The method of few Petropols washing Removal of catalyst emulsification, using the ratio 1 of polymer fluid and water:(3-4) is washed, generation
Waste water is still very big.The number of applying for a patent CN201520506809.1 introduces emulsion in a kind of reduction Petropols water wash system
Device, patent mentions and carries out interval Removal of catalyst, pilot process using neutralizing kettle and passes sequentially through alkali cleaning-washing-washing
Still unavoidably there is emulsion in special first step alkali cleaning, and generates a large amount of waste water.The number of applying for a patent
CN201520574795.7 introduces a kind of method of C5 Petropols continuous washing Removal of catalyst, realizes the company of water wash system
Continuous operation, the first water washing tank still unavoidably generate a large amount of waste water.
In conclusion emulsion, washing waste water amount are big, intermittently operated and water washing operations are cumbersome easily causes work labour
Intensity is big, and stirring is uneven, influences resin quality quality, generates a large amount of waste water, these, which have become, restricts Petropols washing hair
The principal element of exhibition.Therefore in order to solve problem above, it is necessary to develop a kind of novel Petropols water washing device to improve
Washing efficiency.
