Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically a containerized sludge dewatering auxiliary system. Background Technology

[0002] In industrial production, pharmaceutical wastewater treatment, agricultural and livestock solid waste disposal, and municipal sewage treatment plants, sludge with high water content is generated in all these production activities. This high moisture content makes the sludge highly susceptible to putrefaction and environmental pollution, necessitating dewatering systems to reduce its volume and facilitate transportation and subsequent disposal. Traditional dewatering systems typically consist of multiple independent modules, such as a feeding system, dewatering unit, dosing system, and control system. Each module requires on-site installation and connection of pipes and electrical circuits, resulting in large equipment footprints, long installation periods, high transportation costs, and difficulty in adapting to mobile or temporary operation needs.

[0003] In existing technologies, some dewatering systems attempt to adopt modular designs to simplify the installation process. However, the auxiliary equipment (such as pump sets, dosing devices, and electrical control cabinets) are still scattered, resulting in complex pipeline layouts and inconvenient maintenance. In addition, traditional dewatering systems are poorly adaptable to harsh environments (such as mining, river dredging, and disaster areas) or situations requiring frequent relocation, making it difficult to meet the requirements of rapid deployment and flexible operation.

[0004] Chinese patent CN201821364180.1 discloses a containerized sludge dewatering system, including a dosing metering pump, a sludge feed screw pump, an integrated dosing device, a screw press sludge dewatering machine, an integrated electrical control cabinet, and a container. The equipment has a high degree of integration, but it does not consider the discharge of filtrate from the screw press. Integrating the dewatering machine and auxiliary equipment into a single container makes the space cramped, maintenance difficult, and requires additional design of a cooling system due to the large number of motors.

[0005] Chinese patent CN202322996829.9 discloses a skid-mounted sludge dewatering system. This system includes a conditioning module, a filter press module, a scraper conveyor, and a sludge storage module arranged sequentially. The conditioning module comprises a skid-mounted chassis and a conditioning tank, a homogenizing tank, and a sludge transfer pump mounted on the chassis. The filter press module uses a high-pressure diaphragm filter press. Although the conditioning module is integrated in a skid-mounted configuration, the entire dewatering system remains inconvenient for transportation and cannot meet the requirements for flexible operation.

[0006] Therefore, there is an urgent need for a highly integrated dehydration equipment solution that integrates auxiliary equipment into a container, enabling the overall transportation of the equipment, rapid deployment, energy efficiency, and improved environmental adaptability, thereby overcoming the shortcomings of existing technologies.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] This embodiment provides a containerized sludge dewatering auxiliary system, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this system is used in conjunction with a belt dewatering machine.

[0046] The dosing system 1 is used for dosing chemicals; the treatment process is as follows: the dosing system is used for dosing chemicals, the sludge is concentrated and flocculated in the sludge thickening system 3 after dosing chemicals and then settles to the bottom. The sludge is then transported to the belt dewatering machine for dewatering through the sludge discharge system 5. The air compressor 2 provides air to the belt dewatering machine. The flushing system 4 transports the supernatant from the sludge thickening system 3 to the belt dewatering machine for filter cloth flushing. The electrical cabinet 6 controls the belt dewatering machine and the equipment in the auxiliary system.

[0047] Specifically, the dosing system 1 includes a high-efficiency mixer 1-1, a high-efficiency mixer inlet 1-1-1, a high-efficiency mixer outlet 1-1-2, a dosing port 1-1-3, a PAM preparation device 1-2, a filtrate PAM dosing pump 1-3, and a PAM dosing pump 1-4. Two high-efficiency mixers 1-1 are provided, one installed on the filtrate pipe and the other on the sludge pipe.

The PAM dosing pump 1-4 is a diaphragm metering pump, and the PAM dosage is 3~5 kg / tDS. The PAM preparation device 1-2 is placed on one side of container 7. The function of the high-efficiency mixer 1-1 is to fully mix sludge and chemicals through stirring, so that the sludge forms flocs, which is conducive to subsequent sedimentation.

[0048] Sludge thickening system 3 adopts a vertical flow sedimentation tank with a maximum influent flow rate of 40 m³ / h. 3 / h, hydraulic load is 12m 3 / (hm 2After sedimentation, the sludge is discharged through a sludge discharge system. The moisture content of the settled sludge is approximately 93%. A sludge thickening system 3 is located on the other side of container 7. This system is a high-efficiency sedimentation tank 3-1, above which is a clear water tank 3-2. The clear water tank 3-2 has an overflow outlet, which discharges into container 7 through a pipe.

[0049] The sludge discharge system 5 is placed in the middle of the container 7; the sludge discharge system 5 is introduced into the bottom of the high-efficiency sedimentation tank 3-1 through a pipe. The high-efficiency sedimentation tank 3-1 adopts a conical bottom. After the sludge settles in the conical bottom, it is discharged through the pipe suction port by the sludge discharge system 5. The sludge discharge system 5 adopts a sludge screw pump.

[0050] Air compressor 2 is placed above sludge removal system 5 and is fixed by an angle steel gantry frame. Air compressor 2 provides air for the tensioning and alignment systems of the belt dewatering machine. Air compressor 2 has a gas pressure of 0.8 MPa and a discharge volume of 0.32 m³ / min.

[0051] The rinsing system 4 includes a rinsing water pump 4-1 and a rinsing water filter 4-2. The bottom of the clear water tank 3-2 is connected to the rinsing water pump 4-1 and the rinsing water filter 4-2 sequentially via pipes. The suction end of the rinsing water pump 4-1 draws water from the clear water tank 3-2. To ensure the rinsing water quality meets the standard (SS≤50mg / L), the rinsing water is pumped by the rinsing water pump 4-1 and filtered by the rinsing water filter 4-2. After filtration, the water is finally piped to the sludge dewatering equipment for rinsing the filter cloth in the equipment.

[0052] Container 7 includes a filtrate inlet 7-1, a sludge inlet 7-2, a PAM preparation device inlet 7-3, a PAM vent 7-4, a sludge discharge pump outlet 7-5, a flushing water pump outlet 7-6, and a clear water tank overflow outlet 7-7.

[0053] The filtrate inlet 7-1 and the sludge inlet 7-2 are connected to the top side of the high-efficiency sedimentation tank 3-1 via pipelines, which are used to transport sludge and belt filter press filtrate to the high-efficiency sedimentation tank 3-1.

[0054] The PAM preparation device inlet 7-3 is connected to the PAM preparation device 1-2 via a pipe for supplying water to dissolve the reagent.

[0055] PAM vent 7-4 is connected to the bottom of PAM preparation device 1-2 via a pipe for discharging reagents from inside PAM preparation device 1-2.

[0056] The sludge discharge port 7-5 of the sludge discharge pump is connected to the sludge discharge system 5, which is used to transport the sludge from the bottom of the high-efficiency sedimentation tank 3-1 out of the auxiliary system.

[0057] The flushing water outlet 7-6 is connected to the flushing water filter 4-2. After filtration, the flushing water is discharged from the auxiliary system through the flushing water outlet 7-6 and is used for rinsing the filter cloth of the belt dewatering machine.

[0058] The overflow port 7-7 of the clear water tank is connected to the clear water tank 3-2. If there is too much supernatant in the high-efficiency sedimentation tank 3-1, it will be discharged from the auxiliary system through the overflow port 7-7 of the clear water tank.

[0059] The specific processing procedure is as follows: The PAM preparation device 1-2 is located on one side of container 7. The PAM preparation device 1-2 has a preparation speed of 2000 L / h. The reagents are respectively delivered to the dosing port 1-1-3 of the high-efficiency mixer through the filtrate PAM dosing pump 1-3 and the PAM dosing pump 1-4. PAM, sludge, and filtrate are mixed and flocculated in the high-efficiency mixer 1-1-1. The flocculated sludge flows into the high-efficiency sedimentation tank 3-1 for sedimentation and concentration. The sludge after sludge-water separation settles at the bottom, and the supernatant enters the clear water tank 3-2. A portion of the supernatant is drawn by the flushing water pump 4-1, filtered through the flushing water filter 4-2, and discharged from the auxiliary system through the flushing water outlet 7-6. The flushing water is transported through pipelines to the belt dewatering machine for filter cloth washing to ensure the normal operation of the belt dewatering machine. The other part of the excess supernatant is discharged from the auxiliary system through the overflow port 7-7 of the clear water tank.

[0060] Subsequently, the sludge at the bottom of the high-efficiency sedimentation tank 3-1 is concentrated and has a water content of 90%~94%. It is then pumped out through the sludge discharge system 5 via pipeline. The sludge discharge system 5 uses a sludge screw pump and finally discharges the sludge from the auxiliary system through the sludge discharge outlet 7-5. The concentrated sludge is then transported through pipeline to a belt dewatering machine for further dewatering treatment.

[0061] Finally, air compressor 2 is connected to the pneumatic valve box of the belt dewatering machine through an air pipe to provide air supply to the tensioning system and the belt dewatering system of the belt dewatering machine, ensuring the normal operation of the belt dewatering machine.

[0062] In summary, this design can highly integrate the auxiliary equipment in the sludge dewatering system, making the equipment easy to transport and transfer, and easy to install. It can treat the wastewater generated by the sludge dewatering system without putting unnecessary load on the front-end water treatment system, thus achieving closed-loop treatment.
