Abstract
The invention discloses a secondary-aluminum smelting afterheat power-generation device, and relates to the technical field of resource recovery. The secondary-aluminum smelting afterheat power-generation device comprises multiple boilers arranged abreast. Each boiler is provided with a vapor outlet connected with a vapor output branch pipe, and each vapor output branch pipe is connected with a vapor output main pipe that is connected to a motor unit. Vapor generated by the boilers drives the motor units to work, and the motor units drive generator units to work and output power. Flues of the boilers and exhaust pipes of the motor units are connected to a flue gas heat exchanger that is connected to a jacket water heat exchanger, and heat generated by the jacket water heat exchanger is output to the vapor output main pipe or used for supplying heat for life. The secondary-aluminum smelting afterheat power-generation device has simple process, is convenient to operate in practice, and capable of recovering and converting afterheat into high-temperature vapor for power generation by the boilers, and thus at least 50% of afterheat is recovered and utilized.
Description
Technical field
The present invention relates to resource reutilization technical field, be specifically related to a kind of secondary aluminium smelting residual heat generating device.
Background technology
Secondary aluminium is the indispensable resource of aluminium industrial sustainable development, compare with aluminum production, secondary aluminium per ton can be saved the energy and reach 95%, the noxious emissions such as carbon dioxide greatly reduce, not only save the energy, environment purification, the production cost that can also greatly reduce Al-alloy products, has good Social benefit and economic benefit.
Secondary aluminium is smelted waste heat and is accounted for 60% of fuel energy, and directly discharge waste is serious.Due to S0 in secondary lead smelting exhaust
2large Deng harmful gas concentration, corrosivity is strong, and containing the higher easy obstruction heat absorbing conduit of lead dust, therefore, general cogeneration facility is difficult to directly application in reviver industry, in addition the equipment that also there is no at present the cogeneration of more ripe applicable reviver enterprise, so that up to now, because of in there is no reviver enterprise and utilize waste heat to generate electricity.
Summary of the invention
