Abstract

The invention relates to the technical field of underground garage smoke prevention and exhaust, and discloses a multilayer underground garage vertical ventilation smoke prevention and exhaust system.The multilayer underground garage vertical ventilation smoke prevention and exhaust system comprises a smoke prevention system and a smoke exhaust system which are arranged in an escape staircase, wherein the smoke prevention system comprises a pressurizing fan, an air outlet pipeline and an air outlet which are sequentially connected, the smoke exhaust system comprises a plurality of air inletsformed in each layer of the garage and a plurality of air exhaust ducts and air exhaust outlets vertically arranged on the side walls of the garage, a closed calcium hydroxide solution pool is furtherarranged below the bottom layer of the garage, the upper ends of the air exhaust ducts are connected with the air exhaust outlets, the lower ends of the air exhaust ducts stretch into the position below the liquid level in the closed calcium hydroxide solution pool, and the air inlets are connected with the side surfaces of the exhaust ducts. The problems that an existing garage smoke preventionand exhaust system is single in a smoke exhaust mode, low in the utilization rate of the exhaust ducts, and cannot purify smoke are solved.

Description

technical field [0001] The invention relates to the technical field of smoke prevention and exhaust for underground garages, in particular to a vertical ventilation and smoke prevention system for multi-storey underground garages. Background technique [0002] With the rapid growth of the number of vehicles and the concentration of the population, in order to meet the parking spaces for vehicles, multi-storey underground garages form an indispensable supporting facility for many high-rise buildings. The more floors in the garage, the worse the ventilation, especially But now most of the vehicles are gasoline vehicles, each car will produce a lot of exhaust gas when it is parked and left in the garage, resulting in a lot of smoke in the garage, and it is not easy for these smoke to flow out of the garage automatically. [0003] Now, all underground garages are equipped with smoke prevention and exhaust systems. The so-called smoke prevention and exhaust systems are the genera...
