Abstract

The invention belongs to the technical field of bioengineering. In view of a technical problem that an existing tube is easy to scale, the invention provides a method for preventing a tube from scaling by using a tubular heat exchanger for concentration of an aqueous protein solution, wherein the method comprises a step of using the tubular heat exchanger for exchanging heat with the aqueous protein solution; the method is characterized in that an independent flash evaporation region is arranged above the interior of the tubular heat exchanger; a top end of the tube extends into the flash evaporation region; a tube cavity of the tube is always filled with a liquid material during heat exchanging operation; the heated liquid material is boiled in the flash evaporation region to form a gas-liquid mixture; an evaporation tank is also provided; the gas-liquid mixture in the flash evaporation region is injected into a material storage region at the bottom of the evaporation tank; gas-liquidseparation is performed by the evaporation tank; the concentrated aqueous protein solution is settled at the bottom of the evaporation tank; and an evaporated gas is discharged from an exhaust port in the top of the evaporation tank. The method provided by the invention has a beneficial effect of preventing the tube from drywall phenomenon to avoid occurrence of scaling in the tube.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and specifically refers to a method for preventing tube scaling when using a tube heat exchanger to concentrate an aqueous protein solution. Background technique [0002] Fish protease hydrolyzate, containing 5-15% protein, needs to be evaporated to remove water and concentrated to 50-70%. The usual evaporation methods, such as rising film or falling film evaporation, are heated in a tube heat exchanger. With the heating, the water in the protease hydrolyzate is continuously evaporated, so as to achieve the purpose of concentration. However, during use, it was found that since heating and evaporation are carried out in the tube heat exchanger at the same time, dry wall phenomenon occurs in the inner wall of the tube during evaporation and concentration, and the protein adheres to the inner wall of the tube, resulting in The walls gradually become clogged with scale. Therefore, the tubes ...
