Description

TECHNICAL FIELD

[0001] The present application relates to the field of flocculation and sedimentation, in particular to a seawater pretreatment equipment. BACKGROUND

[0002] The purpose of seawater purification is to remove suspended solids, dissolved salts, organic matter and microorganisms and other impurities in seawater to meet the standards of industrial water, agricultural irrigation and even drinking water. Traditional seawater purification methods include reverse osmosis, distillation, electrodialysis and the like. Flocculation and sedimentation tank is a water treatment technology combining physical and chemical methods, which can remove suspended particles in water by adding flocculants to make them aggregate into larger flocs, and then removing them by sedimentation or filtration. This water treatment technology can be applied in the pretreatment of seawater purification.

[0003] The commonly used sedimentation equipment at present is inclined plate sedimentation tank, which is divided into counterflow inclined plate sedimentation tank, co-current inclined plate sedimentation tank and lateral flow inclined plate sedimentation tank. Among them, the counterflow inclined plate sedimentation tank is the most commonly used, the direction of water flow in it is opposite to the moving direction of the sediment particles. Generally, the water flow is from bottom to top, while the sediment particles are from top to bottom. The inclined plate is generally placed at an angle of 60°, which is helpful for particle sedimentation and suitable for turbidity of raw water. For the co-current inclined plate sedimentation tank, the direction of water flow is from top to bottom, which is consistent with the sliding direction of the sediment sludge. The inclined angle of the inclined plate is generally 30°-40°. Because the water flow downward promotes the sliding of the sediment sludge, and the sedimentation area is increased due to the reduction of the inclined angle of the inclined plate, the sedimentation efficiency is improved. The co-current inclined plate sedimentation tank is generally applied to the sedimentation of raw water with lower turbidity.

[0004] Due to the influence of factors such as flocculant dosage, water temperature, flow rate and seawater quality, the turbidity of seawater after preliminary flocculation treatment is not certain. In the prior art, a single type of inclined plate sedimentation tank with fixed angle is generally used to deal with sewage with different turbidity, which may reduce the treatment efficiency of sewage. Therefore, there is an urgent need to propose a seawater pretreatment equipment. SUMMARY

The sludge discharge device 102 comprises a plurality of sludge hoppers 102a and a sludge discharge pipe 102b communicating the plurality of sludge hoppers 102a. The sludge flows into the hopper under the action of gravity, and when the sludge in the hopper accumulates to a certain extent, it is discharged outside the tank through the sludge discharge pipe 102b.

[0040] The sedimentation tank 101 is provided with a plurality of inclined plates 200, and the plurality of inclined plates 200 are arranged in parallel with each other. An adjusting assembly 400 is arranged on the side surface of the inclined plate 200, and the adjusting assembly 400 can switch the angle of the inclined plate 200. A switching assembly 300 is arranged between the flocculation tank 100 and the sedimentation tank 101, and the switching assembly 300 can switch the path of the treated sewage from the flocculation tank 100 into the sedimentation tank 101, thereby changing the form of the sedimentation tank 101, switching between co-current flow and counter-current flow.

When the form of the sedimentation tank 101 changes, the adjusting assembly 400 is used to change the inclination angle of the inclined plate 200 to adapt to the sedimentation tank 101 of different forms.

[0041] The flocculation tank 100 adopts a vertical flow turbulent flocculation tank 100, and a wing plate partition flocculation device is placed in the vertical flow channel. The treated sewage from the flocculation tank 100 enters the sedimentation tank 101 through the switching assembly 300. After the sewage is deposited by the inclined plate 200, the sludge is deposited into the sludge hopper, and then discharged through the sludge discharge pipe 102b. The clear water moves upward into the perforated water collecting tank 103, and then is discharged through the water outlet tank 104.

[0047] The rest of the structure is the same as that of Example 1.

[0048] Example 3

[0049] With reference to Figures 3-7 For the third embodiment of the application, which is different from the second embodiment, the adjusting assembly 400 comprises two regulating parts 401 arranged on the inclined plate 200, the two regulating parts 401 are symmetrically arranged on the two sides of the inclined plate 200, the adjusting assembly 400 further comprises a transmission part 402 arranged on one of the regulating parts 401, and a locking part 403 arranged on the transmission part 402; wherein the adjusting assembly 400 is arranged on the side wall of the sedimentation tank 101.

[0055] Referring to Figure 6, the slider 403c-6 and the sliding slot 403c-5 are both arranged in a left-low and right-high manner, the spring 403c-9 makes the clamping block 403c-4 engage on the gear 403a in the normal state, the slider 403c-6 is controlled to move left, the slider 403c-6 can drive the movable rod 403c-3 and the clamping block 403c-4 to move up through the sliding slot 403c-5, so that the clamping block 403c-4 is separated from the surface of the gear 403a, the rotating rod 402a is rotated to the appropriate position, and then the control block is released, the spring 403c-9 makes the movable rod 403c-3 and the clamping block 403c-4 return to the original position, the clamping block 403c-4 is re-engaged with the gear 403a, and the slider 403c-6 also returns to the original state.
