Abstract
Disclosed is an integral freeze drying machine, which enabless that two filters is equipped in a body of the freeze drying machine, adopts cope pipes and fins to expansively form a three-in-one heat exchanger with three functions of both an advanced precooler, a heat exchanger and a condenser, and a rectangle evaporator, makes the volume of the integral freeze drying machine contracted and the structure compacted, the air flow spread uniformly in the course of heat exchange, small air-resistance and better effect of heat transfer, basing on the prior freeze drying machine. The device only need to insert a compressed air to an inlet of the monolithic freeze drying machine without the additional filter during the use, then can achieve the cleaned air from an outlet. The design enables the connecting length of air pipes shorten, the ratio of the cold loss and leakage decreased, the effectiveness increased.
Description
The technical field cooling driers is a frozen compressed air dryer, is use in gas purification process the most extensive, and is most economical, reliable device.What the design related to is air-cooled cooling driers, is freeze drying system, filtration system, the monoblock type cooling driers of refrigerant system design within a casing with cooling driers.
The composition of background technology tradition cooling driers generally includes only the freeze drying system: preposition forecooler, heat exchanger, condenser, induced-draught fan, evaporimeter; And refrigeration system: cold medium compressor, heating power expansion valve, reservoir etc.In use must former and later two filters of configuration, compressed air enters traditional cooling driers and handles after filtering through preceding HC level filter, and the air that comes out from cooling driers can obtain the general compressed air that purifies requirement again through back HT level filter.The drawback that exists is: 1, the front and back filter is installed by the user is on-the-spot, must increase leak rate and cold damage with two external pipelines; 2, preposition forecooler, heat exchanger, the condenser in the cooling driers all is that independent portion machine is assembled, and volume is big, and leak rate is big, the cost height; 3, evaporimeter is a horizontal garden cartridge type, and heat transfer efficiency is subjected to air from the gap bypass and corresponding reducing, and belongs to pressure vessel, and is difficult in safety and monitoring.
Summary of the invention is for overcoming above-mentioned drawback, and the utility model has designed a kind of monoblock type cooling driers, and this monoblock type cooling driers comprises: preposition forecooler, heat exchanger, condenser, induced-draught fan, evaporimeter, reservoir, cold medium compressor, heating power expansion valve; Two filters or two parts that filtering function is arranged are housed in the monoblock type cooling driers, and two filters or two have the parts of filtering function to be installed in the inlet end and the outlet side of monoblock type cooling driers respectively.The user promptly finishes installation as long as connect the inlet, outlet end.
With copper pipe and fin expanded joint make have both preposition forecooler is arranged, the three-in-one heat exchanger of heat exchanger and three kinds of functions of condenser substitutes preposition forecooler, heat exchanger and condenser in the monoblock type cooling driers.Make monoblock type cooling driers internal structure compactness, volume reduces, and has alleviated connection management, has improved heat transfer efficiency, has reduced manufacturing cost.
Evaporimeter in the monoblock type cooling driers adopts is the rectangle evaporimeter made from copper pipe and fin expanded joint of vertical assembling.Improve heat transfer efficiency, also freed the pressure vessel safety monitoring that traditional garden cartridge type evaporimeter exists.
Description of drawings Fig. 1 is a monoblock type cooling driers profile schematic diagram: compressed air inlet (10), clean air outlet (11), induced-draught fan (2);
Fig. 2 arranges (overlooking) schematic diagram for the monoblock type cooling driers: three-in-one heat exchanger (1), hair-dryer (2), outer case (3), rectangle evaporimeter (4), filter (5), (8), reservoir (6), cold medium compressor (7), heating power expansion valve (9).
The specific embodiment is further described the utility model below in conjunction with embodiment.
As shown in Figure 1 and Figure 2.Present embodiment comprises the freeze drying system that is made up of three-in-one heat exchanger (1), induced-draught fan (2), evaporimeter (4); The refrigeration system that filtration system that filter (5), (8) are formed and cold medium compressor (7), heating power expansion valve (9), reservoir (6) are formed.Three systems interconnect, and reliably are installed within the casing (3).
Three-in-one heat exchanger (1) be copper pipe and fin expanded joint form have both the function that preposition forecooler, heat exchanger and condenser are arranged, simplify the structure, dwindled volume, improved heat exchange efficiency, be a kind of novel heat exchange structure.
Evaporimeter (4) is the rectangle evaporimeter that copper pipe and fin expanded joint form, and has heat exchange efficiency height, advantage that volume is little.Vertical being assemblied within the casing (3).
Specific implementation process: compressed air enters the built-in filter of monoblock type cooling driers (8) from air inlet pipe, after the filtration of HC level, discharge from interior conduit, enter the air inlet pipe d of the preposition forecooler in the three-in-one heat exchanger (1), compressed air precooling in preposition forecooler after the HC level is filtered, the part condensed water is separated out in the compressed air, the air that has reduced water content enters evaporimeter (4) after blast pipe c discharges, Chang Ludian can reach-20 ℃, separate out condensed water again, the water content Cryogenic air seldom of discharging from evaporimeter (4) enters the interior heat exchanger air inlet pipe b of three-in-one heat exchanger, compressed air after the heat exchange enters filter (5), the air dust-laden particle diameter＜1 μ m that discharges after the HT level is filtered, oil content＜1ppm meets the requirement of general Purge gas.
The implementation process of refrigeration system: cold-producing medium extrudes the condenser that enters three-in-one heat exchanger (1) from cold medium compressor (7), the cooling back is to reservoir (6), throttling obtains low temperature through heating power expansion valve (9), after get back to cold medium compressor (7) after entering evaporimeter (4) and compressed air heat exchange, finish a kind of refrigeration cycle.
For understanding each operating mode at any time, the pressure and temperature of compressed air operation all there is distinct demonstration, so that grasp at any time.
The design's monoblock type cooling driers need only go out pipe with compressed air and be connected with monoblock type cooling driers air inlet pipe (10), and what monoblock type cooling driers escape pipe (11) was discharged is exactly to meet the air that general purification requires.If any higher purification requirement, then can be at the higher filter (fine filter) of monoblock type cooling driers escape pipe (11) back adjunction rank.
Condensed water in three-in-one heat exchanger, evaporimeter, the filter is by outside automatic drain valve or the manual drainage valve discharge machine.
Three-in-one heat exchanger (1) is forced air draft by the induced-draught fan (2) that is installed on the boxboard, improving the heat exchange efficiency of preposition forecooler, heat exchanger and condenser, thereby obtains best refrigerating effect.
The design has following advantage: 1, compact conformation, small volume, easy for installation, reliable operation; 2, Air-flow is evenly distributed in heat exchanging process, and vapour lock is little, and heat-transfer effect is good; 3, shorten the pipeline connecting length, Cold damage, slip reduce.
