[0002] As a mainstream waste treatment method at present, the storage capacity of waste in a general waste incineration power plant can be as high as tens of thousands of tons. A large amount of combustible gas, such as methane, will be generated when such a large amount of waste is stored in a closed waste pit. When the concentration of combustible gas reaches a certain level, an explosion is likely to occur. If these combustible gases cannot be properly treated, it will bring great safety hazards to the waste power plant. Therefore, corresponding explosion-proof measures need to be taken for such safety hazards.

[0048] The following will be described in detail below with reference to the accompanying Figure 1 - the accompanying Figure 6 , the present application will be further described in detail.

[0049] The present application provides an explosion-proof system for a waste incineration power plant, referring to Figure 1 , the system comprises a gas concentration detection module 10, a gas flow control module 20 and a service terminal 30.

[0050] Among them, the service terminal 30 is in communication connection with the gas concentration detection module 10 and the gas flow control module 20.

[0051] The gas concentration detection module 10 is configured to detect the concentration of the combustible gas in the garbage pool and the leachate collection pool to obtain a concentration detection result.

[0052] The gas flow control module 20 is configured to control the flow of the gas between the leachate collection pool, the garbage pool and the incinerator according to the concentration detection result.

[0053] The service terminal 30 is configured to redefine the safety concentration threshold before controlling the flow of the gas according to the concentration detection result fed back by the gas concentration detection module, generate a control instruction according to the safety concentration threshold, and send the control instruction to the gas flow control module.

[0054] In the embodiment of the present application, for a garbage incineration power plant, garbage will be accumulated in a fixed place before entering the incinerator, that is, the collected garbage will be stored in a garbage pool. Before incineration, the garbage in the garbage pool will be fully fermented, and combustible gas such as biogas will be generated in the process of fermentation. The main components of the biogas are methane and carbon dioxide, in addition to ammonia and hydrogen sulfide and other foul-smelling and toxic gases, which may pose an explosion risk or directly harm the human body.

[0055] In addition, part of the garbage with a high water content will produce liquid, i.e. leachate, after being stacked and extruded, which will be discharged to the leachate collection pool. Since the leachate collection pool has a heavy odor, in order to prevent pollution of the surrounding environment, the leachate collection pool will usually be used as a closed container. The gas in the leachate collection pool will be sent to the garbage pool by an exhaust fan, mixed with the gas in the garbage pool, and then sucked away by a boiler exhaust fan to participate in garbage incineration.

[0056] Since combustible gas will be present in both the garbage pool and the leachate collection pool, and these combustible gases are prone to explode when reaching a certain concentration, it is necessary to detect the concentration of the combustible gas.

[0057] Therefore, in the embodiment of the present application, the gas concentration detection module 1 is first used to detect the concentration of the combustible gas in the garbage pool and the leachate collection pool to obtain a concentration detection result.

[0058] Specifically, referring to Figure 2 , the gas concentration detection module 10 includes a real-time detection unit 101, an information feedback unit 102, a data receiving unit 103 and an abnormality warning unit 104.

[0059] The real-time detection unit 101 is configured to detect the type of gas and the corresponding concentration value in the garbage pool and the leachate collection pool in real time.

[0060] The information feedback unit 102 is configured to feed back the detected gas type and corresponding concentration value information to the service terminal 30.

[0061] The data receiving unit 103 is configured to receive the safety concentration threshold value sent by the service terminal.

[0062] The abnormality warning unit 104 is configured to determine whether the gas concentration in the current space exceeds the safety concentration threshold value according to the safety concentration threshold value, and issue an alarm prompt if the safety concentration threshold value is exceeded.

[0063] Since the combustible gas includes different types of gas, such as methane, hydrogen sulfide, etc., when detecting the gas concentration, corresponding concentration values are given for different types of gas, that is, the type of gas and the corresponding concentration value in the garbage pit and the leachate collection pit are first detected in real time by the real-time detection unit 101, for example, a point-type combustible gas detector JTQB-BK61Ex-LCD is used, which has a measurement range of 0-100% LEL (LEL: lower explosive limit concentration of flammable gas), and is installed in the garbage pit and the leachate collection pit, which can display the type of gas and the corresponding gas concentration value in the two spaces in real time.

[0064] No matter for the garbage pit or the leachate collection pit, the concentration of the combustible gas will have a safety concentration threshold value, and the safety concentration threshold values of different types of gas are different, for example, the concentration range of methane explosion is generally between 5%-15%, that is, the minimum safety concentration is about 5% VOL, and the alarm parameter of methane is generally set to 10% LEL, that is, the corresponding concentration value is 0.5% VOL, that is, when the methane concentration in the space is 0.5% VOL, it means that there is a hidden danger.

[0065] When the combustible gas is detected in real time, an alarm prompt will be given according to the pre-set safety concentration threshold value, that is, an alarm prompt will be given when the corresponding alarm parameter is reached, that is, the abnormality warning unit 104 is used to determine whether the gas concentration in the current space exceeds the safety concentration threshold value according to the safety concentration threshold value, and an alarm prompt will be given if the safety concentration threshold value is exceeded.

[0066] Since the gas in the leachate collection pit is sent to the garbage pit by the exhaust fan, then mixed with the gas in the garbage pit, and then sucked into the incinerator by the suction fan to participate in garbage incineration, so here involves two times of space flow of gas, one is from the leachate collection pit to the garbage pit, and the other is the mixed gas flowing to the incinerator.

[0067] Before the space gas flow, will be according to the respective type of gas safety concentration threshold as a warning, but when two space gas mixing, the concentration of each type of gas is likely to have a mutation, this time the mutation of gas concentration may exceed the original space under the gas concentration, this case is easy to appear larger security risks.

[0068] Therefore, in the embodiment of the application, before the gas space flow, the concentration of mixed gas after flow is measured, and then it is judged whether to adjust the safety concentration threshold again to ensure that the concentration of the gas after flow is still in a safe range, and then the gas flow is carried out.

[0069] Therefore, the concentration detection result of the combustible gas by the real-time detection unit 101 is synchronized to the service terminal 30, and the service terminal 30 measures the state of the mixed gas in two spaces to adjust the safety concentration threshold again, that is, the detected gas type and corresponding concentration value information are fed back to the service terminal 30 through the information feedback unit 102, then the safety concentration threshold sent by the service terminal 30 is received by the data receiving unit 103, and finally the new safety concentration threshold is used as a reference standard for whether the gas flow can be carried out.

[0070] Since the space flow of the gas is carried out by the exhaust fan or the air suction fan and the like, there is a corresponding control strategy for when to start the exhaust or air suction, that is, the control instruction is given by the service terminal 30, and the specific implementation is carried out by the gas flow control module 20.

[0071] Therefore, in the embodiment of the application, the gas flow control module 20 is used to control the flow of the gas between the leachate collection pool, the garbage pool and the incinerator according to the concentration detection result.

[0072] Specifically, referring to Figure 3 , the gas flow control module 20 includes an information receiving unit 201, a gas mixing unit 202 and a gas incineration unit 203.

[0073] The information receiving unit 201 is used to receive the control instruction information fed back by the service terminal 30.

[0074] The gas mixing unit 202 is used to send the gas in the leachate collection pool into the garbage pool according to the received control instruction information.

[0075] The gas incineration unit 203 is used to send the mixed gas in the garbage pool into the incinerator according to the received control instruction information.

[0076] The above-mentioned space transfer of gas is divided into two stages, one is from the leachate collection tank to the landfill tank, and the other is from the mixed gas in the landfill tank to the incinerator. When the service terminal 30 confirms that the gas concentration is still within a safe range after the space transfer of gas according to the concentration detection result fed back by the gas concentration detection module 10, the space transfer of gas is allowed to proceed.

[0077] Therefore, when the current gas transfer is required, a request information is first submitted to the service terminal 30, such as requesting to start the exhaust fan in the leachate collection tank to exhaust the gas in the leachate collection tank into the landfill tank, and then the service terminal 30 will evaluate the request after the safety evaluation, and then send the corresponding control instruction information of the exhaust fan.

[0078] Therefore, the gas flow control module 20 first receives the control instruction information fed back by the service terminal 30 through the information receiving unit 201, and then controls the corresponding exhaust fan or air suction fan to be started according to the instruction information to transfer the gas in the space.

[0079] If the request is to exhaust the gas in the leachate collection tank into the landfill tank for mixing, the gas mixing unit 202 will send the gas in the leachate collection tank into the landfill tank according to the received control instruction information.

[0080] If the request is to exhaust the gas in the leachate collection tank into the landfill tank for mixing, the gas mixing unit 202 will send the gas in the leachate collection tank into the landfill tank according to the received control instruction information.

[0081] In the application embodiment, the service terminal 30 corresponds to a data processing center and a central control platform, and the service terminal 30 is specifically configured to redefine the safety concentration threshold before controlling the gas flow according to the concentration detection result fed back by the gas concentration detection module 10, and generate a control instruction according to the safety concentration threshold, and send the control instruction to the gas flow control module 20.

[0082] Specifically, referring to Figure 4 , the service terminal 30 includes a data receiving module 31, a concentration threshold defining module 32, a control information generating module 33, and an information sending module 34.

[0083] The data receiving module 31 is configured to receive the concentration detection result fed back by the gas concentration detection module 10.

[0084] The concentration threshold defining module 32 is configured to calculate and obtain the safety concentration threshold before the gas flow according to the concentration detection result.

[0085] The control information generation module 33 is configured to generate gas flow transfer control instruction information according to the safety concentration threshold.

[0086] The information sending module 34 is configured to send the control instruction information to the gas flow transfer control module 20.

[0087] Firstly, the service terminal 30 receives the concentration detection result synchronized by the gas concentration detection module in real time through the data receiving module 31, and when the service terminal 30 receives a gas flow transfer request from the outside, the outside request can be understood as the request information sent by the relevant staff through the associated terminal platform or mobile terminal device. The service terminal 30 evaluates the gas concentration change after the gas flow transfer according to the request information, and then calculates and obtains the safety concentration threshold before the gas flow transfer through the concentration threshold definition module 32 according to the current concentration detection result.

[0088] Specifically, referring to Figure 5 , the concentration threshold definition module 32 includes a classification calculation unit 321, a concentration deviation calculation unit 322, and a concentration threshold adjustment unit 323.

[0089] The classification calculation unit 321 is configured to calculate the concentration of the mixed gas according to the type of the gas, which is denoted as the single-mixture concentration.

[0090] The influence coefficient calculation unit 322 is configured to calculate and obtain the concentration influence coefficient according to the single-mixture concentration and the concentration before mixing.

[0091] The concentration threshold adjustment unit 323 is configured to adjust the safety concentration threshold according to the concentration deviation.

[0092] Since the concentration detection result includes the type and corresponding concentration of the gas, the concentration of the mixed gas can be calculated according to the type of the gas first, which is denoted as the single-mixture concentration. For example, if the gas in the leachate collection pool is discharged into the garbage pool, the concentration of the mixed gas can be calculated according to the concentration of each type of gas in the current leachate collection pool and the garbage pool, and the concentration of each type of gas is denoted as the single-mixture concentration.

[0093] Then the influence coefficient calculation unit 322 calculates and obtains the concentration influence coefficient according to the single-mixture concentration and the concentration before mixing. The influence coefficient represents the degree of influence of the gas in the leachate collection pool on the concentration of the gas in the garbage pool after the gas flows into the garbage pool. Since the types, concentrations, and volumes of the gases in the leachate collection pool and the garbage pool are different, the concentration of a single gas may change greatly after mixing.

[0094] For example, the gas detection result of methane in the garbage pool before mixing is 8% LEL, while after mixing, the estimated gas detection result of methane is 8.3% LEL. Since the concentrations of various gases, the volume of the space in the garbage pool, and the exhaust volume of the exhaust fan, i.e., the volume of the gas exhausted per unit time, can be calculated, the concentration of each type of gas in the mixed gas after the gas in the leachate collection pool is exhausted into the garbage pool by the exhaust fan can be calculated, i.e., the monomer mixing concentration. Then, by comparing the concentration before mixing, the influence coefficient can be calculated. For example, the current methane concentration deviation is +0.3% LEL, which can be converted into the influence coefficient of the methane gas in the leachate collection pool on the concentration of the methane gas in the garbage pool as 0.3 / 8=0.375.

[0095] After obtaining the concentration influence coefficient, the safety concentration threshold can be re-adjusted by the concentration threshold adjustment unit 323 according to the concentration influence coefficient. Since the concentration of the gas in the garbage pool is always changing, it is necessary to adjust the safety threshold. For example, in the above example, the concentration influence coefficient of methane is 0.375, so the safety concentration threshold should be adjusted to 10% LEL*(1-0.375)=0.9625% LEL before the gas flow mixing.

[0096] Similarly, the new safety concentration threshold for each type of gas can be calculated. If the concentration of each gas in the garbage pool is within the new safety concentration threshold, the gas flow in the space can be allowed.

[0097] Similarly, after the gas in the leachate collection pool is exhausted into the garbage pool to form a mixed gas, the mixed gas is sent into the incinerator, which will also give the gas in the garbage pool a new safety concentration threshold. Since the gas in the incinerator is more complex and there is no concentration detection device, the concentration of flammable gas in the incinerator can only be evaluated based on historical data or actual processing experience, and then a relatively safe gas concentration is used as the timing for sending the mixed gas into the incinerator for incineration.

[0098] It is worth noting that the safety concentration threshold does not need to be adjusted every time. If the gas concentration detection result estimates that the gas in the leachate collection pool will not increase the concentration of the gas in the garbage pool after being exhausted into the garbage pool, then the safety concentration threshold does not need to be adjusted.

[0099] After the safety concentration threshold of the gas flow is obtained, the gas flow control instruction information can be generated by the control information generation module 33 according to the safety concentration threshold, that is, only when the concentrations of each gas in the current garbage pool are within the corresponding safety concentration threshold, the spatial flow of the gas can be allowed, and finally the control instruction information is sent to the gas flow control module 20 through the information sending module 34. The gas flow control module 20 starts the exhaust fan or the air suction fan according to the control instruction information to perform the spatial flow of the gas.

[0100] Because there are some malodorous gases such as ammonia and hydrogen sulfide in addition to flammable gas in the garbage pool and the leachate collection pool, corresponding deodorization treatment is also performed.

[0101] Therefore, in the embodiment of the present application, the system further comprises a deodorization module 40.

[0102] Specifically, the deodorization module 40 is used for deodorizing the leachate pool and the garbage pool by activated carbon adsorption. The activated carbon adsorption is developed by using the porosity of activated carbon and the principle of attraction. When the solid surface is in contact with the gas, the gas molecules can be attracted, concentrated and maintained on the solid surface. That is, when the waste gas is in contact with the large surface area of the porous activated carbon, the pollutants in the waste gas are adsorbed on the solid surface of the activated carbon, so as to separate from the gas mixture and achieve the purpose of purification.

[0103] In addition, by performing deodorization treatment, on the one hand, the influence of malodorous gas on the surrounding environment is reduced, and on the other hand, the gas is separated to some extent, which is more helpful for detecting flammable gas.

[0104] In addition, because flammable gas usually needs a certain ignition temperature to be able to explode, for example, the ignition temperature of methane is 650-750°C, and open flame, electric spark, smoking or even spark generated by impact and friction can be used as ignition adjustment.

[0105] Therefore, in order to further ensure the safety of the garbage power plant, the system further comprises a fire extinguishing module 50.

[0106] Specifically, the fire extinguishing module is used for real-time smoke detection of the garbage pool by machine vision. When the light is detected, an alarm prompt is sent, and the detection result is synchronized to the service terminal 30.

[0107] In the embodiment of the present application, the entire garbage power plant, especially the place or space where combustible gas is more, is monitored in real time, and images and videos are collected in the form of similar monitoring. A pre-trained target detection model based on video images is used for detection. When sparks, fireworks and other predetermined targets are detected, corresponding prompt information is generated on the service terminal 30, and the alarm device associated with the service terminal 30 will alarm and prompt, and control the fire monitor to aim at the ignition point, and start the electric valve and fire monitor pump to implement fire extinguishing.

[0108] The embodiment of the present application also provides an explosion-proof method for a garbage incineration power plant, referring to Figure 6 , comprising the following steps:

[0109] S100, real-time acquisition of gas concentration detection results in the current garbage pool and leachate collection pool.

[0110] S200, defining a safety concentration threshold according to the gas concentration detection results after receiving the gas flow request information.

[0111] S300, sending control instruction information to the gas flow control template 20 when the gas in the garbage pool reaches the corresponding safety concentration threshold.

[0112] In the embodiment of the present application, the gas concentration detection module 10 is first used to acquire the gas concentration detection results in the current garbage pool and leachate collection pool in real time. When the gas needs to be transferred, that is, the service terminal 30 receives the request information of the gas flow, the gas concentration after completing the cross-space flow will be evaluated to determine whether the concentration will reach the safety concentration threshold due to the change of the concentration. Therefore, the concentration of the mixed gas needs to be estimated after comprehensive evaluation, so as to redefine the safety concentration threshold.

[0113] Specifically, the safety concentration threshold is defined according to the gas concentration detection results, comprising the following steps:

[0114] S210, calculating the concentration of the mixed gas according to the gas concentration detection results, and recording it as the single mixed concentration.

[0115] S212, calculating and acquiring the concentration influence coefficient according to the single mixed solubility and the concentration before mixing.

[0116] S213, adjusting the safety concentration threshold according to the concentration influence coefficient.

[0117] Since the gas concentration detection result includes the type of gas and the corresponding concentration, the concentration of the mixed gas can be calculated according to the type of gas first, which is referred to as the single mixed concentration. For example, if the gas in the leachate collection tank is discharged into the garbage tank, the mixed gas concentration can be calculated according to the concentration of each type of gas in the current leachate collection tank and the garbage tank, and the concentration of each type of gas is recorded as the single mixed concentration.

[0118] Then, the concentration concentration influence coefficient is calculated and obtained according to the single mixed concentration and the concentration before mixing. The influence coefficient represents the influence degree of the gas in the leachate collection tank on the gas concentration in the garbage tank after the gas flows into the garbage tank. Then, the safety concentration threshold is adjusted again according to the concentration influence coefficient. That is, the spatial flow of the gas is allowed only when the concentration of each gas in the garbage tank reaches the safety concentration threshold. In this way, even if the spatial flow of the gas increases the concentration of the gas in the original garbage tank, the concentration will still be maintained within a safe concentration range.

[0119] Finally, after obtaining the current safety concentration threshold, the safety concentration threshold is used as a reference for determining whether the gas can flow across the space. That is, when the gas in the garbage tank reaches the corresponding safety concentration threshold, a control instruction information is sent to the gas flow control module 20. The gas flow control module 20 starts the exhaust fan or the air suction fan according to the control instruction information to perform the spatial flow of the gas.

[0120] The embodiments of the present application also provide a computer readable storage medium storing a computer program capable of being loaded by a processor and executing any of the above-mentioned explosion-proof methods of the garbage incineration power plant.

[0121] The embodiments of the specific implementation are preferred embodiments of the present application, but do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the principles of the present application should be covered within the protection scope of the present application.
