Claim 0:
1. A gas cooling-scrubbing apparatus, comprising, in sequence of gas flow: a cyclone jet scrubbing unit, a spray scrubbing unit, a filtering spray unit and a coalescing dehydration unit,
wherein the cyclone jet scrubbing unit comprises at least one cyclone jet scrubbing monopipe, a cyclone jet cooling water pipe, a cyclone jet pipe plate and a cyclone jet overflow pipe,
wherein the cyclone jet scrubbing monopipe includes a jetting region and a cyclone region, wherein the jetting region is provided with, in sequence, a cyclone jet inlet for receiving gas, a nozzle for spraying water into the gas, a contraction section, a mixing section, and an diffuser section, and wherein the cyclone region of the cyclone jet scrubbing monopipe is provided with a tangential inlet, a cyclone pipe, a sedimentation outlet near the bottom of the cyclone pipe, a cyclone jet pipe and a bubble cap for discharging gas from the cyclone jet scrubbing monopipe;
wherein the spray scrubbing unit is configured to receive gas discharged from the cyclone jet scrubbing monopipe, wherein the spray scrubbing unit comprises a spray filtering pipe, a spray pipe plate, a spray overflow pipe, a scrubbing nozzle oriented to discharge water into the upper portion of the spray filtering pipe, and a scrubbing nozzle water pipe,
wherein the spray filtering pipe comprises a spray inlet for receiving gas from the cyclone jet scrubbing monopipe, a spray port for discharging gas, and an internal filtering module located inside the spray filtering pipe between the spray inlet and spray port for filtering the gas moving through the spray filtering pipe;
wherein the filtering spray unit comprises a filtering bed, a spray head disposed above the filtering bed and a spray water pipe; and
wherein the coalescing dehydration unit comprises a coalescing bed, and wherein the coalescing bed is located below a gas phase outlet of the gas cooling-scrubbing apparatus.
