Definitions

• the invention relates to a method for minimizing odor emissions from a compost heap arranged in a closed composting halls and to a device for carrying out the method according to the preamble of claim 6.
• TZBLATT attached suction or suction device are removed and connected to a ventilation system for rent.
• the entire indoor air volume must be replaced several times per hour. This requires a very high suction power with a correspondingly high outlay.
• the object of the invention is now to improve the type of suction and, in particular, to reduce the amount of suction required.
• Subclaims 2 to 5 contain supplementary procedural proposals and subclaims 7 to 12 special embodiments.
• the idea of the invention is based on the fact that the gases or air emitted during the processing of the rents in the immediate vicinity of the processing equipment from the rents are to be extracted specifically at the point of origin so that odorous substances and moisture are not first distributed into the rotting hall and have to be extracted there with greater effort.
• the extraction at the location where the emission occurs can be carried out according to the invention with a mobile or movable suction device, namely: a) by means of a suction device which can be moved in all possible directions above the rent independently of the rental processing device or b) by means of a jointly with the rental processing device, which can be experienced and possibly permanently connected to it, the suction device, which consists of one or more individual hoods or a ring line with a large number of suction nozzles.
• the movable suction device can be connected to a filter, namely: a) via flexible connecting lines, for example hoses to a stationary filter or b) via outlet connections in the immediate vicinity of suction openings of the supply air line of the stationary filter or c) to one the filter arranged in the rental processing device or d) to a filter traveling in parallel with the rental processing device.
• the cleaned gases emerging from the mobile filter enter: a) into the hall or b) to a stationary exhaust air line connected via flexible lines or similar connections or c) in the immediate vicinity of the intake manifold of the stationary exhaust system.
• the moisture contained in the discharged gases can largely be separated off in suitable cooling traps or condensation devices, namely: a) before the filter or b) after the filter.
• both the unpleasant odorous substances and the aforementioned health-endangering bacteria and fungi can be largely removed from the extracted gases in suitable compost filters.
• the air germ load after the filter is approximately in the range of normal outside air.
• FIG. 1 shows the movable suction device 2 according to the invention above the work station of a bucket wheel loader 3.
• FIG. 2 shows the arrangement of a movable suction device 2 on a bridge 8 spanning the compost heap 1 in direct connection with a loosening device 6.
• the suction device is shown as a ring line 15 surrounding the processing point and connected to a movable biofilter 14.
• the suction devices 2 and 6 are each connected to a movable bridge 8 spanning the compost rents with the aid of a trolley 13 which can be moved transversely thereto. This trolley travels with rollers 5 on the running rails 4.
• this trolley travels with rollers 5 on the running rails 4.
• these flexible lines can be arranged either on the height-adjustable cross member 7 or on the bridge 8.
• the ring line 15 is connected to the intake manifold 16 via a fan to the biofilter 14 which is arranged on the bridge 8.
• This biofilter can be loaded with the usual compost filter material in a simple manner from the usual stationary conveying member 10 or another conveying member and can be emptied again, for example, by simply tipping over.
• FIGS. 2 and 3 also show the lifting members 9 known per se for height adjustment of the cross member 7 with the loosening device 6 attached to them, as well as the hopper 12 and the conveying member 11 for the removal of the compost material. LIST OF REFERENCE NUMBERS
