Background technique
Slag is the by product of steel industry, and every production 3t molten steel approximately just generates 1t slag (about 1500 ℃), have the 1.8GJ sensible heat to be released approximately, and these sensible heats is not also recycled effectively at present.Carry out the utilization of slag waste heat recovery, can reduce energy consumption, calculate, approximately can reduce greenhouse gas emission 300,000 t every year according to the replaced energy (coal or rock gas).
Usually way is slag to be placed on carry out natural cooling in the slag bath and handle, then landfill or as roadbed material.In modern steel factory, blast furnace slag takes the shrend granulated processed to become glassy particles more and more, is used for the admixture of Portland cement.When producing Portland cement, every use 1t blast furnace slag just can make cement industry reduce the carbon dioxide of the about 0.8t of discharging.But this way can effectively not reclaim the heat in the slag, and in whole world energy starved today, so Duo heat is wasted as heat extraction.
Along with further going deep into of slag granulation technical research, it is ripe that dry granulation slag technology has been tending towards, and Given this, derived the afterheat of slags recycle device thus.The sensible heat in the high efficiente callback slag how, the afterheat of slags that makes full use of after the granulation becomes a current key technology difficult problem.
Summary of the invention
The technical problem that solves
Perfect along with the slag granulation technology; the sensible heat of slag is recycled into for development in future trend; but general heat recovering device just reclaims the slag sensible heat by indirect heat exchange, and it is low to have reuse efficiency, and the Processing capacity of slag charge is subjected to waste heat recovery apparatus and handles quantitative limitation.
Technological scheme
Provide following technological scheme for solving above technical problem the utility model:
This high temperature sludge exhaust heat recovery power generation device, mainly by centrifugal granulation device, pipeline feeder, material boiler, steam turbine, cooler is formed, and described centrifugal granulation device is connected with the material boiler by the pipeline feeder; Described material boiler internal is furnished with fluidizer, vaporizer, superheater, deflection plate, economizer; Described material boiler discharge port is connected with cooler.
Arranged around at the centrifugal granulation device has high pressure to swash sprinkler head, and in conjunction with the Processing capacity that has increased slag, the amount of controlling high pressure water simultaneously guarantees the drying in the centrifugal granulation device by centrifugal granulation and high pressure shrend granulation.The steam that comes out from the centrifugal granulation device enters drum after by the steam purifier purified treatment; the pipeline feeder is delivered to the material boiler to material by feeding pipe by power plant; material pipe has been outside equipped with thermal insulation layer; thermal material passes through fluidizer fire box interior superheater and vaporizer after entering the material boiler; superheater is arranged in material boiler furnace material feeding mouth and smoke inlet place; the steam that comes out from superheater enters steam turbine; the material boiler also comprises the primary dust removing device; with the two-stage dust removal device, described primary dust removing device is connected with the cooler material inlet by pipeline.The water of the heat exchange by cooler can be sent into drum.
Beneficial effect
The utility model is a high temperature sludge exhaust heat recovery power generation device, begins to spray lotic water granulation molten slag on the one hand by high-pressure nozzle from slag granulation, directly produces steam on the one hand, can enter drum by the steam after purifying.After slag granulation, promote material by the pressure piping that has thermal insulation layer and carry out indirect heat exchange to the material boiler, carry out the high efficiente callback utilization of heat of slags.By multistage waste heat recovery apparatus, it is big to have treating capacity, slag charge treatment effeciency height.
