Technical Field

[0001] The present invention relates to a temperature control and pH adjustment device, in particular to an integrated temperature control and pH adjustment device for boiler wastewater pretreatment, belonging to the technical field of boiler wastewater treatment. Background Art

[0002] Temperature control and pH adjustment in boiler wastewater pretreatment are the core links to ensure the stable operation of the subsequent treatment system: by adjusting the water temperature to an appropriate range (such as 20 - 40 °C), temperature control can not only protect equipment from high-temperature damage, but also optimize the efficiency of biochemical reactions, membrane treatment and other processes. At the same time, waste heat recovery is used to reduce energy consumption; pH adjustment controls the acidity and alkalinity of the wastewater within the target range (such as neutral 6.5 - 8.5) by adding acid and alkali agents to prevent pipeline scaling and equipment corrosion, and create the best reaction conditions for subsequent processes such as flocculation, biochemical treatment, and membrane separation. The combined action of the two ensures that the pretreatment effect meets the standards and improves the economy and reliability of the overall system operation.

[0003] Currently, during the process of regulating water temperature and pH, although an automated control method is adopted, which can accurately calculate the proportioning amount, the production and input costs of the equipment are relatively high. Moreover, during the pretreatment process, an electric stirring device is required to operate to ensure the uniformity of temperature and pH in the wastewater, and a large amount of energy is consumed during use.

[0004] Therefore, an integrated temperature control and pH adjustment device for boiler wastewater pretreatment is designed to optimize the above problems. Summary of the Invention

[0034] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0035] like Figures 1-8 As shown, this embodiment provides an integrated temperature control and pH adjustment device for boiler wastewater pretreatment, comprising a treatment box 1, a liquid inlet 101 opened at the top of one side of the treatment box 1, a liquid discharge port 102 opened at the middle position of the other side of the treatment box 1, and a thermometer 103 and a pH meter 104 installed inside the treatment box 1 near the liquid discharge port 102, a temperature adjustment mechanism 2 is installed at a position near the liquid inlet 101 inside the treatment box 1, a volute 3 is provided at the middle position of the top of the treatment box 1, a conduit 6 is fixed to the bottom end of the volute 3, a shaft 4 is vertically installed inside the conduit 6, an impeller 5 is installed on the shaft 4, a spiral plate 7 is provided at the inner bottom of the treatment box 1, the conduit 6 extends to the inside of the spiral plate 7, a stirring mechanism 8 is provided inside the spiral plate 7, an acid adding mechanism 9 is provided at the top of the treatment box 1, and the stirring mechanism 8 and the acid adding mechanism 9 are driven by the shaft 4.

[0036] Overall working principle: After the alkaline boiler wastewater enters the interior of the treatment tank 1 from the liquid inlet 101, it first passes through the temperature adjustment mechanism 2, where the cooling water source is mixed into the boiler wastewater to reduce the temperature of the wastewater. When the cooling water source is mixed with the wastewater, they enter the interior of the volute 3 together, and then are discharged from the interior of the volute 3. The water flow impacts the impeller 5, controlling the rotation of the shaft rod 4. When the shaft rod 4 drives the impeller 5 to rotate, the liquid is preliminarily mixed. At the same time, during the rotation of the shaft rod 4, the acid addition mechanism 9 is controlled to start, injecting acidic liquid into the wastewater. Then, the wastewater and the acidic solution are discharged from the bottom of the conduit 6 and fall between the spiral plates 7. The spiral plates 7 are used to extend the residence time of the wastewater in the treatment tank 1. At the same time, the rotation of the stirring mechanism 8 is driven by the shaft rod 4 to increase the agitation effect on the liquid, so as to ensure the uniformity of temperature control and pH adjustment. After thorough mixing, the waste liquid is finally detected by the thermometer 103 and the pH meter 104, and then discharged from the liquid outlet 102.

[0037] In this embodiment, the temperature adjustment mechanism 2 includes a delivery pipe 201, a first through port 202, a sliding sleeve 203, a second through port 204, a memory spring 205, an annular pipe 206, and a cold water pipe 207. The delivery pipe 201 is fixed between the end of the liquid inlet 101 and the volute 3. An annular pipe 206 is provided on the outer side of the delivery pipe 201. First through ports 202 that are communicated with the interior of the annular pipe 206 are evenly opened on the outer side of the delivery pipe 201. A cold water pipe 207 is installed on the top of the annular pipe 206, and the cold water pipe 207 is communicated with the cold water pipeline. A sliding sleeve 203 is slidably arranged inside the delivery pipe 201. Second through ports 204 that cooperate with the first through ports 202 are evenly opened on the sliding sleeve 203. A memory spring 205 is provided between the sliding sleeve 203 and the end of the delivery pipe 201.

[0038] Local working principle: When the high-temperature wastewater enters the interior of the delivery pipe 201, the memory spring 205 will elongate, pushing the sliding sleeve 203 to slide inside the delivery pipe 201, increasing the area where the second through port 204 is aligned with the first through port 202. The cooling water source always enters the interior of the annular pipe 206 through the cold water pipe 207, and then enters the interior of the delivery pipe 201 through the communication port of the second through port 204 and the first through port 202, completing the automatic replenishment of cold water. The memory spring 205 is made of nickel-titanium shape memory alloy, with an initial length of L0, in a natural state at 20°C, and an elongation of ΔL = 5mm when the temperature rises to 30°C, pushing the sliding sleeve 203 to slide away from the liquid inlet 101. When the temperature is lower than 25°C, the spring returns to its initial state. A longitudinal chute that cooperates with the convex ribs on the inner wall of the delivery pipe 201 is provided on the outer wall of the sliding sleeve 203 to ensure that the sliding sleeve 203 only slides axially without rotating. A polytetrafluoroethylene sealing ring is provided on the contact surface between the sliding sleeve 203 and the delivery pipe 201 to prevent wastewater leakage.

[0039] In this embodiment, the apertures of the first through port 202 and the second through port 204 are of the same size, and four groups of the first through port 202 and the second through port 204 are provided respectively.

[0040] Local working principle: Cold water passes through between multiple groups of through holes and can quickly blend into the wastewater, so as to improve the mixing rate.

[0041] In this embodiment, the inner diameter of the sliding sleeve 203 near one end of the memory spring 205 is smaller than that of the other end, and a limiting groove is provided at one end of the sliding sleeve 203 near the memory spring 205.

[0042] Local working principle: After the wastewater and cold water are mixed, the water flow rate will increase. By expanding the inner diameter of one end of the sliding sleeve 203, the water pressure can be ensured to be stable. The setting of the limiting groove can ensure the connection stability between the sliding sleeve 203 and the memory spring 205.

[0043] In this embodiment, the stirring mechanism 8 includes a reciprocating lead screw 801, a slider 802, a spiral rod 805 and a vertical guiding assembly. The reciprocating lead screw 801 is rotatably installed at the inner bottom of the treatment tank 1, and the top end of the reciprocating lead screw 801 is fixedly connected to the shaft rod 4. A slider 802 is arranged on the reciprocating lead screw 801, and a vertical guiding assembly for controlling the linear movement of the slider 802 is arranged on the side of the reciprocating lead screw 801. A spiral rod 805 is fixedly connected to the side of the slider 802, and the spiral rod 805 is located inside the spiral plate 7.

[0044] Local working principle: When the shaft rod 4 rotates, it will drive the reciprocating lead screw 801 to rotate. Due to the limiting effect of the vertical guiding assembly on the slider 802, the rotation of the reciprocating lead screw 801 controls the vertical reciprocating movement of the slider 802. The slider 802 drives the spiral rod 805 to move up and down during the movement, so as to accelerate the mixing of the solution.

[0045] In this embodiment, the vertical guiding assembly includes a guide block 803 and a vertical rod 804. The guide block 803 is fixedly connected to the side of the slider 802, and a vertical rod 804 is vertically slidably arranged inside the guide block 803. The bottom end of the vertical rod 804 is fixedly connected to the inner bottom of the treatment tank 1.

[0046] Local working principle: The guide block 803 can only move along the length direction of the vertical rod 804, and thus the slider 802 can only move vertically.

[0047] In this embodiment, fixing rings 806 are uniformly fixed on the outer side of the spiral rod 805, and stirring plates 807 are symmetrically fixed on the outer sides of the fixing rings 806, and the stirring plates 807 are parallel to the horizontal plane.

[0048] Local working principle: During the up and down movement of the spiral rod 805, it will drive the stirring plates 807 to move up and down at the same time, so as to stir the solution and improve the mixing effect.

[0049] In this embodiment, the acid adding mechanism 9 includes a protective shell 901, a storage tank 902, a through hole 903 and a pumping and discharging assembly. The protective shell 901 is fixed on the top of the processing tank 1. A storage tank 902 is provided on the top of the protective shell 901. The through hole 903 is vertically opened inside the shaft rod 4, and diffusion openings are provided at both the top end and the bottom end of the through hole 903. The diffusion opening at the bottom of the through hole 903 is located inside the volute 3, and the diffusion opening at the top of the through hole 903 is located inside the protective shell 901. A pumping and discharging assembly is provided between the storage tank 902 and the diffusion opening at the top of the through hole 903.

[0050] Partial working principle: When the shaft rod 4 rotates, it will control the operation of the pumping and discharging assembly, extract the acid liquid from the inside of the storage tank 902, inject it into the inside of the through hole 903 from the diffusion opening at the top of the through hole 903, and then discharge it to the inside of the volute 3 from the diffusion opening at the bottom of the through hole 903 to neutralize the waste liquid.

[0051] In this embodiment, the pumping and discharging assembly includes a transfer box 904, a turntable 905, a rotating rod 906, a cylinder body 907, a push-pull rod 908 and a piston 909. The transfer box 904 is fixed on the inner bottom of the protective shell 901, and the shaft rod 4 vertically passes through the transfer box 904 and is rotatably connected to the transfer box 904. The diffusion opening at the top end of the through hole 903 is communicated with the inside of the transfer box 904. The turntable 905 is horizontally fixed on the top end of the shaft rod 4. A rotating rod 906 is rotatably installed on one side of the top of the turntable 905. The cylinder bodies 907 are symmetrically installed on the inner side of the protective shell 901. Push-pull rods 908 are slidably installed inside the cylinder bodies 907. Push-pull rods 908 are hinged between the side edges of the push-pull rods 908 and the rotating rod 906. A one-way liquid inlet pipe is provided between the end of the cylinder body 907 and the storage tank 902, and a one-way liquid discharge pipe is provided between the end of the cylinder body 907 and the transfer box 904.

[0052] Partial working principle: When the shaft rod 4 rotates, it controls the rotation of the turntable 905. The rotating rod 906 on the turntable 905 drives the two push-pull rods 908 to move, and can respectively extract the acid liquid inside the storage tank 902 into the inside of the cylinder body 907 and discharge the liquid inside the cylinder body 907 into the inside of the transfer box 904. The extraction and discharge of the acid liquid are carried out simultaneously, which can ensure the continuous injection of the acid liquid inside the transfer box 904. The acid liquid injected into the inside of the transfer box 904 enters the inside of the through hole 903 from the diffusion opening at the top end of the through hole 903.

[0053] In this embodiment, a stirring motor is provided on the top of the storage tank 902, and a stirring rod is provided at the output end of the stirring motor.
