Abstract
The utility model belongs to the technical field of waste heat recovering and utilizing technique of a sintering machine, in particular to a waste heat recovering and utilizing device of induced air of main pumping of a sintering machine. The utility model is characterized in that a waste heat boiler is arranged in a big air flue or an air box of a sintering machine, and the waste heat boiler is connected with a steam using device. The waste heat boiler can be arranged in big air flues in or behind 4-6 air boxes on the aftermost position of the sintering machine whose waste gas temperature is highest in general case. The waste heat boiler is a heat pipe type waste heat boiler or a finned tube type waste heat boiler. The waste gas flow process according to the waste heat recovering and utilizing device of induced air of main pumping of a sintering machine is that the waste gas flows through a big air flue or an air box of a sintering box, a waste heat boiler, the big air flue or the air box of the sintering box, an electric precipitator on the machine head, a main pumping draught fan, a main air flue and atmosphere in turn. The temperature of waste gas in a big air flue in or behind 4-6 air boxes on the aftermost position of the sintering machine can reach 350 degrees, and the temperature of waste air after heat is absorbed by a waste air boiler can be lowered by 150 degrees to 200 degrees.
Description
Technical field
The utility model belongs to sintering machine heat recovery technology field, and particularly a kind of sintering machine master takes out air inducing heat recovery equipment.
Background technology
Economizing on resources and protecting environment is the key subjects that interior quite over a long time at present and in the future socio-economic development must be faced and solve.Energy-saving and emission-reduction will have influence on all trades and professions through economic life in the long term as a fundamental state policy.How technically, address these problems from the source steel industry is high flow rate, high pollution " rich and influential family ",, and then promote the great development of steel industry, has become the extremely urgent vital task of our scientific and technological enterprises.
The sintering circuit energy consumption is only second to ironmaking and occupies second in iron and steel enterprise, also be the rich and influential family of energy waste simultaneously, in SINTERING PRODUCTION, sintering hot waste gas when hot-air when energy loss mainly is ring type, straight line cooler cooling sintering deposit and sintering machine master take out air inducing, reclaiming this part heat has significant meaning to industry energy conservation synergy, in reducing cost.Present sintering machine master takes out air inducing and enters large flue via each bellows, after the dedusting of head electric cleaner, is introduced main chimney and is entered atmosphere by the main air-introduced machine of taking out, waste heat in the air inducing can not be recovered, and contain a large amount of dust, directly enter atmosphere, very big to ambient influnence, simultaneously, contain a large amount of iron filings in this part dust, very high recovery value is arranged, enter atmosphere, both influence environment, wasted resource again.
Summary of the invention
The purpose of this utility model provides a kind of sintering machine master and takes out air inducing heat recovery equipment.
The purpose of this utility model realizes by following technical proposals:
Take out air inducing heat recovery equipment according to sintering machine master of the present utility model, it is characterized in that in the large flue of sintering machine or in the bellows waste heat boiler being set, this waste heat boiler is connected with the steam operative installations.
