The whole design idea of a kind of catalyst mother liquid disposal recycling system of the utility model and its treatment process are as follows:
Through analysis and research, discussion demonstration and many experiments to Shandong Qi Wangda catalyst mother liquor, at comprehensive analysis
On the basis of the factors such as reason amount, pH value, TDS and evaporating temperature, determine that quasi- disposing mother liquor technology is aided with the skills such as steam raising, drying
Art is applied in the technical solution, realizes the recycling of valuable material in mother liquor.
According to the catalyst mother liquor characteristic and process requirement, needs emphasis to do when designing entire processing system and examine as follows
Consider:
1, catalyst mother liquor water content and COD value are all very high, influence raw material reuse.Through analyzing, the COD overwhelming majority is by mother
The organic matter triethylamine dissolved in liquid causes.It is verified, utility is returned, condensed water is sent back to by laboratory experiment
Commercial cultivation.
2, because there is the presence of solvable silicon, gel or floccule can be formed, fouling and then shadow are easy in evaporating concentration process
Heat transfer effect is rung, therefore, it is necessary in structure (antiscale) the material type selecting and coating of the determination of the parameters such as flow, temperature and equipment
It is in optimized selection.
3, there are the elevation of boiling point and section of about 10 DEG C (being concentrated by evaporation lab scale by laboratory to obtain) from catalyst mother liquor highest
Energy angle considers, selects the temperature rise of the evaporation profiles and vapour compression machine of evaporator.The continuous-stable and peace run from system
Full property considers that key equipment should be using internationally renowned brand (such as vapour compression machine, driving variable-frequency motor, frequency converter and all kinds of biographies
Sensor etc.).
