Efficient energy-saving gas-phase drying equipment and operation method thereof

Abstract

The invention provides efficient energy-saving gas-phase drying equipment. The efficient energy-saving gas-phase drying equipment comprises a crude oil tank, a buffer tank, an oil-water separator, a condenser, a heat exchanger, an evaporator and a vacuum drying tank. According to the efficient energy-saving gas-phase drying equipment, firstly, hot kerosene steam is utilized to undergo heat exchange with kerosene crude oil, so that the temperature of the hot kerosene entering the condenser is reduced, and the temperature of the kerosene crude oil entering the evaporator is increased; then the condensed kerosene and water are separated through the oil-water separator, and the purity of the recovered kerosene is improved through the oil-water separator; and then the buffer tank is used as a heat exchange carrier, so that the temperature of the kerosene crude oil entering the evaporator is increased, and meanwhile, the temperature of the recovered kerosene entering the crude oil tank is reduced. The efficient energy-saving gas-phase drying equipment has the advantages that the structure is simple, installation is convenient, the safety of the equipment is effectively improved, the energy consumption of the evaporator and the condenser is reduced, meanwhile, the cooling time of the recovered kerosene is reduced, and the recovery working efficiency of the hot kerosene steam subjectedto gas-phase drying is higher.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment drying, and in particular relates to a high-efficiency energy-saving gas-phase drying equipment and an operating method thereof. Background technique [0002] Most of the transformers in large substations are giant transformers. Giant transformers are bound to be damp during disassembly and assembly, so they need to be dried in vapor phase. Kerosene gas phase drying equipment is a relatively advanced special equipment used in the transformer industry to dry coils or transformer bodies. composition. The mobile gas phase drying equipment is to disassemble each module of the drying equipment and transport it to the transformer site, and then assemble it and then dry the transformer. The gas-phase drying equipment used for giant transformers requires a large amount of kerosene, which consumes a lot and costs very high. Therefore, kerosene recovery is one of the problems that must be fac...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the defects in the prior art that it is difficult to recover kerosene from the gas-phase drying equipment, the recovered kerosene has a high temperature and a long cooling time, so that it cannot be quickly transported to the next transformer station for drying, the present invention provides a high-efficiency and energy-saving gas-phase drying equipment
