Description

Technical Field

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

[0002] There are many types of equipment running in modern industrial workshops, and each type of equipment emits different exhaust gases, such as: 1) The exhaust gases from some equipment contain substances such as benzene, alcohols, and aldehydes, which require an activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system; 2) The exhaust gases from some equipment contain acidic substances, which require an alkaline exhaust gas treatment system; 3) The exhaust gases from some equipment contain malodorous gases such as ammonia and hydrogen sulfide, which require a UV photolysis air purification system; 4) The exhaust gases from some equipment contain alkaline substances, which require an acidic exhaust gas treatment system; 5) The exhaust gases from some equipment contain toxic substances, which require a direct combustion exhaust gas treatment system; 6) The exhaust gases from some equipment contain a large amount of impurities and particulate matter, which require dust and particulate matter removal using dry, wet, or electrical capture methods. There are also other equipment that emit other substances and also require corresponding exhaust gas treatment systems or devices, which are not listed here.

[0003] However, at present, different exhaust gas treatment systems are required to purify the exhaust gas emitted by different equipment, which is time-consuming and labor-intensive, and cannot be handled in a centralized and unified manner. Moreover, the exhaust gas emitted can only be tested to see whether it meets the standards when the exhaust gas treatment system is just put into use. However, as the exhaust gas treatment system is used for a longer time, the problem of exhaust gas emissions not meeting the standards may occur. If it is to be ensured that the exhaust gas emissions meet the standards for a long time, an online real-time monitoring system needs to be installed in each exhaust gas treatment system, which is not economical. Summary of the Invention

[0004] In order to solve the problem that the exhaust gas emitted by different equipment in industrial workshops needs to be purified by different exhaust gas treatment systems, which is time-consuming and labor-intensive, this application proposes an industrial exhaust gas centralized treatment system, method, equipment and readable storage medium, which can centrally treat the exhaust gas emitted by multiple equipment.

[0005] The technical solution adopted in this application is: a centralized industrial tail gas treatment system, including:

[0006] Gas detection device: used to detect the content of waste gas that needs to be purified, the type of waste gas, and the number of waste gas types in the exhaust gas discharged from the exhaust outlet; the components of the waste gas discharged by various industrial equipment cannot chemically react with each other, cannot produce toxic or corrosive substances, and cannot produce flammable and explosive phenomena;

[0007] Exhaust gas buffer device: used to send exhaust gas discharged from various industrial equipment into the gas detection device. Its input end is connected to the exhaust gas outlets of multiple industrial equipment, and its output end is connected to the gas detection device through a pipeline;

[0008] Tail gas discharge device: used to discharge exhaust gas that meets emission standards, and is connected to the gas detection device through a pipeline;

[0009] Several processing units: used to purify the gas in the exhaust gas, and each processing unit purifies and treats a type of gas. The two processing units are connected by pipes. At least two pipes are set between each processing unit and the gas detection device to realize the circulation of exhaust gas between the processing unit and the gas detection device, realize multiple detection of exhaust gas, and judge whether it meets the emission standards;

[0010] Each pipeline is provided with at least one valve.

[0011] Furthermore, the gas detection device is provided with a plurality of gas detection instruments.

[0012] Furthermore, the industrial equipment connected to the exhaust gas buffer device includes at least high-temperature purification equipment and chemical vapor deposition equipment.

[0013] Furthermore, all valves are closed before the waste gas treatment begins, ensuring that only one pipe is open at any one time during the waste gas treatment process.

[0014] Furthermore, the treatment unit is any one of the exhaust gas treatment systems or devices including alkaline exhaust gas treatment system, activated carbon adsorption and desorption + catalytic combustion treatment system, UV photolysis air purification system, acidic exhaust gas treatment system, direct combustion exhaust gas treatment system, and electric capture exhaust gas treatment device.

[0015] Furthermore, the valve is controlled by a centralized industrial tail gas treatment system through manual control and / or automatic control.

[0016] Furthermore, the number of processing units set is consistent with the number of exhaust gas types discharged from the exhaust outlet, and the number of gas detection instruments set is multiple single gas detection instruments corresponding to the number of exhaust gas types, or the gas detection instrument uses a composite gas detection instrument that can simultaneously detect multiple exhaust gas types.

[0017] A method for centralized treatment of industrial tail gas comprises the following steps:

[0018] Step S1: The waste gas discharged by each industrial equipment is sent to the waste gas buffer device. When the waste gas needs to be centrally treated, the valve on the pipe connecting the waste gas buffer device and the gas detection device is opened to allow the waste gas to enter the gas detection device. After the waste gas entering the gas detection device meets the set value, the valve on the pipe connecting the waste gas buffer device and the gas detection device is closed. At this time, the gas detection device detects the waste gas content, waste gas type and number of waste gas types, and determines whether each waste gas meets the emission standard; wherein the components of the waste gas discharged by each industrial equipment cannot chemically react with each other, cannot produce toxic or corrosive substances, and cannot produce flammable and explosive phenomena;

[0019] Step S2: If it is detected that only one type of gas does not meet the emission standard, the gas of this type is sent to the corresponding processing unit for purification treatment, and the purified gas is sent to the gas detection device again to detect whether it meets the emission standard. If the purified gas meets the emission standard, the purified gas is sent to the exhaust gas discharge device for discharge. If the purified gas does not meet the emission standard, the gas is sent to the corresponding processing unit again for purification treatment;

[0020] If it is detected that multiple types of gases do not meet the emission standards, the mixed gas composed of the multiple types of gases will be purified one by one in turn through the corresponding multiple processing units, and the purified gas will be sent to the gas detection device again to detect whether all types of gases in the exhaust gas have met the emission standards. If multiple types of gases after purification meet the emission standards, the purified exhaust gas will be sent to the tail gas exhaust device for discharge; if one type of gas in the purified mixed gas does not meet the emission standards, the purified mixed gas will be sent to the processing unit corresponding to the gas that does not meet the emission standards for purification again; if two or more types of gases in the purified mixed gas do not meet the emission standards, the purified mixed gas will be passed through the processing units corresponding to the gases that do not meet the emission standards for purification again in turn, and this cycle will be repeated until all gases after purification meet the emission standards and are sent to the tail gas exhaust device for discharge.

[0023] The beneficial effects of this application compared to the prior art are:

[0024] 1. The gas detection device and the treatment unit in the centralized industrial exhaust gas treatment system provided by this application cooperate with each other to centrally purify and detect exhaust gases emitted by various industrial equipment. This ensures that the exhaust gases emitted can still meet emission standards after the treatment unit has been running for a long time. There is no need to install an online real-time monitoring system in the treatment unit. This simplifies the treatment system for purifying and treating multiple types of exhaust gases, greatly improves the treatment efficiency of purifying and treating multiple types of exhaust gases, and has high economic efficiency.

[0025] 2. The centralized treatment method for industrial tail gas provided in this application only needs to control the opening and closing of each valve according to the detection results of the gas detection instrument to achieve centralized treatment of the exhaust gas discharged by different equipment, and the operation process is simple.

[0026] The present application will be further described below with reference to the accompanying drawings:

[0027] Figure 1 This is a schematic diagram of the structure of a centralized industrial tail gas treatment system according to an embodiment of the present application;

[0028] Figure 2 This is a flow chart of a centralized industrial tail gas treatment method according to an embodiment of the present application. DETAILED DESCRIPTION

[0029] like Figure 1 and 2 As shown, the present application provides an industrial exhaust centralized treatment system, including a gas detection device, the gas detection device is connected to an exhaust gas buffer device, an exhaust gas discharge device and several processing units, and the exhaust gas buffer device is also connected to the exhaust gas outlets of various devices;

[0030] The gas detection device is provided with a number of gas detection instruments for detecting the content of waste gas that needs to be purified, the type of waste gas and the number of waste gas types in the exhaust gas discharged from multiple exhaust gas outlets;

[0031] At least two pipes are set between each processing unit and the gas detection device to realize the circulation of exhaust gas between the processing unit and the gas detection device, realize multiple detection of exhaust gas, and judge whether it meets the emission standards. The two processing units are connected to each other through pipes, and each pipe is provided with at least one valve. The gas detection device, processing unit and multiple valves constitute a feedback loop.

[0032] Before designing centralized treatment systems for different industrial exhaust gases, it is necessary to analyze in advance the components of different industrial exhaust gases and their reaction mechanisms to ensure that no chemical reactions occur between the exhaust gas components, no toxic or corrosive substances are produced, and no flammable or explosive problems occur.

[0033] The number of treatment units is consistent with the number of types of exhaust gas discharged from the exhaust outlet, that is, the number of treatment units is consistent with the number of types of equipment connected to the input end of the exhaust gas buffer device. When a single exhaust gas needs to be purified, it is sent to its corresponding treatment unit for purification. When multiple types of exhaust gas need to be purified, the multiple types of exhaust gas are sequentially purified one by one through the corresponding multiple treatment units. The purified exhaust gas is sent to a gas detection device to detect whether it meets the emission standards. If one or more types of exhaust gas do not meet the emission standards, the exhaust gas that does not meet the emission standards is sent to the corresponding treatment unit for further purification. When all types of exhaust gas meet the emission standards, they are discharged.

[0034] The number of processing units is determined by the type of exhaust gas that requires centralized purification in the factory workshop, ensuring that each processing unit forms a feedback loop with the gas detection device. In this embodiment, assuming that exhaust gas containing two types of gases needs to be purified, two processing units and two gas detection devices capable of detecting a single type of gas (or an all-in-one gas detection device) are required.

[0035] The treatment unit can be any of the following tail gas treatment systems or devices: 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 capture tail gas treatment device, etc. The alkaline tail gas treatment system is used to treat tail gas containing acidic substances, the activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system is used to treat tail gas containing substances such as benzene, alcohols, and aldehydes, the UV photolysis air purification system is used to treat tail gas containing malodorous gases such as ammonia and hydrogen sulfide, the acidic tail gas treatment system is used to treat tail gas containing alkaline substances, the direct combustion tail gas treatment system is used to treat tail gas containing toxic substances, and the electric capture tail gas treatment device is used to treat tail gas containing large amounts of impurities and particulate matter.

[0036] Specifically, such as Figure 1 As shown, the two processing units in the exhaust gas treatment system for treating two types of gases provided in this embodiment are respectively processing unit A and processing unit B, and the gas detection instruments for detecting the two types of gases are respectively gas detection instrument A and gas detection instrument B; wherein processing unit A is an alkaline exhaust gas treatment system, and processing unit B is an activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system. The alkaline exhaust gas treatment system is an exhaust gas treatment system for high-temperature purification equipment, and the activated carbon adsorption and desorption + catalytic combustion (RCO) treatment system is an exhaust gas treatment system for chemical vapor deposition equipment (hereinafter referred to as "CVD equipment"). Gas detection instrument A is selected according to the type of exhaust gas discharged by the high-temperature purification equipment, and gas detection instrument B is selected according to the type of exhaust gas discharged by the CVD equipment.

[0037] In this embodiment, there are seven pipelines, namely pipelines 1 to 7. In this embodiment, a valve is installed at the entrance and exit of each pipeline, that is, two valves are installed on each pipeline to prevent a valve from failing during long-term operation. The valves on pipeline 1 are valve A and valve B, the valves on pipeline 2 are valve C and valve D, the valves on pipeline 3 are valve E and valve F, the valves on pipeline 4 are valve G and valve H, the valves on pipeline 5 are valve I and valve J, the valves on pipeline 6 are valve K and valve L, and the valves on pipeline 7 are valve M and valve N. The gas detection device is connected to the input end of processing unit A through pipeline 1, and the gas detection device is connected to the output end of processing unit A through pipeline 2; the gas detection device is connected to the input end of processing unit B through pipeline 4, and the gas detection device is connected to the output end of processing unit B through pipeline 5; the purification end of processing unit A is connected to the purification end of processing unit B through pipeline 3; the input end of the gas detection device is connected to the output end of the exhaust gas buffer device through pipeline 6; and the output end of the gas detection device is connected to the exhaust gas exhaust device through pipeline 7.

[0038] In this embodiment, the valve is controlled by a centralized industrial tail gas treatment system through manual control and / or automatic control.

[0039] The exhaust gas discharge device in this embodiment is a chimney.

[0040] Alkaline exhaust gas treatment systems, activated carbon adsorption and desorption + catalytic combustion (RCO) treatment systems, UV photolysis air purification systems, acidic exhaust gas treatment systems, direct combustion exhaust gas treatment systems, and electric capture exhaust gas treatment devices are all existing technologies, and this application will not elaborate on their structures and principles.

[0041] The present application also provides a method for centralized treatment of industrial tail gas, comprising at least the following steps:

[0042] Step S1: Exhaust gas from each industrial device is fed into an exhaust gas buffer. When the exhaust gas needs to be centrally processed, the valve on the pipe connecting the exhaust gas buffer and the gas detection device is opened, allowing the exhaust gas to enter the gas detection device. After the exhaust gas entering the gas detection device meets the set value, the valve on the pipe connecting the exhaust gas buffer and the gas detection device is closed. The gas detection device then detects the exhaust gas content, exhaust gas type, and number of exhaust gas types, and determines whether each exhaust gas meets the emission standards. The components of the exhaust gas discharged by each industrial device must not chemically react with each other, produce toxic or corrosive substances, or cause flammability or explosion.

[0043] In this embodiment, the waste gas discharged from multiple high-temperature purification equipment and CVD equipment flows into the waste gas buffer device through indoor pipes, and then the two valves (K valve and L valve) on pipe 6 are opened. The waste gas in the waste gas buffer device enters the gas detection device through pipe 6 and then the two valves (K valve and L valve) on pipe 6 are closed. Gas detection instrument A and gas detection instrument B work to detect the content of waste gas that needs to be purified, the type of waste gas and the number of waste gas types in the waste gas.

[0044] Step S2: If it is detected that only one type of gas does not meet the emission standard, the gas of this type is sent to the corresponding processing unit for purification treatment, and the purified gas is sent to the gas detection device again to detect whether it meets the emission standard. If the purified gas meets the emission standard, the purified gas is sent to the exhaust gas discharge device for discharge. If the purified gas does not meet the emission standard, the gas is sent to the corresponding processing unit again for purification treatment;

[0045] If it is detected that multiple types of gases do not meet the emission standards, the mixed gas composed of the multiple types of gases will be purified one by one in turn through the corresponding multiple processing units, and the purified gas will be sent to the gas detection device again to detect whether all types of gases in the exhaust gas have met the emission standards. If multiple types of gases after purification meet the emission standards, the purified exhaust gas will be sent to the tail gas exhaust device for discharge; if one type of gas in the purified mixed gas does not meet the emission standards, the purified mixed gas will be sent to the processing unit corresponding to the gas that does not meet the emission standards for purification again; if two or more types of gases in the purified mixed gas do not meet the emission standards, the purified mixed gas will be passed through the processing units corresponding to the gases that do not meet the emission standards for purification again in turn, and this cycle will be repeated until all gases after purification meet the emission standards and are sent to the tail gas exhaust device for discharge.

[0046] Specifically, Figure 2 For example Figure 1 The process of treating gases A and B in the centralized industrial tail gas treatment system shown in the figure is implemented as follows:

[0047] If only the A gas detection instrument detects that the A gas in the exhaust gas does not meet the emission standards, the two valves on pipeline 1 (A valve and B valve) are opened, and the A gas enters the A treatment unit for purification. Then, the two valves on pipeline 2 (C valve and D valve) are opened, and the purified A gas is sent to the gas detection device through pipeline 2, and is detected by the A gas detection instrument to see whether it meets the emission standards. If the purified A gas meets the emission standards, the two valves on pipeline 7 (M valve and N valve) are opened, and the purified A gas enters the exhaust device through pipeline 7 and is discharged. If the purified A gas does not meet the emission standards, the two valves on pipeline 1 (A valve and B valve) are opened again, and the above processing steps are repeated until the purified A gas meets the emission standards.

[0048] If only the B gas detection instrument detects that the B gas in the exhaust gas does not meet the emission standards, the two valves on pipe 4 (G valve and H valve) are opened, and the B gas enters the B treatment unit through pipe 4 for purification. After that, the two valves on pipe 5 (I valve and J valve) are opened, and the purified B gas enters the gas detection device through pipe 5. The B gas detection instrument detects whether it meets the emission standards. If the purified B gas meets the emission standards, the two valves on pipe 7 (M valve and N valve) are opened, and the purified B gas enters the tail gas exhaust device through pipe 7 and is discharged. If the purified B gas does not meet the emission standards, the two valves on pipe 4 (G valve and H valve) are opened again, and the above processing steps are repeated until the purified B gas meets the emission standards and is discharged through the tail gas exhaust device.

[0049] If gas detection instrument A detects that gas A in the exhaust gas exceeds the standard, and gas detection instrument B detects that gas B in the exhaust gas exceeds the standard, that is, the exhaust gas that does not meet the emission standards contains both gas A and gas B, open the two valves on pipeline 1 (valve A and valve B), and gas A and gas B enter the A treatment unit at the same time. After purifying gas A, open the two valves on pipeline 3 (valve E and valve F), and gas B and the purified gas A enter the B treatment unit through pipeline 3 to purify gas B. After purification, open the two valves on pipeline 5 (valve I and valve J), ​​and the purified gas A and gas B enter the gas detection device again through pipeline 5. Gas detection instrument A detects whether the purified gas A meets the emission standards, and gas detection instrument B detects whether the purified gas B meets the emission standards.If the purified gas A and gas B meet the emission standards, open the two valves (M valve and N valve) on pipeline 7 and discharge them through the tail gas exhaust device; if the purified gas A meets the emission standards and the purified gas B does not meet the emission standards, open the two valves (G valve and H valve) on pipeline 4 and send the purified gas A and gas B to the B treatment unit for purification. After the B treatment unit purifies the gas B, open the two valves (I valve and J valve) on pipeline 5 and send the secondary purified gas A and gas B to the gas detection device again. The gas A detection instrument detects the purified gas A. Whether the gas meets the emission standard, the B gas detection instrument detects whether the purified B gas meets the emission standard. Repeat the above operation until the purified A gas and B gas meet the emission standard, then open the two valves (M valve and N valve) on pipeline 7 to discharge the purified A gas and B gas through the tail gas discharge device; if the purified A gas does not meet the emission standard, but the purified B gas meets the emission standard, then open the two valves (A valve and B valve) on pipeline 1 to send the purified A gas and B gas into the A processing unit for purification. After the A processing unit purifies the A gas, open pipeline 2 The two valves on the pipe (valve C and valve D) are opened to send the secondary purified gas A and gas B into the gas detection device again. The gas detection instrument A detects whether the purified gas A meets the emission standard. The gas detection instrument B detects whether the purified gas B meets the emission standard. The above operation is repeated until the purified gas A and gas B meet the emission standard. Then, the two valves on the pipe 7 (valve M and valve N) are opened to discharge the purified gas A and gas B through the tail gas discharge device. If the purified gas A and gas B do not meet the emission standard, the two valves on the pipe 1 (valve A) are opened again. Valve and valve B), gas A and gas B enter the A processing unit at the same time. After gas A is purified, the two valves on pipeline 3 (valve E and valve F) are opened, and gas B and the purified gas A are sent to the B processing unit for purification of gas B. After purification, the two valves on pipeline 5 (valve I and valve J) are opened, and the purified gas A and gas B are sent to 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, the two valves on pipeline 7 (valve M and valve N) are opened to discharge through the exhaust device. If the emission standards are still not met, repeat the above operations.

[0050] When all the gas discharged this time meets the emission standards, open the two valves (K valve and L valve) on pipeline 6 again, and send the waste gas in the waste gas buffer device to the gas detection device to detect the type and number of gases contained in the waste gas, and repeat the above operation.

[0051] More specifically, before using the above-mentioned centralized industrial exhaust gas treatment system to treat waste gas, ensure that all valves in the centralized industrial exhaust gas treatment system are in a closed state, and during the waste gas treatment process, ensure that only one pipeline is in an open state at the same time period.

[0052] The present application also provides a computer device, including a memory and a processor, wherein the memory is used to store a computer program, and the processor is used to implement the steps of the above-mentioned method for centralized treatment of industrial exhaust gas when executing the computer program.
