Problems solved by technology

This kind of cooling method, which is common in the domestic carbon industry, not only evaporates a large amount of water resources, but also causes thermal pollution to the environment.
[0003] At present, the waste heat in the discharge and flue gas of the carbon calciner has not been effectively utilized, and the synergistic purification effect on various pollutants in the flue gas is poor, which needs to be improved urgently

Abstract

The invention relates to a calcination furnace waste heat power generation system, and belongs to the technical field of energy saving devices. The calcination furnace waste heat power generation system comprises a calcination furnace, a smoke waste heat boiler, a bag type dust remover, a desulfurizing tower, a steam turbine generator unit, a steam condenser, a condensate pump, a deaerator, a feedpump, a roller slag cooler and a demineralized water tank. An exhaust outlet of the calcination furnace communicates with the smoke waste heat boiler, and a discharging outlet of the calcination furnace communicates with the roller slag cooler. A fuel gas spark plug is arranged in the smoke waste heat boiler, and a combustion chamber outlet of the smoke waste heat boiler is connected with a cyclone separator. A superheater, a denitration device and a smoke cooler are arranged in a tail vertical shaft of the smoke waste heat boiler, and the exhaust end of the tail vertical shaft communicates with the bag type dust remover through a flue. The bag type dust remover communicates with the desulfurizing tower through an induced draft fan, and the steam exhaust end of the superheater is connected with a steam inlet door of the steam turbine generator unit through a steam pipe. By the adoption of the calcination furnace waste heat power generation system, the waste heat in discharged materials and discharged smoke of the carbon calcination furnace can be converted into the electric energy, and efficient and collaborative purification of various pollutants in the smoke of the calcination furnace is achieved.

Description

technical field [0001] The invention belongs to the technical field of energy-saving devices, and in particular relates to a calciner waste heat power generation system. Background technique [0002] After the petroleum coke is calcined in the carbon calciner, the temperature of the discharge (calcined coke) is about 1000°C. According to the heat balance calculation, the heat absorbed by the calcining of raw materials only accounts for 33.5% of the calciner’s thermal expenditure, and is taken away by the calcined flue gas The heat accounted for 47.9% of the thermal expenditure of the entire calciner. The flue gas contains dust, asphalt fume, sulfur dioxide, nitrogen oxides, etc. The flue gas volume is large, the concentration of pollutants is high, and it contains a variety of carcinogenic components. Many manufacturers use water cooling to cool the discharged material to below 200°C, and discharge it into the vibrating screen and transmission belt to achieve the purpose of...
