Background technology
Along with Oilfield developing enters the middle and later periods, oil well fuel-displaced moisture more and more higher, the dehydration of crude oil and the outer defeated heating that all needs.Present raw oil heater is generally the oil field water batch heater, and at present commonly used have following several form:
Form by the fuel-firing gas-firing water heater, fuel-firing gas-firing burns in boiler, recirculated water enters into water bath after absorbing heat, crude oil is carried be heated to the heat that needs in water bath after, the energy utilization mode of this form is actual to be to adopt the burning high-grade energy to obtain low grade heat energy, and active power is low;
Adopt the form of fuel-firing gas-firing absorption heat pump, this method has been improved efficiency of energy utilization to a certain extent, and it can be reached more than 1, but this kind apparatus cost costliness, and efficiency of energy utilization can't reach the degree of compression heat pump simultaneously;
Adopt the form of electronic compression heat pump, the outlet temperature of common compression heat pump is lower, generally is difficult to satisfy the needs of heating crude oil, simultaneously in the electricity price of field area than fuel-firing gas-firing height, economy is bad.
The temperature of oil-polluted water is up to 40-50 ℃, this part low-temperature energy sources is not used, as the waste of resource, have only employing heat pump (heat pump that comprises absorption heat pump or compression) just can make full use of this part low-grade energy, reach the reasonable efficient application of the energy.
Summary of the invention
Based on above-mentioned technical background,, must improve the outlet temperature and the economy of electronic compression heat pump if adopt the form of electronic compression heat pump to be applied to heating crude oil.
The technical scheme that its technical problem that solves the utility model adopts is: improve for making the heat pump outlet temperature, the working medium of heat pump no longer adopts common middle temperature cold-producing medium such as R22 and R134a etc., and adopts special high temperature refrigerant, as R142b, and R406a.Adopt the heat pump of this working medium, leaving water temperature can reach 85 ℃, the highlyest can reach 95 ℃, also have simultaneously than higher heating efficiency, for example under condensation temperature was 85 ℃ situation, its heating efficiency can reach 3.5, is a kind of very desirable high temperature refrigerant.
Aspect power resources, in order further to improve efficiency of energy utilization and heat pump outlet temperature, can adopt the fuel-firing gas-firing engine as power resources, utilize interior circulation used heat of cylinder sleeve of engine and waste-gas heat heat cycles water more simultaneously, the dynamic efficiency of fuel-firing gas-firing engine generally can be reached about 30%, in the middle of the 70% remaining used heat, have 55% can be recycled water and absorb again, have only 15% can not be utilized, finally be discharged in the environment.
Adopt the heat pump assembly of fuel-firing gas-firing engine, its efficiency of energy utilization is the highest can be reached more than 1.8, not only surpasses oil-burning gas-fired boiler, also leads over absorption heat pump, is a kind of energy saver very efficiently.
Aspect cost, fuel-firing gas-firing heat-pump-type raw oil heater has slightly high initial cost than conventional art, aspect operating cost, because its comprehensive utilization of energy efficient doubles than conventional oil-burning gas-fired boiler, so its operating cost can reduce about one times, simultaneously again because have than the better rate of exchange of electricity, so aspect investment repayment, have sizable advantage at the oilfield internal fuel-firing gas-firing.In addition, because the raising of efficiency of energy utilization and utilize clean energy resource, so help the environmental protection cause in oil field greatly.
This utility model is compared with existing technologies, has following characteristics:
1. efficiency of energy utilization height: as mentioned above, efficiency of energy utilization is than one times of oil-burning gas-fired boiler improved efficiency;
2. energy-saving effect is remarkable: the recovery waste heat heat, with the oil-burning gas-fired boiler of efficient 90% mutually specific energy save about 50% energy;
3. operating cost is low: this device initial cost aspect may be than conventional boiler height, but when operation, reduce the consumption of the disposable energy (crude oil and natural gas), operating cost significantly reduces, thus can be in a short period of time saving by operating cost obtain regaining;
4. environment protecting is remarkable: crude oil and natural gas burning reduce significantly, and efficiency of combustion improves, and exhaust gas discharging also reduces significantly.
Description of drawings
Accompanying drawing is a systematic schematic diagram of the present utility model.
The specific embodiment
In conjunction with the accompanying drawings this use novel product is described further.
As shown in the figure: 7 is evaporimeter, and the outlet of evaporimeter 7 links to each other with the inlet of compressor 5, and the outlet of compressor 5 links to each other with the inlet of condenser 4, on the connecting pipe of condenser 4 and evaporimeter 7 expansion valve 6 is arranged, and more than forms the refrigerant loop of heat pump; Evaporimeter 7 connects thermal source supply channel and thermal source water return pipeline; The outlet pipeline of circulation heated water bath groove 1 inserts fuel-firing gas-firing engine 3 backs by condenser 4 and further inserts flue gas heat recovery device 2, and the outlet pipeline of flue gas heat recovery device 2 is linked on the circulation heated water bath groove again; Oil water mixture in the oil well 11 is extracted out by pump 9 by bottom valve 10, be separated into crude oil and water by oil water separator 8, the part of water becomes the water inlet of evaporimeter 7, the water outlet of evaporimeter 7 enters in the oil well 11 by pipeline, untreated oil line enters in the coil pipe of circulation heated water bath groove, the output of heating back;
