Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for a desulfurization tower that can be recycled. Background Technology

[0002] Wastewater treatment devices for desulfurization towers are specialized environmental protection equipment used to treat high-salt, high-pollutant wastewater discharged from industrial desulfurization systems such as coal-fired power plants and steel plants, enabling it to meet discharge standards or be reused. Desulfurization towers are environmental protection equipment used in industrial production to remove sulfur dioxide and other sulfides from flue gas, with the core function of reducing environmental pollution such as acid rain.

[0003] When workers need to treat wastewater, they input the wastewater into the treatment device for processing. However, existing treatment devices often have short processing times, resulting in suboptimal treatment effects and subsequent failures to meet standards in later treatment steps. Utility Model Content

[0004] The purpose of this invention is to solve the problem that wastewater in the subsequent treatment steps of the existing technology fails to meet the standards, and to propose a wastewater treatment device for desulfurization towers that can be recycled.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wastewater treatment device for desulfurization towers that can be recycled, comprising a flocculation tank, an agitator disposed on the upper surface of the flocculation tank, the agitator blades being located at the bottom of the flocculation tank, a reflux device disposed on the inner wall of the flocculation tank, the reflux device comprising a receiving pipe fixedly connected to the inner wall of the flocculation tank, the receiving pipe being located on one side of the agitator, a groove being formed on one side of the receiving pipe, a suction pipe being slidably connected inside the receiving pipe, a flexible hose being fixedly connected to the top end of the suction pipe, and the top end of the flexible hose being flush with the surface of the groove. A sliding connection is used. A water pump is fixedly connected to one side of the flocculation tank. The bottom end of the hose is fixedly connected to the surface of the water pump. A three-way valve is provided on one side of the flocculation tank. A drain pipe is fixedly connected between the three-way valve and the water pump. A conveying pipe is fixedly connected to the surface of the three-way valve. A return pipe is fixedly connected between the three-way valve and the flocculation tank. An adjustment component is provided at the top of the receiving pipe. The adjustment component includes a first motor and a conveying rod. The first motor is fixedly connected to the top of the receiving pipe. The first motor is located above the flocculation tank. The first motor can cooperate with the receiving pipe to support the first motor.

[0006] Preferably, the drive end of the first motor is fixedly connected to a transmission rod, the transmission rod is rotatably connected to the inside of the receiving tube, and the transmission rod is threadedly connected to the inside of the suction pipe. The transmission rod can cooperate with the suction pipe and the first motor to achieve the purpose of adjusting the suction pipe to extract wastewater from a specified water layer.

[0007] Preferably, the flocculation tank is provided with a sealing device, which includes a receiving trough. The receiving trough is located inside the flocculation tank and is situated on one side of the return pipe. The receiving trough can cooperate with the flocculation tank to guide the sealing plate.

[0008] Preferably, the inside of the receiving trough is slidably connected to a sealing plate, which is located on one side of the return pipe. The sealing plate can cooperate with the receiving trough to block wastewater.

[0009] Preferably, the surface of the sealing plate is provided with drainage holes, which are aligned with the grooves at the bottom of the flocculation tank. The drainage holes can cooperate with the sealing plate to guide the wastewater backflow.

[0010] Preferably, a second motor is fixedly connected inside the flocculation tank, and an adjusting rod is fixedly connected to the drive end of the second motor. The adjusting rod is threadedly connected to the inside of the sealing plate and rotatably connected to the inside of the flocculation tank. The second motor can cooperate with the flocculation tank, the adjusting rod, and the sealing plate to adjust the sliding of the sealing plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a reflux device, when the worker needs to circulate wastewater, the worker starts the first motor, which drives the conveyor rod. The conveyor rod pushes the suction pipe, which slides downward to the target water layer. The water pump is then started, generating negative pressure. The suction pipe draws in wastewater, which enters the hose from the suction pipe. The hose guides the wastewater into the water pump, which then guides it into the drain pipe. The drain pipe guides the wastewater into the three-way valve, which then guides it into the delivery pipe. When the worker detects that the wastewater treatment effect is not up to standard, the worker activates the three-way valve, which guides the wastewater into the reflux pipe. The worker also activates the sealing device, which opens the slot at the bottom of the flocculation tank, allowing the wastewater to reflux back into the tank. Simultaneously, the wastewater pushes up the settled impurities, and the agitator re-flocculates the wastewater. By setting up the reflux device, the worker can effectively and conveniently circulate the wastewater, avoiding unsatisfactory treatment effects and reducing the likelihood of substandard wastewater in subsequent treatment steps.

[0012] In this invention, by setting up a sealing device, when the operator needs to prevent wastewater from entering the idle return pipe, the second motor is started. The second motor drives the adjusting rod, which pushes the thread inside the sealing plate. The sealing plate is guided and slides by the receiving groove. The drainage holes on the surface of the sealing plate are misaligned with the holes and grooves at the bottom of the flocculation tank. The sealing plate closes the holes and grooves at the bottom of the flocculation tank. By setting up the sealing device, wastewater can be effectively prevented from entering the idle return pipe, avoiding sediment from clogging the return pipe, which is conducive to the normal use of the return device.

[0018] Specifically, the first motor 38 is fixedly connected to the top of the receiving pipe 31. The first motor 38 is located above the flocculation tank 1. The first motor 38 can cooperate with the receiving pipe 31 to support the first motor 38.

The receiving trough 41 can cooperate with the flocculation tank 1 to guide the sealing plate 43.

[0022] Specifically, the storage slot 41 has a sliding connection to a sealing plate 43, which is located on one side of the return pipe 35.

The sealing plate 43 closes the hole groove at the bottom of the flocculation tank 1. By setting up the sealing device 4, it is possible to effectively prevent wastewater from entering the idle reflux pipe 35, avoiding sediment from clogging the reflux pipe 35, thus facilitating the normal use of the reflux device 3.
