A smog adsorption and purification vehicle, comprising a base plate (1), a gas intake apparatus (2), a first filtration apparatus (3), a spraying apparatus (4), a cleaning apparatus (5), a pushing apparatus (6), an exhaust apparatus (7), and a fixing apparatus (8). A first roller (11) is provided on the base plate (1). The gas intake apparatus (2) comprises a gas intake pipe (21), a first fan (22), a first conduit (23), a first filter (24), a second filter (25), a first support frame (26), a second support frame (27), a third support frame (28), and a first sponge block (29). The first filtration apparatus (3) comprises a first purification frame (31), a second conduit (32), a third filter (33), a first support rod (34), a fourth filter (35), an adhesive frame (36), an adhesive block (37), a first horizontal rod (38), a third conduit (39), and a second support rod (30). The spraying apparatus (4) comprises a spraying frame (41), a first stopping block (42), a first stopping ring (43), a first triangular block (44), a water outlet pipe (45), a fourth conduit (46), a fourth support frame (47), a water inlet pipe (48), and a first water tank (49). The cleaning apparatus (5) comprises a cleaning frame (51), a third support rod (52), a fourth support rod (53), a second sponge block (54), a first rotating shaft (55), and a fist motor (56). The present smog absorption and purification vehicle effectively filters smog and prevents dust from accumulating on the filters, thus increasing filtration efficiency.
