal, oxidation and the like are carried out in the active carbon adsorption device.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
