At the upper surface of the composite photocatalytic housing 1 at one end of the VP deodorizing membrane air outlet 6 away from the deodorizing membrane housing 3, a deodorizing fan 7 is installed. The bottom end of the deodorizing fan 7 is communicated with the top end of the air duct 16;

[0030] During use, through the setting of the deodorizing fan 7, air can enter the deodorizing membrane housing 3 through the control valve 5 and the VP deodorizing membrane air inlet 4.

[0031] This device adopts a composite form of the first titanium dioxide nickel mesh layer 10, the first ultraviolet lamp group 13, the second titanium dioxide nickel mesh layer 11, the second ultraviolet lamp group 14, and the third titanium dioxide nickel mesh layer 12, so that the light waves of the ultraviolet lamps and the titanium dioxide nickel mesh layers are fully utilized. The ultraviolet lamps of the first ultraviolet lamp group 13 and the second ultraviolet lamp group 14 are arranged in two columns. Under normal operation, one column of ultraviolet lamps is turned on and the other is in standby. Moreover, each ultraviolet lamp can be controlled individually. When a malfunction occurs in the operating ultraviolet lamp, the corresponding standby lamp tube is turned on to achieve seamless connection and ensure the waste gas purification effect.

[0032] The filling layers of the VP deodorization dialysis membrane 19 can be designed according to the quantity and concentration of the malodorous waste gas to be treated in the deodorization membrane housing 3. Under each layer of the VP deodorization dialysis membrane 19, there is a VP deodorization membrane support 18, and all the VP deodorization membrane supports 18 are in a mesh shape. The VP deodorization dialysis membrane 19 can naturally dialyze outwards. A control valve 5 is installed on the VP deodorization membrane air inlet 4 of the deodorization membrane housing 3. The VP deodorization membrane air outlet 6 is connected to a deodorization fan 7 with frequency conversion control. The deodorization fan 7 and the control valve 5 are linked and controlled to synchronously adjust the opening degrees of the deodorization fan 7 and the control valve 5 according to the air volume and concentration of the waste gas, so as to ensure the deodorization effect of the waste gas. The outlet of the deodorization fan 7 is connected to a gas guide pipe 16. The VP deodorization molecules enter the air distribution pipe 15 through the gas guide pipe 16. The air distribution pipes 15 are evenly distributed according to the width and requirements of the composite photocatalytic housing 1. Each air distribution pipe 15 is provided with through holes to facilitate the rapid diffusion of the VP deodorization molecules, so as to quickly and efficiently wrap and purify the malodorous molecules in the waste gas.

[0033] When the embodiment of the present application is in use, first, the waste gas enters the composite photocatalytic housing 1 from the composite photocatalytic air inlet 2, and is preliminarily treated through the polypropylene fiber filter layer 8 to remove impurities such as dust, oil stains, and particulate matters in the waste gas. Then, it is further treated through the carbon fiber layer 9 to adsorb some organic gases, such as benzene, aldehydes and ketones, alcohols, hydrocarbons, etc., and malodorous substances. When the waste gas enters the first titanium dioxide nickel mesh layer 10, the second titanium dioxide nickel mesh layer 11, and the third titanium dioxide nickel mesh layer 12, the first ultraviolet lamp group 13 and the second ultraviolet lamp group 14 are turned on, and ultraviolet light with a specific wavelength catalytically excites nanoscale titanium dioxide to generate electron-hole pairs. Due to the existence of a large number of defects and dangling bonds in the nanomaterials, these defects and dangling bonds can capture electrons or holes and prevent the recombination of electrons and holes. These captured electrons and holes diffuse to the surface of the particles respectively, and a strong redox potential can be generated, thereby achieving the oxidative degradation of organic waste gas. The VP deodorization dialysis membrane 19 inside the deodorization membrane housing 3 has unidirectional dialysis and can be naturally released inside the deodorization membrane housing 3. Subsequently, the control valve 5 is opened and the deodorization fan 7 is started. Under the action of the deodorization fan 7, air enters the deodorization membrane housing 3 through the control valve 5 and the VP deodorization membrane air inlet 4, mixes with the VP deodorization molecules therein, and then enters the air distribution pipe 15 inside the composite photocatalytic housing 1 through the VP deodorization membrane air outlet 6 and the deodorization fan 7. The air mixed with VP deodorization molecules enters the composite photocatalytic housing 1 uniformly through the air distribution pipe 15, captures the malodorous molecules in the waste gas after photocatalytic oxidation, and wraps and purifies the malodorous molecules, thereby achieving the deodorization and purification effect of the waste gas. The purified waste gas is discharged from the composite photocatalytic air outlet 17, thus completing the use of the deodorization integrated device.
