Description

Technical Field

[0001] This utility model relates to the field of automatic temperature control technology, and in particular to an adaptive temperature adjustment device for polyaluminum chloride reaction. Background Technology

[0002] According to Chinese Publication No. CN219958110U, an automatic temperature control device for a polyaluminum chloride reactor is disclosed, relating to the field of automatic temperature control technology. The device includes a base, a reactor shell on top of the base, a reactor inner liner inside the reactor shell, a reactor lid on top of the reactor inner liner, a sealing gasket between the reactor lid and the reactor inner liner, a drive motor at the top center of the reactor lid, a viewing window on one side of the top of the reactor lid, a charge-coupled device at the top of the viewing window, a power supply box on one side of the top of the base, a control panel on the top of the power supply box, a signal receiver on one side of the control panel, and a thermocouple at the bottom of the inner wall of the reactor inner liner, with a signal transmitter on top of the thermocouple. The device uses thermocouples to sense the internal temperature of the reactor. When the temperature is too high or too low, the temperature is adjusted by increasing or decreasing the steam flow rate at the steam inlet, eliminating the need for manual intervention and reducing workload.

[0003] The reactors described above and in the prior art are mostly connected to steam via a coil, and the internal temperature of the reactor is controlled by the heat transfer of the high-temperature steam. However, the length of the coil in the prior art is fixed at the time of manufacture. However, the amount of polyaluminum chloride reacting with wastewater in the reactor is not fixed during use. When the amount of polyaluminum chloride reacting with wastewater is small, an excessively long coil will cause energy waste. The above-mentioned technologies cannot adjust the length of the coil according to the amount of polyaluminum chloride reacting with wastewater. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the length of the coil according to the amount of polyaluminum chloride reacting with wastewater, and to propose an adaptive temperature control device for the polyaluminum chloride reaction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polyaluminum chloride reaction temperature adaptive adjustment device, comprising a reaction vessel, a vessel lid on the top of the reaction vessel, a temperature sensor on the top of the vessel lid, a first coil wound around the outside of the reaction vessel, a second coil on the top of the first coil, a third coil on the top of the second coil, two fixing buckles on both sides of the first, second, and third coils, two three-way ball valves on one side of the reaction vessel, a first connecting pipe between the two three-way ball valves, a first L-shaped gas supply pipe on one side of the first coil, a second L-shaped gas supply pipe on one side of the third coil, a second connecting pipe on the side of the reaction vessel away from the three-way ball valves, and a gas outlet on the surface of the second connecting pipe away from the reaction vessel.

[0006] Preferably, the vessel cover is installed on the top surface of the reactor and is connected to the reactor flange.

[0007] Preferably, the temperature sensor is installed on the top surface of the vessel lid and is connected to the flange of the vessel lid, with one end of the temperature sensor penetrating into the vessel lid.

[0008] Preferably, the first, second, and third coils are all wound around the outer surface of the reactor, and the first, second, and third coils are all installed on the outer surface of the reactor by four fixing buckles, with the first, second, and third coils being arranged at equal intervals.

[0009] Preferably, the vertical centerlines of the two three-way ball valves are aligned, and both three-way ball valves are connected to the flanges of the first and second serpentine tubes.

[0010] Preferably, both ends of the first connecting pipe are connected to two three-way ball valve flanges, and the second connecting pipe is connected to the flange at the end of the first, second, and third coiled tubes furthest from the three-way ball valves.

[0011] Preferably, the first L-shaped gas supply pipe and the second L-shaped gas supply pipe are mirror-symmetrically arranged with the first connecting pipe as the center, and both the first L-shaped gas supply pipe and the second L-shaped gas supply pipe are connected to the flange of the three-way ball valve.

[0012] Beneficial effects

[0013] In this invention, an external steam source is connected to a first L-shaped gas delivery pipe, and the steam is then delivered through the first L-shaped gas delivery pipe to a three-way ball valve connected to a first coiled tube. Normally, both three-way ball valves will shut off the third gas passage, only opening the gas passage connected to the first and second coiled tubes. This ensures that steam, after passing through the bottom three-way ball valve, is only delivered into the interior of the first coiled tube, heating the bottom of the reactor. When the reaction volume in the reactor is large, the handle of the three-way ball valve is rotated, opening the gas passage connected to the first connecting pipe. This allows some steam to enter the first coiled tube after passing through the bottom three-way ball valve, while the remaining steam is delivered through the first connecting pipe to the top three-way ball valve, and then through the top three-way ball valve into the second coiled tube. Inside the reactor, the bottom and middle sections are heated via the first and second coils. When the reaction volume in the reactor is at its maximum, the handle of the three-way ball valve at the top is turned, allowing steam to pass through the valve and then be partially diverted into the second L-shaped gas delivery pipe at the top. Since the second L-shaped gas delivery pipe is connected to the third coil, a portion of the steam diverted from the three-way ball valve at the top is then transported into the interior of the third coil through the second L-shaped gas delivery pipe. The bottom, middle, and top sections of the reactor are heated simultaneously via the first, second, and third coils. By allowing steam to enter different coils, the reactor's internal reaction volume can be adjusted to accommodate different reaction volumes, thus overcoming the limitation of not being able to adjust the coil length according to the amount of polyaluminum chloride reacting with wastewater.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4 An adaptive temperature control device for polyaluminum chloride reaction includes a reactor 1, a reactor lid 2 on top of the reactor 1, a temperature sensor 13 on top of the reactor lid 2, a first coiled tube 3 wound around the outside of the reactor 1, a second coiled tube 4 on top of the first coiled tube 3, and a third coiled tube 5 on top of the second coiled tube 4. Two fixing buckles 10 are provided on both sides of the first coiled tube 3, the second coiled tube 4, and the third coiled tube 5. Two three-way ball valves 9 are provided on one side of the reactor 1, with a first connecting pipe 8 between the two three-way ball valves 9. A first L-shaped gas supply pipe 6 is provided on one side of the first coiled tube 3, and a second L-shaped gas supply pipe 7 is provided on one side of the third coiled tube 5. A second connecting pipe 11 is provided on the side of the reactor 1 away from the three-way ball valves 9, with a gas outlet 12 on the surface of the second connecting pipe 1 away from the reactor 1. The reactor lid 2 is installed on the top surface of the reactor 1 and is connected to the flange of the reactor 1. The temperature sensor 13 is installed on the reactor lid 2. The top surface is covered, and the temperature sensor 13 is connected to the flange of the vessel cover 2. One end of the temperature sensor 13 penetrates into the vessel cover 2. The first coil 3, the second coil 4, and the third coil 5 are all wrapped around the outer surface of the reactor 1. The first coil 3, the second coil 4, and the third coil 5 are all installed on the outer surface of the reactor 1 by four fixing buckles 10. The first coil 3, the second coil 4, and the third coil 5 are set at equal intervals. The vertical central axis of the two three-way ball valves 9 is consistent. The two three-way ball valves 9 are connected to the flanges of the first coil 3 and the second coil 4. Both ends of the first connecting pipe 8 are connected to the flanges of the two three-way ball valves 9. The second connecting pipe 11 is connected to the flange of the end of the first coil 3, the second coil 4, and the third coil 5 away from the three-way ball valves 9. The first L-shaped gas supply pipe 6 and the second L-shaped gas supply pipe 7 are set up symmetrically in mirror with the first connecting pipe 8 as the center. The first L-shaped gas supply pipe 6 and the second L-shaped gas supply pipe 7 are both connected to the flanges of the three-way ball valves 9.

[0024] A lid 2 is installed on the top surface of the reactor 1, covering the top of the reactor 1 and sealing the internal space of the reactor 1. A temperature sensor 13 is installed on the top surface of the lid 2. The temperature sensor 13 penetrates into the internal space of the reactor 1 to monitor the internal temperature. When the internal temperature of the reactor 1 is low, the temperature sensor 13 processes the collected data through an internal control chip, digitizes it, and transmits it to the display screen on top of the temperature sensor 13, displaying the internal temperature of the reactor 1. The operator uses the temperature displayed by the temperature sensor 13 to determine whether the internal temperature of the reactor 1 needs to be heated. (First coil...) 3. The second coil 4 and the third coil 5 are both wound around the outer surface of the reactor 1, and the top and bottom ends of the first coil 3, the second coil 4, and the third coil 5 are fixed to the outer surface of the reactor 1 by two fixing buckles 10. High-temperature steam is supplied to the first coil 3, the second coil 4, and the third coil 5 to heat them. When the first coil 3, the second coil 4, and the third coil 5 are heated, because they are attached to the outer surface of the reactor 1, the heated first coil 3, the second coil 4, and the third coil 5 heat the reactor 1, thereby increasing the internal temperature of the reactor 1. Since the two coils are perpendicular to each other... The three-way ball valve 9 is connected to the flanges of the first serpentine pipe 3 and the second serpentine pipe 4. Both ends of the first connecting pipe 8 are connected to the flanges of the two three-way ball valves 9, allowing the two three-way ball valves 9 to communicate. This enables the bottom three-way ball valve 9 to deliver steam through the interior of the first connecting pipe 8 into the interior of the top three-way ball valve 9. The top surface of the first L-shaped gas pipe 6 is connected to the bottom flange of the bottom three-way ball valve 9, and the bottom surface of the second L-shaped gas pipe 7 is connected to the top flange of the top three-way ball valve 9. The top surface of the second L-shaped gas pipe 7 is also connected to the flange of the third serpentine pipe 5. This ensures that when steam enters the first L-shaped gas pipe 6, it is first delivered to the bottom three-way ball valve 9. The opening and closing of the third gas passage of the bottom three-way ball valve 9 controls whether steam can pass through the first serpentine pipe 5. A connecting pipe 8 enters the interior of the three-way ball valve 9 at the top, thereby controlling whether steam enters the interior of the second coil 4. When steam enters the three-way ball valve 9 at the top, the opening and closing of the third air passage of the three-way ball valve 9 at the top determines whether steam can enter the second L-shaped gas supply pipe 7, thereby controlling whether steam enters the interior of the third coil 5 connected to the second L-shaped gas supply pipe 7. The second connecting pipe 11 is connected to the flange at the end of the first coil 3, the second coil 4, and the third coil 5 away from the three-way ball valve 9. The steam delivered into the interior of the first coil 3, the second coil 4, and the third coil 5 is heated and then delivered into the interior of the second connecting pipe 11, and is discharged from the second connecting pipe 11 through the air outlet 12 on the surface of the second connecting pipe 11.

[0025] When in use, an external steam source is connected to the first L-shaped gas supply pipe 6, and the steam is delivered through the first L-shaped gas supply pipe 6 to the three-way ball valve 9 connected to the first coiled tube 3. Normally, both three-way ball valves 9 will cut off the third gas passage, only opening the gas passage connected to the first coiled tube 3 and the second coiled tube 4. This allows steam to enter the bottom three-way ball valve 9 and only be delivered into the interior of the first coiled tube 3, heating the bottom of the reactor 1 through the first coiled tube 3. When the reaction volume in the reactor 1 is large, the handle of the three-way ball valve 9 is turned, opening the gas passage connected to the first connecting pipe 8. This allows some steam to enter the first coiled tube 3 after passing through the bottom three-way ball valve 9, while the other part is delivered to the top three-way ball valve 9 through the first connecting pipe 8. Since the top three-way ball valve 9 is connected to the second coiled tube 4, the steam entering the top three-way ball valve 9 is also delivered into the interior of the second coiled tube 4. The steam then passes through the first coiled tube 3 and the second coiled tube 4 to heat the bottom of the reactor 1. The bottom and middle parts of the reactor 1 are heated. When the reaction volume in the reactor 1 is at its maximum, the handle 9 of the three-way ball valve at the top is turned to open the gas passage connected to the second L-shaped gas supply pipe 7. Steam enters the three-way ball valve at the top and then a portion of the steam is diverted into the second L-shaped gas supply pipe 7 at the top. The steam is then transported into the interior of the third coil 5 through the second L-shaped gas supply pipe 7. The bottom, middle and top parts of the reactor 1 are heated simultaneously through the first coil 3, the second coil 4 and the third coil 5. The steam enters different coils to adapt to different reaction volumes inside the reactor 1, which solves the problem of not being able to adjust the length of the coil according to the amount of polyaluminum chloride reacting with wastewater. When the steam enters the first coil 3, the second coil 4 and the third coil 5 and completes the heat transfer, it is discharged through the outlet 12 of the second connecting pipe 11 connected to the right end of the first coil 3, the second coil 4 and the third coil 5. Specific Implementation Example 2:

[0027] Reference Figure 1-4 A polyaluminum chloride reaction temperature adaptive adjustment device, further based on the basic structure in Specific Embodiment 1, can have threaded grooves opened on the surface of the reaction vessel 1 where the first coil 3, the second coil 4, and the third coil 5 are attached. The opened threaded grooves correspond one-to-one with the first coil 3, the second coil 4, and the third coil 5. By embedding the first coil 3, the second coil 4, and the third coil 5 into the opened threaded grooves, the contact area between the first coil 3, the second coil 4, and the third coil 5 and the reaction vessel 1 is increased, thereby increasing the heat transfer effect and reducing heat waste.

[0028] In summary:

[0029] 1. An external steam source is connected to the first L-shaped gas supply pipe 6, and the steam is delivered through the first L-shaped gas supply pipe 6 to the three-way ball valve 9 connected to the first serpentine tube 3. Normally, both three-way ball valves 9 will shut off the third gas passage, only opening the gas passage connected to the first serpentine tube 3 and the second serpentine tube 4. This ensures that steam, after passing through the bottom three-way ball valve 9, is only delivered into the interior of the first serpentine tube 3, heating the bottom of the reactor 1 through the first serpentine tube 3. When the reaction volume in the reactor 1 is large, the handle of the three-way ball valve 9 is turned, opening the gas passage connected to the first connecting pipe 8. This allows some steam to enter the first serpentine tube 3 after passing through the bottom three-way ball valve 9, while the other part is delivered through the first connecting pipe 8 to the top three-way ball valve 9, and then through the top three-way ball valve 9 to the second serpentine tube 4. Inside, the bottom and middle of the reactor 1 are heated by the first coil 3 and the second coil 4. When the reaction volume in the reactor 1 is at its maximum, the handle 9 of the three-way ball valve at the top is turned so that steam passes through the three-way ball valve at the top and then a portion of the steam is diverted into the second L-shaped gas supply pipe 7 at the top. Since the second L-shaped gas supply pipe 7 is connected to the third coil 5, a portion of the steam diverted by the three-way ball valve 9 at the top is transported into the interior of the third coil 5 through the second L-shaped gas supply pipe 7. The bottom, middle and top of the reactor 1 are heated simultaneously by the first coil 3, the second coil 4 and the third coil 5. The steam enters different coils to adapt to different reaction volumes inside the reactor 1, which solves the problem of not being able to adjust the length of the coils according to the amount of polyaluminum chloride reacting with wastewater.
