Problems solved by technology

However, because the indigenous lead smelting (blast furnace lead smelting) technology used in their production process has disadvantages such as low energy utilization rate, large exhaust gas emissions, and large pollution, it has always been explicitly prohibited by the national environmental protection department.

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment, further illustrate the present invention.

[0024] The main core of the process is to crush the waste batteries and sort them by a hydraulic separator to obtain waste sulfuric acid compounds (paste), polyvinyl chloride plastics, polypropylene plastics, hardwoods, and alloy grid materials, and make these materials The impurity content is less than five thousandths, and then processed separately. Among them, after the paste and grid enter the natural gas rotary kiln, crude lead and waste gas (the waste gas contains large SO 2 and large amounts of lead dust). After the exhaust gas is collected, it first passes through the cooling tower to cool down, then enters the bag filter for dust removal, and then sends it to the desulfurization equipment for desulfurization, and finally passes through the air compressor and presses it into the filter chamber for moisture absorption and filtration. After reaching no pollu...

Abstract

The invention discloses secondary lead processing technology and device. It includes secondary lead material-waste acid sulfur cell processing technology and natural gas burning system in which the waste acid is smashed, filtrated, smelted; the waste gas is dusted, desulphurized, and filtered by natural gas rotary kiln which uses natural gas as fuel, air as combustion additive and their air input is controlled by a set of PC auto electronic valve. Its advantages are that it can save energy sources, ensure operation safe, and reduce harm for human; it has reached high secondary recovery and low waste pollution. Thus it has obvious social and economic benefits.

Description

technical field [0001] The invention relates to a solid recovery process and device, more specifically a regenerated lead processing process and device. Background technique [0002] my country is a big country of battery production and consumption. With the rapid growth of lead-acid battery production, a large amount of refined lead is produced and consumed. At the same time, a large number of waste batteries are produced every year. One is resource consumption, and the other is environmental pollution. Old battery pollution has become an urgent issue. The major environmental problems that need to be solved, scrapped batteries have become the main renewable source of lead, leading to the development of secondary lead production. my country's secondary lead industry is currently in a situation of disorderly development and extensive management. Many small enterprises across the country use backward technology or even indigenous methods to recycle and smelt lead, at the cost o...
