Cyclone dust collector with water cooling function and working method

The invention relates to a cyclone dust collector with a water cooling function. The cyclone dust collector comprises an outer barrel, an inner barrel, an ash storage device, a steam box and a water cooling device, the invention further relates to a working method of the cyclone dust collector with the water cooling function. The dust collector has the beneficial effects that the inner side wall of the inner cylinder body continuously forms the set gradient from top to bottom, heat exchange between high-temperature dust-containing gas and cold water in the partition cavity is facilitated, the heat exchange place is the whole inner side wall of the inner cylinder body, the heat exchange surface area is large, and the heat exchange efficiency is high; the gradient of the inner side wall of the inner cylinder body is beneficial for dust particles in dust-containing gas to impact the inner side wall and settle into the dust storage device, so that the communication part of the inner cylinder body and the dust sto
