Alcohol Recovery Condenser for Heparin

Abstract

The invention relates to a recycling condenser for ethyl alcohol for heparin. The recycling condenser comprises a shell, cooling water pipes, separating plates and end covers. The separating plates are installed at the two ends of the shell and provided with a plurality of round holes. The cooling water pipes are installed between the round holes. The end covers are installed at the two ends of the shell. A cooling water inlet is formed in the end cover on the right side. A cooling water outlet is formed in the end cover on the left side. An ethyl alcohol steam inlet is formed in the upper end of the shell. An ethyl alcohol outlet is formed in the lower end of the shell. The outer side of the separating plate on the left side of the shell is connected with a sealing covering plate, a flow guide pipe is installed in the middle of the sealing covering plate, and an outlet of the flow guide pipe is upward and located in the uppermost end of the corresponding end cover. Three dripping plates are transversely installed in the middle of the shell, evenly installed in the upper, middle and lower positions inside the shell respectively, and located among the multiple cooling water pipes. The recycling condenser for ethyl alcohol for heparin has the advantages of being simple and ingenious in design, avoiding the phenomenon of corrosion of condensate water above to a row of tubes at the interface of the condenser, being small in loss of ethyl alcohol, and paying the condensation effect to the maximum extent.

Description

technical field [0001] The invention relates to the field of condensers, in particular to an alcohol recovery condenser for heparin. Background technique [0002] In the production process of heparin, alcohol is one of the required auxiliary materials. Effective recycling and reuse of waste alcohol is of great significance for enterprises to reduce costs and improve efficiency. Alcohol recovery generally uses tube-and-tube condensers, but traditional tube-and-tube condensers The condenser has the characteristics of low utilization efficiency of the tubes and the inhomogeneous cooling liquid of the upper and lower tubes in the condenser. In addition, the alcohol to be recovered produced by heparin contains a large amount of alkali, salt and grease. The two media will be corrosive to the condensing equipment made of poor corrosion resistance, so it is of great significance to change the traditional shell and tube condenser.

[0002] In the production process of heparin, alcohol is one of the required auxiliary materials. Effective recycling and reuse of waste alcohol is of great significance for enterprises to reduce costs and improve efficiency. Alcohol recovery generally uses tube-and-tube condensers, but traditional tube-and-tube condensers The condenser has the characteristics of low utilization efficiency of the tubes and the inhomogeneous cooling liquid of the upper and lower tubes in the condenser. In addition, the alcohol to be recovered produced by heparin contains a large amount of alkali, salt and grease. The two media will be corrosive to the condensing equipment made of poor corrosion-resistant materials, so it is of great significance to change the traditional shell and tube condenser

[0003] There is a problem: if the pressure of the condensed water is low from the inlet to the outlet, the condensed water in the tubes below the condenser will be larger than the condensed water above the condenser, even in the tubes above the condenser. Air, and a vacuum-like form is formed inside, so that the condensed water has an interface in the condenser, so that the condensation efficiency of the condenser will be reduced (the condensation area will be reduced), and the alcohol vapor recovered from alcohol comes in from the steam inlet above When the temperature is high, the condensed water above will corrode the tubes at the interface of the condenser

When the recovered alcohol vapor enters from the upper inlet, the cold column tube will form alcohol liquid, which will quickly flow out from the alcohol outlet. In this way, the temperature of the cooled alcohol is often too high, the loss of alcohol is serious, and the condenser does not maximize the performance of condensation. efficiency
