Description

Technical Field

[0001] The invention relates to the technical field of pyrometallurgical equipment manufacturing, in particular to a device for collecting metal vapor condensate crystals. Background Art

[0002] At present, in the field of pyrometallurgy, high-temperature steam is mostly condensable gas. During the condensation and crystallization process, the heat of the steam is extracted through the convection heat transfer of the fluid on both sides of the condensation surface and the heat conduction between the walls, and the steam is transformed from the gas phase to the liquid phase. The liquid phase has fluidity, is easy to collect and control, and can realize continuous production operations.

[0003] As for the metal vapor that is directly condensed into metal crystals, the gas phase is directly transformed into the solid phase during the condensation process, and crystallizes and deposits on the condensation surface. After a period of time, the operation must be stopped to clean up the condensed crystals to prevent the air flow channel in the condenser from being blocked and affecting the production efficiency. Especially when working under vacuum conditions, the air tightness of the condensation crystallization device must be ensured first. As one of the processes of the entire production system, the condensation crystallization process must be disassembled as little as possible to ensure the stability and continuity of the working environment. The condensation crystallizers currently disclosed and used in enterprises cannot continuously remove and collect condensed crystals, and the production efficiency is low. Summary of the invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The present invention provides a device for collecting metal vapor condensate crystals, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, it includes a condensation main frame 1, in which a sealed cavity is formed, and both ends of the condensation main frame 1 are respectively provided with an air inlet 7 and an air outlet 8 connected to the sealed cavity. High-temperature metal-like vapor enters the condensation crystallization cavity through the air inlet 7, and the air outlet 8 is connected to a vacuum pump or a filtering device, so that operation under vacuum or normal pressure can be achieved; a plurality of condensation baffles 3 are fixedly arranged in the condensation main frame 1 in an alternating manner, and an air flow channel is formed between one end of the condensation baffle 3 and the adjacent inner wall of the condensation main frame 1, and two adjacent air flow channels are located on different sides, so that after the high-temperature metal-like vapor enters the interior of the condensation main frame 1 through the air inlet 7, it enters between the two condensation baffles 3 adjacent to the air flow channel through the nearest air flow channel, and then flows between the two condensation baffles 3 to the next air flow channel on the other side, and flows in a winding manner in sequence until it is discharged from the air outlet 8. During the process, most of the vapor condenses and crystallizes on the surface of the condensation baffle 3, forming a into solid condensed crystals; multiple scraper lifting mechanisms 2 are arranged on the top of the condensation main frame 1, and each scraper lifting mechanism 2 is connected to a knife head through a lifting rod penetrated through the top of the condensation main frame 1, and the knife head is located between two adjacent condensation baffles 3, and has a gap with the sides of the two adjacent condensation baffles 3; when the number of condensed crystals is too large, the scraper lifting mechanism 2 is started, or the scraper lifting mechanism 2 is started at a fixed time to drive the knife head to move downward, and then scrape off the condensed crystals on the side walls of the condensation baffles 3, and the collecting bin 6 is located at the bottom of the condensation main frame 1, and is fixedly and sealedly connected to the condensation main frame 1, the interior of the collecting bin 6 is connected to the sealed cavity, and an airflow guide plate 5 that can be opened and closed is provided between the collecting bin 6 and the condensation main frame 1, and the airflow guide plate 5 is usually horizontally closed to guide the flow of steam. When the knife head scrapes off the crystals, the airflow guide plate 5 rotates downward and is in an open state, and the scraped crystals fall into the collecting bin 6.

[0035] In this embodiment, the condensation main frame 1, the condensation baffle 3, the air flow guide plate 5 and the collection bin 6 are made of stainless steel, and the surfaces that may contact with the high-temperature steam are smoothed and galvanized.

[0036] In order to install the condensation baffle 3, a plurality of square grooves 9 are arranged alternately on the two side walls of the condensation main frame 1 in this embodiment. One end of the condensation baffle 3 is fixedly and sealedly arranged on the square groove 9, and the other end forms an airflow channel with the adjacent inner wall of the condensation main frame 1. In order to achieve a sealing effect, a strip-shaped sealing flange 12 is sealed and connected at the square groove 9 with a rubber ring or a sealing gasket. The sealing flange 12 is fixedly connected to one end of the condensation baffle 3. A sealing ring is also arranged at the position where the lifting rod is passed through the top of the condensation main frame 1. The lifting rod is in sliding and sealing contact with the sealing ring, so that the sealing is always maintained at this place during the lifting process of the lifting rod. The length of the condensation baffle 3 is smaller than the width of the main frame. Adjacent condensation baffles 3 are arranged oppositely and spaced apart. The spacing distance and the number of condensation baffles 3 are determined according to the properties of the metal-like vapor and the production situation. A heating body insertion hole 15 extending to the interior of the condensation baffle 3 is opened at the sealing flange 12. A heating body 4 is inserted into the heating body insertion hole 15. The temperature of the steam condensation crystallization atmosphere is controlled by the heating body 4. The heating body 4 can use a heating rod or a resistance wire as needed.

A limiting bolt 14 is passed through the limiting hole 10, and the end of the limiting bolt 14 is fixedly threadedly connected to the corresponding limiting hole groove 13, so as to fix the condensation baffle 3; in order to prevent the part of the limiting bolt 14 that contacts the steam from corroding, and at the same time, to avoid the phenomenon of steam condensation and crystallization in this part, which makes the limiting bolt 14 fail, a protective cover 16 is provided on the part of the limiting bolt 14 located between the limiting hole groove 13 and the limiting hole 10.

[0038] In this embodiment, two airflow guide plates 5 are provided at the bottom of the condensation main frame 1. One end of the airflow guide plate 5 is hinged to the side wall of the condensation main frame 1 or the side wall of the collection bin 6 by a hinge or a rotating shaft, and the bottom of the other end is connected to a driving cylinder, which can drive the airflow guide plate 5 to swing around the hinge point; when the two airflow guide plates 5 are in a horizontal position, the ends of the two airflow guide plates 5 away from the hinge point are in contact and connected, so that the condensation main frame 1 and the collection bin 6 can be closed to prevent steam from flowing into the collection bin 6. The bottom of the end of the airflow guide plate 5 away from the hinge point is hinged with an inclined cylinder or motor, which can drive the airflow guide plate 5 to rotate around the rotating shaft or hinge to achieve closing or opening. When closed, the irregular movement of metal vapor in the condensation crystallization process can be reduced, and when opened, the scraped crystals can fall into the collection bin 6.

When the other end is in a horizontal state, it can contact and connect with the side wall of the condensation main frame 1 or the collection bin 6 away from one end of the transmission shaft, thereby achieving the closure between the condensation main frame 1 and the collection bin 6. When the driving motor runs and drives the airflow guide plate 5 to rotate downward, the closed state between the condensation main frame 1 and the collection bin 6 can be opened, so that the condensation main frame 1 and the inside of the collection bin 6 are connected.

[0040] The scraper lifting mechanism 2 of this embodiment is hydraulically driven. The hydraulic cylinder is fixed to the top of the condensation main frame 1 through a bracket. The hydraulic telescopic rod at the bottom of the hydraulic cylinder is fixedly connected to the lifting rod.

The scraper 11 is made of cemented carbide. The scrapers 11 arranged in the front half of the condensation area of ​​the present invention are grouped into two, and the scrapers 11 in the back half of the condensation area are grouped into three. Each group of scrapers 11 can be lowered independently to achieve the scraping of condensed crystals on the side of the condensation baffle 3.

[0041] Embodiment 1

[0042] This embodiment uses the above-mentioned device to operate under a vacuum condition of 0.04MPa to 0.08MPa. Arsenic trioxide material with a purity of ≥90% is continuously processed to form arsenic vapor at 500°C to 600°C after front-end treatment, and enters the condensation area in the condensation main frame 1 through the air inlet 7. The air flow guide plate 5 is closed, and the arsenic vapor moves along the channel formed by the condensation baffle 3 and the condensation main frame 1. The surface temperature of the condensation baffle 3 is controlled within the range of 270°C to 450°C by the heating body 4. Most of the arsenic vapor condenses and crystallizes on the surface of the condensation baffle 3 during the movement. As the condensation operation time increases, the condensation baffle 3 The thickness of the crystallized arsenic on the surface increases continuously, and the scraper 11 at the front condensation area position drops after the condensation and crystallization operation starts. The adjacent group of scrapers 11 in the rear row starts to operate 20 minutes after the front group of scrapers 11 operates, so that the thickness of the crystallized arsenic on the surface of the condensation baffle 3 during cleaning is maintained in the range of 0.5cm to 1cm. After all the scrapers 11 operate once, the airflow guide plate 5 is quickly opened, and the scraped crystallized arsenic enters the collection bin 6, and the airflow guide plate 5 is closed. The operation is circulated in this way. After the crystallized arsenic in the collection bin 6 accumulates to a certain amount, the discharge valve is opened to take out the crystallized arsenic product, thereby realizing the continuous condensation and crystallization of arsenic vapor.

The device operates under a micro-negative pressure to a micro-positive pressure of -100Pa to 200Pa. The high-temperature arsenic vapor (700℃ to 800℃) obtained by high-temperature heating of the elemental arsenic raw material enters the condensation crystallization device. The air outlet 8 is connected to the induced draft fan to control the surface temperature of the condensation baffle 3 within the range of 150℃ to 400℃. The first group of scrapers 11 in the front condensation area starts working 30 minutes after the start of the condensation crystallization operation, and the adjacent group of scrapers 11 in the rear row starts to operate 20 minutes after the front group of scrapers 11, and the crystallized arsenic is scraped off to the collection bin 6 for collection. The whole device runs smoothly, has good corrosion resistance, and is easy to maintain.

[0045] Embodiment 3

[0046] The structure of the device used in this embodiment is the same as that of the first embodiment, except that this embodiment uses a cylinder to drive the scraper lifting mechanism 2, the scraper 11 is made of 316L stainless steel, the heating body 4 is made of nickel-chromium heating wire, the condensation baffle 3 is made of 304 stainless steel, and the steam condensation contact surface is titanium-plated. The process is carried out under vacuum conditions of 100Pa to 1000Pa. Arsenic trioxide vapor at 250°C to 300°C enters the condensation main frame 1 from the air inlet 7. The temperature on the surface of the condensation baffle 3 and in the air flow channel is controlled to be less than 200°C. The air flow guide plate 5 is kept in an open state. Two scrapers 11 are grouped together. The scrapers 11 in the front condensation area are lowered two hours after the start of the condensation crystallization operation. The scraper 11 in the rear row starts to operate 30 minutes after the front scraper 11 is operated. The thickness of the arsenic trioxide crystals deposited on the surface of the condensation baffle 3 during cleaning is maintained at 1.5cm to 2cm. When the arsenic trioxide condensate crystals obtained in the collection bin 6 accumulate to a certain amount, the air flow guide plate 5 is closed, the discharge valve is opened, and the collected arsenic trioxide condensate is taken out, thereby realizing continuous condensation and crystallization of arsenic trioxide vapor.
