Abstract

The invention provides a gas phase drying kerosene recycling system and a recycling method thereof. The system is composed of a kerosene storing tank, a condenser, a heat exchanger and an oil-water separator. Due to the fact that a kerosene recycling device is added in a gas phase vacuum drying device to recycle hot kerosene after being dried, hot kerosene steam is utilized for performing heat exchanging with kerosene crude oil, the temperature of the hot kerosene entering the condenser is lowered, and the temperature of the kerosene crude oil entering an evaporator is increased; and keroseneafter being condenser and water are separated through the oil-water separator, and the purity of the recycled kerosene is improved through the oil-water separator. The gas phase drying kerosene recycling system can be used for performing high-purity recycling on the hot kerosene, meanwhile energy circulation is achieved, and the energy consumption of gas phase drying is lowered.

Description

technical field [0001] The invention belongs to the technical field of electrical vacuum drying tanks, and particularly relates to a kerosene recovery device and a recovery method for gas-phase vacuum drying tanks. Background technique [0002] During the process of disassembly and assembly, the transformer must be damp, so after assembly, it must be dried in the gas phase. Or after the giant transformer is repaired in the power station, it also needs to be dried in the gas phase. Gas phase drying treatment is currently the most convenient and time-saving transformer drying method. The existing gas phase drying equipment is mainly composed of condensation system, vacuum system, heating system, control system and gas phase system with evaporator as the core. Gas-phase drying is done by heating and evaporating kerosene and then connecting it to the oil tank of the transformer body, or placing the transformer in a vacuum drying tank for drying. [0003] The current vacuum dry...
