Abstract
An elevator shaft staggered gravity spraying and air feeding and exhausting device comprises spraying devices, vertical water supply pipes and air feeding and exhausting devices. The spraying devices are sequentially arranged on the two sides of the inner wall of an elevator shaft downwards oppositely from the fourth floor counted backwards of the elevator shaft. The vertical water supply pipes are connected with water supply pipes of the upper three floors of the floors where the spraying devices are located, so that the pressure difference exists between water supply pressure and water outflow pressure of the spraying devices, and automatic spraying is achieved. A water outflow line of the spraying devices is that the former spraying device sprays water to the latter spraying device, so that an oblique Z-shaped spraying water curtain is formed. The air feeding and exhausting devices correspond to the spraying devices one to one and the air feeding and exhausting devices are divided into air feeding pipes and air exhausting pipes. The air feeding pipes are arranged above the spraying devices and the portions, from the inner wall of the elevator shaft to openings of an outer wall, of the air feeding pipes are pipes inclining downwards. The air exhausting pipes are arranged below the spraying devices and the portions, from the inner wall of the elevator shaft to the openings of the outer wall, of the air exhausting pipes are pipes inclining upwards. Plenum fans are arranged at the portions, located in the openings of the outer wall, of the air feeding pipes. Exhaust fans are arranged at the portions, located in the openings of the outer wall, of the air exhausting pipes.
