In concentration, the materials do not block a pipe so that energy consumption is greatly reduced and energy saving and consumption reduction are really realized. The continuous circulation evaporation concentration device comprises a charging pump connected by a pipe, a primary evaporation system comprising a heater and an evaporator connected with each other, a secondary evaporation system comprising a heater and an evaporator connected with each other, a tertiary evaporation system comprising a heater and an evaporator connected with each other, a vacuum drainage system comprising a condenser, a liquid seal trough, a drainage pump and a vacuum pump connected with each other, a pre-heating system comprising a heater and a pre-heater connected with each other, a forced circulation system comprising circulating pumps connected with each other, and a discharging system comprising a connected discharging pump. The continuous circulation evaporation concentration device realizes utilization of secondary steam and prevention of pipe blocking.
Description
Technical field:
The present invention relates to, in the industry such as chemical industry, food, pharmacy and environmental protection, for the concentration equipment to feed liquid, be specially a kind of continuous circulation evaporation concentration equipment.
Background technology:
Existing three-effect evaporation and condensation technology, although in industries such as chemical industry, pharmacy, brought into play very large effect, but still have following deficiency:
1), the heating tube of heater inside easily stops up:
Because feed liquid is Natural Circulation in evaporation process, the concentration of material improves by often tying on the inwall of heating tube, and while particularly evaporating inorganic salt solution, oversaturated feed liquid is at pipe intercrystalline, thus obstruction heating tube.While clearing up these pipelines, need to 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 larger:
The indirect steam producing due to 1st effective evaporator is used to two effect heaters, the double evaporation-cooling that 2nd effect evaporator produces is used to triple effect heater, the water of discharging from two effect heaters and triple effect heater and not condenser enter liquid seal trough, steam in liquid seal trough is also cooling by vacuum condenser ability, so the film-cooled heat of vacuum condenser needs enough could meet technological requirement greatly.Even like this, the temperature of discharging water from liquid seal trough is still very high, has waste of steam.
3), electric power consumption is higher:
Because the area of vacuum condenser is large, need the vavuum pump of supporting large discharge capacity or the requirement that vacuum unit could meet evaporation capacity in evaporation process, so the power consumption of vavuum pump or vacuum unit is higher.
Summary of the invention:
The object of the invention is to design a kind of continuous circulation evaporation concentration equipment for overcoming above deficiency, whole concentration process steam is 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 object of the invention is to be achieved through the following technical solutions:
Continuous circulation evaporation concentration equipment, it is characterized in that: this equipment comprises the feed pump (12) connecting by pipeline, the effect vapo(u)rization system being connected to form by heater (1) and evaporimeter (2), the two effect vapo(u)rization systems that connected to form by heater (4) and evaporimeter (5), the triple effect evaporation system being connected 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 being connected to form by preheater (3) and preheater (6), the forced circulation system being connected to form by circulating pump (11) and circulating pump (13), form with the discharge system being connected to form by discharging pump (14).By realize the generation that utilizes indirect steam and prevent the phenomenons such as line clogging with upper type.
The course of work is as follows: mother liquor is by feed pump (12), flow is controlled by flowmeter, after entering secondary preheater (6), enter one-level preheater (3), enter again an effect 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 again heated and sprays into evaporimeter (2) to form circulation.When feed liquid sprays into evaporimeter, nebulize, moisture evaporates rapidly.By 1st effective evaporator (2) evaporated on top steam out, enter heat supply in two effect heater (4) shells, tail end connects condenser and drains by vacuum.The heat of one effect heater is given altogether by Boiler Steam, in the shell heating feed liquid of an effect heater (1).Due to vacuum action, the feed liquid of the process once concentration of 1st effective evaporator bottom enters two effect heaters (4), in the inner heating of two effect heaters (4), light component is owing to gasifying in vacuum action sprays into 2nd effect evaporator (5) middle and upper part from its top.Feed liquid through secondary concentration enters triple effect evaporator by its bottom.The intermediate water steam that 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).
In this process, be mainly the effect that has increased preheater (3,6) and circulating pump (11,13), preheater (1): the steam that 1, two effect heaters and triple effect heater are not finished enters preheater (3,6), solidifying water enters liquid seal trough (10) together.Can maximally utilise like this heat energy material is carried out to preheating, after preheating, the temperature of charge entering in 1st effective evaporator can improve 20-30 ℃.2, in the bottom of two effects and triple effect evaporator, 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.
