Technical Field

[0001] The present invention relates to the technical field related to environmental protection equipment, and in particular to a skid-mounted integrated landfill odor treatment device and method. Background Art

[0002] In the landfill ecological restoration project, especially during the landfill excavation process, a variety of malodorous gases will be produced, mainly including ammonia (NH3), hydrogen sulfide (H2S), dimethyl sulfide (C2H6S), dimethyl disulfide (C2H6S2), etc. These malodorous gases pose a threat to the environment and human health. Therefore, effective control measures need to be taken to reduce or control the emission and spread of malodorous gases.

[0003] Due to the frequent activity of anaerobic microorganisms in landfills, a large amount of oxygenated hydrocarbons and sulfides are released, and the concentration of odor-causing factors in the odor is high. The odor treatment effect of traditional landfill odor treatment devices cannot be effectively guaranteed; in addition, the current market mostly adopts a single equipment combination treatment process. This type of combined treatment system is composed of multiple devices connected by pipes, which is not only unsightly in appearance, but also has a large installation volume and occupies a large area; on the other hand, the odor treatment device of the landfill ecological restoration project has a short service life. After the restoration project is completed, in order to save costs, the odor treatment device is usually required to be transferred to other project sites for reuse. It needs to undergo multiple disassembly, transfer, and reinstallation. During this process, the system components are easily damaged.

[0004] Therefore, it is particularly important to invent a skid-mounted integrated landfill odor treatment method and device that can meet the needs of landfill odor treatment. Summary of the invention

After the reaction, the liquid gas is transferred from the high-efficiency absorption device to the gas-liquid separation device to separate the gas and water vapor. After the gas-liquid separation, the gas is transferred from the gas-liquid separation device to the high-efficiency adsorption device for gas adsorption. Finally, the gas is transferred from the high-efficiency adsorption device to the atomization deodorization device to complete the odor removal treatment. Finally, the purified gas is discharged through the main air outlet.

[0011] As a preferred technical solution of the present invention, the atomization deodorization device includes an atomization deodorization air inlet area, an atomization main machine, an atomization spray pipeline, and an atomization deodorization air outlet area; The atomization main machine is connected with the atomization spray pipeline; The atomization deodorization air inlet area is communicated with the adsorption air outlet area, and the atomization deodorization air outlet area is communicated with the total air outlet.

[0012] As a preferred technical solution of the present invention, the high-efficiency absorption device, the gas-liquid separation device, the high-efficiency adsorption device, and the atomization deodorization device are arranged in a "field" shape structure and are provided with a skid-mounted steel structure on the outside.

[0013] As a preferred technical solution of the present invention, a chemical dosing device is arranged on the outside of the circulation water tank. The total air outlet is connected with an induced draft fan through a connecting air duct. One end of the induced draft fan is provided with a discharge air duct. The chemical dosing device and the induced draft fan are respectively electrically connected with an electric control system.

[0014] As a preferred technical solution of the present invention, the odor treatment device is arranged on a vehicle, and a solar panel is fixedly arranged at the upper end of the skid-mounted steel structure. The solar panel is electrically connected to the electric control system, the chemical dosing device, and the induced draft fan respectively.

[0015] The present invention also provides a method for treating landfill odor, which includes the following steps: Step 1, send the odor generated by the landfill into the interior of the high-efficiency absorption device along the total air inlet. Step 2, the odor enters the absorption packing layer. At the same time, the spray pump pumps the chemical agent from the circulation water tank to the spray pipeline. The chemical agent is atomized and sprayed into the absorption packing layer from the spray pipeline and makes full contact with the odor. The liquid-phase gas passing through the absorption packing layer enters the demisting packing layer and initially intercepts the droplets in the liquid-phase gas. Finally, the liquid-phase gas is discharged from the absorption air outlet area. Step 3, the liquid-phase gas enters the interior of the gas-liquid separation air inlet area from the absorption air outlet area, and sequentially passes through the primary filter module 1, the primary filter module 2, the medium-high efficiency filter module 1, and the medium-high efficiency filter module 2 to complete the removal of water vapor. The gas after removing water vapor is discharged from the gas-liquid separation air outlet area. Step 4, the gas enters the interior of the adsorption air inlet area from the gas-liquid separation air outlet area, and further adsorption work is completed at the high-efficiency adsorption layer. The gas after completing the adsorption work is discharged from the adsorption air outlet area. Step 5, the gas enters the atomized deodorization air inlet area from the adsorption air outlet area. Subsequently, the atomization host controls the atomized spray pipeline to work and atomizes and sprays the deodorant liquid. The atomized deodorant liquid makes full contact with the gas and completes the final deodorization treatment of the gas. Finally, the purified gas is discharged through the total air outlet.

[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] Embodiment 1 like Figure 1-Figure 12 As shown, the skid-mounted integrated landfill odor treatment device comprises a high-efficiency absorption device 2, a gas-liquid separation device 3, a high-efficiency adsorption device 4 and an atomization deodorization device 5 which are connected in sequence, and the four devices are connected to each other in sequence, so that the odor can pass through the four treatment devices in sequence; The odor enters the high-efficiency absorption device 2 from the main air inlet 1 and reacts with the deodorizing agent for preliminary deodorization. The liquid gas after the reaction is transferred from the high-efficiency absorption device 2 to the gas-liquid separation device 3 to separate the gas and water vapor. After the gas-liquid separation is completed, the gas is transferred from the gas-liquid separation device 3 to the high-efficiency adsorption device 4 for gas adsorption. Finally, the gas is transferred from the high-efficiency adsorption device 4 to the atomization deodorization device 5 to complete the deodorization treatment. Finally, the purified gas is discharged through the main air outlet 6.

[0036] It should be noted that the odor concentration after treatment by the odor treatment device of the present invention is between 100-200 (dimensionless, organized detection), which is far lower than the odor concentration emission limit of 2000 (dimensionless) proposed in the "Emission Standard of Odor Pollutants" (GB14554-93).

[0037] Further, if Figure 3-Figure 4As shown, the high-efficiency absorption device 2 includes an absorption air inlet area 201, an absorption filler layer 202, a demisting filler layer 203, a circulating water tank 204, a spray pump 205, a spray pipe 206 and an absorption air outlet area 207, the absorption air inlet area 201 is connected to the total air inlet 1; the absorption filler layer 202 and the demisting filler layer 203 are arranged in sequence along the gas flow direction; the circulating water tank 204 is arranged at the lower end of the absorption filler layer 202, the circulating water tank 204 is connected to the spray pipe 206 through the spray pump 205, and the spray pipe 206 is arranged at the upper end of the absorption filler layer 202; the absorption air outlet area 207 is arranged on one side of the demisting filler layer 203.

[0038] Among them, the malodorous gas enters the absorption air inlet area 201 through the main air inlet 1. Therefore, the main air inlet 1 is the starting point of the entire treatment. The malodorous gas first gathers in the absorption air inlet area 201 and is then guided to the absorption filler layer 202. Then the spray pump 205 pumps the agent from the circulating water tank 204 to the spray pipe 206. The agent is atomized and sprayed from the spray pipe 206 to the absorption filler layer 202 and fully contacts with the odor (the spray pipe 206 distributes the agent on the absorption filler layer 202 to form a uniform spray). The gas after the absorption reaction carries more droplets. The liquid phase gas passing through the absorption filler layer 202 will enter the demisting filler layer 203 and preliminarily intercept most of the droplets in the liquid phase gas. Finally, the liquid phase gas is discharged from the absorption air outlet area 207, and the agent dropped from the absorption filler layer 202 will return to the circulating water tank 204 and be recycled again.

[0039] It should be noted that the absorption filler layer 202 includes various types of fillers, such as Raschig rings, Pall rings, multi-faceted hollow balls, Q-PAC, etc., which provide a large surface area for contact and enhance the contact effect between the gas and the agent; The demisting filler layer 203 may be made of, but not limited to, Raschig rings, Pall rings, multi-faceted hollow balls, N-PAC and other fillers.

[0040] It should be noted that the agent used is a mixed solution of acid and oxidant in a ratio of 2:1; the alkali solution can be an acidic solution such as dilute sulfuric acid and citric acid, and the oxidant can be a solution such as sodium hypochlorite and hydrogen peroxide.

[0041] Further, if Figure 3As shown, the high-efficiency absorption device 2 also includes a spray inspection port 208 corresponding to the absorption filler layer 202 and a defogger inspection port 209 corresponding to the defogger inspection port 203. The operator can install and inspect the absorption filler layer 202, the spray pipe 206 or the defogger inspection port 203 inside the high-efficiency absorption device 2 by opening the spray inspection port 208 or the defogger inspection port 209. It should be noted that the spray inspection port 208 or the defogger inspection port 209 are both arranged on the side of the high-efficiency absorption device 2.

[0042] It should be noted that after being treated by the high-efficiency absorption device 2, more than 30% of the odor components can be removed.

[0043] Further, if Figure 5 As shown, the gas-liquid separation device 3 includes a gas-liquid separation air inlet area 301, a primary filter module 1 302, a primary filter module 2 303, a medium and high efficiency filter module 1 304, a medium and high efficiency filter module 2 305 and a gas-liquid separation air outlet area 306 which are arranged in sequence along the gas flow direction, and the gas-liquid separation air inlet area 301 is connected to the absorption air outlet area 207.

[0044] Among them, the gas-liquid separation device 3 is mainly used to further remove water vapor in the liquid phase gas. After the liquid phase gas passes through the primary filter module 1 302, the primary filter module 2 303, the medium and high efficiency filter module 1 304, and the medium and high efficiency filter module 2 305 in sequence, the water vapor removal rate can reach a minimum of more than 95%.

[0045] It should be noted that the primary filter module 1 302 and the primary filter module 2 303 respectively use G3 and G4 filtering accuracies to preliminarily remove large particles and some water vapor. The primary filter module 1 302 can use a primary air filter (usually using synthetic fiber materials or glass fibers) or a metal mesh filter (using a solid metal mesh material, which can be pre-filtered and adapted to a high air flow environment), with a filtering accuracy of 3 to 10 μm. The primary filter module 2 303 can use a synthetic fiber filter (mainly made of synthetic materials, suitable for removing finer dust and pollutants) or a paper filter (using high-efficiency paper materials, which can effectively filter most of the particles in the air without affecting the efficiency of the airflow), with a filtering accuracy of 1 to 3 μm. The medium and high efficiency filter module 1 304 and the medium and high efficiency filter module 2 305 are respectively set with F5 and F7 filtration precisions to enhance the removal of water vapor and small particles and ensure the effectiveness of subsequent adsorption. The medium and high efficiency filter module 1 304 and the medium and high efficiency filter module 2 305 can use filter modules made of nanofiber materials (with finer fibers and larger surface area, which can effectively capture tiny particles) or activated carbon composite materials (which can not only filter solid particles in the air, but also adsorb gases and odors). The filtration precision of the medium and high efficiency filter module 1 304 is 0.5~1μm, and the filtration precision of the medium and high efficiency filter module 2 305 is 0.3~0.5μm.

[0046] Optionally, a set of HEPA filters (with excellent protection against fine particles) can be added at the rear end of the medium and high efficiency filtration module 2 305 to further improve the adsorption effect. The filtration accuracy of the HEPA filter is less than 0.3μm. Since the subsequent adsorbent has high requirements for water vapor content, it is ultimately necessary to ensure that the 1-5μm water vapor removal rate of the gas after multi-stage filtration is not less than 95%, so as to facilitate the subsequent gas adsorption and deodorization work.

[0047] Further, if Figure 6-Figure 8 As shown, the high-efficiency adsorption device 4 includes an adsorption air inlet area 401 connected to the gas-liquid separation air outlet area 306, an adsorption air outlet area 403 arranged on one side of the adsorption air inlet area 401, and a high-efficiency adsorption layer 402 arranged between the adsorption air inlet area 401 and the adsorption air outlet area 403. After the gas enters the interior of the adsorption air inlet area 401 from the gas-liquid separation air outlet area 306, it will pass through the high-efficiency adsorption layer 402 and undergo further adsorption. The adsorbent in the high-efficiency adsorption layer 402 may be but is not limited to activated carbon, macroporous resin, SDG, etc. The adsorbent is mainly used to adsorb VOCs in the gas, and the gas after the adsorption work is completed is discharged from the adsorption air outlet area 403.

[0048] It should be noted that the installation method of the high-efficiency adsorption layer 402 is shown as horizontal installation in this figure, and vertical installation can also be adopted in actual implementation, and the number of layers can be adjusted according to the specific design; In addition, the high-efficiency adsorption layer 402 is provided with an inlet guide plate 404 in contact with the high-efficiency adsorption layer 402 at one end close to the adsorption air inlet area 401, and an outlet guide plate 405 in contact with the high-efficiency adsorption layer 402 is provided at one end close to the adsorption air outlet area 403. After entering the adsorption air inlet area 401, the air will quickly enter the interior of the high-efficiency adsorption layer 402 under the action of the inlet guide plate 404 and perform adsorption work, and finally be discharged to the adsorption air outlet area 403 under the limiting action of the outlet guide plate 405.

[0049] It should be noted that after being treated by the high-efficiency adsorption device 4, more than 50% of the odor components can be removed.

[0050] Further, as Fig. 9 shown, the atomizing deodorization device 5 includes an atomizing deodorization air inlet area 501, an atomizing main unit 502, an atomizing spray pipeline 503, and an atomizing deodorization air outlet area 504; The atomizing main unit 502 is connected to the atomizing spray pipeline 503; The atomizing deodorization air inlet area 501 communicates with the adsorption air outlet area 403, and the atomizing deodorization air outlet area 504 communicates with the total air outlet 6.

[0051] It should be noted that the atomizing main unit 502 adopts an integrated design, with a liquid storage tank and a deodorant liquid delivery pump inside. After the gas enters the atomizing deodorization air inlet area 501 from the adsorption air outlet area 403, the deodorant liquid delivery pump transports the deodorant liquid from the liquid storage tank to the atomizing spray pipeline 503, and the atomizing spray pipeline 503 atomizes and sprays the deodorant liquid inside the space of the atomizing deodorization device 5. The gas fully contacts and reacts with the extremely fine deodorant liquid droplets filling the entire space to eliminate its odor components, and finally the purified gas is discharged through the total air outlet 6.

[0052] It should be noted that the deodorant liquid can be selected from activated carbon solution, biological enzyme preparation, chemical deodorants (such as phenol-based, ammonia-based compounds, aromatic compounds), etc. These agents can effectively decompose the odor components and improve the gas purification effect. After being treated by the atomizing deodorization device 5, more than 15% of the odor components can be removed, and the odor concentration (dimensionless) can be reduced by more than 90%.

[0053] Further, as Figure 13-14 shown, the high-efficiency absorption device 2, the gas-liquid separation device 3, the high-efficiency adsorption device 4, and the atomizing deodorization device 5 are arranged in a "field" - shaped structure and a skid-mounted steel structure 7 is provided on the outside, making the structure more compact and more convenient for transportation, installation, and disassembly and transfer.

[0054] Among them, the high-efficiency absorption device 2, the gas-liquid separation device 3, the high-efficiency adsorption device 4, and the atomizing deodorization device 5 are arranged in a "field" - shaped structure. In actual implementation, their relative positions can be adjusted while keeping the connection order unchanged. As Figure 2 shown, the high-efficiency absorption device 2 is at the lower right corner. Starting from the lower right corner, the high-efficiency absorption device 2, the gas-liquid separation device 3, the high-efficiency adsorption device 4, and the atomizing deodorization device 5 are arranged in a clockwise direction in sequence, or the high-efficiency absorption device 2, the gas-liquid separation device 3, the high-efficiency adsorption device 4, and the atomizing deodorization device 5 can also be arranged in a counterclockwise direction in sequence (as Fig.13 shown). For the odor treatment device arranged in a counterclockwise direction, its atomizing deodorization device 5 and the total air outlet 6 are arranged in the lower row. In this way, after the odor treatment device is loaded onto the vehicle later, the total air outlet 6 is closer to the connecting air duct 9, so it is convenient for the quick installation of the total air outlet 6 and the connecting air duct 9.

[0055] It should be noted that the high-efficiency absorption device 2, the gas-liquid separation device 3, the high-efficiency adsorption device 4 and the atomization deodorization device 5 all adopt a horizontal structure, and the above four groups of devices are arranged in a "field"-shaped structure to effectively save floor space, and the gas flow inside thereof adopts a U-shaped return design, which will not reduce the flow path of the gas, thereby ensuring the deodorization effect of the gas; In addition, the skid-mounted steel structure 7 mainly includes a plurality of reinforcing beams arranged in transverse, longitudinal and vertical directions, which are spliced ​​or welded together. The skid-mounted steel structure 7 is the supporting frame of the odor treatment device, which is usually made of steel and has the characteristics of high structural strength, corrosion resistance and good weather resistance. Optionally, the reinforcing beam is an I-beam. The setting of the skid-mounted steel structure 7 provides good support and protection for the above-mentioned four groups of devices on the one hand, and on the other hand, it is also convenient for the quick disassembly and installation of the above-mentioned four groups of devices and components such as the dosing device 8, the induced draft fan 10, and the electronic control system 12, and the setting of the skid-mounted steel structure 7 is also convenient for the subsequent installation of the solar panels 13.

[0056] Further, if Fig.14 As shown, a dosing device 8 is provided on the outside of the circulating water tank 204, the main air outlet 6 is connected to the induced draft fan 10 through a connecting air duct 9, an exhaust air duct 11 is provided at one end of the induced draft fan 10, and the dosing device 8 and the induced draft fan 10 are electrically connected to the electronic control system 12 respectively.

[0057] The dosing device 8 is mainly used to add medicine to the inside of the circulating water tank 204. The dosing device 8 mainly includes a medicine storage tank, a dosing pump, a pipeline system and a control system. The medicine storage tank is used to store the medicine to be dosed, and is usually made of anti-corrosion material. The dosing pump controls the dosage and flow rate of the medicine. Common pump types include metering pumps or peristaltic pumps. The pipeline system is used to transport the medicine to the circulating water tank 204 and ensure smooth flow. The control system is electrically connected to the electronic control system 12, and can automatically adjust the amount of medicine according to the amount of medicine inside the circulating water tank 204. The deodorized and purified gas moves from the main air outlet 6 to the connecting air duct 9 driven by the induced draft fan 10, and is finally discharged from the exhaust air duct 11; The circulating water tank 204, the dosing device 8, the induced draft fan 10 system and the electronic control system 12 are an important integrated system that works together to ensure the dosage of the medicine. Through reasonable design and control, the efficiency of the system operation can be effectively improved and the rational use of resources can be guaranteed.

[0058] Further, if Fig.15 As shown, the odor treatment device is arranged on a vehicle, and a solar panel 13 is fixedly provided on the upper end of the skid-mounted steel structure 7, and the solar panel 13 is electrically connected to the electric control system 12, the dosing device 8, and the induced draft fan 10 respectively.

[0059] The odor treatment device is designed to be used on a vehicle and is mobile, which is convenient for coping with the odor treatment needs of multiple places. The design of the skid-mounted steel structure makes the overall device stable and easy to install and disassemble, so it has strong adaptability and is convenient for odor treatment in different environments. The solar panel 13 is installed on the upper end of the skid-mounted steel structure 7 as a renewable energy collection unit to provide power for the entire system and reduce the dependence on external power sources. The solar panel 13 is connected to the electric control system 12 and electric control equipment (such as the dosing device 8 and the induced draft fan 10) through a controller, and can provide the required power for these equipment in real time. The solar panel 13 converts solar energy into electrical energy and supplies power to the electric control system 12 and other equipment. The system uses a power management module to monitor and store electrical energy to ensure that it can still work normally when there is insufficient sunlight; The electronic control system 12 is the "brain" of the entire odor treatment device, responsible for the control and coordination of various components. It mainly has the following functions: real-time monitoring of the output current and stored electrical energy of the solar panels to ensure that the system always has sufficient energy support, automatically adjusting the dosage of the dosing device 8 and the wind speed of the induced draft fan 10 according to the information fed back by the sensors to ensure the treatment effect, and recording and analyzing the system operation data, including power consumption, dosage of the drug and treatment effect, to facilitate subsequent maintenance and improvement.

[0060] Embodiment 2 The components that are the same or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: The present invention also provides a method for treating odor in a landfill, comprising the following steps: Step 1, sending the odor generated by the landfill into the interior of the high-efficiency absorption device 2 along the main air inlet 1; Step 2: The odor enters the absorption packing layer 202, and at the same time, the spray pump 205 pumps the agent from the circulating water tank 204 to the spray pipe 206. The agent is sprayed into the absorption packing layer 202 through the spray pipe 206 and fully contacts the odor. The liquid phase gas passing through the absorption packing layer 202 enters the demisting packing layer 203 and preliminarily intercepts the droplets in the liquid phase gas. Finally, the liquid phase gas is discharged from the absorption outlet area 207.
