[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 A tunnel drying and condensing cellulose production wastewater treatment equipment includes a wastewater collection box 1, which is used to hold cellulose organic wastewater. An evaporative wastewater component 2 is arranged on the periphery of the wastewater collection box 1. The evaporative wastewater component 2 includes a plurality of wastewater tanks 201 fixedly connected to the outer wall of the wastewater collection box 1. The wastewater tanks 201 are connected to the wastewater collection box 1. Two square water tanks 202 are arranged below the wastewater collection box 1. The wastewater collection box 1 is fixedly installed on the top of one of the square water tanks 202. A plurality of U-shaped water guide boxes 203 are fixedly connected between the two square water tanks 202. The wastewater tank 201 is located on the top of the U-shaped water guide box 203. An electric heating rod 204 is plugged into one of the square water tanks 202.

[0025] The water in the square water tank 202 is heated by the electric heating rod 204. The square water tank 202 is connected to the U-shaped water guide box 203. Therefore, when the water is heated to form water vapor, the U-shaped water guide box 203 will heat the wastewater in the wastewater tank 201. The wastewater concentration box 1 transmits the cellulose organic wastewater to multiple wastewater tanks 201, so that the water vapor in the U-shaped water guide box 203 can heat the wastewater in the wastewater tank 201.

[0026] During the heating process, the water in the wastewater gradually evaporates, thereby concentrating the organic matter and salts in the wastewater. As the water continues to evaporate, the solute concentration in the wastewater gradually increases. When it reaches saturation, the solute will precipitate in the form of crystals.

[0027] When the cellulose organic wastewater is heated to form water vapor, the water vapor formed by the cellulose organic wastewater can be condensed into crystals, and then the crystals can be collected to facilitate the next operation. The cellulose organic wastewater can be heated by heating the water through the electric heating rod 204, thereby reducing costs. Even if the electric heating rod 204 is damaged, it only needs to be replaced with a new one.

[0028] See also Figure 1A V-shaped air collecting hood 4 is fixedly installed on the top of the U-shaped water guide box 203. Multiple U-shaped water guide boxes 203 and the wastewater tank 201 are located inside the V-shaped air collecting hood 4. The V-shaped air collecting hood 4 is fixedly connected with a ventilation pipe 5. The ventilation pipe 5 is connected to the V-shaped air collecting hood 4, and a condenser is arranged inside the ventilation pipe 5.

[0029] The V-shaped air collecting hood 4 covers the steam generated by the cellulosic organic wastewater in the wastewater tank 201 to prevent the steam from leaking out, and then the steam is discharged to the next process through the ventilation pipe 5. A condenser is provided in the ventilation pipe 5. When the steam contacts the condenser, the water vapor will condense into water, thereby realizing the recovery and utilization of the steam. The solutes in the concentrated wastewater, such as cellulose salts, may form crystals after reaching saturation. These crystals can be further processed to realize the recovery and utilization of resources.

[0030] See also Figure 3 A filter plate 3 is fixedly mounted on the inner wall of the U-shaped water guide box 203 , and the bottom of the waste water tank 201 abuts against the filter plate 3 .

[0031] The filter plate 3 allows the water vapor in the U-shaped water guide box 203 to be emitted from the pores of the filter plate 3 , so that the water vapor in the U-shaped water guide box 203 can heat the cellulose wastewater in the wastewater tank 201 .

[0032] See also Figure 2 and Figure 4 The wastewater collection tank 1 is provided with a plurality of through slots 8 , the wastewater tank 201 is connected with the through slots 8 , the square water tank 202 is provided with a plurality of square slots 9 , and the U-shaped water guide box 203 is connected with the square slots 9 .

[0033] The wastewater collection box 1 is provided with a through slot 8 to facilitate the cellulose organic wastewater in the wastewater collection box 1 to enter the wastewater box 201 through the through slot 8, and the square water tank 202 is provided with a square slot 9 to facilitate hot water to enter the multiple U-shaped water guide boxes 203.

[0034] Embodiment 2:

[0035] See also Figure 2 and Figure 4 The inner wall of one square water tank 202 is rotatably connected to a connecting rod 10, and a plurality of fan blades 11 are fixedly installed on the outer wall of the connecting rod 10. A servo motor 12 is provided on one side of the square water tank 202, and the driving end of the servo motor 12 is connected to one end of the connecting rod 10. A solar panel 6 is fixedly installed on the outer wall of the V-shaped air collecting hood 4, and a battery 7 electrically connected to the servo motor 12 is fixedly installed on the outer wall of the V-shaped air collecting hood 4.

[0036] When the solar panel 6 is exposed to the sun, it converts light energy into electrical energy. The battery 7 is used to store this electrical energy, and then the electricity in the battery 7 is used to start the servo motor 12. The servo motor 12 drives the connecting rod 10 to rotate. When the connecting rod 10 rotates, it drives multiple fan blades 11 to rotate. The rotating fan blades 11 can accelerate the circulation of water in the square water tank 202, making the water heated more evenly, which is convenient for heating the cellulosic organic wastewater in the wastewater tank 201.

[0037] See also Figure 1 and Figure 4 A fixing plate 13 is fixedly installed on the outer wall of one of the square water tanks 202 , a servo motor 12 is installed on the top of the fixing plate 13 , a motor fixing belt 14 is fixedly installed on the top of the fixing plate 13 , and the servo motor 12 is located inside the motor fixing belt 14 .

[0039] Working principle:

[0040] The water in the square water tank 202 is heated by the electric heating rod 204. The square water tank 202 is connected to the U-shaped water guide box 203. Therefore, when the water is heated to form water vapor, the U-shaped water guide box 203 will heat the wastewater in the wastewater tank 201. The wastewater concentration box 1 transmits the cellulose organic wastewater to multiple wastewater tanks 201, so that the water vapor in the U-shaped water guide box 203 can heat the wastewater in the wastewater tank 201.

[0041] During the heating process, the water in the wastewater gradually evaporates, thereby concentrating the organic matter and salts in the wastewater. As the water continues to evaporate, the solute concentration in the wastewater gradually increases. When it reaches saturation, the solute will precipitate in the form of crystals.

[0042] When the cellulose organic wastewater is heated to form water vapor, the water vapor formed by the cellulose organic wastewater can be condensed into crystals, and then the crystals can be collected to facilitate the next operation. The cellulose organic wastewater can be heated by heating the water through the electric heating rod 204, thereby reducing costs. Even if the electric heating rod 204 is damaged, it only needs to be replaced with a new one.

[0043] When the solar panel 6 is exposed to the sun, it converts light energy into electrical energy. The battery 7 is used to store this electrical energy, and then the electricity in the battery 7 is used to start the servo motor 12. The servo motor 12 drives the connecting rod 10 to rotate. When the connecting rod 10 rotates, it drives multiple fan blades 11 to rotate. The rotating fan blades 11 can accelerate the circulation of water in the square water tank 202, making the water heated more evenly, which is convenient for heating the cellulosic organic wastewater in the wastewater tank 201.
