Description
Technical field
The present invention relates to a kind of oil pipeline, the plumbing installation of a kind of heated transportation oil.
Background technology
The oil pipeline of distance is made up of oil transportation station and pipeline two parts, and length is the most longer up to several hundred kilometers, is provided with initial station, several intermediate stations and terminal along the line.Oil pipeline multichannel is through scarcely populated desert, basin or highlands, in order to reduce resistance, takes straight-run, and generally over ground installation the most as far as possible.The energy that the flowing of oil product in-line is consumed is provided by oil transportation station.The pipeline of transporting oil, owing to dielectric viscosity is relatively big, poor fluidity, needs heating the most along the line, need to consider the power that Thermodynamics and the pumping plant from hydromechanical angle estimator with pipeline desirable pressure balance are provided.Oil viscosity Gao Shihui makes the pressure drop of pipeline be greatly increased, and not only can expend a large amount of power and have potential safety hazard, and the method for heated transportation therefore must be used to reduce viscosity, the effect of less frictional resistance.Heated transportation is the mode that current transporting oil commonly uses.By oil stream whether by furnace tubing, it is divided into and directly heats and indirectly heat two ways.The former directly heats oil stream in heating furnace, and the latter is to make heating agent pass through heating furnace to improve after temperature, enters in heat exchanger and adds deep fat stream.Oil stream is heated by pipeline heated transportation process at heating station, generally, is always to try to together with a heating station build in pumping plant.The most frequently used firing equipment is heating furnace.Heated transportation pipeline must use heat-insulation layer, with saving heat energy.But at the oil pipeline away from heating station because of the loss of heat, the temperature decline of oil product, viscosity rises, and mobility declines, and can increase the load of oil transfer pump, reduces transfer efficiency.
Summary of the invention
The technical problem to be solved is for above-mentioned the deficiencies in the prior art, it is provided that the plumbing installation of the heated transportation oil of the supplementary energy supply heat energy of a kind of clean and effective.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is: the plumbing installation of a kind of heated transportation oil, including pipeline, the heat-insulation layer being wrapped in outside pipeline and the bracing frame of pipe end, the bottom of described pipeline is provided with media outlet, the top of described pipeline is provided with medium inlet, connect on media outlet and have a lower circulation pipe, the other end of lower circulation pipe is connected with the circulation import of solar thermal collector, lower circulation pipe is provided with a circulating pump, connect on medium inlet and have a upper circular tube, the other end of upper circular tube is connected with the loop exit of solar thermal collector, outer wall at described pipeline is provided with a temperature probe, a heat collector temperature probe it is provided with at the loop exit of described solar thermal collector, described circulating pump, temperature probe and heat collector temperature probe all electrically connect with a controller.
Preferably, described solar thermal collector is pressure-bearing type flat plate collector or pressure type vacuum cast heat collector.
The invention has the beneficial effects as follows:
Pipeline is connected with solar thermal collector, utilize the solar energy resources heat oil that petroleum pipeline enriches along the line, compensate the heat consumption during oil transportation, prevent because the temperature of oil declines, the mobility that viscosity rises and causes declines, the problem that transfer efficiency reduces, controller is utilized to realize automatic temperature difference circulation, oil is as circulatory mediator, without supplementing, winter can be antifreeze, and solar thermal collector is pressure-bearing type flat plate collector or pressure type vacuum cast heat collector, ensure that the bearing operation of whole device, efficient energy-saving.
