Description
Technical field
The present invention relates to a kind of high-temperature liquid state material device for generating power by waste heat, it belongs to metallurgical industry field, particularly liquid high-temperature material cogeneration technology.
Background technology
The processing of steel-making slag is both at home and abroad stacked by dried slag the earliest is discarded.Develop into present hot vexed, hot application, crushing and screening is handled and method such as high pressure shrend, has realized the waste recovery utilization, makes it to be converted into regenerated resources.In the last few years; Because degradation each side under the ature of coal, faults such as the end dreg removing system of many power plant frequently stops up, wearing and tearing, and incident such as unplanned stoppage in transit repeatedly takes place; The boiler that has even can't normally move has a strong impact on the safe operation and the economic benefit of power power plant.Therefore the deslagging problem of boiler becomes domestic each ubiquitous problem of recirculating fluidized bed power plant.But there are deficiencies such as floor space is big, environmental pollution is serious, processing technology is complicated, installed capacity is high, water consumption is big, investment is big, production environment is abominable, the rate of recovery is low in above-mentioned the whole bag of tricks, and can't avoid slag to bring the explosion accident that molten steel produces into.
Summary of the invention
The technical problem that the present invention will solve provides that a kind of small investment, waste heat recovery efficient are high, wear rate is low, floor space is little, technology is compact, easy to operate, production environment good, water consumption is few and avoid slag or slag in have the explosion accident that the process of molten steel produces, the high-temperature liquid state slag is realized the device of direct granulation and exhaust heat recovery power generation.
The technical scheme that solves the problems of the technologies described above is:
A kind of high-temperature liquid state material device for generating power by waste heat comprises the granulation case that is provided with water-cooling wall, multistage fluidisation body of heater, waste heat boiler, the cold gas circulatory system and turbine generator.It is characterized in that, be provided with centrifugal granulation device, high-pressure fog shower nozzle, high pressure gas shower nozzle and fluidisation shower nozzle in the described granulation case; The high-temperature material passage that described multistage fluidisation body of heater inside is provided with from top to bottom comprises distribution cabins, multistage fluidisation shower nozzle and discharge chamber; The described cold gas circulatory system comprises cyclone dust collectors and circulating fan.
Beneficial effect:
1, the present invention greatly reduces the utilization of the water in the production process, has reduced input cost;
2, the present invention has significantly improved the heat recovery rate of high-temperature material, has reduced energy consumption and environmental pollution effectively;
3, the present invention has effectively avoided the incidence of equipment fault, has guaranteed normally carrying out of production.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the vertical view of the close interior fluidisation shower nozzle of dredging in multistage fluidisation stove China and foreign countries;
Accompanying drawing 3 is the vertical view of fluidisation shower nozzle close in multistage fluidisation stove is dredged at home and abroad.
The specific embodiment
Referring to accompanying drawing, the present invention is by centrifugal granulation rotating disc 1, liquid hopper 2, high-pressure fog shower nozzle 3, high pressure gas shower nozzle 4, granulation case 5, centrifugal granulation frequency-conversion and speed-regulation motor 6, fluidisation shower nozzle 7, circulating fan 8, interim storage bin 9, elevator 10, fluidizer 11, discharge chamber 12, waste heat boiler 13, cyclone dust collectors 14, solid-state hopper 15, cloth frequency-conversion and speed-regulation motor 16, rotation cloth tray 17, distribution cabins 18, steam turbine generator 19, breather line 20, multistage fluidisation body of heater 21, material channel 22.
The high-temperature liquid state material has liquid hopper 1 to get in the granulation case 6; Drop on the centrifugal granulation rotating disc 2 of charging aperture below; Centrifugal granulation rotating disc 2 drives the liquid towards material by centrifugal granulation frequency-conversion and speed-regulation motor 5 and carries out granulation;, cooled off the material of granulation when breaking away from centrifugal granulation rotating disc 2 by the liquid spraying of high-pressure fog shower nozzle 3 ejections; The gases at high pressure that sprayed by high pressure gas shower nozzle 4 then cool off and slow down horizontal impact speed, and the gas of the fluidisation shower nozzle ejection of the fluidizer 7 of granulation case 6 bottoms slows down the downward impact velocity of material and further cools off.Material after the granulation is put into interim storage bin 10 and is waited for that elevator rises on the solid-state hopper 15.
Material through granulation case 5 granulations gets into distribution cabins 18 through solid-state hopper 15, drops on the rotation cloth tray 17 on distribution cabins 18 tops, through rotation cloth tray 17 material is evenly arranged on the one-level fluidisation shower nozzle 7 of distribution cabins 18 bottoms.Being arranged as of described one-level fluidisation shower nozzle is outer close interior thin, and the too much material that drops on the periphery is drawn close to the centre gradually, makes material even gradually.Through getting into next stage fluidisation structure the material channel 22 of material between fluidisation shower nozzle 7 of one-level fluidisation cooling, through being provided with heat exchanger between the first order and the afterbody fluidisation structure and circulated air cools off material.Material through multistage fluidisation is discharged from discharge chamber 12.
The circulation cold gas is got in the granulation case 5 by circulating fan 8 tentatively to be cooled off high-temperature material; By infeeding in the multistage fluidisation body of heater 21 after circulating fan 8 pressurizations material is carried out the fluidisation cooling more afterwards; The circulation cold gas of coming out from multistage fluidisation body of heater 21 enters into cyclone dust collectors 14 and carries out dedusting; Cool off with waste heat boiler 13 heat exchange in the circulation cold gas entering waste heat boiler 13 by cyclone dust collectors 14 discharges, cooled circulation cold gas gets into circulating fan 8 and gets into next cyclic process.
Heat exchanger tube in the multistage fluidisation structure is the part of waste heat boiler 13, and the steam that waste heat boiler 13 produces is accomplished the acting generating through steam turbine generator 19.
