Abstract
The utility model relates to a waste material processing system of spandex solvent. A neutralizing tank is additionally arranged mainly according to the higher acid value in waste liquid, a neutral reaction can be carried out by utilizing an acid-base neutralization theory, low-boiling point material can be then steamed out through a tray steaming tower, and high-boiling point material and salt can be dug out from the bottom part of the tray steaming tower; an ion exchanging tower is additionally arranged at the front part of a finished product outlet, and thus the electrolyte in organic solvent dimethylacetamide can be effectively reduced; a scrubber tower is additionally arranged on the tray steaming tower, and thus the damage to the human body and the influence to the environment due to the higher concentration of the dimethylacetamide during a salt digging process can be effectively reduced; and therefore, the waste material processing system disclosed by the utility model has the characteristics that the distribution is reasonable, the cost is saved, the environment is protected, and the like.
Description
Technical field
The utility model relates to a kind of waste disposal system, especially a kind of spandex solvent waste disposal system.
Background technology
Spandex is a kind of elastomeric weaving special fibre; Major part all adopts the dry method textile technology in the world at present; But must use this organic solvent of dimethylacetylamide in the dry method fabrication processes, but its health and environment to the people can make a big impact, and how to reduce the use amount and the discharge capacity of organic solvent; Not only be related to production cost, more relate to production environment.
Summary of the invention
The purpose of the utility model is not enough to prior art, solves in producing the spandex process dimethylacetylamide depletion of additive amount and discharge capacity greatly to problems such as ambient influnence are big, thereby designs a kind of spandex solvent waste disposal system.The technical scheme of the utility model is so to realize:
A kind of spandex solvent waste disposal system; Comprise dehydrating tower, rectifying column and finished product discharging opening; Between finished product discharging opening and rectifying column, be provided with ion exchange tower, rectifier bottoms is connected with extracting tower, neutralization chamber and dish in turn and steams tower, and said dish steams top of tower and is connected with an aeration tower.
As preferably, be provided with a vavuum pump between said dish steaming top of tower and the outlet.
As preferably, be provided with a vavuum pump between said extracting tower and the neutralization chamber.
As preferably, closely coil the steaming tower bottom and be provided with Wa Yankou.
The spandex solvent waste disposal system of the utility model design; Mainly higher according to acid number in the waste liquid, set up neutralization chamber, utilize the acid-base neutralization theory to carry out neutralization reaction; Steam tower through dish then the low boiling material is steamed, high boiler material and salt steam tower bottom from dish and dig out; Before the finished product discharging opening, set up ion exchange tower, effectively reduce electrolyte in the organic solvent dimethylacetylamide; Steam on the tower at dish and to have set up aeration tower, effectively reduce in digging the salt process because the higher injury that human body is produced of dimethylacetylamide concentration and to the influence of environment.Therefore very utility model have rationally distributed, practice thrift characteristics such as cost, protection environment.
Description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing,, do further bright specifically to the technical scheme of the utility model through embodiment.
Embodiment: with reference to accompanying drawing; A kind of spandex solvent waste disposal system comprises dehydrating tower 8, rectifying column 7 and finished product discharging opening 9, between finished product discharging opening 9 and rectifying column 7, is provided with ion exchange tower 5; Rectifying column 7 bottoms are connected with extracting tower 1, neutralization chamber 2 and dish in turn and steam tower 3; Be provided with a vavuum pump 6 between said extracting tower 1 and the neutralization chamber 2, dish steams tower 3 tops and is connected with an aeration tower 4, and nearly dish steaming tower 3 bottoms are provided with digs salt mouth 11.Dish steams between tower 3 tops and the outlet 10 and is provided with a vavuum pump 6.
In the course of work, behind dehydrating tower 8 and rectifying column 7, discharge that acid accounts for 5% the material at the bottom of rectifying column 7 towers, dimethylacetylamide accounts for 75%, and other is a high boiler material.Utilize vavuum pump to squeeze into further depickling in the extracting tower 1 in waste material earlier; The waste material of extracting tower 1 is squeezed in the neutralization chamber 2 then, adds 25%NaOH and carries out the acid-base neutralization reaction, and reacting rear material enters dish and steams in the tower 3; Under the effect of vavuum pump 6, distill, the low boiling material is steamed.After distillation finishes, open aeration tower 4, the dimethylacetylamide concentration that dish is steamed in the tower 3 drops to minimum.Operation back dimethylacetylamide electrolyte can rise in enclosed environment for a long time, and 9 places have set up ion exchange tower 5 at the finished product discharging opening, can improve the quality of dimethylacetylamide effectively.
Show through the production time; This waste disposal system can effectively reduce the ton silk consumption of dimethylacetylamide in product; The consumption of dimethylacetylamide was not 100kg/T before this device used, and used this device back to be 40kg/T, had improved plant environment significantly, had practiced thrift cost.
