Microwave heating furnace core

Abstract

The invention discloses a microwave heating furnace core comprising a furnace core shell. A heat-resisting heat insulation layer is arranged in the furnace core shell, the heat-resisting heat insulation layer is internally provided with a water heat insulation tank with a hollow inner cavity, and the water heat insulation tank is a rectangular and ring-shaped sealing tank. An opening of the hollowinner cavity of the water heat insulation tank is consistent with an opening of the furnace core shell in direction, a water outlet pipe is arranged at the upper end of the water heat insulation tank, and a water inlet pipe is arranged at the lower end of the water heat insulation tank. A plurality of heat exchange pipes are arranged in the hollow inner cavity in the vertical direction, the two ends of the heat exchange pipes communicate with the water heat insulation tank, and heat conducting plates are arranged on the positions, on the two sides of the heat exchange pipes, of the hollow inner cavity. A plate-shaped heat-insulation cotton layer and a shell cover plate are arranged on the front side and the rear side of the furnace core shell, and a plurality of evenly-distributed microwave generators are arranged on the positions, corresponding to the heat conducting plates, of the shell cover plate and guide microwaves onto the heat conducting plates through magnetic control pipes to enable the heat conducting plates to release heat energy.

Description

technical field [0001] The invention relates to the technical field of heating furnaces, in particular to a microwave heating furnace core. Background technique [0002] At present, known heating stoves have coal-burning stoves, oil-fired stoves, gas stoves and resistance wire stoves. The thermal conductivity of existing heating methods of various energy sources is: 30% for coal furnace, 55% for coal gas, and 55-63% for electric heating wire furnace. As we all know, whether it is firewood, coal, oil, or liquefied gas, all kinds of furnaces of different sizes, as well as modern electric furnaces, gradually heat the water body from the outside to the inside through heat conduction and heat radiation. During the process, the metal furnace pipe container, furnace wall and surrounding air are heated at the same time, and the heat loss is relatively large. However, the long-term use of combustion heating not only consumes a large amount of valuable coal resources, but also has s...
