Description

Verfahren zum Trocknen mit überhitztem Dampf. Es sind Trocknungsverfahreii bekannt, bei. denen der Raum mit dem Trockengut und die Heizvorrichtung in einen Kreislauf eitigeschaltet sind, welcher durch ein Luftrad aufrechterhalten wird. Auch ist es bekannt, bierbei Dampf zum Trocknen zu verwenden, der in der Heizvorrichtung überhitzt wird, während er sich am Trocken- gut wieder sättigt, wobei er sich um die aus dem Trockeng-ut entweichenden Dämpfe vermehrt; schließlich sind auch Trocknungsverfahren bekannt gewor,den, bei denen die zur VeDdampfungder Feuchtigkeit (des Trockengutes notwendige Wärrnemenge !durch eine Verdichterinaschine geliefert wird.Method of drying with superheated steam. There are drying processes known at. which the room with the dry goods and the heating device in one Circuit are switched on, which is maintained by an air wheel. It is also known to use steam for drying in the heating device is overheated while he is saturated again on the dry material, whereby he turns the vapors escaping from the dry goods are increased; Finally, there are also drying processes became known, those in which the evaporation of moisture (of the dry material necessary amount of heat! is supplied by a compressor machine.

D Von diesem letzteren Verfahren unterscheid#et sich der Erfindungsgegenstand dadurch, daß das Verfahren, die Verdampfungswärme der Feuchtigkeit des Trockengutes zu ver-,lichten, auf ein Trockenverfahren angewandt wird, bei dem Dampf im Kreislauf an einer Heizvorrichtung überhitzt wird, während er sichbeim Durchströmen des Trockengutes wieder sättigt, indem auf der Abflußseitt des Trockenraumes so viel Dampf abgezapft wird, als sich durch die verdampfte Feuchtigkeit neu gebildet hat, und daßdieser Dampf auf höheren Druck aus dem Ver-dichter abgeführt und mit !dementsprechend erhöhtein Wärmegrad (dem in den Kreislauf eingeschalteten Heizkörper zugeführt wird, indem er sich niederschlägt, dadurch seine Wärme an den Kreislaufdampf abgibt und ihn Überhitzt. D From this latter method distinguishable #, the subject invention et characterized in that the method of comparison, the heat of evaporation of the moisture of the dry, clear, is applied to a dry process, is superheated in a heater in the steam in the circulation while sichbeim flowing of the dry material is saturated again by drawing off as much steam on the discharge side of the drying room as has been newly formed by the evaporated moisture, and that this steam is discharged from the compressor at a higher pressure and with a correspondingly increased degree of heat (that in the circuit switched on radiator is supplied by it precipitates, thereby giving off its heat to the circulating steam and overheating it.

Eine Vorrichtung für die Verwirklichung des Verfahrens stellt die Zeichnung schernatisch dar. Der Kreislauf besteht aus den Teilen a, b, c, d, e, f, g; in diesen hält der Lüfter d den Kreislauf des Dampfes aufrecht, der durch die Leitung e in den Heizraum f ,gelangt, aus idem er überhitzt durch die Leitu#ng g zum Trockenraum a strömt, um dann, gesättigt und vermehrt um den Dampf, der sich aus der Feuchtigkeit des Trockengutes gebildet hat, durch b auszutreten und durch die Leitung c zum Lüfter d zurück7jukehren. Dabei wird jedoch beim Übertritt des Dampfes aus der Leitung b in die Leitung c ein Teil des Dampfes, und zwar etwa so viel, wie sich aus der Feuchtigkeit des Trockenggutes neu gebildet hat, -durch die Leitungh zu einem zweiten Verdichter i geführt, wo er auf höheren Wärmegrad gebracht wird, um dann ,durch die Leitung k dem Heizkörper 1 des Heizrarumes f zugeführt zu werden, in dem er sich niederschlägt, wobei aucher seineWärme an den im Kreislauf strömenden Dampf abgibt und diesen Jaidurch aufs neue zum Trocknen bef äiiigt.A device for the implementation of the method is shown in the drawing schematically. The circuit consists of the parts a, b, c, d, e, f, g; In this, the fan d maintains the circulation of the steam, which passes through the line e into the heating room f , from which it flows overheated through the line g to the drying room a, and then, saturated and increased by the steam, the has formed from the moisture in the dry material, exits through b and returns through line c to fan d. In this case, however, when the steam passes from line b into line c, part of the steam, namely about as much as has been newly formed from the moisture in the dry material, -through the lineh to a second compressor i, where it is brought to a higher degree of heat, in order then to be fed through the line k to the heating element 1 of the heating room f , in which it is deposited, whereby it also gives off its heat to the steam flowing in the circuit and thereby enables this to dry again.

In dem Kreislauf a, b, c, d, e, f, g kann je nach dein Wärmegrajd, mit idem getrocknet werden soll, eine Spannung, die höher, gleich oder niedriger als die Außenluft ist, herrsch,en. An Stelle def Umwälzvorrichtungd kann,der Kreislauf auch allein durch den Gewichtsunterschied zwischen Überhitztem und gesättigtem Dampf aufrechterhalten werden.In the circuit a, b, c, d, e, f, g , depending on the degree of heat that is to be used for drying, a voltage that is higher, equal to or lower than the outside air can prevail. Instead of the circulation device, the cycle can also be maintained simply by the difference in weight between superheated and saturated steam.
