[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The terms "first" or "second," etc., used in this utility model to refer to numbers or ordinal numbers are for descriptive purposes only and should not be construed as indicating relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0024] like Figure 1-3 As shown in the figure, this utility model embodiment discloses an air intake device for separating chloride ions in coal gas, including an air intake and exhaust device 1, an inlet connecting pipe 2, an outlet connecting pipe 3, a separation device 4, and an absorbent liquid 7. One end of the inlet connecting pipe 2 is connected to the coal gas, and the other end of the inlet connecting pipe 2 is connected to the air inlet 611 of the separation device 4. One end of the outlet connecting pipe 3 is connected to the air outlet 621 of the separation device 4, and the other end of the outlet connecting pipe 3 is connected to the air intake and exhaust device 1. The absorbent liquid 7 is disposed inside the separation device 4.

[0025] To further explain, the suction and discharge device 1 can be a gas sampler, preferably an intelligent air / TSP sampler. This device uses an electronic flow meter and a microcomputer system to detect the sampling flow rate. It can automatically compensate for flow rate changes caused by voltage fluctuations, resistance, and temperature variations, and automatically calculate the cumulative sampling volume. After adsorbing the gas, the main unit 11 calculates the flow rate and discharges the gas outdoors. The inlet connection pipe 2 and the outlet connection pipe 3 can both be rubber hoses, plastic hoses, or metal hoses, preferably EPDM rubber hoses, which have excellent aging resistance, acid and alkali resistance, and flexibility. The hoses are directly fitted over the connection ports of each component. The main function of the separation device 4 is to fill the absorbent liquid 7. When the coal gas enters the separation device 4, it comes into contact with the absorbent liquid 7. The absorbent liquid 7 absorbs chloride ions from the coal gas, separating other gases. At this time, the intelligent air / TSP sampler starts to suck away the separated other gases, and the main unit 11 calculates the flow rate and discharges the gas outdoors. The absorbent 7 can be sodium hydroxide solution, sodium bicarbonate solution, or organic amine solution. Sodium bicarbonate solution is preferred because it absorbs chloride ions in coal gas better. The solution is less alkaline and less corrosive than NaOH. Regeneration can be achieved by releasing CO2 through heating.

[0026] Furthermore, the suction and discharge device 1 includes a main unit 11, a pressure flow meter 12, a power switch 15, an air intake 13 and an exhaust port 14. The pressure flow meter 12 is located on one side of the main unit 11, the power switch 15 is located on one side of the main unit 11, the air intake 13 is located on one side of the main unit 11, and the exhaust port 14 is located on the other side of the main unit 11.

[0027] To further explain, the main unit 11 is also equipped with a pump. When the power switch 15 starts the main unit 11, the pump draws the separated gas into the main unit 11 through the suction port 13. The flow rate of the gas is calculated by the pressure flow meter 12, and then the gas is discharged to the outside through the exhaust port 14. This avoids the separated gas from remaining in the separation device 4 or indoors.

[0028] Furthermore, a power module 16 is also provided on the other side of the host 11. One end of the power module 16 is connected to the other side of the host 11, and the other end of the power module 16 is connected to the mains power. The power module 16 is mainly used to supply power to the host 11 and provide electrical energy.

[0029] Furthermore, the separation device 4 includes a separation container 5 and a separation component 6, with the separation component 6 disposed within the separation container 5.

[0030] To further explain, the separation device 4 is configured as two components. The separation container 5 can be made of metal, plastic, or glass, but preferably of glass in a single stamping process, as it has excellent corrosion resistance. The separation container 5 is filled with absorbent liquid 7, and the opening at the top of the separation container 5 allows the separation component 6 to be assembled inside. The separation component 6 is also made of glass, and it is constructed by joining individual glass pieces at high temperature to achieve a seal at the joints. This allows the coal gas to enter the separation container 5 and react with the absorbent liquid 7 to adsorb chloride ions from the coal gas. The separated gas is then drawn away by the suction and discharge device 1 through the separation component 6, and the absorbent liquid 7 is then taken to the detection equipment for chloride ion detection.

[0031] Furthermore, the separation container 5 consists of a bottle body 51, a bottle mouth 52, and a bottle base 53. The lower end of the bottle body 51 is connected to the upper end of the bottle base 53, and the bottle mouth 52 is located at the upper end of the bottle body 51. The bottle body 51 is smaller than the bottle base 53. The bottle body 51, bottle mouth 52, and bottle base 53 are all circular. The bottle body 51 and bottle base 53 can be formed by high-temperature splicing or by integral glass stamping to form an internal space. The bottle base 53 is larger than the bottle body 51 for more stable and balanced placement. The bottle mouth 52 is smaller than the bottle body 51 and smaller than the largest outer wall of the separation cover 63 in the middle. The bottle mouth 52 is fitted over the separation cover 63, so that the largest outer wall of the separation cover 63 is stuck inside the bottle mouth 52.

[0032] Furthermore, the separation component 6 consists of an air inlet pipe 61, a separation cover 63, and an air outlet pipe 62. One end of the air inlet pipe 61 is connected to the other end of the air inlet connecting pipe 2, and the other end of the air inlet pipe 61 passes through the top opening of the separation cover 63 and is connected to the separation cover 63. The other end of the air inlet pipe 61 is located near the upper end of the bottle base 53. One end of the air outlet pipe 62 is connected to one side of the separation cover 63, and the other end of the air outlet pipe 62 is connected to the air inlet 13 through the air outlet connecting pipe 3.

[0033] To further explain, the main function of the inlet pipe 61 is to allow coal gas to enter the separation container 5. The outer wall of the inlet pipe 61 passes through the inlet pipe interface 631 at the top of the separation hood 63. The outer wall of the inlet pipe 61 is connected to the inner wall of the inlet pipe interface 631 of the separation hood 63 by high temperature, so that the interior of the inlet pipe 61 is separated from the separation hood 63. The other end of the inlet pipe 61 is close to the upper end of the bottle base 53. The separation hood 63 is configured as a U-shaped cover. The inlet pipe interface 631 is opened in the middle of the top of the separation hood 63. The inlet pipe interface 631 is connected to the outer wall of the inlet pipe 61. The top side of the separation hood 63 is provided with an outlet pipe interface 632, which is connected to one end of the outlet pipe 62. The lower end of the separation hood 63 is open, mainly to allow the separated gas to enter the separation hood 63 and be sucked away by the suction and discharge device 1 through the outlet pipe 62.

[0034] Furthermore, the top of the separation hood 63 is provided with an air inlet port 631 for easy connection to the air inlet port 61, and the side of the separation hood 63 near the top is provided with an air outlet port 632 for easy connection to the air outlet port 62. The lower end of the separation hood 63 is open, so that the separated gas can enter the air outlet port 62 from the lower end opening of the separation hood 63 and be sucked away.

[0035] Furthermore, a silicone sleeve is provided on the outer surface of the separation cover 63, which is fitted over the middle of the separation cover 63. The silicone sleeve is smaller than the outer wall of the separation cover 63, mainly to increase the friction and seal between the separation cover 63 and the bottle mouth 52, and to prevent gas from escaping due to insufficient sealing between the outer wall of the separation cover 63 and the inside of the bottle mouth 52.

[0036] Furthermore, the air inlet pipe 61 is composed of a first small pipe 612, an air inlet 611, a buffer chamber 64, a buffer pipe 613, an air outlet chamber 614, and an air outlet 615. The air inlet 611 is located at one end of the first small pipe 612, the buffer chamber 64 is located at one end of the first small pipe 612 near the air inlet 611, the other end of the first small pipe 612 passes through the air inlet pipe interface 631 and is connected to one end of the buffer pipe 613, the other end of the buffer pipe 613 is connected to the upper end of the air outlet chamber 614, and the air outlet 615 is located at the lower end of the air outlet chamber 614.

[0037] To further explain, the first small tube 612 is L-shaped, and the buffer chamber 64 can be circular, square, or polygonal. When the gas enters the buffer chamber 64, the gas is buffered and the pressure is reduced. The gas then continuously enters the buffer tube 613 through the first small tube 612, which further reduces the gas pressure. Finally, the gas flows into the outlet chamber 614 and enters the separation container 5 through several outlet holes 615 to contact the absorbent liquid 7. The buffer tube 613 is circular and larger than the first small tube 612. The components are fused together at the ends of the components at high temperature, and after cooling, they are stably connected together. The outlet holes 615 are located at the lower end of the outlet chamber 614 so that the coal gas can contact the absorbent liquid 7 from the bottom, allowing the absorbent liquid 7 to fully react and absorb the chloride ions in the coal gas. Other gases are separated, rise, and enter the space of the separation hood 63, and then are sucked away by the suction and discharge device 1 through the outlet pipe 62.

[0038] Furthermore, the vent pipe 62 is composed of a second small pipe 622, an vent 621 and a buffer chamber 64. The vent 621 is located at one end of the second small pipe 622, the buffer chamber 64 is located at one end of the second small pipe 622 near the vent 621, and the other end of the second small pipe 622 is connected to the vent pipe interface 632 on one side of the separation cover 63.

[0039] To further explain, the ports between the second small tube 622, the air outlet 621 and the buffer chamber 64 are connected by high-temperature fusion and then fixed after cooling. The other end of the second small tube 622 is connected to the air outlet interface 632 on one side of the separation cover 63, so that the air outlet 62 is connected to the separation cover 63, and the gas can flow from the separation cover 63 into the air outlet 62 and be sucked away.

[0040] The working principle of this utility model is as follows: First, the separation container 5 is filled with the absorption liquid 7. Then, the lower end of the separation component is passed through the bottle mouth of the separation container and enters the bottle body. Then, one end of the gas inlet connecting pipe 2 is connected to the gas, and the other end of the gas inlet connecting pipe 2 is connected to one end of the first small pipe 612. One end of the gas outlet connecting pipe 3 is connected to the second small pipe 522, and the other end of the gas outlet connecting pipe 3 is connected to the suction port 13 of the suction and discharge device 1. The gas enters the first small pipe 612 from the gas inlet connection pipe 2. At this time, the gas release pressure is too high. The buffer chamber 64 on the first small pipe 612 forms the first pressure relief space. The gas enters the buffer pipe 613 again through the first small pipe 612. At this time, the gas pressure is reduced for the second time. The gas is discharged into the separation container 5 from several gas outlet holes 615 on the gas outlet chamber 614 at the lower end of the buffer pipe 613, so that the gas can fully react and separate with the absorbent liquid 7. After the absorbent liquid 7 absorbs the chloride ions in the gas, other gases, such as hydrogen sulfide and other harmful gases, enter the separation hood 63 from the separation liquid 7. The separation hood is connected to the gas outlet pipe 61. At this time, the main unit 11 turns on the power switch 15 and starts to draw in gas. The main unit draws away other gases in the separation device 4 through the gas outlet connection pipe 3. After the pressure flow meter 12 calculates, the gas is discharged to the outside through the exhaust port 14. The suction and discharge device 1 can be set to adsorb for a specified time. When the adsorption reaches the specified time, it will automatically stop. The operator can then turn off the gas and take the separation device 4 to the testing machine to detect the chloride ions in the absorption liquid 7.

[0041] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
