High and low temperature circulating device for GDSZ-300L/-40
An overview of the high and low temperature circulating device at GDSZ-300L/-40:
The product has been the national patent, patent number: ZL201020214881.4 201010191432.7
A series of high and low temperature liquid circulation device in the whole system is closed, with the system expansion tank expansion container and liquid circulation system is adiabatic, does not participate in the liquid circulation, only mechanical connection, regardless of the temperature of the liquid circulation, the expansion in the container medium is always kept at room temperature.
Because the whole liquid circulation is a closed system, so there is no absorption of water vapor at low temperature, high temperature without the production of oil mist. The company can provide a wide range of working temperature of heat transfer oil, so the same machine with a heat conduction medium can achieve -90.
The characteristics of GDSZ-300L/-40 high and low temperature circulation device are as follows
- no internal circulation tank, small volume in circulation (most of the equipment within the cycle of the volume is only 6-10L), effective power density (W/L), heating and cooling rate is fast, demand for oil is relatively small.
The equipment adopts wavy plate heat exchanger, heat exchange area, high heat exchange speed.
The whole sealed liquid circulation at high temperature without oil mist evaporation, heat conducting oil are not oxidized or browning; does not absorb water vapor in the air temperature, prolong the service life of heat conducting oil with low cost.
The precise control of the temperature of the chemical reaction, is the first choice of safety control exothermic reaction.
The equipment adopts PID intelligent control, automatic adjusting the output power according to the chemical process, precise control of reaction temperature, the reaction process to meet the requirements of temperature changes.
Circulating pump - special custom, can provide maximum flow, minimum pressure and heat, to achieve the highest efficiency of heat exchange system, the minimum resistance, heat pump system is the smallest system, the minimum energy consumption.
The standard type is controlled by PLC, the more human interface (HMI), simple operation, can display the working process of the set temperature, outlet temperature, the kettle body temperature change curve, realize the program of lifting temperature programming.
Safety requirements - standard can be provided according to the reactor manufacturers, set the maximum temperature of the kettle body and the inner difference, if the temperature reaches the value inside and outside the device will automatically stop and alarm limit of safety requirements of manufacturers, ensure that the reactor will not because of the temperature difference is too large and broken.
