Abstract
Description
Technical Field
[0001] This application relates to the field of sulfur processing equipment technology, and in particular to a sulfur impurity removal device. Background Technology
[0002] Sulfur, also known as sulfur, colloidal sulfur, or sulfur lumps, appears as pale yellow brittle crystals or powder with a distinctive odor. It is a valuable industrial raw material, used not only in the manufacture of dyes, pesticides, matches, gunpowder, rubber, and rayon, but also as an important type of inorganic pesticide.
[0003] Sulfur inevitably contains some impurities. If these impurities are not removed during production, the quality of subsequent products will be reduced. Current technology typically involves heating the sulfur to obtain a molten mixture of sulfur and impurities. The sulfur is then separated from the impurities based on density differences, thus removing impurities from the sulfur. However, during this process, the poor fluidity of molten sulfur means that impurities are sometimes carried along with the liquid sulfur, affecting the purity of the sulfur. Utility Model Content
[0004] This application provides a sulfur removal device to solve the problems mentioned in the background art.
[0005] This application provides a sulfur removal device, comprising: a box body, a feed inlet at the top of the box body, a light phase outlet and a heavy phase outlet on the side wall of the box body, the light phase outlet being located above the heavy phase outlet, a first valve connected to the light phase outlet, a second valve connected to the heavy phase outlet, and a heating jacket provided outside the box body.
[0006] A servo level gauge is installed on the top of the tank. The servo level gauge is connected to a float via a metering wire. The float is located between the liquid sulfur and the liquid impurities.
[0007] The inner wall of the box is equipped with a first infrared ranging sensor at the outlet of the light phase, and the float is aligned with the first infrared ranging sensor in the vertical direction.
[0008] Optionally, an ultrasonic generator is installed on the inner wall of the chamber.
[0009] Optionally, the heavy phase outlet is located at the inlet end inside the housing, extending vertically downwards into the bottom of the housing.
[0010] Optionally, a second infrared ranging sensor is installed on the inner wall of the box at the same horizontal line as the inlet and outlet of the heavy phase outlet.
[0011] The float is aligned vertically with the first infrared ranging sensor and the second infrared ranging sensor.
[0012] Optionally, the sulfur removal device is also equipped with a controller, which is electrically connected to the first valve, the second valve, the servo level gauge, the first infrared ranging sensor, the ultrasonic generator, and the second infrared ranging sensor.
[0013] Optionally, an insulation layer is also provided outside the heating jacket.
[0014] Optionally, a condenser coil is installed on the top of the enclosure.
[0015] The sulfur removal device provided in this application achieves the separation of sulfur from impurities, and has the following advantages compared with the prior art:
[0016] (1) By setting up a heating jacket, sulfur and impurities are heated to obtain liquid sulfur and liquid impurities, resulting in an upper layer of impurities and a lower layer of sulfur. By setting up a servo level gauge, and the servo level gauge is connected to a float via a metering wire, after settling, the float is located at the interface between the liquid sulfur and the liquid impurities, which can detect the liquid level of sulfur. By setting up a first infrared ranging sensor, the horizontal distance between the first infrared ranging sensor and its opposite sidewall can be detected. When the float moves downward and passes through the light phase outlet, the distance value detected by the first infrared ranging sensor will decrease, the first valve will be opened, and the upper layer of impurities will be discharged. When no liquid flows out of the light phase outlet, the impurities have been discharged. Then the second valve is opened, and the liquid sulfur is discharged through the heavy phase outlet, thus completing the removal of impurities from the sulfur. The sulfur impurity removal device provided in this application, by using a servo level gauge in conjunction with a first infrared ranging sensor, makes the interface control between liquid sulfur and liquid impurities clearer and facilitates the discharge of liquid sulfur and liquid impurities. This avoids the situation in the prior art where the operator does not have a clear understanding of the internal interface, resulting in the liquid sulfur being carried out when discharging impurities, thus avoiding sulfur waste and reducing impurity removal costs.
[0017] (2) By setting up an ultrasonic generator, when the heating jacket heats the sulfur containing impurities in the box, the ultrasonic generator is turned on so that the solid sulfur containing impurities is heated and melted while the ultrasonic waves vibrate and radiate alternately in the solid and liquid sulfur. This is beneficial to reduce the particle size of large solid sulfur containing impurities by vibration, and at the same time, it helps to heat the solid and liquid phases in the sulfur containing impurities evenly, thereby improving the melting efficiency of sulfur and impurities, shortening the impurity removal time, and thus improving the sulfur impurity removal efficiency.
[0018] (3) A controller is set up to open and close the first valve and the second valve according to the signals transmitted by the servo level gauge, the first infrared ranging sensor and the second infrared ranging sensor, and at the same time control the switch of the ultrasonic generator. This setting makes the operation of the sulfur removal device of this application more convenient and accurate, and improves the purity and quality of sulfur. Attached Figure Description

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0026] like Figure 1 As shown, this application provides a sulfur removal device, including: a box body 1, a feed inlet 110 is provided on the top of the box body 1, a light phase outlet 120 and a heavy phase outlet 130 are provided on the side wall of the box body 1, the light phase outlet 120 is located above the heavy phase outlet 130, the light phase outlet 120 is connected to a first valve 121, the heavy phase outlet 130 is connected to a second valve 131, and a heating jacket 2 is provided on the outside of the box body 1.
[0027] A servo level gauge 3 is installed on the top of the housing 1. The servo level gauge 3 is connected to a float 320 via a metering wire 310. The float 320 is located between the liquid sulfur and the liquid impurities.
[0028] The inner wall of the housing 1 is equipped with a first infrared ranging sensor 4 at the light phase outlet 120. The float 320 is aligned with the first infrared ranging sensor 4 in the vertical direction, indicating that the float 320 is located on the infrared light path emitted by the first infrared ranging sensor 4 in the horizontal direction.
[0029] Specifically, sulfur contains some impurities, which need to be separated from the sulfur before use. A feed inlet 110 is provided at the top of the tank 1 for feeding the sulfur to be purified into the tank 1. A heating jacket 2 is provided on the outside of the tank 1 to heat the sulfur containing impurities to a molten state. Since the molten impurities and sulfur have different densities, the molten sulfur and impurities are separated into layers by settling, with the impurities being the lighter phase and the sulfur the heavier phase, resulting in a layered state of impurities on top and sulfur on the bottom. A servo level gauge 3 can detect the sulfur level. When the sulfur containing impurities is heated to melt and then allowed to settle, the density of the float 320 is greater than the density of the molten impurities and close to the density of the molten sulfur. Therefore, after settling, the float 320 can be located between the liquid sulfur and the liquid impurities, i.e., at the interface between the liquid sulfur and the liquid impurities.
[0030] After settling, the light phase impurities and heavy phase sulfur need to be discharged. In specific operation, first, open the second valve 131 and discharge the heavy phase sulfur to the sulfur collection tank 132 through the heavy phase outlet 130. During the process, the liquid level of sulfur drops, which in turn causes the interface between liquid sulfur and liquid impurities to drop, that is, the float 320 is displaced downward. As the float 320 moves downward, it passes through the light phase outlet 120. The first infrared ranging sensor 4 can detect the horizontal distance between the first infrared ranging sensor 4 and its opposite sidewall. Since the float 320 and the first infrared ranging sensor 4 are aligned vertically, when the float 320 passes through the light phase outlet 120, the distance detected by the first infrared ranging sensor 4 will decrease to a preset value (i.e., the distance between the float 320 and the first infrared ranging sensor 4). This indicates that the interface between the liquid sulfur and the liquid impurities is located at the light phase outlet 120. At this time, the first valve 121 is opened, and the molten impurities in the upper layer are discharged to the impurity collection box 122 through the light phase outlet 120. When no liquid flows out of the light phase outlet 120, the impurities have been discharged.
[0031] Close the first valve 121 and open the second valve 131 to discharge the heavy phase liquid sulfur into the sulfur collection tank 132 through the heavy phase outlet 130. When there is no liquid outflow from the heavy phase outlet 130 and / or the liquid level value of the servo level gauge 3 does not change, the sulfur discharge is complete, and the removal of impurities from the sulfur is finished.
[0032] This application achieves the purpose of removing impurities from sulfur through the above-described scheme. By setting up a heating jacket, sulfur and impurities are heated to form liquid sulfur and liquid impurities, which are then allowed to settle and separate into layers, resulting in an upper layer of impurities and a lower layer of sulfur. By setting up a servo level gauge connected to a float via a metering wire, the float is positioned at the interface between the liquid sulfur and liquid impurities after settling, allowing for the detection of the sulfur level. By setting up a first infrared ranging sensor, the horizontal distance between the first infrared ranging sensor and its opposite sidewall can be detected. As the float moves downwards and passes the light phase outlet, the distance value detected by the first infrared ranging sensor decreases, indicating that the interface between the liquid sulfur and liquid impurities is at the light phase outlet. The first valve is then opened to discharge the upper layer of impurities. When no liquid flows out of the light phase outlet, the impurities have been completely discharged. Then, the second valve is opened to discharge the liquid sulfur through the heavy phase outlet, completing the removal of impurities from the sulfur. The sulfur impurity removal device provided in this application, by using a servo level gauge in conjunction with a first infrared ranging sensor, makes the interface control between liquid sulfur and liquid impurities clearer and facilitates the discharge of liquid sulfur and liquid impurities. This avoids the situation in the prior art where the operator does not have a clear understanding of the internal interface, resulting in the liquid sulfur being carried out when discharging impurities, thus avoiding sulfur waste and reducing impurity removal costs.
[0033] like Figure 2 As shown, optionally, an ultrasonic generator 5 is installed on the inner wall of the housing 1.
[0034] Specifically, when heating the sulfur containing impurities in the chamber 1 through the heating jacket 2, the ultrasonic generator 5 is turned on, so that the solid sulfur containing impurities is heated and melted while the ultrasonic waves vibrate and radiate alternately in the solid and liquid sulfur. This helps to reduce the particle size of large solid sulfur containing impurities and also helps to heat the solid and liquid phases in the sulfur containing impurities evenly, thereby improving the melting efficiency of sulfur and impurities and shortening the impurity removal time.
[0035] Optionally, the heavy phase outlet 130 is located inside the tank 1, extending vertically downwards into the bottom of the tank 1 from the inlet end. This arrangement allows for the discharge of liquid sulfur as much as possible while reducing the content of impurities in the sulfur, thereby improving the quality of the sulfur.
[0036] like Figure 2 As shown, optionally, a second infrared ranging sensor 7 is provided on the inner wall of the housing 1 at the same horizontal line as the inlet end of the heavy phase outlet 130.
[0037] The float 320 is vertically aligned with the first infrared ranging sensor 4 and the second infrared ranging sensor 7. This means that when the float 320 descends to the same horizontal height as the first infrared ranging sensor 4 and the second infrared ranging sensor 7, the float 320 can be located on the path of the infrared light emitted horizontally by the first infrared ranging sensor 4 and the second infrared ranging sensor 7, so that the first infrared ranging sensor 4 and the second infrared ranging sensor 7 can detect the horizontal distance between the float 320 and the first infrared ranging sensor 4 and the second infrared ranging sensor 7.
[0038] Specifically, after the impurities are discharged, the first valve 121 is closed and the second valve 131 is opened, allowing the heavy phase liquid sulfur to be discharged into the sulfur collection tank 132 through the heavy phase outlet 130. During the liquid sulfur discharge process, the interface moves downward, i.e., the float 320 moves downward. When the distance value detected by the second infrared ranging sensor 7 is a preset value (i.e., the horizontal distance between the float 320 and the first infrared ranging sensor 4 / second infrared ranging sensor 7), it indicates that the sulfur discharge is complete, and the impurity removal of the sulfur is finished. This setting makes the detection and control of the interface more convenient, thereby enabling accurate discharge of impurities and sulfur, and improving the purity of the sulfur.
[0039] like Figure 3 As shown, optionally, the sulfur removal device is also equipped with a controller 6, which is electrically connected to the first valve 121, the second valve 131, the servo level gauge 3, the first infrared ranging sensor 4, the ultrasonic generator 5 and the second infrared ranging sensor 7 respectively.
[0040] Specifically, the controller 6 is used to open and close the first valve 121 and the second valve 131 according to the signals transmitted by the servo level gauge 3, the first infrared ranging sensor 4, and the second infrared ranging sensor 7, and at the same time control the switch of the ultrasonic generator 5.
[0041] like Figure 2 As shown, optionally, an insulation layer 8 is also provided outside the heating jacket 2.
[0042] Specifically, the insulation layer 8 is used to keep the temperature inside the box 1 in order to maintain the heating efficiency of the sulfur inside the box 1 and avoid heat waste.
[0043] like Figure 2 As shown, optionally, a condenser pipe 9 is installed on the top of the housing 1.
[0044] Specifically, during the heating process of the sulfur containing impurities in the chamber 1, a small amount of sulfur-containing gas is generated. Circulating water is introduced into the condenser pipe 9 as a cooling medium to condense the gas that escapes during the heating process. The small amount of sulfur vapor contained therein is condensed and returned to the chamber 1, further avoiding the waste of sulfur.
[0045] The technical solution of this application will be illustrated in detail below with specific embodiments.
[0046] The sulfur removal device in this embodiment operates as follows:
[0047] Sulfur to be purified is fed into the chamber 1 through the feed inlet 110. A heating jacket 2 is installed on the outside of the chamber 1 to heat the sulfur containing impurities to a molten state. Simultaneously, the controller 6 activates the ultrasonic generator 5. Since the molten impurities and sulfur have different densities, the molten sulfur and impurities are separated into layers by settling, with the impurities being the lighter phase and the sulfur the heavier phase, resulting in an upper layer of impurities and a lower layer of sulfur. During the heating and melting process of the sulfur containing impurities, the interface between the liquid sulfur and liquid impurities is unstable, therefore the liquid level value transmitted from the servo level gauge 3 to the controller 6 is also unstable. The setpoint is established that if the error in the liquid level value received by the controller 6 from the servo level gauge 3 is within a preset error range (0.5-0.8) within a certain time period (e.g., 5-10 minutes) during the layering process, the settling process is considered complete. The controller 6 then shuts off the ultrasonic generator 5.
[0048] First, controller 6 opens the second valve 131, discharging the heavy phase sulfur through the heavy phase outlet 130 into the sulfur collection tank 132. During this process, the sulfur level drops, causing the interface between the liquid sulfur and liquid impurities to drop, i.e., the float 320 displaces downward. As the float 320 moves downward, it passes through the light phase outlet 120. The first infrared ranging sensor 4 transmits the horizontal distance detected by the first infrared ranging sensor 4 to its opposite sidewall to controller 6. When the float 320 passes through the light phase outlet 120, the distance detected by the first infrared ranging sensor 4 decreases to a preset value (i.e., the distance between the float 320 and the first infrared ranging sensor 4), indicating that the interface between the liquid sulfur and liquid impurities is located at the light phase outlet 120. At this time, controller 6 opens the first valve 121, discharging the upper molten impurities through the light phase outlet 120 into the impurity collection tank 122. When no liquid flows out of the light phase outlet 120, the impurities have been completely discharged.
[0049] The controller 6 closes the first valve 121 and simultaneously opens the second valve 131, discharging the heavy phase liquid sulfur through the heavy phase outlet 130 into the sulfur collection tank 132. During the liquid sulfur discharge process, the float 320 moves downward. When the controller 6 receives a distance value transmitted from the second infrared ranging sensor 7 that is the preset value (i.e., the horizontal distance between the float 320 and the first infrared ranging sensor 4 / second infrared ranging sensor 7), or when the liquid level signal received by the controller 6 from the servo level gauge 3 does not change within a certain time (5-15 minutes), it indicates that the sulfur discharge is complete. The controller 6 then closes the second valve 131, completing the removal of impurities from the sulfur.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
