Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization wastewater resource utilization devices, in particular to an industrial flue gas magnesium method desulfurization wastewater resource utilization device. Background Art

[0002] my country is a large country in energy production and consumption. Coal accounts for a large proportion in my country's energy structure system. Among them, the amount of coal burned in coal-fired power plants accounts for more than 50% of coal consumption. Coal-fired power plants produce a large amount of flue gas containing sulfur dioxide due to coal burning. Flue gas sulfur dioxide is an important precursor pollutant for environmental problems such as acid rain and haze. In the process of desulfurization of flue gas, a large amount of sulfur-containing wastewater will be generated. The discharge of sulfur-containing wastewater will cause a waste of resources. The sulfur inside the wastewater can be extracted and separated for reuse. In the process of utilizing the wastewater, the wastewater needs to be filtered and the impurities inside the wastewater are pre-filtered. However, the impurities in the wastewater in the filtering equipment in the prior art are easy to block the filtering equipment during the filtering process of the wastewater, affecting the filtering efficiency, and the filtered wastewater still contains relatively fine particles and impurities, resulting in an increase in the amount of dosing in the later stage, affecting the processing cost. Therefore, it is necessary to improve the prior art. Utility Model Content

[0005] Preferably, the lower end of the output shaft of the motor is fixedly connected to the connecting shaft of the gear, and the gear is meshed with the gear ring, so that the motor can drive the gear to rotate.

[0006] Preferably, one end of the spring is fixedly connected to the guide frame, and the other end of the spring is fixedly connected to the movable frame, and the spring can support the movable frame by elastic force.

[0007] Preferably, a brush is fixedly connected to one side of the support frame close to the conical net barrel, and the brush is in contact with the conical net barrel, so that the brush can scrub the holes of the conical net barrel.

[0008] Preferably, a stabilizing ring is installed in the middle of the inner wall of the processing box through a bearing, and the stabilizing ring is slidably connected to the filter barrel. The stabilizing ring can support the rotating filter barrel.

[0009] Preferably, the supernatant discharge mechanism includes a drain pipe, the lower end of the processing box is fixedly connected to the drain pipe, the drain pipe is fixedly connected to a support bar, the support bar is slidably connected to a slide rod, the upper end of the slide rod is fixedly connected to a float, the outer side of the slide rod is fixedly connected to a sealing cover, the sealing cover is slidably connected to the drain pipe, and the float can drive the sealing cover to move by buoyancy.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model adds a gear ring, a filter barrel and a brush inside the treatment box. In the process of treating wastewater, the gear ring can drive the filter barrel to rotate. The centrifugal force generated by the rotation of the filter barrel will throw away the impurities adsorbed on the outside of the conical net barrel. At the same time, the conical net barrel can be cleaned by the brush, thereby avoiding clogging of the conical net barrel and ensuring filtering efficiency.

[0012] 2. The utility model adds structures such as a drain pipe, a sealing cover and a float ball inside the treatment box. When discharge needs to be carried out through the drain pipe during use, the liquid level surface at the bottom of the treatment box needs to drive the sealing cover under the float ball to separate from the drain pipe before discharge can be carried out. In the process of rising liquid level surface, fine particles in the wastewater can be precipitated, thereby effectively reducing the particle content of the wastewater and reducing the amount of reagents used in the later stage.

[0022] The specific implementation process of the utility model is as follows: when in use, waste water is discharged into the interior of the filter barrel 5 through the water inlet pipe 4, and the waste water is filtered through the conical net barrel 6 inside the filter barrel 5. During the filtering process, the motor 9 is started, and the motor 9 drives the gear 8 to rotate, and the gear 8 drives the filter barrel 5 to rotate through the gear ring 7. During the rotation of the filter barrel 5, the conical net barrel 6 can drive the conical net barrel 6 to rotate. During the rotation of the conical net barrel 6, the centrifugal force generated can be used to throw away the debris from the conical net barrel 6.

[0023] After filtration, the wastewater enters the bottom of the treatment box 1. When the water level cannot contact the float 24, the water level gradually rises.
