Problems solved by technology

It does not specify the soaking time, nor does it introduce how to deal with the final reactants, whether it is harmless, etc.; and there are safety hazards in deep burial treatment. If it is accidentally dug out, it will cause great social impact and the environment. Cause pollution, so it is necessary to improve the treatment method of the existing gas adsorbent to improve the safety after treatment

Embodiment Construction

[0017] The present invention will be further described below in conjunction with embodiment:

[0018] A treatment method of a sulfur hexafluoride circuit breaker gas adsorbent of the present invention comprises the following steps:

[0019] ① Take the residual gas adsorbent and other harmful gas substances in the sulfur hexafluoride circuit breaker and pump them into the gas storage tank;

[0020] ② Take 25%~35% of the residual gas adsorbent mass fraction into a strong alkali solution and add it to the gas storage tank to neutralize the residual gas adsorbent. In this example, 30% of the residual gas adsorbent mass fraction is used Strong alkaline solution for neutralization reaction;

[0021] ③Pour the solution obtained in step ② into the container;

[0022] ④ Add CaCl to the solution in the container in step ③ 2 solution, AlCl 3 The solution is reacted, and the order of adding the inorganic salt solution is to add CaCl first 2 Inorganic salt solution and then add AlCl ...

Abstract

The invention relates to a processing method of a sulfur hexafluoride breaker gas adsorbent. Chemical reagents react with harmful gas substances comprising the of sulfur hexafluoride gas adsorbent and the like, so the harmful gas substances are converted into nontoxic inorganic salts, thereby a leftover problem after traditional gas adsorbent processing is solved; and the adopted reagents are common chemical reagents, so the processing cost of the harmful gas substances is saved, thereby the processing method has very large practicality and popularization values.

Description

technical field [0001] The invention relates to a treatment method for harmful substances in sulfur hexafluoride circuit breakers, in particular to a six-six- Treatment method of sulfur fluoride circuit breaker gas adsorbent. Background technique [0002] Retrieval of relevant patent documents has not yet found a treatment method for sulfur hexafluoride circuit breaker gas adsorbent that is the same as the present invention. Sulfur hexafluoride circuit breaker gas adsorbent, which is used to absorb the decomposition products of sulfur hexafluoride circuit breaker gas after arc extinguishing; because the sulfur hexafluoride gas in the sulfur hexafluoride circuit breaker has to withstand Under the action of high voltage, high current and high temperature, the gas produces certain decomposition products. [0003] The decomposition product is highly toxic, and improper disposal will affect personal safety and environmental protection. At present, there are generally two ways ...
