Description

Technical Field

[0001] The present application provides an industrial tail gas centralized treatment system, method, device and readable storage medium, belonging to the technical field of tail gas treatment. Background Art

[0002] There are various operating equipment in modern industrial workshops, and the tail gases emitted by each piece of equipment are different. For example: 1) Some equipment emits gases containing substances such as benzene, alcohol, aldehyde, etc., and requires an activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system; 2) Some equipment emits gases containing acidic substances and requires an alkaline tail gas treatment system; 3) Some equipment emits gases containing malodorous gases such as ammonia and hydrogen sulfide and requires a UV photolysis air purification system; 4) Some equipment emits gases containing alkaline substances and requires an acidic tail gas treatment system; 5) Some equipment emits gases containing toxic substances and requires a direct combustion tail gas treatment system; 6) Some equipment emits gases containing a large amount of impurities and particulate matter and requires dust removal and particulate matter removal, and is treated by dry, wet, and electrostatic precipitation methods. There are also other substances in the gases emitted by other equipment, and corresponding tail gas treatment systems or devices are also required, which will not be elaborated here one by one.

[0003] However, at present, different tail gas treatment systems need to be used to purify the tail gases emitted by different equipment, which is time-consuming and laborious, and cannot be centrally and uniformly treated. Moreover, only when the tail gas treatment system is just put into use, the tail gas emitted is detected for compliance. However, as the use time of the tail gas treatment system increases, the problem of unqualified waste gas emissions may occur. If the tail gas emissions are to meet the standard requirements for a long time, an on-line real-time monitoring system needs to be installed in each tail gas treatment system, which is not economical. Summary of the Invention

[0004] In order to solve the problem that it is time-consuming and laborious to use different tail gas treatment systems to purify the tail gases emitted by different equipment in an industrial workshop, the present application proposes an industrial tail gas centralized treatment system, method, device and readable storage medium, which can centrally treat the tail gases emitted by various equipment.

[0005] The technical solution adopted by the present application is as follows: An industrial tail gas centralized treatment system includes: A gas detection device: used to detect the content, types and number of types of waste gases that need to be purified in the tail gas discharged from the waste gas discharge port; among them, chemical reactions, generation of toxic substances, corrosive substances or flammable and explosive phenomena cannot occur among the components of the waste gases discharged from each industrial equipment; A waste gas buffer device: used to send the waste gases discharged from each industrial equipment into the gas detection device, its input end is connected to the waste gas discharge ports of multiple industrial equipment, and its output end is connected to the gas detection device through a pipeline; Exhaust gas discharge device: used to discharge the exhaust gas that meets the emission standards, which is connected to the gas detection device through a pipeline; Several treatment units: used to purify the gases in the exhaust gas, and each treatment unit purifies and treats one type of gas. The treatment units are connected to each other through pipelines. At least two pipelines are provided between each treatment unit and the gas detection device to realize the circulating flow of the exhaust gas between the treatment unit and the gas detection device, so as to conduct multiple detections of the exhaust gas and judge whether it meets the emission standards; At least one valve is provided on each pipeline.

[0006] Furthermore, several gas detection instruments are provided in the gas detection device.

[0007] Furthermore, the industrial equipment connected to the exhaust gas buffer device at least includes high-temperature purification equipment and chemical vapor deposition equipment.

[0008] Furthermore, all valves are closed before the exhaust gas starts to be treated, and during the exhaust gas treatment process, it is ensured that only one pipeline is in the open state at the same time period.

[0009] Furthermore, the treatment unit is any one of the exhaust gas treatment systems or devices such as an alkaline exhaust gas treatment system, an activated carbon adsorption and desorption + catalytic combustion treatment system, a UV photolysis air purification system, an acidic exhaust gas treatment system, a direct combustion exhaust gas treatment system, an electric trapping exhaust gas treatment device, etc.

[0010] Furthermore, the control mode of the valve is unified manual control and / or automatic control through the industrial exhaust gas centralized treatment system.

[0011] Furthermore, the number of treatment units provided is the same as the number of types of exhaust gas discharged from the exhaust gas outlet, and the number of gas detection instruments provided is multiple single gas detection instruments corresponding to the number of types of exhaust gas, or the gas detection instrument uses a composite gas detection instrument that can detect multiple types of exhaust gas at the same time.

[0012] An industrial exhaust gas centralized treatment method includes the following steps: Step S1: Send the exhaust gas discharged from each industrial equipment into the exhaust gas buffer device. When centralized treatment of the exhaust gas is required, open the valve on the pipeline connecting the exhaust gas buffer device and the gas detection device to make the exhaust gas enter the gas detection device. After the exhaust gas entering the gas detection device meets the set value, close the valve on the pipeline connecting the exhaust gas buffer device and the gas detection device. At this time, the gas detection device detects the exhaust gas content, the types of exhaust gas and the number of types of exhaust gas, and judges whether each exhaust gas meets the emission standards; among them, chemical reactions, generation of toxic substances, corrosive substances or flammable and explosive phenomena cannot occur among the components of the exhaust gas discharged from each industrial equipment; Step S2: If it is detected that only one type of gas fails to meet the emission standard, send this type of gas into its corresponding treatment unit for purification, and then send the purified gas into the gas detection device again to detect whether it meets the emission standard. If the purified gas meets the emission standard, send the purified gas into the tail gas discharge device for emission. If the purified gas does not meet the emission standard, send this gas into its corresponding treatment unit again for purification; If it is detected that multiple types of gases all fail to meet the emission standard, send the mixed gas composed of these multiple types of gases through their corresponding multiple treatment units for purification one by one, and then send the purified gas into the gas detection device again to detect whether all types of gases in the waste gas have reached the emission standard. If all types of the purified gases meet the emission standard, send the purified waste gas into the tail gas discharge device for emission; if there is one type of gas in the purified mixed gas that fails to meet the emission standard, send the purified mixed gas into the treatment unit corresponding to the gas that fails to meet the emission standard for re-purification; if there are two or more types of gases in the purified mixed gas that fail to meet the emission standard, send the purified mixed gas through the treatment units corresponding to the gases that fail to meet the emission standard for re-purification in sequence, and so on in a cycle until all the gases after purification meet the emission standard and then send them into the tail gas discharge device for emission.

In the industrial tail gas centralized treatment system provided by this application, the gas detection device and the treatment unit cooperate with each other, and can centrally purify and detect the waste gas discharged from multiple different industrial equipment, ensuring that the tail gas discharged can still meet the emission standard after the treatment unit runs for a long time. There is no need to additionally install an on-line real-time monitoring system in the treatment unit, which simplifies the treatment system for purifying multiple types of tail gases and greatly improves the treatment efficiency of purifying multiple types of tail gases, having high economy; 2. For the industrial tail gas centralized treatment method provided by this application, it only needs to control the opening and closing of each valve according to the detection results of the gas detection instrument to realize the centralized treatment of the waste gas discharged from different equipment, and the operation process is simple. Description of the Drawings

[0016] The present application will be further described below with reference to the accompanying drawings: Figure 1 FIG. is a schematic structural diagram of an industrial waste gas centralized treatment system provided by an embodiment of the present application; Figure 2 FIG. is a schematic flow chart of an industrial waste gas centralized treatment method provided by an embodiment of the present application. Specific embodiments

[0017] As Figure 1 and 2 shown, the present application provides an industrial waste gas centralized treatment system, including a gas detection device, which is connected to an exhaust gas buffer device, an exhaust gas discharge device, and a plurality of treatment units. The exhaust gas buffer device is also connected to the exhaust gas outlets of various devices; A plurality of gas detection instruments are arranged in the gas detection device, which are used to detect the content, types, and number of types of waste gases that need to be purified in the waste gas discharged from multiple exhaust gas outlets; At least two pipelines are arranged between each treatment unit and the gas detection device, which are used to realize the circulating flow of the waste gas between the treatment unit and the gas detection device, realize the multiple detection of the waste gas, and judge whether it meets the emission standard. Each two treatment units are connected to each other through pipelines, and at least one valve is arranged on each pipeline. The gas detection device, the treatment unit, and a plurality of valves form a feedback loop.

[0018] Before designing different industrial waste gas centralized treatment systems, it is necessary to analyze the composition of different industrial waste gases and the reaction mechanism between them in advance to ensure that no chemical reactions occur between the components of each waste gas, no toxic substances, corrosive substances, or flammable and explosive substances are generated.

[0019] The number of treatment units is the same as the number of types of waste gases discharged from the exhaust gas outlet, that is, the number of treatment units is the same as the number of types of devices connected to the input end of the exhaust gas buffer device. When a single waste gas needs to be purified, the single waste gas is sent to its corresponding treatment unit for purification. When multiple types of waste gases need to be purified, the multiple types of waste gases are sequentially sent through their corresponding multiple treatment units for purification one by one. The purified waste gas is sent to the gas detection device to detect whether it meets the emission standard. If one or more types of waste gases do not meet the emission standard, the waste gas that does not meet the emission standard is sent to its corresponding treatment unit for re-purification. When all types of waste gases meet the emission standard, they are discharged.

[0020] The number of processing units is specifically set according to the types of waste gases that need to be centrally purified and treated in the factory workshop, ensuring that each processing unit and the gas detection device form a feedback loop. In this embodiment, it is assumed that there are two types of waste gases that need to be purified and treated, so two processing units and two gas detection instruments for detecting a single type of gas (or a multi-gas detection instrument) need to be set up.

[0021] The processing unit can be any one of the tail gas treatment systems or devices such as an alkaline tail gas treatment system, an activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system, a UV photolysis air purification system, an acidic tail gas treatment system, a direct combustion tail gas treatment system, an electric trapping tail gas treatment device, etc. The alkaline tail gas treatment system is used to treat tail gases containing acidic substances, the activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system is used to treat tail gases containing substances such as benzene, alcohol, aldehyde, etc., the UV photolysis air purification system is used to treat tail gases containing malodorous gases such as ammonia and hydrogen sulfide, the acidic tail gas treatment system is used to treat tail gases containing alkaline substances, the direct combustion tail gas treatment system is used to treat tail gases containing toxic substances, and the electric trapping tail gas treatment device is used to treat tail gases containing a large amount of impurities and particulate matter.

[0022] Specifically, as Figure 1 shown, the two processing units in the waste gas treatment system for treating two types of gases given in this embodiment are the A processing unit and the B processing unit respectively, and the gas detection instruments for detecting the two types of gases are the A gas detection instrument and the B gas detection instrument respectively; among them, the A processing unit is an alkaline tail gas treatment system, and the B processing unit is an activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system. The alkaline tail gas treatment system is the tail gas treatment system of a high-temperature purification equipment, and the activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system is the tail gas treatment system of a chemical vapor deposition equipment (hereinafter referred to as "CVD equipment"). The A gas detection instrument is selected according to the types of waste gases discharged from the high-temperature purification equipment, and the B gas detection instrument is selected according to the types of waste gases discharged from the CVD equipment.

[0023] There are 7 pipelines in this embodiment, namely Pipeline 1 - Pipeline 7. In this embodiment, a valve is provided at each of the inlet and outlet of each pipeline, that is, two valves are provided on each pipeline to prevent a valve from failing during long-term operation. The valves on Pipeline 1 are Valve A and Valve B respectively, the valves on Pipeline 2 are Valve C and Valve D respectively, the valves on Pipeline 3 are Valve E and Valve F respectively, the valves on Pipeline 4 are Valve G and Valve H respectively, the valves on Pipeline 5 are Valve I and Valve J respectively, the valves on Pipeline 6 are Valve K and Valve L respectively, and the valves on Pipeline 7 are Valve M and Valve N respectively. The gas detection device is connected to the input end of the A processing unit through Pipeline 1, and the gas detection device is connected to the output end of the A processing unit through Pipeline 2; the gas detection device is connected to the input end of the B processing unit through Pipeline 4, and the gas detection device is connected to the output end of the B processing unit through Pipeline 5; the purification end of the A processing unit is connected to the purification end of the B processing unit through Pipeline 3; the input end of the gas detection device is connected to the output end of the waste gas buffer device through Pipeline 6; the output end of the gas detection device is connected to the tail gas discharge device through Pipeline 7.

[0024] In this embodiment, the control mode of the valves is unified manual control and / or automatic control through the industrial tail gas centralized treatment system.

[0025] The tail gas discharge device in this embodiment is a chimney.

[0026] The alkaline tail gas treatment system, activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system, UV photolysis air purification system, acidic tail gas treatment system, direct combustion tail gas treatment system, electric trapping tail gas treatment device, etc. are all prior arts, and the application will not elaborate on their structures and principles, etc.

[0027] This application also provides an industrial tail gas centralized treatment method, which at least includes the following steps: Step S1: Send the waste gas discharged from each industrial equipment into the waste gas buffer device. When centralized treatment of the waste gas is required, open the valve on the pipeline connecting the waste gas buffer device and the gas detection device to allow the waste gas to enter the gas detection device. After the waste gas entering the gas detection device meets the set value, close the valve on the pipeline connecting the waste gas buffer device and the gas detection device. At this time, the gas detection device detects the waste gas content, waste gas types and the number of waste gas types, and judges whether each waste gas meets the emission standard. Among them, chemical reactions, generation of toxic substances, corrosive substances or flammable and explosive phenomena shall not occur among the components of the waste gas discharged from each industrial equipment.

[0028] In this embodiment, the exhaust gases discharged from multiple high-temperature purification equipment and CVD equipment flow into the exhaust gas buffer device through indoor pipelines. Then, two valves (K valve and L valve) on pipeline 6 are opened. After the exhaust gas in the exhaust gas buffer device enters the gas detection device through pipeline 6, the two valves (K valve and L valve) on pipeline 6 are closed. The A gas detection instrument and the B gas detection instrument work to detect the content, types, and number of types of exhaust gases that need to be purified in the exhaust gas.

[0029] Step S2: If it is detected that only one type of gas does not meet the emission standard, then send this type of gas into its corresponding treatment unit for purification. Send the purified gas into the gas detection device again to detect whether it meets the emission standard. If the purified gas meets the emission standard, send the purified gas into the tail gas discharge device for emission. If the purified gas does not meet the emission standard, send this gas into its corresponding treatment unit again for purification. If it is detected that multiple types of gases do not meet the emission standard, then sequentially pass the mixed gas composed of these multiple types of gases through their corresponding multiple treatment units for purification one by one. Send the purified gas into the gas detection device again to detect whether all types of gases in the exhaust gas have reached the emission standard. If all types of the purified gases meet the emission standard, send the purified exhaust gas into the tail gas discharge device for emission; if there is one type of gas in the purified mixed gas that does not meet the emission standard, send the purified mixed gas into the treatment unit corresponding to the gas that does not meet the emission standard for re-purification; if there are two or more types of gases in the purified mixed gas that do not meet the emission standard, sequentially pass the purified mixed gas through the treatment units corresponding to the gases that do not meet the emission standard for re-purification. Repeat this process until all the gases after purification reach the emission standard, and then send them into the tail gas discharge device for emission.

[0030] Specifically, Figure 2 For the process of treating two types of gases, A and B, in the industrial tail gas centralized treatment system as shown in Figure 1 The specific implementation principle is as follows: If only the A gas detector detects that the A gas in the waste gas does not meet the emission standard, then open the two valves (A valve and B valve) on pipeline 1. After the A gas enters the A treatment unit for purification, open the two valves (C valve and D valve) on pipeline 2. The purified A gas is sent into the gas detection device through pipeline 2, and the A gas detector detects whether it meets the emission standard. If the purified A gas meets the emission standard, then open the two valves (M valve and N valve) on pipeline 7. The purified A gas enters the tail gas discharge device through pipeline 7 and is discharged. If the purified A gas does not meet the emission standard, then open the two valves (A valve and B valve) on pipeline 1 again, and repeat the above treatment steps until the purified A gas meets the emission standard.

[0031] If only the B gas detector detects that the B gas in the waste gas does not meet the emission standard, then open the two valves (G valve and H valve) on pipeline 4. After the B gas enters the B treatment unit for purification through pipeline 4, open the two valves (I valve and J valve) on pipeline 5. The purified B gas enters the gas detection device through pipeline 5, and the B gas detector detects whether it meets the emission standard. If the purified B gas meets the emission standard, then open the two valves (M valve and N valve) on pipeline 7. The purified B gas enters the tail gas discharge device through pipeline 7 and is discharged. If the purified B gas does not meet the emission standard, then open the two valves (G valve and H valve) on pipeline 4 again, and repeat the above treatment steps until the purified B gas meets the emission standard and is discharged through the tail gas discharge device.

[0032] If the A gas detection instrument detects that the A gas in the waste gas exceeds the standard, and the B gas detection instrument detects that the B gas in the waste gas exceeds the standard, that is, when the waste gas that does not meet the emission standard contains both A gas and B gas, open the two valves (A valve and B valve) on pipeline 1. The A gas and B gas enter the A treatment unit simultaneously. After the A gas is purified, open the two valves (E valve and F valve) on pipeline 3. The B gas and the purified A gas enter the B treatment unit through pipeline 3 to purify the B gas. After purification, open the two valves (I valve and J valve) on pipeline 5. The purified A gas and B gas enter the gas detection device again through pipeline 5. The A gas detection instrument detects whether the purified A gas meets the emission standard, and the B gas detection instrument detects whether the purified B gas meets the emission standard.If both the purified gas A and gas B meet the emission standards, open the two valves (valve M and valve N) on pipeline 7 and discharge them through the tail gas discharge device; if the purified gas A meets the emission standards while the purified gas B does not, open the two valves (valve G and valve H) on pipeline 4, send the purified gas A and gas B into the B treatment unit for purification, after purifying gas B in the B treatment unit, open the two valves (valve I and valve J) on pipeline 5, send the secondary purified gas A and gas B into the gas detection device again, use the A gas detection instrument to detect whether the purified gas A meets the emission standards, and use the B gas detection instrument to detect whether the purified gas B meets the emission standards, repeat the above operations until both the purified gas A and gas B meet the emission standards, then open the two valves (valve M and valve N) on pipeline 7 and discharge the purified gas A and gas B through the tail gas discharge device; if the purified gas A does not meet the emission standards while the purified gas B meets the emission standards, open the two valves (valve A and valve B) on pipeline 1, send the purified gas A and gas B into the A treatment unit for purification, after purifying gas A in the A treatment unit, open the two valves (valve C and valve D) on pipeline 2, send the secondary purified gas A and gas B into the gas detection device again, use the A gas detection instrument to detect whether the purified gas A meets the emission standards, and use the B gas detection instrument to detect whether the purified gas B meets the emission standards, repeat the above operations until both the purified gas A and gas B meet the emission standards, then open the two valves (valve M and valve N) on pipeline 7 and discharge the purified gas A and gas B through the tail gas discharge device; if neither the purified gas A nor gas B meets the emission standards, open the two valves (valve A and valve B) on pipeline 1 again, gas A and gas B enter the A treatment unit simultaneously, after purifying gas A, open the two valves (valve E and valve F) on pipeline 3, send gas B and the purified gas A into the B treatment unit to purify gas B, after purification, open the two valves (valve I and valve J) on pipeline 5, send the purified gas A and gas B into the gas detection device again to respectively detect whether the purified gas A and gas B meet the emission standards, after meeting the emission standards, open the two valves (valve M and valve N) on pipeline 7 and discharge them through the tail gas discharge device, if they still do not meet the emission standards, repeat the above operations.

[0033] After all the gases discharged this time meet the emission standards and are discharged, open the two valves (valve K and valve L) on pipeline 6 again, send the waste gas in the waste gas buffer device into the gas detection device to detect the types and the number of types of gases contained in the waste gas, and repeat the above operations.

[0034] More specifically, before using the above industrial tail gas centralized treatment system to treat waste gas, ensure that all valves in the industrial tail gas centralized treatment system are in the closed state, and ensure that only one pipeline is in the open state during the same period of waste gas treatment.
