Description
Technical field
The utility model relates to the technical fields of carbide acetylene method production vinyl chloride, specifically slow down vinyl chloride low boiling
The device of point rectifying column autohemagglutination blocking.
Background technique
Currently, domestic PVC industry is mainly based on carbide acetylene method synthesis vinyl chloride thereof, wherein VCM synthesis
It is intermediate extremely important production link.In process of production, vinyl chloride autohemagglutination can occur often for vinyl chloride low boiling point rectifying column
Phenomenon will gradually block the tower tray of rectifying column with the progress of production, once blocking is serious, low tower is just unable to control and just
Often operation, seriously destroys production process, extreme influence polyvinyl chloride product quality, or even product transformation occur, causes larger warp
Ji loss.In the past, autohemagglutination blockage problem can often occur in vinyl chloride low boiling point rectifying column, and sudden very strong, give vinyl chloride
Normal production causes very big puzzlement.
Utility model content
In order to overcome the problems, such as that autohemagglutination blocking can often occur in vinyl chloride low boiling point rectifying column, the utility model, which provides, to be subtracted
The device of slow vinyl chloride low boiling point rectifying column autohemagglutination blocking.The device passes through polymerization inhibitor basin and polymerization inhibitor charge pump to low boiling point
Rectifying column conveys polymerization inhibitor, solves vinyl chloride low boiling point rectifying column and the technical issues of autohemagglutination blocking often occurs.
The utility model solves scheme used by technical problem:
Polymerization inhibitor basin is connect by the pipeline equipped with polymerization inhibitor charge pump inlet valve with polymerization inhibitor charge pump, polymerization inhibitor storage
Counterbalance valve is installed on the pipeline exported on the upside of tank, is added by the pipeline that polymerization inhibitor charge pump and counterbalance valve export by polymerization inhibitor
Through being conveyed to low boiling point rectifying column, polymerization inhibitor charging by check (non-return) valve and low boiling point rectifying column polymerization inhibitor inlet valve after material pump discharge valve
Another pipeline of pump is also conveyed to low boiling point rectifying column via runic list slot.
Good effect, the utility model pass through increase compared with prior art and are continuously added to polymerization inhibitor to low boiling point rectifying column
Process units, slow down low boiling point rectifying column autohemagglutination blocking, can run steadily in the long term, ensure that vinyl chloride high yield is steady
It produces.It is suitable to be used as the device for slowing down the blocking of vinyl chloride low boiling point rectifying column autohemagglutination.
Detailed description of the invention
Fig. 1 is utility model device structure configuration diagram.
In figure: 1. polymerization inhibitor basins, 2. polymerization inhibitor charge pump inlet valves, 3. polymerization inhibitor charge pumps, 4. runic list slots, 5. back
Pressure valve, 6. polymerization inhibitor charge pump outlet valves, 7. check (non-return) valves, 8. low boiling point rectifying column polymerization inhibitor inlet valves, 9. low boiling point rectifying columns.
Specific embodiment
Embodiment:
Polymerization inhibitor basin 1 is connect by the pipeline equipped with polymerization inhibitor charge pump inlet valve 2 with polymerization inhibitor charge pump 3, is inhibited
Counterbalance valve 5 is installed on the pipeline exported on the upside of agent basin, the pipeline exported by polymerization inhibitor charge pump and counterbalance valve is by resistance
Through being conveyed to low boiling point rectifying column 9 by check (non-return) valve 7 and low boiling point rectifying column polymerization inhibitor inlet valve 8 after poly- agent charge pump outlet valve 6,
Another pipeline of polymerization inhibitor charge pump is also conveyed to low boiling point rectifying column via runic list slot 4.
The liquid feeding higher boiling rectifying column of low boiling point rectifying column lower part, further rectifying, and the gaseous state of the output on top
Substance is sent into compressor and is compressed.
The polymerization inhibitor is liquid.
The substance of the rectifying is vinyl chloride.
The polymerization inhibitor charge pump uses plunger type metering pump.
The course of work:
A kind of liquid polymerization inhibitor is selected, is continuously added in vinyl chloride low boiling point rectifying column by polymerization inhibitor charge pump.Liquid
Polymerization inhibitor is stored in a canister, enters polymerization inhibitor charging pump intake by polymerization inhibitor charge pump inlet valve by bottom nozzles,
It pressurizes through charge pump, it, will in low boiling point rectifying column charging inlet by pump discharge through polymerization inhibitor charge pump outlet valve and check (non-return) valve
Polymerization inhibitor is added in rectifying column.It is equipped with counterbalance valve in pump discharge, when hypertonia, counterbalance valve is opened, and polymerization inhibitor flows back to basin,
To guarantee output pressure safety.
Operating method:
(1) polymerization inhibitor is filled into basin.
(2) polymerization inhibitor charge pump inlet valve is opened.
(3) start polymerization inhibitor charge pump.
(4) after pressure rises, counterbalance valve is adjusted to certain pressure, low boiling point essence can be added in polymerization inhibitor enough
It evaporates in tower.
(5) charge pump outlet valve is opened.
(6) low boiling point rectifying column polymerization inhibitor inlet valve is opened.
In this way, liquid polymerization inhibitor can keep uninterruptedly being added in low boiling point rectifying column, pass through polymerization inhibitor
Inhibition slows down the blocking of low boiling point rectifying column autohemagglutination, can continuous and steady operation.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims.
