Description
Technical field:
The utility model relates in the industry such as chemical industry, food, pharmacy and environmental protection, is used for the concentration device to feed liquid, is specially a kind of multiple-effect evaporation enrichment facility.
Background technology:
Existing three-effect evaporation and condensation technology, though brought into play very big effect in industries such as chemical industry, pharmacy, but still following deficiency is arranged:
1), the heating tube of heater inside stops up easily:
Because feed liquid is Natural Circulation in evaporation process, often knot is on the inwall of heating tube in the concentration raising back of material, and when particularly evaporating inorganic salt solution, oversaturated feed liquid is at the pipe intercrystalline, thus the obstruction heating tube.When clearing up these pipelines, need take a long time and cost, cleaning can also not damage water back at that time.
2), the film-cooled heat of vacuum condenser is bigger:
Because imitating heater to two, uses the indirect steam that 1st effective evaporator produces, the double evaporation-cooling that 2nd effect evaporator produces uses for the triple effect heater, from two imitate water that heaters and triple effect heater discharge and not condenser enter liquid seal trough, steam in the liquid seal trough also will could cool off by vacuum condenser, so the film-cooled heat of vacuum condenser needs enough could satisfy technological requirement greatly.Even like this, still very high from the temperature of liquid seal trough discharge water, there is waste of steam.
3), electric power consumption is higher:
Because the area of vacuum condenser is big, need the vavuum pump of supporting big discharge capacity or the requirement that the vacuum unit could satisfy evaporation capacity in the evaporation process, so the power consumption of vavuum pump or vacuum unit is higher.
The utility model content:
The purpose of this utility model is to design a kind of multiple-effect evaporation enrichment facility for overcoming above deficiency, make whole concentration process steam be utilized effectively, material can blocking pipe in concentration process, and energy consumption reduces greatly, thereby has really realized energy-saving and cost-reducing effect.
The purpose of this utility model is achieved by the following technical solution:
The multiple-effect evaporation enrichment facility, it is characterized in that: this device comprises the feed pump (12) that connects by pipeline, one imitate vapo(u)rization system by what heater (1) and evaporimeter (2) connected to form, two imitate vapo(u)rization systems by what heater (4) and evaporimeter (5) connected to form, the triple effect evaporation system that connects to form by heater (7) and evaporimeter (8), by condenser (9) and liquid seal trough (10), the low-pressure drainage system of draining pump (15) and vavuum pump (16) connection group, the pre-heating system that connects to form by preheater (3) and preheater (6), the forced circulation system that connects to form by circulating pump (11) and circulating pump (13) and form by the discharge system that discharging pump (14) connects to form.By realizing utilizing indirect steam with upper type and preventing the generation of phenomenon such as line clogging.
The course of work is as follows: mother liquor is by feed pump (12), flow is controlled by flowmeter, enter one-level preheater (3) after entering secondary preheater (6), enter one again and imitate heater (1), feed liquid sprays into 1st effective evaporator (2) from heater (1) via jet pipe, moisture evaporates from top, and heavy component is got back to evaporimeter (2) bottom, is heated once more and sprays into evaporimeter (2) to form circulation.Nebulize when feed liquid sprays into evaporimeter, moisture evaporates rapidly.The steam that is come out by 1st effective evaporator (2) evaporated on top enters heat supply in two effect heater (4) shells, and tail end connects condenser and drains by vacuum.One heat of imitating heater is given altogether by Boiler Steam, heats feed liquid at a shell of imitating heater (1).Because vacuum action, the feed liquid of the process once concentration of 1st effective evaporator bottom enters two and imitates heater (4), imitates the inner heating of heater (4) two, and light component is because vacuum action sprays into the middle and upper part gasification of 2nd effect evaporator (5) from its top.Feed liquid through secondary concentration enters triple effect evaporator by its bottom.The secondary steam that the 2nd effect evaporator top produces enters heat supply in triple effect evaporator (7) shell, and tail end connects condenser and drains by vacuum.Last feed liquid reaches needed concentration in triple effect evaporator (8).
Mainly the effect that has increased preheater (3,6) and circulating pump (11,13), preheater (1) in this process: 1, two imitate the steam that heaters and triple effect heater do not use up and enter preheater (3,6), do not coagulate water and enter liquid seal trough (10) together.Can maximally utilise heat energy like this material is carried out preheating, after preheating, the temperature of charge that enters in the 1st effective evaporator can improve 20-30 ℃.2, bottom at two effects and triple effect evaporator has respectively installed a circulating pump (11,13) additional, the one, improve the circulation rate of material in evaporimeter, main is, when concentrating salt-containing solutions, stop the crystallization of material heating tube inside in heater, thereby effectively guaranteed carrying out smoothly of evaporation process.
