Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the existing technology reduces the accumulation of impurities on the surface of the membrane through vertical or horizontal membrane vibration, but the vibration device of the above technology cannot effectively remove the impurities adhered to the membrane surface and the impurities in the membrane pores. The clogged impurities cannot effectively solve the problem of membrane fouling in oil treatment; and then propose a method that can effectively remove impurities in the membrane pores and remove impurities adhering to the membrane surface, thereby solving the problem of membrane fouling in oil treatment Three-dimensional frequency conversion vibration device

Embodiment 2

[0040] On this basis, as a variable embodiment, the frequency of the AC output of the frequency converter changes periodically, and then the horizontal vibrator 1 and the vertical vibrator 2 are controlled to drive the membrane assembly to move horizontally and vertically respectively. Perform frequency conversion vibration with the same cycle to remove impurity particles of different sizes. Preferably, in each cycle, the vibration frequency is increased every 1ms-1s until it increases from 10Hz to 40-50Hz, and then every 1ms-1s Decrease once until it drops to 10Hz; the way of increment and decrement is to increase or decrease 3Hz at a constant speed within 1ms; in this embodiment, the vibration frequency is incremented every 1ms until it increases from 10Hz to 40Hz, and then every 1ms Decrease once until it drops to 10Hz. The way of increment and decrement is to increase or decrease 3Hz at a constant speed within 1ms, such as image 3 shown.

Embodiment 3

[0042] On the basis of the above, as an alternative embodiment, as shown in 4, the vertical vibrator 2 includes a vertical support 22 for connecting with the membrane assembly, a second motor 23, a horizontal shaft 24, a second connecting rod 25 and a vertical eccentric shaft 26, the bottom of the vertical support 22 is connected with the horizontal support 3, the horizontal rotating shaft 24 runs through the vertical support 22, and one end of the horizontal rotating shaft 24 passes through the second The connecting rod 25 is connected with the second motor 23, and the other end is provided with the vertical eccentric shaft 26, the second motor 23 is connected with the frequency converter, and the frequency converter controls the second motor 23 to rotate with variable frequency, while the second The second motor 23 drives the vertical eccentric shaft 26 to rotate vertically with frequency conversion through the horizontal rotating shaft 24 , and then the vertical eccentric sh...

Abstract

The invention discloses a three-dimensional frequency conversion vibrating device, which comprises a horizontal vibrator used to vibrate the film along the horizontal direction; a vertical vibrator used to vibrate the film along the vertical direction at the same time; The vertical vibrator is connected to make the vibration frequency of the horizontal vibrator and the vertical vibrator change in the frequency conversion range of 10-100 Hz respectively. The present invention also proposes a membrane treatment system using the above-mentioned three-dimensional frequency conversion vibration device. The above vibrating device and membrane treatment system are suitable for treating oil products to solve the problem of membrane blockage caused by impurities with different particle sizes in the oil products.

Description

technical field [0001] The invention relates to a three-dimensional frequency conversion vibration device for solving the problem of membrane pollution, and a membrane treatment system using the vibration device, belonging to the technical field of membrane treatment. Background technique [0002] Membrane separation is a unit operation technology that separates components of different sizes in the feed liquid, and is widely used in sewage treatment, water supply and drainage, beverage production, pharmaceutical production and oil treatment and other fields. In the application of membrane separation technology, the problem of membrane fouling is more affected. With the extension of use time, impurities in the high-pressure side feed liquid tend to accumulate on the surface of the membrane, resulting in a decrease in membrane flux and a decrease in treatment efficiency. At the same time, it also seriously affects the membrane. service life. Especially for the membrane used f...
