Description

Technical Field

[0001] The invention relates to a desulfurization wastewater treatment device, in particular to a desulfurization wastewater treatment device and a use method thereof, belonging to the technical field of sewage treatment equipment. Background Art

[0002] Desulfurization wastewater is the result of limestone-gypsum wet desulfurization of coal-fired boiler flue gas. In order to prevent the concentration of soluble chloride ions, heavy metals and fine dust particles in the slurry from being too high during the desulfurization process and maintain the balance of materials in the desulfurization device, the wastewater discharged contains many complex impurities. Direct discharge without treatment will seriously threaten the safety of environmental water bodies. At present, the main treatment technology for desulfurization wastewater is the three-unit box process, which was introduced from abroad more than 20 years ago.

[0003] The existing patent (Announcement No.: CN208632140U) discloses a desulfurization wastewater treatment device, which relates to the technical field of sewage treatment equipment. It includes a casing, a water inlet is opened on one side of the casing, the casing is a cavity structure, a partition is welded on the inner wall of the casing, a filter is welded on one side of the partition, a base is fixed on one side of the inner wall of the casing by nuts and bolts, a waterproof motor box is fixed on one side of the base by screws, a servo motor is installed inside the waterproof motor box by screws, the output end of the servo motor is connected to a stirring rod through a coupling, stirring blades are fixed on both sides of the stirring rod by bolts, and a rotating rod is provided on the outside of the stirring rod. Through the arrangement of the filter screen, the swing rod, the brush head, the rocker and other structures, while the wastewater is being treated inside, the brush head can shake left and right to brush the filter screen at the bottom to prevent the filter screen from being blocked by impurities, effectively solving the problem of easy internal blockage in common desulfurization wastewater treatment. The present invention has a simple and practical structure and is suitable for popularization and use. In the process of implementing the scheme, the inventor found that the following problems in the prior art have not been well solved: 1. The device is provided with a mechanism for removing impurities from the filter screen. However, in the process of using the brush head to remove impurities, impurities at the corners of the filter screen are difficult to clean, and the distance from the filter screen is difficult to adjust. Impurities embedded in the filter screen and some smaller impurities are difficult to brush out and remove. Long-term filtration can easily cause a large number of impurities to be embedded in the filter screen, causing the filter screen to be blocked and difficult to clean; 2. When treating the sewage after precipitation, no evaporation and crystallization are performed, and the harmful substances contained in the sewage cannot be effectively removed, which can easily lead to excessive emissions, and the water vapor generated by evaporation is difficult to be fully utilized, and the water vapor cannot be used for power generation, which cannot effectively save electricity and easily cause energy waste; 3. When treating the precipitated sludge, it is necessary to manually add dehydration agents to the extracted sludge slurry, and the dosage of the medicine cannot be effectively controlled, which can easily cause insufficient reaction or waste of agents. The agent and the sludge slurry are difficult to mix evenly, which can easily affect the dehydration effect, and the dehydrated sludge cannot be dried, which is difficult to transport.

[0004] In addition, the brush roller in the existing patent technology is only simply rotated and reached, and its height and position cannot be adjusted, and impurities in different corners or at different heights cannot be removed. Summary of the invention

[0019] A method for using a desulfurization wastewater treatment device, the method comprising the following steps:

[0020] The first step is to perform preliminary filtration on the desulfurization wastewater through a coarse filter. When a lot of impurities appear on the coarse filter, start the two linear modules and the two first motors, rotate the brush roller and move the brush roller by adjusting the hole grooves, and quickly clean the impurities at various positions on the coarse filter. Then, collect the cleaned impurities through a trash can.

[0021] The second step is, when encountering some smaller impurities stuck in the mesh of the coarse filter, start the electric push rod and adjust the height of the brush roller through the adjustment holes on both sides of the filter box until the impurities stuck on the coarse filter can be cleaned out, then stop adjusting. This can effectively remove small and medium-sized impurities stuck in the filter and avoid filter blockage.

[0022] In the third step, the neutralized desulfurization wastewater is pumped into the evaporation box through a water pump, and two electric heating copper tubes are started to heat and evaporate the wastewater. The wastewater in the evaporation box is evaporated and crystallized, and the water vapor enters the placement box through the exhaust hood and the connecting pipe. The high-speed flowing water vapor rotates the turbofan arranged on the outer wall of the second rotating shaft, and then rotates the second rotating shaft, and then rotates the generator connected to one end of the second rotating shaft, and the mechanical energy is converted into electrical energy through the generator, and then the electrical energy is stored in the battery.

[0023] The fourth step is to discharge the water vapor into the condenser through the steam delivery pipe for condensation and liquefaction, and then input the condensed clean water into the clean water tank, and then test the clean water. The qualified clean water is discharged through the drain valve and reused. It can effectively remove harmful substances in sewage, avoid excessive emissions, make full use of water vapor for power generation, and effectively save electricity.

[0024] In the fifth step, the desulfurized wastewater after neutralization is filled with flocculant through the flocculant filling pipe in the sedimentation box to precipitate the wastewater. After the precipitated wastewater is pumped out, the sludge slurry is precipitated in the sludge sedimentation box, pumped out by the sludge suction machine, and discharged into the sludge treatment box through the sludge conveying pipe. The liquid level of the sludge slurry discharged is detected by the liquid level sensor, and the data is transmitted to the single-chip microcomputer. Through the processing and analysis of the single-chip microcomputer, it is determined that the dosage of the dehydration agent needs to be added. Through the control of the single-chip microcomputer, the first micro motor is started to extract the agent in the sludge dehydration agent placement box, and the extracted dosage is controlled by the second solenoid valve and the flow sensor, and injected into the sludge treatment box through the first infusion tube. After starting the first motor, the rotating blades are rotated by the first rotating shaft to stir and mix the sludge slurry and the agent. After sufficient reaction, the precipitated wastewater is pumped out, and then the fan is started to transmit hot air into the sludge treatment box through the electric heating cylinder to dry the sludge into blocks for easy transportation and utilization.

After the precipitated wastewater is extracted, the sludge slurry is precipitated in the sludge sedimentation box 35, extracted by the sludge suction machine 33, and discharged into the sludge treatment box 4 through the sludge conveying pipe 31. The liquid level of the discharged sludge slurry is detected by the liquid level sensor 59, and the data is transmitted to the single-chip microcomputer 49.
