Pyrolysis gas treatment system for recycling waste batteries

Abstract

The invention discloses a pyrolysis gas treatment system for recycling waste batteries. The pyrolysis gas treatment system comprises a waste treatment system, a cracking system and a waste gas purification system, wherein the waste treatment system comprises a waste treatment tank, rolling rollers are rotationally installed in the waste treatment tank, one ends of the two sets of rolling rollers are fixedly connected with driving motors, and a discharging pipe is fixedly installed at the bottom of the waste treatment tank; the cracking system comprises a high-temperature cracking furnace, theend, away from the waste treatment tank, of the discharging pipe is fixedly connected with the high-temperature cracking furnace, a water heating device is fixedly installed on the side, close to thebottom, in the high-temperature cracking furnace, and a heat storage device is fixedly mounted in a high-temperature electrolytic furnace and located above the water heating device; and the waste gaspurification system comprises a conveying pipeline and a flue gas purification device, and the conveying pipeline is fixedly connected between the heat storage device and the flue gas purification device. The pyrolysis gas treatment system has the beneficial effects that heat loss in the secondary heat exchange process is reduced, the energy utilization rate is increased, environmental protectionis achieved, and energy conservation and consumption reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of waste battery treatment, in particular to a cracking gas treatment system for recycling waste batteries. Background technique [0002] The recycling of waste batteries refers to the recycling of used batteries. The most widely used industrial batteries in China are lead-acid batteries, and lead accounts for more than 50% of the total cost of batteries. Pyrochemical, hydrometallurgical and solid-phase electrolytic reduction technologies are mainly adopted. . The shell is made of plastic, which can be recycled, and basically achieves no secondary pollution. [0003] Lithium-ion battery is a rechargeable chemical battery with good comprehensive performance. It has the advantages of high working voltage, high specific energy, long cycle life, and small self-discharge. It is widely used in mobile communications, notebook computers, portable tools, and electric vehicles. and other fields. Due to the large co...
