Abstract

The invention relates to an energy-saving evaporating process and equipment for a L-phenylalanine brine solution, belonging to the technical field of efficient energy saving and environmental protection. The process comprises the following steps of: preheating a 1 percent concentration of feed solution to 50-60 DEG C with a preheater 4; making the preheated feed solution enter the tube pass and shell pass of a falling film evaporator 7 and a climbing film evaporator 8 for secondary vapor heat exchange at 78-80 DEG C, heating to 70 DEG C, and evaporating in a way of combining a falling film with a climbing film to generate secondary vapor and a concentrated solution; making the secondary vapor and the concentrated solution enter a separator 9 for vapor-liquid separation; making the separated secondary vapor enter a centrifugal compressor 10 for compressing and increasing caloric content, heating to 78-80 DEG C for serving as a heating source of the evaporators 7 and 8, and heating and evaporating the feed solution; discharging the concentrated solution of which the concentration is controlled at 3 percent from the separator 9, and returning the concentrated solution of which the concentration does not reach 3 percent to the climbing film evaporator 8 for continually evaporating and concentrating. The system has the advantages of self-heat balance, small using amount of live vapor, low running cost, high efficiency and saving in energy.

Description

technical field

[0001] The invention relates to an energy-saving process and equipment for evaporating L-phenylalanine salt solution, which belongs to the technical field of high efficiency and energy saving, and also belongs to the technical field of environmental protection. Background technique

[0002] Evaporation and concentration are very typical chemical unit operations in the industry, and are widely used in petroleum, chemical, food, drying and other industries. The heat source of evaporation and concentration operation is mainly heated by saturated steam. For materials with low concentration and large processing capacity, steam consumes a considerable amount of energy. For enterprises that need to purchase steam, as the market steam price rises, the steam operating costs of enterprises Higher and higher, how to reduce the operating cost of the device and save energy is the great concern of the majority of scientific and technological workers. At present, the evapo...
