Abstract
Description
Technical Field
[0001] This application relates to polysilicon industrial technology, and more particularly to a level gauge. Background Technology
[0002] The polycrystalline silicon cold hydrogenation process mainly involves a hydrogenation reaction in a fluidized bed hydrogenation reactor under the conditions of hydrogen and silicon tetrachloride at 565-590℃ / 2.5-2.9 MPa, with copper chloride as a catalyst. The chlorosilane and hydrogen mixture exiting the reactor contains high-boiling-point chlorosilanes, metal chlorides, and trace amounts of fine silicon powder. After being cooled and washed by a quench tower, the residual fine silicon powder, high-boiling-point chlorosilanes, and metal chlorides gradually crystallize and precipitate in the quench tower bottom and are discharged into a slurry collection tank. To monitor the liquid level in the slurry collection tank, a magnetic level gauge is usually connected externally to one side of the tank. During use, the residual fine silicon powder, high-boiling-point chlorosilanes, and metal chlorides crystallize and precipitate on the float of the magnetic level gauge, causing blockage and malfunction.
[0003] Existing technologies mainly employ spray washing and electric heating. Spray washing removes precipitates from the surface of the float body, while electric heating is used to heat the level gauge body to suppress crystallization on the surface of the float body. However, the magnetic field generated during the use of electric heating can easily demagnetize the float body, leading to the failure of the magnetic level gauge. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0043] First, let me explain the terms used in this application:
[0044] Magnetic float level gauge: Based on the principle of communicating vessels, it was developed using the principles of buoyancy and magnetic coupling. When the liquid level in the container being measured rises or falls, the permanent magnet inside the float transmits the signal to the magnetic float indicator panel through magnetic coupling, causing the red and white floats to rotate 180°. When the liquid level rises, the float changes from white to red; when the liquid level falls, the float changes from red to white. The boundary between the red and white areas on the panel indicates the actual height of the liquid level in the container, thus achieving liquid level display.
[0045] Pump: A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.
[0046] Crystallization: Crystallization refers to the process by which a solute spontaneously precipitates from a supersaturated solution to form a new phase. When the concentration of a solution equals the solubility of the solute, the solution is called a saturated solution. When the concentration of the solute exceeds its solubility, the solution is called a supersaturated solution. Precipitation of the solute can only occur in supersaturated solutions. In most cases, solubility is temperature-dependent; generally, substances precipitate as the temperature decreases.
[0047] The polycrystalline silicon cold hydrogenation process mainly involves hydrogen and silicon tetrachloride at 565-590℃ / 2.5-2.9 MPa, with copper chloride as a catalyst, in a fluidized bed hydrogenation reactor to produce a mixture of chlorosilanes such as trichlorosilane, silicon tetrachloride, and dichlorosilane. The chlorosilane and hydrogen mixture coming out of the reactor contains high-boiling-point chlorosilanes, metal chlorides, and trace amounts of fine silica powder. After being sprayed and cooled by the quench tower, the residual fine silica powder, high-boiling-point chlorosilanes, and metal chlorides gradually crystallize and precipitate in the bottom of the quench tower and are discharged into the slurry collection tank. In order to monitor the liquid level in the slurry collection tank, a magnetic float level gauge is usually connected to one side of the slurry collection tank. During the use of the magnetic float level gauge, the residual fine silica powder, high-boiling-point chlorosilanes, and metal chlorides will crystallize and precipitate on the float body 220 of the magnetic float level gauge, which will cause blockage of the level gauge and cause the magnetic float level gauge to fail.
[0048] Existing technologies mainly employ spray washing and electric heating. The float body 220 is sprayed to remove the precipitates on its surface, while the level gauge body 100 is heated by electric heating to suppress crystallization on the surface of the float body 220. However, the magnetic field generated during the use of electric heating can easily cause the float to demagnetize, leading to the failure of the magnetic level gauge.
[0049] To address the aforementioned technical problems, the liquid level gauge provided in this application includes a liquid level gauge body 100, a float assembly 200, a display assembly 300, and a heating assembly 400. The heating assembly 400 is adapted to be connected to the outer surface of the liquid level gauge body 100. The heating assembly 400 heats the liquid level gauge body 100 with steam. In this application, the liquid level gauge body 100 is heated by steam, thereby avoiding the problem in related technologies where electric heat tracing can easily cause the float assembly 200 to demagnetize.
[0050] like Figure 1 As shown, this embodiment provides a level gauge, including a level gauge body 100, a float assembly 200, and a heating assembly 400. One side of the level gauge body 100 is adapted to communicate with a slurry collection tank. The float assembly 200 is disposed inside the level gauge body 100 and moves up and down as the liquid level inside the level gauge body 100 changes. The heating assembly 400 is adapted to be connected to the outer surface of the level gauge body 100 and uses steam flowing through a heat-conducting pipe 420 to heat the level gauge body 100.
[0051] In this embodiment, the heating component 400 heats the liquid, causing it to vaporize into steam. The steam then contacts the level gauge body 100 and exchanges heat, raising the temperature of the level gauge body 100. This suppresses crystallization on the float assembly 200, ensuring the normal operation of the float assembly 200. Furthermore, the steam heating method does not cause the float assembly 200 to demagnetize, ensuring the normal operation of the level gauge structure.
[0052] It should be noted that, in this embodiment, a display component 300 is also included, wherein the display component 300 is disposed on the level gauge body 100; the display component 300 displays the liquid level position inside the level gauge body 100 according to the position of the float component 200; the display component 300 is composed of a flap box and red and white dual-color magnetic flaps, wherein the display component 300 extends along the extension direction of the level gauge body 100, the display component 300 is disposed on the outer surface of the level gauge body 100, and the position of the liquid level inside the level gauge is displayed through the dividing line of the red and white magnetic flaps.
[0053] Furthermore, this embodiment provides a level gauge, wherein the heating assembly 400 includes a heating part 410 and a heat-conducting pipe 420; wherein the heating part 410 is adapted to heat the liquid and generate steam; wherein the heating pipe is adapted to communicate with the heating part 410 and is adapted to allow steam to flow through; the heat-conducting pipe 420 is connected to the outer surface of the level gauge body 100; the heat-conducting pipe 420 is adapted to heat the level gauge body 100.
[0054] In this embodiment, the liquid is heated by the heating unit 410. After absorbing heat, part of the liquid will turn into high-temperature steam. The high-temperature steam enters the heat conduction pipe 420 and heats the heat conduction pipe 420. The heat conduction pipe 420 exchanges heat with the liquid level gauge body 100 through direct contact and heats the liquid level gauge body 100. The heating method of high-temperature steam does not generate a magnetic field, so it will not cause the float assembly 200 to be demagnetized, thereby ensuring the normal use of the float assembly 200.
[0055] As an alternative implementation, the interior of the heating unit 410 can heat the liquid by combustion heating. In this embodiment, the interior of the heating unit 410 uses electric heating. Electric heating, by heating metal materials, has the advantages of being the most efficient, the fastest, and having low energy consumption and environmental friendliness.
[0056] Furthermore, this embodiment provides a level gauge in which the heating pipe is serpentinely wound around the outer surface of the level gauge body 100. The heating pipe is connected to the level gauge body 100 by winding, which can further increase the heat exchange efficiency between the heating pipe and the level gauge body 100. It should be noted that increasing the number of turns of the heating pipe can further increase the contact area between the heating pipe and the level gauge body 100, thereby further improving the heat exchange efficiency between the heating pipe and the level gauge body 100.
[0057] It should be noted that the level gauge body 100 is connected to the slurry collection tank through two connecting pipes. The connecting pipe at the bottom facilitates the entry of liquid from the slurry collection tank into the level gauge body 100. When the connecting pipe at the top is in place, the air pressure at the top of the level gauge body 100 is the same as the pressure inside the slurry collection tank. The heating pipe is also wrapped around the outer surface of the connecting pipe at the bottom, thereby increasing the temperature of the liquid entering the level gauge body 100.
[0058] Furthermore, this embodiment provides a level gauge, which also includes a circulation component 500. The circulation component 500 is adapted to communicate with the level gauge body 100 and the heating component 400. The circulation component 500 is adapted to collect the liquid in the level gauge body 100 and transport it to the heating component 400. The liquid in the level gauge body 100 is transported to the heating unit 410 through the circulation component 500 and heated by the heating unit 410. By providing the circulation component 500, a continuous supply of liquid can be provided to the heating component 400 for heating.
[0059] Furthermore, this embodiment provides a level gauge, wherein the circulation assembly 500 includes a condensate collector 510, a circulation pipeline 520, and a circulation pump 530. The condensate collector 510 is disposed at the bottom of the level gauge body 100; the condensate collector 510 is adapted to collect liquid within the level gauge body 100; the first end of the circulation pipeline 520 is adapted to communicate with the condensate collector 510, and the second end of the circulation pipeline 520 is adapted to communicate with the heating assembly 400; the circulation pump 530 is disposed on the circulation pipeline 520; the circulation pump 530 is adapted to drive the liquid within the circulation pipeline 520 to move from the condensate collector 510 toward the heating assembly 400. Specifically, the liquid flows into the condensate collector 510 under the action of gravity, and then the liquid within the condensate collector 510 moves along the circulation pipeline 520 toward the heating assembly 400 under the drive of the circulation pump 530, thereby providing liquid to the heating assembly 400.
[0060] In this embodiment, the condensate collection device 510 is a box structure, and the interior of the condensate collection device 510 has a certain capacity, the size of which can be adjusted as needed.
[0061] Specifically, during use, residual silicon powder, high-boiling-point chlorosilanes, and metal chlorides will also enter the level gauge body 100 along with the liquid, which will cause blockage of the level gauge body 100 over time. By setting a condensate collection device 510 at the bottom of the level gauge body 100, the residual silicon powder, high-boiling-point chlorosilanes, and metal chlorides will collect in the condensate collection device 510 under the action of gravity. At this time, it is only necessary to clean the condensate collection device 510 regularly to prevent the problem of residual silicon powder, high-boiling-point chlorosilanes, and metal chlorides clogging the level gauge body 100.
[0062] It should be noted that the connections at both ends of the circulation pipeline 520 should pass an airtightness test to ensure the service life of the overall structure. The circulation pump 530 is a common water pump available on the market, and its power can be adjusted according to the output efficiency of the heating unit 410.
[0063] Furthermore, this embodiment provides a level gauge, which also includes a spray assembly 600, disposed on one side of the heating assembly 400; the spray assembly 600 is adapted to receive the liquid discharged from the heating assembly 400; the spray assembly 600 is adapted to spray the float assembly 200. By spraying liquid onto the float assembly 200 through the spray assembly 600, the crystals precipitated on the surface of the float assembly 200 can be washed away, preventing the crystals from accumulating on the surface of the float assembly 200 and thus clogging the level gauge body 100. It should be noted that the crystals will precipitate on the surface of the float assembly 200, and after a long period of precipitation, the float assembly 200 will become larger and larger and eventually clog the level gauge body 100. However, the newly precipitated crystals have low adsorption on the surface of the float assembly 200 and can be washed away by simple spraying. By continuously spraying the surface of the float assembly 200, the cleanliness of the surface of the float assembly 200 can be maintained.
[0064] Specifically, this embodiment provides a level gauge, wherein the spray assembly 600 includes a collecting part 610 and a spraying part 620, wherein the collecting part 610 is funnel-shaped; the collecting part 610 is disposed on one side of the heating assembly 400 and communicates with the heating assembly 400; the collecting part 610 is adapted to receive the liquid discharged from the heating assembly 400; wherein the spraying part 620 communicates with the collecting part 610; a plurality of spray holes are formed on the spraying part 620; the liquid is sprayed onto the float assembly 200 through the spray holes. By forming spray holes on the spraying part 620, the spray float assembly 200 is realized, wherein the spraying effect can be adjusted by controlling the size and spacing of the spray holes, which has the advantages of low manufacturing cost and controllable spraying effect.
[0065] It should be noted that the liquid in the spray section 620 is also a high-temperature liquid under the action of the heating section 410. The high-temperature liquid also heats the float assembly 200 in a relative way through the spray section 620, suppressing the crystal precipitation on the float assembly 200.
[0066] It is understood that the collecting part 610 is located on the lower side of the heating component 400. After the liquid in the heating component 400 is heated, it moves towards the collecting part 610 under the action of gravity. The collecting part 610 is funnel-shaped with a large opening at the top and a small opening at the bottom. Designing the collecting part 610 as a funnel ensures that all the liquid flowing out of the heating component 400 is collected. In order to ensure that the float assembly 200 is completely sprayed, the bottom area of the spraying part 620 can be increased. In this embodiment, the bottom area of the spraying part 620 is the same as the cross-sectional area of the level gauge body 100. The top of the spraying part 620 is connected to the collecting part 610 through a pipe. The liquid in the collecting part 610 enters the spraying part 620 through the pipe, and then the liquid sprays the float assembly 200 through the spray holes under the action of gravity.
[0067] It should be noted that, in order to further enhance the spraying effect, a pressurization structure can be added to increase the pressure inside the spray section 620, thereby increasing the scouring force of the liquid on the surface of the float assembly 200 and making the surface of the float assembly 200 cleaner.
[0068] Furthermore, this embodiment provides a level gauge, wherein the float assembly 200 includes a connecting rod 210 and a float body 220; wherein the connecting rod 210 is disposed inside the level gauge body 100; the extending direction of the connecting rod 210 is arranged along the length direction of the level gauge body 100; the float body 220 is slidably connected to the connecting rod 210; the float body 220 moves along the extending direction of the connecting rod 210 along the liquid level height inside the level gauge body 100.
[0069] Understandably, within the level gauge body 100, the float body 220, under the spraying action of the spray assembly 600, will move irregularly in the horizontal direction. During this movement, the magnetic flap may flip inaccurately, leading to inaccurate level data. By slidingly connecting the float body 220 to the connecting rod 210, when the liquid level rises, the float body 220 rises along the extension direction of the connecting rod 210; when the liquid level falls, the float body 220 falls along the extension direction of the connecting rod 210. Because the float body 220 is connected to the connecting rod 210, during the spraying process by the spray assembly 600, the float body 220 will not move irregularly in the horizontal direction, increasing its stability.
[0070] It should be noted that in this embodiment, the connecting rod 210 is located at the central axis of the liquid level gauge body 100. The connecting rod 210 can be fixedly connected to the liquid level gauge body 100 through other connecting parts, such as other connecting parts. The two ends of the connecting parts are fixedly connected to the liquid level gauge body 100 and the connecting rod 210 respectively, thereby realizing that the connecting rod 210 is located inside the liquid level gauge body 100 and fixedly connected to the liquid level gauge body 100.
[0071] Specifically, the float body 220 has a sliding hole inside, and the connecting rod 210 is adapted to pass through the sliding hole; the float body 220 is slidably connected to the connecting rod 210 through the sliding hole; the hole and shaft connection has the advantages of structural stability, high positioning accuracy, easy disassembly and maintenance, wide applicability, and improved mechanical system performance.
[0072] It should be noted that in this embodiment, the connecting rod 210 and the sliding hole are in clearance fit. The clearance fit can minimize the friction between the connecting rod 210 and the sliding hole, thereby ensuring the sensitivity of the float body 220 in moving on the connecting rod 210.
[0073] Furthermore, this embodiment provides a level gauge, which also includes a first flange 700. The first flange 700 is disposed between the level gauge body 100 and the condensate collection component 510. The level gauge body 100 is connected to the condensate collection component 510 through the first flange 700. It has the advantages of easy disassembly for equipment maintenance and repair, good sealing performance, suitability for high pressure and high temperature environments, reduced leakage risk, wide applicability, and can be used for various pipeline and equipment connections, as well as high strength.
[0074] It should be noted that a second flange 800 is provided between the level gauge body 100 and the slurry collection tank. Connecting the level gauge body 100 and the slurry collection tank through the second flange 800 has the advantages of easy disassembly for equipment maintenance and repair, good sealing performance, suitability for high pressure and high temperature environments, reduced leakage risk, wide applicability, and can be used for various pipeline and equipment connections, as well as high strength.
[0075] It should be noted that, in order to protect the safety of the heat conduction pipe 420, an outer shell is also provided on the outside of the heat conduction pipe 420. The outer shell is fitted on the outer surface of the heat conduction pipe 420 to prevent external factors from damaging the heat conduction pipe 420. In addition, the outer shell can also play a role in heat preservation and increase the heat exchange effect between the heat conduction pipe 420 and the liquid level gauge body 100.
