Through setting up connecting device, realized the circulation flow of solution in dust collector, dehydrating unit to great saving the energy. The solutions flowing out of the first solution output 7 and the second solution output 8 are pumped into the double pipe heat exchanger 26 by the solution pump 43. In the double pipe heat exchanger 26, the solution exchanges heat with the high temperature liquid flowing through the double pipe heat exchanger 26, so that the solution evaporates a part of the gas and raises the temperature.
