いる。(2) Conventional technology At present, mercury-containing batteries are attracting attention as a new source of pollution, and the Environment Agency and local governments are struggling to recover and dispose of them. Collection methods have begun to include taking old used batteries to retailers when purchasing new ones, while methods of disposal include landfilling them with general waste or packing them in concrete. I'm doing it.
しかしながら、水銀含有電池の需要の延びはめざましく

る。また、電池に含有されている水銀は無機水銀である
か、廃棄されたのちバクテリヤ並びに他の有機物と反応
して毒性の高い有機水銀となる可能性がある。However, the demand for mercury-containing batteries has increased dramatically, and securing a disposal site has become a problem with the above-mentioned image processing methods. Furthermore, the mercury contained in the battery may be inorganic mercury, or after being disposed of, it may react with bacteria and other organic substances to become highly toxic organic mercury.
このため、水銀含有電池の安全かつ確実な処理方法の開
発が望まれる。Therefore, it is desired to develop a safe and reliable treatment method for mercury-containing batteries.
（、（）発明が解決しようとする問題点この発明は上記

提供することを目的とする。(, () Problems to be Solved by the Invention The present invention takes the above points into consideration and aims to provide a safe and reliable method for treating mercury-containing batteries.
（４）問題点を解決するための手段
この目的達成のため、この発明の処理方法にあっては、

ものである。(4) Means for solving the problem In order to achieve this objective, the processing method of this invention includes:
A mercury-containing battery is heated in an incinerator to vaporize the mercury, and the exhaust gas containing vaporized mercury and dust is sent to a cooler to liquefy and store the mercury, and the exhaust gas from which mercury has been removed is sent to a dust collector. It is designed to be released into the atmosphere through the air.

んも排気ガスとともに排出される。(A 52-acting mercury-containing battery is usually one in which zinc and mercury oxide are placed in a sealed steel container with an electrolyte layer interposed between them. When this battery is heated and incinerated at 600 to 700°C, mercury is released. teeth,
Zinc has a boiling point of 3569°C, so it is vaporized and discharged together with the exhaust gas, and since zinc has a melting point of 419°C and a boiling point of 970°C, it remains in a molten state as a residue along with other metals such as iron. In addition, combustion produces dust, which is also emitted along with the exhaust gas.

ガスは水銀、粉じんなとか除去されているため、無害な
ものである。In the past, vaporized mercury and dust were mixed into the exhaust gas, and by cooling it, only the mercury, which has a boiling point lower than that and an even lower melting point (-38.7℃), liquefied and dripped into the storage tank. The exhaust gas from which mercury has been removed is removed by a dust collector and discharged into the atmosphere. This exhaust gas into the atmosphere is harmless because mercury and dust have been removed.
