Abstract
The invention discloses a rotary kiln for producing lime through calcination by using an electric heating device. The rotary kiln comprises a rotary kiln body and is characterized in that the electric heating device is arranged in the rotary kiln body and is arranged at the calcining zone of the rotary kiln; the electric heating device consists of a heating rod circular pipe support, a support sleeve, a high-temperature-resistant tray, circular disc supports, heating rods, a conductor and insulating sleeves, the heating rods are fixedly arranged on the circular disc supports, the circular disc supports are fixedly arranged on the heating rod circular pipe support and the support sleeve, the high-temperature-resistant tray is arranged in parallel with one circular disc support which is arranged at a position adjacent to the end of kiln head, the conductor is connected with an external power supply, the insulating sleeves are sheathed at one ends of the heating rods adjacent to the kiln head, the temperature of the electric heating device is adjustable and the highest temperature is 1350 DEG C. The rotary kiln for producing lime through calcination by using the electric heating device has the advantages that the rotary kiln is energy-saving and environmental-friendly, the electric energy is fully utilized for heating, the energy is saved and high-purity, high-cleanness and high-whiteness lime products can be produced.
Description
Technical field
The present invention relates to rotary kiln, specifically a kind of rotary kiln of producing lime with electric heater unit calcining.
Background technology
Traditional lime production is to adopt the limestone kiln of burning coal, and this is that a kind of roughing type is produced, and not only production environment is severe, also large to the pollution of environment.Afterwards, though someone uses Sweet natural gas, coke gas etc. to do limestone kiln fuel, but fuel also can produce and pollute lime in combustion processes, make lime product of low quality, do not reach food grade and medical grade,, the carbonic acid gas producing in producing is not all fully utilized meanwhile yet, in the discharge of carbonic acid gas, ambient air is caused to huge pollution.
Summary of the invention
The object of the invention is to provide a kind of rotary kiln of producing lime with electric heater unit calcining.This rotary kiln utilizes electric heating calcining technology, and energy-conserving and environment-protective can be produced the lime product of high purity, high-cleanness, high whiteness.
The technical scheme that realizes the object of the invention is:
A rotary kiln of producing lime with electric heater unit calcining, comprises rotary kiln body, unlike the prior art: in rotary kiln body, be provided with electric heater unit, be arranged on the calcining zone of rotary kiln.
Described electric heater unit is comprised of heating rod pipe support, rack sleeve, high temperature resistant pallet, disc holder, heating rod, conductor and insulation thimble, heating rod is fixed on disc holder, disc holder is fixed on heating rod pipe support and rack sleeve, high temperature resistant pallet is arranged side by side with the disc holder being arranged near kiln hood one end, conductor is connected with external power, heating rod is set with insulation thimble near one end of kiln hood, and the temperature of electric heater unit is adjustable, and top temperature is 1350 ℃.
Advantage of the present invention is: energy-conserving and environment-protective, make full use of electric energy heating technique, and save the energy, can produce the lime product of high purity, high-cleanness, high whiteness.
