Definitions
- the invention relates to a drying system for drying free-flowing Products, in particular for drying grain according to the generic term of claim 1.
- the material to be dried is usually introduced from above into a drying tower, in which it is in the course of the run is dried by means of warm air.
- a drying tower in which it is in the course of the run is dried by means of warm air.
- drying modules consist essentially of horizontal, inverted V-shaped, ridge sheets exist which are spaced parallel next to each other and in several layers one above the other are arranged so that in the next lower position the ridge in each case Space between the ridges of the layer above is.
- the ridge sheets are fastened in end sheets at their front ends.
- the Dried material runs on the top of a ridge sheet, is laterally there derived below and falls on the ridge sheet of the next or the next underlying layer of ridge sheets.
- the flow of warm air With a sensible arrangement, ridge sheets result in an even distribution of warm air over the module cross section.
- Additional towers are therefore provided on two sides of the drying tower the warm air led through the drying tower in and out.
- the tower for supplying the warm air is used as a supply air hood and the tower for discharge referred to the air as an exhaust hood.
- the temperature gradient between The supply air side and exhaust air side depend on the intended drying capacity, and also the degree of heat loss through the skin of the Drying plant, which in turn from the airtightness as well as the insulation or the heat transfer coefficient of this outer skin depends.
- the question, whether and to what extent the outer skin must be isolated depends on not exclusively economically on the costs of the energy supplier, but from the demand for an even temperature distribution and thus also of an even drying process over the entire Cross section of the drying column.
- the drying tower consists of one another stacked drying modules.
- the supply air and extract air hoods consist of many interconnected sheet metal parts with stiffening elements, which insulated on the outside and covered with thin facade sheets.
- the stacked drying modules and their supply and exhaust hoods are attached to supports, usually made of steel profiles, however these steel supports are not self-supporting scaffolding, but result only in combination with the drying modules and the outer sheet stable whole.
- supports usually made of steel profiles, however these steel supports are not self-supporting scaffolding, but result only in combination with the drying modules and the outer sheet stable whole.
- a static calculation of this design and first their dynamic loads were never possible, but such Drying systems were always designed based on experience.
- drying tower which consists of stacked one on top of the other
- drying modules which in turn are four each in pairs have opposite side walls.
- facade sheets for thermal insulation and / or additional elements such as Dust Collectors to be placed in the upper area of the drying tower
- the drying modules are stabilized by struts and supports to the grown To meet stability requirements.
- At least the drying tower is composed of a framework of longitudinal and Cross struts formed that self-supporting even without the use of drying modules and stable, and the drying system on the outside with panels disguised, which, if desired, can have an insulation layer.
- Preferably sandwich panels with three layers are used are made of a thin inner and outer wall, mostly made of metal, and an inner insulating material.
- Corresponding connection or holding means are provided on the scaffold
- the supply air and exhaust air hood preferably also have a self-supporting, stable scaffolding and an outer cladding.
- the continuous panel planking represents a fire protection barrier, which enables the drying system to be empty of flammable objects, to be arranged on buildings, for example, when using analog sandwich panels with foamed insulating material, which has a low flash point has.
- the Sandwich panels Because of the multilayer structure of the panels and the flat, mostly glued, Have connection between the individual layers of the panels the Sandwich panels have high inherent rigidity, and increase the resilience of the Supporting structure in addition, if the panels, for example, by means of self-tapping screws can be attached to the frame from the outside.
- the inner wall of the sandwich panels preferably does not consist of Sheet steel, but in particular made of aluminum or stainless steel, especially to to prevent corrosion of the exhaust hood.
- the outer wall can be made galvanized steel sheet or also aluminum sheet or stainless steel.
- the supporting structure of the drying plant is preferably completely with the Sandwich panels clad, which preferably run horizontally across the entire length or width of the drying system are arranged so that only the Corners butt edges are present.
- the abutting edges themselves can e.g. B. with Corner profiles made of aluminum are covered.
- a particularly simple and quick assembly of the panels can be achieved with a tongue and groove connection can be achieved by the one longitudinal edge of the panel groove-like recess in the longitudinal direction and the opposite Edge of a shape similar to the groove, also continuous in the longitudinal direction Has extension.
- the tongue and groove connection can also be made of metal, in particular metal profile, which are preferably from the outer wall is thermally separated.
- Sandwich elements have very good thermal insulation and high airtightness. The The drying system can therefore be operated with very little energy and thus enables economical drying.
- a further improvement in efficiency can be achieved if one part the warm air after passing through the drying tower the warm air circuit is returned.
- part of the warm air preferably about 30%, returned from the exhaust hood to the supply hood.
- the return of the Warm air is preferably drawn through the lower part of the drying tower.
- the drying tower includes cooling modules in addition to the drying modules are arranged at the lower module level.
- the cooling modules are cooled with cold air, which heats up as it passes through the cooling module.
- the heated cooling air can in turn be fed to the hot air circuit, thus the efficiency of the Increase plant.
- the cooling air is preferably from the side of the exhaust hood in the direction of Supply air hood, i.e. in the opposite direction to the warm air, is directed and is added to the supply air after it has warmed up.
- With lockable Openings in the supply air hood can match the size of the cooling zone can be adapted to different products.
- the dedusting system can in particular be in a separate room in the upper Area of the drying plant can be arranged if the load capacity of the Scaffolding is designed accordingly.
- This also has the advantage that none additional external dedusting room must be provided and in particular no additional floor space is required for the dedusting system and because of the height of the positioning and the panel cladding already a certain Noise protection as well as fire protection is achieved. Even if all other electrical Motors preferably in a separate, dust-free air flow Space in the lower part of the dryer, this has the advantage that here too there is noise and fire protection through the cladding, as well as all applicable Ex regulations can be observed.
- the other and faster method is to use pre-assembled units, for example units to be stacked on top of each other, put together, each from the supporting structure, the arranged therein Modules and any other elements they contain, such as pipes, Air ducts etc. exist.
- pre-assembled units for example units to be stacked on top of each other, put together, each from the supporting structure, the arranged therein Modules and any other elements they contain, such as pipes, Air ducts etc. exist.
- These pre-assembled units can, for example placed on top of one another by means of a crane and screwed together and in this way the Drying system can be set up very quickly.
- the paneling with sandwich panels is preferably carried out only after complete construction of the drying system as the last step.
- the drying plant 1 shown in Fig. 1 comprises three towers 2, 3, 4, of which the actual drying tower 3 is arranged in the middle. At the top of the Drying tower 3 is the material to be dried via a feed device 5 in the Drying tower introduced.
- the drying system further comprises an inlet hood 2 and an exhaust hood 4, the are arranged on opposite sides of the drying tower 3.
- the hoods 2, 4 are used for supplying and removing warm air through drying modules in the intermediate drying tower 3 is passed.
- the one with moisture saturated exhaust air is finally largely through an air outlet 6th blown out.
- a smaller part of the exhaust air is in the lower area of the drying system 1 from the Exhaust hood 4 returned to the intake hood 2 and in an air circuit recycled.
- the drying tower 3 also includes a Cooling module that serves to cool the heated dry goods. Cooling the Dry goods are carried out by means of cold air flowing from the exhaust hood towards the Supply air hood is routed through the cooling module and heated. The warmed Cooling air is at least partially blown into the supply air hood and thus the Warm air circuit supplied.
- At least the drying tower 3 of the drying system 1 consists of the one in FIG. 2 shown scaffolding.
- the support structure is essentially made of longitudinal struts 14 and Cross struts 15 formed by diagonally arranged tie rods 16 in the usual Way to be stressed.
- the supporting structure On its outer sides, the supporting structure is clad with panels 17, which in individual horizontal tracks are stacked and the Cover drying plant 1 completely.
- Fig. 3 shows a drying system with the drying tower 3 and the supply air or Exhaust hoods 2, 4 in cross section, in which the panels are each horizontally across the entire length or width of the drying system 1, so that only the Corners butt edges are present. This ensures high airtightness and further achieved a neat exterior view of the facility.
- Fig. 4 shows a sectional view of a sandwich panel 17, which is preferably is used as external cladding.
- the panel 17 is constructed in three layers, with an inner wall 9 and an outer wall 10 and an intermediate wall Insulation layer 11.
- the insulation layer 11 exists because of the Drying system occurring high temperatures not from foamed Plastic, but z. B. from mineral wool.
- the inner wall 9 of the panel 17th is made of aluminum or stainless steel to prevent corrosion.
- the vertical abutting edges of the panel sheets 17 are made with e.g. Aluminum covered.
- the sandwich panels 17 also have two, one on the outer skin / one the inner skin, horizontally running tongue and groove connections, which are also made of Metal and are thermally separated.
- the tongue and groove connection 18 consists of a along a longitudinal edge of the panel 17th continuous groove-like recess 18a in a narrow side of the panel, and an analog shaped one, in the recess 18a of the next panel fitting, in the longitudinal direction continuous projection 18b on the opposite narrow side of the panel 17.
- Such equipped panels 17 can be installed easily and quickly and offer a very good one Thermal insulation.
- the panels 17 are preferably attached to the frame by means of self-tapping screws from the outside through the panels 17 appropriate attachment sections are attached to the scaffold.
- the drying system 1 further comprises a dedusting device 6a, which in the The upper area of the drying column is arranged and integrated in the exhaust air chimney 6.
- the dedusting device becomes like all other additional Devices, e.g. B. blowers or fans, carried by the scaffold.
