The invention relates to the technical field of tunnel ventilation and discloses a tunnel ventilation system. The tunnel ventilation system comprises a tunnel ventilation device, and the tunnel ventilation device comprises an air inlet device and an air outlet device, wherein the air outlet device comprises a shell, a filtering plate above the shell and a fan above the filtering plate; the air outlet device comprises a bottom plate, a top plate connected with the bottom plate and an arc plate connected with the top plate; the bottom plate, the top plate and the arc plate define a cavity for ventilation; and the shell is communicated with the cavity. Compared with the traditional mechanical ventilation mode, the tunnel ventilation system obviously improves the ventilation effect, increases the safety factor, reduces noise pollution, saves energy and is environmentally-friendly.
Description
Technical field
The present invention relates to the tunnel ventilation technical field, related in particular to a kind of tunnel ventilation system.
Background technology
Good air conditions is the necessary condition of traffic safety in the traffic tunnel, and ventilation is for the concentration of pernicious gas in the tunnel or pollutant being reduced, guaranteeing running safety and comfortableness.
The common draft type of existing tunnel has following several:
Natural ventilation: so-called natural ventilation is meant to be got rid of pernicious gas and flue dust by 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, by the decontaminate mode of air of another hole.This mode, air pollution degree is linear by inlet to Way out to be increased, entrance pollution concentration minimum, it is big to survey pollution concentration in the outlet.Meet fire situation and can cause exporting place, hole concentration height, 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
The present invention is directed to traffic tunnel in the prior art and adopt the draft type of powerful mechanization air supply pattern, cause that energy consumption is big, noise pollution is serious, the halfway shortcoming of blowdown in the tunnel, provide that a kind of ventilation effect is remarkable, safety factor is high, noise pollution is few, the tunnel ventilation system of energy-conserving and environment-protective.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
The tunnel ventilation system, comprise the tunnel ventilation device that is arranged on the tunnel inwall, the tunnel ventilation device comprises air-intake device and goes out wind apparatus, air-intake device comprises housing, is arranged on the filter of housing top and the blower fan that is arranged on the filter top, go out wind apparatus and comprise base plate, the top board that links to each other with base plate and the arc that links to each other with top board, base plate, top board and arc surround a cavity that is used to ventilate, and described housing is communicated with cavity.
As preferably, described base plate comprises side plate, the transverse slat that links to each other with side plate and the bent plate that links to each other with transverse slat, side plate links to each other with top board, the upper end of described arc is connected with top board, the lower end is bending in cavity, and dogleg section stretches in the cavity, leaves the space between dogleg section and the bent plate lower end, air outlet forms Koln and reaches curved surface, makes that the fresh breeze effect is more remarkable.
As preferably, be evenly equipped with through hole on the described filter, filter can be used for filtering most grit, and by in the through hole suction ventilation cavity, air-flow forms an eddy current air channel and outside air chimney drains into the tunnel to the blade rotation of blower fan in ventilation housing with the contaminated air that produces in the tunnel.
As preferably, described housing is a cylindricality, and inside is hollow, guarantees that the inlet channel air inlet is unimpeded.
The present invention has significant technique effect owing to adopted above technical scheme:
There has been significant raising in this tunnel ventilation system than traditional mechanization air vent mode ventilation effect, has improved safety factor, has reduced noise pollution, energy-conserving and environment-protective.
