Description

Technical Field

[0001] The utility model relates to a purification device, in particular to a vertical water purification device. Background Art

[0002] The turbid circulating water is the water that comes out of the blast furnace slag flushing pump house, passes through the blast furnace slag flushing, returns to the slag flushing water tank along the slag flushing ditch for precipitation, and then enters the suction well of the slag flushing pump house for recycling. The turbid circulating water usually contains a lot of impurities and sludge precipitates, and a flocculant needs to be added to precipitate and filter the impurities and sludge in the turbid circulating water. The sludge filtered out after adding a catalyst to the turbid circulating water contains alum flower particles. The alum flower particles are an adsorbent, which adsorbs the suspended substances in the water and the precipitates generated by the reaction to play a role in crystallization, promotes the gradual increase of the sediment, accelerates the sedimentation and separation. Therefore, adding a part of the sludge filtered after the reaction before purifying the turbid circulating water makes the turbid circulating water easier to crystallize, the sediment increases and the sedimentation is faster, increasing the purification rate of the turbid circulating water.

[0003] The existing turbid circulating water purification devices have complex structures, large floor areas, and general treatment effects. Summary of the Utility Model

[0004] Object of the Invention: The object of the utility model is to overcome the deficiencies in the prior art and provide an internal structure of a vertical water purification device with a small floor area, a simple structure, and a good treatment effect.

[0005] Technical Solution: To solve the above technical problems, the internal structure of the vertical water purification device described in the utility model includes a vertical cylinder body, which is a flat-bottomed structure. A cleaning pipe is arranged in the upper part of the vertical cylinder body, a sloping plate is arranged below the cleaning pipe, a micro-vortex flocculation reaction zone is arranged below the sloping plate, a negative pressure hydraulic ejector is arranged below the micro-vortex flocculation reaction zone, the opening of the negative pressure hydraulic ejector faces upward, and it is connected to the middle pipe in the micro-vortex flocculation reaction zone. A sludge discharge area I is arranged between the micro-vortex flocculation reaction zone and the negative pressure hydraulic ejector, a sludge discharge area II is arranged at the bottom of the vertical cylinder body, and a negative pressure sludge return pipe is arranged at the lower part of the middle pipe, and the lower end of the negative pressure sludge return pipe is arranged in the sludge discharge area II.

[0006] Furthermore, an inner manhole I is arranged on the micro-vortex flocculation reaction zone, and an inner manhole II is arranged on the sludge discharge area II.

[0007] Furthermore, the micro-vortex flocculation reaction zone includes a middle pipe, the upper end of the middle pipe is connected to a micro-vortex flocculation propeller, and a hydraulic self-rotating micro-vortex flocculation device is arranged outside the middle pipe.

[0008] Furthermore, a sludge discharge pipe I is arranged on the sludge discharge area I, and an electric valve I is arranged on the sludge discharge pipe I.

[0009] Further, a second sludge discharge pipe is provided on the second sludge discharge area, and an electric valve II is provided on the second sludge discharge pipe.

The vertical cylinder is adopted, which occupies a small area. The cleaning area, inclined plate area, micro-vortex flocculation reaction zone, and negative pressure hydraulic ejector are arranged from top to bottom in the vertical cylinder. The structure is simple and reasonable, and the treatment effect is good.

[0013] The negative pressure hydraulic ejector is designed by using the Venturi principle, so that the water flow velocity is instantaneously reduced from 4.72 m / s to 1.18 m / s, and a vacuum is formed inside the ejector for sludge reflux. The alum flower particles in the sludge are an adsorbent and can adsorb the suspended substances and the precipitates generated by the reaction in the water, so that they are separated from the water.

Moreover, the sludge contains 30-40% of the unreacted agents, which can be reused for reaction, reducing the operation cost of the agents.

[0014] Two sedimentation areas are arranged inside the device for sludge sedimentation. Each sedimentation uses an electric valve to discharge sludge independently at regular intervals, which can reduce the sludge load on the inclined plates of the device and will not cause blockage or collapse of the inclined plates.

[0016] The device is provided with a cleaning port, and a cross-branch pipe type water distribution structure is adopted inside to perform regular backwashing on the inclined plate packing, reducing the sludge load on the inclined plates and greatly prolonging the service life of the inclined plates.

[0017] The backwashing period of each device is one month, and the total backwashing duration is 30 minutes. The backwashing uses the effluent of other devices and does not require an external clean water source, so there is no need to increase the operation cost.

[0018] When the device is backwashed, first close the inlet and outlet electric valves, and at the same time open the sludge discharge valve. After draining water for 10 minutes, open the backwashing inlet electric valve. After backwashing for 20 minutes, close the backwashing inlet valve and the sludge discharge valve, and at the same time open the outlet electric valve and the inlet electric valve to enter the normal filtration stage.

The structure is simple and reasonable, and the treatment effect is good. The negative pressure hydraulic ejector is designed based on the Venturi principle, which instantaneously reduces the water flow velocity from 4.72 m / s to 1.18 m / s, forming a vacuum inside the ejector for sludge reflux. The alum flower particles in the sludge are an adsorbent that can adsorb suspended substances and reaction-generated precipitates in the water, separating them from the water.

The backwash cycle of each device is one month, and the total backwash duration is 30 minutes. The backwash uses the effluent of other devices without the need for an external clean water source, without increasing the operation cost. When the device is backwashed, first close the inlet and outlet electric valves, and at the same time open the sludge discharge valve.
