Abstract
The utility model provides a subcooling device of shell and tube condenser, is located shell and tube condenser barrel bottom, supercooled liquid baffle level arrange with the barrel welding, baffling board subassembly and heat exchanger tube bundles II are settled to the below, the baffling board that relies on breach staggered arrangement to arrange increases the stroke of liquid refrigerants, the heat transfer time of secondary refrigerant in extension liquid refrigerants and the heat exchange tube, guarantee 6-10K's super -cooled rate, the operation of assurance system is stable, reliably.
Description
Technical field
The utility model relates to field of central air-conditioning Shell-tube Condenser, particularly relates to a kind of supercooling apparatus of Shell-tube Condenser.
Background technology
Condenser is one of four large parts of refrigerated air-conditioning system, and its effect is the liquid refrigerants high pressure gaseous refrigerant that compressor is discharged being condensed into temperature in high pressure in refrigeration (heat) circulation.General condenser will ensure the degree of supercooling of more than 5K, and system is just stable, reliable.The bottom of tradition Shell-tube Condenser is generally reserve few space to be used as reservoir or excessively colod-application, the utilization of its bottom space is also insufficient, in system, also additionally to install economizer additional effectively excessively cold to realize, although served cold effect, do not meet the requirement that society advocates energy-conserving and environment-protective.Though a lot of Shell-tube Condenser bottom has installed supercooling tube additional now, but do not play super cooling effect at all, without degree of supercooling, though having of having is cold, but the degree of supercooling provided does not reach 5K or more far away, the degree of supercooling that very difficult guarantee is more stable, so just causes the refrigerant heat transfer effect entering evaporimeter poor, thus refrigeration (heating) amount also just fails to give full play of.
Summary of the invention
The utility model provides a kind of supercooling apparatus of Shell-tube Condenser, be positioned at Shell-tube Condenser cylinder body bottom, horizontally disposed and the barrel soldering of supercooled liquid baffle plate, positioned beneath deflection plate assembly and heat-exchanging tube bundle II, effectively utilize cylinder body bottom space, rely on breach be staggered arrange deflection plate, increase the stroke of liquid refrigerants, extend the heat-exchange time of refrigerating medium in liquid refrigerants and heat-exchanging tube bundle II, ensure the degree of supercooling of 6 ~ 10K, ensure system run all right, reliably.
The utility model solves the technical scheme that its technical problem adopts: the supercooling apparatus providing a kind of Shell-tube Condenser, horizontally disposed and the barrel soldering of supercooled liquid baffle plate, positioned beneath deflection plate assembly and heat-exchanging tube bundle II, effectively utilize cylinder body bottom space, rely on breach be staggered arrange deflection plate, increase the stroke of liquid refrigerants, extend the heat-exchange time of refrigerating medium in liquid refrigerants and heat-exchanging tube bundle II, thus ensure that the degree of supercooling of condenser.
The utility model is made up of supercooled liquid baffle plate, deflection plate assembly and heat-exchanging tube bundle II, cylindrical shell circumferential interface is divided into a ~ m totally 12 intervals clockwise by clock and watch, supercooled liquid baffle plate is horizontally disposed, apart from both sides tube sheet 60 ~ 80mm, is positioned at cylindrical shell e ~ f interval also and barrel soldering; Supercooled liquid baffle plate positioned beneath deflection plate assembly and heat-exchanging tube bundle II, deflection plate assembly is made up of deflection plate, pull bar, distance sink tube and clamp nut, it is that symmetry axis is arranged symmetrically with, with several deflection plates of the layout that is staggered by breach at distance sink tube interval, both sides clamp nut is fixed that pull bar passes in turn with Barrel alignment; The liquid outlet pipe outside diameter d of spacing pipe range L >=2 times, to ensure the versatility of liquid refrigerants; Deflection plate is notched bowed shape, its breach area S >=liquid outlet sectional area F, and to reduce back liquid resistance, deflection plate cylindrical and cylindrical shell inner circle carry out interference fit, reduces the bypass circulation of liquid refrigerants; Heat-exchanging tube bundle II arranges turn 90 ° of modes with heat-exchanging tube bundle I above supercooled liquid baffle plate and is arranged on deflection plate assembly, and fixes with cylindrical shell both sides tube plate expanded-connecting.
The beneficial effects of the utility model are: the supercooling apparatus providing a kind of Shell-tube Condenser, be positioned at Shell-tube Condenser cylinder body bottom, rely on its gap position be staggered arrange deflection plate, increase the stroke of liquid refrigerants, extend the heat-exchange time of refrigerating medium in liquid refrigerants and heat-exchanging tube bundle II, ensure the degree of supercooling of 6 ~ 10K, ensure system run all right, reliable.
The utility model can be widely used in central air-conditioning refrigeration heat engine group condenser, comprises the condenser of dry type, full-liquid type, falling liquid film shell and tube exchanger unit.
