Industrial crude iodine desublimation device

Abstract

The invention discloses an industrial crude iodine desublimation device. The industrial crude iodine desublimation device comprises a machine body; a sealing cover is arranged above the machine body;a gas inlet pipe is arranged above the machine body; a manual valve is arranged above the gas inlet pipe; a ceramic protective cover is arranged in the gas inlet pipe in a sleeving manner; an elasticfilter plate is arranged below the ceramic protective cover; a cooling water ring is arranged outside the elastic filter plate in a sleeving manner; a drainage plate is arranged on the inner wall above the sealing cover. The equipment is provided with an inlet of the cooling water ring for steam to enter the equipment, so that precooling is conducted in advance when the steam enters the equipment,one part of heat in the steam is taken away, the speed and the yield are prevented from being greatly reduced during high-temperature steam desublimation, the economic benefit is improved and the practicability is enhanced; in addition, the equipment is provided with a first cooling plate and a second cooling plate, the equipment is divided into multiple areas, and after the steam enters the equipment, the final yield is greatly increased through desublimation of multiple areas.

Description

technical field [0001] The invention belongs to the technical field of crude iodine purification equipment, in particular to an industrial crude iodine desublimation device. Background technique [0002] Iodine is known as the element of life and wisdom. It is an indispensable element for the growth of human body and plants, a raw material for creating inorganic or organic iodides, and a good catalyst for many chemical reactions. Products are widely used in food, medicine, industry, agriculture, national defense cutting-edge technology and many other industries. In medicine, iodine has great disinfection and antiseptic effects. It can oxidize the active gene of bacterial cytoplasmic protein, and combine with the amino group of protein to make it denatured, and can kill bacteria, fungi, viruses and Abanba protozoa. It is usually used in the manufacture of fungicides, disinfectants, deodorizers, tranquilizers, etc. The desublimation device is essential for the purification ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of industrial thick iodine desublimation device, when using desublimation device to carry out desublimation crystallization to iodine vapor to solve the above-mentioned background technology, because it is directly passed into equipment so can have certain The heat greatly reduces the speed and output during desublimation, making the economic benefit low and not practical, and most of the equipment can desublimate each time due to the fixed volume of the equipment, so the iodine content that can be desublimated each time is relatively small. The output is less, the output is low, and once the production is to be increased, only multiple equipment can be used, which leads to cumbersome and complicated machines, time-consuming and labor-intensive labor consumption, low economic benefits and low practicability, and most of the equipment is in the process of condensation. Huahou directly discharges the exhaust gas after simple treatment, and this also causes the iodine in the exhaust gas to be discharged, which causes a lot of waste of raw materials and increases the cost of raw materials, low economic benefits and low practicality.
