Description
Technical field
The present invention relates to a kind of heater, particularly relate to a kind of microwave, electric hybrid heating device.
Background technology
Heating using microwave is a kind of Novel heating mode by material self dielectric loss and self-heating in microwave field, except can making material Fast Heating and heating up, also has and improves reaction speed, improves reacting finisheding degree, reduces the non-thermal effects such as by-products content.
Therefore, can material by heating using microwave, relevant with the dielectric properties of material.But the dielectric properties of partial material can change with reaction temperature, the change of the material density of course of reaction, composition transfer and changing.Such as, in powder metallurgy, the density of powder blank increases fast in microwave sintering process, but often when solid density reaches 95-99%, the dielectric properties of blank decline.And due to microwave be by self dielectric loss self-heating, produce heat reduce, reaction temperature be difficult to rise even decline, final blank is difficult to realize complete densification sintering.And for example Mn oxide reduction, because Mn oxide is multivalent state compound, its absorbing property is different, in reduction process, with the composition transfer of reduction intermediate product, its wave-sucking performance produces respective change, causes the intensification ability of material to occur the situation that quick rising stagnates again.
Microwave, electric Hybrid Heating, both can retain the advantage of heating using microwave, can make up again microwave temperature when some low dielectric situation application and be difficult to the shortcoming keeping or rise.The implementation of existing microwave, electric Hybrid Heating equipment has two kinds, wherein one is wound around electrical heating components and parts on ceramic boiler tube, electrical heating components and parts outer wrapping insulation material, insulation material skin is metal body of heater, and microwave heating system is installed on metal body of heater.The Hybrid Heating that this kind of mode realizes, because electrical heating components and parts are in microwave field, in Hybrid Heating process, electrical heating components and parts serve the effect of microwave antenna, microwave outwards can be derived formation microwave from leakage, cause environmental pollution; In addition, the microwave of leakage can not be used for heating material, reduces the service efficiency of microwave.Another kind of microwave, electric Hybrid Heating mode are as mentioned by Chinese patent CN103105060B, CN102353254B, kiln section is divided to realize by heating using microwave and electrical heating, between two kiln sections adopt press down wave plate isolate, avoid microwave enter electrical heating kiln section to electrical heating components and parts produce interference reveal microwave.But this kind of implementation is suitable only for the serialization such as pushed bat kiln, roller kilns equipment, need to increase equipment size and equipment investment in intermittent equipment.
Summary of the invention
