Technical field
The utility model relates to a kind of ventilation installation, and particularly a kind of solar energy heating drives tunnel ventilation device.
Background technology
Along with the develop rapidly of China's speedway, the tunnel that mountainous area highway is large is also being on the increase.Large length of tunnel is long, and its cost of business operation, as electricity charge such as ventilation, illuminations, becomes the heavy burden of a lot of units of operation gradually.Suppose to consider to ventilate according to bidirectional tunnel, average every kilometer of tunnel approximately need arrange 6 jet blowers, every jet blower power is according to 30 kilowatts of considerations, every day ventilation time approximately eight hours, monthly only ventilate approximately 800,000 yuan of the electricity charge of this consumption of every kilometer of tunnel in prediction on such basis.According to incompletely statistics, the tens thousand of kilometers of the built highway tunnel being open to traffic of China at present, the energy-saving and cost-reducing problem of highway tunnel operation process seems particularly outstanding.
It is all to adopt jet blower to carry out forced ventilation to tunnel substantially that existing tunnel ventilates, tunnel adopts jet blower to ventilate in the time of tunnel breaking out of fire, jet blower is in " shut " mode", flue dust fills the air escape and rescue is brought to difficulty, if unlatching jet blower, jet blower can blow to the flue dust of point of origin the direction of not breaking out of fire, make to be full of in tunnel flue dust and even fire spreading, personnel escape and rescue are caused to very big difficulty and harm, and fire very easily burns out the cable of jet blower, cause jet blower power failure, affect the ventilation in tunnel.Therefore, one can be tackled tunnel special circumstances, guarantees that the proposition of the tunnel ventilation technology of tunnel operation security seems very urgent and necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of solar energy heating to drive heating tunnel ventilation device, the heat energy that it can absorb solar radiation adds hot air, makes tunnel inner air flow by the principle that hot gas rises, thereby realizes ventilation to tunnel, energy-saving and cost-reducing, safe and reliable.
For achieving the above object, the utility model is achieved by the following technical solutions.
A kind of solar energy heating drives tunnel ventilation device, it is characterized in that, comprise the base of multiple bar shapeds, be fixed on the transparent pipe of the multiple perforations on base, be communicated with the upper connecting box of multiple transparent pipes upper end simultaneously, be communicated with the lower connecting box of multiple transparent pipes lower end simultaneously, be communicated with the tunnel ventilation pipe of lower connecting box, pass into the hot-fluid guide pipe of connecting box, the hot-fluid chimney being communicated with the hot-fluid guide pipe other end; The inner lunette near below of described transparent pipe is coated with heat-sink shell, and below, described transparent pipe outside is glued with reservoir.
Feature of the present utility model and further improvement are:
Described each base is provided with multiple anchor ears and the tube connector of proper alignment, and the each anchor ear correspondence on base is fixed a transparent pipe;
The base of described fixing transparent pipe is arranged on the hillside tailo face outside tunnel.
Described upper connecting box on horizontal level higher than lower connecting box, the interface that described hot-fluid chimney connects hot-fluid guide pipe on horizontal level higher than on connecting box.
Described reservoir radially wraps up the height of transparent pipe from below is its diameter 1/3rd to 1/2nd.
Described reservoir is respectively mixed layer and the sandy gravel stratum of coal dust and improvement clay from top to bottom.
The beneficial effects of the utility model are, the transparent pipe that uses inner below to be equipped with heat-absorbing material receives sunlight as heating clamber, with lower connecting box and upper connecting box, multiple transparent pipes are communicated with to get up side by side again, increase air heat amount, lower connecting box and upper connecting box are communicated with respectively tunnel ventilation pipe and hot-fluid guide pipe, hot-fluid guide pipe passes into hot-fluid chimney, constantly by heated Bas Discharged in transparent pipe.The air-flow rising after heating makes transparent pipe and the lasting negative pressuren zone of the inner formation of upper and lower connecting box, negative pressuren zone constantly drinks up the air in tunnel, the air drinking up in tunnel is constantly discharged from hot-fluid chimney being heated, and having reached is the effect of tunnel internal circulation of air.Meanwhile, the reservoir that lay transparent pipe bottom also can store the heat that absorb daytime, to continue at night heating transparent pipe.Solar energy tunnel ventilation equipment of the present utility model are simple in structure, safe and reliable, and save the energy, reduced tunnel maintenance expense.
