Abstract
The invention provides an air duct design method used for natural wind energy conservation and utilization in a tunnel. As for an underground fan room, an air duct is blocked by fans arranged in the fan room when the fans are not opened. Therefore, an auxiliary air duct is added at the position of the air duct in the fan room and natural wind can enter the tunnel through an energy-saving air duct. When the direction of natural wind in a ventilation path in the tunnel is the same as the design direction, that is to say, q larger than q0, the energy-saving air duct is completely utilized for ventilation. When the direction of natural wind in a ventilation path is the same as the design direction, that is to say, 0 less than q less than q0, a part of fans and the energy-saving air duct can be opened for ventilation. When the direction of natural wind is opposite to the design direction, the fans are opened and proper power is adapted for ventilation. The air duct design method used for natural wind energy conservation and utilization in the tunnel has following beneficial effects: natural wind resources in the tunnel can be utilized effectively by the energy-saving air duct in order to make contribution to energy conservation and emission reductions in the later period of ventilation for the tunnel; and loss of mechanical ventilation in the tunnel is reduced.
Description
Technical field
The invention belongs to the natural wind method for designing field in pipeline tunnel, be specifically related to a kind of for tunnel
The Duct design method that natural wind energy-saving utilizes.
Background technology
Tunnel is more and more built along with existing major long tunnel, for reduction of erection time and ventilation requirement,
Up to tunnel often with one or more tiltedly (erecting) wells, and carry the stagewise of tiltedly (erecting) well longitudinally
Draft type, is also developing progressively the draft type used for the most most of long highway tunnels.
Basic diagram is as follows: major long tunnel, in order to realize the ventilation of segmentation Longitudinal, generally requires and is configured to
Descending or surface wind machine room, be provided with axial flow blower in Ventilator Room air channel, the unlatching of axial flow blower forms tunnel
Ventilation power in road.But show according to existing research, along with building now the length at weather dividing strip
Big tunnel gets more and more, and utilizes natural wind energy-saving to become a kind of trend, and three as shown in Figure 1
In individual ventilation section, each section all can form natural wind, at natural wind relatively under the driving of natural ventilation pressure
The when of big, tunnel can fully rely on natural wind and be aerated in the case of blower fan cuts out.So
And, with the design of existing underground Ventilator Room, the situation that the axial flow blower at underground Ventilator Room is not turned on
Lower natural wind just cannot pass through, it is clear that this wastes huge natural wind resource undoubtedly, is unfavorable for growing up
The reduction of the later stage operation energy consumption in tunnel, exacerbates the energy consumption such as ventilation during major long tunnel is runed due to the later stage
The awkward situation that excessive caused tunnel " afford to repair, can not afford ".
Summary of the invention
In order to solve defect of the prior art, the present invention provides one to make full use of natural wind, reduces
Force ventilation during permanent ventilation of tunnel is to reduce the sharp for tunnel natural wind energy-saving of ventilation energy consumption
Duct design method.
The present invention is achieved through the following technical solutions:
A kind of Duct design method utilized for tunnel natural wind energy-saving, for underground Ventilator Room, at wind
Owing to being provided with blower fan in machine room, in the case of blower fan is not turned on, air channel is intercepted by blower fan, because of
This needs to add auxiliary air channel, namely energy saving air duct in position, Ventilator Room air channel, to ensure at wind
In the case of office closes, natural wind can enter tunnel by energy saving air duct.
When the natural wind wind direction in tunnel ventilation path is identical with design wind direction, and natural wind air quantity is more than setting
Meter ventilation volume, i.e. q ＞ q0Time, fully utilized energy saving air duct is aerated；When natural wind wind direction with set
Meter wind direction is identical, and natural wind air quantity is more than design ventilation volume, i.e. 0 ＜ q ＜ q0Time, opening section blower fan
Work in coordination with energy saving air duct and be aerated；When natural wind wind direction is contrary with design wind direction, open blower fan, adjust
Whole to appropriate power, it is aerated.
The beneficial effects are mainly as follows the following aspects: a kind of for tunnel natural wind joint
The Duct design method that can utilize is so that energy saving air duct effectively make use of the nature in tunnel
Wind-resources, the energy-saving and emission-reduction for tunnel later stage operation ventilation are made that certain contribution, decrease tunnel
The energy consumption of force ventilation.

Detailed description of the invention
Below the preferred embodiment of the invention is illustrated.
A kind of Duct design method utilized for tunnel natural wind energy-saving, for underground Ventilator Room, at wind
Owing to being provided with blower fan in machine room, in the case of blower fan is not turned on, air channel is intercepted by blower fan, because of
This needs to add auxiliary air channel, namely energy saving air duct in position, Ventilator Room air channel, to ensure at wind
In the case of office closes, natural wind can enter tunnel by energy saving air duct.
Table 1 ventilation shaft Energy Saving Control strategy
When the natural wind wind direction in tunnel ventilation path is identical with design wind direction, and natural wind air quantity is more than setting
Meter ventilation volume, i.e. q ＞ q0Time, fully utilized energy saving air duct is aerated；When natural wind wind direction with set
Meter wind direction is identical, and natural wind air quantity is more than design ventilation volume, i.e. 0 ＜ q ＜ q0Time, opening section blower fan
Work in coordination with energy saving air duct and be aerated；When natural wind wind direction is contrary with design wind direction, open blower fan, adjust
Whole to appropriate power, it is aerated.
Although technical scheme has been done the most detailed elaboration and has enumerated by inventor, it should
Understand, to those skilled in the art, above-described embodiment is made amendment or uses equivalent
Replacement scheme, this be to those skilled in the art it is clear that without departing from the present invention spirit
