Definitions

• the invention relates to a heating method, in particular for apartments, using a powder or granular mixture consisting of a plastic and a stabilizer, which is swirled with air in a dry mixer, the outer wall of the mixer being used to dissipate heat with water is washed around, which circulates in a heating circuit, and a device for carrying out this method, consisting of a double-walled container with a swirling device arranged in the interior of the container, water being carried in the intermediate space of the double wall as part of a heating circuit.
• the process known from DE-A-35 00 821 is based on the fact that PVC granulate or powder is heated during mixing and can be removed from the cooling jacket of a mixer.
• a tin-containing substance to the PVC-containing material and to swirl this mixture for several days to several weeks, and this in the process dissipate heat generated due to the composition.
• a higher or lower heat can be generated.
• the wing mixer arranged in the mixing container and extending over the entire interior of the mixing container swirls the starting material in the entire container space, so that the heat generated is evenly emitted and removed from the entire container wall surface designed as a cooling jacket .
• the cooling jacket surface is thus larger overall; the efficiency is thus improved.
• An octyl-tin mercaptide is preferably used as the mercaptide.
• the swirling is carried out in a lying drum container, in which a wing mixer rotates relative to the drum inner container wall.
• a drum container has the advantage that no niches with only slight turbulence can arise and that the mixing can be carried out homogeneously over the entire cross section.
• the vane mixer is preferably operated at a speed of 1,450 to 2,900 rpm. operated.
• the process according to the invention can be operated without exhaust gas, further savings can also be achieved by, for example, using PVC-containing material from waste and old material in the form of used bottles or the like.
• the heat of the swirled material is expediently limited to a level not exceeding 160 ° C. with the dissipation of heat. However, one is preferred at about Limiting temperature between 150 ° C and 160 ° C. In this way, heat losses can be avoided.
• the cylinder space for swirling should be selected so that the ratio of the diameter to the length is approximately 5: 8 to approximately 5:10 for a filling which occupies approximately 40% to 60% of the height.
• the selection of the stabilizer also makes it possible to use plastics other than PVC exclusively as starting material, so that the process also enables the recycling of other types of plastics. It has been shown surprisingly that only with the use of an octyl-tin mercaptide can other types of plastics be used, e.g. Polyvinyl acetates, polypropylenes, where it is expediently advantageous if the different types of plastics e.g. a proportion of up to 80% by weight is added. It is particularly advantageous to use the plastic granulate PSK 100, which has a high abrasion resistance, low wear and no energy depletion, so that it can be used as a long-term material.
• the preferably cylindrical container is arranged horizontally and has a rotation around a horizontal axis, extending over the entire length of the container and occupying the entire interior of the container Has wing mixer. In this way, practically the entire interior of the container can be used for swirling and not only 90% as in the standing container according to DE-A-35 00 821.
• the wing mixer is preferably attached to a horizontally arranged, motor-driven shaft, from which a plurality of arms projecting radially from the shaft protrude with end-side blade plates. These blade plates are at 30 ° or 6 ⁇ 2 with respect to the arms. + / + / - 15 ° inclined. This tendency causes a scoop-like conveying and mixing of the amount of content.
• each of the blade plates extends essentially over the entire interior length of the container and is held over a plurality of preferably three arms arranged one behind the other and projecting radially from the shaft.
• the blade plate is stabilized as much as possible with maximized efficiency over the entire length of the container interior. It has proven useful if at least three, preferably four blade plates are provided, each at the same angular distance of 120 ° or 90 °.

• the heat generator shown in Fig. 1 consists of a double-walled cylinder container 10, which has an intermediate space between its outer jacket 11 and its inner jacket 12, in the respective coils 13 for service and / or heating water are arranged.
• the heating water inlet is denoted by 14 and the outlet by 15, while the service water inlet has the reference number 16 and the service water outlet has the reference number 17.
• the outer cylinder jacket 11 suitably has a length 1 of 60 cm, while the inner jacket has a length 10 cm shorter. Both containers are made of copper sheet.
• the container 10 extends through in the region of its longitudinal axis by a shaft 18 which is connected on one side to a motor (not shown) and is supported in bearing bushes 19.
• the shaft 18 serves as a carrier for a wing mixer 20 which extends essentially over the entire length of the interior.
• This wing mixer 20 has arms 21 which are arranged on the shaft and which are arranged in a crosswise manner (FIG. 3).
• Each of these arms carries a blade plate 22 at its outer end, i.e. in the case of FIG. 3 four blade plates, which extend over the entire length of the interior and each of which is held by three arms 21 each.
• the arm has a thickness d of approximately 0.5 cm. The distances a are approx. 20 cm.
• the interior of the container 23 is half-mixed with a mixture of a plastic powder, for example a PVC powder or granulate, with a stabilizer made of octyl-tin mercaptide. fills. Due to the horizontally arranged container 10, a high degree of efficiency and a high energy gain are obtained. Due to the swirling of the filling when the shaft 18 rotates, the plastic molecules become charged; the heat generated by the static charge is released to the inner jacket 12, from where it is conducted to the water in the tubes 13. 100% utilization of the PVC granulate in heat is achieved.

• the use of the stabilizer mentioned does not exhaust the PVC granulate and avoids degradation reactions or agglomerations of the PVC parts, in particular due to the mercaptide used, which acts as a protective covering around the particles of the PVC granules and thus stabilizes the PVC granules for a longer service life.
• the mercaptide used acts as a protective covering around the particles of the PVC granules and thus stabilizes the PVC granules for a longer service life.
• a powder or granulate made from another suitable plastic can also be used, such as also polymers.
• the wall of the container 10 is made of plastic, expediently from PVC or another heat-conducting material, such as sheet steel, which is coated on the inside wall with a plastic, expediently with PVC.
• the heat generation is significantly improved by the interaction of the plastic parts of the mixture used with the container wall consisting of a plastic.
• Surprising results are achieved when using a container Wall obtained from a plastic if a mercaptide, in particular an octyl-tin mercaptide, is incorporated into the plastic and is released over a longer period of time to the mixture present in the container during the swirling process.
• the mixing of the powdery or granular mixture with air in the container interior 23 can be improved further by selecting the circumference of the blade plates 22 such that an intermediate space 29 is formed between the free edges of the blade plates 22 and the inner wall of the container is so that particles of the mixture thrown off the scoop plates 22 bounce off the inner wall of the container and are thrown towards the center of the interior of the container, where they collide with the other particles of the mixture.
• This bouncing back of the particles from the inner wall of the container is further supported by lining the inner wall of the container with a resiliently elastic material, such as e.g. with rubber, a rubber-like material or a plastic, e.g. Silicone rubber.
