Abstract
The utility model belongs to the technical field of lead smelting, in particular to an oxygen supply device for oxygen-enriched air smelting in lead blast furnace. An oxygen storage tank is communicated with the wind pipe of a Roots blower for feeding the blast furnace via an oxygen hose; the oxygen in the oxygen pipeline and air from the Roots blower are mixed evenly in the wind pipe and then fed to the blast furnace; a silicon brass oil-free valve is arranged on the oxygen hose to feed oxygen stably and evenly, thus greatly improving the furnace capacity and perfecting relevant economic index.
Description
Technical field
The utility model belongs to plumbous technical field of smelting, relates in particular to a kind of apparatus of oxygen supply of lead blowing-furnace oxygen-rich smelting process.
Background technology
Implement lead blowing-furnace oxygen-rich smelting process, the treatment capacity of raising stove that can be is by a relatively large margin also improved the correlation technique economic target, but the key point of implementing this technology is the assurance of oxygen concn, the oxygen concn frequent fluctuation not only can not make this technology normally be carried out, and also might cause such as comparatively serious negative impacts such as stove ore deposit unstability, index deteriorations.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of treatment capacity of raising stove by a relatively large margin is provided and improves the apparatus of oxygen supply of guaranteeing the normal lead blowing-furnace oxygen-rich smelting process of implementing of oxygen-enriched air smelting technology of correlation technique economic target.
Technical solution adopted in the utility model is: by the oxygen channel connection oxygen storage tank is arranged at roots blower on the air fed pipeline of blast furnace.Oxygen in the oxygen channel and in roots blower the air of stable supplying, in airduct, send into blast furnace behind the uniform mixing, oxygen supply pipeline is provided with silicon brass does not have the fuel tap door.
Oxygen storage tank is connected by the oxygen installation of inlet pipe with the oxygen that produces, tensimeter and safety valve are installed on oxygen storage tank, set certain value according to specific requirement, safety valve is opened automatically when pressure is higher than this definite value, oxygen storage tank is connected oxygen channel by escape pipe, also has hand-hole and the wash water valve of making oxygen storage tank maintenance usefulness on oxygen storage tank.
Effective effect of the present utility model is: can realize the uniform and stable supply of oxygen, the treatment capacity of raising stove is by a relatively large margin also improved the correlation technique economic target.
Description of drawings
Fig. 1 is oxygen supply facility structure figure of the present utility model.
Fig. 2 is an oxygen storage tank structure iron of the present utility model.
Embodiment
As shown in Figure 1, 2, on blast furnace 10 air fed pipelines, oxygen storage tank 11 is arranged at roots blower 8 by the oxygen channel connection.
Oxygen in the oxygen channel and in roots blower the air of stable supplying in airduct 9, send into blast furnace 10 behind the uniform mixing, oxygen supply pipeline is provided with silicon brass does not have the fuel tap door.
Oxygen storage tank 11 is connected by the oxygen installation of inlet pipe 4 with the oxygen that produces, tensimeter 1 and safety valve 5 are installed on oxygen storage tank 11, set certain value according to specific requirement, safety valve 5 is opened automatically when pressure is higher than this definite value, oxygen storage tank 11 is connected oxygen channel by escape pipe 2, also is provided with hand-hole 6 and the wash water valve 7 of making oxygen storage tank maintenance usefulness on oxygen storage tank 11.Oxygen storage tank 11 is installed on the ground by support 3.
Oxygen that oxygen installation produces enters in the oxygen storage tank 11 from inlet pipe 4, and tensimeter 1 is set certain value according to specific requirement, and safety valve 5 is opened automatically when pressure is higher than this definite value, the oxygen emptying.Oxygen in the basin can stably enter into oxygen channel from escape pipe 2.Oxygen in the oxygen channel and in roots blower 8 fresh air of stable supplying, in airduct 9, send into blast furnace 10 behind the uniform mixing, make into the stove air oxygen concentration to reach the processing requirement value.
Between blast furnace and oxygen station, increase an oxygen storage tank, difference according to the different size stove requires to set different force value, the front and back of oxygen storage tank install special valve additional according to the suitable position of the different choice in actual production place, in order to adjust in good time.The concrete operations step: 1, the supply of oxygen should be carried out after 5 minutes at the roots blower air feed at least, should open the valve before the roots blower during air feed earlier, after open valve before the gas holder; 2, no matter which kind of reason causes the blast furnace blowing-out, before all must be with the valve closes before the gas holder, close the valve of closing behind the valve before the gas tank before the roots blower earlier.
