Description

Technical Field

[0001] The invention relates to the technical field of water treatment, recycling and reuse, and in particular to a water treatment, recycling and reuse device for a power plant. Background Art

[0002] High-speed mixed bed is a kind of equipment that can remove salt substances (i.e. various anions and cations) in water, and can also remove impurities such as suspended matter and colloids leaked from the pre-filter. High-speed mixed bed mainly removes impurity ions in water through the ion exchange of anion and cation exchange resins. When the water to be treated enters the high-speed mixed bed, the cations in the water exchange with the anions on the resin, and the anions in the water exchange with the cations on the resin, so that the salt, hardness, pH, etc. in the water are effectively reduced, achieving the purpose of purifying water quality.

[0003] In the related art, when water is recycled, the contact time between water and resin in the reaction barrel is too short, resulting in incomplete ion exchange between the resin and water. At the same time, when water falls into the resin layer, it deviates due to its inertia, which easily causes one part of the resin layer to be full while the other part is not full, resulting in low efficiency of the device. At the same time, the water purification efficiency of a single reaction barrel is not high, which greatly reduces the practicality of the device. Summary of the invention

Under the action of the first special-shaped gear 67 and the first rack 65, the connecting member 62 moves leftward so that The connecting member 62 drives the second baffle plate 64 to move into the shell 61, thereby separating the second baffle plate 64 and the second blocking member 52, so that the second blocking member 52 moves upward under the action of the second elastic member 51 to be in a blocking state, or the second special-shaped gear 68 is provided on the second baffle plate 64, when the second baffle plate 64 rotates from a vertical position to a horizontal position, the second baffle plate 64 rotates to drive the second special-shaped gear 68 to rotate, under the action of the second special-shaped gear 68 and the second rack 66, the connecting member 62 moves to the right so that the connecting member 62 drives the first baffle plate 63 to move into the shell 61, thereby separating the first baffle plate 63 and the first blocking member 42, so that the first blocking member 42 moves upward under the action of the first elastic member 41 to be in a blocking state.

[0043] The first torsion spring is arranged between the first baffle plate 63 and the connecting member 62, so that when the first baffle plate 63 rotates from the horizontal position to the vertical position, the first torsion spring has a first driving force to drive the first baffle plate 63 to rotate from the vertical position to the horizontal position. The second torsion spring is arranged between the second baffle plate 64 and the connecting member 62, so that when the second baffle plate 64 rotates from the horizontal position to the vertical position, the second torsion spring has a second driving force to drive the second baffle plate 64 to rotate from the vertical position to the horizontal position.

[0044] Specifically, the first torsion spring is arranged on the rotating shaft between the first baffle plate 63 and the connecting member 62, and the two ends of the first torsion spring are respectively connected to the first baffle plate 63 and the connecting member 62, and the second torsion spring is arranged on the rotating shaft between the second baffle plate 64 and the connecting member 62, and the two ends of the second torsion spring are respectively connected to the second baffle plate 64 and the connecting member 62. Therefore, when the first baffle 63 rotates to a vertical state and the first sealing member 42 moves to the bottom of the first baffle 63 under the action of the reaction water, the first baffle 63 reverses under the action of the first torsion spring, so that the first baffle 63 moves from a vertical position to a horizontal position. Due to the engagement of the first special-shaped gear 67 and the first rack 65, the connecting member 62 moves to the right to allow the second baffle 64 to extend out of the shell 61. Similarly, when the second baffle 64 rotates to a vertical state and the first sealing member 42 moves to the bottom of the second baffle 64 under the action of the reaction water, the second baffle 64 reverses under the action of the second torsion spring, so that the second baffle 64 moves from a vertical position to a horizontal position. Due to the engagement of the second special-shaped gear 68 and the second rack 66, the connecting member 62 moves to the left to allow the first baffle 63 to extend out of the shell 61.

[0045] In some embodiments, the first connecting member 3 includes a first tube 31, a second tube 32, a third tube 33, a first valve and a second valve. The first tube 31 and the second tube 32 are both connected to the third tube 33. The first valve is arranged in the first tube 31 and the first tube 31 is connected to the first cavity 11. The second valve is arranged in the second tube 32 and the second tube 32 is connected to the third cavity 21. In the first state, the first valve is opened and the second valve is closed. In the second state, the first valve is closed and the second valve is opened. Specifically, as Figure 1 and Figure 2 As shown, the third tube 33 is a vertical tube extending in the up-down direction, the first tube 31 and the second tube 32 are respectively arranged on the left and right sides of the third tube 33 and are both connected to the third tube 33, the first tube 31 and the second tube 32 are respectively connected to the first cavity 11 and the second cavity 12, the first valve and the second valve can be battery valves respectively arranged in the first tube 31 and the second tube 32, thereby, the first state and the second state of the first connecting member 3 are controlled by the first valve and the second valve, so that in the first state, the first valve is opened and the second valve is closed, so that the reaction water flows into the first reaction barrel 1, and in the second state, the first valve is closed and the second valve is opened, so that the reaction water flows into the second reaction barrel 2.

[0046] In some embodiments, the power plant water treatment device 100 further includes a first filter element 7 and a second filter element 8, which are respectively disposed in the first reaction barrel 1 and the second reaction barrel 2, the first filter element 7 being located above the purification medium 10 of the first reaction barrel 1, and the second filter element 8 being located above the purification medium 10 of the second reaction barrel 2. Specifically, Figure 2As shown, the first filter element 7 and the second filter element 8 are both filter plates and are respectively arranged in the first reaction barrel 1 and the second reaction barrel 2. The first filter element 7 is arranged above the purification medium 10 of the first reaction barrel 1, and the second filter element 8 is arranged above the purification medium 10 of the second reaction barrel 2. Therefore, large particles of impurities such as sand and soil in the reaction water are removed by the first filter element 7 and the second filter element 8, and large particles of impurities are prevented from entering the purification medium 10 or subsequent treatment equipment, thereby extending the service life of the equipment, reducing the load of the subsequent treatment equipment, and improving the overall water treatment efficiency.

[0047] In some embodiments, the first reaction barrel 1 further comprises a fifth chamber 13, the fifth chamber 13 is located below the second chamber 12 and communicated with the second chamber 12, and the fifth chamber 13 is used to store the reaction water purified by the purification medium 10, and the second reaction barrel 2 further comprises a sixth chamber 23, the sixth chamber 23 is located below the fourth chamber 22 and communicated with the fourth chamber 22, and the sixth chamber 23 is used to store the reaction water purified by the purification medium 10. Specifically, Figure 2 As shown, the fifth chamber 13 is arranged below the second chamber 12 and is connected to the second chamber 12. When the reaction water in the second chamber 12 is purified, it can flow into the fifth chamber 13 to store and collect the reaction water. The sixth chamber 23 is arranged below the fourth chamber 22 and is connected to the fourth chamber 22. When the reaction water in the fourth chamber 22 is purified, it can flow into the sixth chamber 23 to store and collect the reaction water.

[0048] In some embodiments, the power plant water treatment device 100 further includes a second connecting piece 9, which is connected to the fifth chamber 13 and the sixth chamber 23 respectively, so that the reaction water in the fifth chamber 13 and the sixth chamber 23 can be discharged through the second connecting piece 9. Figure 2 As shown, the second connecting piece 9 can be a three-way pipe and a battery valve is provided in the second connecting piece 9. The second connecting piece 9 is connected to the fifth chamber 13 and the sixth chamber 23 respectively, thereby discharging the purified reaction water in the first reaction barrel 1 and the second reaction barrel 2 through the three-way pipe.

[0049] The working process of the power plant water treatment device 100 of the embodiment of the present invention is as follows:

[0050] When the device starts to run, the first valve inside the left liquid inlet valve is opened, and the water flows into the first reaction barrel 1 on the left first. Due to the action of the first blocking piece 42, the water gathers at the upper ends of the first reaction barrel 1 and the second reaction barrel 2. Under the action of the first telescopic rod, the gravity of the water becomes larger and larger, causing the first blocking piece 42 to slowly move downward. When the first blocking piece 42 falls to the upper end of the first baffle 63, the first baffle 63 turns counterclockwise, and the first blocking piece 42 slowly falls. The water flow at the upper end of the first blocking piece 42 slowly flows into the middle of the second chamber 12 through the gap between the first blocking piece 42 and the first chamber 11 for resin adsorption reaction. When the first baffle 63 on the left turns to a certain angle, the first The lower end of the baffle 63 triggers the control switch on the reflux plate, so that the solenoid valve inside the liquid inlet valve closes the left liquid inlet and opens the right liquid inlet, allowing the water to flow into the second reaction barrel 2 on the right. At this time, the water flow at the upper end of the first blocking piece 42 on the left all flows through the gap between the first blocking piece 42 and the first chamber 11 into the middle of the second chamber 12 for resin adsorption reaction. At this time, the first blocking piece 42 on the left is located at the lower end of the first baffle 63 but does not hinder the first baffle 63 from resetting. The first baffle 63 returns to a horizontal state. Similarly, under the action of the second telescopic rod, since the right liquid inlet is opened, the gravity of the water in the second reaction barrel 2 on the right becomes larger and larger, causing the second blocking piece 52 to slowly move downward. When the second blocking piece 52 falls to When the second baffle plate 64 is at the upper end, the second baffle plate 64 flips clockwise, and the second baffle plate 64 drives the second special-shaped gear 68 to rotate. The second special-shaped gear 68 meshes with the second special-shaped gear 68 to drive the sliding to the right side of the connecting member 62, so that the first blocking member 42 on the left side moves upward to the upper end of the first baffle plate 63 on the left side, and the second blocking member 52 on the right side slowly falls, causing the water flow at the upper end of the second blocking member 52 on the right side to slowly flow into the middle part of the fourth chamber 22 through the gap between the second blocking member 52 and the third chamber 21 for resin adsorption reaction. When the second baffle plate 64 on the right side flips to a certain angle, the lower end of the second baffle plate 64 on the right side triggers the control switch on the reflux plate, so that the solenoid valve inside the liquid inlet valve turns the liquid inlet on the right side to the liquid inlet port 42 on the right side. Close and open the left liquid inlet to let the water flow into the left first chamber 11. At this time, all the water flow at the upper end of the second blocking piece 52 on the right side flows into the middle of the second reaction barrel 2 through the gap between the second blocking piece 52 and the third chamber 21 for resin adsorption reaction. At this time, the second blocking piece 52 on the right side is located at the lower end of the second baffle 64 but does not hinder the second baffle 64 from resetting. The second baffle 64 restores to a horizontal state and reciprocates. Through the action of the second baffle 64, the solenoid valves inside the liquid inlet valves at the upper ends of the first reaction barrel 1 and the second reaction barrel 2 are alternately opened, thereby realizing the alternating operation of the first reaction barrel 1 and the second reaction barrel 2, increasing the contact time between water and the resins in the first reaction barrel 1 and the second reaction barrel 2, and realizing efficient operation.
