Definitions

  • the invention relates to a manhole of a sewer with a device for preventing the escape of malodorous gases into the open.
  • Water is drained off via sewers, normally it is sent to a sewage treatment plant.
  • sewage channels for rainwater and those for process water often you can also find sewer channels that carry rainwater and process water. While pure service water channels can be made odor-tight, rainwater channels are necessarily open at the top so that rainwater can enter. Inlets are provided for this purpose, which are designed, for example, as street gullies. Through them, the rainwater enters the manhole and reaches the sewer.
  • the invention has set itself the task of avoiding that sewer smell can get outside.
  • sewer smells rising from the sewers, which escape through the inlets, are disturbing.
  • the canal smell is particularly intense on dry days, when people like to populate streets.
  • a closure such as that which is provided with the odor traps described would also have safety-related problems, since a gas pressure could accumulate in the sewer which could have dangerous effects. Even a normal walk through the sewer could become a safety risk. Such pressure or the accumulation of harmful gases could only be relieved by pushing the water trapped in odor traps outwards. However, this could in turn lead to large amounts of dirt.
  • the aim of the invention is therefore to provide a device of the type mentioned that constantly allows free entry and exit of gases from the manhole to the outside, but removes the channel odor from these gases and which also allows ring water to be unhindered by the inlet can get down into the manhole.
  • the object of the invention is to achieve this goal, which has not yet been formulated.
  • the object is achieved by a device in a sewer shaft of a sewer to prevent the escape of malodorous gases into the open, the sewer shaft having an inlet, for example a street gully, and below this inlet an essentially vertical shaft wall and the following further features are provided: a) a collar protrudes from the shaft wall inwards and upwards, which delimits an annular space which is open at the top and in which water normally collects and which has a free edge which forms an overflow edge, through which water reaches the sewer, b ) an annular floating body is provided which is located in the annular space, can move vertically and which normally floats in the water of the annular space, but lies as close as possible to a wall of the annular space when the annular space has dried out, c) an annular, gas-tight apron is provided that have a lower and an upper edge has, the lower edge being connected to the floating body in a sealed
  • the odor filter may or may not be permeable to water. It is normally not permeable to water. It is preferably protected at the top by a shield so that it cannot be wetted by water or covered or blocked by solids that are carried with the water. It is preferably designed to be exchangeable, so that an exhausted odor filter can be exchanged at certain time intervals.
  • the odor filter is designed as an activated carbon filter.
  • the apron is essentially designed so that it has the shape of a cylinder jacket. Together with the odor filter, which is preferably designed essentially as a flat disc, it forms a hat that is open at the bottom. The float is at the bottom of this hat. These parts are preferably interchangeable so that they can be removed upwards through the open inlet. This simplifies it Assembly and maintenance.
  • the apron is rigid, it carries the odor filter, which in this way requires no further attachment.
  • the apron is movable or elastic in the vertical direction. It is, for example, as a bellows, e.g. a rubber bellows. Their elasticity and their possibilities of movement in the vertical direction are dimensioned such that the floating body can move freely between its lowest position and its highest position within the annulus.
  • the odor filter is free from the movements of the float, it is held by a simple supporting part that protrudes from the shaft wall or the like. It is designed in such a way that it practically does not hinder the water falling down. In this version, the floating body does not have to bear the weight of the odor filter. The floating body can therefore be made much simpler and in particular much smaller than in the first embodiment.
  • All figures show a substantially vertical, cylindrical duct shaft 20 which is delimited by an inner wall 22.
  • the duct shaft does not necessarily have to run completely vertically, it is sufficient that a short section runs vertically or essentially vertically.
  • the sewer shaft is closed at the top in a street level 24 by an inlet 26, which is designed here as a manhole cover, also called a gully.
  • inlet 26 which is designed here as a manhole cover, also called a gully.
  • sand trap 28 directly below the inlet 26, it is already provided according to the prior art, it is to prevent leaves, dirt particles and the like from falling down.
  • a sand trap is of great advantage for the present invention because it results in essentially only water flowing further down.
  • a sand trap 28 as is already provided in most sewer ducts, is therefore of great advantage.
  • the odor barrier according to the invention is therefore preferably always below the sand trap 28. It has a collar 30 which projects essentially inwards and upwards from the inner wall 22. It is tightly connected to the inner wall 22 and made of a material, for example plastic or cast iron, which is both water and gas tight.
  • this collar 30 consists of an initially essentially horizontally extending section and a conically extending section, at the free end of which there is an upper current edge 32. All water flows down over this edge.
  • the collar 30 described in this way delimits an upwardly open annular space 34, which in the exemplary embodiment shown is additionally defined by a section of the inner wall of the sewer shaft. Water 36 accumulates in it. Furthermore, in this annular space 34 there is an annular floating body 38, which is designed like a lifebuoy. For example, it is made of polystyrene and has a dense outer skin. In the exemplary embodiment shown, it has a slightly conical part which interacts with the conical region of the collar 30. This has the advantage that when the annular space 34 dries out, a seal is formed between the collar 30 and the floating body 38.
  • the floating body 38 is dimensioned such that it has sufficient buoyancy for all parts, with which it is rigidly connected. This will be discussed in the following.
  • the floating body 38 is connected to a gastight apron 40. It is essentially designed as a cylinder jacket. It has a lower edge which is connected to the floating body 38 and an upper edge which is tightly connected to an odor filter 42. This is essentially designed as a flat, cylindrical disc. It closes the apron 40 at the top like a lid.
  • the buoyancy of the float 38 is now selected so that it can carry the weight of the odor filter 42 and the apron 40, but also its own weight, when the annular space 34 is filled with water, without being pressed onto the collar 30, that is to say it remains in a floating state.
  • a guide 44 is additionally provided. It has the effect that the unit comprising the float 38, the apron 40 and the odor filter 42 can essentially only move in the vertical direction, that is to say in the direction of the double arrow 46.
  • the guide 44 shown here is only one example of a possible training. It consists of three star-shaped, essentially L-shaped support parts which protrude from the collar 30 and then run towards the center. It supports a central part 48, on which the odor filter 42 can move up and down.
  • FIGS. 2 to 4 differs from the previously discussed embodiment according to FIG. 1 in that the apron 40 is now designed to be movable or elastic in the vertical direction, which makes it possible to arrange the odor filter 42 in a stationary manner. The weight of the odor filter 42 then no longer has to be borne by the floating body 38. Otherwise, the basic training is unchanged.
  • FIG. 2 shows the annular space 34, which is at least partially filled with water 36 and in which the floating body 38 is in the floating state.
  • the apron 40 is designed as a rubber bellows.
  • the odor filter 42 is carried by a supporting part, which in turn is supported on the collar 30 or a corresponding holding part. This supporting part is designed in such a way that the odor filter 42 can be easily replaced, for example it is only removed upwards, so it lies tightly due to its own weight.
  • the floating body 38 floats within the annular space 34, which is no longer completely filled with water 36.
  • the floating body 38 floats within the annular space 34, which is no longer completely filled with water 36.
  • FIG. 4 shows the state that water 36 flows continuously from above, the annular space 34 is completely filled with water 36, which flows down over the overflow edge 32.
