Problems solved by technology

That is, a method of recovering as an alloy by oxidizing elements with low added value such as iron as much as possible to slag, and suppressing the oxidation of elements with recovery value such as cobalt as much as possible, but there is a problem of separation in the dry method. Complete, high cost disadvantages

Embodiment 1

[0021] S001. Heating water to 140°C to form wet saturated steam;

[0022] S002. Under the condition of constant volume, continue to heat the wet saturated steam until it turns into dry saturated steam, and continue to heat the dry saturated steam to 250°C to form superheated steam;

[0023] S003. Keep the temperature at 250°C and the pressure at 1.0Mpa, decompose the organic matter inside the battery, leaving only metal solids in the furnace, and other decomposed matter will be carried out with the steam and dissolved in the water, and then the water will be treated , extract useful metal ions and organic matter, and remove harmful substances.

Embodiment 2

[0025] S001. Heating water to 140°C to form wet saturated steam;

[0026] S002. Under the condition of constant volume, continue to heat the wet saturated steam until it turns into dry saturated steam, and continue to heat the dry saturated steam to 700°C to form superheated steam;

[0027] S003. Keep the temperature at 700°C and the pressure at 0.1Mpa, decompose the organic matter inside the battery, leaving only metal solids in the furnace, and other decomposed matter will be carried out with the steam and dissolved in the water, and then the water will be treated , extract useful metal ions and organic matter, and remove harmful substances.

Embodiment 3

[0029] S001. Heating water to 140°C to form wet saturated steam;

[0030] S002. Under the condition of constant volume, continue to heat the wet saturated steam until it turns into dry saturated steam, and continue to heat the dry saturated steam to 500°C to form superheated steam;

[0031] S003. Keep the temperature at 500°C and the pressure at 0.5Mpa, decompose the organic matter inside the battery, leaving only metal solids in the furnace, and other decomposed matter will be carried out with the steam and dissolved in the water, and then the water will be treated , extract useful metal ions and organic matter, and remove harmful substances.

Abstract

The invention discloses a treatment method of a used battery. The treatment method comprises the steps that superheated steam is used for treating the used battery, only metal solid is left in the used battery, and other decomposer of the used battery enters steam. According to the treatment method of the used battery, the superheated steam is used for treating the used battery, splitting separation is performed to the used battery by thehydrone characteristics, separation of organic matters and the metal solid is simply and efficiently realized, and at the same time the treatment method of the used battery has the advantages that the separation cost is low.

Description

technical field [0001] The invention belongs to the field of recycling waste batteries, in particular to a treatment method for waste batteries. Background technique [0002] Treatment methods for recovering valuable metals contained in used lithium-ion batteries or defective batteries in the production process (hereinafter referred to as "waste batteries") are roughly divided into dry methods and wet methods. The dry method is to melt the broken waste batteries, and separate and recycle valuable metals and other metals with low added value, etc., by using the difference in oxygen affinity between them. That is, a method of recovering as an alloy by oxidizing elements with low added value such as iron as much as possible to slag, and suppressing the oxidation of elements with recovery value such as cobalt as much as possible, but there is a problem of separation in the dry method. Integrity, the disadvantage of high cost. Contents of the invention [0003] The object of ...
