When the axial flow fan 1 continuously sucks air from the front end in the box body and discharges the air from the air outlet groove 35 to the lower end in the box body, the flowing air takes away heat generated by the electric heating pipe 2 due to the upward flowing of the air and acts on cotton gauze containing waste liquid through the air penetrating port on the surface of the partition plate 33, so that the waste liquid on the cotton gauze is evaporated by the hot air, the hot air containing the waste liquid enters the shell body 8 through the front end of the shell body 8, the waste liquid in the air is rapidly cooled into liquid under the cooling effect of the evaporator 41, the liquid of the waste liquid falls at the lower end in the shell body 8 due to the gravity effect of the liquid and is discharged into a waste liquid barrel from the front lower end of the liquid discharge pipe 81 (a waste liquid barrel is placed under the liquid discharge pipe in advance), the cooled air enters the air inlet pipe of the axial flow fan again and then enters the front end in the box body for circulation, and the process is continuously circulated, so that the waste liquid contained in the cotton gauze can be effectively and completely recovered, when the waste liquid is not discharged any more through the liquid discharge pipe 81, the waste liquid on the cotton gauze is completely recovered (generally about ten minutes). This novel ability waste liquid obtains recycle to saved the production side and sent the cost that relevant department handled and bring to such as cotton gauze that will contain the waste liquid, because in the box with external isolated, the air only in the box front end, axial fan and the evaporimeter of cooler and the equal circulation flow in the casing, consequently prevented that the waste liquid from discharging to causing environmental pollution in the atmosphere. The relay K is a DC12V relay, the temperature switch W is a finished product of the adjustable liquid expansion type temperature controller, and the temperature control range is 30-350 ℃.
