AI Technical Summary

Problems solved by technology

[0003] Due to the unreasonable use of the existing heat transfer oil, the local temperature of the heat transfer oil in the system is too high and cracked, resulting in more light components, which are not suitable for discharge, and bring a great burden to the operation of the system
If the light components in the system cannot be discharged in time, a vicious circle will be formed and the cracking and decomposition speed of the heat transfer oil will be accelerated

Abstract

The invention is aimed at providing a separating and purifying system of light components in heat transfer oil. The separating and purifying system is obtained by on-line transformation of a light-component discharging system. The separating and purifying system is characterized in that: the separating and purifying system comprises a separating and circulating system, a cooling and collecting system and a vacuum-pumping system. The separating and circulating system comprises an oil-gas separator and a heating medium pump. The cooling and collecting system comprises a cooler A, a light-component collecting tank and a circulating pump. The vacuum-pumping system comprises a cooler B, a vacuum pump and a waste-water collecting tank.

Description

Technical field: [0001] The invention relates to a heat-conducting oil heating system in a petrochemical plant; it is suitable for separating, purifying, and recycling the heat-conducting oil that deteriorates sharply due to high temperature when the organic heat-conducting oil in the chemical plant operates at high temperature. Specifically, it relates to a heat transfer oil light component separation and purification system. Background technique: [0002] Heat transfer oil is a high-quality heat transfer medium with high heat transfer efficiency. It is forced to circulate in the liquid phase by the circulating oil pump in the furnace. However, if it is stored and used improperly, it will also deteriorate and affect normal use. The main reasons for the deterioration of heat transfer oil are: (1) local overheating and cracking. If the heat transfer oil exceeds its specified maximum service temperature, it will overheat locally, resulting in thermal decomposition and polyc...
