Description
Technical field
The present invention relates to a kind of system of Microwave Heating object, relate in particular to the system of utilizing Microwave Heating cottrell insulator, belong to heating using microwave applied technical field.
Background technology
In recent years, along with developing rapidly of economy, the boiler that metallurgical steel-smelting electric furnace and the raw coal of take are fuel increases a lot, the atmosphere pollution of these stove discharges causes very large harm to surrounding environment, yet reducing or reduce the main path that stove discharges pollutants is all kinds of device for abatement of smoke and dust that match with stove, so the performance of deduster and efficiency are to determine that a stove is to the work the mischief key point of degree of surrounding environment.
Efficiency of dust collection is high, energy consumption is low because having for cottrell, the large gas of the energy high exhaust gas volumn for the treatment of temperature, the features such as durable, convenient management, at industrial departments such as electric power, cement, metallurgy, coloured, chemical industry, light industry, electronics, machineries, obtain extensive use, in Air Pollution Control, brought into play very important effect.But when playing the dewfall that the temperature of the insulator dielectric insulator, porcelain insulator etc. of load-bearing insulating effect causes lower than flue gas dew point, the inner target of cottrell causes high-voltage breakdown or arcing, reduce dust-precipitator corona discharge power, and reasonably electric precipitator corona power is one of key factor guaranteeing electric cleaner safety, stable operation, the operation of corona discharge power low level can cause follow-up a series of production order to destroy.In order to guarantee seal, reason temperature is around not too low, occurs condensing water vapor, and make seal occur creepage short circuit phenomenon on its surface, destroy insulating properties, make operating voltage rise not get on, need incubator be set around at seal, make insulator temperature higher than 20～30 ℃ of gas dew points.The dew point that insulator box is warmed up to higher than medium is the necessary condition that electric cleaner puts into operation, and medium temperature is higher, and the heating-up time is longer, and electric cleaner waits for that the time of putting into operation is also longer.The problem of insulator box heating and thermal insulation has become the key issue that electric precipitation puts into operation at present.

Heating using microwave is different from conventional heating, and it does not need heat conduction from outward appearance to inner essence, but the energy dissipation in material inside directly adds thermal material by electromagnetic wave, according to the difference of material dielectric property, and can be timely and effectively at the inner heat that produces of whole material.Heating using microwave has advantages of that conventional heating mode is incomparable: selectively add thermal material, heating rate is fast, the efficiency of heating surface is high; Make material obtain or lose origin of heat in moment, be easy to automatic control.Utilize these advantages of heating using microwave, particularly the high efficiency energy transformation characteristics to high dielectric loss material, is effectively converted into heat energy output by microwave energy, and output meets the high temperature of incubator requirement, clean hot blast, to insulator heating, reach the object addressing the above problem.
