Medium-frequency heat accumulation-based dielectric barrier temperature field hearth and working method thereof

Abstract

The invention belongs to the technical field of combustors, and particularly relates to a medium-frequency heat accumulation-based dielectric barrier temperature field hearth and a working method thereof. The medium-frequency heat accumulation-based dielectric barrier temperature field hearth comprises a furnace frame, a cyclone feeding device arranged in the middle of the furnace frame, a first high-temperature-resistant heating pipe arranged on the cyclone feeding device, hearth walls arranged in front of the cyclone feeding device and tightly attached to the inner wall of the furnace frame, and a dielectric barrier plate arranged between the hearth walls. The first high-temperature-resistant heating pipe is fixed in the center of the cyclone feeding device; the first high-temperature-resistant heating pipe is a hollow pipe, and a first medium-frequency heating coil is fixed to the inner wall of the first high-temperature-resistant heating pipe. The device has the characteristics that the manufacturing cost and the production cost are saved, the reliability is high, the organic matter powder treatment capacity is large, the time is short, and rapid preheating and temperature rising can be realized.

Description

technical field [0001] The invention belongs to the technical field of burners, and in particular relates to a dielectric barrier temperature field furnace based on intermediate frequency heat gathering and a working method thereof. Background technique [0002] At present, the technology used for thermal cracking of organic matter is generally anaerobic cracking technology. Since it is a natural heat source plus anaerobic cracking, a large stacker and long-term natural passive heat accumulation are required to complete the process of anaerobic cracking of organic matter. However, the disadvantage of the above method is that static thermal cracking is used, the weight of the organic matter is less, the time is long (generally the anaerobic static thermal cracking time is 5-6 hours), and the equipment processing cost is high. [0003] In view of the above problems, high temperature plasma dynamic thermal field technology can be used to solve them. However, there are also pr...
