DETAILED DESCRIPTION

[0015] This embodiment provides a device for collecting and pre-processing high-humidity and hot gas, such as Figure 1-Figure 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 mutually parallel air delivery pipes 6 are arranged in the ventilation pipe 2. The bottom of the air delivery pipe 6 is connected in parallel with the inner space of the air collecting hood 1, so that the high-humidity and hot gas 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 gas; 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 out of the device so that the gas after water filtering 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.

[0016] Optionally, the gas collecting hood 1 is in the shape of a truncated cone that is small at the top and large at the 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.

[0017] Optionally, the ventilation pipe 2 is a vertical cylinder as a whole, including an outer tube shell and at least two gas pipes inside, the gas pipes are hollow cylinders, the gas pipes are arranged in parallel, the tube shell is wrapped around the outside of the gas pipes to protect the gas pipes, and there is a gap between the inner wall of the tube shell and the outer wall of the gas pipes. The process of the gas collected by the gas hood 1 rising along the gas pipe is also the process of the gas gradually cooling, and the moisture contained in the gas is also condensed, and the formed water droplets flow down along the inner wall of the gas pipe (returning to the outside through the gas hood 1).

[0018] Optionally, the bottom end of the gas pipeline 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 pipeline and then rise along the gas pipeline.

[0019] Optionally, a transition pipe 11 is provided at the upper part 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; A temperature sensor is provided in the transition pipe 11 for real-time monitoring of the original temperature of the collected gas sample.

[0020] Optionally, a three-way valve is provided at the bottom of the gas pipeline, two openings of the three-way valve can be connected to the gas pipeline, and the third opening is connected to the branch pipe 12, which is provided on the side of the gas pipeline 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 pipeline, another gas pipeline is used to transport the gas sample, and the gas pipeline with too many water droplets is connected to the branch pipe, and the water droplets above the three-way valve in the gas pipeline are discharged through the branch pipe; The top end of the gas delivery pipe is detachably connected to the water filter part 3 , so that the gas delivery pipe for conveying the gas sample can be connected to the water filter part 3 .

[0021] Therefore, the two gas pipes are used in one standby mode and the other in another 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, and 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 continues to be transported, it will be detrimental to the dehumidification and cooling of the gas. Therefore, it is necessary to stop dehumidifying. 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 disabled 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 alternate dehumidification.

[0022] Optionally, the collection and pretreatment device is provided with an equipment bin 13 corresponding to the position of the water filter part 3 and the spiral cooling tube 4, which is used to accommodate the water filter part 3, the spiral cooling tube 4 and the cooling fan 8; a control rail is provided on the inner wall of the equipment bin 13, and the spiral cooling tube 4 is slidably connected to the control rail, and 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 rail together with the spiral cooling tube 4 to switch the connected air supply pipe; 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.

[0023] 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 water filtering section 3 is further cooled while rising along the spiral cooling tube 4. The cooling fan 8 blows downward to promote cooling. Water droplets condensed from the gas flow down along the inner wall of the spiral cooling tube 4 to the water filtering section 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.

[0024] Further optionally, the top end of the equipment compartment 13 is detachably connected to the heat dissipation cover 5, and the bottom end 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.

[0025] Further optionally, the control guide rail includes a circle of circular tracks 15 and two vertical tracks 16, the circular tracks 15 are arranged horizontally and around the circumference of the equipment bin 13, the two vertical tracks 16 are respectively arranged at opposite positions of the inner wall of the equipment bin 13, the top of the vertical tracks 16 are connected to the circular tracks 15, and the bottom of the vertical tracks 16 is provided with a limit part to limit the lower limit position of the spiral cooling tube 4 to prevent the water filter part 3 from hitting the top of the gas pipe; An inclined connecting rod 17 is provided on both sides of the spiral cooling tube 4, and 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 circular track 15 through a slider, and 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, so as 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.

[0026] 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 another gas pipe; An outer shell 20 is provided on the outside of the ceramic sieve plate 19. The top of the shell 20 is connected to a connecting pipe 22, and the bottom is provided with a quick-plug interface for quick connection to a gas pipeline.

[0027] 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 in 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 outer 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.

[0028] 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, so as to promote the branch pipe to dry quickly so that it can be put into use again; A water baffle 21 is provided above the cooling fan 2 9 to prevent water droplets condensed by cooling on 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 delivery pipe.

[0029] When in use, the gas pipe for conveying gas samples is connected to the bottom of the shell through a quick-plug interface, so that the gas path of the gas pipe, the water filter part 3 and the spiral cooling tube 4 is unobstructed. The high-humidity and hot gas collected by the gas collecting hood 1 is initially cooled by the gas pipe, and then filtered by the ceramic sieve plate 19 to remove most of the water vapor, and then enters 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, and then flow into the shell through the connecting pipe, and then flow down to the gas pipe through the ceramic sieve plate 19, and the gas after drying and cooling is discharged from the exhaust pipe. The outer wall of the spiral cooling tube 4 will also condense to produce water droplets. Under the purge of the cooling fan 8, this part of the water droplets fall, pass through the water filter part 3 or the side wall of the equipment compartment 13, and finally be discharged from the heat dissipation holes at the bottom of the equipment compartment 13. The water baffle 21 and the shell can protect the gas inside the cooling fan 29 and the ceramic sieve plate 19 from being affected by the falling water in 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.

[0030] 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 .

[0031] 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.

[0032] When there are too many water droplets on the wall of a gas pipeline, it will affect the dehumidification of the gas sample in the gas pipeline, that is, the high-humidity and hot gas may lead the water vapor to move back to the ceramic sieve plate 19, causing the water vapor above the ceramic sieve plate 19 to increase, affecting the dehumidification efficiency of the gas sample. At this time, it is necessary to replace another gas pipeline to transport the gas sample, and the gas pipeline with more water vapor is dried.

[0033] When switching, the three-way valve of the original gas pipeline is connected to its own branch pipe to cut off the gas supply; the slider of the connecting rod 17 of the spiral cooling tube 4 moves upward along the vertical track 16 to the circumferential track 15, at which time the shell equipped with the ceramic sieve plate 19 also moves upward and is disconnected from the originally connected gas pipeline; the two sliders move along the circumferential track 15, thereby driving the spiral cooling tube 4 and the water filter 3 to rotate 180°, so that the shell equipped with the ceramic sieve plate 19 rotates to the top of another gas pipeline, and at the same time, the cooling fan 29 rotates to the top of the original gas pipeline; 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 tube 4 and the water filter 3 to move downward, so that the quick-plug interface at the bottom of the shell is connected to the gas pipeline to be used, and the three-way valve of the gas pipeline is connected to the bottom and the top of the gas pipeline, so that the gas sample can be transported, and the gas path of the ceramic sieve plate 19 and the spiral cooling tube 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 air supply pipe needs to be switched again, the spiral cooling tube 4 can be turned back in the opposite direction to reset the hose.

[0034] When drying, the cooling fan 29 is directly above the original gas pipe and starts to supply air to blow the water droplets in the gas pipe to the bottom of the gas pipe and then discharge them through the branch pipe until the gas pipe is dry and the next use is ready, then the cooling fan 29 is stopped.

[0035] Optionally, the heat dissipation cover 5 is in the shape of a truncated cone with a small top and a large bottom. 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 .

[0036] The air 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.

[0037] Further optionally, a cooling fan 3 10 is provided on the inner wall of the equipment bin 13, the cooling fan 3 10 is lower than the circular track 15, and the air outlet faces the spiral cooling pipe 4, so as to blow the spiral cooling pipe 4 and assist in cooling.

[0038] Since the cooling fan three 10 is located at the side of the spiral cooling tube 4, it is not affected by the water drops outside 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.

[0039] 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 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, and a gap is left between the edge of the waterproof cover and the inner wall of the equipment compartment to allow 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.

[0040] 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; 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.

[0041] The water droplets falling from the spiral cooling tube 4 will be discharged from the heat dissipation holes at the bottom of the equipment compartment 13, and the rest will fall into the ventilation pipe 2. The bottom of the ventilation pipe 2 is sealed with a gas collecting hood 1, and the water will accumulate in the ventilation pipe 2, so that the bottom of the gas pipe (where the gas sample temperature is relatively high) is immersed in the condensed water of the ventilation pipe 2 for heat exchange, thereby cooling the gas in the gas pipe. The water will preferentially gather at the bottom and lower part of the ventilation pipe 2, and the corresponding gas temperature at the bottom and lower part of the gas pipe is also relatively high, which can achieve good heat exchange. The water in the ventilation pipe 2 can accumulate to the upper part of the ventilation pipe 2. According to the gas temperature at the sampling point, the position of the drain port of the ventilation pipe 2 is reasonably set to discharge the accumulated water in the ventilation pipe 2 and promote water renewal. The drain port can be located at the lower, middle or upper part of the ventilation pipe 2.
