Organic heat carrier regeneration device and method

Abstract

The invention discloses an organic heat carrier regeneration device and method. The device comprises an automatic constant-temperature controllable electric heater, a first flash tank, a second flash tank, an oil-mist separator, a high-boiling residue tank, a low-boiling residue tank, an intermediate component tank and a regeneration purifier. The automatic constant-temperature controllable electric heater and the first flash tank are in backflow connection through a pipeline to form the first heating cycle, and the automatic constant-temperature controllable electric heater and the second flash tank are in backflow connection through a pipeline to form the second heating cycle. The top of the first flash tank and the top of the second flash tank are connected with the oil-mist separator through pipelines respectively. The first flash tank is connected with the high-boiling residue tank and the second flash tank through pipelines respectively. The second flash tank is connected with the high-boiling residue tank, the low-boiling residue tank and the intermediate component tank through pipelines respectively. The intermediate component tank is in backflow connection with the regeneration purifier through a pipeline to form the purification cycle. The quality of oil products is improved, and the service life of an organic heat carrier is prolonged.

Description

Technical field [0001] The invention relates to the application field of organic heat carrier, in particular to an organic heat carrier regeneration device and an organic heat carrier regeneration method. Background technique [0002] The recovery and regeneration of organic heat carrier is the future development trend. For boilers and heat transfer systems using synthetic organic heat carriers, when the oil quality changes and deteriorates, the index values ​​such as carbon residue, acid value, kinematic viscosity, etc. approach or reach GB24747-2009 "Safety Technical Conditions for Organic Heat Carriers" According to incomplete statistics, more than 98% of enterprises directly burn the degraded oil as fuel and replace them with new organic heat carriers, according to incomplete statistics. It causes environmental pollution and is also a great waste. Summary of the invention [0003] In view of the above technical problems, the present invention provides an organic heat carrier...
