Heat conduction oil heat-exchange system

Abstract

The invention discloses a heat conduction oil heat-exchange system. The heat conduction oil heat-exchange system comprises a heating module and a cooling module, wherein the heating module comprises aheating assembly, and a liquid outlet of the heating assembly is in communication with a heated part through a pipeline; the heated part is connected with a first circulating pump which is in communication with a return port of the heating assembly, and the liquid outlet of the heating assembly is in communication with an inlet pipeline of the cooling module; the cooling module is sequentially and serially connected with a second circulating pump and a cooler, the cooler is connected with a cooled part, and the cooled part is in communication with the outlet pipeline of the cooling module; and the outlet pipeline of the cooling module is connected with the return port of the heating assembly, and the heating module and the cooling module are arranged in parallel. The heat conduction oil heat-exchange system makes the heat-exchange system energy saving, high heat efficiency, uniform heat transfer and accurate temperature control.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat transfer oil heat exchange system. Background technique [0002] With the development of my country's chemical industry, the requirements for the heat carrier in the heat exchange system are becoming more and more stringent, namely: safe operation, constant temperature heating, and no direct heating by the flame. And with the gradual expansion of modern production equipment, the required heat load is also increasing. Electric heating, steam heating, etc. are commonly used in the existing heat carrier heating modules to transfer heat energy to the workpiece. [0003] In the electric heating module, the power consumption is high, the cost is high, and the heat loss is large, and the electric heating inevitably has overshoot and temperature control lag during work, especially in large-scale equipment when the current is too large, it is easy to generate local high temp...

Problems solved by technology

In this way, the heat exchange materials of heating equipment and heat-using equipment, the pressure level of equipment, and the manufacturing requirements will all increase accordingly, and the system structure is complex, the investment cost is high, the management is inconvenient, and the risk is extremely high. Moreover, the recovery technology of condensed water and device management There are great difficulties in all aspects, and the thermal efficiency can only reach about 70%. When the temperature reaches above 200°C, heating with steam has a fatal weakness.
