Embodiment 2
A kind of application for the device for improving existing space division liquid yield of the present embodiment, existing built space division generally comprise: Ice chest 1, main heat exchanger 2, former supercharger 5, former expanding machine 7, upper tower 3, lower tower 4, as shown in Figure 1, and former supercharger 5 expanded with former Machine 7 passes through axis connection.
The process flow of existing apparatus are as follows: air through the leading portions such as overcompression, pre-cooling, purifying processing after, pipeline GA-101's Pressure is~0.45MPaG, and temperature is~12-17 DEG C.Get rid of contained almost all carbon dioxide, water and part hydrocarbonization After closing object, it is divided into two parts.A part of GA-101 enters the main heat exchanger 2 in ice chest 1, after being cooled to liquefaction point, through pipeline GA- 102 enter lower tower 4.Another part GA-201 enters supercharger 5 and is compressed to 0.6~0.8MPaG, recycles the function of expanding machine release, ~40 DEG C are cooled to using cooler 6, passes through pipeline GA-202.The main heat exchanger 2 being sent into ice chest 1, from main heat exchanger 2 Portion extraction, by pipeline GA-204 extract out when temperature be -110 DEG C~-140 DEG C, into expanding machine 7 be expanded to pressure 0.01~ 0.05MPa, temperature are -175~-185 DEG C, and by pipeline GA-205, tower 3 participates in rectifying in feeding.The expansion process of expanding machine 7 It is the process externally done work using gas internal energy, by the rotation of expanding machine, expanding end high pressure (0.6~0.8MPaG) height The gas energy of temperature (- 110 DEG C~-140 DEG C) transfers out, and air itself is depressured (0.01~0.05MPa) cooling (- 175 ~-185 DEG C).Using entire ice chest as research system, the heat in ice chest 2 mainly passes through expanding machine 7 and is transmitted to outside ice chest, heat Outflow be exactly cooling capacity generation process.The cooling capacity part of generation maintains the thermal losses of ice chest, remainder to liquefied gas, Generate liquefied oxygen or nitrogen.
Since varying duty space division designs pipeline, heat exchanger and rectifying column in design with maximum tolerance in existing apparatus Tolerance is handled, in underload, flow velocity is relatively low in pipeline, and heat exchanger channel has part rich, and the load of rectifying column can also compare It is low.It is transformed based on this: drawing one air (~23000Nm from air into machine preceding pipeline GA-201 is increased3/ h) into Entering pipeline GA-301, is pressurized into plug-in supercharger 8, air can be pressurized (0.6~0.8MPaG) heating (30~80 DEG C), then After being cooled to~40 DEG C by cooler 9, pipeline GA-202 after former supercharger is entered by GA-302, is sent into main heat exchange after merging Device 2.In order to copy the surge of plug-in supercharger, pipeline GA-302 is connected to GA-301 by GA-303 pipeline, passes through adjusting Valve is controlled, and plays the role of protecting supercharger.The gas piping GA-204 extracted out in the middle part of main heat exchanger 2 meets branch GA- 304, take out portion of air (~23000Nm3/ h) by gap bridge 12, it is sent into plug-in expanding machine 10 and expands, air itself is depressured (0.01~0.05MPa) cools down (- 175~-185 DEG C).Heat is transmitted to outside ice chest by plug-in expanding machine 10, corresponding generation Cooling capacity enters the cold box system being made of plug-in small ice chest 11,12, ice chest 1 of passing a bridge.The cooling capacity of generation is except small 11 He of ice chest of maintenance It passes a bridge outside 12 cold damages, it can be all to produce liquid.23000Nm3The tolerance of/h can increase cooling capacity about 300~400kw, can increase Liquid yield, in terms of liquid oxygen: 3~3.7t/h.Generate considerable economic benefit.
The present embodiment utilizes the extra production capacity of air separation plant, by plug-in sled block (containing expanding machine, supercharger, cooler, small Ice chest, gap bridge) effectively increase the yield of space division liquid;Moreover, because being the extra production capacity using air separation plant, therefore to equipment Other component parts (such as: argon system, rare gas system) of stability and air separation plant etc. do not have an impact.
Specific embodiment of the utility model is described in detail above, but it is merely an example, this is practical new Type is not restricted to particular embodiments described above.To those skilled in the art, any pair of the utility model carries out Equivalent modifications and substitution also all among the scope of the utility model.Therefore, in the spirit and model for not departing from the utility model Lower made equal transformation and modification are enclosed, should all be covered in the scope of the utility model.
