Abstract
The utility model discloses an alkaline water settlement trough for producing 2,5-dimethyl-2,5-hexanediol. The alkaline water settlement trough comprises a settlement trough body which is connected with a first alkaline liquid discharging valve; the other end of the first alkaline liquid discharging valve is connected with an n-shaped device; the other end of the n-shaped device is connected with a second alkaline liquid discharging valve. Compared with the prior art, the alkaline water settlement trough for producing 2,5-dimethyl-2,5-hexanediol, which is disclosed by the utility model, has the advantages that organic solvents and byproducts cannot be discharged along with the discharging of alkaline liquid, and the separating effect is extremely good.
Description
Technical field
The utility model relates to a kind of production 2,5-dimethyl-2, the buck subsider of 5-hexylene glycol.
Background technology
Produce 2,5-dimethyl-2, in the technique of 5-hexylene glycol, if reclaim potassium hydroxide, recycle employing buck subsider, owing to from ethynylation still potassium hydroxide being out 30% the aqueous solution, and containing part organic solvent and accessory substance.Existing buck subsider organic matter will be drained with alkali lye layer.
Summary of the invention
The purpose of this utility model is just to provide a kind of production 2,5-dimethyl-2, and the buck subsider of 5-hexylene glycol, this produces 2,5-dimethyl-2, and buck subsider organic solvent and the accessory substance of 5-hexylene glycol can not discharged with alkali lye, have good separating effect.
The technical solution of the utility model is: a kind of production 2,5-dimethyl-2, the buck subsider of 5-hexylene glycol, comprise subsider body, this subsider body is connected with alkali lye the first blow-off valve, the described alkali lye first blow-off valve other end connects a N-shaped device, and this N-shaped device other end connects alkali lye the second blow-off valve.
As preferably, described N-shaped device is a N-shaped pipeline, and N-shaped duct height is 500mm.
Compared with prior art, the beneficial effects of the utility model are: owing to utilizing the water-fast feature of organic solvent and accessory substance, therefore N-shaped device and alkali lye the second blow-off valve are installed in storage tank exit, like this by the potassium hydroxide aqueous solution layering of standing rear organic solvent and accessory substance and 30%, during discharge, organic solvent and accessory substance remain at N-shaped device height and can not drain with alkali lye layer, therefore by discharging the potassium hydroxide aqueous solution of lower floor, recycle, the organic solvent on upper strata reclaims and uses, thereby reaches separated effect.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of prior art of the present utility model.
The specific embodiment
Below the utility model is described in further detail.
N-shaped device 6 is a N-shaped pipeline, and N-shaped duct height is 500mm.
The production 2 of the prior art shown in Fig. 2,5-dimethyl-2, the buck subsider of 5-hexylene glycol, comprise subsider body 1, the in-built liquid of subsider body 1 upper strata after sedimentation is organic matter liquid level 2, and lower floor is potassium hydroxide solution layer 3, and this subsider body 1 is connected with alkali lye the first blow-off valve 4.
Above-mentioned embodiment is only as explanation of the present utility model and unrestricted; the utility model protection domain also should comprise those apparent conversions to those skilled in the art, conversion, variation or substitute; and in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make various variations.
Claims (2)
1. produce 2,5-dimethyl-2, the buck subsider of 5-hexylene glycol for one kind, comprise subsider body, this subsider body is connected with alkali lye the first blow-off valve, it is characterized in that: the described alkali lye first blow-off valve other end connects a N-shaped device, and this N-shaped device other end connects alkali lye the second blow-off valve.
2. production 2 according to claim 1,5-dimethyl-2, the buck subsider of 5-hexylene glycol, is characterized in that: described N-shaped device is a N-shaped pipeline, and N-shaped duct height is 500mm.
