AI Technical Summary

Problems solved by technology

Due to the hexachloroethane contained in the waste fuming agent, a large amount of hydrogen chloride will be produced during the incineration process, and hydrogen chloride will form hydrochloric acid when it meets water, which will cause corrosion to metal fireplaces and chimneys, and will eventually affect the use of the incineration and destruction system Effect and service life
Because the fuming agent will produce fuming reaction at high temperature and produce high concentration of zinc chloride fume, it is easy to block the dust filter and flue, causing accidents
It can be seen that the incineration of waste fuming agents containing hexachloroethane has the following defects: 1. The loss of equipment is huge
2. Accident prone
3. Serious environmental pollution
4. The waste disposal process is cumbersome and costly
5. The zinc chloride produced is very harmful to the human body

Embodiment 1

[0030] Weigh 5.00g of waste fuming agent containing hexachloroethane and add it to the sublimation tank, and pump the sublimation tank to a vacuum of 0.01MPa. At the same time, turn on the circulating water of the condensation tank, and then heat the sublimation tank to 100°C. Do not turn on the stirring, at this time, the sublimated hexachloroethane vapor enters the condensation tank from the sublimation tank through the pipe connecting the sublimation tank and the condensation tank, and crystallizes on the inner wall of the condensation tank; after the sublimation is completed, stop heating and vacuumize , take out the hexachloroethane solid crystallized on the inner wall of the condensation tank.

Embodiment 2

[0032] The amount of raw material used in this example is 10.00g, with stirring, the stirring rate is 24r / min, the degree of vacuum is 0.01MPa, the heating temperature is 100°C, and the other conditions and steps are the same as in Example 1.

Embodiment 3

[0034] The amount of raw materials used in this example is 10.00g, with stirring, the stirring rate is 24r / min, the vacuum degree is 0.01MPa, the heating temperature is 120°C, and the other conditions and steps are the same as in Example 1.

Abstract

The invention discloses a sublimation treatment method of a waste smoke agent containing hexachloroethane. The method comprises the following steps: adding the waste smoke agent containing the hexachloroethane in a sublimation tank and vacuumizing the sublimation tank; then heating the sublimation tank; transporting hexachloroethane steam after sublimation to a condensation tank from the sublimation tank, and crystallizing on the inner wall of the condensation tank; and after finishing the sublimation, taking out the hexachloroethane solid crystallized on the inner wall of the condensation tank. The sublimation treatment method of the waste smoke agent containing the hexachloroethane has the advantages of low cost and high recovery, and is simple.

Description

technical field [0001] The invention relates to a treatment method for waste fuming agents, in particular to a sublimation treatment method for waste fuming agents containing hexachloroethane. Background technique [0002] The main component of the smoker contained in most fuming canisters is hexachloroethane. Due to various reasons, there are often some scrap fume pots that need to be disposed of in time. At present, the treatment method for the waste fuming agent in the discarded fuming pot is mainly to carry out incineration and destruction. The main process is to disintegrate the waste ammunition, feed the material into the incinerator through the feeder, then perform pretreatment, and burn at different temperatures in the first combustion chamber and the second combustion chamber, and finally spray and burn the burned gas. Degradation, dust removal and other treatment, after passing the test, it is discharged into the atmosphere. Due to the hexachloroethane contained...
