TOP1 three-way catalyst recovery equipment for precious metals
Application of equipment:
This equipment is used to receive TBRC slag, waste catalyst, flux,
FeSi alloy, etc. from the upper section, and reprocess the slag
products from the primary smelting step to achieve the best
recovery rate.
Product overview and structural features:
1) Select a fixed furnace body, semi-closed combined furnace cover;
2) Adopt fully water-cooled copper-steel composite conductive
transverse arm;
3) The short-net design uses the three-phase electrode triangle
connection method, which has good short-net compensation, low
impedance, low three-phase unbalance coefficient, high power factor
and significant power-saving effect;
4) The use of new water-cooled cable technology and forged copper
shingles, water-cooled cable and copper pipe connection selection
of button-type connection, which can reduce the contact resistance;
5) Adopt full hydraulic lock, the electrode lifting adopts
hydraulic proportional valve control lifting, combined with PLC
control, improve the operation rate of the electrode system;
6) Multi-point feeding in the furnace, to achieve continuous
uniform distribution, automatic control of the amount of material;
7) Magnesia-chrome bricks/aluminum-chrome bricks are used in the
furnace inner lining, the bricks at the bottom of the furnace, the
bricks at the bottom of the arch and the slag line, and the copper
water jacket is used for strong water cooling at the slag line. The
double water jacket design is used in the slag line to effectively
guarantee the service life of the refractory materials in the
furnace (2 years warranty for the side wall in contact with the
molten liquid, 6 years warranty for the side wall in non-contact
with the molten liquid, and 6 years warranty for the bottom of the
furnace);
Equipment composition:
The mechanical system is mainly composed of furnace body and copper
water jacket, furnace bottom air cooling system, semi-enclosed
furnace cover, electrode lifting system, smoke collecting system,
short mesh system, hydraulic system, cooling water system, blanking
system, mixing station, iron and slag extraction system, operating
steel platform, mixing and blanking steel platform, furnace lining,
etc. Electrical equipment is mainly composed of electric furnace
transformer, high voltage switchgear, low voltage control equipment
and automatic control system of electric furnace.
