一、Heat treatment processing method

Pyrolysis carbonization of waste batteries is an important recycling technology, the main purpose is to remove organic matter in the battery through pyrolysis process, while realizing the separation and recovery of metals and other valuable materials.

There are many pyrolysis and carbonization technologies for waste batteries, including high temperature pyrolysis, low temperature pyrolysis, gradient pyrolysis, anaerobic carbonation pyrolysis, solvent pyrolysis and so on. Each technology has its advantages and disadvantages and scope of application, and it is necessary to choose the appropriate technology for application according to the actual situation.

Zhengzhou Dingli New Energy Technology Co., Ltd. is a comprehensive scientific and technological innovation private enterprise under Zhengzhou Dingli Group specializing in the research and development of new energy equipment technology. It has the comprehensive ability of integrating scientific research, development, production, sales and service. It has deep technical accumulation and rich production experience in the field of carbonization pyrolysis technology, and is a manufacturer specializing in the production of carbonization pyrolysis equipment.

About the pyrolysis and carbonization technology of waste batteries, you can consult Dingli technical engineers in detail, Dingli Group has more than 300 strategic partners in the world, any equipment needs, please feel free to contact us!

二、Wet treatment

The wet treatment technology of waste batteries is based on the principle of metal materials and chemical substances dissolved in acid in batteries, in addition to batteries, various types of batteries are dissolved in sulfuric acid, and then with the help of ionic resin to extract various metal materials from the solution, the raw materials obtained in this way are pure specific heat treatment methods.

三、Superheated steam heat treatment method

When processing waste batteries, there are generally two specific methods: one is to warm old batteries at low temperatures, which can extract volatile mercury, and second hand recovery of zinc and other heavy metals when the ambient temperature is higher. The second is to roast the waste battery at high temperature, so that the volatile metal materials and oxides of which are volatile, and the residues can be used as intermediate products in the metallurgical industry or treated separately.

四、 Solidified, buried and stored in abandoned shafts

Waste batteries are generally transported to specialized toxic and hazardous waste disposal sites, but this approach is often very expensive and leads to waste, because there are many useful materials that can be used as raw materials.
