Definitions

  • the present invention relates to a further improvement thought with the purpose to obtain a better thermal efficiency, an environment deodorization and the regeneration of the chlorine-ethylene in a dry cleaning machine for clothes or fabrics of various types, as disclosed in the European Patent Application No.86104595.3 reference to which is hereby widely made for all subject matters not particularly described and specified hereinafter.
  • the invention as disclosed hereunder, illustrated in Figs. 1,2,3,4,5 and 6 covers a further improvement relating to the energy generating unit -Fig.5- in which, thanks to the addition of a second cold column and of a proper circuit controlled by the only central control unit, one comes to double the machine productivity, the consumption of energy being almost the same as for the previous version. Simultaneously, it has been possible to modify the circuit of the circulating air in the cleaning and drying phases, with a sensibly reduced consumption of electric energy and a more accurate adjustment of the temperature of the air circularing inside the barrel, which results in a better treatment of the product.
  • Fig. 1 represents a dry cleaning plant as disclosed and illustrated in the European Patent Aplication No. 86104505.3.
  • Fig. 2 shows in detail the heat and cold generating unit for recovery and regeneration of the chlorine-ethylene destined to cleaning, and for feeding the heat exchangers which are in operation during the cleaning phase, as already conceived by the same inventors before introducing the present improvement.
  • Fig. 5 shows the new heat and cold generating unit, now consisting of two cooling columns 25 and 25 ⁇ and of a warming one -26- each one being runned through by two types of pipe coils acting as heat exchangers; a first type is inserted in the bottom of the columns, where two of them are continuously fully immersed in the anti-freeze liquid and the third one in dyathermic oil. The second type is placed in the top of the column, wherein the liquid drops downwards and laps the pipe coil when such column is included in the circuit.
  • the heat and cold generating unit shown in Fig. 5 consists of a refrigerating compressor unit 22 which pressurizes the gas, Freon type or similar, sending it to the pipe coil 35, inside the column 26, through the tipe 23.
  • the pipe coil 35 rises,starting from the bottom of the column 26,in a series of tight spirals formed by a non-finned copper tube, filling almost completely the bottom of the column 26 so that in this area, constantly filled by dyathermic oil, this takes a volume sensibly lower than the half of the volume generated by the column 26.
  • the second section of the pipe coil 35 consists of a copper finned tube whose function is, besides diffusing the heat over a wider dispersing surface, also to keep the dyathermic oil falling downwards in contact, for a longer time, with the surface acting as a dispersant.
  • the Freon gas type already cooled, has reached the top of the column wherein is provided the distributing unit 49 of the inlet dyathermic oil, it enters the radiator 39 through the pipe 37 and therein it disperses in the ambient air the remaining calories through a first fan 40 which sucks the ambient air from the top side forcing it downwards through the radiator 39 wherein it goes to lap the column 26 from the outside.
  • a second fan 40 ⁇ sucks from the bottom the air which previously lapped the two columns 25 and 25 ⁇ , forcing it upwards through the radiator 39.
  • the pressurized gas brought to the ambient temperature, comes down through the pipe 41 so entering into the first plenum chamber (decanter) 42 and from here, through the pipe 43, into the second plenum chamber (decanter) 44, then reaching the expansion unit 45 wherein it is cooled in consequence of its expanding.
  • the melted Freon , past the expansion unit 45, is split up in two pipes having the same rate of flow, which enter into the columns 25 and 25 ⁇ .
  • each one of the two pipes is splitting in 4 pipes and having a section identical to the inlet one, so that the rate of flow which had already been halved past the expansion unit 45, is further reduced to one eigth in each duct.
  • the four pipers which are smooth, rise in the shape of a pipe coil inside each of the two columns 25 and 25 ⁇ and in this section they are continuously immersed in the anti-freeze liquid.
  • the four tubes rise in the shape of a coil pipe inside the column up to reaching the level of the anti-freeze liquid contained therein. From here the four pipes are connected two by two, in two pipes having a doubled section, also rising in the shape of a pipe coil up to reaching the top of the column wherein the shaped plate 49 is provided which causes the anti-freeze liquid, which is entering the column, to drop on the two-spiral-rising pipes, as shown in Fig. 4.
  • This unit allows to obtain a quantity of calories enough to regenerate the chlorine-ethylene and, in the following phase, to heat the cleaning air. Simultaneously, the refrigeration units are produced, which are enough both for the quick starting and for the life of phase, for the chlorine-ethylene regeneration and following cleaning phase.
  • the anti-freeze liquid, cooled inside one column, is intended only for chlorine-ethylene regeneration,the one of the other column being meant to condensate the chlorine-ethylene vapours during the cleaning and drying cycles. In such way the anti-freeze liquid is alternatively circulating inside the two columns.
  • the chlorine-ethylene regeneration phase is provided to be carried out. In consequence of that it is the cold column 25 the one destined to this phase, which has to start to operate as first.
  • the central control unit operates the two valves 59 and 59 ⁇ opening the one placed in the circuit of the column provided for chlorine-ethylene regeneration -valve 59- and closing the other one 59 ⁇ . Once the foreseen temperature is reached, the central control unit commands the starting of the chorine-ethylene regeneration phase opening simultaneously the valve 59 ⁇ which, alllowing the melted Freon to rise also inside the second column , sets this one for the following cleaning phase.
  • the melted Freon is circulating inside one only column, wherein the anti-freeze liquid is standstill, so bringing it in a shorter time to the lowest foreseen temperature. Later the melted Freon is circulating simultaneously inside both columns 25 and 35 ⁇ so that, when the anti-freeze liquid is circulating in 25, it is standstill in the bottom of the column 25 ⁇ , wherein the temperature of the two liquids - the Freon and the anti-freeze - is tending to equalize.
  • Chlorine-ethylene regeneration cycle Chlorine-ethylene regeneration cycle.
  • the motor driven pump 28 sends the heated dyathermic oil to the column 26, to the electrical heating element 29 provided inside the tank 6, upon closing of the valve 61 and opening of the valve 62, both allowing the dyathermic oil to enter into the duct 27 and to flow out from the duct 48 after heating of the element 29. Later, the motor driven pump 32 sucks the cooled liquid (anti-freeze)coming from the column 25, through the pipe coil 10 ⁇ the central control unit having opened the cocks 56 and 53 and closed the cocks 56 ⁇ and 53 ⁇ .
  • the central control unit actuates the motor driven pump 58 which transfers the chlorine-ethylene already used from the tank 2 to the tank 6, wherein it comes in contact with the heating element 29, already heated because the dyathermic oil flowed therein was at the highest temperature foreseen in the cycle.
  • the motor driven pump 58 On command of the central control unit, stops working and from now onwards the level of the chlorine-ethylene inside the tank 6 starts to decrease.
  • the central control unit actuates closing of the cork 62 and opening of the cork 61 at the same time, so the heating of the plate 29 stops and starts the heating of the radiator 19 ⁇ .
  • all the chlorine-ethylene inside the tank 6 is evaporating so that mud not polluted by chlorine-ethylene remain therein.
  • the central control unit closes the cocks 56 and 53 and opens the 56 ⁇ and 53 ⁇ ones.
  • the motor driven pump 32 stops its i ntake action from the column 25, through the pipe coil 10 ⁇ , and starts to intake from the column 25 ⁇ through the radiator 15.
  • the chlorine-ethylene regeneration phase is so finishing and the cleaning phase is starting.
  • the central control unit actuates the barrel 1 in which the garments to be cleaned have been introduced during chlorine-ethylene regeneration phase, actuating at the same time the motor driven pump 7 which transfers the regenerated chlorine-ethylene from the tank 4 to the barrel 1. Simultaneously, the central control unit actuates the electric fan 14 and closes at the top the flow deflecting valve 18 so that the air and the chlorine ethylene vapours, put in circulation by the above electro-fan, rise along the pipe 5, pass through the radiator 15 where they are cooled; the chlorine-ethylene vapours are so separated and, by their condensing, come down so entering again into the barrel 1.
  • the central control unit can adjust the temperature of the air flowing to the barrel 1. In fact, should a higher temperature be required, the central control unit opens the cock 64 so allowing the hot dyathermic oil, coming from the column 26, to pass also in the electrical heating element 30. Immediately afterwards, through the valve 18, it throttles the air flow letting a part to pass through the heating element 19 ⁇ and the reminder through the heating element 30 so that, since the same quantity of air is passing through a wider radiating surface, it takes off a bigger quantity of heat this resulting in an increase of the temperature since the flow rate is always the same.
  • the central control unit closes the cock 64, while continuing to allow the passage of a part of the air through the heating element 19 ⁇ and a part through the heating element 30 so that, this last being no longer heated, it yelds a lower quantity of heat up to the air which is so heated at a lower extent. In consequence of this, when the two flows again join together, they originate a lower temperature. It may so be realized how it is possible to obtain a very careful adjustment of the cleaning air and consequently a better work of the machine.
  • the central control unit commands the discharge of the chlorine-ethylene contained into the barrel 1, by opening the blowing off valve 55. Immediately afterwards, and after having opened the cock 64, it sends current to the resistance provided inside the duct 33, so the dyathermic oil passing through is warmed further, going to increase the temperature of the electrical heating element 30.
  • the central control unit through the flow deflecting valve 18,allows a part of the air to pass through the heating element 19 ⁇ and another part through the heating element 30 and in case the temperature has to be further increased the most of the air passes through the heating element 30by an adjustment of the flow deflecting valve 18.
  • the central control unit stops the motor driven pump 28 and closes the cocks 61 and 64, then stopping the motor driven pump 32 and closes the cocks 56 ⁇ and 53 ⁇ too; finally, since also the temperature of the clothes inside the barrel 1 has decreased, it stops the electric fan 14 and the rotating motion of the barrel 1. The attendant may so take off the cleaned clothes, the machine being already set for a further operating cycle.
