Abstract
The utility model discloses a novel tunnel ventilation device which comprises air suction ports (1), butterfly valves (2), an air suction pipe (3), draft fans (4) and a tunnel (5). The novel tunnel ventilation device is characterized in that the air suction pipe (3) is radially mounted at the top of the tunnel (5), the draft fans (4) are mounted at two ends of the air suction pipe (3), the air suction ports (1) are arranged on the wall of the air suction pipe (3), and the butterfly valves (2) are mounted at positions adjacent to the air suction ports (1) which are arranged at an internal of 50m. By the aid of the novel tunnel ventilation device, tunnel (5) noise can be lowered, power consumption is reduced, and ventilation efficiency is improved. Further, the novel tunnel ventilation device can keep ventilation even under the situation of roof collapse, blockage, firing and the like of the tunnel (5).
Description
Technical field
The utility model relates to a kind of tunnel ventilation system, relates in particular to a kind of novel tunnel ventilation installation.
Background technology
Good air conditions is the necessary condition of traffic safety in the traffic tunnel, and ventilation is in order to reduce the concentration of pernicious gas in the tunnel or pollutant, to guarantee running safety and comfortableness.
The common draft type of existing tunnel has following several kinds:
Natural ventilation: so-called natural ventilation is meant to be got rid of pernicious gas and flue dust through the piston action of the automobile of process in the tunnel and natural wind action in the tunnel.Adopt the natural ventilation pattern to be subject to the size of the vehicle flowrate tunnel in, and the air-flow that the unstability of natural wind and complexity can influence in the tunnel greatly exchange.
Vertically formula is ventilated: it is to introduce fresh air from a hole that so-called vertically formula is ventilated, through the decontaminate mode of air of another hole.This mode, air pollution degree is increased to being linear to exporter one by inlet, and the entrance pollution concentration is minimum, and it is big to survey pollution concentration in the outlet.Meet fire situation and can cause exit concentration high, smoke evacuation inconvenience.Existing vertical formula ventilator power ratio that adopts of ventilating is bigger, and cost is than higher and noise pollution is serious, economic inadequately environmental protection.
Summary of the invention
In order to solve above technical problem; The utility model provides a kind of energy-conservation, noise reduction, novel tunnel ventilation installation efficiently, is made up of inlet scoop (1), butterfly valve (2), aspiration channel (3), induced draft fan (4), tunnel (5), it is characterized in that aspiration channel radially is installed in tunnel top; Induced draft fan is installed in the aspiration channel two ends; The inlet scoop is opened on the aspiration channel tube wall, and butterfly valve is installed in the adjacent position, inlet scoop, and the inlet scoop is whenever offered one at a distance from 50 meters.
The beneficial effect of the utility model is: the utility model can reduce the tunnel noise, reduces electric quantity consumption, improve drafting efficiency, and still can keep ventilation under the condition of a disaster such as stops up, catch fire in the tunnel roof fall.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
According to shown in Figure 1; Process the aspiration channel (3) of diameter more than 40 centimetres with iron sheet or refractory material; Radially connect and be installed on top, tunnel (5); Offer an inlet scoop (1) at a distance from 50 meters in that aspiration channel (3) tube wall is every, each inlet scoop disposes butterfly valve (2), and induced draft fan (4) is respectively installed at aspiration channel (3) two.
The inlet scoop (1) of aspiration channel (3) is used the local ventilation that can also realize certain section in the tunnel (5) with butterfly valve (2).Such as meeting fire in tunnel (5), just aspiration channel (3) before and after the burning point and butterfly valve (2) are closed, open butterfly valve (2) inlet scoop, outer end (1) suction combustion fumes, both guaranteed that tunnel ventilation, personnel breathed safety, can avoid air blast combustion-supporting again.
Claims (1)
1. novel tunnel ventilation installation; Constitute by inlet scoop (1), butterfly valve (2), aspiration channel (3), induced draft fan (4), tunnel (5); It is characterized in that aspiration channel (3) radially is installed in top, tunnel (5), induced draft fan (4) is installed in aspiration channel (3) two ends, and inlet scoop (1) is opened on aspiration channel (3) tube wall; Butterfly valve (2) is installed in adjacent position, inlet scoop (1), and inlet scoop (1) is whenever offered one at a distance from 50 meters.
