Description

Technical Field

[0001] This utility model relates to the field of gas treatment technology, and in particular to a device for collecting and disposing of VOCs gas from UV inks. Background Technology

[0002] UV inks generate a large amount of volatile organic compounds (VOCs) during curing and other processes. These VOCs not only have an irritating odor and pose serious health risks to workers in the workshop, such as causing respiratory illnesses, eye irritation, headaches, and dizziness, but long-term exposure may also increase the risk of serious diseases such as cancer. Moreover, after VOCs are released into the atmosphere, they participate in photochemical reactions to generate pollutants such as ozone and secondary organic aerosols, which in turn lead to a decline in air quality, the formation of smog and other severe weather, and negatively impact the ecological environment and climate.

[0003] Currently, although some VOCs gas treatment devices exist on the market, some devices have relatively simple structures and single functions, using only a single adsorption method to treat VOCs gases, such as relying solely on activated carbon adsorption. This method is not thorough enough in treating VOCs gases and is difficult to remove multiple harmful components from the gas, resulting in the treated gas still containing high concentrations of pollutants, failing to meet strict environmental emission requirements. In addition, some devices consume a lot of water resources during the treatment process, failing to achieve water recycling, resulting in water waste and increased treatment costs. Therefore, we are introducing a new device for collecting and treating VOCs gases from UV inks. Utility Model Content

[0004] The main objective of this invention is to provide a device for collecting and disposing of VOCs gas from UV inks, which can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for collecting and disposing of VOCs gas from UV inks includes a spray tank and a purification chamber. A first mounting bracket is fixedly connected to the lower rear part of the outer surface of the spray tank. A spraying mechanism is fixedly installed on the upper end of the first mounting bracket. An air inlet pipe is fixedly connected to the middle left part of the outer surface of the spray tank. A first valve is installed on the air inlet pipe. A filter screen is installed in the lower part of the spray tank. A purification mechanism is fixedly connected to the middle part of the purification chamber. A sealing door is installed at the front end of the purification chamber. A connecting pipe is fixedly connected to the middle left end of the purification chamber and the middle upper end of the spray tank. An air outlet pipe is fixedly connected to the middle right end of the purification chamber. A fan is fixedly installed on the right end of the air outlet pipe. An exhaust pipe is fixedly installed at the output end of the fan. A second mounting bracket is fixedly connected to the lower outer surface of the fan.

[0006] Preferably, the spraying mechanism includes a water pump, an input pipe is fixedly connected to the input end of the water pump, an output pipe is fixedly connected to the output end of the water pump, a spray pipe is fixedly connected to the end of the output pipe away from the water pump, support blocks are fixedly connected to the front, rear and right sides of the outer surface of the spray pipe, an inlet pipe is fixedly connected to the left side of the outer surface of the spray pipe, a second valve is provided on the inlet pipe, and several nozzles are fixedly installed on the lower part of the outer surface of the spray pipe.

[0007] Preferably, the water pump is fixedly installed on the upper end of the first mounting bracket, and the input pipe is inserted and fixedly connected to the rear of the spray tank.

[0008] By adopting the above technical solution, the input pipe is inserted and fixedly connected to the rear of the spray tank, so that one end of the input pipe can extend to the lower part of the spray tank, ensuring that the water pump can stably draw the filtered clean water, providing a key water conveyance path for water resource recycling.

[0009] Preferably, the spray pipe is fixedly connected to the inner wall of the spray tank by three support blocks, and the spray pipe is located in the upper part of the spray tank.

[0010] By adopting the above technical solution, three support blocks are fixed to the front, rear and right sides of the spray pipe respectively, and connected to the inner wall of the spray tank to ensure the stability of the spray pipe.

[0011] Preferably, the water inlet pipe is fixedly connected to the spray tank, and several spray nozzles are arranged in a ring array below the spray pipe.

[0012] By adopting the above technical solution, several nozzles are arranged in a ring array, which can make the water flow form a ring spray area, ensuring that the VOCs gas entering the spray tank can fully contact the water flow.

[0013] Preferably, the purification mechanism includes a connecting seat, the front end of which has two engaging grooves, each engaging with an activated carbon adsorption plate, and the front center of each of the two activated carbon adsorption plates has a threaded hole. The left and right ends of the connecting seat each have several ventilation holes.

[0014] Preferably, the connecting seat is fixedly installed in the middle of the purification box, the two locking slots are internally connected, and the two activated carbon adsorption plates have the same structure.

[0015] By adopting the above technical solution, the two locking slots are internally connected to form a continuous gas channel, allowing the gas to pass through the two activated carbon adsorption plates in sequence. Through dual adsorption, residual VOCs and harmful impurities in the gas are intercepted, ensuring that the emitted gas meets the standards.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The system connects to an external water source via an inlet pipe and controls the water intake with a second valve, allowing water to be smoothly delivered to the spray pipe and evenly sprayed out through multiple nozzles below. The water mist sprayed from the multiple nozzles can fully contact the VOCs gas generated by the UV ink, and perform preliminary treatment of the VOCs gas through physical adsorption and dissolution, which helps to improve the overall VOCs gas collection and treatment efficiency. At the same time, the water containing impurities after spraying can be effectively filtered through a filter screen to remove pollutants or impurities from the water. The filtered clean water is stored at the bottom of the spray tank and then pumped back into the spray pipe for continued spraying operations, so that water resources can be recycled and water resources can be avoided. 2. After preliminary treatment, the VOCs gas enters the purification chamber through the connecting pipe. The two activated carbon adsorption plates can exert the strong adsorption performance of activated carbon, and through dual adsorption, they can efficiently adsorb and retain the residual VOCs and other harmful impurities in the gas, reducing the content of harmful substances in the gas. The gas after adsorption treatment is then extracted by the fan and discharged through the exhaust pipe, which can ensure that the discharged gas meets the requirements of pollution-free or environmental protection emission standards, reducing the damage to the surrounding ecological environment. When the activated carbon adsorption plate is saturated and the adsorption efficiency decreases, it can be replaced simply by opening the sealed door, screwing the bolt into the threaded hole, and pulling out the activated carbon adsorption plate.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A device for collecting and disposing of VOCs gas from UV inks includes a spray tank 1 and a purification chamber 2. A first mounting bracket 3 is fixedly connected to the lower rear part of the outer surface of the spray tank 1. A spraying mechanism 4 is fixedly installed on the upper end of the first mounting bracket 3. An air inlet pipe 5 is fixedly connected to the middle left part of the outer surface of the spray tank 1. A first valve 6 is installed on the air inlet pipe 5. A filter screen 7 is installed in the lower part of the inner surface of the spray tank 1. A purification mechanism 8 is fixedly connected to the middle inside the purification chamber 2. A sealing door 9 is installed at the front end of the purification chamber 2. A connecting pipe 10 is fixedly connected to the middle left end of the purification chamber 2 and the middle upper end of the spray tank 1. An air outlet pipe 11 is fixedly connected to the middle right end of the purification chamber 2. A fan 12 is fixedly installed on the right end of the air outlet pipe 11. An exhaust pipe 13 is fixedly installed at the output end of the fan 12. A second mounting bracket 14 is fixedly connected to the lower outer surface of the fan 12.

[0023] In this embodiment, the spraying mechanism 4 includes a water pump 41. The input end of the water pump 41 is fixedly connected to an input pipe 42, and the output end of the water pump 41 is fixedly connected to an output pipe 43. The end of the output pipe 43 away from the water pump 41 is fixedly connected to a spray pipe 44. Support blocks 45 are fixedly connected to the front, rear, and right sides of the outer surface of the spray pipe 44. An inlet pipe 46 is fixedly connected to the left side of the outer surface of the spray pipe 44. A second valve 47 is provided on the inlet pipe 46. Several nozzles 48 are fixedly installed on the lower part of the outer surface of the spray pipe 44. The water pump 41 is fixedly installed on the upper end of the first mounting bracket 3. The input pipe 42 is inserted and fixedly connected to the rear of the spray tank 1. The spray pipe 44 is fixedly connected to the inner wall of the spray tank 1 through three support blocks 45, and the spray pipe 44 is located in the upper part of the spray tank 1. The inlet pipe 46 is inserted and fixedly connected to the spray tank 1. Several nozzles 48 are arranged in a ring array below the spray pipe 44.

[0024] Through the above scheme: the water inlet pipe 46 is connected to an external water source and the water inlet is controlled by the second valve 47, so that the water can be smoothly delivered to the spray pipe 44 and sprayed evenly through multiple nozzles 48 below. The water sprayed from the multiple nozzles 48 can fully contact the VOCs gas generated by the UV ink, and perform preliminary treatment of the VOCs gas through physical adsorption, dissolution and other effects, which helps to improve the overall VOCs gas collection and treatment efficiency. At the same time, the water containing impurities after spraying can be effectively filtered through the filter screen 7 to remove pollutants or impurities in the water. The filtered clean water is stored at the bottom of the spray tank 1 and then pumped back into the spray pipe 44 by the water pump 41 for continued use in the spraying operation, so that water resources can be recycled and water resources can be avoided.

[0025] In this embodiment, the purification mechanism 8 includes a connecting seat 81. The front end of the connecting seat 81 has two engaging grooves 82, and activated carbon adsorption plates 83 are engaged and connected in both engaging grooves 82. The front middle of both activated carbon adsorption plates 83 is provided with threaded holes 84. The left and right ends of the connecting seat 81 are provided with several ventilation holes 85. The connecting seat 81 is fixedly installed in the middle of the purification box 2. The two engaging grooves 82 are internally connected, and the two activated carbon adsorption plates 83 have the same structure.

[0026] Through the above scheme: after the VOCs gas has been pre-treated, it enters the purification chamber 2 through the connecting pipe 10. The two activated carbon adsorption plates 83 can exert the strong adsorption performance of activated carbon, and through dual adsorption, the residual VOCs components and other harmful impurities in the gas are efficiently adsorbed and intercepted, reducing the content of harmful substances in the gas. The gas after adsorption treatment is then extracted by the fan 12 and discharged through the exhaust pipe 13, which can ensure that the discharged gas meets the requirements of pollution-free or environmental protection emission standards, reducing the damage to the surrounding ecological environment. When the activated carbon adsorption plate 83 is saturated and the adsorption efficiency decreases, it can be replaced simply by opening the sealing door 9, screwing the bolt into the threaded hole 84 and pulling out the activated carbon adsorption plate 83.

[0027] It should be noted that this utility model is a device for collecting and disposing of VOCs gas from UV ink. During use, the first valve 6 on the inlet pipe 5 is opened to introduce the VOCs gas generated by the UV ink into the spray tank 1 through the inlet pipe 5. At the same time, the water pump 41 on the first mounting bracket 3 is started. The water pump 41 draws the clean water stored at the bottom of the spray tank 1 through the input pipe 42. The clean water is delivered to the spray pipe 44 fixed in the upper part of the spray tank 1 through the output pipe 43. If the water level in the spray tank 1 is insufficient, the water inlet pipe can be opened. The second valve 47 on the spray pipe 46 supplies external water to the spray pipe 44 through the inlet pipe 46. Subsequently, several nozzles 48 arranged in a ring below the spray pipe 44 spray water evenly, forming a ring-shaped spray area. This allows the VOCs gas entering the spray tank 1 to fully contact the sprayed water mist, performing preliminary treatment of the VOCs gas through physical adsorption and dissolution, removing some harmful components. After preliminary treatment, the water containing impurities flows down to the lower part of the spray tank 1, where it is filtered by the filter screen 7 to remove pollutants and impurities. The filtered clean water is stored back at the bottom of the spray tank 1 to achieve water resource recycling and avoid waste. The VOCs gas that has completed the preliminary treatment flows upward and enters the purification tank 2 through the connecting pipe 10 between the spray tank 1 and the purification tank 2. The two activated carbon adsorption plates 83 engaged in the connecting seat 81 in the middle of the purification tank 2 play their role. The gas passes through the two activated carbon adsorption plates 83 in sequence. Utilizing the strong adsorption performance of activated carbon, the gas is doubly adsorbed and intercepted to remove residual VOCs and harmful impurities, further purifying the gas. Finally, the fan 12 on the second mounting bracket 14 is started. The fan 12 draws the purified gas through the air outlet pipe 11 at the right end of the purification tank 2, and then discharges the qualified and pollution-free gas through the exhaust pipe 13 at the output end of the fan 12, realizing the efficient collection and treatment of UV ink VOCs gas. When the activated carbon adsorption plate 83 becomes saturated and the purification efficiency decreases, the sealing door 9 at the front end of the purification tank 2 can be opened, and the activated carbon adsorption plate 83 can be pulled out and replaced by screwing the external bolt into the threaded hole 84 to ensure the continuous and stable operation of the device.
