It is through the construction of extraction wells in situ in the contaminated site, through the extraction pipeline and pump system, the organic volatile gas pollutants, contaminated groundwater and non-aqueous liquid in the contaminated site are extracted to the ground treatment system for treatment, thereby achieving in-situ soil and groundwater pollution elimination. Before implementing the remediation, a detailed assessment of the contaminated site is required, including the scope of pollution, type and concentration of pollutants, stratum structure, etc., in order to determine the design and operation parameters of the extraction system;

[0003] After searching, a Chinese patent discloses an in-situ multiphase extraction well device for a contaminated site, and its application publication number is CN109967509B. The patent has an above-ground main pipe, an extraction wellhead, an extraction screen, a liquid phase extraction pipe, a gas phase extraction pipe and an injection pipe. The extraction wellhead and the extraction screen are sealed and connected. One end of the liquid phase extraction pipe passes through the extraction wellhead and is placed in the extraction screen, and the other end is connected to the above-ground main pipe. One end of the gas phase extraction pipe is connected to the gas outlet of the extraction wellhead, and the other end is connected to the above-ground main pipe. The above-ground main pipe is connected to a vacuum device. The invention can simultaneously realize a dual-channel extraction path for gas and liquid phases. The double-port improvement on the extraction wellhead not only improves the extraction efficiency, but also greatly saves the cost of well construction.

[0004] When treating sewage, integrated multiphase extraction equipment for in-situ remediation of contaminated sites is needed. The problems with the prior art are: since the liquid phase and the gas phase need to be extracted at the same time, when the equipment is buried for use, not only the extraction pipe body needs to be installed, but also the separation equipment needs to be erected, and the installation process is relatively cumbersome. After the extraction pipe is installed in the preset hole, the filter material needs to be filled between the well pipe and the borehole wall. The efficiency of disassembly of the equipment pipeline and the extraction pipe body after treatment needs to be improved, which makes it inconvenient to use and also fails to promptly and effectively treat the generated waste gas.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By arranging an outer extraction tube to cooperate with the inner extraction tube, a hollow frame is provided to insert into the inner side of the outer extraction tube. The filter filler can be quickly replaced and removed by replacing or vertically disassembling the hollow frame. After the outer extraction tube is installed in the preset hole, the hollow section at the bottom is used to support the internal hollow frame structure and ensure that liquid and gaseous pollutants can pass through the hollow frame and enter the inner side of the inner extraction tube through the through hole after preliminary filtration of the filter filler and be extracted upward. The interception net installed on the outside of the hollow section can prevent solid matter from entering the inner side of the structure and causing blockage. The quick-release assembly connected to the outer extraction tube through the connecting plate is attached to the inner side of the connecting plate through the auxiliary shell to clamp the contact between the structures. The negative pressure water vapor extraction pump extracts water from the inner extraction tube through the auxiliary shell. The inner side of the quick-release assembly is extracted to form a negative pressure to extract multi-phase impurities into the sub-shell of the quick-release assembly and directly discharge them into the waste liquid tray connected thereto. The gaseous impurities with lower density will be transported to the waste gas treatment box for further treatment through the first connecting pipe connected to the flange on the top of the sub-shell, and the liquid impurities will be sent to the waste liquid treatment pump along the discharge pipe for subsequent treatment. When disassembling the structure, the quick-release assembly can be directly removed from the inner side of the connecting disk and moved away first. Then the equipment frame can be connected to the lifting equipment, and then the clamp claw can be clamped on the outside of the external extraction pipe to complete the connection of the structure. Then the equipment frame can be clamped on the outside of the straight section of the clamp claw. The entire external extraction pipe can be removed by lifting the lifting equipment, and the entire structure needs to be placed horizontally. When a piece of equipment is installed for cleaning and maintenance or replacement of parts, the combination frame can also be connected to the equipment frame through the connecting pin, and the contact frame can be pressed against the outside of the external extraction tube to provide support. Then, the equipment frame and the combination frame can be placed flat on the ground on the side away from the external extraction tube to complete the horizontal placement of the structure, which is convenient for maintenance of the structure. Then the user selects the corresponding concentrated medicine according to the composition of the exhaust gas, and the user adds the concentrated medicine into the liquid storage bin, and then adds the diluted medicine into the reaction bin. The exhaust gas enters the exhaust pipe through the first connecting pipe, and the fan provides more power for the exhaust gas. The wavy exhaust pipes distributed at intervals in the upper and lower layers can more evenly disperse the exhaust gas in the medicine liquid discharged into the reaction bin, thereby improving the waste gas. The contact time between the gas and the liquid medicine is increased, and at the same time, the output end of the motor drives the stirring rod to rotate, and the bubbles of the liquid medicine and the exhaust gas are stirred to break them up, thereby further improving the reaction time of the liquid medicine and the exhaust gas. The liquid medicine at the bottom of the reaction chamber enters the interior of the filter chamber through the square tube, and the concentration of the liquid medicine can be detected by the concentration detection sensor, so as to control the second water pump and the fourth connecting pipe to automatically replenish its concentration, thereby ensuring the reaction effect of the liquid medicine. The filter net inside the filter chamber can filter the reacted liquid medicine, and the baffle after cleaning can make the filtered reactant slide toward the sewage outlet, and the user can discharge the reactant from the filter chamber through the sewage outlet. The filtered liquid medicine enters the interior of the annular tube through the first water pump and the third connecting pipe, and is finally atomized through the nozzle.When the exhaust gas moves upward through the gas collecting hopper, the atomized liquid medicine reacts with the exhaust gas again, further improving the reaction effect of the exhaust gas and the liquid medicine, thereby improving the exhaust gas treatment effect. The reacted exhaust gas is discharged upward through the exhaust port. At this time, the exhaust gas can be dried by the desiccant on its top. The dried exhaust gas enters the interior of the gas distributor through the second connecting pipe, and then the exhaust gas moves upward through the adsorption tube. The exhaust gas can be adsorbed by the activated carbon rod and treated again. The treated exhaust gas is discharged through the exhaust hole on the top of the exhaust gas treatment box. When the desiccant is drying, the dryness of the desiccant can be detected by the humidity monitoring sensor. When the dryness of the desiccant is lower than the setting, the electric slider drives the slide bar. The surface slides, driving the desiccant to move to one side. At this time, one end of the heating rod is inserted into the interior of the desiccant, and the other end of the desiccant can be at the top of the exhaust port, thereby ensuring uninterrupted drying. At the same time, the heating rod works, and the desiccant can be dried by the heating rod. When the humidity monitoring sensor detects that the desiccant is at a suitable dryness again, the heating rod is turned off and waits for the next drying work. This device has a significant effect on waste gas treatment, can purify harmful waste gas, and greatly reduce the pollution caused by waste gas, so as to meet the emission requirements. At the same time, this device can automatically detect and add medicine and detect drying work, so that the user does not need to control too much, reducing the user's operating difficulty and work intensity.

[0046] Working principle: by setting the outer extraction tube 1 to cooperate with the inner extraction tube 2, a space is provided for the hollow frame 3 to be inserted into the inner side of the outer extraction tube 1. By replacing or vertically disassembling and removing the hollow frame 3, the filter filler 6 can be quickly replaced and removed. After the outer extraction tube 1 is installed in the preset hole, the hollow section at the bottom is used to support the internal hollow frame 3 structure and ensure that liquid and gaseous pollutants can pass through the hollow frame 3, and enter the interior of the inner extraction tube 2 through the through hole after preliminary filtration of the filter filler 6 and be extracted upward. The interception net 7 installed on the outside of the hollow section can prevent solid matter from entering the inside of the structure and causing blockage. The quick-release assembly 9 connected to the outer extraction tube 2 through the connecting plate 8 is fitted to the inner side of the connecting plate 8 through the auxiliary shell 901 to align the structure. The contact between the structures is clamped, and the negative pressure water vapor extraction pump 902 forms a negative pressure by extracting from the inner side of the inner extraction tube 2 to extract the multi-phase impurities into the sub-shell 901 of the quick-install component 9, and directly discharge them into the waste liquid tray 903 connected thereto, and the gaseous impurities with a smaller density will be transported to the waste gas treatment box 25 for further treatment through the first connecting pipe 29 connected to the flange on the top of the sub-shell 901, and the liquid impurities will be sent to the waste liquid treatment pump along the discharge pipe 905 for subsequent treatment. When disassembling the structure, the quick-install component 9 can be directly disassembled from the inner side of the connecting disk 8 and moved away first, and then the equipment frame 11 can be connected to the lifting equipment, and then the clamp 10 can be clamped on the outside of the outer extraction tube 1 to complete The device frame 11 is then clamped on the outside of the straight section of the clamp claw 10, and the entire external extraction tube 1 can be removed by lifting the lifting equipment. When the entire equipment needs to be placed horizontally for cleaning, maintenance or replacement of parts, the combination frame 13 can be connected to the device frame 11 through the connecting pin 12, and the contact frame 14 is pressed against the outside of the external extraction tube 1 to provide support. Then, the device frame 11 and the combination frame 13 can be placed flat on the ground away from the side of the external extraction tube 1 to complete the horizontal placement of the structure, which is convenient for maintenance of the structure. Then, the user selects the corresponding concentrated agent according to the composition of the exhaust gas, and the user adds the concentrated agent into the liquid storage bin 43, and then adds the diluted agent into the reaction bin 2. 6, the exhaust gas enters the exhaust pipe 28 through the first connecting pipe 29, and the exhaust gas is provided with more power by the fan 61. The exhaust gas discharged into the liquid medicine inside the reaction chamber 26 can be more evenly dispersed through the wavy exhaust pipe 28 spaced apart in the upper and lower layers, thereby increasing the contact time between the exhaust gas and the liquid medicine. At the same time, the output end of the motor 33 drives the stirring rod 34 to rotate, and the bubbles of the liquid medicine and the exhaust gas can be dispersed by stirring them, thereby further increasing the reaction time of the liquid medicine and the exhaust gas. The liquid medicine at the bottom of the reaction chamber 26 enters the interior of the filter chamber 42 through the square tube 44, and the concentration of the liquid medicine can be detected by the concentration detection sensor 47, thereby controlling the second water pump 54 and the fourth connecting pipe 53 to automatically replenish its concentration, thereby ensuring the reaction effect of the liquid medicine.The filter screen 46 inside the filter chamber 42 can filter the reacted liquid medicine. The cleaned baffle 45 can make the filtered reactant slide toward the drain port 48. The user can discharge the reactant from the filter chamber 42 through the drain port 48. The filtered liquid medicine enters the interior of the annular tube 49 through the first water pump 52 and the third connecting pipe 51, and is finally atomized through the nozzle 50.

The reacted waste gas is discharged upward through the exhaust port 32. At this time, the waste gas can be dried by the desiccant 57 at its top. The dried waste gas enters the interior of the gas separation seat 35 through the second connecting pipe 36, and then the waste gas moves upward through the adsorption tube 37. The waste gas can be adsorbed by the activated carbon rod 39 and treated again. The treated waste gas is discharged through the exhaust hole 60 at the top of the waste gas treatment box 25. After the user opens the top cover 40 , the activated carbon rod 39 can be replaced. When the desiccant 57 is drying, the humidity monitoring sensor 58 can detect the dryness of the desiccant 57. When the dryness of the desiccant 57 is lower than the setting, the electric slider 56 drives the surface of the slide bar 55 to slide, driving the desiccant 57 to move to one side. At this time, one end of the heating rod 59 is inserted into the interior of the desiccant 57, and the other end of the desiccant 57 can be at the top of the exhaust port 32, thereby ensuring uninterrupted drying. At the same time, the heating rod 59 works, and the desiccant 57 can be dried by the heating rod 59. When the humidity monitoring sensor 58 detects that the desiccant 57 is at a suitable dryness again, the heating rod 59 is turned off and waits for the next drying work. The device has a significant effect on waste gas treatment, can purify harmful waste gas, and greatly reduce the pollution caused by waste gas, so as to meet the emission requirements. At the same time, the device can automatically detect the dosing work and the drying work, so that the user does not need to control too much, reducing the user's operation difficulty and work intensity. ,
