Integrated water purification equipment

Abstract

This utility model discloses an integrated water purification device, belonging to the technical field of water purification equipment. A grid vortex reactor is installed at the water inlet on one side of the base. The grid vortex reactor has a liquid inlet pipe on its front side and multiple grid-shaped reaction chambers to change the flow direction and velocity of the raw water. In this utility model, water flows rapidly down through the auxiliary pipe. Relying on the air-carrying and ejecting effect of the water flow, the air extraction pipe continuously removes air from the siphon tube, creating a vacuum in the siphon tube. A large amount of water in the siphon riser then passes over the top of the pipe and descends along the siphon auxiliary pipe. The descending water then begins the backwashing process through the backwash inlet pipe, washing the filter media layer from bottom to top, thereby achieving backwashing of the filter media and improving the backwashing effect.

Description

Technical Field

[0001] This utility model belongs to the technical field of water purification equipment, and in particular relates to an integrated water purification equipment. Background Technology

[0002] The integrated automatic backwash water purifier features a small footprint, compact and flexible layout, fast construction cycle, low overall investment, high treatment efficiency, excellent effluent quality, and simple operation and maintenance. It is an ideal device for urban water supply and industrial and mining enterprises' water purification. The turbidity and color of the treated effluent meet the national "Standards for Drinking Water Quality." The introduction of this equipment provides a more convenient approach for small and medium-sized water purification stations in urban water supply and industrial and mining enterprises.

[0003] In traditional water purification systems, water from reservoirs or rivers is first fed into the system. The raw water undergoes flocculant treatment, which destabilizes and coagulates suspended solids in the water. This causes the suspended solids (turbidity) to settle in a rapid sedimentation tank. The effluent then passes through a quartz sand filter to remove any remaining impurities. The filtered water then enters a clear water tank, and a clear water pump delivers the purified water to the point of use. However, the water in the filter tank easily clogs the filter media. Traditional technologies use a siphon backwash to clean the filter media, but this siphon backwash results in the loss of clean water, causing waste and leaving room for improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the filter forms a siphon backwash to clean the filter media clogging impurities, but the siphon backwash will cause the loss of clean water and result in waste. Therefore, an integrated water purification device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated water purification device, including a base, the base having a flow channel, and further comprising:

[0006] A grid vortex reactor is installed at the water inlet on one side of the base. The grid vortex reactor has a liquid inlet pipe on the front side and multiple grid-shaped reaction chambers to change the flow direction and velocity of the raw water.

[0007] The reaction sedimentation zone is connected to the rear side of the corresponding grid vortex reactor at the top of the base;

[0008] Inclined tube settlers are installed in the reaction sedimentation zone, and when water flows through the inclined tube settlers, a laminar flow state is formed.

[0009] Multiple water distribution tanks are arranged in an array along the width of the reaction sedimentation zone. The water distribution tanks are located on the top side of the reaction zone chamber in the reaction sedimentation zone. Multiple filter holes are arranged in an array on both sides of the water distribution tanks to collect clarified water liquid through the filter holes.

[0010] The filtration zone is connected to the top of the base and located behind the reaction sedimentation zone. The filtration zone has multiple filtration sections, and the filtration sections are filled with filter media.

[0011] Multiple siphon risers are arranged in the filtration zone and connected to the water distribution tank by pipes. The multiple siphon risers use the siphon effect to distribute the static water from the reaction sedimentation zone into the filtration zone.

[0012] As a further description of the above technical solution:

[0013] It also includes a grid plate, which is connected to the bottom of the grid vortex reactor and the reaction sedimentation zone. The grid plate has a zigzag cross-section and is used to trap raw water.

[0014] As a further description of the above technical solution:

[0015] The mesh cyclone reactor and the bottom of the reaction sedimentation zone are connected by a sludge discharge pipe within the gap between the corresponding grid plates.

[0016] As a further description of the above technical solution:

[0017] It also includes: a water distribution trough, connected to the rear side of the plurality of water distribution troughs, the water distribution trough being connected to the top of the inner cavity of the filtration zone.

[0018] There are two liquid distribution tanks, which are placed opposite each other on both sides of the water distribution tank. The two liquid distribution tanks are located at the top of the same row of multiple filtration zones.

[0019] As a further description of the above technical solution:

[0020] A drain pipe is connected to the top of the end of the reaction precipitation zone.

[0021] As a further description of the above technical solution:

[0022] The siphon riser extends to the bottom of the filtration zone and is connected to a water distribution baffle.

[0023] As a further description of the above technical solution:

[0024] It also includes: a siphon auxiliary pipe, which is connected to one side of the siphon riser pipe, and one end of the siphon auxiliary pipe outlet extends into the top cavity of the base.

[0025] A vacuum pump is located at the top of the inner cavity of the siphon auxiliary pipe. The vacuum pump draws water from the siphon riser pipe to accelerate the formation of the siphon.

[0026] Multiple backwash inlet pipes are arranged on the side wall of the filtration zone near the siphon auxiliary pipe inlet. The backwash liquid flowing out of the siphon auxiliary pipe inlet is introduced into the bottom side of the filtration zone for backwashing through the backwash inlet pipes.

[0027] The water distribution system is connected to the bottom of the filtration zone and absorbs the filtered water from the bottom of the filtration zone.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0029] In this invention, the designed siphon riser and siphon auxiliary port allow for the control of a vacuum pump to draw water from the top of the siphon auxiliary port. This vacuum pump accelerates the formation of the siphon by drawing water from the siphon riser, raising the water level in the siphon riser to the siphon auxiliary port. As the water riser rises, it flows rapidly down the siphon auxiliary port. The air-carrying and ejecting effect of the water flow continuously removes air from the siphon riser, creating a vacuum. A large amount of water then flows over the top of the siphon riser and down the siphon auxiliary port. The descending water then enters the backwashing process through the backwash inlet pipe, washing the filter media layer from bottom to top. This process effectively backwashes the filter media and improves the backwashing effect. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-4 This utility model provides a technical solution: an integrated water purification device, including a base 1, the base 1 having a flow channel, and further including:

[0037] The grid vortex reactor 2 is installed at the water inlet position on one side of the base 1. The grid vortex reactor 2 has a liquid inlet pipe on the front side and multiple grid-shaped reaction chambers to change the flow direction and velocity of the raw water.

[0038] The reaction precipitation zone 3 is connected to the rear side of the grid vortex reactor 2 at the top of the base 1;

[0039] An inclined tube settler is installed in the reaction sedimentation zone 3. When water flows through the inclined tube settler, it forms a laminar flow state.

[0040] Multiple water distribution tanks 5 are arranged in an array along the width of the reaction sedimentation zone 3. The water distribution tanks 5 are located on the top side of the reaction zone chamber of the reaction sedimentation zone 3. Multiple filter holes 11 are arranged in an array on both sides of the water distribution tanks 5 for collecting clarified water liquid through the filter holes 11.

[0041] The filter zone 4 is connected to the top of the base 1 and is located behind the reaction precipitation zone 3. The filter zone 4 has multiple filter zones 4, and the filter zones 4 are filled with filter media.

[0042] Multiple siphon risers 7 are arranged in the filtration zone 4. The multiple siphon risers 7 are connected to the water distribution tank 5 through pipes. The multiple siphon risers 7 arrange the static water liquid in the reaction sedimentation zone 3 in the filtration zone 4 through the siphon effect.

[0043] Specifically, when the water is pumped into the grid vortex reactor 2 for reaction, the raw water with added chemicals can be fully mixed by colliding with the grid through the grid vortex reactor 2, constantly changing the flow direction and velocity of the raw water. By its own hydraulic action, the added coagulant is further mixed with the influent. The colloids in the water then adsorb other colloids under the action of the coagulant and collide with each other in the grid, gradually forming large flocs, which can save the amount of chemicals added.

[0044] It also includes a grid plate 9, which is connected to the bottom of the grid cyclone reactor 2 and the reaction sedimentation zone 3. The grid plate 9 has a zigzag cross-section and is used to trap raw water.

[0045] The mesh cyclone reactor 2 and the reaction sedimentation zone 3 are connected by a sludge discharge pipe 10 in the gap between the grid plate 9 at the bottom.

[0046] By designing the sludge discharge pipe 10 and the grid plate 9, the large particles that settle can be blocked by the grid plate 9, which is beneficial to improving the interception effect.

[0047] Furthermore, the water entering the rear reaction sedimentation zone 3 can contact the inclined tube settler within the reaction sedimentation zone 3. Due to the small spacing between the inclined tubes and the small pipe diameter, the water flow becomes laminar here. When the water flows in its respective inclined tube, each layer is separated and does not interfere with each other. The settling of solid particles in the water is therefore not disturbed by the water flow and can settle easily. In addition, since the inclined tubes increase the sedimentation area, when the interception velocity (settling velocity) of the sedimentation tank is the same, the amount of water treated is increased.

[0048] Water distribution trough 12 is connected to the rear side of the plurality of water distribution troughs 5, and water distribution trough 12 is connected to the top of the inner cavity of the filtration zone 4.

[0049] There are two liquid separation tanks 6, which are placed opposite each other on both sides of the water distribution tank 5. The two liquid separation tanks 6 are located at the top of the same row of multiple filtration zones 4. The top end of the reaction sedimentation zone 3 is connected to a drain pipe 13.

[0050] The siphon riser pipe 7 extends to the bottom of the filtration zone 4 and is connected to a water distribution baffle.

[0051] It also includes: a siphon auxiliary pipe port 8, which is connected to one side of the siphon riser pipe 7, and one end of the siphon auxiliary pipe port 8 extends into the top cavity of the base 1.

[0052] A vacuum pump is located at the top of the inner cavity of the siphon auxiliary pipe 8. The vacuum pump draws water from the siphon riser pipe 7 to accelerate the formation of the siphon.

[0053] Multiple backwash inlet pipes 14 are arranged on the side wall of the filter zone 4 near the siphon auxiliary pipe port 8. The backwash liquid flowing out of the siphon auxiliary pipe port 8 is introduced into the bottom side of the filter zone 4 for backwashing through the backwash inlet pipes 14.

[0054] The water distribution system is connected to the bottom of the filtration zone 4 and absorbs the filtered water from the bottom of the filtration zone 4.

[0055] After sedimentation and clarification, the clear water enters the siphon riser 7 through the water distribution tank 12, the liquid distribution tank 6, and the bottom pipe of the liquid distribution tank 6. The bottom pipe of the liquid distribution tank 6 extends to one side of the siphon riser 7, and the siphon riser 7 extends to the filtration zone 4. After the raw water enters, the water distribution baffle at the end of the siphon riser 7 distributes the water evenly into the filter media layer. The water is filtered from top to bottom through the filter media layer. The filtered water enters the water collection area, i.e. the outlet tank, from the water distribution system. When the water level rises to the outlet pipe, the filtered water flows into the clear water pool through the outlet pipe.

[0056] The water distribution system delivers clean water from the bottom to the collection area by suction. The water distribution system includes corresponding pipes and a suction pump to ensure the drainage needs are met.

[0057] When the filter is first put into operation, the filter media layer is relatively clean. However, after a certain period of operation, the head loss increases due to the gradual increase of solid particles and impurities in the filter media layer. As the inlet resistance increases, the liquid level in the siphon riser pipe 7 connected to the inlet area also slowly rises.

[0058] When the head loss increases to a certain extent, the vacuum pump is controlled to draw water from the top of the inner cavity of the siphon auxiliary pipe 8. The vacuum pump draws water from the siphon riser pipe 7 to accelerate the formation of the siphon, causing the water level in the siphon riser pipe 7 to rise to the siphon auxiliary pipe 8. The water then flows rapidly down the siphon auxiliary pipe 8. Relying on the air-carrying and ejecting effect of the water flow, the siphon auxiliary pipe 8 continuously removes the air from the siphon riser pipe 7, creating a vacuum in the siphon riser pipe 7. A large amount of water in the siphon riser pipe 7 then passes over the top of the pipe and falls down the siphon auxiliary pipe 8. The falling water begins the backwashing process through the backwash inlet pipe. The water washes the filter media layer from bottom to top, and the wastewater from the wash is discharged through the drain pipe 13.
