Description
Technical field
The utility model relates to the technical field of carbide acetylene method production vinyl chloride, specially not parking replacement vinyl chloride is low
The device of boiling point rectifying column.
Background technique
In recent years, with the rapid development of chlor-alkali and PVC industry, considerable economic effect is created for place and enterprise
Benefit, and this economic benefit is inseparable with the continuous-stable of production.Vinyl chloride production is weight in chlor-alkali and PVC Chemical Manufacture chain
The ring wanted, its unexpected parking can break line balancing, chlor-alkali system chlorine yield be influenced, in order to which line balancing need to reduce production
Can, to cause certain economic loss, while because of loss of material and energy waste caused by driving and parking processing.In the past, vinyl chloride
Low boiling point rectifying column goes wrong, and vinyl chloride the whole series process units, which must stop, to be replaced, since burst and long-time are replaced,
It causes to normal production compared with havoc, while causing certain economic loss.For this purpose, we pass through process modification and innovation, make
Low tower can normally be replaced in the case where not parking, ensure that normal continuous production, low so as to avoid parking replacement
Production caused by tower destroys and lost revenue.
Utility model content
In order to realize it is not parking add materials, the utility model provides not parking replacement vinyl chloride low boiling point rectifying column
Device, the device solve not parking replacement essence by converting between low boiling point rectifying column and higher boiling rectifying column via isolating valve,
The technical issues of evaporating tower.
The utility model solves scheme used by technical problem:
Runic list slot is connect by low tower charging regulating valve and low boiling point rectifying column import isolating valve, with low boiling point rectifying column,
It is connect by the first connecting line isolating valve, upper end pipeline with low boiling point rectifying column in the lower part of low boiling point rectifying column, in low boiling point
Second connecting line isolating valve, is housed, via low boiling point rectifying column bottom on the pipeline connected between rectifying column and higher boiling rectifying column
The substance in portion is connect by storage tank and output pipe with higher boiling rectifying column, and lower higher boiling rectifying column is equipped on the pipeline of connection
Isolating valve, upper higher boiling rectifying column isolating valve, and into essence monome blanking pipeline isolating valve, higher boiling the top of the distillation column passes through pipeline
It connect with finished product condenser, is connect by finished product condensator outlet isolating valve, with essence monome storage tank in finished product condenser.
Good effect, the utility model compared with prior art, by piping connection and valve transfer, can freely be isolated
Vinyl chloride low boiling point rectifying column, at the same guarantee production can normal continuous operation, low boiling point rectifying column can replace normally, be avoided
Package unit parking and caused by economic loss.It is suitable for being used as the not parking device for replacing low boiling point rectifying column.

Specific embodiment
According to the figure, runic list slot 1 passes through low tower charging regulating valve 2 and low boiling point rectifying column import isolating valve, 8 and low boiling
Point rectifying column 3 connects, and passes through 7 upper end pipeline of the first connecting line isolating valve, and low boiling point rectifying in the lower part of low boiling point rectifying column
Tower connects, and the second connecting line isolating valve, 9 is housed on the pipeline connected between low boiling point rectifying column and higher boiling rectifying column 4,
It is connect by storage tank and output pipe with higher boiling rectifying column via the substance of low boiling point rectifier bottoms, on the pipeline of connection
Equipped with lower higher boiling rectifying column isolating valve, 10, upper higher boiling rectifying column isolating valve, 11 and into essence monome blanking pipeline isolating valve, 12,
Higher boiling the top of the distillation column is connect by pipeline with finished product condenser 5, passes through finished product condensator outlet in finished product condenser
Isolating valve, 13 is connect with essence monome storage tank 6.
By the control of isolating valve, it can be realized material and turn via between low boiling point rectifying column or higher boiling rectifying column
It changes, realizes not parking charging.
The course of work:
Crude monomer is input to low boiling point rectifying column by low tower charging regulating valve by runic list slot, by the material of rectifying column
It is conveyed to higher boiling rectifying column, again rectifying, the unqualified crude monomer after rectifying is condensed by condenser, then passes through lower liquid pipe
Sky essence monome storage tank is inputed to, to realize isolation replacement low boiling point rectifying column in not parking situation.
Operating method:
(1) it before low boiling point rectifying column is isolated, is ready to be capable of an empty essence monome storage tank of blanking.
(2) it can suitably be dropped to reduce the unqualified monomer of processing according to repair time and essence monome storage tank storage capacity
Low produce load.
(3) stop feeding to low boiling point rectifying column and higher boiling rectifying column, close low boiling point rectifying column pan feeding hand valve, finished product
Condenser baiting valve is closed, and low boiling point rectifying column is closed into high tower hand valve and higher boiling rectifying column pan feeding hand valve.Open communicating pipe
Valve, opens connection isolating valve, and opening removes essence monome slot valve.
(4) open low tower and feed regulating valve, flow is adjusted according to crude monomer tank liquor position, by crude monomer it is direct under expect it is smart single
In body slot, operation such as low boiling point rectifying column in the same direction feeds.Since thick slot pressure is 0.65MPa or so, essence monome storage pressure one
As be less than 0.2MPa, it is possible to smoothly by crude monomer force feed into essence monome storage tank.
In this way, production can keep continuous, while low boiling point rectifying column has been isolated, and can be carried out normal material processing and be gone forward side by side
Row replacement.
