A simple and practical recovery device for separating the freon from the adsorbent and directly compressing it is designed for various equipments using freon, and a portable tool box with multiple functions of recovering, vacuumizing and quantitatively filling freon is also designed.
Description
The invention belongs to refrigeration technology field, the innovation be with economical and practical method separate and the purification entrained air after fluorine Lyons and propose a kind of have the recovery function fluorine Lyons take out the notes machine.
Fluorine Lyons is fluorine, the chlorine of saturated hydrocarbon, the general name of br-derivatives, with its special thermodynamic character and strong molten oiliness, is used widely in fields such as cold system, washings.But along with development of science and technology, people recognize this colourless, no bromine, do not burn, and it is to destroy atmospheric ozone layer that expensive halides is competed.A kind of compound that is difficult to decompose of harm earth environment.Do not finding before the substitute, recycling reduces discharge capacity as far as possible, economically with environmental protection on all highly significant.
In semi-open working environments such as washing facility, fluorine Lyons is to be gaseous state and to be mixed with a large amount of air during as cleaning agent, from thermodynamic properties, the liquidus temperature of each gas componant of fluorine Lyons and air falls far short under uniform pressure, the purification of can liquefying, problem is to drop to a large amount of mists at normal pressure below-30 ℃, expend lot of energy, does not also have a kind of economical and practical retracting device to use on washing facility so far.All be after cleaning, to open the operating room to allow fluorine Lyons gas diffuse away.In addition in the maintenance refrigeration plant, the circulatory system that all Kaifeng are closed, chlorofluoromethane refrigerant diffuses away at once, not only wasted but also atmosphere pollution, be badly in need of a kind of maintenance tool that can reclaim fluorine Lyons, can be during maintenance first this device of income in the fluorine Lyons in the refrigeration plant, can vacuumize protofluorine Lyons but also injection after purifying not only after waiting to keep in repair refrigeration plant.There were several experimental provisions to realize this recovery in the past, but also do not come out as a kind of product multiple functional, easy and simple to handle.
The natural rubber of finding the micropore bulk of sulfidization molding in practice has very strong suction-operated to fluorine Lyons, its volume and weight will increase several times in the closed container that fluorine steam is arranged, and in atmosphere resilient, has desorption, desorption rate can be accelerated under vacuum state, and little to other gas effect.The present invention proposes with the block natural rubber of micropore or other resin compound and make adsorbent, fluorine Lyons steam in the mist can be come out in initial gross separation, then just utilizing again after the steam cooling after this concentrating, pressurization, liquefaction, the filtration oil removing, as long as the purpose that energy consumption seldom and easy equipment just can reach recovery.
Shown in Figure 1 is this schematic representation of apparatus, (1) is the operating room that adds a cover among the figure, (2) be inlet valve, (3) be the sealed cabinet of dress adsorbent, (4) be a kind of or its structure of gating element shuttle valve is seen Fig. 3, (5) be piston compressor, (6) be the magnetic valve of dress timer, (7) be condenser, (8) are choke valves, and (9) are its inner bag dress agent for storage of coldness of flooded evaporator, (10) be gas charge formula heating power expansion valve, (11) be vent valve, (12) are pressure switches, and (13) are steam injection valves.Washing finishes when the operating room, when opening inlet valve, and last mist in the very fast inspiration of the absorption cabinet operating room that has been in vacuum of circulating, the size of cabinet is decided with the capacity of operating room, through certain hour, fluorine steam is just given adsorbents adsorb behind the valve of pass, and air is just stayed the epicoele of cabinet.At this moment open compressor, magnetic valve is energising simultaneously also, valve is in evacuate position and extracts the air that is not adsorbed in the cabinet out, by the time fixed time promptly just arranged air, the magnetic valve outage, valve is in shown position, and the compressor fluorine steam that desorption in the cabinet is come out that works on is pressed into the condenser cooling, enters evaporimeter by choke valve.Reach certain vacuum when adsorbing cabinet, the pressure on shuttle valve two limits changes, and spool is action just, seals the outlet of adsorbing cabinet and the outlet of opening evaporimeter, and gas is through compressor cycle.At this moment the amount of fluorine Lyons steam is also few and be mixed with little air, and this circulation mainly is the gas swelling heat absorption.Shuttle valve but also action when not only the fluorine steam-to-vacuum degree that makes new advances of desorption reduces in the absorption cabinet are so just constantly extracted the fluorine Lyons steam that reaches the evaporimeter discharge that desorption goes out and are circulated.Just may be compressed into liquid state when quantity of steam increases, this system just is the evaporation heat absorption, and the temperature in the evaporimeter constantly reduces.Arrived predetermined temperature value; the temperature-sensitive bag internal pressure of the heating power expansion valve in exit reduces; valve is just closed; the absorption cabinet just is in the state of bleeding fully, has arrived the certain hour desorption and has finished and just can shut down, and fluorine steam all is pressed in the cryogenic vaporizer and liquefies; press vent valve and can drain air; if at this moment temperature is 0 ℃ in the evaporimeter, the about 0.3MPa of the pressure of R12, the about 0.5MPa of the pressure of R22.The absorption cabinet has been in vacuum state can carry out next circulation recovery again.The working time of compressor and the unlatching of valve can be carried out automatically by electric sequential control.In order to improve the exhaust capacity of compressor, reduce the molten oil in fluorine Lyons, on the piston of reciprocating compressor, added two piston rings as shown in Figure 2 with the angular cut of polytetrafluoroethylene (PTFE) system, " O " type circle that the ring heelpiece is suppressed with anti-fluorubber, rotor-type compressor just needn't be reequiped.
On the equipment that has, there is no need must be fluorine Lyons steam liquefaction, if the absorption back a preliminary and air separation, it is just standby that the fluorine steam that concentration has improved is compressed into gas storage tank; And in reclaiming refrigeration plant during as fluorine Lyons of cold-producing medium, its purity is very high, if when reclaiming entrained air not, just needn't add the absorption order and directly introduce retracting device.Flexible Application as the case may be in a word, introduce the embodiment of the retracting device of two kinds of different operating occasions below:
Shown in Figure 4 is a kind of schematic diagram that is contained in the device for recycling freon in dry cleaner or other the part surface cleaning machine, (1) is the operating room that adds top cover among the figure, (2) be inlet valve, (3) be the absorption cabinet of dress microcellular rubber particle, (4) be that fluorine Lyons replenishes jar, (5) be compressor, (6) be magnetic valve, (9) be vapour storage tank, in turn on pump emptying that different with Fig. 1 the is absorption cabinet behind the air, it is standby that the fluorine steam that direct extraction desorption comes out is pressed into vapour storage tank, simplified device like this and can further reduce energy consumption again.Compressor selects for use gettering ability strong, has rotator type or the reciprocating compressor used on the refrigeration plant of oily separation ability.
Shown in Figure 5 is a kind of schematic diagram that reclaims cold-producing medium fluorine Lyons, (21) are cams among the figure, (22) be two two position three-way valves, (23) be the rotator type freezer compressor, (24) are pressure vacuum gauges, and (25) are condensers, (26) be the graduated cylinder of band groove, (27) be the screw-type choke valve, (28) are the seal nipples of band pipe cutter, and (29) are the refrigerators that needs maintenance.Fig. 8 is the cutaway view of pipe cutter, and Fig. 9 is this Unit Installation figure.Fitting sleeve is annotated on the fluorine pipe at the freezer compressor of need maintenance, screwing hermetic end cap cushion rubber just encases copper pipe, cam is forwarded to Fig. 6 position, just take out the air in the pipeline behind the turn on pump, forward Fig. 5 again to and reclaim the position, hold the urceolus of Fig. 8 pipe cutter, plate changes cutting head, three are cut the just relative copper pipe rotation of wheel and cut and cut off copper pipe under the guiding of sleeve inner cone, fluorine Lyons in the refrigerator pipeline just is drawn into retracting device, by condenser, and choke valve and enter graduated cylinder, the vent valve of pressing on the tube can be drained air, and start a period of time just can all be pressed into graduated cylinder to fluorine Lyons.Turning handle is also shut down to Fig. 6 position and just has been stored in the graduated cylinder.Keep in repair as refrigerator; start shooting in Fig. 6 position; just can take out the air in the deicing case; forwarding Fig. 7 position to shuts down; refrigerator is just slowly injected in fluorine Lyons in the graduated cylinder; cylindrical shell is carved with R12 and the specific volume of R22 when different temperatures, and the temperature during with reference to operation is just known how many amounts of having injected, and also is suitable for the recovery and the perfusion of air-conditioning equipment R22 cold-producing medium.Replenishment valve under tube can also can vacuumize, annotate fluorine work separately by external standby liquid storage bottle.Can adopt the secondary exhaust method in order to overcome the compressor suction not as lacking of vavuum pump, promptly be evacuated to the certain vacuum degree after, change hands handle to Fig. 7 position, put some fluorine steam and advance in the maintenance system, forward Fig. 6 position again to and bleed, can improve intestine evacuation velocity like this.
