Abstract
For tunnel ventilation, a plurality of blast fans of installing in the tunnel, they are used for the local air flow in the delivery tunnel.All or wherein a part of blast fan respectively be provided with the device that a local air flow that blast fan is carried is handled and/or filtered.
Description
The present invention relates to a kind of ventilating apparatus for tunnels, it have be contained in the tunnel and delivery tunnel in the blast fan of local air flow.
This kind equipment is preferably used in longitudinal ventilation, at this moment because the impulse action of blast fan is longitudinally flowed the air in the tunnel in the tunnel.So far this longitudinal ventilation only is widely used in the short tunnel.But or plan in long tunnel, to adopt longitudinal ventilation, at this moment at top, tunnel installing blast fan bigger, that be designed to the jetting type ventilator.Because the length in tunnel is longer, except that the jetting type ventilator, airshaft in the middle of also needing is so that can carry out the exchange of fresh air and waste gas by it.In addition, the also known horizontal or half horizontal ventilation equipment that are useful on tunnel ventilation.They are being used for also requiring to establish middle airshaft when long tunnel ventilates.
The objective of the invention is to design such equipment, and they also can fully ventilate when being used in the long tunnel even without the middle vertical shaft of outwards supplying gas.
By this kind equipment of the present invention measure of being adopted that achieves the above object be, all or wherein a part of blast fan respectively be provided with the device that a local air flow that blast fan is carried is handled and/or filtered.Utilize this device not only to cause longitudinal ventilation, and removed the harmful exhaust in the tunnel air, and in air, replenished necessary additive again.Therefore can cancel the exchange of carrying out fresh air and waste gas by middle airshaft.
Accompanying drawing has been represented various embodiments of the present invention, below they is further described.
Fig. 1 has the tunnel longitudinal plan of present device,
Fig. 2 has the tunnel longitudinal plan of the another kind of embodiment of the present invention,
Fig. 3 has the tunnel drawing in side sectional elevation of other embodiment of the present invention,
The IV of Fig. 4 Fig. 3-IV section.
Tunnel, 1 upper edge, 2 top, tunnel is vertically hanging some blast fans in a certain distance apart from one another, and they all are designed to jetting type ventilator 3.Jetting type ventilator 3 comprises an exhaust fan rotor 5 by motor 4 transmissions.Exhaust fan rotor 5 and motor 4 are contained in the housing 6, and housing 6 comprises an admission pipe 7 and a stack 8.
Each jetting type ventilator 3 sucks a part of tunnel air by the tunnel, and quickens vertically to discharge along the tunnel.Local air flow through quickening plays the work jet, and it is with the ambient air blending and make it to quicken towards the tunnel exit direction mobile.The air that these are longitudinally carried by impulse action is sucked in the same way by next longitudinal ventilation with jetblower device 3 and continues and carries.Also can be in a plane a plurality of longitudinal ventilation with jetblower devices 3 of parallel side by side installation, rather than only use one.
Establish strainer in the housing 6 of each or a part of longitudinal ventilation with jetblower device 3, it can be bag filter or electro-filter.As to the substituting or replenishing of strainer, can in housing 6, establish antigravity system or other general system, to be used for that some undesirable material such as carbon dioxide are carried out chemical reaction or physical change.The treatment system of fresh air, oxygen or other desired substance is housed in housing 6 in addition.Additive by in the tunnel 2 that is laid in and the conduit with smaller cross-sectional area send into.
By said apparatus, removed contained harmful exhaust in the air in tunnel 2, and replenished necessary additive.Therefore get rid of airborne nuisance, thereby reached the purpose of in the local finite scope of tunnel air, supplying the air that contains fresh material.
Vertical installation in represented longitudinal ventilation with jetblower device 3 suitable tunnels 2 among Fig. 2.Longitudinal ventilation with jetblower device 3 makes air flow along the diagram direction of arrow.At this moment purify the air that flows out, and added fresh material therein.
If do not utilize the impulse action of blast fan, so also can use with blast fan and be linked into as a whole filtration and treating apparatus.This information slip is shown among Fig. 3 and Fig. 4.Blast fan 11 be contained in the top 1 on and the end 9 under.Be equipped with opening 10 at the top 1 and the end 9.Shown in the arrow among the figure, formed horizontal ventilation.
Claims (1)
- Ventilating apparatus for tunnels, it has and is contained in the tunnel (1) and the blast fan (3,11) of delivery tunnel (1) internal gas flow, it is characterized by: all or wherein a part of blast fan (3,11) respectively be provided with the device that a local air flow that blast fan (3,11) is carried is handled and/or filtered.
