Description
Technical field
The present invention relates to a kind of new crude oil heating system, is that a kind of heat that utilizes absorption type heat pump system (steam type, hot-water type, direct combustion type) to reclaim oilfield sewage or GEOTHERMAL WATER or solar energy is given the system of heating crude oil.
Background technology
Along with oil field development enters the middle and later periods, oil well is fuel-displaced moisture more and more higher, the dehydration of crude oil and the outer defeated heating that all needs.At present, the heating of crude oil mainly adopts modes such as heating agent stove, water jacket furnace, fire tube boiler to heat, and there are the following problems:
1. adopt the mode of heating efficiencies of heating surface such as heating agent stove, water jacket furnace, fire tube boiler low, the operating cost height;
2. be fuel directly to the dehydration of crude oil, outer defeated heating majority, cause the waste of the energy with crude oil and natural gas;
3. multi-purpose station heating crude oil load is bigger with seasonal variations, adopts the heating furnace heating, the Load Regulation underaction;
4. environmental pollution is comparatively serious.
Simultaneously, the oil field has a large amount of residual heat resources again and is not utilized, and is very unfortunate.At above problem, can design a kind of be that the mode of heating of energy-conservation environmental protection has again become the problem that presses for solution.
Summary of the invention
The purpose of this patent provide a kind of energy-efficient, operating cost is low, the heating crude oil mode of Environmental Safety.
The heat-pump-type crude oil heating system, its characteristics are: remaining hot water pipeline 4 directly or by at least one water/water heat-exchanger rig 1 is connected with the input of absorption type heat pump assembly 2, and crude oil pipeline 7 directly or by at least one crude oil/water heat-exchanger rig 3 is connected with the output of absorption type heat pump assembly 2.
Technical scheme of the present invention is:
1, the heat of sewage or GEOTHERMAL WATER or solar energy installs heat transferred clear water or other medium by heat exchanger or other;
2, clear water or other medium (heat conduction wet goods) are delivered to the heat that obtains in the source pump from sewage or GEOTHERMAL WATER or solar energy, produce the hot water of a higher temperature in the source pump;
The hot water of the high temperature that source pump produces installs heat transferred crude oil (moisture 0.1-99.9%) by heat exchanger or other; Reach purpose to heating crude oil.
Or other scheme:
1, the heat exchanger of sewage or GEOTHERMAL WATER or solar energy side or other device can not wanted, and the getable hot water of sewage or GEOTHERMAL WATER or the sun directly advances the evaporimeter of source pump;
2, the heat exchanger of high-temperature-hot-water side or other device can not wanted yet, and the condenser that crude oil (moisture 0.1-99.9%) directly advances heat pump heats;
Characteristics of the present invention:
1. efficiency of heating surface height
Existing thermal efficiency of heating furnace has only 70～80%, the thermal efficiency 140～180% of heat pump;
2. the remarkable recovery waste heat heat of energy-saving effect is compared with the boiler of efficient 70%, can save the energy about 60%;
3. operating cost is low
Reduce the consumption of the disposable energy (crude oil and natural gas); Realize remote monitoring, regulate automatically, reduce labor intensity that reduce personnel cost, annual operating cost is 40% of a former operating cost;
4. safe and reliable to operation, cycle equipment life is long
Heat pump inner vacuum state, no running gear, more safe and reliable; And Automatic Control, simple to operate; Heat pump does not have the operation parts, and is not fragile, and service life of equipment is about 15 years, far above the life-span in 8 years of plain cylindrical furnace.
5. environment protecting is remarkable
Crude oil and natural gas burning amount reduce significantly, and efficiency of combustion improves, and exhaust gas discharging also reduces significantly;
6. operation is regulated flexibly
Heat pump adds the 20～100% stepless adjustable of heat at it; According to seasonal variations, rationally regulate heating load, energy-saving effect is more remarkable.
