Description
Technical Field
The utility model relates to a pipeline type electromagnetic induction heating device.
Background
At present, the taurine preparation process commonly adopted by taurine production enterprises is an ethylene oxide method. The main principle of the reaction is as follows:
addition reaction NaHSO4+CH2CH2O→HOCH2CH2SO3Na
Ammonolysis reaction HOCH2CH2SO3Na+NH3→NH2CH2CH2SO3Na+H2O
Neutralization reaction NH2CH2CH2SO3Na+H2SO4→NH2CH2CH2SO3H+Na2SO4
Wherein the ammonolysis reaction can be effectively carried out under the conditions of 17 MPa-20 MPa of pressure and 245-270 ℃. This necessitates heating the mixture which participates in the aminolysis reaction.
Because the mixed materials participating in the ammonolysis reaction have the characteristics of high pressure, low flow and high viscosity, at present, a sleeve type heat conduction oil heater is generally adopted by taurine production enterprises to heat the materials of the ammonolysis reaction. The sleeve type heat conducting oil heater can meet the requirements of a production process, but has the defects of low heating efficiency, large occupied area, poor temperature control effect, lagging temperature regulation and the like. In addition to the above disadvantages, the manufacturing enterprises using the double pipe type conduction oil heater must also construct a conduction oil heating boiler, which greatly increases the construction cost and the production cost of the production line.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a pipeline type electromagnetic induction heating device which is high in heating efficiency, small in occupied area, good in temperature control effect and timely in temperature adjustment.
In order to solve the technical problem, the utility model provides a pipeline type electromagnetic induction heating device which comprises a heating pipe made of carbon steel materials, wherein a heat insulation layer is arranged on the outer side of the circumference of the heating pipe, a heating area is arranged in the middle of the heat insulation layer in the length direction, an electromagnetic induction coil is wound on the outer side of the heat insulation layer corresponding to the heating area, a cylindrical stainless steel shielding cover is arranged on the outer side of the electromagnetic induction coil, and two ends of the shielding cover in the length direction are in a closing structure and are attached to the heat insulation layer.
For the sake of simplicity, the pipeline type electromagnetic induction heating device of the present invention is simply referred to as the present device.
The device has the advantages that: the device solves the problems of low heating efficiency, large occupied area, poor temperature control effect, lagging temperature regulation and the like of the heating scheme of the traditional sleeve type heat conducting oil heater, and has the advantages of rapid temperature rise, high heat utilization rate, intelligent temperature regulation and the like under the matching action of corresponding instrument control facilities. Meanwhile, the device does not need a heat-conducting oil heating boiler matched with a production enterprise, so that the construction cost and the use cost are reduced, open fire in a production device area is avoided, and the production safety risk is reduced.
In order to achieve better using effect of the device, the preferred scheme is as follows:
preferably, the heat insulation layer adopts compound magnesium aluminum silicate or closed-cell foam glass.
The composite magnesium aluminum silicate and the closed-cell foam glass have the effects of heat insulation, flame retardance and insulation, so that potential safety hazards are avoided, and the heating efficiency can be increased.
Preferably, a hollow interlayer is arranged in the shielding cover material, and inert gas is filled in the hollow interlayer.
Due to the existence of high temperature and a magnetic field, the stainless steel shielding case has high oxidation speed, and the hollow interlayer is arranged in the shielding case material and filled with inert gas, so that the oxidation speed can be reduced, and the maintenance period of the device can be prolonged.
Preferably, a plurality of fins extending inwards along the radial direction of the heating pipe are arranged in the heating pipe.
The fins arranged in the heating pipe can increase the contact area between the heating pipe and internal materials, so that the heat transfer efficiency is increased.
