preparation example Construction

[0029] The preparation method of the cleaning agent of the present invention: add the above components into a corrosion-resistant reactor and mix evenly, stir and dissolve with 35-50°C deionized water, and finally add a sufficient amount of deionized water to obtain a cleaning composition containing 1-2%wt Divided detergent.

[0030] The application method of the cleaning agent made above to the Chinese medicine liquid preparation polluted film is as follows:

[0031] 1. Empty the material liquid, rinse the device with deionized water until the effluent is colorless;

[0032] 2. Add the cleaning agent of the present invention, at a temperature of 50-60°C, and cycle cleaning for 30 minutes;

[0033] 3. Empty the cleaning agent and rinse the device with deionized water;

[0034] 4. EDTA, 1-2% wtHCl cleaning, temperature 50-60 ℃, cycle cleaning 30min;

[0035] 5. Empty and rinse the device with deionized water;

[0036] 6. Empty and ready for use.

Abstract

The invention relates to a ceramic membrane cleaning agent, which is characterized by comprising the following compositions in portion by mass: 50 to 60 mass portions of sodium hydroxide, 20 to 30 mass portions of calcium hydroxide, 5 to 10 mass portions of sodium hypochlorite, 5 to 10 mass portions of sodium dodecyl benzene sulfonate, 1 to 5 mass portions of sodium tetraborate, 1 to 10 mass portions of sodium silicate and 1 to 5 mass portions of methyl cellulose. The cleaning agent is simple and convenient to prepare, has good cleaning effect, has strong applicability on a Chinese medicinal liquid preparation, reduces the cleaning frequency of a membrane, does not need to disassemble a membrane tube, is easy and convenient to clean, is quick to restore the membrane flux, greatly shortensthe cleaning time, reduces the energy consumption of a system, has small damage to the membrane tube, does not influence the service life of the membrane tube, avoids secondary pollution caused by thecleaning agent, and accelerates system regeneration.

Description

1. Technical field [0001] The invention relates to a membrane cleaning agent, in particular to a cleaning agent suitable for ceramic membrane microfiltration of liquid preparations of traditional Chinese medicine. 2. Background technology [0002] As the main body of traditional Chinese medicine, plant medicinal materials are the tissues and organs of plants, whether they are roots, rhizomes, stems, skins, leaves, flowers, or fruits. The decoction contains various active and effective ingredients. In addition, without exception, it contains a large number of components that constitute the cell walls of various tissues and organs, as well as stored nutrients such as starch. Studies have shown that the chemical components of plant cell walls are mainly cellulose, hemicellulose, pectin, polysaccharides and proteins, etc. Their molecular weight is very large, and except for a few, they generally have no pharmacological activity. [0003] Traditional Chinese medicine liquid prep...
