Abstract
The utility model discloses a device for desorbing low boiling point material in polyether polyol, which comprises a storage tank; a stirrer is arranged in the storage tank, an inlet of a circulation tube is arranged at the top of the storage tank, an outlet of the circulation tube is arranged at the bottom of the storage tank; a circulating pump is arranged at the circulation tube; an extracting tank is connected with the circulation tube; an exhaust pipe is arranged at the top of the storage tank; and a spray head is arranged at the inlet of the circulation tube. The device is simple in structure, can fully desorb the low boiling point material in polyether polyol, so that the refined polyether polyol meeting requirements can be obtained.
Description
Technical field
The utility model relates to a kind of low-boiling point material separator, specifically a kind of device that removes low-boiling point material in the PPG.
Background technology
Usually can contain low-boiling point materials such as water in PPG, these low-boiling point materials can be dissolved in the PPG under normal conditions.PPG leaves in the hold-up tank, and for the PPG in the hold-up tank is made with extra care, the low-boiling point material evaporation that needs to be dissolved in the PPG removes.
The boiling point of PPG in the prior art, utilizes the boiling point difference of PPG and low-boiling point material to remove low-boiling point material in the PPG about 230 ℃.Usually adopt the discharge method of above hold-up tank, bleeding, when bleeding, in hold-up tank, inject PPG by circulating pump, because the agitator in the hold-up tank is ceaselessly in rotation, low-boiling point material in the hold-up tank in the PPG is evaporated out, exhaust tube by the hold-up tank top is discharged, and finishes the refining to PPG in the hold-up tank.In the prior art, because by injecting PPG in pipeline is directly in hold-up tank, the low-boiling point material evaporation effect is poor.Studies show that, under 120 ℃ of temperature through 6 hours after, to retain concentration be 0.08% to low-boiling point material in the PPG, can not satisfy the requirement of refining PPG.
Summary of the invention
In order to overcome the problem of the low-boiling point material evaporation effect difference that exists in the prior art, the purpose of this utility model provides a kind of device that removes low-boiling point material in the PPG, this apparatus structure is simple, can fully remove low-boiling point material in the PPG, obtain satisfactory refining PPG.
The purpose of this utility model is achieved through the following technical solutions:
A kind of device that removes low-boiling point material in the PPG comprises hold-up tank, is provided with agitator in hold-up tank, is provided with the import of circulating line at the hold-up tank top, is provided with the outlet of circulating line in the hold-up tank bottom; On circulating line, be provided with circulating pump; Extractor is connected with circulating line; Be provided with blast pipe at the hold-up tank top; It is characterized in that: the import department at circulating line is provided with sprinkler head.
In the utility model, described sprinkler head is and the suitable circle of hold-up tank cross sectional shape, is provided with one group of spray orifice on circular sprinkler head.
For not having impurity in the PPG that guarantees to enter sprinkler head, prevent to stop up spray orifice, on circulating line, be provided with screen pack.
For convenient system PPG in the hold-up tank is extracted in the extractor, on circulating line, be provided with circulation control valve; Be provided with the extraction control valve on the pipeline before extractor.
The utility model adopts sprinkler structure to guarantee to be scatter by the PPG that the circulating line import enters in the hold-up tank, the best is effective, compared with prior art, the utility model is simple in structure, can fully remove low-boiling point material in the PPG, obtain satisfactory refining PPG.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of device that removes low-boiling point material in the PPG described in the utility model, see Fig. 1, this device comprises hold-up tank 1, is provided with agitator 2 in hold-up tank 1, be provided with the import of circulating line 3 at hold-up tank 1 top, be provided with the outlet of circulating line 3 in hold-up tank 1 bottom; On circulating line 3, be provided with circulating pump 5; Extractor 7 is connected with circulating line 3; Be provided with blast pipe 8 at hold-up tank 1 top; Import department at circulating line 3 is provided with sprinkler head 6.Sprinkler head 6 is and the suitable circle of hold-up tank 1 cross sectional shape, is provided with one group of spray orifice on circular sprinkler head.
For not having impurity in the PPG that guarantees to enter sprinkler head, prevent to stop up spray orifice, on circulating line 3, be provided with screen pack 4.For convenient system PPG in the hold-up tank 1 is extracted in the extractor 7, on circulating line 3, be provided with circulation control valve 10; Be provided with on the pipeline before extractor 7 and extract control valve 11.
During refining, open the control valve 10 on the circulating line 3, extract control valve 11 and close.Circulating pump 5 work, PPG liquid in the hold-up tank is entered in the circulating line 3 by the outlet of circulating line 3 bottoms, flow to hold-up tank 1 top, and in hold-up tank 1, spray by circulating line 3, process screen pack 4 by one group of spray orifice that circular sprinkler head is provided with.Simultaneously, agitator 2 work, blast pipe 8 is in bleeds, and the low-boiling point material evaporation that then is dissolved in the PPG is removed from blast pipe 8.After refining is finished, as long as close control valve 10 on the circulating line 3, open and extract control valve 11 and get final product, the PPG after the refining enters in the extractor 7.
The utility model is simple in structure, and is easy to use, can fully remove low-boiling point material in the PPG, obtains satisfactory refining PPG.
