Description
Technical field
The utility model belongs to steel rolling field gas generator system, the high blast gasification system of a kind of specifically high wind-warm syndrome.
Background technology
The atmospheric fixed bed gas-producer gasification system generally adopts the saturated air of normal temperature air and vapor mixing as vaporized chemical, saturation air temperature is about 50-65 ℃, and when reaction in furnace, vaporized chemical need be heated once more, consume a large amount of heat of reaction during this time, increased energy consumption.
The utility model content
The utility model purpose provides and a kind ofly cuts down the consumption of energy, the high blast gasification system of high wind-warm syndrome of save energy.
For achieving the above object, the utility model adopts following technical scheme:
The high blast gasification system of high wind-warm syndrome, comprise producer gas generator, air input unit, high-temp waste gas pipeline, steam-pipe, it is characterized in that, described air input unit successively with steam-pipe, high-temp waste gas pipeline, producer gas generator pipe connection, described air input unit and high-temp waste gas pipeline junction are provided with interchanger.
Further, described air input unit comprises air blower, variable valve, vacuum breaker, and described air blower, variable valve, vacuum breaker be pipe connection successively.
The beneficial effects of the utility model are: can cut down the consumption of energy, save energy is example with the process furnace of 150t/h heating efficiency, saves standard coal 22.629t/d every day.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1 producer gas generator, 2 air input units, 3 steam-pipes, 4 high-temp waste gas pipelines, 5 interchanger, 6 air blower, 7 variable valve, 8 vacuum breaker, 9 chimneys.
Embodiment
As shown in Figure 1, the high blast gasification system of high wind-warm syndrome, comprise producer gas generator 1, air input unit 2, high-temp waste gas pipeline 4, steam-pipe 3, wherein, described air input unit 2 successively with steam-pipe 3, high-temp waste gas pipeline 4, producer gas generator 1 pipe connection, described air input unit 2 is provided with interchanger 5 with high-temp waste gas pipeline 4 junctions; Described air input unit 2 comprises air blower 6, variable valve 7, vacuum breaker 8, and described air blower 6, variable valve 7, vacuum breaker 8 be pipe connection successively.
Described high-temp waste gas pipeline 4 one ends connect process furnace, and the other end connects chimney 9.
The high blast vaporized chemical of the high wind-warm syndrome of this process using gasifies, 190-220 ℃ the air that high wind-warm syndrome is carried out heat exchange from the air preheater and the stack gases of heater for rolling steel flue is sent to the vaporized chemical that forms 170-180 ℃ after the vapor mixing and participates in gasification in the producer gas generator.Gasification intensity improves 27.6-38.2%.The heat of ton steel billet consumption is the 1.38GJ/t steel billet.Reduce heat exhaustion 14.29%, save the 0.183GJ/t steel billet than normal process furnace heat exhaustion index, the ton steel billet is saved the 6.29kg standard coal.Process furnace with the 150t/h heating efficiency is an example, saves standard coal 22.629t/d every day.
