[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1 As shown, combined withFigure 2 The utility model discloses a road tail gas treatment device that integrates lighting and tail gas treatment, which is arranged on the lamp pole of the street lamp 1 and comprises a shell 2, a coating 3 and a wind guide assembly 4.

[0026] The road tail gas treatment device can be fixed to the lamp pole of the street lamp 1 through the clamps or buckles.

[0027] The shell 2 is made of transparent or translucent material, which can be glass ceramic or transparent plastic material (for example, acrylic or polypropylene, etc.). The shell 2 is provided with an air inlet 201 and an air outlet 202 at intervals.

[0028] The coating 3 is coated on the inner surface of the shell 2. The coating 3 is a mixture of photocatalyst and long-afterglow material. The tail gas entering the shell 2 is subjected to photodissociation reaction under the action of the photocatalyst on the coating 3. The coating 3 emits light in a dark environment.

[0029] The mixture of photocatalyst and long-afterglow material is g-C3N4 / TiO2 / SrAl2O4:Eu 2+ ,Dy 3+ composite photocatalyst. The g-C3N4 is an organic semiconductor material composed of nitrogen and carbon elements, which has strong absorption capacity for ultraviolet light and visible light and can perform photocatalytic reaction using the visible light part of the solar spectrum. The g-C3N4 has a wide band gap (about 2.7 eV), and the positions of its conduction band and valence band are conducive to the separation and migration of electrons and holes, thereby improving the efficiency of photocatalytic reaction. TiO2 is a classic photocatalytic material, which can perform photocatalytic reaction using ultraviolet light (wavelength less than 387 nm) and can effectively degrade organic pollutants. TiO2 can generate electron-hole pairs under light, which has strong oxidation-reduction capacity for pollutants. SrAl2O4:Eu 2+ ,Dy 3 + is a rare earth doped material with long-afterglow luminescence property, in which Eu 2+ is the luminescence center, and Dy 3 + is the auxiliary dopant to enhance the luminescence performance. The material can emit visible light (long-afterglow) with long duration after light irradiation, which can effectively provide energy at night and provide certain lighting effect for the surrounding environment. The material can also enhance the visible light response of the photocatalytic reaction. Doping rare earth elements (such as Eu 2+ and Dy 3 +) can optimize the energy band structure of the material and further improve the activity of the photocatalyst.

[0030] The air guide assembly 4 is arranged in the shell 2; the air guide assembly 4 guides the external tail gas to enter the shell 2 through the air inlet 201 and is discharged through the air outlet 202, and meanwhile the tail gas is in full contact with the coating 3 on the inner wall of the shell 2 under the driving of the air guide assembly 4 to ensure the effect of the photocatalytic reaction.

[0031] In Figure 2 In a preferred embodiment shown in the drawings, the air inlet 201 is arranged on the end surface of the shell 2 close to the ground, or the air inlet 201 is arranged on the outer peripheral wall of the shell 2 close to the ground; the air outlet 202 is arranged on the end surface of the shell 2 away from the ground. The external tail gas is guided by the air guide assembly 4 to enter the shell 2 from the air inlet 201 below the shell 2, and the tail gas is purified through the photocatalytic reaction in the shell 2 and is discharged from the air outlet 202 on the top of the shell, thereby forming a circulating effective tail gas flow path.

[0032] In Figure 1 In a preferred embodiment shown in the drawings, the rain shield 5 is further arranged.

[0033] The rain shield 5 is arranged on the end of the shell 2 away from the ground and covers the air outlet 202; the rain shield 5 is also made of transparent or semi-transparent material.

The inner wall of the top and bottom of the shell 2 is provided with an axial connecting seat, and the two ends of the mandrel 42 are limited and installed through the axial connecting seat.

[0037] A plurality of blades 43 are arranged on the mandrel 42 and rotate with the mandrel 42. The blades 43 can be leaf plates. When the fan 41 sucks inward, the external airflow entering the shell 2 will drive the blades 43 and the mandrel 42 to rotate, and the plate surface of the blades 43 will fan the airflow to flow to the inner wall of the shell 2, thereby ensuring that the tail gas is in full contact with the coating 3.

[0038] In Figure 2 In a preferred embodiment shown in the drawings, the length of the blade 43 is not greater than the length of the mandrel 42, so that the rotation of the mandrel 42 is not hindered, and meanwhile the blade 43 also has a certain gap with the inner wall of the shell 2, so that the airflow can be in full contact with the coating 3.
