Problems solved by technology

[0004] There is no suitable arsenic purification device in the prior art. Quartz products can be used to make simple rectification devices, but they are not suitable for arsenic purification. It is difficult to increase the purity of arsenic to four nines, and the existing annealing methods have many restrictions on quartz devices. Many theoretical designs cannot realize industrial application

[0047] The rectifying tower head includes a blind pipe 11, a reinforced water pipe 12, an outlet pipe 13, an exhaust pipe 14, a primary outlet pipe 15, a final outlet pipe 16, a reinforced water inlet pipe 17, and a temperature measuring pipe 18; the dead pipe includes The inner wall 111, the outer wall 112, the first barrier structure 113, the second barrier structure 114, the third barrier structure 115, and the fourth barrier structure 116; there is a gap between the outer wall and the inner wall; the end of the inner wall is sealed with the outer wall The end face of the inner wall is higher than the end face of the outer wall; the lower part of the outer wall is provided with a water inlet 117 communicating with the gap; the water inlet is higher than ...

Embodiment 2

[0061] On the basis of Embodiment 1, the following technical points are added:

[0062] The inside of the hollow spherical body is provided with a temperature measuring tube 38; the distance between the temperature measuring tube and the bottom of the hollow spherical body is 40mm, see the attached Figure 12 .

Embodiment 3

[0064] The method for arsenic purification using the arsenic purification and rectification device described in Example 2 comprises the following steps:

[0065] (1) Install the existing primary material connection bottle at the outlet of the primary outlet pipe; install a storage bottle at the outlet of the final outlet pipe, and combine the ball bowl structure at the end of the arsenic outlet pipe with the sealing ball head of the final outlet pipe; The outlet of the trachea is equipped with a tail gas collector; the existing vacuum pump is used to evacuate the column and the storage bottle;

[0066] (2) Add the material to be purified into the hollow spherical body from the feed port, and seal the feed port with a sealing plug; then turn on the heating (245°C) and circulating water, and start the rectification process;

[0067] During this process, the rectification steam passes through the circular partition to the escutcheon, and then is discharged from the vent hole comb...

Abstract

The invention discloses an arsenic purifying and rectifying device and a method for purifying arsenic through same. The arsenic purifying and rectifying device comprises a rectifying tower head, a rectifying tower column and a rectifying tower kettle, wherein the rectifying tower head comprises a blind tube; the blind tube comprises an inner wall, an outer wall, a reinforced water tube, a water outlet tube, an exhaust gas tube, a primary outlet tube, an end outlet tube, a water inlet tube of the reinforced water tube, a first blocking structure, a second blocking structure, a third blocking structure and a fourth blocking structure; the rectifying tower column comprises a through tube and a circular separating plate; the circular separating plate is mounted on the inner wall of the throughpipe and is provided with a plurality of through holes; the rectifying tower kettle comprises a hollow spherical body, and the surface of the rectifying tower kettle is provided with a material portand a rectifying tower column joint; one end of the rectifying tower column is mounted on the rectifying tower kettle through the rectifying tower column joint, and the other end of the rectifying tower column is connected to the opened end of the blind tube. With the adoption of the device for purifying arsenic, the effects of outstanding purifying effect, safe purifying process and long servicelife can be achieved; the coarse product of which the purity is 99.99% can be purified to be the fine product of which the purity is 99.99999%.

Description

technical field [0001] The invention belongs to the technical field of rectification and purification, and in particular relates to a rectification device for arsenic purification and a method for purifying arsenic by using the device. Background technique [0002] Arsenic (As) is an element that exists widely and has metalloid properties. It is a gray rhombohedral crystal with a metallic luster. It is neither soluble in water nor acid. It is a non-essential element for the human body. The Clarke value is 5×10 -4 , with a cosmic abundance of 4.0. For the public, arsenic is a synonym for poison, but it has good application properties. For example, in the preparation of high-performance glass, adding arsenic as an ingredient will help flux; it is also used in some semiconductors and colored glazes. [0003] Quartz is one of the most widely distributed minerals on the surface of the earth. There are many types of quartz, such as veined quartz, quartz sand, quartzite, sandstone...
