Description

A kind of sequential pendulum model blowing device

Technical field

The utility model belongs to technical field of ferrous metallurgy, and in particular to a kind of sequential pendulum model blowing device and its control Method.

Background technology

Sintering process is the key link smelted iron in flow, and principle is by various powdery iron-containing raw materials, and supplying is fitted The fuel and flux of amount, add in suitable water, through mixing and making material that a series of physical occur on agglomerating plant after pelletizing Variation is learned, sintering is blocking, and the next step is carried out so as to be sent to blast furnace.

In order to reduce the coke ratio of blast furnace ironmaking and smelting cost, requirement of the blast furnace to sinter is often that high intensity and height are gone back Originality.In sintering circuit, generally require sinter that there is higher intensity, high finished product rate, the relatively low rate of return mine and relatively low Fuel consumption.The sinter of high intensity and high reproducibility consumes less coke in blast furnace ironmaking process, so as to reduce dioxy Change the discharge of carbon.In the long run consider, carbon dioxide discharge-reduction is required one of bottleneck as restriction development of iron ＆ steel industry.According to Related data introduction, sintering account for the 60% of industrial discharge total amount with blast furnace process CO2 emissions.Therefore, no matter from enterprise Industry reduces cost consideration and still considers from environmental protection angle, reduces sintering solid fuel this consumption ratio with reducing blast furnace burden Fuel ratio becomes the urgent need of ironmaking technology.

Under this overall situation, " the sintering charge level gaseous fuel injection technology " of Japanese JFE companies exploitation comes into being, former Reason is by blowing device, and injection is diluted to below combustible concentration lower limit above the pallet of a distance after ignition furnace Gaseous fuel makes its combustion heat supplying in sinter bed.The technology can reduce solid carbon dosage and CO in sinter production₂ Discharge capacity, simultaneously as the burning of gaseous fuel broadens high temperature bandwidth of the sinter bed in production, so that 1200 ~1400 DEG C of sinter temperature-time is extended, so that the intensity of sinter and 5~10mm porositys are had Effect is strengthened.

Combustion gas blowing device under conventional, prior art due to being the fixed pipe row of large area, is demonstrate,proved in long-term production Real storage is in following defect：

1st, large area pipe row each point spray orifice mass flow discrepancy：Under the prior art, large area pipe row by one end air inlet, it is porous go out Gas can so cause the injection hole injection flow close to inlet end more, and the injection hole flow away from inlet end is less, this is Fluid behaviour causes, and can not be solved by control valve.Once this occurs, charge level combustion gas injection in cover can be given Uniformity brings great negative effect.

2nd, there is injection blind area in fixed pipe row：Under the prior art, fixed pipe is come close to the both ends of injection tube, can not Open up injection hole, the intersection between being arranged material is thus formed two sections of injection tubes, always there are an area it is larger " injection is blind Zone " so not only reduces the uniformity of injection, and is easily negatively affected to the final product quality of sinter.

For above two defects, we have been subject to Optimal improvements to it on existing blowing device architecture basics, have tried hard to A kind of small area, revocable pendulum model blowing device are developed, and progress is organized to injection tube row by the method for timing control It is uniformly controlled, the injection non-uniform defect of effect is easily caused under the prior art in the hope of making up, reaching makes whole combustion gas injection auxiliary Sintering production processing line stable yields, natural labor, the purpose of excellent production.
