Rapid blocking and nuclear-grade ventilating and purifying treatment vehicle for tunnel

Abstract

The invention discloses a rapid blocking and nuclear-grade ventilating and purifying treatment vehicle for a tunnel. The rapid blocking and nuclear-grade ventilating and purifying treatment vehicle for the tunnel comprises a tunnel entrance rapid blocking system, an exhaust system, an air makeup system and an automatic detection and control system. The tunnel entrance rapid blocking system communicates with the exhaust system and the air makeup system through pipelines correspondingly. The automatic detection and control system is connected with the exhaust system through electric signals. The tunnel entrance rapid blocking system comprises a rapid inflation type air bag and an air compressor, wherein the rapid inflation type air bag is connected with the tunnel in a sealed mode. The exhaust system comprises an air suction port, a prefilter, a nuclear-grade high-efficiency filter, an exhaust fan and a rain-proof and snow-proof air exhaust port. The air makeup system comprises an air blasting port, a makeup machine and a rain-proof and snow-proof air suction port. The rapid blocking and nuclear-grade ventilating and purifying treatment vehicle for the tunnel is compact in structure and convenient to operate; rapid emergency nuclear pollution treatment can be achieved, the filter efficiency can reach 99.99% or over, atmospheric pollution is effectively prevented, and personal safety is guaranteed.

Description

technical field [0001] The invention belongs to a tunnel sealing and purification treatment device, in particular to a tunnel rapid closure and nuclear-level ventilation and purification treatment vehicle. Background technique [0002] With the continuous development of science and technology, tunnel sealing is an important scientific and technological problem. Due to the different cross-sectional areas of tunnels, some special tunnels have large cross-sectional areas, sometimes up to 100m 2 As mentioned above, when a nuclear leakage event occurs in a tunnel or culvert, methods such as concrete sealing wall, grouting water blocking, hanging net anchor shotcrete, local steel support reinforcement and other methods are usually used to seal it. However, these methods not only have a long construction period, but also It is difficult to quickly block the tunnel entrance, so that a large flow of air containing radioactive aerosols leaks, causing serious pollution to the atmospher...
