Description
Pulverförmige Perverbindungen enthaltende Waschmittel Perverbindungen enthaltende pule erförmige Waschmittel werden meistenteils durch mechanisches Vermischen der Einzelbestandteile, die verschiedene spezifische Gewichte aufweisen, erhalten. Auf Grund dieser Tatsache kann unter Umständen leicht eine Entmischung . der Einzelbestandteile eintreten, was insbesondere bei der Anwendung der Wasch- und Reinigungsmittel von Nachteil sein kann. Es "sind zwar Waschmittel bekannt, die aus verschiedenen Einzelbestand; teilen bestehen und dennoch ein einheitliches Produkt darstellen. Derartige einheitliche Stoffmischungen werden. beispielsweise durch Zerstäubung von Lösungen, Suspensionen oder Schmelzen der einzelnen Waschmittelbestandteile in Zerstäubungsvorrichtungen hergestellt. Hierbei. werden voluminöse Pulver erhalten., die staubfrei sind und eine gleichmäßige Korngröße und Struktur aufweisen. Es ist jedoch nicht möglich, nach Verfahren der vorgenannten Art Waschmittel in Pulverform herzustellen, die Perverbindungen enthalten, da, um ein trockenes Waschpulver zu erhalten, das Gut heiß zerstäubt werden muß. Bei einer Zerstäubung von heißen Lösungen, Suspensionen oder Schmelzen, die außer den übrigen Waschmittelbestandteilen auch bereits Perv erbindun.gen enthalten, werden aber infolge der bei dem Zerstäuhungsvorgang erforderlichen hohen Temperatur und durch die Anwesenheit von Wasser die Perverbindungen zersetzt, wobei ihr wirksamer Bestandteil, der aktive Sauerstoff, verlorengeht. Aus diesem Grunde -,var man auch bei der 'Verwendung von Zerstäubungsprodukten darauf angewiesen, diese nachträglich mit den Perverbindungen zu vermischen, wodurch wiederum ein Stoffgemisch mit verschiedenen spezifischen Gewichten und den damit verbundenen Nachteilen erhalten wurde. Es wurde nun. gefunden, daß .man Perverbindungen enthaltende Waschmittel in Forin 'eines einheitlichen Pulvers von gleichmäßiger Korngröße und Struktur auf dem Wege der Zerstäubungstrocknung in einem Arbeitsgang dadurch erhält, daß man heiße Lösungen, Suspensionen oder Schmelzen .der Waschmittelbestandteile in Abwesenheit der Perverbindungen in Zerstäubungsvorr ichtungen in einem Gasstrom in Form eines Hohlkegels zerstäubt und gleichzeitig in den oberen: inneren Teil des' von den zerstäubten Teilchen gebildeten Hohlkegels die jeweils zur Verwendung gelangenden. Perveibindungen in pulverförmigem Zustand hinein-sprüht. Beim. Eintritt der fein zerstäubten Lösung in -den Gasstrom wird der größte Teil des Wassers sofort verdampft. Die zerstäubten Teilchen treffen in noch halbfeuchtem Zustand mit den entgegengeblasenen festen Teilchen der Perverbindungen zusammen und umschließen diese wie eine Isölierschicht. Dadurch sind die einzelnen Teilchen der Perv erbindungen gegen die Einwirkung auch eines heißen, wasserdampfhaltigen Gasstromes und der damit verursachten Zersetzung weitgehend geschützt. Man erhält auf diese Weise ein einheitliches. Pulver, bei -dem die einzelnen Teilchen der Perverbindüngen nicht mehr neben .den übrigen -Waschmittelbestandteilen liegen, sondern in diese eingelagert bzw. mit diesen verkittet sind. Die neuen. Wasch- und Reinigungsmittel sind' daher Produkte mit einheitlichem -spezifischem Gewicht, die sich nicht entmischen können.Detergents containing powdered per-compounds per-compounds containing coil-shaped detergents are mostly produced by mechanical mixing of the individual components that have different specific weights. Due to this fact, a segregation can easily occur under certain circumstances. of the individual components occur, which is especially true when using detergents and cleaning agents from Can be disadvantage. There are "detergents known that consist of different individual items; parts exist and still represent a uniform product. Such uniform Mixtures of substances are. for example by atomizing solutions, suspensions or melting the individual detergent constituents in atomizing devices manufactured. Here. voluminous powders are obtained, which are dust-free and have a uniform grain size and structure. However, it is not possible using the method of the aforementioned type to produce detergents in powder form, the In order to obtain a dry washing powder, per compounds contain the good must be atomized hot. When atomizing hot solutions, suspensions or melts which, in addition to the other detergent ingredients, are also already perv erbindun.gen included, but are required as a result of the atomization process high temperature and the presence of water decomposes the per compounds, its active ingredient, active oxygen, is lost. For this Basically, one should also rely on the use of atomization products, to mix these with the per compounds afterwards, which in turn creates a mixture of substances obtained with different specific weights and the disadvantages associated therewith became. It was now. found that .man containing per compounds Laundry detergent in forin 'of a uniform powder of uniform grain size and Structure is obtained by means of spray drying in one operation, that hot solutions, suspensions or melts .the detergent components in the absence of the per compounds in atomizing devices in a gas stream atomized in the form of a hollow cone and at the same time in the upper: inner part of the hollow cone formed by the atomized particles, the respective for use arriving. Perveibindings in a powdery state sprayed in. At the. entry The finely atomized solution in the gas stream gets most of the water instantly evaporates. The atomized particles hit the while still semi-moist counter-blown solid particles of the per compounds together and enclose this like an insulating layer. As a result, the individual particles are the perversions against the action of a hot gas stream containing water vapor and the resulting caused decomposition largely protected. In this way you get a uniform. Powder, in which the individual particles of the Perverbindüngen are no longer next to The rest of the detergent components are stored in them or with them these are cemented. The new. Detergents and cleaning agents are therefore products with a uniform -specific weight that cannot separate.
Es. ist zwar bereits bekannt, daß man zum ununterbrochenen schnellen Trocknen oder Eindampfen auch heißer, fein zerstäubter Flüssigkeiten, die einzutrocknende Flüssigkeit im oberen Teil eines Turmes fein verteilt und in den so gebildeten Flüssigkeitsnebel fein verteilte feste Stoffe mittels Säug- oder Preßluft oder mittels mechanischer Mittel einführt. Dieses Verfahren ist jedoch im vorliegenden Falle für das Einsprühen von festen Perv erbindungen in Pulverform ungeeignet, da durch das unmittelbare Einsprühen der festen, z. B. Perboratteilchen in den heißen Flüssigkeitsnebel der Waschmittelhestandteile eine Zersetzung des Perborats stattfindet.It. it is already known that one can go for uninterrupted speed Drying or evaporation of hot, finely atomized liquids that are to be dried Liquid finely distributed in the upper part of a tower and into the liquid mist formed in this way finely divided solid substances by means of suction or compressed air or by means of mechanical Introduces means. However, this method is for spraying in the present case of solid perv compounds in powder form unsuitable because of the immediate Spraying the solid, z. B. Perborate particles in the hot liquid mist of the Detergent ingredients a decomposition of the perborate takes place.
Die neuen Waschmittel entsprechen in ihrer Zusammensetzung bekannten Waschmittelkompositionen, die beispielsweise Seife, Seifenersatzstoffe, Schaummittel, Perverbin-. dungen und andere Stoffe enthalten. Als Perverbindungen können Perborate, wie Natriumperborat, -Percarbonate, Perphosphate, Perpyrophosphate, Anlagerungsv erbindungen von Wasserstoffsuperoxyd an- feste Substanzen, z. B. Natrium- oder Kaliumcarbonat, Natrium-. oder Ammoniumsulfat, Metaborat, Natriumphosphat oder -acetat, verwendet werden.. Auch können Stabilisatoren in Verbindung mit den Perverbindungen zur Verbendung gelangen.The composition of the new detergents corresponds to familiar ones Detergent compositions containing, for example, soap, soap substitutes, foaming agents, Perverbin-. contain chemicals and other substances. Perborates, such as sodium perborate, percarbonates, perphosphates, perpyrophosphates, Anlagungsv bindings of hydrogen peroxide solid substances, z. B. sodium or potassium carbonate, Sodium-. or ammonium sulfate, metaborate, sodium phosphate or acetate is used .. Stabilizers can also be used in connection with the Perverbindungen reach.
Unter den Stoffen mit ausgesprochener Wasch- und Reinigungswirkung können außer Seife auch Gemische der Natriumsalze der Schwefelsäureester höherer Fettalkohole, Salze von durch höhere Fettsäurereste acylierten Methyltaurinen und andere Seifenersatzstoffe zur Verwendung gelangen.Among the fabrics with pronounced washing and cleaning properties In addition to soap, mixtures of the sodium salts of the higher sulfuric acid esters can also be used Fatty alcohols, salts of methyl taurines acylated by higher fatty acid residues and other soap substitutes are used.
Die Waschmittel der vorliegenden Erfindung können weiterhin auch alkalische Salze, wie Wasserglas; Natriummetasilicat, Borax, Soda, Phosphate, beispielsweise Alkaliorthophosphate, -metaphosphate und -pyrophosphate, und ferner Alkalisalze solcher organischer Aminocarbonsäuren, die für jedes basische Stickstoffatom mehr als eine Carboxyl-.gruppe besitzen, enthalten.The detergents of the present invention can furthermore also be alkaline Salts such as water glass; Sodium metasilicate, borax, soda, phosphates, for example Alkali orthophosphates, metaphosphates and pyrophosphates, and also alkali salts such organic aminocarboxylic acids, which are more for each basic nitrogen atom as a carboxyl group.
Die einzelnen Arbeitsbedingungen des Verfahrens, wie .die Temperatur des Gasstromes, die Behandlungsdauer, der Luftumlauf und der Druck, mit dem die zu zerstäubende heiße Lösung, Schmelze oder Suspension sowie die pulverförmigen Perverbindüngen zerstäubt werden, können je nach der gewünschten Beschaffenheit des Waschmittels ausgewählt werden. Je nach der gewünschten Beschaffenheit des Endproduktes kann man den Gasstrom, in welchem .die Zerstäubung vorgenommen wird, im Gleichstrom oder im Gegenstrom zu den zerstäubten Teilchen. führen; auch kann man mit einem heißen oder kalten Gasstrom arbeiten. Mit den Perverbindungen können in trockener Form -auch gleichzeitig andere Stoffe in festem Zustand mit den übrigen Waschmittelbestandteilen vermischt werden; beispielsweise Stabilisierungsmittel, Desinfektionsmittel, Fällmittel ü. dgl.The individual working conditions of the process, such as the temperature of the gas flow, the duration of the treatment, the air circulation and the pressure with which the Hot solution, melt or suspension to be atomized, as well as the powdery Perverbindüngen can be atomized, depending on the desired texture of the detergent can be selected. Depending on the desired properties of the end product the gas flow in which the atomization is carried out can be used in cocurrent or in countercurrent to the atomized particles. to lead; also you can with one hot or cold gas flow. With the per connections can be in drier Form - also other substances in solid state at the same time with the other detergent ingredients be mixed; for example stabilizers, disinfectants, precipitants ü. like

Vor der- Spitze n. befindet sich eine Einsatz o mit Spiralen nt. Wenn ilas zu zerstäubende Gut, das durch L' eingeführt wird, durch diese Düse hindurchgedrückt wird, wird es durch den Spiralengang fz in drehende Bewegung versetzt und verläßt den Aufsatz k in Hohlkegelform.In Fig. H is a device for the preparation of the new detergent containing per compounds. shown schematically in section - In this drawing, g denotes an atomization tower, which is conical-shaped at its lower part and has a device f for discharging the finished powder at the lower end; d is a device for the supply of hot veins of cold glass, for example air, nitrogen or carbonic acid, which can escape through e or through the annularly arranged air slots h. In the upper part of the atomizing tower is an atomizing nozzle a through which a solution, melt or suspension of the detergent constituents can be blown into the atomizing tube in the form of a hollow cone c; b is an atomizing nozzle for atomizing the powdery per compounds or mixtures thereof with other powdery additives. It is essential that the distance between the nozzles a and b is chosen so that the powdery pervex bonds always reach the upper inner part of the hollow cone c. It is not necessary that the nozzles a and b in the described arrangement are necessarily attached in the upper part of the Zarsfäubungstumes. They can also be located in the middle or at the lower end of the atomization tower, depending on whether the atomization inside the tower is from top to bottom or from bottom to top. The atomizing nozzles d and b are shown again in Figs. II and III. The atomizing nozzle a (see Fig. II) through which. the atomized material is brought into a hollow cone shape, consists essentially of a metallic hollow cone k, - in: the tip of which is the nozzle opening n . In front of the tip n. There is an insert o with spirals nt. When the material to be atomized, which is introduced through L ', is pressed through this nozzle, it is set in rotating motion by the spiral path fz and leaves the attachment k in the form of a hollow cone.
Die in Abb.III wiedergegebene Zerstäubungsdüse für die pulverförmigen Perverbindungen besteht aus einem konischen Zylinder r, in dem sich ein Kegel s befindet. Das zü zerstäubende Pulver tritt bei t in die Düsen ein und verläBt :die Düse durch den von .dem Kegel und dem konischen Zylinder gebildeten Kohlraum u..The atomizing nozzle shown in Fig. III for the powdery Per connections consists of a conical cylinder r, in which there is a cone s is located. The powder to be atomized enters the nozzles at t and leaves: the Nozzle through the cabbage space formed by the cone and the conical cylinder and
In Ausübung des neuen Verfahrens wird beispielsweise eine heiße, wässerige Lösung, die etwa ¢3 Gewichtsteile Seife, 17 Gewichtsteile Soda und 3 Gewichtsteile Wasserglas enthält, in der im vorstehenden beschriebenen Zerstäubungsvorrichtung durch die Düse a in Fbrm eines Hohlkegels in den Turm eingesprüht. Gleichzeitig wird festes, pulverförmiges Natriumperborat durch .die Düse b in den inneren Teil des Hohlkegels eingeblasen. Dabei wird die Zufuhrgeschwindigkeit des Natriumperborates derart bemessen, daB im Endprodukt ein Gehalt von etwa ioo% Natriumperborat vgrh:anden ist. Die aus der Düse b austretenden Perboratteilrchen gelangen in denjenigen Teil des Hohlkegels, in dem der Abstand der den Hohlkegel bildenden Teilchen noch sehr gering ist. Dadurch wird erreicht, daß die einzelnen Natriumperboratkörner von den: halbfeuchten, zerstäubten übrigen Waschmittelbestandteilen umschlossen werden. Auf diese Weise wird ein -einheitliches Pulver gewonnen, das im Gegenstrom zu dem aus d austretenden heißen Luftstrom durch den Turm herabrieselt und dabei vollkommen getrocknet wird. Die Zerstäubungstemperatur beträgt in der oberen Hälfte des Zerstäubungst.urmes etwa 14o0, in dem' unteren Teil des Zerstäubungsturmes nimmt die Temperatur beständig so ab, daß in dem untersten Ende des Turmes etwa eine Temperatur von 35°besteht. Gegebenenfalls kann auch noch Kaltluft zur weiteren Kühlung des zerstÄubten Materials an gesonderten Stellen zugeführt werden. Das fertige Waschmittel sammelt sich in dem unteren konischen Ende des Zerstäubungsturmes an und! wird durch die. Schleuse f aus dem Turm ausgetragen.In the practice of the new process, for example, a hot, watery Solution containing about ¢ 3 parts by weight of soap, 17 parts by weight of soda and 3 parts by weight Contains water glass in the atomizing device described above sprayed through the nozzle a in the shape of a hollow cone into the tower. Simultaneously solid, powdery sodium perborate is passed through nozzle b into the inner part blown into the hollow cone. The feed rate of the sodium perborate is thereby dimensioned in such a way that the end product has a content of about 100% sodium perborate is. The perborate particles emerging from nozzle b reach that part of the hollow cone, in which the distance between the particles forming the hollow cone is still very high is low. This ensures that the individual grains of sodium perborate from the: semi-moist, atomized remaining detergent ingredients are enclosed. on in this way a uniform powder is obtained, which flows in countercurrent to that from d emerging hot air stream trickles down through the tower and is completely is dried. The atomization temperature is in the upper half of the atomization tower about 14o0, in the lower part of the atomizing tower the temperature increases steadily so that there is a temperature of about 35 ° in the lowest end of the tower. If necessary, cold air can also be used for further cooling of the atomized material are fed in at separate locations. The finished detergent collects in the lower conical end of the atomization tower and! is through the. lock f discharged from the tower.
Im Rahmen des vorstehenden Verfahrens kann man an Stelle von Seife auch Fettalkoholsulfonate, Alkalisalze von durchi Oxydaxion von Paraffinen erhaltenen Fettsäuren, von durch höhere Fettsäurereste acylierten Mebhyltaurinen oder andere Seifenersatzstoffe verwenden.In the above procedure, you can use soap in place of also fatty alcohol sulfonates, alkali salts obtained by oxydaxion of paraffins Fatty acids, from mebhyltaurines acylated by higher fatty acid residues or others Use soap substitutes.
