Abstract
The invention discloses a rotary kiln in the field of aluminum-used anode production, and particularly relates to a carbon calcining rotary kiln which comprises a kiln body, a lining, a kiln head, a kiln tail, a secondary air supply system and a tertiary air supply system. The secondary air supply system comprises a secondary air fan, a front secondary air pipe and a rear secondary air pipe, the front secondary air pipe and the rear secondary air pipe comprise 3-6 air pipes respectively, the air pipes are circularly arranged on the kiln body equidistantly, the straight-line distance between each two adjacent air pipes is 1.2-1.5m, the tertiary air supply system is composed of a tertiary air fan, a front tertiary air pipe and a rear tertiary air pipe, the front tertiary air pipe and the rear tertiary air pipe are composed of 3-6 air pipes respectively, the air pipes are circularly arranged on the kiln body equidistantly, and the straight-line distance between each two adjacent air pipes is 1.2-1.5m. The carbon calcining rotary kiln is in favor of fully utilizing combustion of volatiles, maintaining a longer calcining zone and high temperature of the calcining zone and improving product quality of calcined coke, and energy consumption is lowered.
Description
Technical field
The present invention relates to a kind of rotary kiln of aluminium anode production field, particularly relate to a kind of carbon-calcining rotary kiln.
Background technology
For the carbon-calcining rotary kiln of aluminium electroloysis industry carbon calcination petroleum coke, the position that current carbon-calcining rotary kiln two, tertiary-air pipe installation site are not overflowed in a large number with fugitive constituent adapts, fugitive constituent is caused to fail Thorough combustion or be delayed the initial time of burning, make intrinsic calcining tape backspacing, petroleum coke fails to calcine by the calcining scheme of the best, and this is also the poor one of the main reasons of calcined coke physical and chemical index.Two, the unreasonable of tertiary-air pipe position also can cause unnecessary energy waste, reduces the effective rate of utilization of the energy, and this is also the major reason that carbon element factory's energy-output ratio is high mostly at present.In addition, fuel and combustion air because of two, tertiary-air pipe and the not scientific matching that causes also can produce a large amount of tail gas, wherein enter air containing a large amount of pernicious gases such as nitrogen, sulphur compound, serious pollution also caused to environment.
Summary of the invention
The present invention is exactly to solve the problems of the technologies described above, and a kind of carbon-calcining rotary kiln is provided, object be solve current carbon-calcining rotary kiln two, tertiary-air pipe is installed unreasonable, fugitive constituent is caused to fail Thorough combustion or delayed combustion initial time, make intrinsic calcining tape backspacing, calcined coke physical and chemical index is poor, the problem of energy resource consumption.
For solving above-mentioned practical problem, the present invention is achieved through the following technical solutions:
A kind of carbon-calcining rotary kiln, it comprises kiln body, liner, kiln hood, kiln tail, Secondary Air feed system, tertiary air feed system, wherein Secondary Air feed system is made up of Secondary Air blower fan, front secondary air channel and rear secondary air channel, front secondary air channel and rear secondary air channel are all be made up of 3-6 airduct, airduct is that the air line distance between adjacent airduct is 1.2-1.5 rice around shape disposed at equal distance on kiln body; Tertiary air feed system is made up of tertiary air blower fan, front tertiary-air pipe and rear tertiary-air pipe; Front tertiary-air pipe and rear tertiary-air pipe are all be made up of 3-6 airduct, and airduct is that the air line distance between adjacent airduct is 1.2-1.5 rice around shape disposed at equal distance on kiln body.
The front end distance kiln hood of above-mentioned Secondary Air feed system is 10-14 rice.
The rear end distance kiln tail of above-mentioned tertiary air feed system is 14-18 rice.
Angle between above-mentioned adjacent airduct is 60-120 degree.
Above-mentioned kiln body is long is 60-70 rice.
Owing to adopting said structure, tool of the present invention is had the following advantages and effect:
The present invention changes carbon-calcining rotary kiln secondary air channel, word order that tertiary-air pipe is traditional into double-ring arrangement, ensure secondary, tertiary air wind supply quantity, be conducive to making full use of volatile combustion, keep longer burning zone and high temperature thereof, improve the product quality of calcined coke; The installation site of secondary air channel, tertiary-air pipe is more reasonable, the position that in calcining petroleum coke process, volatile matter overflows was adapted with the time, improves calcined coke physical and chemical index, solve current carbon element industry energy-output ratio greatly, pollution emission environmental problem.Present invention achieves the calcined petroleum coke of separate unit rotary kiln production per hour 15t, when normally producing, not excessive fuel consumption.
