Problems solved by technology

[0002] At present, the environmental protection pressure of paper mills and other enterprises is increasing, and energy saving and emission reduction are imminent. Generally, the white water of paper mills is collected and stored in a centralized manner, and is used for beating wood pulp broken paper. From the hydropulper to each pulp pool, papermaking The water in the pulp enters the entire large circulation system. The fine fibers in the white water become finer after repeated refining, and the fillers and fine fibers are distributed and purified throughout the system, which is very easy to deteriorate and corrupt, causing the paper machine to break. Using this white water reuse method , the water used per ton of paper is generally 10-15 cubic meters, which puts a lot of pressure on environmental protection

Embodiment 1

[0027] Embodiment 1 takes papermaking mid-stage water as an example

[0028] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes an n-level ultrasonic treatment device for reclaimed water reuse; the ultrasonic treatment device for water reuse in the middle section of papermaking includes a housing 1, an overflow port 2 is provided on the top of the housing 1, and a sewage outlet is provided at the bottom of the housing 1 3. A water filter pipe 4 is fixed inside the housing 1 through a stainless steel pipe; A supporting flange 6 is provided, and the supporting flange 6 is arranged on the top inside of the housing 1; the bottom end of the filter pipe 4 is provided with an ultrasonic transducer 7, and the ultrasonic transducer 7 includes an ultrasonic vibrator 11, and the ultrasonic vibrator 11 passes through a wire Connect with ultrasonic generator 8. The housing 1 includes a cylindrical barrel portion and a conical sediment...

Embodiment 2

[0030] Example 2 Domestic sewage treatment as an example

[0031] The water treatment method of the domestic sewage ultrasonic treatment system comprises the following steps:

[0032] (1) Primary treatment of domestic sewage: Store domestic sewage in the water collection well, and lift the domestic sewage to the first-level ultrasonic treatment device through the water pump. The ultrasonic transducer generates a strong magnetic field through the ultrasonic transducer, and the frequency of the ultrasonic vibrator is 33KHz. , sound energy density 0.08 W / cm 3 . The magnetic field reaches 5000 gauss. The domestic sewage is magnetized by a strong magnetic field to generate eddy current reaction, and the first homogeneous water distribution is completed. The solid matter quickly sinks to the bottom of the shell, and the clear water floats to overflow; The slurry tank is directly connected to the Internet to realize continuous filling;

[0033] (2) Clear water reprocessing: The cl...

Embodiment 3

[0036] Embodiment 3 Take the water in the middle section of mine coal washing as an example

[0037] This embodiment includes an n-level ultrasonic treatment device for reclaimed water reuse; the ultrasonic treatment device for water reuse in the middle section of mine coal washing and mine washing includes a housing 1, an overflow port 2 is provided at the top of the housing 1, and an overflow port 2 is provided at the bottom of the housing 1. There is a sewage outlet 3, and the inside of the housing 1 is fixed with a water filter pipe 4 through a stainless steel pipe; the upper end of the water filter pipe 4 protrudes from the top of the housing 1, and the upper end of the water filter pipe 4 is provided with a water inlet pipe 5; the water filter pipe 4 and the housing 1. The connection part is provided with a support flange 6, which is provided at the top inside the shell 1; the bottom end of the water filter pipe 4 is provided with an ultrasonic transducer 7, and the ultra...
