Definitions

  • the invention relates to a device for moistening, cleaning and cooling gases, primarily air, with a filter layer arranged in the gas stream and a device for applying it to liquid.
  • Such devices are used primarily, but not exclusively, for the ventilation or air circulation of greenhouses. It is important that adjustable outside air and / or recirculated air is treated.
  • the filter layer arranged obliquely to the air inflow direction and / or air outflow, the device for loading the filter with liquid consists of a nozzle which is arranged upstream of the filter but downstream of a fan.
  • the filter layer is regularly arranged obliquely to the flow direction, so that a larger filter passage area is available.
  • filter it is a matter of gas- or air-permeable material layers of any structure, which not only filter the air or gas, but are also provided with liquid, in order to humidify the air from the surface, which has been significantly enlarged by fine division. During humidification, the air or gas is also cooled.
  • a device of the generic type is characterized in that at least one cage with a polygonal cross section, closed at the bottom, is arranged in a cuboid-shaped housing with upper inlets for outside and / or circulating air, the upper side of which is opened by a centrally arranged fan with the release of a wide one outer annular gap is only partially covered and under the fan an annular spray nozzle for the distribution of liquid, primarily water, is arranged on the inner cage wall formed by a filter layer, the housing in its lower part with air outlet openings and in its upper part, the cage partially overlapping part is provided with a return of the air emerging from the cage to the annular gap on the fan.
  • the cage is preferably cylindrical.
  • the arrangement of the filter layer in the wall of a cylinder with a polygonal or circular cross-section results in a completely uniform application of all areas of the filter, even if the fan is arranged slightly above the cylinder and thus the filter layer, so that a very compact design and a small construction volume is achieved.
  • Due to the shape of the filter layer mentioned its wetting through an annular spray nozzle is also extremely uniform and in all areas such that the air passing through it is optimally moistened.
  • a particular advantage is achieved that the air emerging from this in the upper region of the cylindrical filter is returned due to a corresponding overlap, to the annular gap which exists between the fan and the upper opening of the cylindrical filter. A vacuum is created on this ring plate by the air flow generated by the fan and directed into the cylinder.
  • Ambient air is sucked in due to the induction effect of this negative pressure.
  • the air that is sucked in is air that exits from the upper regions of the cylindrical filter and, where appropriate, has cooled down, if it is already moistened. This air is thus repeatedly pushed through the filter and thus repeatedly humidified and, if necessary, cooled. This results in an improvement in the degree of humidification of up to 10% and thus possibly also an improved cooling of the air, which exits the device in a valid manner.
  • the invention not only is a compact design of the entire device achieved, but also a significant improvement in efficiency.
  • the upper part 2 is designed as an air duct box.
  • One about a pivot point 7, about a quarter-circle rotatable flap 8 serves to mutually shut off and open the two inlets 3 and 5, intermediate positions being of course also possible, so that the two openings 3 and 5 are partially open.
  • Two cylinders 9 and 10 are arranged in the housing below the air guide box. These cylinders are formed from an upper ring 11, which can have an angular profile and a lower end plate 12 with the same outer diameter as the upper ring 11. Between the upper ring 11 and the bottom 12, a cylinder is formed, which consists of the filter medium consists, for example, of a foam with open pores. This foam cylinder can be provided on its outer surface with a reinforcement, for example in the form of a coarse mesh fabric made of any material.
  • the foam cylinder is held between the ring 11 and the bottom 12 by rods 13, which are equally spaced around the circumference and are stuck both on the ring 11 on the one hand and on the bottom 12 on the other. At least two rods 13 are fastened in such a way that they can be easily removed in order to be able to remove the filter cylinder held between them, either for replacement or for washing and cleaning.
  • the filter cylinder can also consist of different layers, for example have a spacious non-woven structure in the interior and be formed from fibers and be formed in an outer layer from foam with open pores.
  • the filter can also consist of different types of filter media in the height division, i.e. that, for example, the cylindrical filter in the upper part consists of a filter medium which has a lower air resistance than the filter medium in the lower part. The meaning of this measure is explained in the following explanation.
  • the housing covers below the air guide chamber 2 with the same floor plan the cylindrical filter or 9 or 9 and 10 with walls 14 and 15 on the long sides, and walls 16 and 17 the narrow sides in such a way that a lower region 18 of the cylindrical filter is not covered.
  • the dimensions are such that the housing walls 14 to 17 are at a distance 19 from the cylindrical filters 9 (and 10), so that an air duct 19 is formed here.
  • the wall 15 is provided with flaps or doors for opening.
  • the lower edges of the side walls 14 to 17 are provided with end covers 20 which are guided against the cylindrical filter 9 or 10 and can rest against this.
  • These covers 20 are expediently bulged in such a way that they are adjustable in height with a wall part which slides telescopically behind the lower edge of the fixed wall, so that the free lower region 18 of the cylindrical filter is variably adjustable, ie that it increases or can be made smaller.
  • additional openings 21 can also be arranged in a fixed housing wall, for example the wall 14, which serve as outflow flaps for the air and are expediently opened as far as desired by displacement.
  • a vane fan 22 is arranged above the upper open part of the cylindrical filter, the motor of which is indicated by 23.
  • the fan 22 does not sweep over the entire circumference of the cylindrical filter with the rotating circle 24 of its blades - rather there is an annular gap 25 therebetween.
  • the ratio of the width of this annular gap 25 on the fan to the diameter of the cylinder 9 or 10 is approximately 1: 6.
  • the air flow generated by the fan 22 and directed into the cylindrical filter sucks air, to a certain extent secondary air, through the rinse gap 25, which air is also pressed into the space surrounded by the cylindrical filter. Due to the above-described design of the housing, this air is discharged from the air duct 19 and thus from the upper area of the cylindrical Filter sucked in.
  • an intermediate floor 26 is arranged between the fan or between the outer circumference of the circle, which is swept by the fan blades b, and the inner sides of the housing walls. The mounting of the fan is expediently supported on this intermediate floor 26.
  • This intermediate floor 26 closes the air ducts 19 within the outer wall of the housing at a distance above the ring 11, which carries the upper edge of the cylindrical filter, and covers the annular gap 25, so that the "secondary air, which is induced by the air jet generated by the fan, is sucked in from the covered upper area of the cylindrical filter, so there is a kind of air circulation in the upper part of the filter, but this air which has been sucked in again tends to the lower area of the cylindrical filter due to its greater density due to humidification and cooling arrives so that it is finally blown out after repeated passage through the filter in the lower region 18 of the filter.
  • annular spray nozzle 27 Arranged underneath the fan is an annular spray nozzle 27 which humidifies the air blown in by the fan and also uniformly humidifies the filter walls from the inside, so that the air pushed through is in turn humidified there. Excess liquid runs down inside the filter, is collected by the bottom 12, which closes the filter down, and flows in the center of the bottom into a collecting vessel 28 and a drain 29.
  • the filter is arranged cylindrically on the basis of the exemplary embodiment described above.
  • the filter can also be designed with a polygonal layout, it can be octagonal, for example, if, for example, a filter medium has to be used which only lies in mats and cannot be bent into a cylinder. Individual flat sections of the mats are then joined together to form an octagonal polygon, for example, the mats being supported on the rods 13 at the abutting edges which are glued together.
