Flue gas assisted heavy oil thermal recovery integrated special equipment for oil field steam-injection boiler

The utility model provides an oil field steam-injection boiler flue gas assisted thickened oil thermal recovery integrated special device, and belongs to petroleum equipment and oil recovery processes. The system comprises a heat exchange module, a filtering module and a pressurizing module. The heat exchange module comprises a heat exchanger, high-temperature flue gas is used for preheating boiler water, and waste heat of the flue gas is recycled. The filtering module comprises a freezing dryer, a first-stage filter and a second-stage filter, and equipment corrosion and pollution can be effectively reduced; the pressurization module comprises a compressor and a supercharger, and the requirement for oil field flue gas injection operation is met through secondary pressurization. The device is characterized in that the flue gas generated by the oil field steam-injection boiler is subjected to heat exchange, filtration and pressurization treatment. The whole device is designed in a skid-mounted mode, has the adv
