Abstract
The utility model provides a waste heat power generation system for an ore-smelting electric furnace, which has the advantages of simple structure, low cost and high waste heat recovering efficiency. The waste heat power generation system includes a waste heat boiler provided with a waste gas inlet and a waste gas outlet, a coal economizer mounted in the waste heat boiler, and an evaporation heated surface. The waste heat power generation system for the ore-smelting electric furnace, which is provided by the utility model, has a simple structure, can improve the steam parameter at an inlet of a steam turbine, fully utilizes the waste heat exhaust gas of the ore-smelting electric furnace and converts to the electric energy furthest, so that the waste heat power generation capability is strong, and the system can not only lower the energy consumption and facilitate the resource conservation, but also protect the environment.
Description
Technical field
The utility model relates to a kind of generating equipment, especially a kind of ore deposit hot stove waste heat power generation system.
Background technology
The hot stove in ore deposit is semiclosed electric furnace mostly, and it has not only solved the technological operation problem of smelting, and has created condition for effectively solving flue gas cleaning and heat recovery technology; The exhaust gas volumn that semiclosed electric furnace produces is 10～15 times of totally-enclosed exhaust gas volumn, and approximately nearly 50% energy consumption all is that sensible heat form with low-temperature flue gas enters atmosphere in process of production, has not only wasted heat energy but also contaminated environment.Yet present mineral heating furnace flue waste heat does not reclaim basically, and is low mainly due to flue-gas temperature, and the waste heat recovery initial cost is high; Flue dust is not handled preferably in the flue gas, and waste-heat recovery device can not get continuous operation, and retracting device maintenance operation cost is high.
The utility model content
The purpose of the utility model provides a kind of ore deposit simple in structure, that cost is low, waste heat recovery efficient is high hot stove waste heat power generation system.
Realize a kind of ore deposit hot stove waste heat power generation system of the utility model purpose; Comprise the waste heat boiler that has exhaust gas inlet and waste gas outlet, be contained in economizer and evaporating heating surface in the said waste heat boiler; The port of export of said economizer is communicated with the drum of said waste heat boiler; The arrival end of said evaporating heating surface is communicated with the hydrospace of the drum of said waste heat boiler; The port of export is communicated with the air space of the drum of said waste heat boiler; The main shaft of said steam turbine connects with the rotating shaft of generator, and the saturated vapor outlet of the drum of said waste heat boiler is communicated with the saturated vapor import of steam superheater, and the superheated steam output of said steam superheater links to each other with the steam input of said steam turbine; The steam output end of said steam turbine links to each other with the input of condenser, and the output of said condenser links to each other with the input of economizer; The input of said economizer and output also are connected with flash vessel, and the output of said flash vessel communicates with steam turbine.
The beneficial effect of the utility model is following:
A kind of ore deposit hot stove waste heat power generation system of the utility model, simple in structure, can improve steam turbine inlet steam parameter; Make full use of the waste heat flue gas of the hot stove in ore deposit, change into electric energy to greatest extent, the cogeneration ability is strong; Not only can cut down the consumption of energy, promote resources conservation, and protect environment.
