Description
Technical field
It the utility model is related to TRT technical field, more particularly to a kind of converter fume excess air dry process hair
Electric installation.
Background technology
The flue gas of mini-medium BOF plants production at present adds wet dedusting using flue residue heat stove, and system recovery waste heat is few, and has
Part coal gas emptying causes to waste, and wet dedusting causes the waste of a large amount of water, and recirculated water need to set sewage disposal, iron powder recovery
Using difficulty, and later stage fume treatment has explosion danger again, and need to set gas chamber, system complex.It is therefore, it is proposed that a kind of
Converter fume excess air dry process TRT, this process system capital equipment are flue combustion apparatus, waste-heat oven recovery
Waste heat, storage heater, sack cleaner, Turbo-generator Set etc..Whole system uses dry type mode, wastes, is not required to without waste heat
Water resource is consumed, iron powder recycles simple.
Utility model content
The purpose of this utility model is the flue gas of mini-medium BOF plants production at present in order to solve shortcoming present in prior art
Wet dedusting is added using flue residue heat stove, system recovery waste heat is few, and has part coal gas emptying to cause to waste, and wet dedusting is made
Into the waste of a large amount of water, and recirculated water need to set sewage disposal, and iron powder recycles difficulty, and later stage fume treatment has blast again
Danger, and gas chamber, system complex need to be set.A kind of and converter fume excess air dry process TRT proposed.
To achieve these goals, the utility model employs following technical scheme：
A kind of converter fume excess air dry process TRT, including converter are designed, the converter is arranged including converter
Flue, flue burner is connected with the converter fume road, air blower, institute are provided with the floss hole in the converter fume road
State flue burner and be connected with waste-heat oven assembly, the waste-heat oven assembly is connected to storage heater and sack cleaner, institute
State storage heater and be connected with Turbo-generator Set, the sack cleaner is connected with air-introduced machine, and the air-introduced machine is connected with chimney, institute
The equal and external controlling switch of air blower, flue burner, waste-heat oven assembly, storage heater, air-introduced machine, Turbo-generator Set is stated to connect
Connect.
Preferably, the waste-heat oven assembly is set using double pressures.
Preferably, the cloth bag on the sack cleaner is detachable.
The utility model proposes a kind of converter fume excess air dry process TRT, beneficial effect is：This
The utility model mainly coal gas according to caused by converter, sets air blower at converter fume road, and the blow rate required contains coal gas with smoke evacuation
Amount matches, and ensures that coal gas fully burns, after by waste-heat oven assembly produce saturated vapor, waste-heat oven assembly is set using double pressures
Put, carry deoxygenation function, due to the periodicity of converter fume gas, steam caused by waste-heat oven is also periodicity, utilizes storage heater
Steam is adjusted, quantity of steam is evenly supplied as far as possible, the smoke evacuation work feed bag dust collector dedusting of waste-heat oven assembly, rear emptying, the iron of recovery
Powder, recycle；Caused saturated vapor send Turbo-generator Set generating etc., the increase of the utility model utilization, does not conform to
The waste of lattice coal gas emptying, be advantageous to environmental protection, no water loss, save gas chamber and water treatment system, be advantageous to iron powder
Recycle.It can realize that a subthermal energy is comprehensive at utmost using heat caused by waste heat caused by steelmaking converter and gas-fired
Close and utilize, save fume treatment cooling water, be advantageous to recycling iron powder, for generating electricity, waste-heat oven smoke evacuation is returned through sack cleaner
Iron powder is received, is emptied after smoke evacuation dust-laden is up to standard.
