Problems solved by technology

[0003] One way to deal with it is to select the corresponding exhaust (smoke) fan and exhaust the smoke through the exhaust (smoke) pipe installed on the top of the platform rail area. In this way, the cross-sectional area of ​​the exhaust (smoke) pipe is very large, and the entire platform of the station needs to be exhausted. It is difficult to maintain the exhaust (smoke) pipe on the top of the catenary in the track area, and the aging of the air pipe will bring safety hazards after several years

Abstract

The invention relates to the field of rail transportation ventilation and fire control, and in particular to an open-closed system station subway platform ventilation and smoke exhaust method which is characterized in that: the smoke exhaust method is characterized in that: a smoke exhaust pipe is connected outside an air supply pipe, the air supply pipe is communicated with a small air exhaust chamber through the smoke exhaust pipe, a control valve is arranged on the joint of the smoke exhaust pipe and the small air exhaust chamber, when a station is in a fire accident, a control valve between the air supply pipe and an air supply chamber is closed, the control valve between the smoke exhaust pipe and the small air exhaust chamber is opened, a control valve of a centralized air return opening on the side wall of the small air exhaust chamber is closed, and an air supply opening on the air supply pipe, the smoke exhaust pipe and an air exhauster are used for exhausting smoke. Because the air (smoke) exhauster of the station is used for uniformly exhausting smoke through the air supply pipe of the platform, the smoke exhausting requirements of the platform are met. The method can be applied to the situation that the existing station is reconstructed, the height of the floors of the station is restricted, and the air (smoke) exhaust pipe in the rail area can not be arranged.

Description

technical field [0001] The invention relates to rail transit ventilation and fire protection, in particular to a ventilation and smoke exhausting method for an open and closed system station subway platform. Background technique [0002] When the underground rail transit station adopts the open and closed system, the ventilation (air conditioning) system is responsible for the ventilation (air conditioning) and smoke exhaust of the station at the same time. [0003] One way to deal with it is to select the corresponding exhaust (smoke) fan and exhaust the smoke through the exhaust (smoke) pipe on the top of the platform rail area. In this way, the cross-sectional area of ​​the exhaust (smoke) pipe is very large, and the entire platform of the station needs to be exhausted. It is difficult to maintain the exhaust (smoke) pipe located on the top of the catenary in the rail area, and the aging of the air pipe after several years will bring safety hazards. [0004] In subway st...
