[0027] A discharge valve 15 is installed at the lower end of the pre-reactor 2, and the discharge valve 15 on the pre-reactor 2 is connected to the valve port on one side of the electric-controlled three-way valve 18 through the second delivery pipe 16. A first delivery pipe 12 is installed on one side of the two-in-one hot water tank 1, and one end of the first delivery pipe 12 is connected to the second delivery pipe 16 through a connecting valve 17. The output end of the air compressor 4 is connected to the valve port on the other side of the electric-controlled three-way valve 18. A pressure gauge 5 is installed on the output end of the air compressor 4. A feed valve 11 is installed on the upper end of the two-in-one hot water tank 1;

[0028] A solid discharge valve 19, which is installed at the lower end of the two-in-one filter press device 3;

[0029] The liquid discharge valve 20 is installed on the outer wall of one side of the two-in-one filter press device 3 .

[0030] See also Figure 2 A filter element 22 is installed inside the two-in-one filter press device 3, and the filter element 22 is used to separate the washing material and the process water during washing.

[0031] See also Figure 3 The filter element 22 includes a metal guard mesh 221 and a filter cloth layer 222. The metal guard mesh 221 is arranged on both sides of the outer wall of the filter cloth layer 222. The double-layer sandwiched metal guard mesh 221 ensures the structural strength of the filter element 22 when it is subjected to air pressure.

[0032] See also Figure 1 A first jacket 7 is installed on the outer wall of the two-in-one hot water pool 1, and a second jacket 8 is installed on the outer wall of the pre-reactor 2. The outer walls of one side of the first jacket 7 and the second jacket 8 are connected with the steam inlet pipe and the circulating water return pipe through a first three-way valve 9, and one side of the lower end of the first jacket 7 and the second jacket 8 is connected with the steam outlet pipe and the circulating water inlet pipe through a second three-way valve 10.

[0035] Working principle: When in use, first add the raw material of ultraviolet absorber into the pre-reactor 2 for reaction, and after the reaction is complete, discharge the material into the two-in-one filter press device 3, pump the process water into the two-in-one hot water pool 1 through the feed valve 11, open the steam valve heating jacket, heat the process water, and then continue to pump the heated water into the two-in-one filter press device 3. Since the raw material is placed in the filter element 22, the process water can flow out along the filter layer after entering the filter element 22 and be discharged along the liquid discharge valve 20, while the reaction material is in the filter element 22. After washing, the three-way valve 18 is switched to the air compressor 4 passage, and the air compressor 4 continuously supplies compressed air to the two-in-one filter press device 3 to perform filter press treatment on the reaction material in the filter element 22. During the filter press process, the pressure gauge 5 detects and controls the pressure value to avoid excessive pressure in the two-in-one filter press device 3. The water after filter press is discharged into the sewage treatment system by the sewage pump 6 for reuse, and the reaction material is discharged from the bottom solid discharge valve 19 for subsequent drying treatment.
