Description
Technical field
The invention belongs to microwave heating technique field, be specifically related to a kind of continuous-type microwave heating Double shaft stirring device.
Background technology
Microwave energy, as a kind of novel heat resource form, is more and more applied to heating art, such as: chemical industry, metallurgy, medicine, food, papermaking, timber etc.Its effect played comprises: sterilizing, drying, destructive distillation, sintering, roasting etc.Tradition heating furnace used adopts resistance wire, Elema, graphite etc. as heater element, after burner hearth is heated, by radiation and conduction, material ecto-entad is heated, belong to external heating mode, heat time is long, energy consumption is large, it is uneven to heat, and affects properties of product.
The process of heating using microwave is briefly dielectric material own loss energy of electromagnetic field and self-heating, it does not need heat transfer from outward appearance to inner essence, belong to interior mode of heating, heating is rapid, even, does not have thermograde, in heating using microwave, microwave energy can only by polar molecule Absorption of Medium heat-dissipating, air in heating clamber and cell therefor all can not generate heat, and also do not pass through other intermediate conversion links, therefore except a small amount of loss almost without other losses.Than general conventional heating power saving about 30% ~ 50%, production environment is also obviously improved.
For heating using microwave, the ability of its Absorption of Medium microwave energy is relevant with the complex dielectric permittivity of this material, namely fissipation factor is larger, absorb the ability of microwave stronger, therefore heating using microwave has strong selective, that is: microwave is suitable for heating microwave absorbing material, as: SiC, carbon, ferrite, water, aluminium nitride, part semiconductor pottery and cermet, metal fine powder, etc., microwave then directly can not heat block metal material, because metallic reflection microwave; Microwave is also difficult to heat a lot of insulating material, such as: glass, plastics (as: polytetrafluoroethylene (PTFE), polyethylene, polypropylene, polystyrene etc.), quartz and part ceramic material, because these materials are " transparent " to microwave, they do not absorb or less microwave energy absorbing; Microwave is more difficult to heat most gas and liquid, because they are higher to " transparency " of microwave, the efficiency of heating surface therefore for these material microwaves can be very low.
In addition, different according to the rate of heat addition of heating using microwave opposed polarity molecular media, the quality of material can be improved.Such as, some impurity (such as sulphur, phosphorus and other alkali metal) in coal, different from the rate of heat addition of coal, microwave treatment can be used for reducing these impurity and not oxidized coal, so the application of heating using microwave, can obtain that energy consumption is low, the measured effect of matter, the thermal inertia of heating using microwave is minimum.If adapted microcomputer controls, be then particularly suitable for the Automated condtrol of heating process heating process.Operating cost can be reduced.
In heating using microwave, drying, produce without waste water, waste gas, refuse, also radiationless legacy exists, its microwave leakage also guarantees the safety standard being significantly less than country's formulation, it is a kind of fool proof harmless new and high technology, traditional heating process device therefor, has: rotary kiln, tunnel cave, electrothermal furnace, fluid bed etc.These heating furnaces need corollary equipment, and it is large to take up room.
