Problems solved by technology

In the HVAC ventilation and air-conditioning system of nuclear power plants, due to the large air volume and limited space, some ventilation ducts have small cross-sectional areas, and the filters arranged side by side lead to a reduction in the filtering area and thus reduce the air volume, which cannot meet the use requirements.

Abstract

The invention discloses an antiseismic prefilter framed bent in V-shaped arrangement. The antiseismic prefilter framed bent comprises a framed bent assembly, a rubber sealing element, a plate-type prefilter and a V-shaped pressing plate, wherein the framed bent assembly comprises a frame, a top bottom sealing plate fixedly welded at one side of the frame, a plurality of side sealing plates in V-shaped arrangement, a front sealing plate, a rear sealing plate and a middle clapboard, wherein the front ends of adjacent side sealing plates are welded with the front sealing plate, the rear ends of adjacent side sealing plates are welded with the rear sealing plate, the front ends of the first side sealing plate and the last side sealing plate are welded with the frame, the front sealing plate and the rear sealing plate are both welded with the top bottom sealing plate, and the middle clapboard is welded between adjacent side sealing plates; the frame is fixed on the wall, the rubber sealing element is arranged at the mounting parts of the frame and the wall, the plate-type prefilter is fixed on the frame bent assembly by the V-shaped pressing plate, and a sealing pad is arranged between the plate-type prefilter and the framed bent assembly. The antiseismic prefilter framed bent is convenient to install and dismount, safe and reliable, convenient to maintain, small in resistance, large in air volume, and suitable for ventilating ducts with small sectional area.

Description

technical field [0001] The invention relates to the technical field of ventilation and air conditioning systems used in nuclear power plants, in particular to an anti-seismic V-shaped pre-filter bent frame. Background technique [0002] The filter rack currently installed in the HVAC ventilation and air conditioning system of the nuclear power plant is used to filter the air. When the fan is running, the air passes through the pre-filter fixed on the rack and then enters the room with cleanliness requirements, so that the air has a certain degree of cleanliness to meet the environmental conditions for the operation of process equipment and the entry and exit of personnel. In the HVAC ventilation and air-conditioning system of nuclear power plants, due to the large air volume and limited space, some ventilation ducts have small cross-sectional areas, and the filters arranged side by side reduce the filtering area and reduce the air volume, which cannot meet the use requiremen...
