Description

A kind of rotary kiln burner
Technical field
The utility model is applied in the calcining production of rotary kiln active lime, and in particular to a kind of flammable powder and combustible gas The burner of body co-fire.
Background technology
The fuel that calcined by rotary kiln active lime uses at present has coal dust, blast furnace gas, coal gas of converter, coke-stove gas, day Right gas etc. is a variety of, and burner has gas burner, solid powder burner and atomized liquid burner.Application No. 200720044242.6 patent《Five-channel coal-powder combustor for cement rotary kiln》In disclose a kind of burner, the burner For the burning of coal dust, five passages have four passages to be used to divulge information, and a passage is used to be passed through coal dust.Application No. 201020657983.3 patent《A kind of six channel rotational-flow stable-flame stepless regulation multi-fuel combustors》In disclose a kind of six passages Burner, the burner is used for coal dust, combustion gas multifuel combustion or coal dust, combustion gas single fire uses.
The main component of calcium carbide factory calcium carbide stove exhaust is CO, reaches more than 80%, also a small amount of CO2、H2、N2Deng, Calcium carbide tail gas is discharged into air after ignited often as waste gas, so causes energy waste.Semi-coke powder is also calcium carbide life Byproduct in production, it is the dedusting ash collected by dust-precipitator, is added to after generally being transported by automobile in coal cinder, recycles, But because its fineness below 200 mesh, good fluidity, is being transported and dust from flying is formed during entrucking, polluting environment.
In order to make full use of the byproduct calcium carbide tail gas and semi-coke powder that calcium carbide produces, the utility model provides a kind of flammable The burner of powder and fuel gas co-fire, calcium carbide tail gas and semi-coke powder by pipeline be sent in burner and burnt, and is used In on the rotary kiln of active lime calcining production, that is, solve the problems, such as energy waste, also solve fine powder problem of environmental pollution.
The content of the invention
Problem is recycled in order to solve calcium carbide tail gas and semi-coke powder, the utility model provides a kind of flammable powder and can The burner of combustion gas body co-fire.
Technical scheme is used by the utility model:
Burner uses five passages, and from center, outwards respectively center wind duct, semi-coke powder passage, calcium carbide tail gas lead to Road, air swirl wind passage, air axle stream wind passage.Center wind duct is designed using clear opening, realizes that straight line is blown;Semi-coke powder Passage, calcium carbide tail gas passage are provided with swirl vane in burner head, realize that semi-coke powder and calcium carbide tail gas spray burner for rotation Turn shape, to realize the combustion even of semi-coke powder and calcium carbide tail gas;Air swirl wind passage also is provided with eddy flow leaf in burner head Piece, realize that air rotary sprays burner, ensure that air mixes with calcium carbide tail gas and the uniform of semi-coke powder, so as to ensure calcium carbide Tail gas and semi-coke powder homogenous combustion;Air axle stream wind passage is designed using clear opening, realizes the cladding to burner flame shape, Control the length of flame.
Further, to ensure that igniting is convenient, increase clear opening ignition channel in center wind duct, form six passages. Ignition channel is passed through coal gas or other fuel gas, is lighted a fire using electronic ignition or torch, a small flare is formed, for lighting Calcium carbide tail gas and semi-coke powder, after calcium carbide tail gas and blue powdered carbon combustion, the fuel gas of ignition channel can be closed.
The beneficial effects of the utility model are:
The utility model realizes the recycling burning of semi-coke powder and calcium carbide tail gas, and the design of swirl vane ensure that orchid Powdered carbon and calcium carbide tail gas fully contact with air, realize abundant burning, have accomplished making full use of for byproduct, both saved The energy, the production cost of lime is reduced again.
Brief description of the drawings
Fig. 1 is the utility model Five-channel burner structure schematic diagram;
Fig. 2 is the channel burner structural representation of the utility model six;
Wherein, 1- center wind ducts 2- semi-cokes powder passage 3- calcium carbide tail gas passage 4- Whirl deposite tank passage 5- axle streams Wind passage 6- ignition channels.
Embodiment
Embodiment 1
Fig. 1 is the utility model Five-channel burner structure schematic diagram, burner totally five passages, is outwards distinguished from center Centered on wind passage 1, semi-coke powder passage 2, calcium carbide tail gas passage 3, Whirl deposite tank passage 4, axle stream wind passage 5.Center wind duct 1 is adopted Designed with clear opening, be passed through air, realize that straight line is blown;Semi-coke powder passage 2 and calcium carbide tail gas passage 3 each lead into semi-coke powder and Calcium carbide tail gas, the two passages are provided with swirl vane in burner head, and such semi-coke powder and calcium carbide tail gas can be sprayed with rotary Go out burner, realize the combustion even of semi-coke powder and calcium carbide tail gas;Whirl deposite tank passage 5 is passed through air, is also set in burner head There is swirl vane, realize that air rotary sprays burner, ensure that air mixes with calcium carbide tail gas and the uniform of semi-coke powder, so as to Ensure calcium carbide tail gas and semi-coke powder homogenous combustion;Axle stream wind passage 5 is designed using clear opening, is passed through air, is realized to burner The cladding of flame profile, to control the length of flame.
The present embodiment realizes the recycling of semi-coke powder and calcium carbide tail gas, the design of swirl vane ensure that semi-coke powder and Calcium carbide tail gas fully contacts with air, realizes abundant burning, has accomplished the recycling of calcium carbide factory's byproduct, both saved The energy, the production cost of lime is reduced again.
Embodiment 2
Fig. 2 is the channel burner structural representation of the utility model six, and burner totally six passages, are that embodiment 1 is burnt The improvement of device, to ensure that igniting is convenient, the increase ignition channel 6 in center wind duct 1.Ignition channel 6 be passed through coal gas or other Fuel gas, lighted a fire using electronic ignition or torch, form a small flare, for lighting calcium carbide tail gas and semi-coke powder, work as electricity After stone tail gas and blue powdered carbon combustion, the fuel gas of ignition channel can be closed.
The present embodiment realizes igniting conveniently, improves efficiency on the basis of embodiment 1.
