Abstract

The invention relates to the technical field of electric appliance cabinets, and discloses a positive pressure type analysis room air inlet and silencing device. The device comprises a silencing structure, wherein the silencing structure comprises a direct exhaust pipe, a silencing layer and an exhaust pipe protection layer, air holes are evenly distributed in the pipe wall of the direct exhaust pipe, the silencing layer is breathable and covers the air holes, the exhaust pipe protection layer is arranged on the outer side of the silencing layer in a sleeving mode, and an exhaust channel is formed between the exhaust pipe protection layer and the silencing layer. According to the device, compressed gas in the direct exhaust pipe is diffused in the silencing layer through the air holes andis exhausted under pressure reduction, the exhaust pipe protection layer protects the silencing layer from being damaged, and compressed gas is uniformly diffused in a positive pressure room after passing through the silencing layer.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to a positive-pressure type analysis room inlet noise reduction device. Background technique [0002] In the field of petrochemical production, some precision instruments or power distribution equipment need to use a positive pressure room or building for isolation and explosion protection. The positive pressure room needs to be filled with protective gas so that the internal pressure is higher than the external atmospheric pressure to prevent the gas from invading the room, avoiding the isolation of electrical equipment that may become an ignition source from explosive gas, and protecting electrical equipment. [0003] In this kind of positive pressure room, it is necessary to install a protective gas intake device. The conventional method is to compress the fresh air duct into the positive pressure room through a fan in a safe area to achieve the purpose of filling the...
