The invention discloses a hot-dip galvanizing zinc smoke treatment process and system. The hot-dip galvanizing zinc smoke treatment process disclosed by the invention comprises the following steps of: blowing zinc smoke generated by a zinc pot at one end of the zinc pot, sucking and collecting the zinc smoke generated by the zinc pot at the other end of the zinc pot, then sending the sucked and collected zinc smoke into a sprinkling purifying tower and discharging the zinc smoke after the zinc smoke is washed and purified by sprinkling water in the sprinkling purifying tower. The hot-dip galvanizing zinc smoke treatment system disclosed by the invention comprises the sprinkling purifying tower, an induced draft fan, an air blower, an air blowing nozzle, a gas collecting hood and an exhaust chimney, wherein the air blowing nozzle is arranged at one end of the zinc pot, the gas collecting hood is arranged at the other end of the zinc pot and opposite to the air blowing nozzle, the air blower is communicated with the air blowing nozzle, the gas collecting hood is communicated with the sprinkling purifying tower through the induced draft fan, and the sprinkling purifying tower is communicated with the exhaust chimney. According to the hot-dip galvanizing zinc smoke treatment process and system provided by the invention, the zinc smoke generated by the zinc pot is collected in a longitudinal blowing and suction way, the zinc smoke generated by the zinc pot can be effectively collected, the power of the air blower is smaller, the procurement cost of equipment and the operation energy consumption are lower, and the zinc galvanizing operation cannot be affected.
