The invention relates to an urban air purifying vehicle capable of being normally used in
cold winter. A power cabin, a
liquid storage box and long-range mist-spraying dust-removal air purifying equipment are mounted on an automobile
chassis; an
electrical control box, a high-pressure liquid pump and a hydraulic
station are mounted at the lower part of the automobile
chassis; roller
shutter doors are respectively arranged on the front surface, the left surface and the right surface of the power cabin, the roof of the power cabin is an operable hard roof, and dustproof heat dissipating holes are formed in the rear surface near the top of the power cabin; a plurality of stainless steel heating pipes are longitudinally arranged in the
liquid storage box, the front parts of the stainless steel heating pipes are connected with automobile exhaust pipes, the rear parts of the stainless steel heating pipes go through the lower part of the
liquid storage box, two-position three-way valves are arranged at the connecting positions of the stainless steel heating pipes and the automobile exhaust pipes, a high-grade
antiseptic antirust
coating is coated on the inner part of a box body, and the liquid storage box is provided with a liquidometer and a
thermometer; the circuit of the
electrical control box is connected with the circuit of a
diesel generator group and the circuit of the long-range mist-spraying dust-removal air purifying equipment respectively; the high-pressure liquid pump is a stainless steel liquid pump, a liquid inlet of the high-pressure liquid pump is connected with the liquid storage box through a pipeline, and a liquid outlet of the high-pressure liquid pump is connected with a water spraying ring and an atomizing spray head through pipelines.
