Technical introduction

waste lead-acid battery recycling

Through three generations of development, the comprehensive recovery technology of waste lead-acid battery has developed from the first generation of extensive technology of reverberatory furnace to the melting pool smelting technology of oxygen enriched side blowing furnace. The process of comprehensive recovery of waste lead-acid battery by oxygen enriched side blowing furnace can be divided into single furnace process and double furnace process.
Our company's waste lead-acid battery comprehensive recovery technology with re paste side blowing furnace as the main equipment is in an advanced position in China. It is an excellent joint supplier of oxygen enriched side blowing furnace and overall solution in China. It has been applied in more than 10 recycled lead recovery enterprises in China and has been widely praised.
Our company can provide users with technical consultation, factory design, equipment and installation services for the whole process of waste lead-acid battery recycling according to the needs of users.

Double furnace process

  • advantage:

    The SO2 concentration in the flue gas of oxidation furnace can be stable At 2.7 ~ 3%, the acid production is more stable.

    shortcoming:

    The investment of the two furnaces, the consumption of fuel, oxygen and labor, has increased the investment and operation cost; The concentration of SO2 in the flue gas of oxidation furnace is low, which still can not meet the requirements of direct acid production, and the acid can be produced only after ionic liquid concentration is also required; Coal is added to the reduction furnace, and the flue gas needs desulfurization. If ionic liquid absorption is adopted, the investment of ionic liquid will be increased.

Core equipment

RE type lead paste side blowing furnace is composed of hearth, copper water jacket and vertical flue. Using anthracite as reducing agent, anthracite, natural gas or a combination of both can be used as fuel according to the needs of users. The water jacket adopts the form of three-layer copper water jacket, equipped with primary air duct and secondary air duct, and can be equipped with natural gas spray gun according to the needs of users.
