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
Be used for the carbon-calcining rotary kiln that aluminium electroloysis industry carbon calcination petroleum coke is used, present carbon-calcining rotary kiln two, tertiary-air pipe installation site do not adapt with a large amount of positions of overflowing of fugitive constituent, cause fugitive constituent to fail fully to burn or postponed the zero-time of burning, make intrinsic calcining tape backspacing, petroleum coke is failed by the calcining scheme calcining of the best, and this also is the relatively poor one of the main reasons of calcined coke physical and chemical index.Two, the unreasonable of tertiary-air pipe position also can be caused unnecessary energy waste, reduces the effective rate of utilization of the energy, and this also is the high major reason of at present most carbon element factory energy-output ratio.In addition, fuel and combustion air because of two, the not scientific matching that causes of tertiary-air pipe also can produce a large amount of tail gas, wherein contains the pernicious gases such as a large amount of nitrogen, sulphur compound and enters atmosphere, and environment is also caused serious pollution.
Summary of the invention
The present invention is exactly in order to solve the problems of the technologies described above, and provide a kind of carbon-calcining rotary kiln, purpose is that the present carbon-calcining rotary kiln two of solution, tertiary-air pipe are installed unreasonable, cause fugitive constituent to fail fully to burn or the delayed combustion zero-time, make intrinsic calcining tape backspacing, the 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 the Secondary Air feed system is to be made of Secondary Air blower fan, front secondary air channel and rear secondary air channel, front secondary air channel and rear secondary air channel all are to be made of 3-6 airduct, airduct is around the shape disposed at equal distance on the kiln body, and the air line distance between adjacent airduct is 1.2-1.5 rice; The tertiary air feed system is to be made of tertiary air blower fan, front tertiary-air pipe and rear tertiary-air pipe; Front tertiary-air pipe and rear tertiary-air pipe all are to be made of 3-6 airduct, and airduct is around the shape disposed at equal distance on the kiln body, and the air line distance between adjacent airduct is 1.2-1.5 rice.
The front end of above-mentioned Secondary Air feed system is 10-14 rice apart from kiln hood.
The rear end of above-mentioned tertiary air feed system is 14-18 rice apart from the kiln tail.
Angle between above-mentioned adjacent airduct is the 60-120 degree.
Above-mentioned kiln body is long to be 60-70 rice.
Since adopt said structure, so that the present invention has following advantage and effect:
The present invention changes carbon-calcining rotary kiln secondary air channel, word order that tertiary-air pipe is traditional into double-ring and arranges, guarantee secondary, tertiary air wind supply quantity, be conducive to take full advantage of volatile combustion, keep long 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, and position and the time that volatile matter overflows in the calcining petroleum coke process is adapted, and improves the calcined coke physical and chemical index, has solved that present carbon element industry energy-output ratio is large, the pollution emission environmental problem.The present invention realized the separate unit rotary kiln per hour produce the calcined petroleum coke of 15t, when normally producing, additive decrementation fuel not.
