The front-stage adsorption filtration zone comprises

Cleaning solution storage tank 1, cleaning solution storage tank 1 installs the last lateral wall at purification box 11, installs shower nozzle 2 on the cleaning solution storage tank 1.

Honeycomb formula adsorbs filter screen 7, and honeycomb formula adsorbs filter screen 7 is "V" type of inversion, and honeycomb formula adsorbs filter screen 7 can also divide into two-layer setting simultaneously. The honeycomb type adsorption filtering material 7 is mainly prepared by mixing active carbon, sepiolite and polypropylene fiber according to the ratio of 3:2:2, has strong hydrophobicity and lipophilicity, and is prevented from being decomposed and falling off due to washing of cleaning solution. The honeycomb type adsorption filter screen 7 is arranged in the purifying box body 11, and the spray head 2 faces the honeycomb type adsorption filter screen 7. The earlier stage adsorption filtration area is also provided with a flue gas induction element 12, the spray head 2 is an adjustable spray head, and the adjustable spray head is connected with the flue gas induction element 12 through an electric signal. The smoke sensing element 12 can sense the oil smoke concentration, and can control the spray head 2 to be opened to spray cleaning liquid after reaching a threshold value. The smoke sensing element 12 consists of a TGS2100 type semiconductor gas sensor, a JTY-HS-BK801 type smoke detector and a JWSL-12W2 type temperature and humidity sensor, the concentration of oil smoke can be monitored more accurately by combining the three, an electric signal can be timely and quickly transmitted to the central processing unit through an internal circuit, when the oil smoke reaches a set threshold value, the central processing unit is connected with a circuit of the spray head 2, and a spray head valve is opened to spray cleaning liquid.

The detachable oil collecting tank 8 is arranged on the lower side wall of the purifying box body 11 and is used for collecting cleaning liquid containing oil dirt washed off from the honeycomb type adsorption filter screen 7; an oil discharge port is formed in the detachable oil collecting tank 8, so that collected oil can be discharged conveniently.

The shunt adsorption area comprises a stainless steel filter screen which is detachably arranged on the bottom surface of the purifying box body 11; the stainless steel filter screen is provided with a shunt adsorption material 3. The shunt adsorption material 3 is formed by superposing and combining carbon-sandwiched cloth and glass fiber filter paper and is attached in the interlayer of the stainless steel filter screen. The stainless steel filter screen is integrally of a bent structure, so that the passing time of oil smoke gas is prolonged, the wind speed is reduced, the adsorption effect is increased, certain help is provided for subsequent photolysis and plasma purification, and the arrangement mode is shown in fig. 2.

The upper side wall of purifying box 11 is equipped with can dismantle shell 4, and can dismantle shell 4 and set up the upside in UV photolysis district. UV photodissociation district includes metal foam net 10, and is equipped with the catalyst on the metal foam net 10, and metal foam net 10 is "X" type, and metal foam net 10 sets up in purifying box 11 to fix in purifying box 11 through the buckle formula, convenient to detach and change.
