Pri plnění sifónových bombičiek kvapalným oxidom uhličitým na automatizovanom rotorovom stroji dochádza až k 40 %-nej nepodarkoýostl· y dósledku nedostatočného naplnenia bómbičky. Příčinou tohoto javu je voda přítomná v kvapalnom oxide uhličitom, ktorá pri expanzii al lokálnom podchladení počas plnenia bombiíčky zamrza v mieste s najvačším lokálnym pdporom. Tým sa v tomto mieste znižuje účinný prierez cesty pri dávkovaní oxidu uhličitého a dochádza k nedostatečnému naplneniu sifónovej bombičky. Kvapalný oxid uhličitý sa dávkuje zo zásobníka, kde sa udržiava pri teplotách —20 až —40 °C a odpovedajúcom tlaku, cez predohrievač do plniaceho stroja. Pri vstupe do plniaceho stroja sa udržiava teplota oxidu uhličitého na 16 až 18 QC a tlak 6,8 až 8,0 MPa. Kvapalný oxid uhličitý v zásobníku obsahuje rozpuštěnu vodu a jemne dispergované čiastočky ladu, ktoré sa pri ohrievaní CO2 před plněním do bombičiek čiastočne alebo úplné roztopia.When filling the siphon cartridges with liquid carbon dioxide on an automated rotor machine, up to 40% of the undercrowding occurs due to insufficient filling of the bomb. The cause of this phenomenon is the water present in the liquid carbon dioxide, which, when expanded and localized undercooling during the filling of the cartridge, freezes at the site with the greatest local support. This reduces the effective cross-sectional area at the point of carbon dioxide dosing and inadequates the siphon cartridge. Liquid carbon dioxide is fed from the reservoir, where it is maintained at temperatures of -20 to -40 ° C and the corresponding pressure, through a preheater to the filling machine. On entry into the filling machine to maintain the temperature of carbon dioxide at 16-18 Q C and a pressure of 6.8 to 8.0 MPa. The liquid carbon dioxide in the reservoir contains dissolved water and finely dispersed ice particles which melt partially or completely when the CO2 is heated before being filled into the cylinders.
Vyššie uvedené nedostatky možno* odstrániť spósobom oddelenia tuhých podielov vody z kvapalného oxidu, uhličitého filtráciou podlá vynálezu, kterého podstata spočívá v tom, že filtrácia prebieha pri teplote 223 až 273,16 °K, pričom zachytené tuhé podiely vody sa po skončení filtrácie a ohriati na teplotu aspoň 273,2 °K roztopia a podiel kvapalnej vody nerozpustný v kvapalnotn oxide uhličitom sa oddělí sedimentáciou.The above-mentioned drawbacks can be eliminated by separating the solids of water from the liquid carbon dioxide by filtration according to the invention, characterized in that the filtration takes place at a temperature of 223 to 273.16 ° K, whereby the collected solids of water are filtered and heated. to a temperature of at least 273.2 ° K and the fraction of liquid water insoluble in liquid carbon dioxide is separated by sedimentation.
Zariadenie na uskutočnenie spósobu podlá vynálezu pozostávajúce z filtračnej přepážky, uzavretej dvomi vekami, má jedno veko opatřené odkalovacím ventilom a rúrkou pre přívod suroviny a protilehlé veko opatřené rúrkou pre odvod filtrátu.An apparatus for carrying out the method according to the invention, comprising a two-lid filter screen, has one lid provided with a sludge valve and a feed tube and an opposing lid provided with a filtrate discharge tube.
Filtračná přepážka móže byť orientovaná horizontálně, vertikálně, alebo šikmo a má tvar rovinnej, valcovej alebo gulovej plochy, alebo kombináciu týchto ploch.The filter baffle may be oriented horizontally, vertically or obliquely and has the shape of a planar, cylindrical or spherical surface, or a combination thereof.
Riešením podlá vynálezu sa dosiahne jednoduché oddelenie tuhých podielov vody z kvapalného oxidu uhličitého. V porovnaní s použitím klasického filtračného zariadenia, sa nevyžaduje náročné odstraňovanie filtračného koláča. Po ukončení filtrácie a odstavení zariadenia sa zariadenie ohřeje na teplotu okolia, pričom sa zachytené krystalky 1'adu roztopia a vo formě kvapalnej vody stečú do* zberača odkial sa voda jednoducho vypustí do kanála. Zariadenie je konštrukčne a -výrobně nenáročné a nevyžaduje si zvláštnu obsluhu. V případe nepretržitej prevádzky možno použiť dve alebo viac paralelné připojených zariadení, z ktorých jedno pracuje. Použitie spósobu a zariadenia podfa vynálezu před plněním sifonových bombičiek umožňuje stabilizovat naplnenie kombičlek a tým znížiť nepodarkovosť.The solution according to the invention achieves simple separation of solids of water from liquid carbon dioxide. Compared to the use of a conventional filter device, the demanding removal of the filter cake is not required. After filtering and shutting down the device, the device is warmed to ambient temperature, whereupon the collected crystals 1 ' The device is not demanding in terms of construction and manufacture and does not require special operation. In the case of continuous operation, two or more parallel connected devices may be used, one of which works. The use of the method and apparatus of the present invention prior to filling the siphon cartridges makes it possible to stabilize the filling of the combi and thus reduce the under-yield.
Na připojených výkresoch sú znázorněné dva příklady zariadenia na oddelovanie tuhých podielov vody z kvapalného* oxidu uhličitého. Na obr. 1 je schéma zariadenia s horizontálnem filtračnou přepážkou a na obr. 2 schéma zariadenia so zvislou filtračnou přepážkou.Two examples of a device for separating solids of water from liquid carbon dioxide are shown in the accompanying drawings. In FIG. 1 is a diagram of a device with a horizontal filter partition and FIG. 2 is a diagram of a device with a vertical filter screen.
Zariadenie podlá vynálezu pozostáva z veka 5 opatřeného odvzdušňovacím ventilom 7 a rúrkou pre odvod filtrátu 6 a veka 2, opatřeného odkalovacím ventilom 4 a rúrkou pre přívod suroviny 3. Medzi vekami je umiestnená filtračná přepážka 1.The device according to the invention consists of a lid 5 provided with a venting valve 7 and a tube for draining the filtrate 6 and a lid 2 equipped with a blow-off valve 4 and a tube for supplying raw material 3. A filter partition 1 is arranged between the lids.
Rúrkou 3 sa pri teplotách —50 až 0 °C do zariadenia privádza kvapalný oxid uhličitý obsahujúci tuhé podiely vody, ktoré sa zachytla na filtračnej prepážke 1. Kvapalný CO2 zbavený tuhých podielov prechádza do veka 5, odkial sa odvádza rúrkou 6. V priebehu filtrácie sa na filtračnej prepážke hromadia tuhé podiely vody v dósledku čoho rastie strata tlaku v zariadení. Po dosiahnutí zvolenej hodnoty straty tlaku sa zariadenie odstaví, pričom sa začne ohrievať na teplotu okolia. Po dosiahnutí teploty vyššej ako 0 C sa tuhé podiely vody topia a kvapalné podiely vody nerozpustné v oxide uhličitom sedimentujú na dno veka 2, odkial sa odpúštajú odkalovacím ventilom 4.Liquid carbon dioxide containing solids of water, which is trapped on the filter baffle 1, is fed into the apparatus at a temperature of -50 to 0 ° C through the tube 3. solid particles of water accumulate on the filter screen as a result of pressure loss in the plant. When the selected pressure loss value is reached, the device is shut down and begins to warm to ambient temperature. Upon reaching a temperature above 0 ° C, the solids of water are melted and the liquid portions of water insoluble in carbon dioxide sediment to the bottom of the lid 2 from where they are discharged by the blowdown valve 4.
Zariadením podfa vynálezu možno oddělit tuhé podiely vody z kvapalného CO2 aj pri teplotách vyšších ako 0 °C. S ohladom na to, že pri teplotách vyšších ako 0 °C sa časť vody roztopí a nezachytí sa na filtračnej prepážke, nie je oddelenie vody z kvapalného oxidu uhličitého pri teplotách! vyšších ako 0 °C tak efektívne ako pri teplotách pod bodom mrazu vody.By means of the device according to the invention, solids of water can be separated from liquid CO2 even at temperatures above 0 ° C. With regard to the fact that at temperatures above 0 ° C, some of the water melts and does not get trapped on the filter partition, there is no separation of water from liquid carbon dioxide at temperatures! higher than 0 ° C as efficient as below freezing temperatures.
