Problems solved by technology

As an example of related technology, the treatment method of discharging waste batteries in sulfuric acid for about 14 to 20 days, drying them and then pulverizing them uses sulfuric acid, which is harmful to workers and the working environment, so there is a possibility of high incidence of occupational diseases among workers rate, and there is a hidden danger of fire and gas poisoning when the battery is dry
Also, the processing time takes a long time, so not only the process efficiency is reduced, but also there is a problem of causing serious environmental pollution when the solution used in the processing process flows out.

Embodiment 1

[0046] Example 1: Roasting Treatment of Waste Electric Vehicle Batteries

[0047] The waste batteries of electric vehicles are conveyed through the first pipe 111 inclined at 5° to 15° with respect to the ground and provided with a spark plug at one end. The heat treatment is performed at a temperature of 800° C. for 30 minutes to 120 minutes. The heat-treated substance has been transported through the second pipe 112 which is connected with the first pipe 111 and is inclined 5° to 15° relative to the ground. At this time, water is sprayed on the outer peripheral surface of the second pipe 112, And cooling water is circulated at the end of the second pipe 112 so that the temperature of the calcined material discharged through the second pipe 112 is 70°C to 100°C.

[0048] The harmful gas generated during the heat treatment is conveyed through the third pipe 211 communicated with the first pipe 111 , and the heating mechanism sprays flames in the direction of conveying the har...

Embodiment 2

[0049] Embodiment 2: electric tool battery roasting treatment

[0050] In the first embodiment, except that an electric tool battery is used instead of an electric vehicle battery as the battery to be used, the same method as in the first embodiment is used to perform the baking treatment of the battery and the cooling and dust collection treatment of the gas.

Embodiment 3

[0051] Embodiment 3: the roasting treatment of circular button battery

[0052] In the above-mentioned embodiment 1, except that the battery to be used is replaced by a circular button battery instead of an electric vehicle battery, the roasting treatment of the battery and the cooling and dust collection treatment of the gas are carried out in the same manner as in the above-mentioned embodiment 1. .

Abstract

The invention provides a battery roasting and roasting gas dust collection treatment method. The battery roasting and roasting gas dust collection treatment method comprises the following steps: (1) roasting waste batteries conveyed to a single direction through a closed pipe at the temperature of 400-1000 DEG C, and discharging the waste batteries; and (2) carrying out heat treatment on the gas generated in the roasting process in step (1) to 600-900 DEG C, and then carrying out cooling and dust collection treatment. When the method is used for roasting the batteries, the generated harmful gas components can be minimized, and the method has the advantages that the disassembly treatment time of the waste batteries can be obviously shortened, and the labor cost can be obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of waste battery treatment, and in particular relates to a battery roasting and roasting gas dust collection treatment method. Background technique [0002] As is well known, batteries used for portable devices, electric vehicles, etc. include a positive electrode, a negative electrode, an electrolytic solution for electrically connecting the positive electrode and the negative electrode, a separation film for preventing short circuit, the positive electrode, the negative electrode and the separation film It is accommodated in a square case or a cylindrical case formed with a positive electrode terminal and a negative electrode terminal to form a battery cell. [0003] The demand for such batteries is on the rise as the consumption of devices that require electric power such as portable devices and electric vehicles increases. The battery has a predetermined life depending on the environment in which it is ...
