Efficient iron-containing waste acid treatment structure

Abstract

The invention discloses an efficient iron-containing waste acid treatment structure. The device comprises a tank body; a stirring mechanism is mounted at the bottom of the tank body; aeration holes are uniformly distributed in the inner side wall of the tank body; the stirring mechanism comprises a motor positioned below the tank body, a shaft body output by the motor, and blades driven by the shaft body; the shaft body extends into the tank body from the bottom of the tank body in a sealed mode; the blades are located in the tank body; a waste acid inlet and a waste acid outlet are formed inthe top and the bottom of the tank body respectively; an interlayer is formed on the side wall of the tank body, and annular heating bodies are evenly distributed in the interlayer. Through the annular heating bodies and a thermal insulation material, the device is effectively subjected to heating operation and heat preservation operation, the synthesis efficiency is high, the process is simple, the space utilization rate is high, the cost is reduced, manpower and labor are saved, the aeration mechanism is arranged on the side wall surface of the whole reaction kettle, the radiation surface islarge, and the reaction speed can be increased.

Description

technical field [0001] This application relates to the waste acid treatment industry, in particular to a high-efficiency iron-containing waste acid treatment structure. Background technique [0002] The main component of iron-containing waste acid is ferrous chloride or ferrous sulfate. The technology of producing spherical iron ferric oxide by using waste acid as raw material has been developed. This technology can convert iron ions in waste acid Become ferric oxide with high added value. However, in the prior art, since there is no special synthesis processing equipment, the synthesis of ferroferric oxide is relatively cumbersome, and it needs to be synthesized on different reaction equipment, resulting in low synthesis efficiency of ferric oxide, complex and cumbersome procedures , The equipment affects the space utilization rate and labor-intensive problems in the workshop. [0003] The company applied for a patent on January 09, 2018: a device for treating waste acid ...
