Description

Technical Field

[0001] The present invention relates to the technical field of hazardous waste treatment, and more specifically, to a hazardous waste pre-buried treatment system and a control method thereof. Background Art

[0002] my country's industrialization process is accelerating. Although this has promoted my country's economic growth, it has also produced a lot of hazardous wastes during industrial development, which has made the environmental pollution problem more serious. Therefore, in industrial production, the purification and treatment of hazardous wastes is essential. Nowadays, the concept of hazardous wastes has exceeded the scope of solid hazardous wastes commonly referred to. There are also many waste liquids that will pollute biological resources, water resources, land resources and the atmospheric environment, and even cause serious harm. The purification and treatment of hazardous wastes in the existing technology is relatively single, focusing on the purification and disposal of solid hazardous wastes, and rarely involving the comprehensive purification and treatment of solid and liquid hazardous wastes. Therefore, there is an urgent need for a comprehensive purification and treatment system for solid and liquid hazardous wastes.

[0003] For example, the patent number is CN201910159155.2, and the patent name is a rigid landfill system for hazardous waste and a hazardous waste transfer system. It adopts the landfill method. Although this method does not have a particularly large risk in the short term, in the long run, the landfill material will be highly corrosive, which will affect the life of the landfill structure and cause environmental pollution over time;

[0004] As for other traditional treatment systems, some are through chemical reactions, and some are through microbial decomposition, but the traditional structure cannot carry out effective and uniform reaction and decomposition, and the traditional reaction method basically enters from a single side, with poor uniformity. Therefore, in order to ensure the acceleration of reaction and decomposition, it is necessary to form a structure that can form uniform stirring to assist the reaction and decomposition. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a hazardous waste pre-buried treatment system and a control method thereof with good reaction effect, strong practicality and high uniformity.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a pre-buried treatment system for hazardous waste, comprising a pre-buried unit, the pre-buried unit being arranged in a pit, the pre-buried unit comprising at least one pre-buried pool, the pre-buried pool being open at the top and being surrounded by a pre-buried pool bottom wall and a pre-buried pool side wall extending upward from the pre-buried pool bottom wall;

[0007] A sealing unit, wherein the sealing unit is adapted to seal the upper opening of the pre-buried pool when the pre-buried pool is filled with hazardous waste;

[0008] The treatment unit is connected to the pre-buried pool and delivers a chemical reaction treatment agent or a microbial group solution to the pre-buried pool;

[0009] The import and export units export hazardous wastes; and the treated wastes are first filtered and then precipitated to initially separate the solids and liquids, and then the solids and liquids are tested for pH and alkalinity, and then discharged after they meet the emission standards;

[0010] It also includes an internal transport mechanism arranged in the pre-buried pool, which includes a plurality of reaction chambers arranged in the pre-buried pool and an internal conveyor arranged in the reaction chamber, the internal conveyor is connected to the conveying pipeline of the processing unit, and the internal conveyor is configured to transport the chemical reaction treatment agent and the microbial group solution into the reaction chamber.

[0011] The present invention is further configured as follows: the internal conveyor includes a rotating cylinder arranged in the reaction chamber, a plurality of external through holes arranged on the rotating cylinder, a first solenoid valve arranged on the external through holes, a rotating motor rotatably connected to the rotating cylinder, an inner pipe arranged in the rotating cylinder and connected to the conveying pipe, an inner through hole arranged on the inner pipe, and a second solenoid valve arranged on the inner through hole, and the inner through hole and the external through hole are connected to each other.

[0012] The present invention is further configured as follows: the inner conveyor also includes a thickness detector for the thickness of the chemical reaction treatment agent and the microbial group solution surface attached output arranged on the inner pipe and a flow detector arranged in the inner pipe, and the aperture of the inner through hole is larger than the aperture of the outer through hole.

[0013] The present invention is further configured as follows: the bottom wall of the embedded pool includes a reinforced concrete bottom wall and a first anti-seepage layer covering the reinforced concrete bottom wall; the side walls of the embedded pool include a reinforced concrete side wall and a second anti-seepage layer covering the reinforced concrete side wall.

[0014] A control method applicable to the above-mentioned hazardous waste pre-buried treatment system also includes a controller, the controller includes a monitoring unit, which is used to monitor the thickness of the attached output in real time and the flow rate in the inner pipe in real time; a comparison unit, which is used to set the optimal thickness value and the optimal flow rate value, and compare with the electrical signal transmitted by the monitoring unit; a timing unit, which is used to time a certain thickness stage and a certain flow stage; a pH value detection unit, which is electrically connected to the pH value detector and detects the current pH value in the reaction chamber; and a control unit, which is used to control the delivery flow of the delivery pipeline and the rotation speed of the rotating motor, including the following steps: S1, putting hazardous waste into each reaction chamber, and setting the optimal thickness value on the rotating cylinder to H, setting the warning film thickness to H0, setting the optimal flow rate in the inner pipe to L, and setting the warning flow rate in the inner pipe to L0 through the controller;

[0015] S2. The thickness and flow rate are monitored in real time by the monitoring unit, and the monitored thickness value is Ht, the flow rate value is Lt, and the pH value detector detects the pH value in the reaction formula after t time, and the detection value is W. When the pH value is 7, it is in the best state;

[0016] S3. In the first time period, according to the content of hazardous waste in each reaction chamber, a matching and quantitative chemical reaction treatment agent or microbial solution is output and transported through the internal pipeline, and the reaction time is 30 minutes;

[0017] S4. During the first time period, when the reaction solution is transported, the output volume needs to be strictly controlled, and the reaction solution in the inner pipe is first transferred to the rotating cylinder, and then the reaction solution in the cylinder is thrown out and enters the reaction chamber through the centrifugal force generated by the rotation of the rotating cylinder. The thickness detector monitors the thickness of the solution in the rotating cylinder in real time and records it as H1. When H1 is less than H0, the reaction solution needs to be continuously transported through the inner cylinder, otherwise, the reaction solution continues to be output through the rotating cylinder;

[0018] S5. In the second time period, when the flow detector detects that the flow value is less than L0, it is judged that the reaction solution delivery is nearing the end. After the inner pipeline output is completed, at this time, the thickness sensor on the rotating cylinder will monitor the current thickness value H2 in real time. When the current thickness H2 is less than H0, the control unit controls to reduce the rotation speed of the rotating cylinder and closes the outer through hole through the first solenoid valve until the reaction is completed;

[0019] S6. In the third time period, the pH detector performs detection after the reaction is completed. If the detected pH value is between 7±0.5, the neutralization is completed. If the pH value exceeds the above range, the reaction solution needs to be continuously output. The content of the reaction solution to be output as a whole is first controlled through the inner pipeline. After the inner pipeline is transported to the rotating cylinder, the rotating cylinder is rotated by the rotating motor. After reaching the preset speed, the first solenoid valve opens the outer through hole and outputs the reaction solution in the rotating cylinder.

[0020] S7, after the reaction is completed, the pH detector performs detection after the reaction is completed. If the detected pH value is between 7±0.5, the neutralization is completed. If the pH value exceeds the above range, the operation returns to step S6;

[0021] S8. After reaching the emission standard, the reactants in the reaction chamber are discharged.

[0022] By adopting the above technical scheme, the beneficial effects are as follows: 1. The present invention forms an area for centralized treatment of hazardous wastes by setting up a pre-buried unit and burying the pre-buried unit in a pit, and also includes a sealing unit, a processing unit and an import and export unit, wherein the sealing unit is to ensure the generation of harmful gases and form a relatively closed reaction environment, and the processing unit is set up to treat different hazardous wastes by chemical reactions or microbial decomposition. At the same time, the present application also adds an internal conveying mechanism, because the internal conveying mechanism includes a plurality of reaction chambers and an internal conveyor arranged in the reaction chamber, which can rotate and stir the hazardous waste in the reaction chamber through the internal conveyor, and output the treatment solution in real time in a stable manner, and stir the reactants in the reaction chamber while reacting, thereby improving the overall reaction rate and greatly improving the practicality;

[0023] 2. In the present invention, the inner conveyor is configured to include a rotating cylinder disposed in the reaction chamber, an inner pipe disposed in the rotating cylinder and connected to the conveying pipe, and the inner conveyor is configured to include the cooperation between the rotating cylinder and the inner pipe, the inner pipe is used as the main output, and through a plurality of outer through holes disposed on the rotating cylinder, a first solenoid valve disposed on the outer through hole, a rotating motor rotatably connected to the rotating cylinder, an inner through hole disposed on the inner pipe, and a second solenoid valve disposed on the inner through hole, the inner through hole and the outer through hole are connected to each other, the reactant in the inner pipe can be transported to the reaction chamber, and the dosage of the reactant can be accurately controlled, and the reactants in the reaction chamber can be fully stirred by the rotation of the rotating cylinder, so that a sufficient reaction effect can be formed, the reaction rate can be increased, the practicality is greatly improved, and the structure is relatively simple;

[0024] 3. The inner conveyor also includes a thickness detector for measuring the thickness of the chemical reaction treatment agent and the microbial group solution attached to the surface of the inner pipe and a flow detector arranged in the inner pipe. The aperture of the inner through hole is larger than the aperture of the outer through hole. In order to ensure that the chemical reaction treatment agent and the microbial group solution can be transported stably and continuously, the amount of the reactant is accurately controlled to improve the decomposition or neutralization of hazardous wastes, thereby achieving a good treatment effect, strong practicality and simple structure;

[0025] 4. In the control method of the present invention, the main output pipeline is formed by controlling the inner delivery pipeline, and the optimal flow value in the pipeline is detected, as well as the optimal thickness on the rotating cylinder is detected in real time, because the rotating cylinder is used to throw out the reactants by centrifugal force while stirring, and then react with the hazardous waste in the reaction chamber, and the pH value can be detected in real time to continue to adjust the amount of reactants in real time, and the quantitative output of the reactants can be achieved through flow detection and detection of the optimal thickness on the rotating cylinder, thereby improving the overall practicality.

After the inner pipe 41 is transported to the rotating cylinder 62, the rotating cylinder 62 is rotated under the drive of the rotating motor 63. After reaching the preset speed, the first solenoid valve 621 opens the outer through hole 620 and outputs the reaction solution in the rotating cylinder 62.
