Description

The triple effect evaporation system of production of polyester enterprise-specific
Technical field
The utility model relates to a kind of polyester production facility, particularly a kind of triple effect evaporation system of production of polyester enterprise-specific.
Background technology
Polyamide fibre is again polycaprolactam fiber, and its raw materials for production are polyamide section.Polyamide section needs caprolactam solution to concentrate purification in process of production, main equipment for purifying is triple effect evaporator, triple effect evaporator is prior art, its principle is by an effect tank, two effect tanks and three evaporator series of triple effect tank get up, the indirect steam of previous stage evaporimeter becomes the heating steam of rear one-level evaporimeter, can form like this three grades concentrates, have advantages of energy-efficient, the shortcoming that this triple effect evaporator exists is: from the first steam jacket, the steam that the second steam jacket and the 3rd steam jacket steam (vapor) outlet are discharged is all directly emptying, this part steam pressure is 2.5 kilograms of left and right, containing a large amount of waste heats, drain very unfortunate, be unfavorable for energy-conservation.
Summary of the invention
The technical problem that will solve of the present utility model is: the triple effect evaporation system that a kind of more energy-conservation production of polyester enterprise-specific is provided.
The triple effect evaporation system of the production of polyester enterprise-specific that the utility model is designed, comprise steam supply house steward, feed tube and triple effect evaporator, described triple effect evaporator has an effect tank, two effect tank and triple effect tanks, in an effect tank top, be provided with charging aperture, at an effect tank, two effect tanks and triple effect tank, be respectively equipped with the first steam jacket, the second steam jacket and the 3rd steam jacket outward, the steam inlet of the second steam jacket is connected with the venthole of an effect tank top, and the steam inlet of the 3rd steam jacket is connected with the venthole of two effect tank tops; It is characterized in that also comprising heat exchanger, pans and steam jet pump, described feed tube is by described heat exchanger and described feeding inlet; The steam (vapor) outlet of described the first steam jacket and the second steam jacket communicates with described pans by pipeline; The steam (vapor) outlet of described the 3rd steam jacket communicates with the thermal source input of described heat exchanger, and the thermal source output of described heat exchanger communicates with described pans; Described intervalve bottom has condensation-water drain, outside has insulation jacket; Described steam jet pump, its import is connected with described steam supply house steward, its extraction opening is connected with pans, and its steam drain is connected with the steam inlet of the first steam jacket.
Caprolactam solution can carry out three step evaporation and concentration at an effect tank, two effect tanks, triple effect tank, and efficiency is higher; From effect tank venthole steam out, enter the second steam jacket for its heat supply, from two effect tank ventholes steam out, enter the 3rd steam jacket for its heat supply.From the second steam jacket and the 3rd steam jacket steam (vapor) outlet afterheat steam out, enter in pans and store, when passing through steam jet pump, steam supply house steward initial steam out can produce negative pressure, negative pressure can be by the afterheat steam in pans also suction to steam jet pump, both are the first steam jacket steam supply jointly after mixing also supercharging, form thus effectively circulation, steam has just obtained good recycling like this, on the other hand, the steam of discharging from the 3rd steam jacket is heat exchanger heat supply, give the process that enters the preheating of caprolactam solution between triple effect evaporator, to improve the temperature of caprolactam solution, improve thickening efficiency, from exchanger heat source output terminal steam and condensed water out, enter pans, steam can be utilized, condensed water can pass through condensation-water drain centralized collection.
The triple effect evaporation system of the production of polyester enterprise-specific that the utility model is designed, its advantage is compared with prior art: 1, thickening efficiency is high; 2, can effectively utilize afterheat steam; 3, energy-saving effect is better.
