Abstract

The invention relates to a crude oil heating system of a directly-heated type air source heat pump. The crude oil heating system comprises a storage tank (19), an air source heat absorption device and a coil pipe heat exchanger (20), the coil pipe heat exchanger (20) is arranged in the storage tank (19), the air source heat absorption device is connected with the coil pipe heat exchanger (20), and the air source heat absorption device comprises a compressor (1), an oil separator (2), a gas-liquid separator (3), a liquid storage device (4), a four-way reversing valve (5), an evaporation surface air cooler (18) and a gas-liquid mixer (24). The crude oil heating system of the directly-heated type air source heat pump is small in electric energy consumption, high in heat transfer efficiency and wide in application range.

Description

technical field [0001] The invention relates to a crude oil heating system, which is used for heating and constant temperature of dispersed crude oil extracted on site in a crude oil tank. It belongs to the technical field of petroleum industry. Background technique [0002] The existing crude oil heating method generally adopts electric heating, air source heat pump heating crude oil system and heat pump type crude oil heater. Among them, electric heating to heat crude oil consumes a large amount of electricity and has a high cost of use; the air source heat pump heating crude oil system uses secondary water for heating, which has low heat transfer efficiency, and the high-level expansion water tank is easy to freeze in winter, affecting the normal operation of the system; heat pump crude oil heating It is a heating method in the centralized processing and refining process of crude oil, which cannot be applied to the heating and constant temperature of the dispersed crude ...
