From the view of the performance process of the value strength of water ring vacuum pump, it is necessary to exert its overall value ability through efficient product application, to enhance the quality strength of equipment by using the advantages of equipment, and to develop its practical value ability from the development of the quality and superior ability of the whole application, so as to fully improve the development strength of its product application effect, so as to make progress. Step by step to enhance the exploiting advantages of its product application ability, to comprehensively drive the quality advantage to enhance the overall practicability of the equipment.
With enterprises looking for more scientific, energy-saving and environmental protection equipment, the application of water-ring vacuum pump in ketone production has been deepened.
First of all, the single-stage water-ring vacuum pump has been successfully applied in the production of acetone. Because of the technological progress of equipment manufacturing and the improvement of processing accuracy, the performance of the single-stage water-ring vacuum pump which could not meet the technological requirements before has been greatly improved. In addition, the single-stage water-ring vacuum pump has the advantages of high efficiency, low energy consumption, low calorific value and less self-agglomeration of acetone. Gradually by vinyl ketone manufacturers.
Secondly, the improvement of circulating medium. German Hurst Company proposed a new method of using diketene as circulating fluid to transport ethylene ketone. By adjusting the ratio of two kinds of diketene liquids in circulating fluid (one containing ethylene ketone and one without ethylene ketone), different quantities of ketone and diketene were obtained. This method is suitable for the production of diketone, but for the production of acetic anhydride. It is a reasonable and scientific choice to use acetic acid as circulating liquid and adjust the ratio of acetic acid to acetic anhydride to get different amounts of acetic anhydride and acetone gas. However, it is necessary to derive the heat released during the production of acetone in time.
