Description
Technical field
The present invention relates to dry dust removal equipment field, particularly relate to a kind of novel antiknock explosion-proof type vertical flue-pipe formula heat pipe
Waste heat boiler.
Background technology
1, steelmaking converter flue gas belongs at metallurgy industry and most having specific characteristics flue gas, and flue gas itself has three large resources:
One is that cigarette temperature is high---reach 800～1000 DEG C；
Two is high containing CO---reach more than 70%；
Three is containing ferrum oxide, calcium oxide dust height---reach 80～150g/m3.
When this three large resource is integrated in one, gas cleaning becomes a difficult problem, uses to high-temperature flue gas spray cooling both at home and abroad for this
Dust collecting process, this technique includes OG method, LT method.
The dust collecting process of converter gas water spray, flue gas is to be purified, but the usefulness of three large resources, then become to minimize:
High temperature heat cannot recycle, coal gas becomes and then loses original calcium oxide ferrum oxide characteristic containing water and steam coal gas, stove dirt.
OG method, LT method consume great lot of water resources during water spray cleaning:
OG method often refines one ton of steel need to spray recirculated water 3--5 ton；LT method is often refined one ton of steel and need to be sprayed water 0.2 ton, spraying steam 0.025 ton, removes
The process of dirt is i.e. the process consuming water resource in a large number.
While OG method, LT method consume great lot of water resources during water spray cleaning, part water becomes steam, then increase
Exhaust gas volumn, blower fan power consumption increases therewith.
For not water spray cleaning converter gas can be realized, research and develop through team, make more than a kind of antiknock explosion-proof type vertical flue-pipe formula
Heat boiler [has obtained national inventing patent (Authorization Notice No. CN 102094104 B)].Described waste heat boiler is from cooling converter cigarette
Gas, recovery converter gas waste heat aspect of performance, reached technological requirement, and had cost advantage.Become first generation converter gas
Cooling, waste heat reclaiming process equipment.
2, the particularity that steelmaking converter produces.
Current steelmaking converter is smelted, and is to match with continuous casting, need to supply molten steel at regular time and quantity.To this end, converter smelting can not
Occur affecting continuous casting situation.This proposes requirements at the higher level, i.e. waste heat boiler in the configuration of converter gas cooling residual heat boiler can not
Break down and affect the smelting of converter.The heat exchanger tube of waterpipe type waste heat boiler, all in boiler furnace, its length reaches myriametre, weldering
Mouth is thousands of, and leaking such as occurs in any point, and repairs a few days at least, then converter cannot be smelted, and certainly will affect continuous casting.
To this end, research and development adapt to converter smelting feature high-temperature flue gas not water-spraying control synchronize energy recovery new technology and with
Supporting new technology equipment.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of for steelmaking converter high-temperature flue gas not water-spraying control synchronization heat
Energy recovery process,--high temperature, high dust, high CO and guarantor's continuous casting--the not water-spraying control of seriality characteristic to tackle converter gas
A kind of converter high-temperature flue gas heat energy of technique is converted into Steam Recovery process watertight new technology equipment-novel antiknock explosion-proof type
Vertical flue-pipe formula heat pipe waste heat boiler.
For reaching above-mentioned purpose, a kind of novel antiknock explosion-proof type vertical flue-pipe formula heat pipe waste heat boiler of the present invention, it includes directly
Vertical tubular body of heater and the external support structure of body of heater, body of heater cross section is rectangle or circle, and described body of heater corner is respectively provided with one
Square air-cooled column, arranges some horizontal ring beams between four furnace stays, constitute general frame structure；Furnace wall it is provided with inside ring beam,
Furnace wall is made up of furnace wall and heat insulation layer, and furnace wall is welded for thick shell plate, is welded with T-shaped support, inside T-shaped support inside furnace wall
Being welded with hexsteel, T-shaped support and the heat insulation layer that hexsteel is skeleton are divided into inside and outside two-layer, outer layer is that heat-insulation layer, internal layer are for high
Strong wearing layer；Outside furnace wall containing laterally and stand to reinforcement；Furnace wall is equipped with adopting heat pipes for heat transfer element, and heat exchange element is mutual-inserting type
Arranging, furnace body inside is that described heat pipe release end of heat is sheathed in water pipe, water for heat pipe release end of heat outside heat pipe heat absorbing end, body of heater
Pipe is provided with water inlet and steam port；Body of heater from bottom to up, is followed successively by boiler cooling section, economizer section, evaporation I section, evaporation section Ⅱ,
As superheated steam need to be produced, then between evaporation I, II section, add superheat section；Heat pipe release end of heat makes steam header, respectively with vapour
Bag connects, and constitutes steam natural cycle system；It is respectively equipped with ball storehouse and storehouse valve at body of heater, constitutes the ball soot cleaning system that falls, automatically
Peace and quiet heat exchange element dust stratification, it is ensured that exhaust gases passes is unobstructed and heat exchange efficiency.
The invention difference from existing technology is that the present invention achieves following technique effect:
High-temperature flue gas of the present invention not water-spraying control synchronizes energy recovery technique, and compared with water spray craft existing with converter, flue gas becomes
Pure dry flue gas；Smoke heat energy is converted into steam, recycles.
Antiknock explosion-proof type vertical flue-pipe formula heat pipe waste heat boiler of the present invention is imitated with conventional upright chimney flue type water pipe residual heat boiler for exchanging heat
The most identical, but there is great advantage on the whole:
Vertical flue-pipe formula heat pipe waste heat boiler the most of the present invention, not water flowing in body of heater, the probability that boiler does not leak, more adapt to
Steelmaking converter smelt demand, do not have waste heat boiler leak affect steel-making accident generation；
Heat pipe waste heat boiler the most of the present invention, service life is longer, even if there being a small amount of heat pipe to damage, nor affects on boiler operatiopn；
3. after reaching life cycle, it is convenient to change, and can take whole group of replacing, is not required to change boiler overall structure；
4. site installation test is convenient, because, before dispatching from the factory, packet section suppresses test, is conducive to improving boiler quality；
5. carrying out outside body of heater because of steam/water circulating, pipeline shortens relatively, and resistance is damaged relatively low, is therefore not required to install forced circulation
Pump, thus reduce power consumption；
6. more preferably, furnace wall thickeies for safety, unfailing performance, and intensity improves, and air-tightness improves, and more adapts to steelmaking converter flue gas and contains
CO, the characteristic of high dust.
Present invention process is equipped steelmaking converter cooled flue gas waste heat recovery waterpipe type vertical flue-pipe formula waste heat boiler
Upgrading, concentrates its advantage, in addition heat pipe advantage, forms steelmaking converter cooled flue gas waste heat recovery brand-new vertical flue-pipe formula waste heat pot
Stove.
