Embodiment Construction

[0033] specific implementation plan

[0034] Attached below figure 1 The energy-saving process and equipment for evaporation of L-phenylalanine salt solution are further described.

[0035] like figure 1 As shown, the temperature in the raw material tank (1) is 20-30° C., and the low concentration L-phenylalanine salt solution raw material solution with a concentration of about 1% is pumped into the shell-and-tube preheater (4) through the raw material pump (2). In the tube side, it exchanges heat with the condensed water from the shell side of the falling film evaporator (7) and the rising film evaporator (8), and the raw material liquid is preheated to 50-60°C; the preheated raw material liquid enters The tube side of the falling film evaporator (7) is heated and evaporated in the way of falling film, and then enters the tube side of the rising film evaporator (8) to be heated and evaporated in the way of rising film to generate steam and concentrated liquid, steam and c...

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...
