[0002] During the production of sulfuric acid, SO2 gas needs to be converted into SO3 through a vanadium catalyst. The conversion efficiency of SO2 is related to the production efficiency of the sulfuric acid plant and the environmental protection emission of the tail gas. Therefore, during the production process of the sulfuric acid plant, it is necessary to measure the SO2 conversion rate every day to master the change of the conversion rate of the plant, measure the absorption efficiency of the absorption tower and the water content in the flue gas.

[0003] During each measurement, it is necessary to sample the flue gas from the sulfuric acid plant and introduce it into the detection device. The sampling of the flue gas is to sample the acidic gas in the sulfuric acid plant through an analysis sampling pipe. In order to ensure the effectiveness of the acidic gas, it is necessary to displace the remaining acidic gas in the sampling pipe before measurement. The 6 conversion rate measurement points are distributed around the converter. Before each analysis sampling, it is necessary to displace the sampling pipeline, and a large amount of unorganized acidic gas is discharged into the environment, causing great damage to the environment.

[0034] As Figures 1 to 5As shown in the figure, the embodiment of the utility model provides a closed sampler for the conversion rate of a sulfuric acid device, which includes a processing bin 1 whose interior is divided into a detection space 2 and a processing space 3. At the same time, a detection device 4 is fixedly installed on the inner wall of the detection space 2, and a controller 5 is fixedly installed on the surface of the processing bin 1, and the controller 5 is electrically connected to the detection device 4. Therefore, the user can control the start and stop states of the detection device 4 through the controller 5. Also, because a number of bellows 6 are fixedly penetrated through the surface of the processing bin 1, and a valve 7 is provided on each of the number of bellows 6, and one end of each of the number of bellows 6 is fixedly penetrated through the inner wall of the processing space 3. Therefore, after the user first connects one end of each of the number of bellows 6 to the inner wall of the number of air inlets of the detection device 4 through the connection mechanism 8, then the gas can be introduced into the detection device 4 through the number of bellows 6. After the detection device 4 finishes the detection, the detection device 4 will discharge the waste gas, which is sucked and purified by the purification mechanism 9. The main components of the detection device 4 are: a detection body 401 fixedly installed inside the detection space 2, and at the same time, a suction pump 402 is fixedly connected to each of the number of air inlets of the detection body 401. The main components of the connection mechanism 8 are: a number of installation pipes 801 respectively fixedly installed at one end of each of the number of bellows 6. When in use, the user rotates a number of connection pipes 802 respectively rotatably installed at one end of each of the number of installation pipes 801, and can thread each of the number of connection pipes 802 into the air inlet end of each of the number of suction pumps 402, so as to realize the connection between the number of bellows 6 and the detection body 401. The main components of the purification mechanism 9 are: a communication bin 901 fixedly penetrated through the surface of the processing bin 1, and a number of air inlet holes 902 are opened on the surface of the communication bin 901. At the same time, one of the air inlets is arranged inside the processing space 3 and a plug 903 is threadedly inserted into its inner wall. When in use, the user can generate negative pressure inside the communication bin 901 through the negative pressure processing mechanism 13, so as to suck the gas inside the processing bin 1 into the communication bin 901 and process the waste gas. It should be noted that: the number of air inlet holes 902 are distributed at multiple positions on the inner wall of the processing bin 1, and can fully suck the waste gas inside the processing bin 1. Also, because one of the air inlets is arranged inside the processing space 3 and a plug 903 is threadedly inserted into its inner wall, therefore, when in use, the user can generate negative pressure inside the communication bin 901 through the negative pressure processing mechanism 13, so as to suck the outside air into the communication bin 901 and then process the waste gas. After one detection is completed, the user removes the bellows 6 and closes the valve 7 on its surface. If there is a part of the waste gas remaining inside the bellows 6, the user can connect one end of the bellows 6 to the air inlet hole 902 arranged inside the detection space 2, and suck away and process the waste gas inside the bellows 6 through the negative pressure processing mechanism 13. When there is a part of the waste gas remaining inside the processing space 3, the user can rotate the two closing doors 14 and close the two closing doors 14.Then, the two closing doors 14 are limited by the limiting mechanism 15 on the inner wall of the processing space 3, so that most of the waste gas inside the processing space 3 can be isolated and extracted by the negative pressure pump 131. The main components of the negative pressure processing mechanism 13 are: the negative pressure pump 131 fixedly installed on the top of the processing chamber 1. During use, the user needs to turn on the negative pressure pump 131 through the controller 5, and the negative pressure pump 131 will apply negative pressure to the inside of the communication chamber 901 through the air inlet end. The surface of the processing chamber 1 is fixedly installed with a reaction chamber 132, and there is sodium hydroxide solution inside the reaction chamber 132. After the waste gas enters the inside of the reaction chamber 132, because the gas generated during the production of sulfur trioxide from sulfur dioxide has a density greater than that of air, it will sink and dissolve into the sodium hydroxide solution. The main components of the limiting mechanism 15 are: two latches 151 respectively fixedly installed on the surfaces of the two closing doors 14. During use, the user can respectively buckle the two latches 151 on the surfaces of the two fasteners 152 both fixedly installed on the surface of the processing chamber 1 to complete the limitation of the two closing doors 14.,

[0035] In the above solution, by setting a processing chamber 1 beside the sulfuric acid production device, during use, the user can pass the air outlet end of the sulfuric acid production device into the inside of several bellows 6 fixedly penetrating through the surface of the processing chamber 1. The gas entering the inside of the bellows 6 will enter the inside of the detection device 4, and the user can perform relevant detection operations. This is the prior art and will not be elaborated too much. After the detection is completed, the relevant detection data will be displayed on the controller 5. At the same time, after the detected gas is discharged, it will be sucked into the inside of the communication chamber 901 by the negative pressure processing mechanism 13 through several air inlet holes 902 for waste gas treatment operations, thus ensuring no gas leakage during the detection process.

[0036] In the above solution, after completing one detection, the user needs to close the valve 7 of the bellows 6, then remove the bellows 6 through the connection mechanism 8, and then rotate and remove the plug 903, and connect one end of the bellows 6 to the inner wall of the air inlet hole 902, so as to control the negative pressure processing mechanism 13 to suck out and treat the gas inside the bellows 6. Then open the valve 7, and the replacement of the waste gas inside the bellows 6 is completed, thus ensuring the timeliness of gas detection. At the same time, during the replacement process, the waste gas will not be lost in the air in large quantities. And even if some waste gas is lost inside the processing space 3, the user can close the two closing doors 14, limit the two closing doors 14 through the limiting mechanism 15, and then suck and treat the waste gas inside the processing space 3 through the negative pressure processing mechanism 13.

[0037] Such as Figure 2 and Figure 5As shown in the figure, an operation opening 10 is provided on the surface of the treatment chamber 1. An operation plane 11 is provided on the inner wall of the operation opening 10. The user can put his hand into the operation opening 10 to perform operations on the operation plane 11. And a flow meter 12 is provided on each of the several bellows 6. The user can receive the gas flow velocity inside each bellows 6 through the controller 5. It should be noted that: the part of the pipeline of the bellows 6 exposed outside the treatment chamber 1 is non-retractable and is made of metal. A valve 7 and a flow meter 12 are installed on its surface. At the same time, a professional sampler is installed at one end of this part of the pipeline. The user can perform professional sampling operations. The main components of the reaction chamber 132 are: a sealing cover 1322. At the same time, the main chamber body 1321 is fixedly installed on the surface of the treatment chamber 1. During use, the sealing cover 1322 can be first covered on the inner wall of the main chamber body 1321. Because the air outlet end of the negative pressure pump 131 is communicated with the sealing cover 1322, gas can be discharged from the air outlet end of the negative pressure pump 131 into the inside of the main chamber body 1321 and react with the sodium hydroxide solution inside the main chamber body 1321. When it is necessary to pull the two closing doors 14, the user can put his hand into the pulling grooves at the bottoms of the two closing doors 14 to pull the closing doors 14.

[0038] The working principle of the present utility model: First, the user introduces a gas into the inside of several bellows 6. The gas will enter the inside of the main chamber body 1321 and react with the sodium hydroxide solution, thereby completing the treatment of the waste gas. After a test is completed, even if there is some residual waste gas inside the bellows 6, the valve 7 can be closed, and one end of the bellows 6 can be communicated with the inner wall of one of the air inlet holes 902 to suck the waste gas. That is, after the gas in the intake pipeline of the device is subjected to a suction treatment by the detection device 4, a second more thorough treatment can be carried out.

[0039] Secondly, the user can respectively limit the two closing doors 14 through the connection between the lock catch 151 and the buckle 152. That is, the waste gas inside the treatment space 3 can also have a relatively closed space. Thus, when the bellows 6 leaks waste gas, the waste gas inside the treatment space 3 can be effectively sucked and treated.

[0040] The present utility model covers any alternatives, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
