Abstract
The invention discloses a comprehensive utilization system for waste heat and waste pressure in sulfuric acid production. The comprehensive utilization system comprises a fluidized bed combustion boiler, a waste heat boiler, a steam turbine and an electric generator. An air outlet of the fluidized bed combustion boiler is connected with an air inlet of the waste heat boiler. An air outlet of the waste heat boiler is connected with an air inlet of the steam turbine. The steam turbine is coaxially connected with the electric generator. The comprehensive utilization system is characterized by further comprising a crystallization tank, a curing kiln and a condensate water collection pool. An air outlet of the steam turbine is connected with an air inlet of the crystallization tank. An air outlet of the crystallization tank is connected with a spray device of the curing kiln. The bottom of the curing kiln is connected with a water inlet of the condensate water collection pool. A water outlet of the condensate water collection pool is connected with a water inlet of the fluidized bed combustion boiler. According to the comprehensive utilization system, the waste heat and the waste pressure are utilized comprehensively, so that the purpose of stepped use of energy is achieved, and the comprehensive utilization system has great significance in saving energy.
