Steam exhaust waste heat utilization system of steam powder machine

The invention relates to the technical field of waste heat utilization of titanium dioxide production systems, in particular to a steam powder machine exhaust steam waste heat utilization system which comprises a high-temperature bag filter, a demineralized water spray tower, an exhaust steam heat exchanger, a water seal tank, a three-washing water tank, a gas-water heat exchanger, a balanced reservoir, a variable-frequency water pump unit, a hot blast stove and circulating heat medium water. And an air inlet of the high-temperature bag filter is communicated with an air outlet pipe of the steam powder machine. The waste heat utilization efficiency of the dead steam of the steam powder machine can be improved, and the gas consumption of the hot-blast stove is reduced; the recovery and utilization efficiency of water resources can be improved, and the consumption of demineralized water in the demineralized water spraying tower is reduced; the air draft power consumption of the air outlet side of the spray towe
