The invention discloses a heat exchange and dust removal integrated
cyclone dust removal device which comprises a shell, a spiral
pipe is arranged on the outer wall of the shell, a dusty gas inlet is formed in the upper portion of the shell and located above the spiral
pipe, a purified gas outlet is formed in the top of the shell, a water tank is arranged on the outer wall of the purified gas outlet, and a plurality of heat pipes are arranged in the water tank. An ash
discharge port is formed in the bottom of the shell. A heat exchange function is integrated in the
cyclone dust removal device, high-temperature dust-containing gas enters the shell to achieve
solid-
gas separation, meanwhile, the high-temperature gas flows in the shell at a high speed, heat is concentrated towards the
pipe wall under high-speed spiral motion, then heat exchange is conducted through the pipe wall and a heat exchange medium of the spiral pipe, a fluid flowing boundary layer is effectively thinned, and the heat exchange efficiency is improved. The
heat resistance is reduced, the heat exchange efficiency is improved, and the problem of
waste heat loss caused by separate treatment is avoided. And the heat of the
smoke can be transferred into the water tank through the
heat pipe, so that the heat exchange efficiency is further improved, and the waste of the heat is avoided.
