Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering, and specifically to an integrated sludge high-dry dewatering device capable of synchronously online detection of pore size and moisture content. Sludge dewatering technology is an indispensable part of the sewage treatment process, which aims to effectively remove moisture from sludge and increase the solid content of sludge, thereby reducing the difficulty of subsequent treatment and disposal. With the increasingly stringent environmental protection regulations and the enhancement of resource recycling awareness, the innovation and optimization of sludge dewatering technology and equipment are particularly important. Background Art

[0002] Sludge dewatering is an important technology in the environmental field. Its main purpose is to remove water from the sludge generated during sewage treatment, making the sludge denser and easier to handle and dispose of. Effective sludge dewatering can not only reduce the volume of sludge, reduce transportation and disposal costs, but also facilitate subsequent resource recovery. Therefore, improving sludge dewatering efficiency and reducing energy consumption are important directions for current technological development. This technology is also of great significance to environmental protection and social sustainable development.

[0003] The sludge dewatering technology in the prior art usually uses the filtration effect of a filter press to perform dewatering work, but the existing filter press has the following defects in actual use:

[0004] 1. During the in-situ synergistic dehydration of sludge, the existing technology is not equipped with a sample sampling device, and cannot detect the changes in the pore size and moisture content of the sludge in real time. This defect makes it impossible for operators to obtain information on changes in sludge characteristics in a timely manner, thus affecting the optimization of the dehydration effect;

[0005] 2. In the process of microwave and mechanical synergistic dehydration, the moisture content and porosity of the sludge cannot be observed in real time, resulting in a lack of necessary data guidance for the entire dehydration system. This lack of information affects the accuracy of the operation, thereby reducing the operating accuracy and dehydration efficiency of the equipment;

[0006] 3. The current microwave drying technology consumes a lot of energy. The main reason is that it is impossible to monitor the pore size and moisture content in real time, which leads to unreasonable energy distribution and inability to effectively reduce energy consumption. In addition, the utilization efficiency of thermal energy has not been fully utilized, which further affects the dehydration efficiency. Summary of the invention

[0007] The present invention aims to solve the problems that the bound water in the extracellular polymers of the current municipal sludge is difficult to discharge, and the pores are clogged during the filtration process, resulting in pore channels being blocked. In addition, the moisture content and the internal pore size cannot be detected in real time during the dehydration process, and the progress of the dehydration process cannot be accurately regulated. The purpose of the present invention is to provide an integrated sludge high-drying dehydration device that can synchronously detect the pore size and moisture content online, so as to solve the above-mentioned problems.

[0008] To achieve the above object, the present invention provides the following technical solutions:

During dehydration, the centralized control console controls the high-pressure mechanical dehydration device to filter press and dehydrate the sludge. The high-pressure mechanical dehydration device is provided with a sludge sampling device, which is electrically connected to the centralized control console, and the operation of the sludge sampling device is controlled by the centralized control console. The device also comprises an online moisture content detection device and an pore size detection device, which are both electrically connected to the centralized control console. After the high-pressure mechanical dehydration device completes the initial dehydration, the sludge sampling device samples the sludge after the initial dehydration, and sends the samples to the online moisture content detection device and the pore size detection device for detection, respectively. The detection results are sent to the centralized control console for processing and storage, and the centralized control console determines whether the sludge needs further dehydration based on the detection results.

[0010] Furthermore, it also includes a microwave drying device arranged in the high-pressure mechanical dehydration device. When the high-pressure mechanical dehydration device performs filter pressing and dehydration, the microwave drying device dehydrates the sludge synchronously.

[0012] Furthermore, the microwave power and frequency of the microwave generator can be adjusted by a microwave control module according to data feedback, thereby achieving precise control of drying energy consumption.

[0013] Furthermore, the filter plate is provided with a cable hole for connecting the microwave generator and the microwave control module by cable.

[0014] Furthermore, a mud sampling port is provided on the top of the filter plate, and a sludge sampling device can extend through the mud sampling port into between the filter plates for sampling.

[0015] Furthermore, a sealing bolt for sealing the mud intake port is threadedly connected at the mud intake port, and the sealing bolt can be taken out by rotating the sealing bolt to open the mud intake port.

[0016] Furthermore, the sludge sampling device is a cylindrical sampler that can be inserted between filter plates for sampling. The bottom of the cylindrical sampler is provided with two opposing clamps that can open or close the bottom opening of the cylindrical sampler. The cylindrical sampler is provided with a piston that can completely push out the sludge.

[0017] Furthermore, the cylindrical sampler is fixed to the movable end of a mechanical arm arranged on the high-pressure mechanical dehydration device, and the sampling and sample delivery of the cylindrical sampler are controlled by the mechanical arm.

[0018] The method for using the integrated sludge high-drying dehydration device capable of synchronously online detecting pore size and moisture content comprises the following steps:

[0019] Step 1: The sludge enters the device and is dehydrated by the high-pressure mechanical dehydration device and the microwave drying device at the same time;

[0020] Step 2: After the first dehydration, the sludge sampling device takes samples and sends them to the moisture content online detection device and the pore size detection device for detection;

[0021] Step 3: The test results are uniformly sent to the centralized control console for analysis and judgment. If the sludge dehydration test results meet the dehydration requirements, the dehydration is terminated. Otherwise, step 2 is repeated to perform dehydration until the test results meet the dehydration requirements.

The H protons absorb the radio frequency pulse energy and release it. The coil detects the energy release process, thereby obtaining the nuclear magnetic resonance signal; the relaxation time of sludge water molecules with different apertures is different, and the sludge aperture can be inferred by analyzing these signals.

The feedback control system in the centralized console is connected with the high-pressure mechanical dehydration device 1, the sludge automatic sampling device 3, the microwave drying device 2, the moisture content online detection device 4 and the pore size detection device 5 through the control line. The detected data information is used to judge whether the pore size is within the range of 1-10um and whether the moisture content is below 40%, and then the working equipment is feedback controlled online until the sludge dehydration and drying results meet the pore size range of 1-10um and the moisture content is below 40%.

After the first filter pressing and drying operations are completed, the sludge sampling device 3 quickly samples the sludge sample, and the moisture content and pore size are detected by the moisture content online detection device 4 and the pore size detection device 5. The data acquisition and processing system collects, stores and sends the detected data to the feedback control system to judge the sludge. Whether the pore size and moisture content need further filtration and re-drying, and the feedback control system and microwave control module in the centralized control console 6 of the device are used to adjust the size of mechanical filtration and the power and frequency of microwave drying respectively, so that the dehydration process is more accurate, the dehydration efficiency is better, and energy is fully utilized to reduce energy consumption; when the monitored pore size is within the range of 1-10um and the moisture content is below 40%, the dehydration effect is achieved and the dehydration process is completed; when the situation does not meet the above standards, the next step of mechanical filtration and microwave drying is performed to reduce the sludge moisture content and pore size again, and then the above detection and judgment operations are repeated. If the standards are met, the dehydration is completed, otherwise the mechanical filtration and microwave drying are continued until the set standards are reached and the work is completed.
