Reactor rack for preparing germanium tetrafluoride

Abstract

This invention relates to a reactor rack for preparing germanium tetrafluoride, belonging to the field of chemical equipment. The reactor rack for preparing germanium tetrafluoride is characterized by comprising a rack and a rack cover. The rack cover covers the rack, which is a horizontally placed columnar structure with an open top and a partially enclosed bottom. One end of the bottom half is closed, while the other end is open. A semi-circular ring is vertically welded to one end of the top half, while the other end is closed, with the semi-circular ring located on the closed end of the bottom half. A support plate is welded to the opening at the top of the rack, and the support plate is aligned with and of equal length to the opening. This reactor rack for preparing germanium tetrafluoride is simple in structure, scientifically designed, and easy to use. Placing the material on the rack cover and then placing the rack together into the reactor effectively prevents the material from contacting the reactor's inner wall, thus avoiding burning the reactor's inner wall during the fluorination reaction.

Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment, specifically relating to a reactor material rack for preparing germanium tetrafluoride that avoids direct contact between materials and the inner wall of the reactor during the reaction, and facilitates the loading and unloading of materials and cleaning of the reactor. Background Technology

[0002] The reaction between fluorine and germanium requires a specific reaction temperature and is highly exothermic, which can burn and corrode the reactor. Existing technologies all suffer from this problem, such as:

[0003] Chinese Patent 200980138501.3 discloses a method for manufacturing germanium tetrafluoride, which involves reacting diluted fluorine gas with a germanium block heated to a certain temperature and then condensing and collecting the germanium tetrafluoride. However, in practice, the reaction heat between the fluorine gas and the germanium block causes localized burns to the reactor.

[0004] Chinese Patent 201921837493.9 discloses a method for preparing germanium tetrafluoride by adding germanium powder into an inclined rotating heating tube, passing fluorine gas from the bottom and using a flap to lift the germanium powder to react, filtering and condensing the germanium tetrafluoride. However, the added germanium powder is in direct contact with the reaction vessel, making it difficult to control the heat of reaction, increasing the risk of burns to the reaction vessel, and the germanium tetrafluoride product may carry germanium powder and introduce impurities, affecting the purity of the product.

[0005] Chinese Patent 202121251530.5 discloses three methods for preparing high-purity germanium tetrafluoride in an apparatus for preparing germanium tetrafluoride. In this method, germanium powder is heated in an independent isolated heater and then enters the reactor for reaction. The reaction is rapid, but during the reaction, germanium powder still falls onto the reactor, causing burns and corrosion on the reactor contact surface. In addition, the equipment is complex to manufacture and the operation process is cumbersome. Summary of the Invention

[0006] The main purpose of this invention is to solve the problems existing in the prior art and provide a reactor material rack for preparing germanium tetrafluoride that avoids direct contact between the material and the inner wall of the reactor during the reaction, and facilitates the loading and unloading of the material and cleaning of the reactor.

[0007] The reactor feed rack for preparing germanium tetrafluoride of this utility model is characterized in that the reactor feed rack includes a feed rack and a feed rack cover plate, wherein the feed rack cover plate covers the feed rack, wherein:

[0008] The material rack is a horizontally placed columnar structure with a semi-enclosed design, open at the top and enclosed at the bottom. One end of the bottom half is closed and the other end is open. A semi-circular ring is vertically welded to one end of the top half, and the other end is closed. The semi-circular ring is located on the closed end of the bottom half. A support plate is welded to the opening at the top of the material rack. The support plate is in the same direction and of the same length as the opening of the material rack.

[0009] The rack cover is placed on the support plate, covering the opening of the rack.

[0010] The material rack cover plate is provided with holes at equal intervals.

[0011] The rack and rack cover are made of Monel alloy or Hastelloy alloy and the surface is mirror polished to ensure the purity and tolerance of germanium tetrafluoride gas.

[0012] The reactor rack for preparing germanium tetrafluoride of this invention has a simple structure, scientific design, and is easy to use. The material is placed on the rack cover plate and then placed into the reactor along with the rack, which effectively avoids the material from contacting the inner wall of the reactor and prevents the inner wall of the reactor from being burned during the fluorination reaction.

[0015] The components include: 1. Material rack; 2. Material rack cover; 3. Semicircular ring; and 4. Support plate. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] As shown in the figure, a reactor feed rack for preparing germanium tetrafluoride includes a feed rack and a feed rack cover, wherein the feed rack cover covers the feed rack, and:

[0018] The material rack is a horizontally placed columnar structure with a semi-enclosed design, open at the top and enclosed at the bottom. One end of the bottom half is closed and the other end is open. A semi-circular ring is vertically welded to one end of the top half, and the other end is closed. The semi-circular ring is located on the closed end of the bottom half. A support plate is welded to the opening at the top of the material rack. The support plate is in the same direction and of the same length as the opening of the material rack.

[0019] The rack cover is placed on the support plate, covering the opening of the rack.

[0020] The material rack cover plate has holes at equal intervals.

[0021] The rack and rack cover are made of Monel alloy or Hastelloy alloy and the surface is mirror polished to ensure the purity and tolerance of germanium tetrafluoride gas.

[0022] The length of the material rack is designed according to the size of the reactor, typically 50cm-80cm, and the diameter is 50cm-60cm, including but not limited to these dimensions and shapes. The specific dimensions can be designed according to the inner diameter, shape, and size of the reactor. The size of the material rack cover plate is designed to match the size and shape of the material rack.

[0023] In practice, the germanium ingot is broken into flat, thin pieces to increase the contact area with fluorine gas, making the reaction easier. The broken germanium pieces are placed directly on the cover plate of the upper part of the material rack, which is then placed into the reactor. The handle of the semi-circular ring on the upper part of the material rack is positioned in the direction of the fluorine gas inlet. The approximate flow direction of the fluorine gas is from the upper semi-circular ring, through the broken germanium pieces, through the cover plate, and to the outlet of the lower part of the material rack. The introduced fluorine gas does not require dilution; 99% pure fluorine gas can be directly introduced into the reactor. The reaction rate can be controlled by the amount of fluorine gas introduced.
