There are a reaction pot for performing various chemical reactions, a food heating device, and a medical product sterilization device. 2. Description of the Related Art As a conventional steam heating device, for example, a device disclosed in Japanese Patent Application Laid-Open No. 4-290556 has been used. In this method, a liquid reservoir is provided at a lower portion of a jacket portion of a reaction vessel, a heat medium is sealed in the liquid reservoir, and the heat medium is heated by an appropriate heating means to generate a medium vapor for heating, and a jacket portion is formed. Is used to heat the reaction vessel with steam. [0003] The above-mentioned conventional heating apparatus has a problem that the heating temperature cannot be kept constant. In particular, when the temperature or the amount of the object to be heated changes greatly, there is a problem that the heating temperature also changes greatly. This is because the temperature of the object to be heated is reduced or the amount is increased because the jacket as the heating chamber is kept at a predetermined pressure state and the heating medium is heated by the heating steam generated by heating. In addition, the condensation of the heating medium vapor increases, so that the vapor pressure in the heating chamber rapidly decreases, and the heating temperature also decreases. [0004] Accordingly, it is an object of the present invention to provide a steam heating apparatus capable of maintaining a constant steam heating temperature irrespective of fluctuations in the temperature and the amount of the object to be heated. [0005] The constitution of the steam heating apparatus of the present invention is as follows. A heat exchanger having a heating chamber, a heating medium reservoir connected to the heating chamber, and heating means for heating the heating medium in the heating medium reservoir to generate a heating medium vapor; The means is formed by a high-temperature steam device, a pressure detection unit for detecting a medium vapor pressure of the heating chamber is attached, and a heating amount control unit for controlling a heating heat amount in the high-temperature steam device according to a detection signal from the pressure detection unit is provided. It is provided. The heating medium is heated and vaporized by the high-temperature steam equipment, so that the heating chamber is filled with the heating medium vapor and heats the heat exchanger. In this case, when the medium vapor pressure in the heating chamber is detected by the pressure detecting means and the amount of the heating target is increased by controlling the amount of heating heat according to the detected pressure value, and the medium vapor pressure suddenly decreases. However, the pressure drop of the medium for heating, that is, the temperature of the heated steam, can be kept constant by detecting the pressure drop by the pressure detecting means and rapidly increasing the amount of heating heat in the high-temperature steam equipment. An embodiment shown in the drawings will be described in detail. In this embodiment, an example in which the reactor 1 is used as a heat exchanger will be described. Jacket section 2 as a heating chamber formed on the outer periphery of reaction vessel 1
A pressure sensor 7 as pressure detecting means attached to the jacket portion 2; a heat medium reservoir 3 provided continuously below the jacket portion 2; and a heating means for heating the heat medium 4 in the heat medium reservoir 3. And a heating amount control unit 6 for controlling the amount of heating heat of the high-temperature steam device 5 constitute a steam heating device. A pressure sensor 7 for detecting a medium vapor pressure for heating the inside of the jacket portion 2 is attached. Heat medium reservoir 3 connected to the lower part of jacket 2
Communicates with the jacket portion 2 through the passage 8 and stores therein a heat medium 4 such as water or dowsome. The air inside the jacket portion 2 is almost completely removed in advance. A high-temperature steam coil 9 is provided inside the heat medium reservoir 3.
Is arranged. An electric valve 10 is provided on the inlet side of the high-temperature steam coil 9.
High-pressure steam pipe 12 through
And a steam trap 15 for heating the heat medium 4 and discharging condensed condensate is connected to the outlet side.
The control valve 11 and the motor-operated valve 10 are connected to a pressure sensor 7 via a controller 13. Control valve 11 and controller 1
3 together form a heating amount control unit 6. The opening degree of the control valve 11 is adjusted by the controller 13 so that the high-temperature steam coil 9 is controlled.
The pressure and flow rate of high-temperature steam supplied to the heating medium 4
It controls the amount of evaporation. Next, the operation will be described. When heating the reactor 1, high-temperature steam is supplied to the high-temperature steam coil 9 to heat and evaporate the heat medium 4. The evaporated vapor of the heat medium 4 reaches the jacket portion 2 from the passage 8 and heats the reaction vessel 1 and heats an object to be heated in the reaction vessel 1 (not shown). The condensed liquid of the medium vapor condensed by heating the reactor 1 is dropped from the lower portion of the jacket portion 2 to the heat medium storage portion 3 and is heated again. There is a correspondence between the heating medium vapor pressure in the jacket portion 2 and the temperature, and the heating temperature to the reactor 1 can be controlled by adjusting the medium vapor pressure. When the temperature of the object to be heated in the reaction vessel 1 decreases or increases, the medium vapor in the jacket portion 2 condenses and the medium vapor pressure temporarily drops. By detecting and increasing the amount of heating of the high-temperature steam equipment 5 via the controller 13, the amount of evaporation of the heat medium 4 can be increased to recover the medium vapor pressure, that is, the medium vapor temperature. , The heating temperature can be kept almost constant. In this embodiment, an example is shown in which the reactor 1 is used as a heat exchanger. However, the present invention can also be used as a heat exchanger for other heating devices, sterilizers and the like. Further, in the present embodiment, an example is shown in which the heating medium vapor and the condensate communicate with each other via the passage 8, but a plurality of passages are provided, and the heating medium vapor is supplied from one of the passages. Alternatively, the condensed liquid can be circulated so as to drip from the other passage. According to the present invention, even if the temperature and amount of the object to be heated fluctuate and the vapor pressure of the heating medium changes, the pressure detecting means detects the pressure and detects the high-temperature steam equipment. By controlling the amount of heating heat via the above, it is possible to quickly correct the pressure change, that is, the change in the medium steam temperature, and obtain a steam heating device capable of maintaining a constant heating temperature to the heat exchanger. it can.
