Embodiment 1

[0053] combined with figure 1 , it can be seen that the exhaust gas treatment process is as follows: first, the exhaust gas enters the interior of the photo-oxygen machine through the inlet (101) of the photo-oxygen machine, and then enters the UV photocatalytic oxidation stage through the splitter plate (102) and the primary filter (103). In 104, its power is 150W) and the UV light and photocatalyst (105 in the figure, its composition is TiO 2 , the coating weight is 4g / m 2 ), the exhaust gas molecules are degraded into harmless CO 2 and H 2 O. This embodiment provides a UV light oxygen machine without any special reflection design on the inner surface, and uses the mixed gas of toluene and air as the waste gas source, controls the concentration of toluene to be 100ppm, and then under different wind speeds (1~5m / s) test the exhaust gas concentration at its outlet, and calculate the purification efficiency of the UV light oxygen machine, such as Figure 4 shown.

Embodiment 2

[0055] combined with figure 1 And attached figure 2 , the present embodiment provides a kind of UV photo-oxygen machine and its manufacturing process that the inner surface is covered with aluminum foil, in the position of certain width (such as figure 1 The position shown in 106) is pasted with an aluminum foil tape with a thickness of 0.1mm (such as figure 2 ), and the orientation of the aluminum foil attached to the surrounding inner surfaces is the same (the two opposite inner surfaces are both smooth surfaces), then test the exhaust gas concentration at the outlet at different wind speeds, and calculate the purification efficiency of the UV light oxygen machine, Such as Figure 4 shown. In addition, it should be noted that the power of the UV lamp, the catalyst, the grammage of catalyst coating and the concentration of the exhaust gas source in this embodiment are all the same as those in Embodiment 1.

Embodiment 3

[0057] combined with figure 1 And attached figure 2 , this embodiment is basically the same as Embodiment 2, and also provides a UV light oxygen machine and its manufacturing process with aluminum foil on the inner surface. Or a position with a certain width on the inner surface of the shell between the foam photocatalysts (such as figure 1 The position shown in 106) is pasted with an aluminum foil tape with a thickness of 0.15mm (such as figure 2 ), and the orientations of the aluminum foils attached to two sets of opposite inner surfaces of the surrounding inner surfaces are perpendicular to each other (one side of the two opposite inner surfaces is a smooth side, and the other side is a dark side), and then at different wind speeds Next, test the exhaust gas concentration at its outlet, and calculate the purification efficiency of the UV light oxygen machine, such as Figure 4 shown. The power of the UV lamp, the catalyst, the grammage of the catalyst coating and the ...

Abstract

The invention provides a UV light oxidization machine with an inner surface coated with aluminum products and a manufacturing process thereof. The UV light oxidization machine comprises a shell, photolysis lamp tubes and targets, wherein a plurality of rows of photolysis lamp tubes are arranged in the UV light oxidization machine along a direction vertical to a gas flowing direction; a target carrying photocatalysts is arranged on one side of each row of photolysis lamp tubes; aluminum product layers with certain thickness are arranged on the inner surface of the shell between two rows of photolysis lamp tubes. According to the UV light oxidization machine and the manufacturing process thereof, the characteristics of high reflection rate of aluminum to short-wave ultraviolet light is used;the aluminum product layers with certain thickness are coated in suitable positions in the inner surface of the shell of the UV light oxidization machine, so that the utilization rate of the UV lightis increased; the UV light irradiation area of honeycomb or foam photocatalysts can be maximized; the manufacturing process of the UV light oxidization machine is simple in steps, convenient to operate and high in practicability.

Description

technical field [0001] The invention belongs to the field of UV photocatalytic oxidation waste gas treatment, in particular to a UV photooxygen machine whose inner surface is coated with aluminum products and a manufacturing process thereof. Background technique [0002] In June 2015, my country promulgated the "Pilot Measures for Charging Volatile Organic Compounds", and the pilot industries include petrochemicals, packaging and printing. This is the first time that my country has restricted the emission of volatile organic compounds (Volatile Organic Compounds, VOCs) through economic means. In recent years, relevant policies, regulations and industry standards have involved more industries, and the supervision and inspection of environmental protection departments in various regions has also increased significantly. Therefore, finding an efficient and applicable VOCs treatment technology is an urgent problem for many companies to solve. At present, the mature technologie...
