Description
Technical field
The utility model relates to the skyscraper smoke control system, and especially the skyscraper fume-resisting system of toilet pressure air blowing, belong to building ventilation smoke evacuation technical field.
Background technology
Along with the development of urban construction, skyscraper is more and more general, and the Smoke control system design of skyscraper is a very important content.According to statistics, in fire of high-rise building, the number of casualties is choked to death owing to being subject to fire smoke more than 70%, so the flue gas under the fire of high-rise building situation is controlled most important.About research and the design of skyscraper smoke control system, Chinese scholars has been carried out a large amount of and deep research.China's existing " Code for fire protection design of high rise buildings " (GB 50045-95) (hereinafter to be referred as " high rule ") regulation high-rise civil building fireproof natural draught system, mechanical smoke extraction and mechanical smoke prevention method and facility.Theory analysis according to flue gas control, after the building breaking out of fire, the control of discharging fume in the fire area, discharge rapidly flue gas and the heat that produces, non-fire area and fire escape are adopted rapidly the Smoke prevention measure of mechanical pressure air blowing, making this regional air pressure is relative malleation, stops the intrusion of flue gas.High-rise civil building adopts mechanical pressure air blowing mode to mainly contain following three kinds: only to stairwell pressurization air-supply, smoke proof staircase with share cup simultaneously pressure air blowing, only face toward the fire bed vestibule pressurization.At present, when staircase only connected the staircase cup, various countries reached common understanding, can be only to the stairwell pressurization air-supply, and cup does not arrange independent compression system; When cup was share in the staircase connection, China's new " high rule " stipulated staircase and share cup and pressurize respectively.
How above skyscraper smoke-discharging proof method all controls flowing of flue gas based on occuring after building fire basically, how creates conditions for evacuating personnel.But fire development to a certain extent after, personnel find that fire is more late or for action inconvenient personnel, as old, children and patient, evacuation may face larger danger, does not possess the condition of safe escape.If to the toilet pressure air blowing, create certain safe space for indicator of trapped personnel this moment, wait for rescue, can improve the probability of surviving of trapped personnel in building fire.After building fire occurs, by contrast, that the above floor of fire bed is easier is invaded by flue gas, personnel are dangerous large.Studies show that, 95% flue gas spreads by architectural shaft and enlarges fire, and is provided with the pressure air blowing device between architectural stair, so lift well becomes the main thoroughfare that flue gas vertically spreads.By floor toilet pressure air blowing, especially the above floor of fire bed, can improve floor area pressure, stop flue gas to be invaded, can improve upper floor personnel's security.In high-rise civil building, windowless toilet is more common a kind of form, and its air draft mainly contains dual mode: mechanical exhaust combines with natural exhaust, mechanical exhaust.Mechanical exhaust combines with natural exhaust and refers to that each toilet all establishes one with the toilet ventilator of check-valves, between toilet ventilator and exhaust air shaft, fire resisting damper is set, and does not establish concentrated exhaust blower.This mode generally is used for ordinary residence and the not high building of hygienic requirements.Mechanical exhaust divides dual mode: toilet ventilator is not established in (1) each toilet, only establishes air draft, requires exhaust blower to bear the exhaust air rate of all toilets, and this mode is mainly used in the communal bathroom of high-rise.(2) each toilet is all established one with the toilet ventilator of check-valves, foul atmosphere and the steam of toilet are drained in horizontal or vertical main air duct, drained into outdoorly by the exhaust blower of being located at total air channel end or top, this mode is widely used in the high high-rise of hygienic requirements again.
The utility model content
The purpose of this utility model is to provide the skyscraper fume-resisting system of a kind of toilet pressure air blowing, be the toilet air draft under this system's normal condition, when building fire occurs after, to the toilet pressure air blowing, for indicator of trapped personnel provides interim fire area, can improve to a certain extent the survival rate of trapped personnel in building fire.
Problem described in the utility model realizes with following technical proposals:
the skyscraper fume-resisting system of a kind of toilet pressure air blowing, special feature is, it comprises roof ventilator, air shaft, ventilation shaft and the toilet ventilator that is arranged in each resident family toilet, fire-preventino regulating valve, normally closed pressure air blowing mouth, described each toilet ventilator is communicated with air shaft through fire-preventino regulating valve, air shaft is communicated with ventilation shaft, described roof ventilator is arranged on the ventilation shaft place, the fans entrance valve is installed in the import of roof ventilator, at the porch of fans entrance valve and the exit air-supply in parallel by-pass line of roof ventilator, the air-supply by-pass line is provided with the pressure air blowing valve, be provided with the air intake bypass between fans entrance valve and roof ventilator, the air intake bypass is provided with the fans entrance by-passing valve.
The skyscraper fume-resisting system of above-mentioned toilet pressure air blowing, described roof ventilator are Double Speed Fan.
The skyscraper fume-resisting system of above-mentioned toilet pressure air blowing, described toilet ventilator is with check-valves.
The skyscraper fume-resisting system of above-mentioned toilet pressure air blowing, described roof ventilator and toilet ventilator are chain.
The skyscraper fume-resisting system of above-mentioned toilet pressure air blowing, described normally closed pressure air blowing mouth is opened by the fire protection control center Long-distance Control, or manually opened on the spot.
The utility model is trapped personnel existence probability problem when improving fire of high-rise building, has proposed the skyscraper fume-resisting system of a kind of toilet pressure air blowing.Described system is not in the situation that affect the normal air draft in toilet, set up normally closed pressure air blowing mouth in the toilet, roof ventilator adopts Double Speed Fan, and set up the air-supply by-pass line, described Double Speed Fan is in daily low speed air draft, keep the blowdown ventilation of toilet, when high-rise building with fire disaster be the floor high speed pressure air blowing more than fire bed, create certain safe space in the toilet, to the indicator of trapped personnel of failing in time to evacuate, can enter the toilet and temporarily take refuge, wait for rescue, greatly improve the survival rate of indicator of trapped personnel.Described systematic building cost is low, easy to implement, and it both had been applicable to tall buildings, also is applicable to the transformation of old building exhaust system.
