Detailed Description
The present invention is further illustrated by the following examples, which should not be construed as limiting the scope of the invention.
Example (b): compare FIG. 1
The utility model provides a steam heating automatically regulated control system, includes reation kettle 5 and steam condensate storage tank 6, and 5 outsides of reation kettle are provided with the heat transfer and press from both sides the cover, and heat transfer presss from both sides cover upper portion and is connected with steam inlet pipeline 1, and heat transfer presss from both sides cover bottom through gas-liquid mixture outlet pipe 2 and 6 sub-unit connections of steam condensate storage tank, and 6 tops of steam condensate storage tank are passed through steam gas phase outlet pipeline 4 and are connected with steam inlet pipeline 1, and steam condensate storage tank 6 is connected with steam condensate outlet pipeline 3.
Be equipped with the level gauge that is used for measuring its inside condensate liquid level on steam condensate storage tank 6, be equipped with the liquid level control valve on the steam condensate outlet pipeline 3, the level gauge passes through PLC control system and liquid level control valve signal connection, and the data transmission of the steam condensate storage tank 6 inside condensate liquid level that the level gauge will detect gives PLC control system, through the aperture of PLC control system control and regulation liquid level regulating valve to make 6 inside condensate liquid levels in steam condensate storage tank keep stable, thereby realize the stability of steam heating process in the heat transfer jacket in the reation kettle 5 outside.
The steam condensate storage tank 6 is of a vertical structure and made of carbon steel or stainless steel, and a thermometer, a pressure gauge and a liquid level gauge are arranged on the steam condensate storage tank 6.
The reaction kettle 5 is of a vertical structure and is made of carbon steel, stainless steel or glass lining.
The application discloses a steam heating regulation control system can be applied to fields such as fine chemistry industry, medicine, is applicable to the process of steam steady heating. The steam trap can completely replace the existing steam trap, effectively control the heating process of steam, reduce the fluctuation of steam media and improve the heat exchange effect of steam.
The device of this application during operation: the hot steam enters the heat exchange jacket at the outer side of the reaction kettle 5 and is partially condensed to form a gas-liquid mixture. The gas-liquid mixture in the heat exchange jacket enters a steam condensate storage tank 6 for separation, the upper part is hot steam, and the lower part is steam condensate.
In actual industrial production, hot steam introduced into the heat exchange jacket heats the operation process in the reaction kettle 5. However, if the operation process in the reaction kettle 5 is unstable and the temperature is suddenly and continuously reduced, the amount of steam condensation in the heat exchange jacket is increased, the level of the condensed water in the steam condensate storage tank 6 is slowly increased, the gas space at the upper part of the steam condensate storage tank 6 is slowly reduced by the dynamic process of the liquid level increase, the continuously increased liquid level gradually compresses the hot steam in the gas space upwards, certain reverse thrust power is provided for the newly added hot steam in the steam inlet pipeline 1, and the amount of the newly added hot steam outside is reduced. Once the amount of steam entering the heat exchange jacket is reduced, the temperature in the reaction kettle 5 is further reduced, and the heating stability of the system is greatly influenced.
Consequently, this application device is through regulating and control the comdenstion water liquid level in the steam condensate storage tank 6, makes 6 inside condensate liquid levels of steam condensate storage tank remain stable, can further realize the stability of steam heating process in the heat transfer jacket in the 5 outsides of reation kettle.
The statements in this specification merely set forth a list of implementations of the inventive concept and the scope of the present invention should not be construed as limited to the particular forms set forth in the examples.
