Problems solved by technology

[0004] There is no suitable mercury purification device in the prior art. Quartz products can be used to make simple rectification devices, but they are not suitable for mercury purification. It is difficult to increase the purity of mercury to 4 nines, and the existing annealing methods have many restrictions on quartz devices. Many theoretical designs cannot realize industrial application

Abstract

The invention discloses a mercury purification rectification device and a method for purifying mercury by using the same. The mercury purification rectification device comprises a rectifying tower head, a rectifying tower column, and a rectifying tower kettle; the rectifying tower head comprises a blind pipe. The blind pipe comprises an inner wall, an outer wall, a reinforced water pipe, a water outlet pipe, a tail gas pipe, a primary outlet pipe, a final outlet pipe, a first hindering structure, a second hindering structure, a third hindering structure, and a fourth hindering structure; the rectifying tower column comprises a through pipe and a circular separating plate; the circular separating plate is installed on the inner wall of the through pipe, and provided with a plurality of through holes; the rectifying tower kettle comprises a hollow spherical body, and the surface of the hollow spherical body is provided with a material port and a rectifying tower column connector; one endof the rectifying tower column is installed on the rectifying tower kettle through the rectifying tower column connector, and one end is connected with an opening end of the blind pipe. The device isused for purifying the mercury, the effects of excellent purification effect, safe purification process and long service life can be achieved, and a mercury crude product of which the purity is 99.99% can be purified to a 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 mercury purification and rectification device and a method for purifying mercury by using the device. Background technique [0002] Mercury has a high density (13.6g / cm 3 ), low melting point (-38.87°C), and boiling point of only 357°C, it has important uses in chemical industry, electrical appliances, instrumentation, medicine, metallurgy, military industry and new technology fields. With the continuous improvement of the device performance level, the device has higher and higher requirements for the purity of the material, especially the very long-wave mercury cadmium telluride device and the single-photon avalanche device. In order to improve the junction resistance and increase the reverse breakdown voltage, The requirement for material purity is higher, but the purity of commercially available raw material mercury is relatively low, and ...
