Problems solved by technology

[0023] From the above analysis, it can be seen that the first method cannot always ensure that the dynamic pressure drop between the holes on both sides is equal to the pressure loss between the holes on both sides, and the outflow angle is also unstable, which cannot satisfy the conditions (1) and ( 3); No matter how good the designer is, in a fixed system, it cannot guarantee that the ratio of the air flow out of the ori

Abstract

The invention discloses an intelligent uniform air supply device and method. The intelligent uniform air supply device comprises an air supply pipeline and adjustable air stop devices arranged in theair supply pipeline. The air supply pipeline is provided with a plurality of air outlets, and the adjustable air stop devices are arranged at the air outlets and are adjustable in angle. At least oneof the air outlets is provided with an anemometer, and the anemometer and the adjustable air stop devices are connected with a controller. The controller controls the angles of the adjustable air stopdevices according to the collected air speed and the air speed set value so that uniform air supply can be achieved.

Description

technical field [0001] The invention relates to an intelligent uniform air supply device and method. Background technique [0002] At present, there are two commonly used air supply methods in large underground station systems in the subway industry. figure 1 And attached figure 2 . attached figure 1 The air outlet is directly installed on the air supply main pipe, and the attached figure 2 The air outlet is installed at the short pipe port. [0003] See attached image 3 , when the air flows in the duct, its static pressure acts vertically on the duct wall. If a hole is made on the side wall of the air duct, due to the static pressure difference inside and outside the orifice, the air will flow out from the orifice in a direction perpendicular to the pipe wall. The flow rate due to the static pressure difference is: [0004] [0005] The velocity of air in the duct is: [0006] [0007] In the formula: [0008] p j is the static pressure of the air in the...
