Description

Technical Field

[0001] This invention relates to the field of VOCs gas treatment technology, and in particular to an RTO waste gas treatment system. Background Technology

[0002] Regenerative thermal oxidation (RTO) is the mainstream process for treating VOCs today. It has the advantages of high efficiency, high thermal energy utilization efficiency and stable operation in VOCs purification. However, there are also certain risk factors in RTO purification of VOCs gas, such as large fluctuations in exhaust gas concentration and unstable exhaust gas volume, which pose certain hidden dangers to the safety of RTO system.

[0003] As a component of the RTO process, the RTO control logic plays a vital role in the safe operation of the RTO.

[0004] In existing technologies, RTO exhaust gas treatment systems typically only employ purging, heating, and reaction steps for treatment. This treatment method lacks solutions for handling malfunctions, has high costs, and lacks automated adjustment and adaptive means.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing control system structure. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The problem to be solved by the present invention is to provide an RTO exhaust gas treatment system to overcome the shortcomings of existing exhaust gas treatment systems, such as insufficient safety, lack of fault response solutions, high cost and lack of automation.

[0008] (II) Technical Solution

[0009] To address the aforementioned technical problem, a first aspect of the present invention provides an RTO waste gas treatment system, comprising:

[0010] The exhaust gas treatment module comprises two modules connected in parallel to the outside environment. Each exhaust gas treatment module includes an initial module, a purging module, a heating module, an air supply module, and an exhaust gas module. The initial module is the initial position of the exhaust gas treatment module. The purging module is used to purge the exhaust gas treatment module. The heating module is used to heat the exhaust gas treatment module. The air supply module is used to supply air to maintain the combustion temperature. The exhaust gas module is used to introduce the treated exhaust gas for further treatment.

[0011] Sensors are installed in the purging module, the heating module, the air supply module, and the exhaust gas module to monitor their internal data in real time.

[0012] The processing module receives and processes data from the exhaust gas treatment module. The processing module includes a pre-training block and a training module. The pre-training block generates a pre-training model for exhaust gas treatment based on external exhaust gas treatment information. The pre-training model is input into the training module, which gradually forms a training model based on on-site data. The processing module analyzes and processes various data from the exhaust gas treatment module based on the training model. When any sensor in the purging module, heating module, air supply module, or exhaust gas module detects abnormal data, the processing module stops the operation of the corresponding module and returns to the shutdown module, while another exhaust gas treatment module starts operating. When the heating module detects that the temperature exceeds a threshold range, the processing module controls the heating module to enter an energy-saving mode.

[0013] As described above in the RTO exhaust gas treatment system, optionally, the initial module is connected to the RTO cooling module. When the initial module is activated, the RTO cooling module is started, and the processing module intelligently controls the opening / closing of the RTO cooling module.

[0014] As described above in the RTO exhaust gas treatment system, optionally, the RTO cooling module and the heating module are connected to a semiconductor device. The semiconductor device has a cooling end and a heat dissipation end formed at both ends. The cooling end is connected to the RTO cooling module, and the heat dissipation end is connected to the heating module.

[0015] As described above, in the RTO exhaust gas treatment system, optionally, the processing module is connected to the cloud, which is used for monitoring, storing, and controlling the RTO exhaust gas treatment system.

[0016] As described above, in the RTO exhaust gas treatment system, optionally, the shutdown module, emergency module, and fault module are all connected to the initial module. When any of the shutdown module, emergency module, or fault module is triggered, the initial module starts and the exhaust gas treatment module returns to the initial stage.

[0017] As described above in the RTO exhaust gas treatment system, optionally, the purging module, the heating module, the air supply module, and the exhaust gas module are controlled sequentially, with each module having priority over the next.

[0018] As described above, in the RTO exhaust gas treatment system, optionally, the exhaust gas module is connected to the RTO treatment system, and the RTO treatment system is used to treat the exhaust gas after it has been treated by the exhaust gas treatment module.

[0019] As described above in the RTO exhaust gas treatment system, optionally, the processing module switches between the air supply module and the exhaust gas module as needed. When the exhaust gas module fails, the processing module switches the exhaust gas module to the air supply module.

[0020] As described above in the RTO exhaust gas treatment system, optionally, the energy-saving mode of the heating module is achieved through the coordinated action of the heat recovery unit and the insulation unit. The insulation unit is used to maintain a stable temperature. When the processing module detects that the temperature is too high, the heat recovery unit stores heat, and the heating module slows down the heat release efficiency until the temperature returns to the threshold range.

[0021] (III) Beneficial Effects

[0022] The RTO exhaust gas treatment system provided by this invention has the following beneficial effects:

[0023] This invention incorporates multiple sensors within a waste gas treatment module, working in conjunction with a processing module. The processing module receives, processes, and feeds back data from the sensors. Specifically, the processing module introduces an attention mechanism, along with a pre-training block and a training module. The pre-training block generates a pre-trained model of waste gas treatment based on external waste gas treatment information. This pre-trained model is input into the training module, which progressively develops a training model based on on-site data. The processing module then analyzes and processes the various data points within the waste gas treatment module using the training model, thereby enabling intelligent processing and real-time optimization of the waste gas treatment module's data.

[0024] This invention utilizes semiconductor devices to form both a heat-generating end and a cooling end. The heat-generating end is connected to a heating module, and the cooling end is connected to an RTO (Regenerative Thermal Oxidizer) cooling module. A single semiconductor device handles the processing of both the heating and RTO cooling modules. This design can save costs.

[0025] This invention includes a cloud platform, through which users can perform real-time monitoring. Attached Figure Description

[0035] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0036] See Figures 1 to 2 This invention provides an RTO (Regenerative Thermal Oxidizer) exhaust gas treatment system, comprising: two exhaust gas treatment modules 1 and a processing module 7. The processing module 7 receives data from the exhaust gas treatment modules 1, processes and judges the data in the exhaust gas treatment modules 1, and feeds back the results to the exhaust gas treatment modules 1. Specifically, the processing module 7 also has an attention mechanism, which, in conjunction with the pre-training block 8 and the training module 9, enables gradual adaptive improvement of the invention.

[0037] exist Figures 1 to 2 In an optional embodiment, there are two exhaust gas treatment modules 1, which are connected in parallel to the outside. Each exhaust gas treatment module 1 includes an initial module 2, a purging module 3, a heating module 4, an air supply module 5, and an exhaust gas module 6.

[0038] Specifically, the initial module 2 is the initial position of the exhaust gas treatment module 1, the purging module 3 is used to purge the exhaust gas treatment module 1, the heating module 4 is used to heat the exhaust gas treatment module 1, the air supply module 5 is used to supply air to maintain the combustion temperature, and the exhaust gas module 6 is used to introduce the treated exhaust gas for further treatment.

[0039] It should be noted that the purging module 3, heating module 4, air supply module 5, and exhaust gas module 6 are controlled sequentially, with each module having priority over the next. Specifically, in the steps of this invention, the initial module 2 is the initial position of the invention, and the purging module 3, heating module 4, air supply module 5, and exhaust gas module 6 act sequentially after the initial module 2 to complete the entire step operation and complete the treatment of the exhaust gas.

[0040] Among them, the exhaust gas may be, but is not limited to, VOCs gases.

[0041] Furthermore, sensors are installed in the purging module 3, heating module 4, air supply module 5, and exhaust gas module 6 to monitor their internal data in real time. The sensors can detect events during the reaction process and also control safety.

[0042] exist Figures 1 to 2 In an optional embodiment, the parking module 10, the emergency module 11, and the fault module 12 are all connected to the initial module 2. When any of the parking module 10, the emergency module 11, or the fault module 12 is triggered, the initial module 2 is started and the exhaust gas treatment module 1 returns to the initial stage.

[0043] Furthermore, the exhaust gas module 6 is connected to the RTO treatment system 13, which is used to treat the exhaust gas after it has been treated by the exhaust gas treatment module 1.

[0044] Furthermore, the initial module 2 is connected to the RTO cooling module 14. When the initial module 2 is activated, the RTO cooling module 14 starts, and the processing module 7 intelligently controls the opening and closing of the RTO cooling module 14. The RTO cooling module 14 can quickly cool the RTO exhaust gas treatment system after the reaction is completed, facilitating subsequent use.

[0045] Furthermore, the RTO cooling module 14 and the heating module 4 are connected to the semiconductor device. The semiconductor device has a cooling end and a heat dissipation end formed at both ends. The cooling end is connected to the RTO cooling module 14, and the heat dissipation end is connected to the heating module 4.

[0046] By using semiconductors, the cooling effect that can be achieved through heating can be reduced, thereby lowering costs.

[0047] This shows that when any of the parking module 10, emergency module 11, or fault module 12 is triggered, the system returns to the initial stage and issues an alarm to ensure safety, which can improve safety.

[0048] exist Figures 1 to 2 In an optional embodiment, the processing module 7 is used to receive and process data from the exhaust gas treatment module 1. The processing module 7 includes a pre-training block 8 and a training module 9. The pre-training block 8 generates a pre-training model for exhaust gas treatment based on external exhaust gas treatment information. The pre-training model is input into the training module 9. The training module 9 gradually forms a training model based on the field data. The processing module 7 analyzes and processes various data in the exhaust gas treatment module 1 based on the training model. When any sensor in the purging module 3, heating module 4, air supply module 5, or exhaust gas module 6 detects abnormal data, the processing module 7 stops the operation of the corresponding module and returns to the shutdown module 10, while another exhaust gas treatment module 1 starts operating. When the heating module 4 detects that the temperature exceeds the threshold range, the processing module 7 controls the heating module 4 to enter the energy-saving mode.

[0049] exist Figures 1 to 2 In an optional embodiment, the processing module 7 is connected to the cloud, which is used for monitoring, storing, and controlling the RTO exhaust gas treatment system. The cloud can be, but is not limited to, an app or a host platform.

[0050] Furthermore, the processing module 7 switches between the air supply module 5 and the exhaust gas module 6 as needed. When the exhaust gas module 6 fails, the processing module 7 switches the exhaust gas module 6 to the air supply module 5.

[0051] It should be noted that the switching between the exhaust gas module 6 and the air supply module 5 can effectively handle fault transmission, ensuring that exhaust gas does not accumulate in the system and completing emergency treatment.

[0052] Furthermore, the energy-saving mode of the heating module 4 works in concert with the heat recovery unit and the insulation unit. The insulation unit is used to maintain a stable temperature. When the processing module 7 detects that the temperature is too high, the heat recovery unit stores heat, and the heating module 4 slows down the heat release efficiency until the temperature returns to the threshold range, thereby improving the energy utilization rate.

[0053] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
