The subject of the main patent is a method and device for glazing bitumen, Das The essence of the process consists in the fact that one is in a reactor which is connected to an ascending zone subsequent downward leading zone or several such Contains zone pairs connected in series, from preheated Source material with one or more upward «zones inform of the source material finely dividing and sweeping rays blown in, At the same time, air foam also acts as a carrier gas forms, this foam during its transition in the downward leading zone or zones at least partially breaks and the blown bitumen from the last or that downward zone in which there is the has already acquired the desired properties. In the reactor, which is still the subject of the main patent, and which has one outer and one The inner coat has and the outer coat ends in such a widened part, which is covered with foam bristle batts and gas discharge nozzle is provided, the bitumen and the air introducing element from one such a head exist in which the bitumen and the air are introduced through coaxial pipes in such a way that di>: perforated mouth dor inner air duct in one Constriction of the outer bitumen pipe protrudes;

Effectiveness of the procedure, also on the expansion of the blown product types

The process according to the main patent can be carried out with a Starting material in the blower system described for implementation in a small and medium-sized company Help of the technical information given in the example in the description Characteristic values can be realized without further ado. For the purpose of blowing one made up of different starting materials Mixture v / crden the starting material ion stirred in separate mixing containers before blowing, for The cross-section and content of the reactor, as well as those introduced during the unit of time, must be achieved to a large extent Air volume can be increased accordingly. In order to meet these increased demands, the reactor is therefore ideal the main patent, only with additional investment and operating costs suitable »To achieve an extremely large output Several roactors have to be installed, whereas mixing tanks have to be installed for the joint blowing of different raw materials which increases both the investment costs and the operating costs

The increase in the amount of air can be achieved by the invention described in the main patent in such a way that the already high linear speed in the blower head described in the main patent is further increased.However , it seems more advantageous, in addition to the increase in the cross-section of the reactor, also several blower heads to be installed appropriately distributed. With such a design, the desired effect, that is to say, the blown-out situation can be achieved with the help of the characteristic values described in the main patent, but this design, which shows several blown heads, requires a separate distribution system.

room arranged distribution system is provided found that, especially when using a starting material of greater viscosity or softening point, the judgment system also operates against smaller ones Cooling - initially against cold weather - is sensitive, while in the case of larger cooling the bitumen introduced can even freeze. This is due to the inevitably used smaller pipe cross section of the distribution system ago, in don the flow conditions more unfavorable while The Wämeleitf laugh.

The essence of the further development of the patented invention consists in that the pipe, which feeds the bitumen or other raw material, into the reaction chamber designed in the lower part of the reactor but completely closed space opens and the air inlet pipes - penetrating this space - into the Bituiienvcdcensionstutzen adjoining the closed room arranged concentrically and tbrdrj <ms such are slides into the reaction space, as i: .i main patent be »-

- It was also found that the interior design of the upper, enlarged head part of the reactor to the extent that "unavoidably" occurs during the blow-off Coking in the gas room, on the character of the coke and exerts a significant effect on the quality of the blown bitumen

A further purpose of the invention is the possible elimination the effects occurring in the head part of the reactor and thereby the · reduction of coking and the reduction to a minimum of the number of cleaning periods · these The second purpose is achieved in that the foam breaker plates are attached at different heights in the enlarged head part, partially perforated - and indeed in such a way that the Perforations on top of each other or in relation to each other vcr-setä are-arranged and as well as on these as well. over which the liquid level steam is blown in ..

Of the examples demonstrating the use of the invention, Example 1 illustrates the effect of a new arrangement and design of the Schauribrecherplatten and the Wassexdanpfzuführ while example 3 offers a further processing option, Example 4, on the other hand, demonstrates the processing possibility of two different blown starting materials.

The technical progress of the blower head described in the additional patent in comparison with the blower head known from the main patent is proven by Example 1. In this case, the lower part of the reactor is designed according to the additional patent »its head part, on the other hand, is designed according to the main patent Room 5 of the lower reactor part 3 »2!

The Bitunen obtained in this way had a softening point of 85 ⁰ O, a penetration JO to 32 at 25 ⁰ O, and a clay temperature of -12 ⁰ C was enjoyed as the Fraass breaking point continuous operation kept. Per 24 hours were introduced 28 tons Bitunen and practically as much product nit a softening point of 85 ⁰ G, a penetration 30 to 32 at 25 ⁰ G, and a Iraäss refractive point of -12 ⁰ · G obtained

The results of the multi-level arrangement of the ßchauD— breaker plate system and the water vapor pipeline gonäss the additional patent in comparison with the design of the head part of the reactor described in the main patent are the following example underpinned

EXAMPLE 2 The material described in Example 1 was blown under the operating conditions set out there, but with the use of the reactor head part disclosed in the additional patent, the following properties of the product produced during several weeks of operation being enjoyed: Softening point 85 ⁰ Cf Penc- Trntion 35 at 25 ⁰ O, Fraass breaking point -14 ⁰ O, During cusse's operation, the coke formation on the reactor wall delimiting the gas chamber and on the surface of the Schaunbrecherplattec-n was only about 10 % in comparison with the ones that occurred in a design of the head part according to the main patent

Counterexample to Example 2: As a counterexample, reference was made to the information in Example 1, where only the lower part of the reactor contained the additional patent, while the main patent was designed accordingly

In order to expand the range of blown products and to increase their effectiveness, example 3 is given.

The starting material was blown for 3 hours in one experiment and 6 hours in another, and the end product obtained in this way had a softening point of 92 ^° C. "KS" or 128 ^° C. "KS".

Counterexample to Example 3 * Basal yellow starting material was blown in a conventional bituminous blower with a ring-shaped air distributor. I> he softening point has increased in 3 hours only to 74 ⁰ O in 6 hours to 94 ⁰ O,

-. Regarding the use of the starting material consisting of several components, we refer to example 4 «

If an extract from refining with a solvent of a heavy oil distillate or residual oil is mixed in an amount of 10 to 30 % with a propane-containing bitumen of Ronaskino origin, a road construction bit UB-65 or ΌΒ-75 that fully complies with the regulations can be created by blowing this modified starting material "Through this ideclmology, used all over the world for the most varied of starting materials, both components that are difficult to use - the propane-containing bitunone and the refined extract - have been transformed into a valuable product and useful for satisfying existing requirements.

Opposite example to Example 4: By blowing the distillation residue of a petroleum of Ronaskino origin, and even further by blowing the bitunene obtained with propane, which was not dehased with propane, the penetration, ductility and breaking point regulations of the road sundrying point can not be met if the higher standards of road construction are not met for example, the Fraass Brechungspmikt of propanhaXtigen Bitunens nit a softening point of 55 bit 60 ⁰ C
