Description

Technical Field

[0001] The present invention relates to a system and method for treating engineering waste mud, and in particular to a multi-dimensional coordinated system and method for treating engineering waste mud, and belongs to the technical field of waste mud treatment. Background Art

[0002] During the construction of bored piles, shield tunneling, underground continuous walls, and oil and gas drilling, a large amount of waste mud is inevitably generated. These engineering waste muds have the characteristics of high water content, high viscosity, fine solid particles, and high pollutant content, which significantly increase the difficulty of engineering waste mud treatment. Improper treatment of waste mud will pose a serious threat to environmental safety, specifically in the form of damage to water sources, soil and vegetation, affecting the normal operation of municipal facilities, such as sewer blockage, damage to sewage treatment facilities, corrosion of public facilities, and increased municipal maintenance costs. In addition, it will pose a threat to water ecological security and affect the safety of urban domestic water.

[0003] Traditional methods of treating waste mud, including natural drying, sedimentation in sedimentation tanks, and mechanical dehydration, have many limitations. These methods are inefficient, time-consuming, and require a large amount of land resources. The treated mud still contains a high amount of water, making it difficult to meet the requirements of environmental protection and resource recycling.

[0004] The natural drying method is extremely inefficient and greatly affected by weather conditions. It is almost impossible to carry out on rainy days or cold seasons. It requires a large area of ​​drying space, which is difficult to implement in urban areas with tight land resources. Dust pollution may be generated during the drying process, affecting the surrounding air quality. The final product still contains a high moisture content, which makes it difficult to cope with the large amount of waste mud generated by large-scale projects.

[0005] The sedimentation process of the sedimentation tank sedimentation method is slow and cannot meet the needs of rapid processing. It also requires the construction of a large sedimentation tank, which takes up a large amount of space. For sludge with high viscosity and fine particles, relying solely on gravity sedimentation is not effective, and the sludge after sedimentation still needs further dehydration and treatment.

[0006] Mechanical dehydration is easily affected by the properties of mud. For high-viscosity mud, it is difficult to achieve the ideal dehydration effect by relying solely on mechanical filter pressing, and fine particles can easily clog the filter cloth, reducing the dehydration efficiency.

[0007] Therefore, there is an urgent need to develop a new technology to achieve rapid, efficient and thorough treatment of engineering waste mud. Summary of the invention

This synergistic effect not only speeds up the treatment process, but also ensures the continuity and efficiency of the treatment process, significantly improving the overall performance of engineering waste slurry treatment.

[0056] The design of the thermal consolidation box 12 makes full use of the three physical effects of vacuuming, heating and pressurizing, which effectively promotes the discharge of moisture in the engineering waste slurry and accelerates the consolidation process of the waste slurry. At the same time, through the built-in pressure and temperature sensor 13, real-time monitoring and control of the thermal consolidation process are realized, ensuring the stability and reliability of the treatment process and improving the quality and efficiency of engineering waste slurry treatment.

[0057] The embodiment of the present invention further discloses a multi-dimensional collaborative engineering waste mud treatment method using the multi-dimensional collaborative engineering waste mud treatment system, comprising the following steps:

[0058] Pretreatment and filtration: inject the engineering waste mud into the waste mud box 1, use the filter plate 2 to preliminarily filter the engineering waste mud to remove larger particles, open the first conveying device 3 at the bottom of the waste mud box 1, and convey the filtered engineering waste mud to the flocculation cylinder 6;

[0059] Flocculation treatment: add an appropriate amount of flocculant to the engineering waste mud in the flocculation cylinder 6 to promote the aggregation of fine particles in the engineering waste mud, start the stirring device 7 to evenly stir the engineering waste mud in the flocculation cylinder 6 to ensure that the flocculant and the engineering waste mud are fully mixed. After the stirring is completed, let the engineering waste mud stand for a period of time to allow flocculation and precipitation;

[0060] Transportation and monitoring of engineering waste mud after flocculation: Open the second conveying device 8 at the bottom of the flocculation cylinder 6 to transport the engineering waste mud after flocculation and precipitation to the thermal consolidation box 12, and monitor the temperature and pressure state of the engineering waste mud in real time through multiple pressure and temperature sensors 13 set at different heights and different positions of the thermal consolidation box 12;

[0061] Preparation for thermal consolidation: When the engineering waste mud reaches the required height in the thermal consolidation box 12, close the second conveying device 8 at the bottom of the flocculation cylinder 6 to stop the conveying of the engineering waste mud, lay a sand cushion layer 15 on the top of the engineering waste mud, insert the drainage main plate 1402 and the drainage sub-plate 1403, and lay the pressure plate 18 flat on the sand cushion layer 15;

[0062] Thermal consolidation and dehydration: Start the heating motor 16 and the vacuum device 11 to heat and drain the engineering waste mud in the thermal consolidation box 12, and place a pressure block 19 on the pressure plate 18 to apply appropriate pressure to the engineering waste mud to promote the discharge of water in the engineering waste mud, so that the engineering waste mud can be dehydrated in the thermal consolidation box 12 and finally form a stable mud block.

[0063] In this method, each processing link can be carried out independently with high modularity and flexibility. While the hot consolidation box 12 is dehydrating and consolidating the waste slurry, the filtration and flocculation links can be operated in parallel to process other batches of waste slurry, thereby greatly improving the processing capacity of the entire system, reducing waiting time, and making the processing of engineering waste slurry more efficient and economical.

[0064] In order to further improve the control efficiency and control accuracy of the thermal consolidation step, the multi-dimensional collaborative engineering waste mud treatment method also introduces intelligent control into the thermal consolidation control process. Specifically, the thermal consolidation control method includes the following steps:

[0065] The pressure and temperature sensor 13 is used to collect the temperature T, pressure P and water content W data of the engineering waste mud in real time to establish the mud dehydration rate model Where f is the function of the machine learning algorithm, which is obtained by training the machine learning algorithm based on historical data;

[0066] Design an intelligent control system based on fuzzy PID control, the control target is to maximize the dehydration rate The controlled variables include heating power H, suction intensity V and pressure F of the pressure plate 18;

[0067] Control is performed through the control system. According to the real-time collected T, P, W data, the PID parameters are determined through fuzzy reasoning, and the optimal H, V, F control quantities are calculated. The mathematical expression is expressed as Among them, arg max represents the parameter combination that makes the objective function take the maximum value;

[0068] The control system continuously monitors the actual dehydration effect. If there is a deviation from the expected effect, the model parameters are automatically adjusted. The adjustment formula is: Among them, θ is the model parameter, η is the learning rate, and E is the prediction error;

[0069] The termination condition is set as the moisture content W is lower than the threshold and the continuous time change rate is less than the preset value. When the conditions are met, the thermal consolidation process is automatically terminated.

[0070] According to the state of the engineering waste mud, the heating power, the suction intensity and the pressure of the pressure plate 18 are dynamically adjusted to optimize the dehydration process. In the initial stage, higher temperature and lower pressure are conducive to reducing the adhesion between water molecules and accelerating water evaporation, while in the later stage, gradually increasing the pressure helps to overcome the capillary effect and promote the discharge of deep water. This dynamic adjustment method enables the entire system to maintain the maximum dehydration rate as much as possible, thereby significantly shortening the treatment cycle of engineering waste mud. In addition, by real-time monitoring of mud temperature and water content, accurate calculation of required heat, and ensuring that the right energy input is provided at each stage, unnecessary heat loss can be reduced and energy efficiency can be improved.

[0071] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.

A multi-dimensional collaborative engineering waste mud treatment method using a multi-dimensional collaborative engineering waste mud treatment system as claimed in any one of claims 1 to 7, characterized in that: The method comprises the following steps: Pretreatment and filtration: inject the engineering waste slurry into the waste slurry box (1), use the filter plate (2) to preliminarily filter the engineering waste slurry to remove larger particles, open the first conveying device (3) at the bottom of the waste slurry box (1), and convey the filtered engineering waste slurry to the flocculation cylinder (6); Flocculation treatment: adding an appropriate amount of flocculant to the engineering waste mud in the flocculation drum (6) to promote the aggregation of fine particles in the engineering waste mud, starting the stirring device (7) to evenly stir the engineering waste mud in the flocculation drum (6) to ensure that the flocculant and the engineering waste mud are fully mixed. After the stirring is completed, the engineering waste mud is allowed to stand for a period of time to allow flocculation and sedimentation; Transportation and monitoring of engineering waste mud after flocculation: opening the second conveying device (8) at the bottom of the flocculation cylinder (6) to transport the engineering waste mud after flocculation and sedimentation to the thermal consolidation box (12), and monitoring the temperature and pressure state of the engineering waste mud in real time through multiple pressure and temperature sensors (13) arranged at different heights and different positions of the thermal consolidation box (12); Preparation for hot consolidation: When the engineering waste slurry reaches the required height in the hot consolidation box (12), the second conveying device (8) at the bottom of the flocculation cylinder (6) is closed to stop the conveying of the engineering waste slurry, a sand cushion layer (15) is laid on the top of the engineering waste slurry, a drainage main plate (1402) and a drainage sub-plate (1403) are inserted, and a pressure plate (18) is placed flat on the sand cushion layer (15); Thermal consolidation and dehydration: The heating motor (16) and the exhaust device (11) are started to heat and exhaust the engineering waste mud in the thermal consolidation box (12). A pressure block (19) is placed on the pressure plate (18) to apply appropriate pressure to the engineering waste mud to promote the discharge of water in the engineering waste mud, so that the engineering waste mud is dehydrated in the thermal consolidation box (12) and finally forms a stable mud block.
