Vibration device for membrane module

Abstract

The invention discloses a vibrating device for a membrane component, which comprises a suspension component for suspending the membrane component, a roller component connected to the suspension component, a support component for suspending the roller component, and a driving component arranged on the support component and used for driving the suspension component to reciprocate relative to the support component, the supporting assembly comprises a guide rail used for hanging the roller assembly. The supporting assembly is arranged above the hanging assembly, and the guide rails respectively form angles with the horizontal plane and the vertical direction; when the hanging assembly reciprocates relative to the supporting assembly, the roller assembly reciprocates in the length extension direction of the guide rail. According to the vibration device for the membrane module, the membrane module can be driven to linearly reciprocate along a three-dimensional space, the structure is simple, and the equipment cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of water treatment and separation equipment, in particular to a vibration device for a membrane module. Background technique [0002] When the existing MBR membrane filters sewage, the membrane flux will attenuate due to the adsorption and accumulation of dissolved organic matter, colloids, microorganisms, fiber debris, etc. present in the sewage on the surface of the membrane. Generally, aeration is used to flush the membrane filaments to slow down the membrane fouling. [0003] In the prior art, the vibration of the membrane module is generally achieved through horizontal reciprocating vibration mode, reciprocating vibration mode, up and down reciprocating vibration mode, and rotational reciprocating vibration mode. However, there are the following problems: in the vibration mode of horizontal reciprocating motion and up-and-down reciprocating motion, the main force direction of the membrane filament is s...

Problems solved by technology

However, there are the following problems: in the vibration mode of horizontal reciprocating motion and up-and-down reciprocating motion, the main force direction of the membrane filament is single, and the scouring effect is limited; The problem of uneven distribution of membrane fouling is likely to cause imbalance of membrane flux and further aggravate membrane fouling; in the vibration mode of rotary reciprocating motion, in addition to the defect of reciprocating vibration mode, there is also the limitation of the installation environment of membrane modules that is difficult to implement The problem

[0004] In view of the above problems, the Chinese patent No. CN201410040705.6 discloses a three-dimensional frequency conversion vibration device and its membrane processing system, which can effectively wash the membrane filaments through horizontal and vertical vibrations, but requires a horizontal vibrator Simultaneously acting with the vertical vibrator, the structure is more complicated, and the equipment cost is relatively high
