Description
Technical field
The utility model relates to Iron And Steel Plant's blast furnace and reclaims the field with gas blower and coal gas overbottom pressure, is specifically related to a kind of online linkage system of gas blower tail gas energy recovery or blower fan unit and the online linked system of a kind of tail gas energy recovery gas turbine supercharging unit.
Background technology
Present domestic reaching in the world is mainly used in afterwards the use of driving generator for electricity generation with blast-furnace top gas recovery through the energy recycle device recovery, or blast-furnace top gas recovery is reduced the motor load use with compressor as coaxial unit afterwards through the energy recycle device recovery.The former can be converted into electric energy output through turbo-expander and generator with the blast furnace overbottom pressure that reclaims and utilize, and it is to reduce the load of phonomoter that the latter can replenish the blast furnace overbottom pressure that reclaims to compressor shaft through the mechanical energy that decompressor is converted into rotation.The function of these two kinds of structures all is that the blast furnace overbottom pressure can be recycled, but the performance that how much depends on former blast furnace of recovered energy, these two kinds of structures do not produce any change to original configuration of blast furnace.Secondly; The employed compressor of blast furnace generally all disposes two covers; These two the cover unit when blast furnace runs well one normally move as main frame; Reserve machine used when another broke down as main frame, so the user all need order two covers when ordering the complete unit of compressor at every turn, caused cost of investment to strengthen.
Summary of the invention
For overcoming the shortcoming that above-mentioned prior art exists, the utility model provides can practice thrift into a kind of, the online linkage system of gas blower tail gas energy recovery that safety is high.
The purpose of the utility model is to realize like this; The online linkage system of gas blower tail gas energy recovery; It is characterized in that: which comprises at least: blast furnace, main blower, phonomoter, supercharger, turbo; Supercharger is connected through the shaft coupling axle with turbo, realizes supercharger and turbo coaxial drive; Motor output shaft is connected with the main blower axle through behind the speed change mechanism; Main blower input air port communicates with air; Drive outside air through the negative pressure input aperture and get into main blower; To blast furnace air is provided, blast furnace is through blast furnace gas relief outlet and turbo input aperture end pipe connection, through exporting behind the turbo.
Described air-in is connected with the input port of main blower with the input port of supercharger separately through one road valve respectively and is connected; Supercharger output is connected with the input port of main blower through valve again; Through switching three valves; Make input air can be directly through main blower to the blast furnace input aperture, also can input air be sent into the input port of main blower after through the supercharger supercharging, then by being input to the blast furnace input aperture after the main blower compression.
Described air-in can directly communicate with the inlet end of main blower on the one hand; Main blower divides two-way; The valve of leading up to communicates with the blast furnace air inlet mouth, and another road is connected with the supercharger input port through valve, by communicating with the blast furnace air inlet mouth after the supercharger supercharging.Switch the mode that realizes that main blower output pressurized air gets into blast furnace through the valve of controlling two shunt.
The utility model has the advantages that: the utility model supercharging system can directly be replenished the overbottom pressure that reclaims to blast furnace with the pressurize mode, has reduced the waste between energy transformation.This unit can be used as the main frame life-time service, and because of this system consuming any energy source but can be the blast furnace supercharging not, its running cost will significantly reduce.
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
