Definitions
- the invention of the present application relates to a process for venting and / or exhausting flue gas in case of danger with fire in a tunnel, especially car or train tunnel.
- the invention further relates to a suction system for a tunnel, in particular Car or railway tunnel, with an exhaust duct with corresponding in the tunnel mouth exhaust air duct openings.
- the concerns Invention a use of a device for detecting and aspirating of fluids.Tunnel for motor vehicles obtained in the receding Europe increasingly important as links between North and South, East and West. Even in the urban area is expected that in particular for the reduction of noise and exhaust pollution or as accelerated traffic route in city thoroughfares more and more roads Underground constructed as a tunnel or laid in an underground tunnel become.
- a fire ventilation system plays a central role here.
- This task is accomplished by a method of o.g. Type with the in claim 1 characterized features solved.
- a flow in particular a vortex flow is formed in particular in the upper region of the tunnel cross-section sucked air radially or tangentially and an exhaust duct at one Ceiling of the tunnel is fed or that inside or below one Area, in particular an upper third of a tunnel cross-section a parallel to the tunnel longitudinal axis and / or transverse Detecting flow is formed, which is a uniform detection ensured over the length of the detection flow, in particular a Vortex flow, extracted from the radial or tangential air and a Exhaust duct is supplied to a ceiling of the tunnel.
- the o.g. Task is further by a suction of the o.g. Kind of with the solved in claim 6 marked features.
- a device for influencing an air flow in the region of the exhaust air duct opening and / or in a tunnel area below the exhaust duct opening is arranged.
- the exhaust duct is arranged on a ceiling of the tunnel.
- a uniform suction across all suction openings is achieved by that the exhaust duct on the ceiling of the tunnel in particular axially parallel and centrally arranged to this or offset laterally.
- the exhaust duct has an exhaust opening to the environment.
- the device comprises for influencing the air flow a stabilized swirl flow at least partially enclosing and this swirl flow leading coat, which is formed, for example, part-cylindrical.
- this swirl flow leading coat which is formed, for example, part-cylindrical.
- points the mantle is extending in the axial direction with respect to the mantle Inflow opening and a plurality of suction openings, which with the Exhaust duct opening are connected.
- the suction openings are for example arranged tangentially or radially to the swirl flow.
- each suction opening has a tube, which extends into the mantle.
- Cross smoke extraction is achieved by superposition of the vacuum fields in the two jacket pipes, which led along the tunnel wall are and possibly by a flow around the partition skirt, so that too In the transverse direction with respect to the tunnel smoke is sucked, since this vortex flow directly and actively transported the smoke to the mantle before the smoke can spread further.
- Tunnellijnsraum spaced apart aprons in one upper area, in particular in the upper third to fourth of the tunnel cross-section intended.
- Each of the dividing aprons extends at least to the lower edge of the jacket tube.
- a device for manufacturing an air sink or a negative pressure, in particular a fan, intended in the exhaust duct, a device for manufacturing an air sink or a negative pressure, in particular a fan, intended.
- the invention further provides a use of a device for Capture and suction of fluids, in particular air and / or other Gases, with a stabilized swirl flow at least partially enclosing and this swirl flow leading coat, as a suction system proposed for flue gas in a tunnel.
- the inside or below an upper portion of the tunnel cross-section formed flow in formed the middle of the tunnel. It has been shown that by the direct Extraction of flue gases from a fire source from below above and the discharge of flue gases directly above the fire particularly effective smoke extraction can take place.
- the said flow is advantageously vertically below the Exhaust duct openings formed so that the flue gases on the shortest Get routes in the exhaust duct and from there with a high volume performance can be removed.
- the device for influencing an air flow in the Center of the tunnel arranged.
- a particularly efficient extraction can be achieved.
- the said device for influencing an air flow vertically below the exhaust duct opening arranged the exhaust duct. In this way, the Flue gases on the shortest way up through the exhaust duct openings and be transported from there into the exhaust duct.
- the device for Influencing an air flow symmetrically with respect to the longitudinal axis of the tunnel.
- This can be a substantially symmetrical Training the suction flows are achieved in the tunnel, so that over the entire width of the tunnel a uniform smoke extraction can be done.
- the illustrated in Figure 1 embodiment of a suction 100 for Detecting and aspirating fluids in a tunnel 10 comprises at one Tunnel ceiling 12 an exhaust duct 11 with at least one exhaust duct opening 14, which is connected to the exhaust duct 11.
- This exhaust duct 11 extends, for example, below the tunnel ceiling 12 parallel to the axis to the tunnel 10, has several associated with the tunnel 10 exhaust duct openings 14 and an opening into the environment, not shown Exhaust opening.
- the exhaust system 100 further includes a preferably in the upper third to quarter of the tunnel cross-section extending partition skirt 16, wherein in the longitudinal direction of the tunnel 10th spaced from each other a plurality of separation aprons 16 are arranged, which divides this upper area of the tunnel into several segments, for example divide each 100 m.
- a total suction is at, for example, one or two still open exhaust duct openings 14 for the removal of flue gas available, because it is an experience that for sure Flue gas removal from the area of the source of fire approximately the four- to fivefold amount of air volume must be extracted than on flue gas volume arises from this source of fire.
- the optional opening and Closing the exhaust duct openings 14 makes it possible that not the entire plant for all segments at the same time on such a high Volume flow rate must be designed, but that it is sufficient if this volume throughput per segment with only one or two open Exhaust duct openings 14 is achieved.
- Volumen is usually sufficient in a fire opening an exhaust duct opening 14 which that segment of the tunnel 10th is assigned, in which the fire is localized. Unless the source of fire takes place at a transition from one segment to the next the Rauchgasausaugung expediently in both together bordering segments.
- a baffle 30 is arranged, which has a Channel 32 with the tunnel wall 28 with an approximately triangular cross-section forms and the flue gas stream to the suction opening 24 in the false ceiling 34 leads.
- FIG. 2 shows in cross section a further extraction system according to the present invention Invention. Same parts as in the extraction system of Figure 1 are provided with the same reference numbers. The basic structure and the basic function of this extraction system correspond Figure 1, so that they need not be explained again.
- the essential difference from the extraction system according to FIG. 1 is that that the device 18 for generating a swirl flow in the middle the tunnel 16, that is centrally along the longitudinal axis of the tunnel is arranged. As a result, this is the case in a suction Flow pattern changed. As has been shown in experiments, it is regarding the efficiency of the suction surprisingly significantly improved.
- the basic flow pattern is indicated by arrows in the figure. From this it can be seen that those emanating from a source Exhaust gases on relatively short and direct route to the device 18 and from there to the exhaust duct 11 can pass.
- the device 18 consists essentially of two symmetrical with respect the tunnel longitudinal axis arranged cylindrical sheaths 22, which are open at the top and allow the entry of gases there.
- the coats 22 stabilize a swirl flow in their interior. Such a flow is based on a photo from a series of experiments in the field of application of Figure 2 shown.
- a suction 14 Centrally above the two shells 22 is centrally located a suction 14, which leads into the exhaust duct 11. About the exhaust duct opening 14th can suck air tangentially from the swirl flow in the coats 22 become.
- the exhaust duct 11 is also centrally along the longitudinal axis of the tunnel 16 arranged, giving a total of short distances of the extracted air be achieved by the device 18 in the exhaust duct 11.
