Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to a desulfurization wastewater pipeline dredging system. Background Art

[0002] At present, limestone-gypsum wet desulfurization technology is a widely used desulfurization process in industrial production. Its efficient desulfurization capacity is widely recognized. However, its shortcomings are also very obvious. In addition to the complex process system, it is found in the wastewater treatment process that due to the sludge in the discharged wastewater, the wastewater system often has problems such as excessive particles, sludge deposition leading to blockage of the conveying system pipeline, and filter cloth damage. The existing wastewater treatment system requires manual pipeline clearing or pipeline replacement, which is inefficient and cannot completely discharge the crystal blocks deposited inside the pipeline, resulting in poor clearing effect and frequent pipeline blockage. After two years of operation, the pipeline is aged and the diameter becomes thinner. Once blocked, it is very easy for the previous desulfurization process to fail to operate normally. The various connections of the pipeline are not easy to disassemble during maintenance, and there is no flushing pipeline. Even if the equipment is shut down, it cannot be flushed, which brings many difficulties to maintenance.

[0003] In addition, due to the long desulfurization wastewater pipeline, the pipeline crossing corridors and roads, deep burial and frequent elevation, the pipeline flow will become smaller after a period of use. The effect of multiple flushing with flushing water is not ideal. Less sediment falls off the pipeline, and manual dredging is difficult. Some pipelines cannot even be dredged, which brings inconvenience to the wastewater discharge work and affects the stable operation of the desulfurization system.

[0004] A patent document with application number CN218901043U discloses a wastewater treatment system, including a wastewater pipe, a filtered water pipe and a filter; the filter includes a housing and a filter element disposed in the housing and separating the housing into a first cavity and a second cavity, the housing is provided with a water inlet interface and a sewage discharge interface connected to the first cavity and a drainage interface connected to the second cavity, the wastewater pipe is connected to the water inlet interface, the filtered water pipe is connected to the drainage interface, and the wastewater pipe is provided with a flushing water interface and a first valve located upstream of the flushing water interface. The above-mentioned comparative document has the phenomenon that the pipe will still be blocked after long-term operation.

[0005] In view of this, the inventor conducted in-depth research on how to provide a desulfurization wastewater pipeline dredging system that is not prone to pipeline clogging and is easy to operate, which resulted in the present case. Utility Model Content

[0006] In order to overcome the problem in the prior art that desulfurization wastewater is blocked inside the pipeline and does not affect the normal desulfurization process, the utility model provides a desulfurization wastewater pipeline dredging system, including an air intake device, which is arranged on the wastewater pipeline; the air intake device includes a compressed air pipeline arranged on the wastewater pipeline;

[0008] The wastewater pipeline is set up in a specific pipeline area to solve the problem of desulfurization wastewater being blocked inside the pipeline. An air intake device and a pipeline vibration device are arranged on the wastewater pipeline. The dirt deposited in the pipeline is cleaned through the air intake device, and the pipeline is vibrated by the vibration device to stir the water in the underground pipeline and then use the fluidity of the wastewater itself to bring out the sediment and debris, thereby reducing the labor intensity of the workers. The wastewater pipeline is cleaned thoroughly as a whole, and the wastewater is discharged smoothly, which can ensure the normal operation of the desulfurization system.
