Description

Technical Field

[0001] This utility model relates to the field of condensation device technology, and in particular to a gradient condenser collector for arsenic and antimony separation. Background Technology

[0002] In the field of non-ferrous metal smelting and resource recycling, arsenic and antimony are important metallic elements that often coexist. Efficient separation of them has important economic value and environmental significance. Since the saturated vapor pressure of arsenic is higher than that of antimony, arsenic will vaporize and separate first. In the process of condensing and collecting arsenic, a condenser is required.

[0003] Currently, most existing condenser collectors achieve their effects using the following technologies;

[0004] Heat exchange technology: Indirect heat exchange separates steam and cooling medium through metal walls to achieve condensation, which can ensure product purity; Mixed heat exchange allows the two to come into direct contact, resulting in high heat transfer efficiency, but may introduce impurities.

[0005] Temperature control technology: The condensation temperature is controlled by adjusting the flow rate of the cooling medium, or multi-stage cooling is used to gradually cool the steam by utilizing different temperature zones to achieve precise condensation and collection;

[0006] Gas-liquid separation technology: Gravity sedimentation allows the coolant to sink naturally; cyclone separation uses centrifugal force to throw droplets toward the container wall; filtration separation uses porous media or filter screens to trap the coolant and achieve gas-liquid separation.

[0007] Currently, existing condensate collectors have been found to have at least the following technical problems in practical use;

[0008] Most existing condenser collectors for arsenic condensation have detachable condenser tubes, which facilitate maintenance and replacement. However, the connection between the condenser tube and the condenser chamber is mostly just a threaded connection without a sufficiently tight sealing mechanism, which can easily lead to coolant leakage. Utility Model Content

[0009] To address the shortcomings of existing technologies, this invention provides a gradient condenser collector for arsenic and antimony separation, solving the problem of coolant leakage in the condenser tubes of existing condenser collectors.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A gradient condenser collector for arsenic and antimony separation includes a condensation chamber and a sealing cover. The condensation chamber is flange-connected to the sealing cover, and a feed pipe is fixedly connected to the sealing cover. A metal connecting sleeve is fixedly connected to one end of the feed pipe near the condensation chamber. A condensation assembly is provided inside the condensation chamber, and a sealing mechanism is provided between the condensation assembly and the condensation chamber. The assembly includes a condensation pipe, a through hole, and a connecting flange. The sealing mechanism includes a docking flange, a support plate, and a metal sealing sleeve.

[0012] Preferably, the surface of the condensation chamber is fixedly connected to an inlet pipe and an outlet pipe, the bottom of the condensation chamber is funnel-shaped, and the bottom surface of the condensation chamber is fixedly connected to a discharge pipe.

[0013] Preferably, the mating flange is annular, and the mating flange is fixedly connected to the top of the inner wall of the condensing chamber, while the support plate is fixedly connected to the bottom of the inner wall of the condensing chamber.

[0014] Preferably, both the support plate and the metal sealing sleeve are annular, the metal sealing sleeve is fixedly connected to the top surface of the support plate, and an annular groove is formed on the top surface of the metal sealing sleeve.

[0015] Preferably, through holes are formed on the surface of the condenser tube, and multiple through holes are formed, with a connecting flange fixedly connected to the top of the condenser tube.

[0016] Preferred configuration: The connecting flange and the mating flange are in contact. Both the connecting flange and the mating flange have six threaded holes on their surfaces. The threaded holes of the connecting flange are through holes, while the threaded holes of the mating flange are semi-grooved. The twelve threaded holes are adapted to six hexagonal bolts. The top surface of the mating flange has an annular sealing groove, and the bottom surface of the connecting flange is fixedly connected to an annular sealing ring. The annular sealing ring is adapted to the annular sealing groove.

[0017] Preferably, the end of the condenser tube furthest from the connecting flange is inserted into the inner side of the annular groove on the top surface of the metal sealing sleeve, and there is an interference fit between the condenser tube and the metal sealing sleeve.

[0018] Preferably, the top surface of the condenser tube is fitted with the metal connecting sleeve, and there is an interference fit between the condenser tube and the metal connecting sleeve.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The bottom of the condenser tube is press-fitted with the metal sealing sleeve. For the coolant to pass through the metal sealing sleeve and enter the inside of the condenser tube, it needs to pass through two bends. Furthermore, the press-fit between the condenser tube and the metal sealing sleeve makes it extremely difficult for liquid to penetrate, ultimately achieving a tight seal. The top of the condenser tube is detachably connected to the connecting flange and the mating flange via a connecting flange. A sealing gasket is placed between the connecting flange and the mating flange, further increasing the tightness and giving this application a high sealing effect. The condenser tube is fitted with the metal sealing sleeve, and the mating flange and connecting flange can also be separated by removing the hexagonal bolts. The sealing cover and the condenser chamber can also be separated. This allows this application to achieve a high sealing effect while also allowing for condenser tube replacement, solving the problem of coolant leakage that easily occurs in existing condenser collectors.

[0021] Second, when the gas enters the condenser tube through the feed pipe, the structure is disrupted by the various through holes in the condenser tube, which makes the contact between the gas and the condenser tube more complete. At the same time, the various through holes can also increase the contact area between the condenser tube and the coolant, increase the heat exchange efficiency, and make it have a high cooling efficiency.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem of coolant leakage in existing condenser collector condenser tubes. The overall idea is as follows:

[0032] To address the problems existing in the prior art, this utility model provides a gradient condenser collector for arsenic and antimony separation, including a condensation chamber 1 and a sealing cover 2. The condensation chamber 1 is flange-connected to the sealing cover 2, and a feed pipe 201 is fixedly connected to the sealing cover 2. A metal connecting sleeve 202 is fixedly connected to one end of the feed pipe 201 near the condensation chamber 1. A condensation assembly is provided inside the condensation chamber 1, and a sealing mechanism is provided between the condensation assembly and the condensation chamber 1. The assembly includes a condensation pipe 3, a through hole 301, and a connecting flange 302. The sealing mechanism includes a docking flange 104, a support plate 105, and a metal sealing sleeve 106.

[0033] The surface of the condensation chamber 1 is fixedly connected with an inlet pipe 101 and an outlet pipe 102. The bottom of the condensation chamber 1 is funnel-shaped, and the bottom surface of the condensation chamber 1 is fixedly connected with a discharge pipe 103.

[0034] The mating flange 104 is annular and is fixedly connected to the top of the inner wall of the condensing chamber 1. The support plate 105 is fixedly connected to the bottom of the inner wall of the condensing chamber 1.

[0035] Both the support plate 105 and the metal sealing sleeve 106 are annular. The metal sealing sleeve 106 is fixedly connected to the top surface of the support plate 105, and an annular groove is provided on the top surface of the metal sealing sleeve 106.

[0036] Multiple through holes 301 are provided on the surface of the condenser tube 3, and the connecting flange 302 is fixedly connected to the top of the condenser tube 3.

[0037] The connecting flange 302 contacts the mating flange 104. Both the connecting flange 302 and the mating flange 104 have six threaded holes on their surfaces. The threaded holes of the connecting flange 302 are through holes, while the threaded holes of the mating flange 104 are semi-grooved holes. The twelve threaded holes are fitted with six hexagonal bolts. The top surface of the mating flange 104 has an annular sealing groove, and the bottom surface of the connecting flange 302 is fixedly connected with an annular sealing ring, which is compatible with the annular sealing groove.

[0038] The end of the condenser tube 3 away from the connecting flange 302 is inserted into the inner side of the annular groove opened on the top surface of the metal sealing sleeve 106, and there is an interference fit between the condenser tube 3 and the metal sealing sleeve 106.

[0039] The top surface of the condenser tube 3 is fitted with the metal connecting sleeve 202, and there is an interference fit between the condenser tube 3 and the metal connecting sleeve 202.

[0040] Condensation chamber 1: As the main structure of the entire condenser, it provides space for coolant and condensation process. Its funnel-shaped bottom design facilitates the collection of arsenic after condensation. Coolant circulation is achieved through inlet pipe 101 and outlet pipe 102, and discharge pipe 103 is used to discharge arsenic after condensation.

[0041] Sealing cover 2: It is connected to the condensation chamber 1 via a flange and serves as a seal. The feed pipe 201, which is fixedly connected, is used to introduce gaseous arsenic raw materials.

[0042] Condenser 3: This is the main place for the condensation of gaseous arsenic raw material. The gaseous arsenic exchanges heat with the coolant in it to achieve condensation. The through holes 301 on the surface can disrupt the gas flow structure, increase the contact area between the gas and coolant and condenser 3, and improve the cooling efficiency.

[0043] Liquid inlet pipe 101: Installed on the surface of condenser 1, used to pump coolant into the inside of condenser 1.

[0044] Liquid outlet pipe 102: Installed on the surface of condenser 1, used for coolant discharge and circulation.

[0045] Discharge pipe 103: Installed on the bottom of condensation chamber 1, used to discharge the condensed arsenic to the collection device.

[0046] The mating flange 104 is fixed to the top of the inner wall of the condensing chamber 1 and is connected to the connecting flange 302 by hexagonal bolts. The annular sealing groove on the top surface cooperates with the annular sealing ring on the bottom surface of the connecting flange 302 to enhance the sealing performance of the top connection of the condensing pipe 3.

[0047] Support plate 105: Fixed to the bottom of the inner wall of the condensation chamber 1, providing support for the metal sealing sleeve 106.

[0048] Metal sealing sleeve 106: fixed on the top surface of support plate 105, its top annular groove is interference fit with the bottom of condenser tube 3 to achieve sealing of the bottom of condenser tube 3.

[0049] Feed pipe 201: Fixed on the sealing cover 2, connected to the external feed pump, used to introduce gaseous arsenic raw material.

[0050] Metal connecting sleeve 202: It is fixed at one end of the feed pipe 201 near the condensation chamber 1 and is sleeved with the top of the condensation pipe 3 to facilitate the entry of gaseous arsenic raw material into the condensation pipe 3.

[0051] Through holes 301: These are formed on the surface of the condenser tube 3. There are multiple through holes, which can disrupt the gas flow structure and increase the contact area to improve cooling efficiency.

[0052] Connection flange 302: Fixed to the top of condenser tube 3, and cooperates with mating flange 104 to achieve connection and sealing of the top of condenser tube 3.

[0053] Working principle:

[0054] In the first step, this application connects the feed pipe 201 to an external feed pump, and the liquid inlet pipe 101 connects to the discharge pipe 103 and an external condenser. Coolant is pumped into the inner side of the condensation chamber 1 through the liquid inlet pipe 101 and discharged through the liquid outlet pipe 102. The gaseous arsenic raw material introduced by the feed pipe 201 enters the inner side of the condenser pipe 3 through the metal connecting sleeve 202. During the flow inside the condenser pipe 3, it will exchange heat with the coolant through the condenser pipe 3 to achieve the condensation effect. Finally, it falls into the bottom of the condensation chamber 1 through the condenser pipe 3 and is discharged to the collection device through the discharge pipe 103.

[0055] In the second step, the bottom of the condenser tube 3 is press-fitted with the metal sealing sleeve 106. The coolant needs to go through two bends to pass through the metal sealing sleeve 106 and enter the inside of the condenser tube 3. The press-fit between the condenser tube 3 and the metal sealing sleeve 106 makes it extremely difficult for the liquid to penetrate, thus achieving a relatively tight seal. The top of the condenser tube 3 is connected to the docking flange 104 via the connecting flange 302. A sealing gasket is provided between the connecting flange 302 and the docking flange 104, which further increases the tightness and gives this application a high sealing effect. The condenser tube 3 is fitted with the metal sealing sleeve 106, and the docking flange 104 and the connecting flange 302 can also be separated by removing the hexagonal bolts. The sealing cover 2 and the condenser chamber 1 can also be separated, so that this application can replace the condenser tube 3 while having a high sealing effect.

[0056] Third, when the gas enters the condenser tube 3 through the feed pipe 201, the structure of the condenser tube 3 is disrupted by the various through holes 301, which makes the gas contact the condenser tube 3 more fully. At the same time, the various through holes 301 can also increase the contact area between the condenser tube 3 and the coolant, increase the heat exchange efficiency, and make it have a high cooling efficiency.

[0057] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
