Abstract
The invention discloses a device for separating and collecting low-molecular-weight resin. The device comprises a reactor and a packed tower which are communicated with each other through a tower column pipeline, wherein a gasified water outlet pipeline is arranged at the top of the packed tower, a spray head is arranged above fillings in the packed tower and is connected with an alcohol inlet pipeline, and a storage container is arranged at the lower part of the packed tower. After the gasified water and the low-molecular-weight resin in the reactor enter the packed tower, the low-molecular-weight resin contacts with alcohol substances ejected from the spray head in the packed tower and is dissolved by the alcohol substances, so that the low-molecular-weight resin is separated and is prevented from being adhered to a tower column and the pipeline, and the tower column or the pipeline cannot be blocked.
Description
Technical field
The present invention relates to negative pressure polymerization technique field, especially relate to a kind of device for separating of collecting low-molecular-weight resin.
Background technology
Domestic traditional negative pressure polymerization stage is all to utilize vacuum pipeline to form negative pressure to reactor, and the path one that synthetic water is discharged is to discharge by destilling tower and vacuum pipeline, the 2nd, directly by vacuum pipeline, discharge.
As shown in Figure 2, the low-molecular-weight resin forming in the reactor 1 of vacuum can be attached in the king-post and pipeline of packed tower 3, cleaning work is very difficult, bring huge workload to plant maintenance and maintenance, greatly reduce production efficiency, even cause the obstruction of king-post or pipeline, thereby affect product quality.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention is to provide a kind of device for separating of collecting low-molecular-weight resin, and it separates low-molecular-weight resin in packed tower, prevents that low-molecular-weight resin is attached on king-post and pipeline.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of device for separating of collecting low-molecular-weight resin, comprise reactor and packed tower, between described reactor and packed tower, by king-post pipeline, be connected, described packed tower top is provided with gasification outlet conduit, the inherent filler of described packed tower top is provided with spray head, and spray head is connected with alcohols inlet pipeline, and described packed tower bottom is provided with storage container.
Further, the hole that described king-post pipeline is connected with packed tower is below the filler of packed tower.
Described storage container bottom is provided with discharge line.
The present invention compared with prior art, have the following advantages: after the gasified water in reactor and low-molecular-weight resin enter in packed tower, spray head ejection alcohols material in packed tower, low-molecular-weight resin contacts with the alcohols material of ejection, low-molecular-weight resin can be dissolved by alcohols material, reach the object of separate low molecular resin, prevent that low-molecular-weight resin is attached on king-post and pipeline, avoid causing king-post or line clogging phenomenon.
Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is apparatus of the present invention structural representation.
Fig. 2 is existing negative pressure polymerization pipeline system architecture schematic diagram.
In figure: 1. reactor, 2. storage container, 3. packed tower, 4. king-post pipeline, 5. gasification outlet conduit, 6. discharge line, 7. spray head, 8. alcohols inlet pipeline.
The specific embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention.
As shown in Figure 1, should be for separating of the device of collecting low-molecular-weight resin, comprise reactor 1, packed tower 3, storage container 2, spray head 7, wherein, the interior middle part of packed tower 3 is provided with filler, between hole on the packed tower of reactor 1 and filler below, by king-post pipeline 4, be connected, packed tower 3 tops are connected with gasification outlet conduit 5; The inherent filler of packed tower 3 top is provided with spray head 7, and spray head 7 is connected with alcohols inlet pipeline 8; Packed tower 3 bottoms are provided with storage container 2, are convenient to collect the low-molecular-weight resin of separating.
In storage container 2 bottoms, be provided with discharge line 6, and on discharge line 6, valve be installed, when storage container is collected more low-molecular-weight resin, Open valve is discharged the low-molecular-weight resin of collecting by discharge line.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
