Problems solved by technology

However, the adjustable output power of existing ultrasonic cleaners is only a few gears, so the range of corresponding ultrasonic intensity is limited, and continuous fine adjustment of ultrasonic intensity cannot be realized, so the research results are relatively incomplete
In addition, the above-mentioned experimental methods all rely on the experimenters to detect or regulate each parameter, the workload is relatively large, and it is easy to produce certain errors, which will affect the experimental results.

Embodiment Construction

[0022] see figure 1 The overall structure of a kind of simulated ultrasonic filter-aided membrane loss experimental device of the present invention shown has an experimental pool 1, and the inside of the experimental pool 1 is a cavity, and a flat film 31 and an ultrasonic transducer box 15 are placed inside the experimental pool 1 . The ultrasonic transducer box 15 is vertically located on the right side inside the test pool 1, and divides the inside of the test pool 1 into left and right areas, and the left area stores the feed liquid. The front and back walls of the ultrasonic transducer box 15 are in sealed contact with the inner walls of the front and rear sides of the test pool 1 as much as possible to prevent the material liquid from the left area from infiltrating into the right area, and it is also necessary to ensure that the ultrasonic transducer box 15 can move left and right in the test pool 1. In the left area, a flat film 31 is vertically arranged, and the flat...

Abstract

The invention discloses an ultrasonic auxiliary filtering membrane damage simulation test device and a test method. An ultrasonic transducer box is vertically positioned at the right side inside a test pool for dividing the inside of the test pool into a left region and a right region; the ultrasonic transducer box can leftwards and rightwards move and is in sealed contact with the test pool; the left side region is vertically provided with a flat membrane; the flat membrane is clamped by a front side clamp plate and a right side clamp plate; a sound intensity probe is arranged at the front wall part of the back side clamp plate; the center part of the ultrasonic transducer box is connected with the left end of a horizontal screw rod in a rolling way; the right end of the screw rod extends out of the test pool through the right side wall of the test pool and is axially connected with a screw nut with teeth in a sleeving way; the screw nut with teeth is connected with a gear through a belt with teeth; the gear is connected with an output shaft of a step motor in a concentric way. On the premise of the fixed ultrasonic output power of each gear, the rotation of the step motor is precisely controlled by combining an MCU (micro control unit) control system; the ultrasonic intensity is changed through changing the distance between an ultrasonic source and the membrane; the effect that the ultrasonic intensity is roughly adjusted at first and is then finely adjusted is achieved; the obtained rest data is more comprehensive.

Description

technical field [0001] The invention relates to the field of membrane separation, in particular to an experimental device and method for simulating ultrasonic filter-aided membrane damage. Background technique [0002] Membrane separation is the separation, classification, purification and enrichment of multi-component fluid substances. It has unique advantages such as high efficiency, energy saving, and easy process control. However, concentration polarization and membrane fouling are two main problems in the membrane separation process, which will damage the performance of the membrane and eventually shorten the life of the membrane, increase the operation and maintenance costs of the membrane, and will affect the quality of the product and the target product. Yield decreased. In order to improve membrane separation efficiency and reduce concentration polarization and membrane fouling, ultrasonic waves have been used to strengthen the membrane separation process in recent...
