Method for arranging microwave emitters on outer peripheral surface of rotary kiln body

Abstract

The invention discloses a method for arranging microwave emitters on the outer peripheral surface of a rotary kiln body, which comprises the following steps of: arranging a plurality of wave feed ports on the outer peripheral surface of a cylindrical kiln body, mounting microwave generators capable of rotating along with the kiln body on the wave feed ports, and arranging a power receiving device capable of receiving an external power supply on the kiln body under the working condition that the kiln body rotates, and the power line is communicated with the power receiving device and the microwave generator. A plurality of wave feeding openings are formed in the peripheral face of the kiln body, and each wave feeding opening independently occupies one section of the kiln body on the periphery of the cylindrical kiln body. The microwave generator has the advantages that compared with a traditional wave feeding mode, complete sealing of the microwave generator and the wave feeding opening is achieved, the heat efficiency utilization rate of the microwave generator is remarkably improved, and meanwhile injury accidents caused by microwave leakage can be completely avoided; the directions of microwaves emitted by the microwave generators are not aligned and not intersected, microwave interference offset and ignition are avoided, and the microwave heat efficiency utilization rate can be further improved.

Description

technical field [0001] The invention relates to a method for arranging microwave emitters on the peripheral surface of a rotary kiln body, and belongs to the technical field of rotary kiln electric heating. Background technique [0002] With the development of microwave technology, its application has begun to expand to the field of rotary kiln heating to replace coal and other fuels for heat generation. However, due to the short application time of microwave in the field of rotary kiln, the microwave rotary kiln that has been developed and formed has unreasonable position setting, power connection mode and line direction of the microwave generator and its power line, power receiving device involved in the kiln body , Unreliable, and not simple, resulting in low thermal efficiency utilization of microwave rotary kiln, unsafe electricity consumption, and high processing and maintenance costs. [0003] By searching, obtain the following patent documents closest to the present...
