Title: CYCLONE HEAT EXCHANGER DEVICE
Abstract:
The present invention relates to a cyclone heat exchanger device, and provides a cyclone heat exchanger device comprising: a body in which exhaust gas including heavy metals and corrosive materials of a gas phase flows through an inlet pipe located at one side thereof; an outlet pipe located through an inside and outside part of an upper side of the body; an internal heat exchanger located inside the outlet pipe; and an injection unit located at an outer side of the outlet pipe so as to inject an addictive agent which neutralizes gas-phased corrosive materials included in the exhaust gas introduced from the body. According to the invention, the heat exchanger is located over the inside and the outside of the outlet pipe and thus can raise, through double heat exchange, the efficiency of heat recovery from exhaust gas, and heavy metals and corrosive materials included in the exhaust gas can be separated and eliminated to prevent corrosion of the heat exchanger. Therefore, the heat exchanger does not require an additional corrosion resistance process.
