[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0038] Please refer to the attached Figures 1 to 4 An embodiment of the present application provides an in-well atomization device 100, which is applied to an underground environment. The in-well atomization device 100 includes an outer tube 10, a manhole cover 20, an atomization assembly 30 and an exhaust pipe 40. The manhole cover 20 is located on the upper side of the outer tube 10, the atomization assembly 30 is located on the lower side of the manhole cover 20, and the exhaust pipe 40 is arranged on the outer side of the outer tube 10.

[0039] In the embodiment of the present application, the outer tube 10 serves as a supporting component of the atomization device 100 in the well. The outer tube 10 is used to support the manhole cover 20, the atomization assembly 30 and the exhaust pipe 40. The outer tube 10 is penetrated through the ground and is located in the well. The outer tube 10 is connected to the groundwater flow channel in the underground environment and stores the groundwater transported through the groundwater flow channel, so that the groundwater transported by the groundwater flow channel can flow into the outer tube 10.

[0040] In the embodiment of the present application, the manhole cover 20 is located on the upper side of the outer tube 10. The manhole cover 20 is sealingly mounted on the outer tube 10 and blocks the top opening of the outer tube 10, thereby preventing the groundwater in the outer tube 10 from flowing to the external environment through the top opening and preventing the un-atomized groundwater from flowing directly to the external environment.

[0041] In the embodiment of the present application, the atomization assembly 30 is located in the outer tube 10, and the atomization assembly 30 includes an inner tube 31 and an atomization head 32; the inner tube 31 is located in the outer tube 10 and is arranged in a vertical direction; the lower end of the inner tube 31 is close to the bottom of the outer tube 10, and adsorbs groundwater under the action of negative pressure; the atomization head 32 is installed at the upper end of the inner tube 31, so that the groundwater in the outer tube 10 flows to the atomization head 32 through the inner tube 31, and the atomization head 32 atomizes the groundwater transported through the inner tube 31, and outputs volatile organic gases in a downwardly inclined manner, so that the volatile organic gases are discharged to the outside of the atomization head 32.

[0042] In the embodiment of the present application, the exhaust pipe 40 passes through the manhole cover 20, and the air inlet end of the exhaust pipe 40 is located below the atomizing head 32 and close to the output end of the atomizing head 32; the air inlet end of the exhaust pipe 40 adsorbs volatile organic gases under the action of negative pressure; the exhaust end of the exhaust pipe 40 is located on the outer surface of the manhole cover 20, and discharges volatile organic gases to the outside, so as to facilitate the discharge of volatile organic gases to the outside through the exhaust pipe 40. When the volatile organic gases dissolved in the groundwater change from high pressure to low pressure in the spray state, the solubility of the volatile organic gases decreases and are precipitated, and are collected by the exhaust pipe 40 to the surface gas collection device, thereby reducing the operation and maintenance costs of subsequent water treatment units and reducing interference with the surrounding environment, effectively improving the remediation efficiency of groundwater containing volatile organic gases while reducing the remediation cost. Optionally, the exhaust pipe 40 is arranged in an L shape.

[0043] The atomizing head 32 includes an atomizing body 321 and a plurality of atomizing output ends 322. The plurality of atomizing output ends 322 are all connected to the atomizing body 321 and are distributed around the atomizing body 321. The plurality of atomizing output ends 322 extend downward and face different directions. The atomizing body 321 is connected to the inner tube 31 so that the groundwater in the outer tube 10 flows to the atomizing body 321 through the inner tube 31. The atomizing body 321 is used to atomize the groundwater transported through the inner tube 31 and output volatile organic gases to the plurality of atomizing output ends 322 so that the volatile organic gases are discharged to the exhaust pipe 40 through the plurality of atomizing output ends 322. The discharge effect of the volatile organic gases relative to the atomizing head 32 is increased by arranging the plurality of atomizing output ends 322.

[0044] The multiple atomization output ends 322 are all arranged in a tubular shape and are arranged in a ring along the peripheral side wall of the atomization body 321, so that the multiple atomization output ends 322 are close to the exhaust pipe 40, so that the volatile organic gas can be discharged outward through the exhaust pipe 40. When the volatile organic gas dissolved in the groundwater changes from a high pressure to a low pressure in the spray state, the solubility of the volatile organic gas decreases and is precipitated, and is collected by the exhaust pipe 40 to the surface gas collection device, thereby reducing the operation and maintenance costs of the subsequent water treatment unit and reducing the interference with the surrounding environment, effectively improving the remediation efficiency of groundwater containing volatile organic gases while reducing the remediation cost.

[0045] The atomizing assembly 30 also includes a pump body 33, which is located in the outer tube 10 and connected to the inner tube 31. The inner tube 31 absorbs groundwater under the negative pressure of the pump body 33, so that the inner tube 31 absorbs the groundwater in the outer tube 10 through the pump body 33 and flows to the atomizing head 32, thereby facilitating the transfer of groundwater in the outer tube 10 to the atomizing head 32.

[0046] The in-well atomization device 100 also includes a stainless steel mesh 50, which is sleeved on the inner wall of the outer tube 10. The stainless steel mesh 50 is located below the atomization head 32 and can guide the water droplets condensed by the atomized groundwater to the inner wall of the inner tube 31, so that the atomized groundwater can be gathered on the inner wall of the inner tube 31 through the stainless steel mesh 50, thereby facilitating the atomized groundwater to flow into the inner tube 31 for circulation. Optionally, the stainless steel mesh 50 is arranged in a conical shape.

[0047] A through hole 50a is provided at the bottom of the stainless steel mesh 50, and the inner tube 31 is penetrated by the through hole 50a. The outer wall of the inner tube 31 and the inner wall of the through hole 50a are close to each other. The outer wall of the inner tube 31 receives the water droplets gathered by the stainless steel mesh 50, so that the water droplets flow to the inner tube 31 under the guiding force of the stainless steel mesh 50, thereby ensuring the flow direction of the water droplets relative to the inner tube 31.

[0048] The outer wall of the inner tube 31 receives the water droplets gathered by the stainless steel mesh 50. The water droplets flow downward along the outer wall of the inner tube 31 and can flow back to the lower end of the inner tube 31, so that the water droplets can circulate through the inner tube 31, thereby ensuring the atomization effect of the atomizing head 32 on the groundwater in the inner tube 31.

[0049] The manhole cover 20 is provided with a connecting hole 20a, and the atomization device 100 in the well is provided with a detection component 60, which is connected to the connecting hole 20a so that the detection component 60 can be connected relative to the manhole cover 20 through the connecting hole 20a. The detection end of the detection component 60 is located in the outer tube 10 and is used to detect volatile organic gases output through the atomization head 32, so that the detection component 60 can display the vacuum degree in the groundwater flow channel in the underground environment in real time.

[0050] The well atomization device 100 further includes a sieve tube 70, which is arranged on the inner side of the outer tube and sleeved on the inner tube. The sieve tube 70 is used to filter impurities in the groundwater in the outer tube.
