Description

Technical Field

[0001] This utility model relates to the field of photolysis purifiers, specifically a UV photolysis purifier capable of pre-treating waste gas. Background Technology

[0002] UV photolysis exhaust gas purifiers utilize high-energy UV ultraviolet light beams to decompose oxygen molecules in the air, producing free oxygen (i.e., active oxygen). Because the free oxygen carries an imbalance of positive and negative electrons, it needs to combine with oxygen molecules to produce ozone. Ozone has strong oxidizing properties. Through the synergistic photolysis and oxidation of organic waste gas and odorous gas, ozone degrades and transforms organic waste gas and odorous gas substances into low-molecular-weight compounds, water, and carbon dioxide.

[0003] According to the published patent 202321526177.6, a UV photolysis purifier capable of pre-treating exhaust gas, it includes a housing. A UV lamp is fixedly connected to the top of the inner wall of the housing, a base is fixedly connected to the bottom of the housing, and a shell is fixedly connected to one end of the housing. Through the cooperation of the housing, UV lamp, exhaust pipe, inlet pipe, shell, square box, filter plate, straight block, base, block, activated carbon plate, insert plate, and filter structure, water is sprayed out through pre-set nozzles on the curved pipe. The water spray removes dust from the exhaust gas. Simultaneously, the exhaust gas undergoes secondary filtration through the filter screen, achieving pre-treatment of the exhaust gas. The water containing dust falls onto the filter plate, which blocks the dust. Pulling the crossbar to the left moves the scraper to the left, further scraping away the dust, achieving secondary filtration, improving the dust treatment effect, preventing dust from being missed, and simplifying the cleaning of the filter plate.

[0004] However, in practice, traditional UV photolysis purifiers for waste gas pretreatment use fixed-position nozzles for spraying. Because the spraying area is limited and the waste gas enters different parts of the chamber, some waste gas fails to fully contact the spray nozzles, affecting the pretreatment effect. Furthermore, the multiple UV lamps stacked together can block each other's light sources, impacting their waste gas purification efficiency. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a UV photolysis purifier for pre-treating waste gas. This solves the problem that current traditional UV photolysis purifiers for pre-treating waste gas use fixed-position nozzles for spraying. Due to the limited spraying area, the waste gas enters different positions in the chamber, resulting in some waste gas not being able to fully contact the spray, thus affecting the pre-treatment effect. Furthermore, the multiple UV lamps stacked together cause mutual obstruction of the light sources between the fixed-position UV lamps, affecting the UV lamps' ability to purify waste gas.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a UV photolysis purifier for pre-treating waste gas is designed, including a purification box, a water tank installed at the bottom of the purification box, the top of the water tank having an open structure, a filter screen installed at the bottom of the water tank, water pumps installed on both sides of the top of the filter screen, a water pump connected to the bottom of the water pump, the bottom of the water pump passing through the filter screen and extending into the water tank, and a rotating spray assembly provided on the top of the water pump.

[0007] Preferably, the rotary spray assembly includes a first connecting pipe, a rotary joint, a second connecting pipe, a spray pipe, a nozzle, a first gear, a second gear, a rotating cylinder, and a motor.

[0008] Preferably, the first connecting pipe is connected to the top of the water pump, and a rotary joint is rotatably connected to the top of the first connecting pipe. A second connecting pipe is fixedly connected to the top of the rotary joint. The top of the second connecting pipe is a sealed structure. Multiple spray pipes are connected to the side of the second connecting pipe, and multiple nozzles are connected to the surface of the multiple spray pipes. The end of the spray pipe away from the second connecting pipe is a sealed structure.

[0009] Preferably, a first gear passes through the outside of the rotary joint, and the first gear is fixed to the position of the rotary joint. A second gear meshes with one side of the first gear, and a rotating cylinder is fixed to the top of the second gear. A motor is connected to the top of the rotating cylinder through the purification chamber, and the motor is installed on the top of the purification chamber.

[0010] Preferably, multiple UV lamps are installed on both sides of the rotating cylinder, and a battery is installed inside the rotating cylinder. The battery surface is provided with a charging port, which is arranged to correspond to the opening on the surface of the rotating cylinder.

[0011] Preferably, the top of both sides of the purification chamber is connected to an air inlet pipe and an air outlet pipe, respectively, and a control host is installed at the bottom of the side of the purification chamber.

[0012] Preferably, the front end of the purification chamber has an installation hole, a cover plate is installed inside the installation hole, and casters are installed at the four corners of the bottom of the purification chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the combination of a water pump, a water suction pipe, and a rotary spray assembly, not only allows water to be directly drawn from inside the tank for spraying, but also ensures that the sprayed water is directly filtered and then returned to the water tank, eliminating the need for multiple water pumps and circulation pipes. Furthermore, the rotary spray assembly enables the sprayed water to rotate and spray during the spraying process, thus ensuring sufficient contact with the exhaust gas at different locations, improving the exhaust gas treatment effect. Moreover, with multiple spray points, simultaneous rotary spraying from different locations ensures that the exhaust gas, after the first rotary spray, undergoes further treatment. The UV lamps purify the air, followed by a second round of rotating spraying. This multi-stage rotating spraying further enhances the exhaust gas treatment effect. Furthermore, a single drive motor can complete the rotating spraying at both positions, eliminating the need for multiple drive devices. This solves the technical problem of traditional UV photolysis purifiers for exhaust gas pretreatment, which use fixed-position nozzles for pre-spraying. Because the spraying area is limited and exhaust gas enters different parts of the chamber, some exhaust gas fails to fully contact the spray, affecting the pretreatment effect.

[0015] 2. This utility model combines a UV lamp body, a rotating cylinder, and a battery. The battery can power multiple UV lamp bodies on the surface of the rotating cylinder. When the motor drives multiple spray tubes to rotate and spray, it will simultaneously drive the rotating cylinder. Since multiple UV lamp bodies are set on the surface of the rotating cylinder, multiple UV lamp bodies can be driven to rotate at the same time. The multiple UV lamp bodies rotate and emit light sources, actively contacting and purifying the exhaust gas at different locations. This solves the technical problem that when multiple UV lamp tubes are stacked together, the light sources between the multiple UV lamp tubes will block each other, affecting the purification effect of the UV lamp tubes on the exhaust gas.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A UV photolysis purifier capable of pre-treating exhaust gas, see [link to example]. Figures 1 to 3The system includes a purification chamber 1, with a water tank 201 installed at the bottom inside. The top of the water tank 201 has an open structure, and a filter screen 202 is installed at the bottom of the water tank 201. Water pumps 203 are installed on both sides of the top of the filter screen 202, and a water suction pipe 210 is connected to the bottom of the water pump 203. The bottom of the water suction pipe 210 passes through the filter screen 202 and extends into the water tank 201. A rotating spray assembly is installed on the top of the water pump 203. The air inlet pipe 103 is first connected to an external exhaust gas pipe, allowing exhaust gas to enter the chamber through the air inlet pipe 103. Next, motor 2 is started, which drives the rotating drum 211 to rotate. The rotating drum 211 drives the second gear 212, which in turn drives the first gear 206 meshing on both sides to rotate. This, in turn, drives multiple rotary joints 205 to rotate. The multiple rotary joints 205 drive the second connecting pipe 207 and the spray pipe 208 at the top to rotate. During the rotation of the spray pipe 208, the water pump 203 is turned on. The water pump 203 pumps water from the water tank 201 into the first connecting pipe 204 and the second connecting pipe 207 through the water suction pipe 210. The water then enters the spray pipe 208 and is sprayed by multiple rotating nozzles 209 on its surface. The water from the rotating spray comes into contact with the exhaust gas in the water tank 201, reducing dust in the exhaust gas. After treatment, the water falls off and passes through the filter screen 202 to remove dust and impurities before re-entering the water tank 201, thus achieving repeated spraying treatment. Because multiple rotating joints 205 are simultaneously rotated, the exhaust gas, after the first rotary spray and purification by UV lamps, can be sprayed again on the other side. Rotary spraying is performed, and multiple rotational sprays further improve the effect of waste gas treatment. At the same time, a single drive motor 2 can complete the rotational spraying in two positions, eliminating the need for multiple drive devices. This solves the technical problem of traditional UV photolysis purifiers that can pre-treat waste gas. When pre-spraying waste gas, fixed-position nozzles 209 are used for spraying. Due to the limited spraying position and the fact that waste gas enters different positions in the chamber, some waste gas cannot fully contact the spray, which affects the pre-treatment effect of waste gas.

[0022] For details, see Figure 2 The rotary spray assembly includes a first connecting pipe 204, a rotary joint 205, a second connecting pipe 207, a spray pipe 208, a nozzle 209, a first gear 206, a second gear 212, a rotating cylinder 211, and a motor 2.

[0023] Further, see Figure 2The first connecting pipe 204 is connected to the top of the water pump 203. A rotary joint 205 is rotatably connected to the top of the first connecting pipe 204. A second connecting pipe 207 is fixedly connected to the top of the rotary joint 205. The top of the second connecting pipe 207 is a sealed structure. Multiple spray pipes 208 are connected to the side of the second connecting pipe 207. Multiple nozzles 209 are connected to the surface of the multiple spray pipes 208. The end of the spray pipe 208 away from the second connecting pipe 207 is a sealed structure.

[0024] It is worth noting that, see Figure 2 A first gear 206 passes through the outside of the rotary joint 205, and the first gear 206 and the rotary joint 205 are fixed in the same position. A second gear 212 meshes with one side of the first gear 206. A rotating cylinder 211 is fixed to the top of the second gear 212. A motor 2 is connected to the top of the rotating cylinder 211 through the purification box 1. The motor 2 is installed on the top of the purification box 1.

[0025] It is worth noting that, see Figure 2 Multiple UV lamps 3 are installed on both sides of the rotating cylinder 211. A battery 301 is installed inside the rotating cylinder 211. A charging port 302 is provided on the surface of the battery 301, and the charging port 302 is set to correspond to the opening on the surface of the rotating cylinder 211. During the rotation of the rotating cylinder 211, it will also drive the multiple external UV lamps 3 to rotate. The multiple UV lamps 3 emit light by rotating, actively contacting and purifying the exhaust gas at different positions, thus improving the purification effect. At the same time, since the multiple UV lamps 3 are powered by the battery 301 inside the rotating cylinder 211, they are not constrained by the circuit. This solves the technical problem that when multiple UV lamps are stacked together, the light source between multiple fixed-position UV lamps will block each other, affecting the purification effect of the UV lamps on the exhaust gas.

[0026] It is worth mentioning that, see Figure 1 The top of both sides of the purification chamber 1 is connected to an air inlet pipe 103 and an air outlet pipe 104, respectively, and a control host 105 is installed on the bottom side of the purification chamber 1.

[0027] It is worth emphasizing that, see Figure 1 The front end of the purification chamber 1 has an installation hole 101, and a cover plate 102 is installed inside the installation hole 101. All four corners of the bottom of the purification chamber 1 are equipped with casters 106.

[0028] When using a UV photolysis purifier capable of pre-treating exhaust gas, first connect the inlet pipe 103 to an external exhaust gas pipe, allowing the exhaust gas to enter the housing through the inlet pipe 103. Then, start the motor 2, which drives the rotating drum 211 to rotate. The rotating drum 211 drives the second gear 212, which in turn drives the first gear 206 meshing on both sides to rotate, thereby driving multiple rotating joints 205 to rotate. The multiple rotating joints 205 drive the second connecting pipe 207 and the spray pipe 208 at the top to rotate. During the rotation of the spray pipe 208, the water pump 203 is turned on. The water pump 203 draws water from the water tank 201 through the water suction pipe 210 into the first connecting pipe 204 and the second connecting pipe 207, thus entering the spray pipe 208. The water is then sprayed in a rotating manner through multiple nozzles 209 on the surface of the spray pipe 208, and the rotating sprayed water comes into contact with the exhaust gas in the water tank 201. The system performs dust suppression on the exhaust gas, and the treated water falls off and passes through the filter screen 202 to remove dust and impurities before re-entering the water tank 201. This achieves repeated spraying treatment. Since multiple rotary joints 205 rotate simultaneously, the exhaust gas is purified by UV lamps after the first rotary spray and can then undergo another rotary spray on the other side. Multiple rotary sprays further improve the exhaust gas treatment effect. At the same time, a single drive motor 2 can complete the rotary spraying at two positions, eliminating the need for multiple drive devices. During the rotation of the rotating cylinder 211, multiple external UV lamps 3 also rotate. The multiple UV lamps 3 emit light and actively contact the exhaust gas at different positions for purification, improving the purification effect. Furthermore, since the multiple UV lamps 3 are powered by the battery 301 inside the rotating cylinder 211, they are not constrained by wiring.
