Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to an energy-saving purification device for exhaust gas from kitchen waste treatment equipment. Background Technology

[0002] Food waste generated by the catering industry and centralized waste treatment plants releases a large amount of malodorous exhaust gas during fermentation and treatment. The main components are hydrogen sulfide, ammonia and volatile organic compounds. If directly discharged, it will have a serious impact on the surrounding environment and residents' health. Therefore, it is of great significance to study the exhaust gas purification device that is matched with food waste treatment equipment.

[0003] Existing purification devices face specific challenges when treating kitchen waste exhaust gas, which typically has high humidity, high oil mist content, and a certain degree of corrosivity. Existing purification technologies, such as photolysis oxidation or activated carbon adsorption, have shortcomings in application. Water vapor and oil mist in the exhaust gas easily adhere to the surface of the photolysis lamp tube, hindering the efficiency of ultraviolet lamp irradiation, or clogging the micropores of activated carbon, causing the purification components to fail rapidly, requiring frequent maintenance and replacement, and increasing operating costs.

[0004] In addition, some purification devices have a relatively simple process design, which may rely solely on adsorption or photolysis, resulting in incomplete purification of complex waste gas components. In particular, they cannot effectively capture some trace amounts of pollutants that have not been completely decomposed. The purified gas may still carry odors, making it difficult to meet strict emission standards and affecting the purification effect.

[0005] On the other hand, traditional exhaust gas purification devices, especially core components such as lamps, fans and air pumps that need to run for a long time, usually rely on the power grid for continuous power supply, resulting in high overall energy consumption of the device. Furthermore, they lack a mechanism to adjust the operating status according to the exhaust gas concentration or treatment period, causing unnecessary energy waste, which is not in line with the development trend of energy conservation and environmental protection.

[0006] Therefore, this utility model proposes an energy-saving purification device for exhaust gas from kitchen waste treatment equipment to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems existing in the energy-saving purification device for exhaust gas of kitchen waste treatment equipment, such as insufficient pretreatment of water vapor and oil mist in exhaust gas leading to easy failure of purification components, incomplete purification resulting in odor residue, and high energy consumption during device operation, this utility model aims to provide an energy-saving purification device for exhaust gas of kitchen waste treatment equipment with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an energy-saving purification device for exhaust gas from a kitchen waste treatment equipment, comprising: a photolysis reactor and an exhaust gas inlet connected to the photolysis reactor; as well as a primary filter, an air pump, a quartz column, an activated carbon material plate, a lamp tube, an exhaust pipe, a gas collection tank, an activated carbon adsorption layer, a motor, a fan, a circuit pipe, a solar panel, a connector, a pressure device, and a time controller.

An activated carbon material plate is fixedly connected to the left side of the photolysis reactor, and a lamp tube is fixedly connected to the inner left wall of the photolysis reactor. An air outlet pipe is fixedly connected to the front side of the photolysis reactor. The air outlet pipe enters the inner cavity of the gas collection tank. An activated carbon adsorption layer is fixedly installed on the top of the gas collection tank. A motor and a fan driven by the motor are installed inside the gas collection tank. The photolysis reactor is fixedly connected to the solar panel through a circuit pipe. A pressure device is fixedly connected to the top of the photolysis reactor through a connector. A time controller is also fixedly connected to the top of the photolysis reactor.

[0010] Preferably, the primary filter is used to filter large particulate pollutants; the quartz column is used to isolate water vapor, oil mist and corrosive components in the exhaust gas.

[0011] Preferably, the activated carbon material plate is used for physical adsorption of waste gas before it enters the photolysis reactor.

[0012] Preferably, the lamp is used to emit ultraviolet light of a specific wavelength to decompose pollutants in the exhaust gas.

[0013] Preferably, the solar panel provides energy to the photolysis reactor and the lamp tube through the circuit tube.

[0014] Preferably, the pressure gauge is used to monitor and display the exhaust gas pressure inside the photolysis reactor; the time controller is used to set the working duration of the lamp tube according to the photolysis reaction requirements.

[0015] Preferably, the outlet end of the air duct extends into the inner cavity of the gas collection tank and is located below the activated carbon adsorption layer.

[0016] Preferably, the fan is located below the activated carbon adsorption layer to generate an upward guiding effect, allowing the gas to pass through the activated carbon adsorption layer; the activated carbon adsorption layer is used for secondary treatment of the purified gas.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model pre-treats the waste gas through a multi-stage process by setting up a primary filter, quartz column and activated carbon material plate, then decomposes it through a photolysis reactor, and finally purifies and guides it out through a fan and activated carbon adsorption layer in the gas collection tank. This solves the problem in the prior art that the pre-treatment of water vapor, oil mist and corrosive components in kitchen waste waste gas is insufficient, which leads to easy failure of subsequent photolysis and adsorption components, incomplete purification and residual odor.

[0019] 2. This utility model solves the problems of existing purification devices that rely entirely on the power grid, have high energy consumption, and waste energy by idling during unnecessary periods, by setting up solar panels to provide energy for the photolysis reactor and lamps, and by setting up a time controller to set the working time of the lamps.

[0031] Meanwhile, an activated carbon material plate 6 is fixedly connected to the left side of the photolysis reactor 1.

[0039] Working Principle: When the user performs waste gas treatment, the waste gas first enters the energy-saving purification device of the kitchen waste treatment equipment through the waste gas inlet 7. The primary filter 9, which is fixedly connected to the left end of the waste gas inlet 7, performs the first filtration of large particulate pollutants during the intake. An air pump 10 is fixedly connected to the middle part of the waste gas inlet 7 and the primary filter 9. When the waste gas has difficulty entering the device, the air pump 10 can draw in the gas. A quartz column 8 is fixedly connected to the right wall of the air pump 10. The quartz column 8 allows the gas to be filtered by the primary filter 9 and isolating water vapor, oil mist, and corrosive components in the waste gas. After the waste gas is initially treated on the left side of the photolysis reactor 1, it enters the activated carbon material plate 6 fixedly connected to the left side of the reactor 1 through the waste gas inlet 7. At this time, the activated carbon material plate 6 physically adsorbs the waste gas, adsorbing pollutant molecules within its pores, thus separating the gas from the pollutants. After treatment, the waste gas enters the photolysis reactor 1. A lamp tube 2 is fixedly connected to the inner wall of the left side of the reactor 1. The lamp tube 2 emits ultraviolet light of a specific wavelength to decompose pollutants in the waste gas. A pressure device 4 is fixedly connected to the top of the reactor 1 via a connector 3. Device 4 is used to monitor whether the exhaust gas in the photolysis reactor 1 is overloaded. A time controller 5 is fixedly connected to the top of the photolysis reactor 1. The time controller 5 allows the user to set the working time of the lamp tube 2 according to the specific photolysis reaction requirements. When the set time is reached, the time controller 5 will send a signal to control the light source to turn off or perform related operations. The photolysis reactor 1 is fixedly connected to the solar panel 12 through the circuit pipe 11. The solar panel 12 realizes the energy transmission to the photolysis reactor 1 and the lamp tube 2. After purification, the gas will enter the gas collection tank 15 from the air outlet pipe 13 fixedly connected to the front of the photolysis reactor 1. Inside the cavity, the motor 14 is started, and the fan 17 driven by the motor 14 rotates to guide the air upward. An activated carbon adsorption layer 16 is fixedly installed on the top of the gas collection tank 15. The activated carbon adsorption layer 16 is used for secondary treatment of the purified gas, purifying the gas containing trace amounts of undecomposed pollutants. Finally, the gas is discharged upward to reduce ground odor. The kitchen waste treatment equipment exhaust gas energy-saving purification device effectively solves the problem of water and gasoline mist damage to the core components through three-stage pretreatment of primary filter 9, quartz column 8 and activated carbon material plate 6, and achieves the energy-saving goal of device operation by using solar panel 12.
