Abstract

The invention relates to a method and an apparatus for drying pourable material in a drying silo (1) by means of an air flow. The used air flow (5) that is discharged from the drying silo (1) or the returning air is dried in a drying cell (6) containing a drying agent or adsorbent and is fed to the pourable material as a dry air flow (3). If necessary, the adsorbent is regenerated in the drying cell (6). The used air flow (5) is fed to a supply duct that is disposed in the drying cell (6) and is connected to the adsorbent, is deflected in the drying cell (6), is conducted across the adsorbent, is then deflected once again as a dry air flow (3), is withdrawn in a discharge duct against the direction of flow in the supply duct, and is fed to the drying silo (1). The drying cell (6) that is designed as a wheel-type drier is rotated in stages or continuously. The drying cell (6) is designed as a drum comprising at least three concentric, axially extending zones (20, 21, 22). The adsorbent is located in the central zone (20), while the two other, external and internal zones (21, 22) are designed as ducts for the used air flow (5) or the dry air flow (3). The ducts are connected to the zone (20) containing the adsorbent in order to allow air to penetrate therebetween.

Description

200916713 VI. Description of the Invention: [Technical Field of the Invention] The present invention is a method for drying goods (especially solid objects such as particles, powders, grains, foils, chips, plastic particles, etc.) by using a gas stream in a dry silo And the structure; mainly the waste stream discharged from the dry silo or shouting in a drying chamber containing a desiccant/adsorbent, and if necessary, regenerating the adsorbent as a dry stream supply. ',', [previous technology]

There are many methods and constructions used to dry goods, such as DE 3625 〇 13 A1, a method and apparatus for drying plastic pellets in a drying funnel using dry air. In the 4 creation towel, the exhaust gas mainly discharged from the funnel 35 is dried in a dryer containing an adsorbent, and the goods are returned as dry air. As DE 197 still views, it is disclosed that the air of the cargo is dried and w... the structure contains at least a drying cylinder, a lower air heat thief, a lower dry cargo compartment and a lower cooling equipment. If the 118762 is deleted, the square pole that regenerates the compressed air of the water-containing gas is to be heated to the air in the atmosphere, sent to the drying cylinder to be regenerated, cooled again by the same θ, and then dried. Some airflow will leak out. ^ EPG712656B1 'Exposure is a method of drying wet air, and such as Ερ7 shed 56, revealing a method and construction for regenerating a moisture-containing adsorbent. ,skin. As disclosed in DE 2025 205 A, the structure and structure of the selectively adsorbed molecules in several chambers have the following common deficiencies in the above-mentioned various creations - regeneration and money require a lot of energy, and the constructed equipment A very high amount of money is spent on construction. The creation, the lack of description, the development of the case of this case and the construction of this case, which saves energy, can also effectively reduce costs. SUMMARY OF THE INVENTION, 3 200916713 The method is a method for drying goods by using airflow in a dry silo and a structure. The operation of the drying chamber is divided into at least three 'axial extensions in a cylindrical shape. The field in which the adsorbent is arranged in ___ = inside __ as a hearing button or wire (four) vocabulary; the pipe has a field of adsorbent connected as an air passage. _The above set of transfer routes 忐Achieve even if the steps in the process are different, but only use a $ can also reduce the total investment and operating costs. The use of life can be said, and the invention has another -_, that is, not only "has the sulphur's public energy, but also effectively reduces the cost. _ tInvented design also meets the needs of different products and technical fields. The replacement of different material shell members can meet the needs of different industries. ° Compared with the = dry = room, the bottom of the drying chamber has a bottom, the other end has a top, and the other uses a (10) structure. The structure of the creation is simple and the price is also It is cheaper. One far = the upper part of the upper part is designed with a joint cover, and only one connection is needed in the execution technology. The cover 'has better industrial utilization than the conventional structure.
