Abstract
The utility model discloses a geothermal energy heating device of a petroleum transmission pipeline, which mainly comprises a geothermal energy heat pump machine 9, a hot water tank 6, a circulating water pump 17, a heat cycling water pipe 2, a terrestrial heat circulating water tank 13, a terrestrial heat circulating water pipe 11, a terrestrial heat exchanger 10 and a terrestrial heat circulating water pump 12. Geothermal energy is one of various heating modes with higher heating efficiency, and the geothermal energy heat pump machine can be used for heating water to above 60 DEG C, and can be applied to heating of the petroleum transmission pipeline, and thus the geothermal energy heating device can solve the problems of high heating energy consumption, large pollution, high cost and short service life of the traditional coal or oil burning boiler or electric heater, and is convenient to install.
Description
Technical field
The utility model relates to a kind of petroleum delivery pipeline geothermal energy heater.
Background technology
Oil will be transported to oil storage tank by oil pipeline after extracting out in the oil well.The oil of just extracting out from oil well is a kind of water oil mixture, and temperature is about 20 ℃, and viscosity is large, is not suitable for direct conveying, when it is carried to oil storage tank, be heated to 32 ℃ and maintenance, reduces its viscosity.Method is to be close to oil pipeline the circulating-heating water pipe is installed, and inputs continuously 50 to 60 ℃ hot water heating oil pipeline to the circulating-heating water pipe.Produce at present 50 to 60 ℃ of hot water, the method for use has fire coal or oil burning boiler heating, electric heater heating.Wherein there is the shortcoming that efficient is low, pollution is large, cost is high in the heating of fire coal or oil burning boiler, and there is low, the short-life shortcoming of efficient in the electric heater heating.Adopt the geothermal energy heat pump machine that low-grade geothermal energy is promoted to high-grade heat energy, can be used for petroleum delivery pipeline is heated.
Goal of the invention
The utility model discloses a kind of technical scheme of petroleum delivery pipeline geothermal energy heater.
The utility model content
The utility model is by geothermal energy heat pump machine, boiler, water circulating pump, circulating-heating water pipe, underground heat cyclic water tank, and underground heat circulating water pipe, geothermal heat exchanger and underground heat water circulating pump consist of.The circulating-heating water pipe is close to oil pipeline and is installed, hot water tank outlet and water circulating pump water inlet join, water circulating pump delivery port and circulating-heating water pipe water inlet join, boiler water inlet and circulating-heating water pipe delivery port join, or boiler water inlet and water circulating pump delivery port join, water circulating pump water inlet and circulating-heating water pipe delivery port join, hot water tank outlet and circulating-heating water pipe water inlet join, the condenser of geothermal energy heat pump machine is fixed in the boiler, the evaporimeter of geothermal energy heat pump machine is fixed in the underground heat cyclic water tank, the compressor of geothermal energy heat pump machine is connected between condenser and the evaporimeter, heating agent in the compression condensation device, water in the boiler is heated to 50 to 60 ℃, continuously delivery is heated oil pipeline to the circulating-heating water pipe by water circulating pump, underground heat circulating water pipe water inlet and delivery port be ground connection thermal cycle water tank and geothermal heat exchanger delivery port and water inlet respectively, geothermal heat exchanger is installed on below the frozen soil layer of oil field, and the underground heat water circulating pump is connected on the underground heat circulating water pipe.
Geothermal energy heat pump machine power calculation will be according to daily flow, and fed distance determines, the daily output calculate promote temperature need energy, fed distance calculate keep temperature need energy.Although the oil water mixture specific heat ratio water of extracting out from oil well is little, we still press specific heat of water and calculate for example, and the plant capacity that calculates like this is larger 20% to 50% than intensification power demand, just in time as the plant capacity surplus.The below is with 4 tons of the dailys output, and the oil well that fed distance is 600 meters is example, calculates geothermal energy heat pump machine power.The first, calculating promotes temperature and wants work, 4 tons of oil water mixtures is risen to 32 ℃ of works of wanting from 20 ℃ be:
4 * 1000 (Kg) * 12 (℃) * 1 (kilocalorie/Kg ℃)=48000 (kilocalorie)
Second, calculate and carry 600 meters insulations to want work, learn according to measured data, at present under the insulation level, every meter dissipated power of the oil pipeline that diameter is 60 millimeters is 50W, every meter dissipated power of the oil pipeline that diameter is 76 millimeters is 65W, and take 60 millimeters oil pipelines of diameter as example, 600 meters oil pipeline dissipated powers are:
600×50(W)＝30000(W)
600 meters oil pipeline loss every day heats are:
30 (KW) * 860 (kilocalorie/KW hour) * 24 (hour)=619200 (kilocalories)
Promoting temperature every day and being incubated wants work to be:
48000+619200=667200 (kilocalorie)
Because the Energy Efficiency Ratio of geothermal energy heat pump machine can reach 1: 4, thus every day directly by the hot merit of electric energy conversion be:
667200 (kilocalorie) ÷ 4=166800 (kilocalorie)
Can get thus geothermal energy heat pump machine power is:
166800 (kilocalorie) ÷ 24 (hour) ÷ 860 (kilocalorie/KW hour) ≈ 8 (KW).
The general size of circulating-heating water pipe diameter and oil pipeline gets final product.
Water circulating pump and underground heat water circulating pump power are 300W to 500W in this example, and all the other increase according to circulating-heating water pipe diameter or reduce.
