[0017] Specifically, the auxiliary mechanism 4 includes: a groove tube 401, a protrusion 402, a sponge strip 403, a pressing block 404, a frame 405 and an iron mesh 406;

[0018] The slot tube 401 is fixedly arranged at equal intervals inside the discharge pipe 3, and the slot tube 401 is used to support the sponge strip 403. The protrusion 402 is fixedly arranged at the bottom end of the slot tube 401, and the shape of the protrusion 402 is trapezoidal. The sponge strip 403 is fixedly arranged at the bottom end of the slot tube 401. The pressing block 404 is arranged at the top end of the slot tube 401, and the bottom end of the pressing block 404 is connected to the other end of the sponge strip 403. The pressing block 404 can squeeze the sponge strip 403 when it moves downward inside the slot tube 401. The frame 405 is fixedly arranged on the inner side of the pressing block 404, and the iron mesh 406 is fixedly arranged inside the frame 405. After the steam enters the interior of the slot tube 401 through the protrusion 402, the moisture contained in the steam is adsorbed by the sponge strip 403. Through grooves are provided on both sides of the slot tube 401, and a plurality of through holes are provided at the bottom end of the slot tube 401. The material of the sponge strip 403 is rubber sponge.

[0019] More specifically, the pulling mechanism 5 includes: an electric push rod 501, a connecting frame 502 and a cross bar 503;

[0020] The electric push rod 501 is set on the left outer wall of the discharge pipe 3. The electric push rod 501 can drive the pressure block 404 to move downward through the cross bar 503. The connecting frame 502 is fixedly set on the outer wall of the electric push rod 501, and the right side of the connecting frame 502 is connected to the outer wall of the discharge pipe 3.

[0021] Working principle: When the composite evaporator for formaldehyde production is put into use, when the internal pipeline of evaporator 1 is heated to a certain temperature, the water at the bottom of evaporator 1 is transported to the top of evaporator 1 through circulating pump 2 and sprayed out to cool the pipeline. The steam generated during the cooling process is discharged through discharge pipe 3. When the steam moves upward inside the discharge pipe 3, part of the steam will pass through the protrusion 402 and enter the inside of the groove pipe 401. Then, when the steam passes through the inside of the groove pipe 401, the moisture attached to the steam will be absorbed by the sponge strip 403, and then the adsorbed steam will be discharged from the top of the groove pipe 401. The steam that has not entered the groove pipe 401 will also attach a small amount of moisture to the surface of the iron mesh 406 when passing through the iron mesh 406. When the moisture inside the sponge strip 403 is absorbed to After a certain degree, the user can control the electric push rod 501 to move downward through the external control unit. When moving, the cross bar 503 drives the pressure block 404 to move downward at the same time and move to the inside of the groove tube 401, and then the frame 405 drives the surrounding pressure blocks 404 to move downward at the same time. When the pressure block 404 continues to move downward inside the groove tube 401, it will squeeze the sponge bar 403. The squeezed sponge bar 403 squeezes out the water inside, and then the water squeezed out of the sponge bar 403 will be discharged from the through hole at the bottom end of the groove tube 401 and the through grooves on both sides and fall downward. The fallen water will fall into the water reservoir at the bottom end of the evaporator 1 for utilization. The user can pull the electric push rod 501 downward according to the time when the sponge bar 403 is full of water.
