Description

Technical Field

[0001] The utility model relates to the technical field of membrane separation and cleaning, in particular to a membrane separation and cleaning device for phosphate ester production. Background Art

[0002] Phosphate ester, also known as orthophosphate ester, is prepared by a special catalytic esterification method. During the production of phosphate ester, other impurities are produced, and membrane separation is required to remove impurities from the raw materials. After the membrane separation device has been used for a period of time, a phosphate ester production membrane separation cleaning device is required to clean it.

[0003] According to the description of a membrane separation device disclosed in the patent website (authorization announcement number: CN 214210080 U), "The utility model relates to the technical field of membrane separation devices, and in particular to a membrane separation device, including a separation device body, the separation device body including a cleaning component, an ultrasonic generator, a first separation membrane and a second separation membrane, an ultrasonic generator is arranged on the upper side of the cleaning component, a first separation membrane is arranged on the left side of the cleaning component, and a second separation membrane is arranged on the right side of the cleaning component. When the separation membrane needs to be cleaned, the ultrasonic generator can be used to vibrate the water in the separation box, thereby driving the impurities on the separation membrane to fall off, and the cleaning effect is better, avoiding clogging of the separation membrane due to a large number of impurities, so that the separation membrane can be better used, and the overall device structure is simple and more practical."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model uses an ultrasonic generator to vibrate the water in the separation box, thereby driving the impurities on the separation membrane to fall off. The cleaned impurities can fall to the bottom of the separation box through the collecting groove. After sedimentation, the cleaning box cover can be opened and then cleaned. However, in actual use, the ultrasonic generator drives the water to vibrate to clean the separation membrane, so that the impurities are shaken off inside the separation box. The water vibration makes the water always active, and the impurities will not settle in the separation box. Even if they enter the separation box, they will still float up under the vibration of the water. The ultrasonic generator can only prevent the separation membrane from being blocked, but cannot clean the impurities in the separation device body, which is not conducive to the next use. Therefore, it is necessary to improve a membrane separation cleaning device for phosphate ester production to solve the above problems. Utility Model Content
