Description
The utility model relates to a kind of heating furnace, particularly a kind of natural gas vacuum furnace that is applicable to petroleum industry gas gathering and transportation field.Be the special equipment in the defeated field of petroleum industry collection, also can be used for the heating of other medium of oil-gas gathering and transportation field.
Heating main purpose to natural gas is exactly to suppress the generation of water synthetic, avoids the obstruction of equipment and pipeline.At present, suppress the gas hydrates generation and mainly contain two kinds of methods, the one, with equipment natural gas is heated, used equipment has: upright, horizontal tubular boiler, artesian water blind roaster, uncovered water jacket furnace.All there is defective in various degree in they, and are upright, horizontal tubular boiler is perishable, and service life is short, and service efficiency is low and operational administrative is complicated.The combustion system of artesian water blind roaster falls behind, and the thermal efficiency is low, and Fuel Consumption is big and bulky, and the transportation trouble is manipulated dangerous.Uncovered water jacket furnace is fouling on the outer wall of fire tube or coil pipe easily, and heat transfer coefficient is little, and steel consumption is big.The 2nd, add hydrate inhibitor, its deficiency is, and spray is inhomogeneous, and the inhibitor consumption is big, the cost height, and also toxicity is big, contaminated environment.
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of natural gas is heated to suppress the hydrate generation, adopt steam phase-change heat-exchange under vacuum state to come the heat(ing) coil heat exchanger, utilize the incoagulable gas of the boot sequence emptying system of vacuum valve and flow process, the heat-transfer effect ideal, the natural gas vacuum furnace of comfortable working environment.
The purpose of this utility model is achieved in that by body of heater, combustion system, controller, fuel conduit and constitutes, its structural feature is: body of heater is the pan shell type structure, bottom in the shell is provided with combustion system, top is provided with heat(ing) coil, outer surface be provided with its together with vacuum valve, the outside that fuel conduit is positioned at body of heater is connected with combustion system, is positioned at the outside of body of heater between integrated operation, and the controller of control body of heater operation is installed in it.
Described combustion system is two return structures, is made up of fire tube, the chamber of strile-bacing, smoke pipe, smoke box, and smoke pipe is a threaded flue.
Described natural gas heat(ing) coil is arranged in the vapor space of upper of furnace body.
Compared to existing technology, the utlity model has following advantage:
1, security of operation.The shell of this stove moves under negative pressure, does not bear any pressure basically, in case coil pipe breaks, high-pressure natural gas can be released rapidly by many heavy caliber vacuum valves rapidly.Natural gas is an indirect in addition, does not contact with naked light, does not have the possibility of detonation.
2, phase-change heat-exchange is higher more than 1.5 times than the heat transfer coefficient of convection current heat exchange, can reduce heating surface area effectively, greatly falls lower steel consumption.Adopt the threaded flue technology, make the heat exchange effect compare same specification and improved 40%, thereby make the body of heater volume small and exquisite, easy transportation and installation.
3, long service life.Middle heat transferring medium is closed operation, does not have the loss of middle heat transferring medium, does not need frequent moisturizing.Non-scaling, not oxide etch, long service life.
4, energy-conserving and environment-protective.The efficiency of combustion of the combustion system of this stove reaches more than 99%, and makes NO
x, CO
2Be effectively controlled NO
x, CO
2Concentration of emission well below the discharge standard of country.Thermal efficiency height.
5, multi-use.A natural gas vacuum furnace only needs the many groups of installation coil pipes, just can realize the multi-use function, can carry out many wells, the heating of individual well natural gas and life heat etc. simultaneously, saves investment, convenient management.
The explanation of accompanying drawing drawing:
Accompanying drawing is the utility model structural representation.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is made up of body of heater 5, combustion system 3, fuel conduit 4, controller 2, vacuum valve 6, operation room 1, body of heater 5 is the pan shell type structure, bottom in the shell is provided with combustion system, heating intermediate medium water, and top is vapor space and natural gas heat(ing) coil.Housing remains on the negative pressure of 0.0Mpa-0.3Mpa.Outer surface is provided with the vacuum valve 6 that is communicated with it, and fuel conduit 4 comprises that fuel gas pipeline, fuel pipe and oil gas mix the combustion pipeline, and the outside that is positioned at body of heater 5 is connected with combustion system 3, and combustion system 3 is two return structures, is made up of fire tube, the chamber of strile-bacing, smoke pipe, smoke box.Under the condition of gravity-flow ventilation, smoke pipe is selected light pipe for use.Under the pressure combustion mode, smoke pipe adopts the threaded flue through rolling screw-threads, makes the smoke convection heat exchange efficiency than the obvious raising of light pipe, and has significantly slowed down the sedimentation rate of the inner flue dust of body of heater.At areas without electricity, combustion system 3 is used no electric automatic control burner, and full-automatic combustion system is used in other area.1 outside that is positioned at body of heater between integrated operation is equipped with the controller 2 of control body of heater operation in it, controller 2 is to utilize operating liquid level, temperature, pressure signal, to combustion system 3 FEEDBACK CONTROL.Be divided into control on the spot, strange land control 7.Areas without electricity also can use no electric robot control system(RCS).Operation room 1 is an overall structure, is positioned at the outside of body of heater, dispatches from the factory with heating furnace 5 is self-contained respectively, at the scene can be in place rapidly, saved the set-up time, and improved working environment.
Operation principle of the present utility model: fuel such as combustion system combustion oil, gas, produce heat, make the medium boiling vaporization of shell bottom, the steam of generation runs into low-temperature coil, undergoes phase transition, condense into liquid state, discharge the latent heat of vaporization, the medium (natural gas) in the heat(ing) coil, the outer knot liquid that condenses of the pipe liquid level that falls back again, be heated once more, thereby finish whole heat exchange cyclic process.
The formation of vacuum and keeping: start combustion system, intermediate medium water is heated and is evaporated to steam in the shell, when its pressure during greater than external atmosphere pressure, vacuum valve is opened, and the dissolved oxygen in the empty G﹠W in the shell is disposed in the atmosphere, open the coil pipe flow process this moment again, part steam will with the rapid heat exchange of coil pipe wall, be condensed into water after discharging the latent heat of vaporization, make shell internal pressure moment reduce, vacuum valve cuts out, and shell is in negative pressure state.
