Abstract
The utility model discloses a kind of divider to be connected with pipeline between blast furnace, the second valve is established between divider and blast furnace, coal injection pipe between divider and blast furnace is provided with coal jetting branch near divider one end, coal jetting branch is provided with the first valve, coal jetting branch is connected with coal-storage pot, is provided with the 3rd valve between divider and coal jetting branch.The coal dust of releasing all is collected in coal-storage pot, which saves coal dust, additionally reduce pollution on the environment, improve the operating environment of workman.
Description
Technical field
The utility model relates to a kind of coal powder collection device.
Background technology
World's ironmaking industry is faced with that coke oven is aging, coking coal is short and the problem such as production environment deterioration, with regard to China, and coal resources relative abundance, but coking coal resource is poorer.Along with the increase of consumption, coking coal resource is day by day in short supply.From the angle of the strategy of sustainable development of environment protection and coal resources Appropriate application, the developing into address these problems of furnace coal spraying technology provides cost-effective approach.Pulverized coal injection in blast furnace can save a large amount of coke, reduces production cost, alleviates the contradiction of coking coal shortage, is more conducive to environmental protect.
Coal dust is to leaving air port oxidation zone after entering air port belly pipe, and the residence time is very of short duration, and only less than the time of 1.2 seconds, the coal dust entering blast furnace during this period of time must complete intensification, decompose and burning.Due to bad weather or coal dust humidity, cause coal dust to carry not smooth, burn insufficient, very easily cause coal spraying pipeline to block.
Now widely used coal powder injection stands in the demand that next coal powder injection station of normal circumstances can meet or many blast furnace injection coals, pulverized coal preparation system when coal powder injection station breaks down, coal spraying pipeline blocking or generation blast furnace block up rifle, cannot meet causing coal powder injection station the continuous winding-up of responsible blast furnace, affect production direct motion and the production cost of blast furnace, the coal dust of releasing in pipeline when processing dredging coal spraying pipeline has all been put into ground, rinse with water subsequently, or directly sweep and clean out, both very large pollution was caused to environment, a large amount of coal dust is caused again to lose, be unfavorable for cost efficiency, coal powder collection becomes urgent problem.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, the coal powder collection device of low cost of manufacture, effectively can be got up by the coal powder collection that dredging coal spraying pipeline is released, economize on resources, improve operating environment.
The utility model realizes above-mentioned purpose by the following technical solutions: coal powder collection device, the divider comprising coal bunker and be connected with coal bunker, between divider with blast furnace, pipeline is connected, the second valve is established between divider and blast furnace, coal injection pipe between divider and blast furnace is provided with coal jetting branch near divider one end, coal jetting branch is provided with the first valve, and coal jetting branch is connected with coal-storage pot.
The 3rd valve is provided with between divider and coal jetting branch.
The utility model of technique scheme is adopted to have structure simple; make and be easy to advantage; the coal dust that dredging coal spraying pipeline is released effectively is collected; both environment had been protected not contaminated; improve the operating environment of workman; again save resource, be conducive to cost efficiency, the call that response national energy-saving reduces discharging.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, coal powder collection device, the divider 2 comprising coal bunker 1 and be connected with coal bunker 1, between divider 2 with blast furnace 3, pipeline is connected, establish the second valve 8 between divider and blast furnace, the coal injection pipe 5 between divider and blast furnace is provided with coal jetting branch 6 near divider one end, and coal jetting branch is provided with the first valve 7, coal jetting branch is connected with coal-storage pot 4, is provided with the 3rd valve 9 between divider and coal jetting branch 6.
During coal spraying pipeline normal operation coal powder injection, close the first valve 7 on coal jetting branch, open the second valve 8, the 3rd valve 9; There is stifled rifle or coal spraying pipeline blocking in blast furnace, closing the 3rd valve, opening the first valve and the second valve, being passed into by the coal dust in coal injection pipe in coal-storage pot and collecting recycling when processing dredging pipeline.The coal dust of releasing all is collected in coal-storage pot, which saves coal dust, additionally reduce pollution on the environment, improve the operating environment of workman.
