Embodiment Construction
[0032] Preferred embodiments are listed below to further illustrate the purpose, features and effects of the present invention.
[0033] The 350-400℃ calcining tail gas discharged from the tail of a sulfuric acid titanium dioxide production rotary kiln with an annual capacity of 60,000 tons is connected to a multi-tube ceramic cyclone through the main flue of the rotary kiln, and then passed into waste heat after the cyclone dust removal In the boiler system, 90% of the titanium dioxide dust in the calcined tail gas is collected in the collector at the lower part of the multi-tube ceramic cyclone, which can be recycled and transferred to the beating tank for beating process.
[0034] The waste heat boiler system includes a tail gas channel and a cooling water channel. The tail gas channel and the cooling water channel respectively flow through a deaerator, a hot water heater with longitudinal fin heat pipes, a heat pipe evaporator and a steam concentrator. After cyclone dust remova...
