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

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.
