[0030] Four groups of air chambers 12 are provided in the collecting pipe 3, and the four groups of air chambers 12 are equally divided in a ring. The lengths of the first collecting pipe 5, the second collecting pipe 6, the third collecting pipe 7 and the fourth collecting pipe 8 increase successively, and the first collecting pipe 5, the second collecting pipe 6, the third collecting pipe 7 and the fourth collecting pipe 8 are all connected to the air chamber 12 through the pipeline 9, and a sensor 37 is provided in the air chamber 12.

[0031] In this embodiment, the collecting pipe 3 is divided into four groups of air chambers 12, and the four groups of air chambers 12 are opened in a ring-shaped equal division, and the four groups of air chambers 12 are correspondingly connected to the first collecting pipe 5, the second collecting pipe 6, the third collecting pipe 7 and the fourth collecting pipe 8.

[0034] In this embodiment, a column 28 is provided at the bottom of the collecting pipe 3, a motor 18 is provided on the outer wall of the box body 2, and a synchronous pulley 29 is provided at the output shaft end of the motor 18 and the surface of the column 28. When the motor 18 is started, the column 28 and the collecting pipe 3 on the column 28 are driven to rotate through the transmission belt 19, thereby driving the first collecting pipe 5, the second collecting pipe 6, the third collecting pipe 7 and the fourth collecting pipe 8 to rotate, and at the same time, the fan 10 is started, and gas is collected in sequence through the exhaust pipe 11, the connecting pipe 20, the column 28, the collecting pipe 3 and the pipe 9 connecting the first collecting pipe 5, the second collecting pipe 6, the third collecting pipe 7 and the fourth collecting pipe 8.

[0035] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 Two groups of bags 22 are symmetrically arranged on the top of the box body 2. The bottom of the bag 22 is connected to the air collecting box 16 through a spray pipe 24 with a solenoid valve. A liquid medicine storage tank 21 is provided on the box body 2, and the liquid medicine storage tank 21 is connected to the spray pipe 24; a liquid accumulation box 36 is provided on one side of the outer wall of the box body 2, and a drain pipe 35 is connected to the bottom of one side of the air collecting box 16, and the drain pipe 35 extends into the liquid accumulation box 36.

[0036] In this embodiment, a bag 22 and a medicine liquid storage tank 21 are provided on the top of the box body 2. By squeezing the bag 22, the medicine liquid in the medicine liquid storage tank 21 is sucked in. At the same time, the medicine liquid in the bag 22 is sprayed into the gas collecting box 16 through the spray pipe 24.

[0037] The housing 2 houses an air collecting box 16, which is used to purify the collected exhaust gas. At the bottom of the collection pipe 3, a first exhaust pipe 13 is arranged in an equidistant array in a circular pattern. These first exhaust pipes 13 are connected to valves 14. One end of these first exhaust pipes 13 is connected to a hollow ring 38, which is connected to the air collecting box 16. A positioning hole 30 is provided at the bottom of the air collecting box 16, and the hollow ring 38 is rotatably connected to the positioning hole 30 via a sealed bearing 15. An alloy tray 17 is centrally positioned horizontally within the air collecting box 16, with the first exhaust pipe 13 extending into the air collecting box 16 and positioned below the alloy tray 17.

[0038] In this embodiment, the valve 14 is opened, and the solenoid valve in the exhaust pipe 11 and the first gas collecting pipe 5, the second gas collecting pipe 6, the third gas collecting pipe 7 and the fourth gas collecting pipe 8 are all closed. The collected gas enters the gas collecting box 16 through the first exhaust pipe 13. An alloy tray 17 is provided in the gas collecting box 16. After the above-mentioned liquid medicine and gas are evenly distributed and fused on the alloy tray 17, the acidic molecules in the exhaust gas are neutralized by spraying the liquid medicine, and then the gas and liquid are separated by the alloy tray 17 to ensure the gas purification effect.

[0039] It should be noted that the first exhaust pipe 13 is connected to the collecting pipe 3 through a hollow ring 38, and the hollow ring 38 is rotatably installed in the positioning hole 30 through a sealing bearing 15, which can ensure that the first exhaust pipe 13 and the collecting pipe 3 are connected, and when the collecting pipe 3 rotates, it will not hinder the connection between the first exhaust pipe 13 and the air collecting box 16.

[0040] A top cover 27 is connected to the hollow ring 38 and is located above the exhaust port of the first exhaust pipe 13 via a support rod 39 . The top cover 27 is configured in a conical structure.

[0041] In this embodiment, since the first exhaust pipe 13 extends into the gas collecting box 16 and the opening is upward to facilitate the entry of gas into the gas collecting box 16, in order to prevent the spray liquid from entering the first exhaust pipe 13, a top cover 27 is provided above the first exhaust pipe 13. The top cover 27 is provided in a conical structure, the top of the top cover 27 is a cone tip, and the bottom diameter of the top cover 27 is larger than the outer diameter of the first exhaust pipe 13, which will not hinder the discharge of gas and can also prevent the spray liquid from entering the first exhaust pipe 13.

[0042] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 The outer wall of the collecting tube 3 is connected to a sleeve 25, the bottom surface of the sleeve 25 is provided with an inclined surface, one side of the inclined surface is connected to a top rod 26, the top of the bag 22 is connected to a top plate 23, the top plate 23 is provided with an arc-shaped plate structure, and the arc surface of the top plate 23 fits with the top rod 26.

[0043] In this embodiment, a sleeve 25 with an inclined surface is provided on the surface of the collecting tube 3. The sleeve 25 rotates with the collecting tube 3. A push rod 26 is connected to one side of the inclined surface of the sleeve 25. The push rod 26 can squeeze the bag 22 during the rotation. Specifically, when the push rod 26 moves to fit with the top plate 23 on the top of the bag 22, the bag 22 can be squeezed as it rotates. When the push rod 26 rotates away, the bag 22 is reset (technicians in this field can rotate elastic parts on both sides of the bag 22, and the bag can be reset after the downward pressure of the push rod 26 is lost). During the rotation, the top of the bag 22 is driven to rise and fall repeatedly, thereby achieving the effect of spraying the liquid medicine in the liquid medicine storage tank 21 into the gas collecting box 16 without manual or external air pump drive.

[0044] It should be noted that after the chemical liquid and the gas are separated, they drip to the bottom of the gas collecting box 16 and are discharged into the liquid storage box 36 through the drain pipe 35 to complete the recovery.

[0045] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9A dust collecting bag 31 is provided on the outer wall of the box body 2. The dust collecting bag 31 is connected to the air collecting box 16 through the second exhaust pipe 34. Springs 33 are connected to the four corners of the top of the dust collecting bag 31. Two sets of positioning plates 32 are connected to the outer wall of the box body 2. The springs 33 are connected to the bottom surface of the positioning plates 32.

[0046] In this embodiment, a dust collecting bag 31 is provided on the outer wall of the box body 2 to filter the purified gas. After the gas is discharged, the particulate matter therein can be collected by the dust collecting bag 31. In order to prevent the mesh of the dust collecting bag 31 from being blocked by particulate matter, a positioning plate 32 and a spring 33 are respectively provided between the box body 2 and the dust collecting bag 31. Under the impact of the gas flow, the dust collecting bag 31 can be shaken and connected to the outer wall of the box body 2 to achieve the above-mentioned effect, thereby ensuring the filtering effect of the dust collecting bag 31 on the gas.

[0047] A method of use includes a harmful gas monitoring device based on the treatment of spontaneous combustion waste rock piles, and the steps are as follows: Step 1: Collect the exhaust gas using the collection pipe 3 and the first collecting pipe 5, the second collecting pipe 6, the third collecting pipe 7 and the fourth collecting pipe 8 connected to the top of the collection pipe 3; Step 2: Use the sensor 37 in the gas chamber 12 to monitor the exhaust gas and obtain data on harmful gases; Step 3: Use the spray pipe 24 to treat the exhaust gas in the gas collecting box 16 and then discharge it.
