Problems solved by technology

However, the existing experimental or batch-scale membrane separation equipment on the market today does not have an effective temperature control system to regulate the operating temperature of the material, and all of them are in a single form such as a flat or roll membrane element, or The complete set of devices manufactured with a single membrane element at an operating pressure of only low or high pressure, the experimental data obtained by this deviation is too large
Therefore, the existing complete sets o

example 1

[0058] Example 1, ultrafiltration purification test of chlorogenic acid in honeysuckle water extract

[0059] Weigh 2.5kg of honeysuckle, add 1.0, 0.7, 0.5, 0.5, 0.5 times the amount of water to extract and reflux 5 times, each time for 1.5h, coarse filter, and combine the filtrates to obtain the honeysuckle water extract. The content of chlorogenic acid in the water extract is measured, and the water extract is used as the raw material solution for ultrafiltration to carry out ultrafiltration membrane separation. A flat-plate ultrafiltration membrane and a spiral-wound ultrafiltration membrane with a cut-off molecular weight (MWCO) of 20-50kDa were selected respectively, and a parallel test operation was carried out on the water extract of chlorogenic acid. The specific operation is as follows: install the flat membrane into the M-02 module, and install the spiral-wound membrane into the M-03 module. Chlorogenic acid is a heat-sensitive substance, and the temperature should ...

[0060] Example two, membrane method purification and concentration test of chlorogenic acid in honeysuckle water extract

[0061] According to example one method, obtain honeysuckle aqueous extract. Select spiral-wound ultrafiltration membranes and spiral-wound nanofiltration membranes with MWCO of 20-50kDa and 150-300Da, respectively, and put them into M-03 and M-04 modules, and prepare a pool by yourself. Add an appropriate amount of water into the constant temperature bath as a refrigerant, turn on the power button of the constant temperature bath, set the temperature to 25°C, connect the heat exchange device and the circulation pipeline, and turn on the circulation pump B-03 to circulate and cool down. Take 10L honeysuckle water extract, put it in the raw water pool, open the valves ZF-01, ZF-04, start the low-pressure pump B-01, adjust the closing degree of the valves ZF-03, ZF-08, ZF-12 to control the feeding flow and operating pressure. Under the operating pressure of...

The invention has the obvious characteristics that the membrane process of RO or NF and UF or MF four membrane components and four separation functions are combined, a high-pressure membrane system and a low-pressure membrane system are integrated, the operating temperature is controllable, the separation functions are diversified, the operating process is combined, the equipment integration degree is high, and the device is suitable for laboratory research and laboratory-enlarged research or batch operation of different raw materials and is particularly suitable for separation, extraction, purification and concentration operations of heat sensitive materials, so that a reliable design basis is provided for engineering development of large-scale application and manufacture of complete sets of membrane separation equipment.

Description

technical field [0001] The invention relates to a multi-component membrane separation device with controllable operating temperature and a process thereof, which belongs to the field of fluid separation of water and waste water treatment, food, biology, pharmacy, fine chemical industry and the like. Background technique [0002] Membrane separation technology has the advantages of high efficiency, energy saving, environmental protection, and easy operation, so it is widely used in the separation, classification, impurity removal and concentration of materials with different physical and chemical properties in today's industrial production. The four membrane processes of reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) driven by pressure are due to the sequential increase of the pore size of the membrane. The mixture of different sizes can be finely separated, purified and concentrated, and can be operated efficiently for the specific ...
