Description

Technical Field

[0001] The present invention relates to the technical field of hot drink preparation devices, and more particularly to a self-regulating method, device and system for an anaerobic reactor. Background Art

[0002] Anaerobic reactors are specialized reactors used in anaerobic treatment technology. The anaerobic reaction process is essentially a series of complex biochemical reactions, in which substrates, various intermediate products, final products, and various microbial populations interact to form a complex micro-ecosystem. These microorganisms form a symbiotic or symtrophic relationship through nutrient substrates and metabolic products. Therefore, as a micro-ecosystem that supports microbial growth and reproduction, the steady growth of various microorganisms and the efficient and smooth flow of substances and energy are essential conditions for maintaining the system's continued stability.

[0003] In order to maintain the efficient and stable operation of the above system, a lot of time, manpower and material resources are required. At the same time, the process of non-methanogenic bacteria degrading organic matter during the operation of the anaerobic reactor can produce a large amount of VFA and CO2, and gradually the problem of organic wastewater acidification will occur, which restricts the treatment energy efficiency of the anaerobic reactor. Summary of the Invention

[0004] In order to solve the problem that the debugging and operation of anaerobic reactor equipment in actual use consumes a lot of time, manpower and material resources, but the treatment efficiency of the anaerobic reactor cannot be effectively improved, this application proposes an anaerobic reactor self-regulation method on the one hand, which uses the data self-regulation principle to automatically adjust the water inlet and dosage of the anaerobic reactor to achieve efficient and stable operation of the anaerobic reactor. To achieve the above method, this application proposes an anaerobic reactor self-regulation device on the other hand, and finally proposes an anaerobic reactor self-regulation system. The specific scheme is as follows:

[0005] A self-regulating method for an anaerobic reactor, comprising:

[0006] Establish a theoretical relationship model between each detection factor data and each regulatory action;

[0007] Set and store correction algorithms for various adjustment actions;

[0008] Collect and implement adjustment actions based on the data of various detection factors, and generate the theoretical fluctuation range of each detection factor data according to the existing theoretical relationship model;

[0009] Continuously collecting various detection factor data and comparing them with the theoretical fluctuation range, generating deviation values and storing them in association with the corresponding detection factor data and adjustment actions;

[0010] Correct the adjustment action when the deviation value exceeds the set range, and re-associate and store it with the data of various detection factors to form a new theoretical relationship model;

[0011] Based on the above theoretical relationship model and the collected detection factor data, the revised adjustment action is implemented until the fluctuation range of the detection factor data is within the set range.

[0012] Through the above technical solution, the water inlet and the dosage can be automatically optimized based on the different detection factor data in the anaerobic reactor, so that the reaction of the entire anaerobic reactor is maintained in a high-efficiency and stable range.

[0013] Furthermore, the establishment of a theoretical relationship model between each detection factor data and each adjustment action includes:

[0014] Calculate and control the water inflow of the anaerobic reactor based on the detected influent CODcr and the sludge load previously input;

[0015] Determine the C:N:P ratio of sewage based on the detected CODcr, TN, and TP, and calculate and control the dosage of supplementary TN and TP;

[0016] Calculate and control the dosage of alkaline agent based on the detected VFA, alkalinity, methane production and CODcr removal rate;

[0017] According to the detected temperature of the anaerobic reactor, the steam regulating valve or the electric heating device is controlled to adjust the temperature of the anaerobic reactor.

[0018] Furthermore, the method further comprises:

[0019] Setting up multiple different dosing areas and / or water inlet areas in the anaerobic reactor;

[0020] The adjustment action also includes changing the drug addition area and / or the water inlet area based on the detection factor data.

[0021] Through the above technical solution, multiple dosing areas or water inlet areas are set in the anaerobic reactor. According to the changes in the detection factor data after water inflow or dosing in different water inlet areas or dosing areas, the best dosing area and water inlet area can be found, thereby obtaining the best adjustment action, which helps to improve the reaction efficiency of the entire anaerobic reactor.

[0022] Furthermore, the method further comprises:

[0023] Delineate different temporary reaction areas in the anaerobic reactor;

[0024] Different theoretical relationship models representing the correlation between detection factor data and adjustment actions are set in each temporary reaction area;

[0025] Calculate the fluctuation range of the detection factors in each temporary reaction area and obtain the optimal theoretical relationship model based on the calculation results;

[0026] Based on the above optimal theoretical relationship model and the detection factor data collected from each temporary reaction area, corresponding adjustment actions are performed on the entire reaction area.

[0027] Through the above technical solution, the entire anaerobic reactor is divided into different reaction areas, each of which corresponds to a different theoretical relationship model. Based on the above settings, the optimal theoretical relationship model can be found in a short time, thereby improving the reaction efficiency of the entire anaerobic reactor in a short time.

[0028] Furthermore, the different temporary reaction areas are defined in the anaerobic reactor, including:

[0029] Different temporary reaction areas are formed by arranging water inlet ports, liquid addition ports and guide plates; or

[0030] The reaction zones are separated by partitions in the anaerobic reactor.

[0031] Based on the above anaerobic reactor self-regulation method, the present application also proposes an anaerobic reactor self-regulation device, comprising:

[0032] Control components;

[0033] A water inlet assembly includes a water inlet pipe and a water inlet pump. The water inlet pipe is provided with a water inlet selection valve at one end near the anaerobic reactor.

[0034] A dosing assembly includes multiple drug storage tanks, a dosing pump, and a dosing pipe. One end of the dosing pipe is connected to the drug storage tank. A dosing selection valve is provided near one end of the anaerobic reactor. The dosing selection valve is connected to multiple sub-dosing pipes, which extend into different positions in the anaerobic reactor to form multiple dosing ports.

[0035] A detection component, comprising a plurality of detection elements for detecting and outputting detection factor data in the anaerobic reactor, wherein the plurality of detection elements are respectively arranged at different positions in the anaerobic reactor and are signal-connected to the control component;

[0036] The control component receives the detection factor data output by the detection component and controls the actions of the water inlet component and the drug adding component.

[0037] Through the above technical solution, the water inlet and dosage of the anaerobic reactor are controlled based on the detection results of the detection component, which helps to improve the reaction efficiency and stability of the entire anaerobic reactor and makes the control reliable and convenient.

[0038] Furthermore, the self-regulating device further comprises:

[0039] The reaction area separation component is configured as at least one flexible partition and its driving member provided in the anaerobic reactor. The flexible partition is controlled by the driving member and moves along a set track to separate the anaerobic reactor into multiple reaction areas. The driving member is control-connected to the control component, receives control instructions from the control component and outputs driving actions.

[0040] Through the above technical solution, the entire anaerobic reactor can be quickly divided into multiple different temporary reaction areas, making it easier to find and confirm the optimal theoretical relationship model at the same time, and then apply it to the entire anaerobic reactor, thereby improving the working efficiency and stability of the entire anaerobic reactor in a short period of time.

[0041] Furthermore, the detection assembly includes a plurality of sampling tubes, which form a plurality of sampling ports at different positions of the anaerobic reactor. The plurality of sampling tubes are collected into a sampling main pipe and then connected to the anaerobic reactor.

DETAILED DESCRIPTION

[0056] The present invention will be further described in detail below with reference to the embodiments and figures, but the embodiments of the present invention are not limited thereto.

[0057] A self-regulating method for an anaerobic reactor 600, such as Figure 1 As shown, it mainly includes the following steps:

[0058] S100, establishing a theoretical relationship model between each detection factor data and each adjustment action;

[0059] S200, setting and storing correction algorithms for various adjustment actions;

[0060] S300, collecting and implementing adjustment actions based on various detection factor data, and generating theoretical fluctuation ranges of various detection factor data according to existing theoretical relationship models;

[0061] S400, continuously collecting various detection factor data and comparing them with the theoretical fluctuation range, generating a deviation value and storing it in association with the corresponding detection factor data and adjustment action;

[0062] S500, correcting the adjustment action in which the deviation value exceeds the set range, and re-associating and storing it with the data of each detection factor to form a new theoretical relationship model;

[0063] S600: Implement the revised adjustment action based on the theoretical relationship model and the collected detection factor data until the fluctuation range of the detection factor data is within the set range.

[0064] In this application, the above-mentioned detection factor data refers to the various detection factors in the anaerobic reactor 600, such as CODcr, TN, TP and other data of sewage, and the adjustment action refers to the action performed to change the above-mentioned detection factors, such as changing the water intake, adding alkaline agents, etc.

[0065] In the above step S100, the correlation between the detection factor data and each adjustment action includes:

[0066] A, based on the detected CODcr of the influent of the anaerobic reactor 600 and the sludge load previously input, calculate and control the influent volume of the anaerobic reactor 600. The influent volume refers to the amount of sewage entering the anaerobic reactor 600 through the inlet pipe 101.

[0067] B. According to the detected CODcr, TN and TP, determine the C:N:P ratio of the sewage, calculate and control the dosage of supplementary TN and TP.

[0068] C. Calculate and control the dosage of alkaline agents, such as baking soda, soda ash, NaOH, etc., based on the detected VFA, alkalinity, methane production and CODcr removal rate.

[0069] D. According to the detected temperature of the anaerobic reactor 600 , the steam regulating valve or the electric heating device is controlled to adjust the temperature of the anaerobic reactor 600 .

[0070] In the above-mentioned step S200, the correction algorithm for setting and storing various adjustment actions includes: when the fluctuation range of the actual detection factor data (since the anaerobic reaction is a dynamic process, each data fluctuates within a certain range) differs too much from the theoretical fluctuation range generated by the theoretical relationship model, it indicates that there are other influencing factors in the entire reaction process. In order to offset the interference of the above-mentioned influencing factors, the adjustment action needs to be adjusted, such as making fine adjustments to the water inlet within the set range in the theoretical relationship model.

[0071] Since anaerobic reaction is actually an interaction between substrates, various intermediate products, final products, and various groups of microorganisms, the interior of the anaerobic reactor 600 is a complex micro-ecosystem. Changes in the location of drug addition or water inlet will also lead to changes in the reaction efficiency of the anaerobic reactor 600. Therefore, in order to obtain the best reaction efficiency, the method of the present application also includes:

[0072] S101, setting a plurality of different dosing areas and / or water inlet areas in the anaerobic reactor 600;

[0073] S301, the adjustment action also includes changing the drug addition area and / or the water inlet area based on the detection factor data.

[0074] Based on the above technical solution, multiple dosing areas or water inlet areas are set in the anaerobic reactor 600. According to the changes in the detection factor data after water inflow or dosing in different water inlet areas or dosing areas, the best dosing area and water inlet area can be found, thereby obtaining the best adjustment action, which helps to improve the reaction efficiency of the entire anaerobic reactor 600.

[0075] In practice, since the anaerobic reactor 600 is usually a whole, the detection factor data or adjustment action data corresponding to each position in the anaerobic reactor 600 are consistent. In order to obtain the optimal theoretical relationship data, it is necessary to continuously adjust the water inlet and the dosage, which is time-consuming. Therefore, the method of the present application also includes:

[0076] D100, defining different temporary reaction areas in the anaerobic reactor 600;

[0077] D200, a theoretical relationship model representing the correlation between detection factor data and adjustment actions corresponding to different settings in each temporary reaction area;

[0078] D300, calculate the fluctuation range of the detection factor in each temporary reaction area and obtain the optimal theoretical relationship model based on the calculation results;

[0079] D400, based on the above optimal theoretical relationship model and the detection factor data collected from each current temporary reaction area, implements corresponding adjustment actions on the entire reaction area.

[0080] The above technical solution divides the entire anaerobic reactor 600 into different reaction areas, each of which corresponds to a different theoretical relationship model. Based on the above setting, the optimal theoretical relationship model can be found in a short time, thereby improving the reaction efficiency of the entire anaerobic reactor 600 in a short time.

[0081] Furthermore, the above step D100, defining different temporary reaction areas in the anaerobic reactor 600, includes: forming different temporary reaction areas by arranging the water inlet pipe 101, the liquid addition pipe port and the guide plate; or

[0082] The reaction areas are separated by partitions provided in the anaerobic reactor 600 , so that the anaerobic reactor 600 has a plurality of relatively independent reaction spaces.

[0083] Based on the above-mentioned self-regulating method of the anaerobic reactor 600, the present application also proposes a self-regulating device for the anaerobic reactor 600, such as Figure 2 As shown, it includes: a control component, a water inlet component 100, a dosing component 200 and a detection component.

[0084] The control component includes a PLC control module and a data storage module connected thereto. The data storage module is used to store the detection factor data, the corresponding theoretical relationship model, and other related data. The control component receives the detection factor data output by the detection component and controls the operation of the water inlet component 100 and the dosing component 200.

[0085] The water inlet assembly 100 includes an inlet pipe 101 and an inlet pump 102. The inlet pipe 101 is connected to an external sewage collection tank. A water inlet selector valve 103 is provided at one end of the inlet pipe near the anaerobic reactor 600. The inlet selector valve 103 is connected to multiple inlet sub-pipes 104, which extend into different locations within the anaerobic reactor 600 to form multiple water outlets. In practice, a guide plate may be provided at the water inlet to control the direction of water flow at the water inlet. The inlet selector valve 103 is an electrically operated selector valve that is controllably connected to the control assembly and controls the water output of each outlet in response to control commands from the control assembly.

[0086] The dosing component 200 includes a plurality of drug storage tanks 203, a dosing pump 202 and a dosing pipe 201. The above-mentioned drug storage tank 203 is used to contain the agent to be added to the anaerobic reactor 600. The above-mentioned agent is preferably a liquid mixed agent, such as NaOH solution. One end of the dosing pipe 201 is connected to the drug storage tank 203, and the other end is provided with a dosing selection valve near the anaerobic reactor 600. Similar to the water inlet pipe 101, the dosing selection valve is connected to a plurality of sub-dosing pipes 204, and the plurality of sub-dosing pipes 204 extend into different positions in the anaerobic reactor 600, respectively, to form a plurality of dosing ports. The dosing selection valve is connected to the control component and controls the dosing amount of each dosing pipe 201 in response to the control instruction of the control component;

[0087] The detection component includes a plurality of detection elements 301 for detecting and outputting detection factor data in the anaerobic reactor 600. The plurality of detection elements 301 are respectively disposed at different positions of the anaerobic reactor 600 and are signal-connected to the control component.

[0088] In the embodiment of this application, Figure 2 As shown, the detection assembly includes multiple sampling tubes 403, which form multiple sampling ports at different locations in the anaerobic reactor 600. The multiple sampling tubes 403 are collected in a sampling main pipe 404 and then connected to the anaerobic reactor 600. The sampling main pipe 404 is provided with an electric valve 405, a circulation pump 406, and multiple detection elements 301. In practice, the electric valve 405 is also configured as a selection valve. The electric valve 405 and the sampling pump are controlled and connected to the control assembly to select different sampling ports to obtain detection factor data at different locations in the anaerobic reactor 600. During the sampling process, the sewage entering the sampling tubes 403 from the sampling ports circulates back to the anaerobic reactor 600 through the sampling main pipe 404. Each detection element 301 is provided at the sampling main pipe 404, which is located outside the anaerobic reactor 600 and can quickly and effectively detect various detection factors in the sewage without affecting the normal operation of the entire anaerobic reactor 600.

[0089] like Figure 2 As shown, the sampling ports are sequentially positioned along the height of the anaerobic reactor 600, and the sludge concentration in the tank is monitored using the aforementioned method. In one specific embodiment, assuming that at a certain upward flow rate X, the vertical distribution of the sludge concentration in the tank (from top to bottom) is 0 g / L, 0.2 g / L, 0.5 g / L, 0.8 g / L, 1 g / L, 1.5 g / L, and 2 g / L, the upward flow rate is then increased by X + 0.2 m / h. After stabilization for 4 hours, the sludge concentration is tested until the sludge concentration at the outlet exceeds 0.1 g / L, at which point the upward flow rate is stopped.

[0090] like Figure 2As shown, in an embodiment of the present application, the self-regulating device further includes a reaction area separation component 400. The reaction area separation component 400 is configured as at least one flexible partition 401 and its driving member 402 provided in the anaerobic reactor 600. The flexible partition 401 can be made of a plastic material or cloth that does not react with sewage. Similar to an automatically retractable and lifting curtain structure, the flexible partition 401 is controlled by the driving member 402 to move to separate the anaerobic reactor 600 to form multiple reaction areas. In order to fix the movement trajectory of the flexible partition 401, a track is provided on the inner side wall of the anaerobic reactor 600, and the two side edges of the flexible partition 401 are slidably connected to the track, and an elastic recovery member is provided between the bottom edge of the flexible partition 401 and the bottom of the anaerobic reaction tank. When the flexible partition 401 is in the retracted state, the elastic recovery member stores elastic potential energy.

[0091] The driver 402 is an external servo motor connected to the control assembly and transmits the drive force to the interior of the anaerobic reactor via a transmission rod. The driver 402 receives control commands from the control assembly and outputs a driving action, causing the flexible partition 401 to retract or release, thereby dividing the interior of the anaerobic reactor 600 into multiple distinct reaction zones. This technical solution allows the entire anaerobic reactor 600 to be quickly divided into multiple temporary reaction zones, facilitating the simultaneous identification and confirmation of the optimal theoretical relationship model, which can then be applied to the entire anaerobic reactor 600, quickly improving the operating efficiency and stability of the entire anaerobic reactor 600.

[0092] Optimally, in this application, the self-regulating device further comprises a temperature detection component and a temperature regulating component. The temperature detection component comprises a plurality of temperature sensors disposed at different positions in the anaerobic reactor 600, detecting and outputting temperature detection signals representing the temperature of each reaction area of the anaerobic reactor 600.

[0093] The temperature control assembly includes multiple heat pipes or electric heating tubes 500 connected to an external heat source. The heat pipes or electric heating tubes 500 receive control commands from the control assembly and heat the different reaction zones of the anaerobic reactor 600. Since the heating device and its operating principle of the anaerobic reactor 600 are well known in the prior art, they will not be described in detail here. In this embodiment, to prevent temperature interference between the different reaction zones, the flexible partition 401 is made of an insulating material or an insulating interlayer is added to the plastic partition, such as an insulating felt. This allows for precise temperature control of each reaction zone in the anaerobic reactor 600.

[0094] Based on the above-mentioned anaerobic reactor 600 self-regulating device, the present application also proposes an anaerobic reactor 600 self-regulating system, such as Figure 2As shown, it includes an anaerobic reactor 600 body and the anaerobic reactor 600 self-regulating device as described above, which is arranged in conjunction with the anaerobic reactor 600 body.

[0095] Similar to the prior art, the anaerobic reactor 600 includes a reaction tank body and a water inlet pipe 101 disposed at the bottom of the reaction tank body. The water inlet pipe 101 utilizes the aforementioned multiple water inlet sub-pipes 104, which are distributed at different locations on the bottom of the anaerobic tank body. A circulating water pipe and a circulating pump 406 are disposed on the outside of the tank body. In certain embodiments, the circulating water pipe of the anaerobic reactor 600 can be implemented using the aforementioned sampling pipe 403 and sampling main pipe 404, thereby sampling and testing the wastewater while ensuring its circulation. A three-phase separator 602 and an outlet weir 603 are located at the top of the reaction tank body to separate and discharge clean water and biogas. The reaction tank body is also provided with a sludge outlet 601.

[0096] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
