Tianneng Project Description

In 2011, the GME’ engineers followed the Battery Recycling Plant Project with ZHEJIANG TIANNENG SOURCE MATERIAL CO., LTD, P. R. China. > In the project, which built a Battery Breaker plant with a capacity of 25  tons per hour in Changxin county,  Huzhou, Zhejiang our Engineers were responsible for the engineering, procurement, execution and the installation supervision.

Performed activities: 2011, battery recycling plant cap. 150.000 tpy supplying, with

Battery breaker unit, 25 tph capacity, including

Pre-crusher by 1st hammer mill in SS316
Acid (electrolyte) draining by screening
Drained acid collecting & filtering
Aerosol droplet pollution colletion by suction points on breaker and wet scrubbing before discharding to atmosphere, execution in polypropylene
Paste collecting into stirred tank with pump transferring to de-sulphuration unit 
Crushed material separation into SS316 tanks with water
Breaker acid water filtering to charge to de-sulphuration unit 

Paste de-sulphuration unit, 400 tpd capacity, including: 

Couple of insulated & SS316 made stirred reactors
Soda feeding to reactors by dense-phase system
SS316 vortex pump feeding the de-sulphurated paste slurry to filter press
SS316 filter press 6,5 m3 capacity, with bottom pannels cake conveyor transferring to deposit.
Heavy metals salt solution removal unit
Salt solution polishing filter press
Anydrous sodium sulphate crystallization, detergent quality, with water condensation for re-using in the de-sulphuration process
