SSWQL weak sulfuric acid concentration graphite column used with titanium dioxide kiln tail gas(graphite Venturi)

Detailed Product Description

Patent Number:ZL 01 2 17393.2

A great amount of waste acid is generated during the process of sulfuric acid method to produce titanium dioxide (approximately contains 20% H₂SO₄, 10%FeSO₄). Treatment and recovery of these waste acids are an important issue in environment protection and development in sulfuric acid method to produce titanium dioxide. In the mean time ,a large volume of rolling kiln hot tail gas at about 300~450 is let out directly to atmosphere , much thermo energy is wasted and pollution is caused to the air.

The concentration and recycling system for waste diluted sulfuric acid adopts Titanium Dioxide Kiln Tail Gas weak sulfuric acid concentration graphite column as one of the main equipments, uses the new material of PTFE impregnated graphite, treats the hot tail gas from rolling kiln and the diluted waste sulfuric acid comprehensively, to reduce energy consumption and to solve the problem of two pollution sources, double effects with single effort.

Working conditions: inlet gas temperature of 100~550 is allowable while the flow rate and pressure of spraying liquid are fixed.
