Abstract
The utility model provides a waste heat recovery/power generation engineering system device for a belt/ring cooling machine of a sintering machine. Smoke which is recovered from an outlet chimney of the belt cooling machine of the sintering machine enters a boiler through a mixing section; a draught fan, a tee flapper valve, a main chimney and a chimney bracket are arranged at an outlet of the boiler; a circulating fan is arranged at the other outlet of a tee baffle plate; and circulated air is led in a cooling air section of the belt cooling machine; and a corresponding cooling blower is turned on or turned off in operation. The waste heat recovery/power generation engineering system device has the advantages of reliable operation, relatively stable operating conditions, a high heat-energy recovery rate and the like.
Description
(1) technical field
The utility model relates to steel works sintering machine belt-cooling machine waste heat recovery/generation engineering system and device, is to reclaim the flue gas of discharging in the belt-cooling machine cooling procedure of steel works sintering machine the package deal technical equipment of generating specifically.
(2) background technology
Powdered during the mineral aggregate supplied materials of steel plant, the technological process of steel-making is earlier mineral aggregate to be smelt iron and then to add other elemental composition by demand to be smelt steel.Mineral aggregate need add coal dust (imitation frosted glass), quick lime, dolomite and combustion adjuvant etc. in mineral aggregate in advancing the blast furnace ironmaking process carries out few sintering and makes it become block in sintering machine.After material behind the high temperature sintering enters belt-cooling machine and cools off, deliver to smelting shop ironmaking.Belt-cooling machine is similar to the traveling-grate stoker of boiler, being furnished with several air blasts under the chain-type steel chain row of belt-cooling machine continuously dries, chain row slowly move in cooling air with the block mineral aggregate behind the high temperature sintering, cooling air passes chain row and the high temperature mineral aggregate becomes the mixing high-temperature flue gas, through being located at the chimney discharge that chain row top links to each other with case.
(3) summary of the invention
It is a kind of reliable that the purpose of this utility model is to provide, and can make the operating condition check and correction stable, the sintering machine band that heat energy recovery rate is high/central cooler waste heat recovery/generation engineering system and device.
The purpose of this utility model is achieved in that reclaiming sintering machine belt-cooling machine outlet chimney smoke enters boiler by mixer, boiler export is furnished with air-introduced machine, threeway flapper valve, main chimney and chimney support, circulating fan is arranged in another outlet of threeway flapper valve, and circulated air is introduced belt-cooling machine cooling air section and stop corresponding cooling blower when operation.
The utility model also has some technical characterictics like this:
1, the flue gas of described waste heat recovery/generating is taken from sintering machine belt-cooling machine cooling air/cigarette outlet chimney or petticoat pipe;
2, the flue gas of described waste heat recovery/generating is drawn chimney, contains the case on the sintering machine belt-cooling machine, adopts inside and outside insulation form, and internal insulation structure is that expanded metal lath is the abrasion-proof and refractory cement layer of keel, and outer insulation is insulation material kalamein shell;
3, described perpendicular to the chimney support employing constant force spring bearing of drawing chimney;
4, described chimney top of drawing flue gas installs the top intercepter valve (IV) additional, during waste heat recovery the chimney top flue gas is blocked;
5, described flue system adopts boiler export flue gas recirculation flue system, and circulation cigarette wind is introduced belt-cooling machine cooling air inlet bellows, and effect is to improve the boiler entrance flue gas temperature;
6, described air-introduced machine and circulating fan bearing are selected the sliding bearing formula for use;
7, described waste heat boiler adopts vertical/horizontal flue, and horizontal/vertical heating surface, exhaust pass is provided with ash exhauster.
Advantage of the present utility model is mainly reflected in:
(1) the utility model is the energy recovery/electricity generation system design library part editor and reuse in a kind of useless flue gas that the sintering machine cooling can be produced, its application can make the bigger reduction of big steel cost of steel plant, and the recycling economy cycling rate improves (internal rate of return (IRR) can reach 20%～25%)
(2) adopt the native system design library part editor and reuse, can reduce soot emissions, reduce atmosphere pollution, improve environment.
(3) native system design library part editor and reuse thermal efficiency height is reliable, and the investment payback time is short.
