Vortex tube choke valve is vertically installed, low temperature dry gas outlet upper, high temperature moisture outlet under.
Operating principle of the present utility model is:
High sulfur-containing natural gas high pressure moisture enters vortex tube choke valve from the import of vortex tube choke valve, expand and separate by compression eddy flow, high sulfur-containing natural gas high pressure moisture is separated into low temperature dry gas and high temperature moisture, the high temperature moisture heat exchange that enters heat exchange segregator the heat exchange coil that low temperature dry gas enters heat exchange segregator from vortex tube choke valve upper top low temperature dry gas outlet and vortex tube choke valve lower part outlet separating out, condenses sedimentation in high temperature moisture, out enter reclaim line from heat exchange segregator outlet at bottom, low temperature dry gas after heat exchange enters heating furnace heating, it is defeated the high temperature dry gas becoming with the high temperature moisture that exports out from heat exchange segregator bottom high temperature dry gas after heating mixes.
The utility model has the advantages that:
The utility model combines vortex tube choke valve with heat exchange segregator, make full use of the high pressure energy of gas field well head, not only realized the effect of step-down throttling by vortex tube choke valve, and pressure energy is converted into the kinetic energy of natural gas, realize separating of high temperature moisture and low temperature dry gas, high temperature moisture and low temperature dry gas heat transfer process have been saved the needed cold energy of natural gas condensation.Moisture less low temperature dry gas is passed into heating furnace heating and can effectively weaken the corrosion of high sulfur-containing natural gas to Tube in Furnace, this positive role of having chosen to high sulfur-containing natural gas firing equipment material.While native system directly enters heating furnace heating with natural gas to be compared, and the temperature of low temperature dry gas is relatively low, and it is large that heat transfer temperature difference becomes, under identical heat transfer power and thermal transmittance condition, heat exchange area reduces, and this is conducive to reduce heating furnace structure size, realize miniaturization, reduce the equipment investment of heating furnace.
