[0002] The temperature inside the Earth's crust is higher than the surface, and the gases inside the crust have a higher temperature. When geological movements undergo drastic changes, the composition of the gases inside the crust will also change. The most representative are the gases that escape or emit directly from the ground, which are of great research value.

DETAILED DESCRIPTION

[0025] This embodiment provides a device for collecting and pre-processing high-humidity and hot gas, such as Figures 1-4 As shown, from bottom to top, it includes an air collecting hood 1, a ventilation pipe 2, a water filter 3, a spiral cooling pipe 4, and a heat dissipation hood 5, which are connected in sequence. At least two parallel air delivery pipes 6 are provided in the ventilation pipe 2. The bottom of the air delivery pipe 6 is connected in parallel to the internal space of the air collecting hood 1, so that the high-humidity and hot air entering the air collecting hood 1 rises along the air delivery pipe. The top of the air delivery pipe is detachably connected to the water filter 3 to filter and remove most of the moisture in the high-humidity and hot air.

[0026] The water filtering part 3 is connected to the air inlet of the spiral cooling tube 4, and the air outlet of the spiral cooling tube 4 is connected to the exhaust pipe 7. The exhaust pipe 7 extends to the outside of the device, so that the gas after water filtration passes through the spiral cooling tube 4, continues to condense and remove water, and finally is discharged from the device; a cooling fan 8 is provided above the spiral cooling tube 4 for outputting cold energy for the spiral cooling tube 4, and a heat dissipation cover 5 is above the cooling fan 8 for quickly dissipating heat for the cooling fan 8.

[0027] Optionally, the gas collecting hood 1 is in the shape of a cone with a small top and a large bottom, and the middle and lower parts of the gas collecting hood 1 have a hollow chamber for collecting gas samples; the upper part of the gas collecting hood 1 is solid and connected to the outer wall of the ventilation pipe 2, so that the gas collecting hood 1 and the ventilation pipe 2 are connected as one.

[0028] Optionally, the ventilation tube 2 is an overall vertical cylindrical structure, comprising an outer tube shell and at least two inner gas pipes. The gas pipes are hollow cylindrical and arranged in parallel. The tube shell wraps around the outside of the gas pipes to protect them, with a gap between the inner wall of the tube shell and the outer wall of the gas pipes. As the gas collected by the gas collection hood 1 rises along the gas pipes, it gradually cools, and the moisture contained in the gas condenses, forming water droplets that flow down the inner wall of the gas pipes (returning to the outside through the gas collection hood 1).

[0029] Optionally, the bottom end of the gas pipe is connected to the hollow chamber of the gas collecting hood 1, so that the high-humidity and hot gas collected by the gas collecting hood 1 can be input into the gas pipe and then rise along the gas pipe.

[0030] Optionally, a transition pipe 11 is provided on the upper portion of the gas collecting hood 1. The inner diameter of the transition pipe 11 is larger than the sum of the inner diameters of the gas transmission pipes. The bottom end of the transition pipe 11 is connected to the hollow chamber of the gas collecting hood 1, and the top end is connected in parallel to the bottom ends of all the gas transmission pipes.

[0031] A temperature sensor is provided in the transition pipe 11 for real-time monitoring of the original temperature of the collected gas sample.

[0032] Optionally, a three-way valve is provided at the bottom of the gas pipe, two openings of the three-way valve can be connected to the gas pipe, and the third opening is connected to the branch pipe 12, which is provided on the side of the gas pipe and passes through the tube shell of the ventilation pipe 2 to connect to the external space of the ventilation pipe 2; when there are too many water droplets in one gas pipe, the other gas pipe is used to transport the gas sample, and the gas pipe with too many water droplets is connected to the branch pipe, and the water droplets above the three-way valve in the gas pipe are discharged through the branch pipe;

[0033] The top end of the gas delivery pipe is detachably connected to the water filter 3 , so that the gas delivery pipe for delivering the gas sample can be connected to the water filter 3 .

[0034] Thus, the two gas pipes are used in a standby mode while the other is used in a backup mode. After the temperature of the gas sample is measured in the transition pipe 11, it enters the gas pipe connected to the three-way valve. The gas rises along the gas pipe until it reaches the water filter 3. Due to the long-term transportation of high-humidity and hot gas in the other gas pipe, there is too much water vapor inside the gas pipe. If the gas is continued to be transported, it will be detrimental to the dehumidification and cooling of the gas. Therefore, it is necessary to stop dehumidification. The three-way valve connects the upper part of the gas pipe with its own branch pipe and cuts off the bottom of the gas pipe, so that the new gas in the gas collecting hood 1 cannot enter the closed gas pipe, but enters the gas pipe opened next to it. The water droplets in the deactivated gas pipe flow down along its own inner wall and are then discharged through the branch pipe. The two gas pipes of the present invention are used alternately for dehumidification.

[0035] Optionally, the collection and pretreatment device is provided with an equipment compartment 13 corresponding to the position of the water filter part 3 and the spiral cooling tube 4, for accommodating the water filter part 3, the spiral cooling tube 4 and the cooling fan 8; a control guide rail is provided on the inner wall of the equipment compartment 13, and the spiral cooling tube 4 is slidably connected to the control guide rail. The water filter part 3 is connected to the air inlet at the bottom of the spiral cooling tube 4 through a connecting tube 22, so that the water filter part 3 can move along the control guide rail together with the spiral cooling tube 4 to switch the connected air supply pipe;

[0036] The exhaust pipe 7 is provided on the top of the equipment compartment 13, and the air outlet on the top of the spiral cooling pipe 4 is connected to the exhaust pipe through a hose to prevent the movement of the spiral cooling pipe 4 from affecting the connection between the spiral cooling pipe 4 and the exhaust pipe, thereby ensuring smooth exhaust at any time.

[0037] Further optionally, the spiral cooling tube 4 is formed by spirally winding a circle of pipes, maintaining equal intervals in the vertical direction, and winding in a circle in the horizontal direction. The gas passing through the filtered water part 3 is further cooled while rising along the spiral cooling tube 4. The cooling fan 8 blows downward to promote cooling. The water droplets condensed from the gas flow down along the inner wall of the spiral cooling tube 4 to the filtered water part 3. The dehumidified and cooled gas is discharged from the exhaust pipe. The exhaust pipe is connected to an external gas collecting device for collecting gas samples after cooling and dehumidification to facilitate subsequent detection of gas components.

[0038] Further optionally, the top of the equipment compartment 13 is detachably connected to the heat dissipation cover 5, and the bottom of the equipment compartment 13 is detachably connected to the top of the ventilation pipe 2. The top and bottom of the equipment compartment 13 are respectively provided with a plurality of heat dissipation holes 14 for dissipating heat for the cooling fan 8 and facilitating air flow in the equipment compartment 13.

[0039] Further optionally, the control guide rail includes a circle of circular tracks 15 and two vertical tracks 16, the circular track 15 is horizontally arranged and arranged along the circumference of the equipment compartment 13, and the two vertical tracks 16 are respectively arranged at opposite positions on the inner wall of the equipment compartment 13, the top of the vertical track 16 is connected to the circular track 15, and the bottom end of the vertical track 16 is provided with a limit portion to limit the lower limit position of the spiral cooling tube 4 to prevent the water filter part 3 from colliding with the top of the gas pipe;

[0040] An inclined connecting rod 17 is provided on each side of the spiral cooling tube 4. The connecting rod 17 corresponds to the vertical track 16 one by one. The top of the connecting rod 17 is connected to the vertical track 16 and the circumferential track 15 through a slider. The bottom of the connecting rod 17 is fixedly connected to the spiral cooling tube 4. The height of the top of the connecting rod 17 is greater than the height of the bottom to prevent water droplets condensed on the outer surface of the spiral cooling tube 4 from flowing into the control guide rail along the connecting rod 17.

[0041] Optionally, the water filter 3 includes a base 18, a cooling fan 9 and a ceramic sieve plate 19. The base 18 is annular, and the cooling fan 9 and the ceramic sieve plate 19 are respectively arranged at relative positions on both sides of the base 18, so that the cooling fan 9 can face the top of one gas pipe and the ceramic sieve plate 19 can face the top of the other gas pipe.

[0042] An outer shell 20 is provided on the outside of the ceramic sieve plate 19. The top of the shell 20 is connected to the connecting pipe 22, and the bottom is provided with a quick-plug interface for quick connection to the gas pipe.

[0043] Further optionally, the ceramic sieve plate 19 is in the shape of a circular plate and is evenly and densely covered with through holes. The ceramic sieve plate 19 is located on the cross section of the gas channel and is used to filter most of the moisture and impurities in the gas. The intercepted water droplets can return to the gas pipe along the inner wall of the shell and then flow down along the gas pipe. The filtered gas is input into the bottom of the spiral cooling tube 4 through the connecting pipe 22.

[0044] Further optionally, the air outlet of the cooling fan 2 9 is downward and directly facing the deactivated air pipe, and the cooling fan 2 9 blows into the air pipe to promote the water droplets inside the air pipe to flow downward quickly and be discharged through the branch pipe, thereby promoting the branch pipe to dry quickly so that it can be put into use again;

[0045] A water baffle 21 is provided above the cooling fan 2 9 to prevent water droplets condensed from the outer side of the spiral cooling pipe 4 from falling onto the cooling fan 2 9 or into the inside of the deactivated air supply pipe.

[0046] During use, the gas pipe for transporting gas samples is connected to the bottom of the housing via a quick-connect connector, ensuring unobstructed airflow between the pipe, the water filter 3, and the spiral cooling tube 4. The hot and humid gas collected by the gas hood 1 is initially cooled in the pipe, then filtered through the ceramic sieve plate 19 to remove most of the water vapor before entering the spiral cooling tube 4. Under the purge of the cooling fan 8, the gas in the spiral cooling tube 4 is further cooled, and the resulting water droplets flow down along the inner wall of the spiral cooling tube 4, then flow into the housing through the connecting pipe, and then flow down through the ceramic sieve plate 19 into the pipe. The dried and cooled gas is then discharged through the exhaust pipe. The outer wall of the spiral cooling tube 4 also condenses to produce water droplets. Under the purge of the cooling fan 8, these water droplets fall, pass through the water filter 3 or the side wall of the equipment compartment 13, and are finally discharged through the heat dissipation holes at the bottom of the equipment compartment 13. The water baffle 21 and the housing protect the gas inside the cooling fan 9 and the ceramic sieve plate 19 from being affected by water falling into the equipment compartment 13. The heat dissipation holes at the top and bottom of the equipment compartment 13 can also provide air intake and air outlet for the two cooling fans, so that the fans can operate normally and dissipate heat for the fans at the same time.

[0047] The water baffle 21 is close to the cooling fan 2 9 and also serves as a heat sink for the cooling fan 2 9. Water droplets falling on the water baffle 21 can also cool the water baffle 21, which is beneficial to the cooling of the water baffle 21 and the heat dissipation of the cooling fan 2 9.

[0048] The inner diameter of the equipment compartment 13 is larger than the inner diameter of the ventilation pipe 2 , so that in addition to the portion of the bottom of the equipment compartment 13 connected to the ventilation pipe 2 , there is also a portion of the area for heat dissipation holes.

[0049] When too many water droplets cling to the wall of a gas pipe, it can affect the dehumidification of the gas sample within the pipe. This means that the hot and humid gas may carry the water vapor back to the ceramic sieve plate 19, causing more water vapor above the ceramic sieve plate 19 and affecting the dehumidification efficiency of the gas sample. In this case, it is necessary to replace the gas pipe with another one to transport the gas sample, while the one with more water vapor is dried.

[0050] When switching, the three-way valve of the original gas supply pipe is connected to its own branch pipe, cutting off the gas supply; the slider of the connecting rod 17 of the spiral cooling pipe 4 moves upward along the vertical track 16 to the circumferential track 15. At this time, the shell with the ceramic sieve plate 19 also moves upward and is disconnected from the originally connected gas supply pipe; the two sliders move along the circumferential track 15, thereby driving the spiral cooling pipe 4 and the water filter part 3 to rotate 180°, so that the shell with the ceramic sieve plate 19 rotates to the top of the other gas supply pipe, and at the same time, the cooling fan 2 9 rotates to the top of the original gas supply pipe; at this time, the two sliders correspond to the vertical track 16 respectively, and the two sliders move downward along the vertical track 16, thereby driving the spiral cooling pipe 4 and the water filter part 3 to move downward, so that the quick-plug interface at the bottom of the shell is connected to the gas supply pipe to be used. At this time, the three-way valve of the gas pipe connects the bottom and the top of the gas pipe, so that the gas sample can be transported, and the gas path of the ceramic sieve plate 19 and the spiral cooling pipe 4 is also connected. Since the air outlet of the spiral cooling tube 4 is connected to the exhaust pipe through a hose of a certain length, the spiral cooling tube 4 rotates and pulls the hose, but does not affect the connection with the exhaust pipe. When the gas pipe needs to be switched again, the spiral cooling tube 4 can be rotated in the opposite direction to reset the hose.

[0051] During drying, the cooling fan 2 9 is directly above the original gas supply pipe and starts to supply air to blow the water droplets in the gas pipe to the bottom of the gas pipe, and then discharged from the branch pipe until the gas pipe is dry and ready for next use, and then the cooling fan 2 9 is stopped.

[0052] Optionally, the heat dissipation cover 5 is in the shape of a truncated cone with a smaller upper portion and a larger lower portion. The inner diameter of the heat dissipation cover 5 is larger than the inner diameter of the equipment compartment 13 . The larger heat dissipation compartment area is beneficial to the heat dissipation of the cooling fan in the equipment compartment 13 .

[0053] The gas collecting hood 1, the ventilation pipe 2, the equipment compartment 13, the spiral cooling pipe 4, the base 18, and the heat dissipation hood 5 are all concentrically arranged.

[0054] Further optionally, a cooling fan 3 10 is provided on the inner wall of the equipment compartment 13, the cooling fan 3 10 is lower than the circular track 15, and the air outlet is facing the spiral cooling pipe 4, which blows the spiral cooling pipe 4 to assist in cooling.

[0055] Since the cooling fan three 10 is located on the side of the spiral cooling tube 4, it is not affected by water drops falling from the spiral cooling tube 4. The cooling fan three 10 can use the heat dissipation holes above and below the equipment compartment 13 to dissipate heat.

[0056] Further optionally, a cooling fan four 23 is provided between the spiral cooling pipe 4 and the water filter part, and the air outlet of the cooling fan four is upward, blowing air directly towards the spiral cooling pipe 4 to assist in cooling; preferably, a waterproof cover is provided above the cooling fan four, and the waterproof cover 24 can cover the space above the cooling fan four and the water filter part to prevent water droplets falling from the outer side of the spiral cooling pipe from falling on the fan blades or motor of the cooling fan four and the water filter part. A gap is left between the edge of the waterproof cover and the inner wall of the equipment compartment, allowing water droplets to fall and the air supply of the cooling fan four to flow upward. At this time, the water filter part is not provided with a water baffle 21, and the connecting pipe 22 passes through the waterproof cover and is then connected to the spiral cooling pipe.

[0057] Further optionally, a temperature sensor is provided in the equipment compartment 13 for real-time monitoring of the temperature in the equipment compartment, and indirectly guiding the power or speed of the cooling fan 1 and the cooling fan 3;

[0058] The lines of the temperature sensor, cooling fan 1 and cooling fan 3 pass through the side wall of the equipment compartment and are connected to an external power supply.

[0059] In addition to being discharged from the heat dissipation holes at the bottom of the equipment compartment 13, the water droplets falling from the spiral cooling tube 4 will fall into the vent pipe 2. The bottom of the vent pipe 2 is sealed with a gas collecting hood 1, and water will accumulate in the vent pipe 2, so that the bottom of the gas pipe (where the gas sample temperature is higher) is immersed in the condensed water of the vent pipe 2, and heat exchange is performed to cool the gas in the gas pipe. The water will preferentially gather at the bottom and lower part of the vent pipe 2, and the corresponding gas temperature at the bottom and lower part of the gas pipe is also higher, which can achieve good heat exchange. The water in the vent pipe 2 can accumulate to the upper part of the vent pipe 2. According to the gas temperature at the sample collection point, the position of the drain outlet of the vent pipe 2 is reasonably set to discharge the water accumulated in the vent pipe 2 and promote water renewal. The drain outlet can be located at the lower, middle or upper part of the vent pipe 2.
