In the cleaning chamber 9 in the direction of movement of air in a checkerboard pattern are, us is set out on the feet (figure 1-7 not shown) vertical removable perforated basket 25, filled with granules of pumice 26, made of steel slag module basicity M>1 diameter from 20 to 40 mm, and against each basket 25 posted by flushing device 18, the latter in the direction of the air cart 25 in the roof 2 is arranged in the exhaust hole 27 that is connected to the exhaust shaft 28, which is placed inside the ionizer 29, exhaust fan 30 and which is provided at the level of human growth window 31 with distributive lattice 32 facing the pedestrian movement, and the intake grille 10 camera irrigation 8 communicates with the channel stormwater LK, arranged at the side edges of the roadway PU, which, in turn, reported to the atmosphere roadway through its lattice RK.
Underground street mount conditioning underground pedestrian part of the street, the busiest transport, so that the end of the camera irrigation 8 adjacent to the side wall of the channel stormwater LK on the site, closed bars RK, on the border of the road and the pedestrian part of the street, intake grille 10 were in the top part of the right side of the storm channel LK and was facing the roadway and distribution grid 32 facing in the direction of the pedestrian, the roof 2, which represents a removable concrete covered is e, was on the level surface of the sidewalk, Luke 3 was in the neutral zone, then connect the underground street air conditioning to all communications.
Cleaning the outside air from the harmful components of exhaust gases of motor transport and dust in underground street the conditioning is carried out as follows. The outside air is sucked from the surface layer of the atmosphere, which is the most contaminated, through the lattice RK channel stormwater LK and intake grills supply 10 fan 11 in the spray chamber 8, where the speed drops rapidly moves down the contacts in the cross-current with water particles coming from the injectors (figure 1-7 not shown) irrigation device 17, the entire height of the camera irrigation 10, hydrated and partially cooled. At the same time, in parallel to the above described processes, in the spray chamber 8 is trapping water particles of dust and soot, the interfacial contact of the sprayed water with air, resulting in the absorption of this water, carbon dioxide, chemical interaction of nitrogen oxides, sulfur oxides, ozone, oxygen, water between the gas and liquid phases, chemisorption formed nitrogen dioxide (NO2) and sulfur dioxide (SO3water (H2O) with the formation of nitric (HNO3) and sulfuric (H2SO4) acids Formed acidified water, saturated with carbon dioxide from mechanical impurities, flows into the sump 5, is mixed there with the previous acidic water, where part of this mix equal quantity of water supplied for irrigation, together with the sludge through the drain pipe 20 submersible pump 19 is supplied to the channel, storm sewer Luke, and the other part of the upper layer of water in the pit 5 enters the circulation pipe 14 connected to the feed pipe 13, is mixed with the feed water, the amount of which is determined by the number of absorbed carbon dioxide from the outside air, after which the mixture of fresh and acidified water pump 12 through the discharge pipe 15 is routed back into the irrigation device 17 camera irrigation 8. Purified from carbon dioxide and some nitrogen and sulphur oxides, dust and soot, hydrated and partially cooled outdoor air with particles acidified water from the chamber 8 through irrigation window 7 enters the cleaning chamber 9 passes in a horizontal direction through the perforated basket 25, filled with granules of pumice 26 made of the main metallurgical slag. Adsorbed from the outdoor air molecules of nitrogen and sulphur oxides in the pores of the granules 26 have high reactivity, due to their interaction with the surface of the adsorbent Gras is St slag pumice 26 [Nenitzescu K. General chemistry - M.: Mir, 1968, s], therefore, are oxidized with oxygen at a rate greater than that in the gas phase with the formation of readily soluble in water NO2and SO3that, in turn, interact with particles acidified water remaining in the pores of the pellets 22, with the formation of the corresponding acid HNO3and H2SO4. In addition, on the surface and in the pores of the granules 26 are deposited fine particles (dust, soot, etc.), then cleaned and dried air is additionally exempt from carry out water droplets due to their deposition under the action of gravity in a vertical hole 28, when passing through the ionizer 29 enriched light air ions and an exhaust fan 30 through a distribution grid 32 of the window 31 is served in the pedestrian zone of the street.
At the drop of activity of the granules of pumice 26 in perforated baskets 25 they are subjected to regeneration, which is carried out during the hours of minimum traffic flow (for example, at night) in the very air. The regeneration process consists of washing the granules 26 from dust particles, soot and acid water containing entrapped oxides of carbon, sulfur and nitrogen. Washing is carried out by feeding water into the cleaning chamber 9 through the discharge pipe 16 and washer 18, and contaminated wash water by gravity down the inclined bottoms the qu of the pallet 4 in the sump 5, where the drainage pump 19 is removed in the channel stormwater LK.
The amount of washing water and the washing time set empirically. Complete replacement of the granules of pumice 26 conducted one time per season. Inspection and repair of major equipment are carried out through the sunroof 3.
As the source of the water supplied to the spray chamber 8 for the absorption of carbon dioxide in large quantities, you can use the water stations pumping of groundwater is underground (provided there is no harmful impurities), and discharged into the storm sewer system LK acidified water,1 in connection with a high content of carbon dioxide in it will contribute to the processes of photosynthesis [9, com VP, etc. Biochemistry. - M.: bustard, 2004, s] in the fields of irrigation of municipal wastewater treatment facilities.
Dimensions and screening area gratings RK stormwater LK and intake grille 10 underground street conditioning is determined by its specified performance and outdoor air pollution. The cross-sectional area, the number and volume of perforated baskets 25, porosity, size, and number of granules of pumice 26, the capacity and performance of the fans 11 and 30, ionizer 29, pumps 12 and 19, the volume of pit 5, the adsorption capacity of the camera 9 cleaning, water consumption for irrigation in the spray chamber 8 and recycling are determined by the manufacturer of the spine through the air, its pollution and the required degree of purification. However, underground street air conditioning is preferably made in the form of typical sections with the case of concrete structures, each of which can work separately, which allows you to increase or decrease the performance of the installation depending on the environmental situation in the street.
Thus, the present invention allows the placement of street air conditioning under the ground, without cluttering of street space by unauthorized constructions and to use the existing storm sewer system to remove acidified water, which gives the possibility to exclude the construction of additional sewer systems and increases the economic and ecological efficiency of underground street-conditioning.
