Description
Technical field
The utility model relates to the equipment of grade heat energy utilization of a kind of end, especially a kind of heating output crude oil by using oil field produced water heat pump equipment.
Background technology
China has the sewage behind a large amount of oil field separation crude oil to want re-injection, and only Shengli Oil Field just has 300,000,000 tons every year; Because the sewage temperature of re-injection is higher, so the heat energy in the sewage runs off in vain; And crude oil exporting needs heat pump gas-firing or crude oil, has wasted a large amount of fuel on the one hand, has increased cost, produces the CO2 emission contaminated environment simultaneously again.Chinese patent 200510104455.9, disclose a kind of oilfield sewage used heat and driven double absorption refrigerating technique and equipment, because oilfield sewage used heat graphite boiler operatiopn pressure height, water attack easily cause booster when producing, and fouling generation and field produces are arranged with factors such as refrigeration are less, fail large scale application over 3 years.Therefore, effectively reclaim sewage heat energy, reduce the energy consumption and the environmental pollution of crude oil exporting, become the important topic in the oil exploitation process.
Summary of the invention
The purpose of this utility model provides a kind of heating output crude oil by using oil field produced water heat pump equipment, with the loss that solves return water heat energy, energy consumption and this technical problem of environmental pollution that reduces crude oil exporting.The utility model is to realize like this, heating output crude oil by using oil field produced water heat pump equipment links to each other by pipeline pump with heat exchanger, the heat exchanger left end links to each other with pump by pipeline, pump links to each other with the working medium evaporimeter by pipeline again, and working medium evaporimeter right-hand member links to each other with heat exchanger by outer discharge pipe again; The working medium evaporimeter links to each other with separator by pipeline again, separator links to each other with compressor by pipeline, compressor links to each other with the working medium cooler by pipeline again, the working medium cooler links to each other with the working medium condenser by pipeline, the working medium condenser links to each other with the working medium evaporimeter with choke valve respectively by pipeline again, and choke valve links to each other with separator again; Pump links to each other with the working medium condenser by crude oil pipeline, and the working medium condenser links to each other with the working medium cooler by crude oil pipeline again.The utility model utilizes heating output crude oil by using oil field produced water heat pump, and oil field extracted water heat energy is efficiently utilized, and the not direct combustion fuel of heat pump does not produce CO
2Toxic emission is a kind of environment amenable equipment.Simultaneously, utilize oil field produced water heat pump to provide required heat for the crude oil exporting production technology, can save a large amount of natural gases or oil, compare with the crude oil heater of routine, the oil field produced water heat pump Energy Efficiency Ratio is higher, and oil field produced coolant-temperature gage, stability of flow.
