Definitions
- the invention relates to a method and a device for cleaning even slightly polluted air quantities, e.g. in tunnels, street canyons, traffic structures and rooms.
- the gaseous and particulate pollutants released during the operation of internal combustion engines pollute the air considerably, so that measures for reducing pollutants are necessary.
- this task is solved by supplying fresh air and polluting air e.g. over fireplaces or similar is released to the environment.
- fresh air is used to dilute the e.g. supplied with polluted tunnel air; on the other hand, the selective release of pollutants at tunnel exits and / or exhaust air chimneys, especially in cities and other environmentally sensitive areas, leads to a considerable deterioration in air quality.
- bio-filters in activated sludge, in an organic fixed bed or on a carrier / nutrient medium (PS 32 27 375, PS 42 35 591 and PS 41 29 101),
- the invention has for its object to build up the cleaning of large-volume and lightly polluted air volumes, for example in tunnels, other traffic structures and the above-mentioned rooms and systems, by combining the methods, the arrangement (sequence) and by the fluidic design of the cleaning elements that a cleaning of the air is possible with little investment and operating costs (cf. Fig. 1, 2, 3 and 4)
- the method and the device according to the invention for cleaning large and slightly polluted air quantities is characterized in that air cleaning elements of modular design are decentralized all or part of the
- the circumference of the tunnel and the length of the tunnel are installed one after the other and remove particles and harmful gases from the tunnel air thanks to the flow-related design of the cleaning elements on the tunnel wall
- Air inlet and air outlet is a circulation of air through the modules without
- Each cleaning module is sized according to the size and the flow technology
- a central ventilation of the cleaning modules is possible if necessary (e.g. traffic jam) or in the event of a fire.
- the filter elements are combined in this order: coarse filter, controlled electrostatic! Filters, mechanical filters with switchable washer, bio-filter with a specially designed surface as a carrier system with a switchable gas filter (e.g.
- the modules form elastic obstacles that can absorb part of the kinetic energy; the load on the tunnel wall is reduced.
- the cleaning effort for the tunnel wall (now the cleaning module surface) is reduced to a minimum due to the low pollutant content of the tunnel air in the entire area
- the electrostatic filter is controlled as a function of the particle concentration (on-line, ionization current), as a result of which longer service lives are achieved and operating costs (energy) are reduced.
- the washer in the mechanical filter with a special nozzle system is switched on according to the invention if - the air humidity is too low, - the agglomeration of the particles is insufficient, - in the event of fire and
- the bio-filter is designed according to the invention by the shape and surface of the carrier system in such a way that, on the one hand, a stable bio-film for the degradation of the noxious gases is possible with minimal pressure losses in the nutrient and air circulation, and on the other hand self-cleaning of the Carrier system can take place.
- the effectiveness of the cleaning module can be increased by an increased nutrient and / or water cycle and the filter can be temporarily protected from high temperatures
- the fire is signaled early by the on-line particle concentration measurement and the particle size distribution measurement, which is used for controlling the electrostatic filter (smoke in the cleaning element)
- FIGS. 1-4 Exemplary embodiments for a tunnel system are shown in FIGS. 1-4.
- Each cleaning element of the system consists of the three segments 1-3
- Figure 2 shows the associated side view (at the decentralized air inlet and outlet)
- FIG. 4 The reverse case of the decentralized air inlet with a central air outlet is shown in FIG. 4 in a sectional view.
