The specific embodiment
The present invention utilizes the dry air compressor machine of self heat and air cooling in Fig. 1, the integral body that it is connected and is formed by absorption chiller system (1), air compressor system (2), swirl control cooling system (3) and insulation air drying bottle (4) four systems.
Air compressor machine drying means of the present invention is divided into two refrigeration systems and combines; Fig. 2 is configured to absorption refrigeration; Generator (17) in the absorption chiller system (1) links to each other with the exhaust high temperature coil pipe (13) of air compressor system (2); Continuous external insulation cold water tank (9) connection of the evaporimeter (10) of absorption chiller system (1) refrigeration piping (7), circulating pump (8), gas receiver (14) link to each other with insulation air drying bottle (4) and inner condensation aluminium flake (6); Insulation air drying bottle (4) is divided into two insulation air drying bottles (E) and (F) is divided into the two-stage drying; See Fig. 3; Provide heat to supply with generator (17) work from the high temperature that insulation air drying bottle (4) inhaled air to air compressor machine compression produces through exhaust high temperature coil pipe (13) by muffler (16) among Fig. 2; Make evaporimeter (10) refrigeration in the Absorption Refrigerator (1); Pass to the chilled water medium that is incubated cold water tank (9) after evaporimeter (10) freezes, gas receiver (14) and the air of insulation air drying bottle (4) in condensation aluminium flake (6) inside are cooled off through circulating pump (8) and refrigeration piping (7) by the chilled water medium, these air get into the middle processing and exchanging of gas receiver (14) by muffler (16) to air compressor machine behind the cool drying and become dry air supply external equipment to use in insulation air drying bottle (4); Be equipped with dewatering outlet (15) at gas receiver (14) and insulation air drying bottle (4) bottom, the condensed water that is produced is by discharge.
Fig. 3 is swirl control cooling system (3); This part is an auxiliary cooling; Swirl control cooling system (3) is connected with 2 insulation air drying bottles (4) with swirl control cooling system (3) through exhaust high temperature coil pipe (13) to the magnetic valve (19) of air compressor system (2), and it is that two-stage is dry (F) for (E) that insulation air drying bottle (4) is established 2.Described insulation air drying bottle (4) is because during start work just; Air compressor machine does not produce heat; Absorption chiller system (1) can't be worked; At this moment the air compressor machine magnetic valve is opened, and pressure-air directly gets into swirl control cooling system (3) and through cold air control valve (18) certain temperature is set and cooling off of condensation aluminium flake (6) in insulation air drying bottle (4) made to suck air dry, and most dry air gets in the gas receiver (14) through air compressor machine behind the air cool drying; Another part compressed air also cools off condensation aluminium flake (6) at swirl control cooling system (3); By the time exhaust high temperature coil pipe (13) heat rising absorption chiller system (1) work, magnetic valve (19) cuts out in the time of can reaching the temperature of regulation, and swirl control cooling system (3) stops; Air compressor machine gets into normal operative condition, plays interim compensation heat effect in order to prevent the air compressor machine start-stop and by generator (17), to be provided with electric heater (12) with the gas size when uneven.
Two kinds of refrigeration system work that should the drying air compressor machine of the present invention are originally: a kind ofly be absorption refrigeration, system is that ammonia, water, three kinds of materials of helium are formed, and it is the generator (17) that utilizes the heat absorption chiller system (1) that the air compressor machine blast pipe produces; Make the concentrated ammonia liquor boiling after the heating; The ammonia steam that is evaporated is through the distiller condensation, and steam returns absorber (11), and ammonia is condensed into liquid ammonia through conductive fluid liquid pipework condensation device; Then in evaporimeter (10) import department and helium mix; Because the different ammonia of dividing potential drop spread in helium from ammoniacal liquor tempestuously, evaporimeter (10) temperature is reduced, liquefied ammonia is depressed low branch the in evaporimeter (10); The ammonia, the helium in the helium gas mixture that generate discharge ammonia in absorber (11); Absorbed through the conductive fluid pipe heat release in the absorber (11) by water, liquor ammoniae fortis gets into generator (17) again, because variation physically; Form each absorption refrigeration, exothermal reaction process, the present invention be provided with in evaporimeter (10) periphery insulation cold water tank (9) inner refrigerant be aqueous medium pass through circulating pump (8) to gas receiver (14) be incubated air drying bottle (4) circularly cooling and be exchanged into dry air.
Another kind is that the swirl control cooling system is made up of parts such as vortex generator overcoat, inner core, regulating spool, adjusting bonnets; The part compressed air that its principle of swirl control cooling system (3) is simply used air compressor machine itself is as power source; Utilize its pressure differential of compressed air to see Fig. 3 accompanying drawing, after compressed air sprayed into the vortex tube minor air cell from A, the air communication excessively high speed was rotating and is flowing to vortex tube hot gas end B outlet; Part air communication is crossed control valve and is flowed out; After remaining gas is stopped, with same rotating speed reverse rotation, and flow to vortex tube cold air end C at former air-flow inner ring.In this process, two bursts of air-flow generation heat exchanges, interior ring air-flow becomes terribly cold; Flow out from C, it is awfully hot that the outer shroud air-flow then becomes, and flows out from B; The big I of the temperature of cold airflow and flow is through regulating the gate control of vortex tube hot gas end valve; It is high more that vortex tube hot gas brings out the gas ratio, and then the temperature of vortex tube cold air end air-flow is just low more, the also corresponding minimizing of flow; The present invention utilizes these principles to use wireway that this extremely low cold gas stream is induced one the cooling of the condensation aluminium flake (6) in the insulation air drying bottle (4) cooling is exchanged into dry air for about-40 ℃, again with in these air that are dried suction air compressor system gas receivers (14).
The present invention is equipped with temperature controller at two insulations of evaporimeter, front end cold water tank, gas receiver, electrical heating, the swirl control cooling system of absorption chiller system; Simultaneously the swirl control cooling system also is provided with magnetic valve, these control circuits simple with each system's unit circuit be that known basic technology no longer marks (figure summary).
