Abstract
The utility model provides an allocate device of fine coke in blast furnace jetting raw coal into, the square fine coke jar that sets up on blast furnace pulverized coal transport area, fine coke jar pass through the burnt powder tank of gas -force ash conveying union coupling, and burnt powder tank passes through the nitrogen gas pipe and links to each other with the nitrogen gas jar, is equipped with manual push -pull valve and unloading valve on the discharging pipe of fine coke jar lower part respectively, installs water jet equipment on the hank cage of fine coke jar discharging pipe below. The utility model discloses can replace former buggy to regard as blast furnace fuel injection the fine coke, realize that the wastes material of fine coke is recycled, not only can greatly reduce the blending cost, can reduce stock ground area in addition, avoid improving operation environment and air quality owing to the environmental pollution that the fine coke raise dust led to the fact.
Description
Technical field
This utility model belongs to ironmaking proportioner field, particularly relates to a kind of device allocating coke powder in blast furnace blowing raw coal into.
Background technology
Coking dry coke quenching produces substantial amounts of coke powder, and this part coke powder can not directly be transported to blast furnace as coke by-products and use as iron-smelting raw material.Therefore coke powder is always up as waste dump in stock ground, not only occupied ground, and puts the coke powder in stock ground aside as useless and very easily form substantial amounts of airborne dust, and the environment around severe contamination causes environmental protection index to exceed standard.
Summary of the invention
This utility model aims at the refuse reclamation of coke powder, reduces coal blending cost, reduces environmental pollution.
For this, the technical solution that this utility model is taked is:
A kind of blast furnace blowing raw coal is allocated into the device of coke powder, it is provided above coke powder tank at blast-furnace coal powder conveyer belt, coke powder tank connects coke powder tank car by pneumatic transporting ash pipe, coke powder tank car is connected with nitrogen pot by nitrogen tube, coke powder tank bottom discharge nozzle is respectively provided with hand operated gate valve and unloading valve, below coke powder tank discharge nozzle, cage is provided with water injector.
Described coke powder tank is arranged above with pressure release cloth bag.
The using method of the present invention and having the beneficial effect that
With mill, coke powder being milled into particle diameter-200 order coke powder fine powder more than 80%, coke powder fine powder, to coke powder tank place, is loaded in coke powder tank by airlift mechanism by automotive, allocates at coke powder and opens the airborne dust that water injector control blanking point produces in raw coal process.During each run coal bin fortune coal, starting coke powder tank, allocated into by coke powder fine powder in winding-up raw coal, coke powder fine powder allocation ratio accounts for the 3～5% of raw coal total amount, and scale is controlled by the push-pull valve on coke powder tank.
Coke powder can be replaced raw coal powder as blast furnace blowing fuel by this utility model, achieve the refuse reclamation of coke powder, not only can greatly reduce coal blending cost, and stock ground floor space can be reduced, avoid the environmental pollution owing to coke powder airborne dust causes, improve working environment and air quality.
Accompanying drawing explanation
Fig. 1 is the apparatus structure schematic diagram allocating coke powder in blast furnace blowing raw coal into.
In figure: auger 1, water injector 2, push-pull valve 3, coke powder tank 4, pressure release cloth bag 5, ash pipeline 6, unloading valve 7, auger motor 8, coal dust conveyer belt 9, coke powder tank car 10, nitrogen tube 11, nitrogen pot 12.
Detailed description of the invention
This utility model blast furnace blowing raw coal is allocated into the device of coke powder, one is set up with the coke powder tank 4 of pressure release cloth bag 5 above blast-furnace coal powder conveyer belt 9, coke powder tank 4 is connected to pneumatic transporting ash pipe 6, ash pipeline 6 other end connects coke powder tank car 10, coke powder tank car 10 is connected with nitrogen pot 12 by nitrogen tube 11, and is provided, by nitrogen pot 12, the strength that coke powder transports.Being respectively provided with hand operated gate valve 3 and unloading valve 7 on the bottom discharge nozzle of coke powder tank 4, the cage 1 below coke powder tank 4 discharge nozzle is provided with water injector 2, cage 1 is connected with the auger motor 8 being located at opposite side.
