The invention relates to sanitary engineering and relates to situations where the underground structure has been used as shelters from air attack for the population of the metropolis.

The accumulation of extremely large masses of people and their long stay in the underground areas dramatically increases the requirements for the ventilation of the underground, especially the ventilation of sanitary facilities. It is not excluded that it may give the situation, when in a particular area of the metropolis cannot be used for ventilation outside air. In this case, there is a need for reusable tunnel air, keeping it clean in the recycling process.

From the patent and technical literature there are known various systems to provide comfortable conditions for people in civil defence facilities, such as Sanitary installation" (see USSR author's certificate 1698384 in class. E 03 D 1/00, publ. in BI 46 (1991)), which use waste water sinks to flush toilets is a" (see international application WO 99/43897 class E 03 D 9/04, 9/052 publ. 02.09.99 g ), which provides the possibility of rapid adjustment by the user of the intensity of the removal of contaminated air from the interior of the lavatory, and directly from the cavity of the toilet. In a discharge duct mounted filter cartridge with a metal filter element.

With a large number of "seats" in a public restroom is not economically feasible to install fans and replacement filters in each bowl.

The famous "exhaust ventilation System in toilets" (see the proposal of Japan to the invention 3-34528 class E 03 D 9/05 publ. 23.05.91 g) containing a vertical pipe for supplying cleansing water to the toilets and drainage of dirty water, placed in a common riser. Pipes are separately communicated with the corresponding horizontal pipelines for cleaning fluid (water) and horizontal discharge pipes the contents of the bowls (fecal fluid). Each of the horizontal piping for the cleaning liquid provided with a vertical inlet pipe communicated with the storage tanks standard toilet bowls and urinals. A horizontal line is about blocking the knee and parallel to it the pipe mechanism remove odors from toilets by fans, and the said pipe is provided with regulating devices of the amount of exhaust air is emitted into the atmosphere.

It is clear that the remote air is replaced by outside air, which is in a state of emergency may not be valid.

The closest analogue is the ventilation system and clean sanitary facilities in underground structures underground, containing piping for supplying cleansing water and drainage (see Estuaries Y. A. Subways. - M: all-Union NP Union of Ministry of Railways, 1960, S. 288, 296).

The present invention is to provide comfortable conditions for the masses of people seeking refuge from air attack in underground structures underground.

This task is solved in that the ventilation system and clean sanitary facilities in underground structures underground, containing piping for supplying cleansing water and drain dirty, further provided with a fan to exhaust air from the health unit, the fan together with the suction grille and the motor attached to the wall of one of the premises of the sanitary node so that its wybron containing a replaceable cartridge with copromotor. In addition, the system further comprises a fecal camera sanitary units with a sloping bottom, in the bottom part of the bottom of which is rigidly fixed bearing for sewage pump installed so that its inlet facing down, and the hole can be communicated through the pipeline with the city sewer.

Specified bearing made of rods rigidly mounted on the metal base along the Central vertical axis at various distances from each other in accordance with an asymmetric arrangement in terms of flange holes sewage pump, each of the rods are provided with a platform to support a flange of the pump and finger threaded Central axis of which coincides with the vertical Central axis of the rod.

In the floor of the premises sanitary site is provided with sunroof cover, the center of which is vertically coincides with the center support, and the orifice diameter manhole exceeds the outer diameter of the cavity of the pump installed in the faecal chamber.

At the point of projection of the vertical line passing through the center hatch on the ceiling of the room, sanitary fixed block for cable, one end of which may be attached to the eyelet sewage pump, and the other, the bathrooms in the floor and provided with screw holes.

The air inside the lavatory is purged from hydrogen sulfide, ammonia and pornopanda elements with filter replacement cartridges copromotor (filler for marine filters). Cassette mounted on the fan inlet mounted on the wall of one of the premises of the sanitary unit, preferably in the bathroom with wash basins and urinals. Under the premises of the sanitary units provided by the faecal chamber with inclined inward they, in the lower parts of which provided support in the form of a vertical pin for sewage pumps. In the flange of the inlet of each sewage pump provides slots for fingers vertical pins that guide in a predetermined spatial position of the pump. The release of fecal fluid carried in the pipe in the sewers. For lowering fecal pump and its rise from this camera in the floor provides a manhole of adequate size, cover with lid, and over the hatch in the ceiling, reinforced block mechanism and a floor mounted anchor for the winch. For washing glasses booths summed up water, water from which is used for simultaneous leaching of faecal chamber and pump.

On the adjacent drawing shows:

Fig. 3 is a vertical section of a sanitary unit with faecal chamber and the pump.

Fig.4 - two projections support the fecal pump.

Ventilation and sanitary cleaning of site 1, located in the underground construction underground near the tunnel 2 provided with sanitary unit passages 3 and 4, contains the fan 5, the entrance of which strengthened the filter housing 6 (see Fig.2) to accommodate interchangeable cassettes 7 copromotor, absorbing ammonia, hydrogen sulfide and fecal odors. The fan inlet 5 blocked intake grille 8, and the output connected to the duct 9, which pass through 4 taken in the tunnel 2. The fan 5 is driven by a motor 10. Sewage pump 11 (see Fig.3) installed in the faecal chamber 12 with an inclined bottom, the lowest point is reinforced bearing 13, separately shown in Fig.4. The inlet of the pump 11 is facing down, and the output is equipped with a coupling 14 for connection to a pipe 15 provided with inlet 16 (see Fig.1) urban Sewerage. In the floor-care unit provides Luke 17 appropriate size for lowering and lifting sewage pump 11. Luke 17 is closed by a cover 18, which has a hermetic elastic strips at the stop 19, where are the sinks 20 and urinals 21. In the ceiling of the room 19 opposite the hatch 17 fortified unit 22, through which can be skipped rope 23 (depicted by the dotted line). Three 23 one end can be attached to the pump 11, and the other to the winch (the drawing is not shown). For temporary fixing of the winch in the floor space 19 is mounted a metal armature 24 with the screw holes. Support 13 (see Fig.4) made of metal rods 25, vertically and rigidly mounted on the plate 26 so that in terms of their location asymmetrically. The rods 25 top site 27 to support a flange of the pump 11 and the fingers 28 are threaded for rigid attachment of the pump 11 on the support 13.

In order to lower the pump 11 in the faecal chamber 12 is fixed to the winch on the floor of the space 19 of the anchors 24, attach the cable 23 to the winch, allowing them to pass the free end through the block 22 and is fixed to the lug 29 of the pump 11. Open the hatch 17 and using the winch lowered the pump 11 in the faecal chamber 12 on the support 13 so that the holes of the flange of the pump with the fingers 28. Because of the asymmetrical arrangement of the fingers 28 in the plan on a support 13 this can only be done at a certain spatial position of the pump 11, the holes in the flange which also asimage will coincide and the pump 11 may be quickly attached to vybranou pipeline 15 to its outlet. Nuts 30 fix the pump 11 on the support 13, connect the electric pump to the mains, disconnect the lug 29 of the cable 23 and remove the winch. Then close the hatch 17 cap 18.

After the termination of the emergency washed with water from the water when the pump 11 fecal chamber 12 itself sewage pump 11 through the hole 17. Disconnect the pump from the clutches 14, Unscrew the ring nut 30 with the fingers 28 and by means of the winch remove the pump from the faeces chamber 12. Tapes copromotor change during operation of the fan 5 according to the instructions.
