Abstract
A rotary kiln coal dust plasma ignition device with flow rotating/equalizing function belongs to a coal dust kiln ignition device. The rotary kiln coal dust plasma ignition device is composed of the following components: a connecting flange, a flow equalizer outer pipe, a plasma arc generator, a plasma arc radiation area and a plasma thermal cracking reaction combustor. The coal dust inlet segment of the plasma thermal cracking reaction combustor is additionally provided with 8-16 coal dust flow rotating/equalizing blades. The rotary kiln coal dust plasma ignition device has the following advantages: simple structure, high reliability in use, capability of gasifying coal dust in ignition, sufficient combustion, and high operation performance.
Description
Technical field
The utility model relates to a kind of coal dust rotary kiln plasma ignition device, mainly be the CONCENTRATION DISTRIBUTION of coal dust in the plasma-arc regional extent in the control coal dust rotary kiln plasma ignition, this is vital for the igniting under the cold kiln state of revolution coal dust kiln plasma.
Background technology
" boiler, kiln adopt the ionic arc igniting " is that budget of the Central Committee investment ten big intermediate item one of are supported.Using this device igniting and combustion-supporting purpose is the fuel oil of conserve expensive, replace oil with coal igniting and combustion-supporting.The traditional sparking mode of kiln is with more than fuel oil elder generation heating furnace to 800 degree, drops into coal dust firing then, nearly ten million ton in annual coal dust rotary kiln baking kiln, igniting, steady burnup oil.When using coal dust rotary kiln plasma ignition device, since coal dust for the corner segments of powder pipeline, straight section with vertical, level is different, therefore, cause the distribution, the concentration that enter coal dust in the ionic arc zone to be difficult to control, greatly have influence on the heat cracking reaction of coal dust the best in the plasma radiation zone, causing discharging dust increases, and the igniting power consumption strengthens.
Summary of the invention
In order to overcome the problem that exists on the prior art, the utility model provides a kind of kiln coal dust plasma-arc igniter with coal powder cyclone, flow equalizing function.Coal powder density, pulverized coal flow state that this device can make the pulverized coal flow of different powder inlet pipe road directions, position, pipe diameter enter in the plasma-arc radiation areas are controlled and unified, can fully play the plasma-arc radiation areas to the lighting of pulverized coal flow, can make the mixed coal powder that enters the thermal cracking gasification device obtain sufficient thermal cracking gasification.
The technical scheme that its technical problem that solves the utility model adopts is: the kiln coal dust plasma ignition device with eddy flow flow equalizing function is made up of adpting flange, current equalizer outer tube, plasma-arc generator, plasma-arc radiation area and plasma heat cracking reaction burner, advances the coal dust section at plasma heat cracking reaction burner and installs coal powder cyclone current-sharing blade additional.
The utility model is simple in structure, uses reliably, and coal dust is gasified, and fully burning, and transaction capabilities is good.
Description of drawings
Fig. 1 is the kiln coal dust plasma ignition device general structure schematic diagram with eddy flow flow equalizing function;
Fig. 2 is the side direction view of Fig. 1.
Piece number explanation among the figure:
1, adpting flange, 2, coal powder cyclone current-sharing blade, 3, current equalizer outer tube, 4, plasma-arc generator, 5, plasma-arc radiation area, 6, plasma heat cracking reaction burner.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.A kind of kiln coal dust plasma ignition device with eddy flow flow equalizing function, described device is made up of adpting flange 1, current equalizer outer tube 3, plasma-arc generator 4, plasma-arc radiation area 5 and plasma heat cracking reaction burner 6, advances the coal dust section at plasma heat cracking reaction burner 6 and installs coal powder cyclone current-sharing blade 2 additional.It is the 8-16 sheet in even eddy flow current-sharing blade 2 quantity of arranging of powder inlet pipe inwall hoop that described plasma heat cracking reaction burner 6 advances the coal dust section.
During operation, regardless of coming powder pipeline corner direction, a wind coal dust carries down at blast and enters from the direction of arrow: adpting flange 1, in the current equalizer outer tube 3, strike coal powder cyclone current-sharing blade 2 when entering, under its guiding, form certain direction of rotation, the pulverized coal flow of certain distribution density enters into plasma-arc generator 4, swing and the distribution density pulverized coal flow determined by design parameter are able to best thermal cracking decomposition condition in plasma-arc radiation area 5, coal dust is by further thermal cracking in plasma heat cracking reaction burner 6, fuel gas reaches more than 30%, make coal dust be able to gasification, and combustion, reach the purpose of kiln plasma non-oil ignition
