During use, the control range of design temperature on the temperature control temperature instrumentation as required, when the fluid temperature (F.T.) of the heating reactor coil of flowing through reaches the control temperature, temperature sensor sends information to the temperature control temperature instrumentation, the temperature control temperature instrumentation cuts off the power supply of heater, when the fluid temperature (F.T.) of the heating reactor coil of flowing through was lower than the control temperature, temperature sensor sent information to the temperature control temperature instrumentation, the power supply of temperature control temperature instrumentation conducting heater.
In order to realize goal of the invention better, the present invention has also taked following technical measures:
1, heater mainly by matrix, be installed in the ceramic heating element on the matrix and connect ceramic heating element and the wire assembly of power supply is formed.
2, thermal conductor constitutes by plate body with perpendicular to the heat transfer sheet of plate body setting, and the heating reactor coil is wrapped on the heat transfer sheet that is provided with perpendicular to plate body; The quantity of heat transfer sheet both can be even number, can be odd number also, but was preferably odd number and is at least three.When heat transfer sheet was odd number, the heating reactor coil was wrapped on the heat transfer sheet at interval, and the heat transfer sheet that is wound with the heating reactor coil is not wound with between the heating plate that heats reactor coil at two.
3, be provided with muff, muff is set on thermal conductor and the heater, and shape and size after its shape and size make up with thermal conductor and heater are complementary.
4, the inwall at muff top is coated with thermal insulation layer.
The present invention has following beneficial effect:
1, owing to disposed temperature control temperature instrumentation and temperature sensor, thereby is convenient to regulating and controlling temperature, makes the fluid temperature (F.T.) of the heating reactor coil of flowing through constant and meet the reaction requirement, avoid overheated.
2, since the ceramic heating element of heater when temperature is elevated to certain value, no longer raise, thereby constant in certain limit from thermal source guaranteed the to flow through fluid temperature (F.T.) of heating reactor coil.
3, the structure of thermal conductor makes the heating reactor coil be heated evenly.
4, the setting of muff and thermal insulation layer not only can improve the heat efficiency, strengthens the constant temperature effect, energy savings, and also the fluid temperature (F.T.) in the heating reactor coil is higher than 50 ℃ of useful lifes that also do not influence the temperature control temperature instrumentation.
5, all members are loaded in the housing, and are rational in infrastructure, easy to operate.
