at the same time stoffsuspensionen, whereby the medium is degassed it is interfered, and with the promotion and degassing a fluid into the medium. Further the invention concerns a device for the execution of the procedure. Procedures and/or devices for separating from gaseous components are well-known e.g. from the RK 391628 or the RK 396205. To degas and thus used for a following pump make promotable these devices around fibrous material suspensions in the central consistency range. A such device is in most cases inserted with the supply to a Reaktionsbehälter. Here it is to be interfered additionally necessarily necessary chemicals into the fibrous material suspension, at present takes place this in special mixers e.g. after the RK 403063 in the supply piping. Further are mixers from the WHERE 87/00448 and US 5.813.758 well-known, whereby in the outside range feed parts for e.g. bleaching media are intended here. These devices the disadvantage that the mixture only takes place insufficiently is, in particular with the WHERE 87/00448 the suspension almost without mixture again delivered and continued to promote. A pump describes the WHERE 87t00448, with which apart from a degassing also a supply is intended by chemicals in the spiral. Thus only a short time for a possible mixture is granted. Since the chemicals are promoted together with the suspension, essentially also no relative velocities exist among themselves and the danger arises that it comes to local over reactions. US 5.813.758 shows a fluidization mixer, with which likewise an addition is from the outside intended by chemicals. Since an exhaust is arranged only in the center here, the danger exists that with gaseous media still reactive portions are mLtabgesaugt. Will the chemicals together with the suspension ge2s promotes also here and it to exist essentially also no relative velocities among themselves. Thus the danger arises also here that it comes to local over reactions. Since 'also no distribution is made by the passage area, an even reaction or heating with these means is not attainable. If steam is to be interfered for the heating up of the medium, this takes place often through at the tubing extent arranged nozzles, so that an allocation of the total quantity which can be proportioned takes place on several (many) dosing places. The disadvantage all these procedures and/or arrangements consists of it that steam causes, locally overheatings in the dosing places, what e.g. with fibrous material suspensions to damage to the fibers would lead. • a goal of the invention is it now a fluid into a liquid medium - for example fibrous material suspension, (cellulose suspension for example mitlelkonsistente), to interfere evenly. The invention is characterized by the fact from there that the fluid which can be interfered is brought in the range of distribution mechanism, for example a distribution star, arranged by the rotor for promotion planned of the pump of separated rotor and at this rotor, directly into the medium, e.g. fibrous material suspension, and over the passage area distributed evenly. So it cannot come during steam interference to no local overheating and when e.g. interference of bleaching chemicals also to local over bleaching. The invention is particularly favourable, if into the medium, for example fibrous material suspension, steam is interfered and thus the medium, for example to fibrous material suspension to a higher temperature, is warmed up for example up to 180 °C. During suitable execution of the feeding equipment added steam is already condensed before entering the spiral housing of the pump in the medium, so that a troublefree enterprise of the pump is ensured. Similar is valid, if into the medium, for example fibrous material suspension, liquid chemicals or solutions like e.g. water, peroxide, caustic solutions, acids, additives, catalysts or auxiliary materials, are interfered. So also the pH value necessary for a reaction can favorably and evenly be stopped apart from a particularly favorable supply by e.g. bleaching chemicals. It proved particularly favorably, if steam and/or gas and-blaze liquid are together interfered. The invention is characterized further by the fact that the fluid with a high relative velocity, which can be interfered, is interfered to the flowing medium into the medium e.g. fibrous material suspensions. The invention concerns also a device for promoting liquid media, for example fibrous material suspensions, whereby the medium is degassed. This is characterized according to invention by it that for degassing by the rotor for promotion planned of the pump separate rotor is intended with openings and at this rotor a distribution mechanism, for example a distribution star, by which fluids which can be added directly into the liquid medium is brought and over the passage area distributed evenly. It is particularly favorable, if separated the arranged rotor exhibits a hollow shaft for removal the gases bring along with the medium, whereby the rotor can exhibit a further hollow shaft for the supply of the fluid which can be interfered. Alternatively also the rotor can exhibit a hollow shaft for the supply of the fluid which can be interfered and take place the removal of the bring along gas via a separate pipe. For an optimal organization several distribution mechanisms can be intended by different media to the supply. For a particularly favorable interference that a further rotor is arranged, the one hollow shaft for the supply of a fluid, in particular steam can be intended, exhibits. A particularly compact solution consists of the fact that the hollow shaft is led to the supply of the fluid by the wave of the pump. The invention is characterized further by the fact that at the same time with the promotion, degassing and heating up of a liquid medium, a gas, preferably reaction gas e.g. Oxygen, ozone or chlorine, in addition, steam into the medium are interfered. This takes place for example via at least one, preferably several, at the spiral housing of the pump arranged dosing equipment, e.g. distribution nozzles, so that an allocation of the total quantity which can be proportioned takes place on several dosing places. The invention is exemplarily described now on the basis the designs, whereby Fig. 1 a device for the separation of gases in accordance with the state of the art, Fig. 2 a variant of the invention, Fig. 3 a further variant of the invention, Fig. 4 a variant of the invention with several feed points, Fig. 5 a variant of the invention with rotor directly before the opening of the pump, Fig. 6 a variant with hollow shaft by the pump and Fig. 7 additional dosing places for fluids of each kind at the spiral housing of the pump represents. Fig. 1 shows a device for degassing a centralconsistent fibrous material suspension, with a consistency of approx. 8 - 15%, before the inlet to a pump 1. the device 2 are attached at the ground of a container 3 and hand a short piece into this container inside. By the rotation of the rotor 4 air in the center 5, contained in the fibrous material suspension, is collected and exhausted over a line 6 outward. The degassed suspension is further-promoted by the pump 1, whereby degassing is thingable for problem-free promotion unab4. Fig. a similar variant shows 2 in accordance with the invention. Over a double hollow shaft with degassing by the internal hollow shaft 6 of the rotor 4 of the medium supplied by line 3, over the outside hollow shaft 7 steam for warming the medium up are fed at the same time. Steam thereby over, at least one, to the rotor fastened Verteilstem with high relative velocity in relation to the medium directly into the medium fed. Further the possibility is to be brought in represented also additional liquids over nozzles 8 in the range of the relative velocity produced by the rotor 4. This takes place directly after the heating via steam, so that the necessary reaction temperature prevails already here and an even reaction is ensured. By those promotion of the suspension by means of a pump 1 the mixture of the suspension with the supplied chemicals is improved again and the process printing necessary for the promotion and reaction is produced. An alternative arrangement of the invention is in Fig. 3 represented. Here with the medium bring along gases of the rotor 4 are exhausted over a separate line 6 ' from the center and supplied to that the medium erw irmende steam by a hollow shaft 7 '. The possibility of the additional supply is intended by liquids also here. In place of steam naturally also another gas or also a liquid can by the hollow shaft 7 ' (and/or 7 in Fig. 2) directly into the range of high relative velocity of the rotor 4 to be supplied. Fig. a variant shows 4, with which the rotor exhibits 4 additional distribution mechanisms 9 and which is e.g. fed steam by separate mechanisms, nozzles 10 directly into the range of the high relative velocity produced by the rotor 4 and distributed evenly there. In Fig. a variant is represented 5, with which steam is supplied by a separate hollow shaft 11 with a rotor 12 directly before the intake of the pump 1 and thus a still even distribution is obtained. With suitable choice of the distance of the rotor 12 with the exhaust nozzles steam is already condensed with the entering the pump, so that also here no danger of Gasbzw. Arises to steam impacts. The variant of Fig. corresponds to 6 to the execution of Fig. 5, whereby however the Dampf-zufuhr takes place here via a hollow shaft 1 1 ', which is passed through the pump. In this case also the rotor 12 with the pump wave can corotate and needs no separate drive. With the variant of Fig. to 7 corresponds the range rotor to pumps eneintritt one of the variants of Fig. 2 to 6 or a combination or a variation from these. Dosing places 13 are additional attached by those the medium all kinds by fluids to be added can to suitable places of the spiral housing of the pump 1. The invention essentially covers several sections. In the first section by a rotor the medium is degassed. The rotor produces additionally a form before the pump promoting the medium. In the range between this rotor and the pump (the second section) devices are installed those it permit steam for warming up the medium and/or liquids the medium finely distributed to add. The third section consists of that, promoting the medium, pump. To the supply of further fluids of all kinds attached in practice several, its at the spiral housing of the pump at least dosing places can do one, (fourth section of the pumping system).
