Abstract
The utility model relates to an energy-saving and environmental protection coal injection device for a blastfurnace, which is composed of a coal dust distributor and coal injection pipelines, wherein one to fourteen coal injection pipelines are installed at the upper part of the coal powder distributor. A distributing bag is provided with a dredging device, wherein the dredging device is a threaded rod which is connected with the top part of the distributing bag. A T-piece (laterally punched) and a ball valve are arranged on a coal injection pipe below the distributing bag, wherein the T-piece is communicated with an annular pipe. The ball valve which is arranged at one end of the annular pipe is communicated with a compressed air pipeline; the other end of the annular pipe is communicated with the top part of a coal dust recovering tank; the lower part of the coal dust recovering tank is communicated with a coal dust blowing device. One end of the coal dust blowing device is communicated with the compressed air pipeline, and a blowing opening which is arranged at the other end of the coal dust blowing device is connected with a tuyere of the blastfurnace. The utility model realizes the recovery and utilization of coal dust. Therefore, the environmental sanitation of the blastfurnace is guaranteed, a water watching worker's labor intensity is reduced, the cost is reduced and a large amount of coal dust is saved.
Description
Technical field
The utility model is a kind of iron-smelting blast furnace coal powder blowing device.
Background technology
Iron-smelting blast furnace coal powder injection pipe causes stifled rifle easily, and solution can only be to airborne release, and when stifled rifle was frequent, every blast furnace was to a large amount of coal dusts of airborne release.Cause very big economic waste and environmental pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of iron-smelting blast furnace coal powder injection energy-saving environmental protection device, can be the outwards coal dust recycling of discharging of stifled rifle.
The utility model is to be realized by following technical scheme:
It is made up of pulverized coal distributor, coal powder injection pipeline, and pulverized coal distributor top is provided with 1-14 coal powder injection pipeline, and the coal powder injection pipe is provided with allocation packet and is connected with blast-furnace tuyere.Allocation packet is provided with dredger, and dredger is a threaded rod that is connected with the allocation packet top.Threaded rod manually rotates and inserts in the coal powder injection pipe, plays the mediation effect.Coal powder injection pipe under the allocation packet is provided with threeway (other dashing) and ball valve, a threeway and a ring pipe UNICOM.Ring pipe one end be provided with ball valve and with compressed air line UNICOM, the top UNICOM of the other end and coal dust withdrawing can, also be provided with safety valve and tensimeter on the coal dust withdrawing can, coal dust withdrawing can bottom and coal powder blowing device UNICOM, coal powder blowing device one end and compressed air line UNICOM.The other end is provided with the winding-up mouth and is connected with blast-furnace tuyere.Top in the coal dust withdrawing can is provided with funnel and can prevents the container internal resistance, falls in order to the coal ash condition.
The utility model inserts an environmental protection and saving device at the other place of dashing of allocation packet, when the spray gun that comes out from divider is blocked, open other towards ball valve, open the pressurized air ball valve simultaneously, coal dust is sent into the coal dust withdrawing can store,, open the coal powder blowing device ball valve when being stored into when a certain amount of, make coal dust enter coal powder blowing device, open the pressurized air ball valve again, coal dust is sprayed in the stove, so just realized the recycling of coal dust.Not only guaranteed the blast furnace environmental health, water tender's the labour intensity that become light, and reduced cost, saved a large amount of coal dusts.
