Abstract

The invention provides an integrated guide jet fan box. The integrated guide jet fan box comprises a jet fan module, silencer modules and flow guide modules. The jet fan module is located in the middle, the silencer modules are symmetrically connected to the two sides of the jet fan module, and the flow guide modules are connected to the silencer modules on the two sides respectively and are also symmetrically arranged relative to the jet fan module. According to the jet fan module, the silencer module and the flow guide module, profile steel frames independently form an appearance frame, stainless steel plates form an outer skin, a trapezoid box body is integrally formed, and a ventilation channel extending along the long bottom edge of a trapezoid is formed in the box body. A jet fan is arranged in the jet fan module, a silencer is arranged in the silencer module, and the end of the flow guide module is provided with a gradually-changed air opening. The problems that civil engineering reservation conditions are complex, and the construction period is long are solved.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation, in particular to a jet fan box that can be used in tunnel projects such as railways and urban rail transit. Background technique [0002] In recent years, with the large-scale construction of railway tunnel projects and urban rail transit projects, the disaster prevention, ventilation scheme design and equipment selection in the above engineering tunnels have been paid more and more attention. The jet fan is one of the most commonly used equipment in the tunnel disaster prevention and ventilation design of railway tunnel engineering and urban rail transit engineering. The conventional layout plan of the jet fan is to install the jet fan on the upper part of the tunnel side wall. Especially in rail transit tunnels, in order to reduce the tunnel section and avoid the conflict between the jet fan and the vehicle, generally excavation is carried out on the top or side wall of the tunnel to...
