Description
Technical field
The utility model relates to a kind of axial blower and blows energy-conservation device, especially blast furnace in metallurgical industry axial blower air-supply arrangement, belongs to blast furnace in metallurgical industry blower equipment technical field.
Background technology
Metallurgy industry; hotblast stove is one of important equipment of blast furnace ironmaking; owing to axial blower has the advantages that air quantity is big, blast is high; blast furnace blowing engine adopts axial blower mostly, and gas blower, in air-supply process, obviously also has the ability to undertake load sometimes; but software is automatically protected and is opened anti-asthma valve and leak informaton; cause blower fan pressure of air supply not reach the requirement of blast furnace, waste a large amount of electric energy, manufacture a large amount of noises.
Practical novel content
The utility model object is to provide a kind of axial blower and blows energy-conservation device, and the little anti-asthma valve that a precision in parallel is higher on big anti-asthma valve, it is possible to meticulousr regulates anti-asthma aperture, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of axial blower is blown energy-conservation device, comprise blower fan, diffuse valve, leak informaton pipeline, air draft valve, cold air duct, big anti-asthma valve, little anti-asthma valve, regulate pipeline one, regulate pipeline two and hotblast stove, blower fan is connected with hotblast stove by cold air duct, leak informaton one end of pipeline is connected with cold air duct, leak informaton the other end of pipeline and atmosphere, the pipeline that leaks informaton is provided with and diffuses valve and air draft valve, one end of pipeline two is regulated to be connected with cold air duct, regulate the other end of pipeline two and the pipeline communication that leaks informaton, the tie point of pipeline two and the pipeline that leaks informaton is regulated to diffuse between valve and air draft valve, little anti-asthma valve is by regulating pipeline one in parallel with big anti-asthma valve.
Described blower fan is provided with gets air port.
Adopt the utility model, the little anti-asthma valve that a precision in parallel is higher on big anti-asthma valve, big anti-asthma valve plays the effect of coarse adjustment, little anti-asthma valve plays the effect of fine setting, the quiet leaf of blower fan can turn angle further down, can be meticulousr anti-asthma aperture be regulated, makes anti-asthma curve and actual operation curve more close, reaches energy-conservation object.
The beneficial effects of the utility model are: gas blower pressure of air supply can meet the requirement of blast furnace, and can saves energy, reduce noise.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: get air port 1, blower fan 2, diffuse valve 3, the pipeline 4 that leaks informaton, air draft valve 5, cold air duct 6, big anti-asthma valve 7, little anti-asthma valve 8, regulate pipeline 1, regulate pipeline 2 10, hotblast stove 11.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of axial blower is blown energy-conservation device, comprise blower fan 2, diffuse valve 3, leak informaton pipeline 4, air draft valve 5, cold air duct 6, big anti-asthma valve 7, little anti-asthma valve 8, regulate pipeline 1, regulate pipeline 2 10 and hotblast stove 11, blower fan 2 is connected with hotblast stove 11 by cold air duct 6, leak informaton one end of pipeline 4 is connected with cold air duct 6, leak informaton the other end of pipeline 4 and atmosphere, the pipeline 4 that leaks informaton is provided with and diffuses valve 3 and air draft valve 5, one end of pipeline 2 10 is regulated to be connected with cold air duct 6, pipeline 4 is connected the other end of adjustment pipeline 2 10 with leaking informaton, the tie point of pipeline 2 10 and the pipeline 4 that leaks informaton is regulated to diffuse between valve 3 and air draft valve 5, little anti-asthma valve 8 is by regulating pipeline 1 in parallel with big anti-asthma valve 7.
Described blower fan 2 is provided with gets air port 1.
In the present embodiment, blast furnace is 450 cubes of blast furnaces, and axial blower model is AV45, big anti-asthma valve 7 is for coarse adjustment, and little anti-asthma valve 8 is for fine setting, it is possible to meticulousr regulates anti-asthma aperture, make anti-asthma curve and actual operation curve more close, reach energy-conservation object. Through actual motion, electricity consumption every day 14.4 ten thousand degree, compared with background technology, can save electricity consumption 0.9 ten thousand degree every day, and ton iron about falls 5 degree, every monthly benefits about 13.5 ten thousand yuan expectation, it is contemplated that 34 days expenses of recouping capital outlay.
