Description
Technical field
The invention belongs to chemical plant installations technical fields, and in particular to a kind of epoxychloropropane saponification column.
Background technology
At present in the production technology of epoxychloropropane, dichlorohydrin and milk of lime enter saponification column and carry out saponification,
The thick epoxychloropropane generated carries out condensation extraction by evaporator overhead condenser collection, and saponification waste-water squeezes into sudden strain of a muscle by saponification column bottoms pump
Steaming pot carries out recuperation of heat processing.Also there is side reaction during saponification, the milk of lime not reacted completely can absorb saponification
Carbon dioxide in liquid generates calcium carbonate.
Polylith column plate inside epoxychloropropane saponification column in the prior art, including saponification tower body and saponification column body, point
Not Wei upper layer column plate, the second column plate, third column plate, the 4th column plate ..., bottom column plate, further include saponification liquid level into
Expects pipe line, connects saponification liquid feeding vertical pipeline after saponification liquid horizontal feed pipeline, saponification liquid vertically into
Expects pipe line bottom nozzle connects saponification liquid horizontal flow pipeline.Since the direction of saponification liquid horizontal flow pipeline is horizontal
Direction, mobility is poor, and positioned at the top of upper layer column plate, closer from upper layer column plate, distance is less than 20cm, leads to calcium carbonate very
It is readily adsorbed on saponification liquid horizontal flow pipeline.In addition, calcium carbonate is also easier to be adsorbed on column plate.
With the passage of production time, the phenomenon that saponification liquid horizontal flow pipeline and column plate fouling, is increasingly severe,
It is excessive so as to cause saponification column pressure difference, affect the stable operation of saponification column.It needs to carry out pickling, Cai Nengbao to column plate, pipeline
Card production is smoothed out.And pickling will cause to stop, and not only delay production, and a large amount of manpower and materials is caused to be lost, and be produced into
This also rises therewith.
To sum up, it is badly in need of researching and developing a kind of reduction fouled condition, the epoxychloropropane saponification column to extend manufacture cycle at present.
Utility model content
The purpose of this utility model is to provide a kind of flowing time shortening saponification liquid in pipeline, reduces fouling shape
Condition, the epoxychloropropane saponification column to extend manufacture cycle.
Column plate inside epoxychloropropane saponification column described in the utility model, including saponification tower body and saponification column body, also
Including saponification liquid horizontal feed pipeline, saponification liquid vertical feed pipe is connected after saponification liquid horizontal feed pipeline
Line is not provided with upper layer column plate inside saponification column body, and column plate is followed successively by the second column plate, third column plate, the 4th tower from top to bottom
Plate ..., bottom column plate, the second column plate is set below saponification liquid feeding vertical pipeline.
Wherein：
The distance between the saponification liquid feeding vertical pipeline bottom nozzle and the second column plate are 30-60cm.
The saponification liquid horizontal feed pipeline connects static mixer.
The static mixer is connected with dichlorohydrin feeding line, milk of lime feeding line respectively.
The number of the column plate is 15-25 blocks.
The column plate outer surface sprays anticorrosive PTFE layer.It is preferred that after the column plate outer surface first connects sandblasting layer,
Anticorrosive PTFE layer is sprayed again.
Steam pipe line is set below the bottom column plate.
The beneficial effects of the utility model are as follows：
Saponification liquid horizontal flow pipeline in the prior art direction is horizontally oriented, and mobility is poor, increases soap
Change flowing time of the reaction solution in pipeline, leads to easy fouling.So the utility model is by saponification liquid horizontal flow pipeline
Remove, only retains saponification liquid horizontal feed pipeline and saponification liquid feeding vertical pipeline, avoid saponification liquid water
The phenomenon that flat bypass line easy fouling, reduces flowing time of the saponification liquid in pipeline, avoid in the short time, saponification
Milk of lime fouling in pipeline in reaction solution, the pipeline blockage caused by fouling also greatly reduce.
In addition, the second column plate is arranged in saponification liquid feeding vertical pipeline directly below, upper layer column plate is eliminated so that soap
The distribution for changing reaction solution is more uniform, while increasing activity space when operating personnel's maintenance.
Meanwhile the utility model also provides the column plate for preventing fouling.Because polytetrafluoroethylene (PTFE) friction coefficient is small, has and do not glue
Property, and polytetrafluoroethylene (PTFE) has the characteristic of acid-alkali-corrosive-resisting and scale inhibition, and anticorrosive PTFE layer is sprayed in column plate outer surface, greatly
Reduce scale formation greatly.And be fixedly connected with anticorrosive PTFE layer by sandblasting layer in column plate outer surface, make poly- four
Vinyl fluoride erosion resistant coating is combined more secured with column plate.In order to keep original production efficiency, after improvement the percent opening of column plate with change
Percent opening into preceding column plate is identical.Therefore, the fouled condition of column plate is substantially improved by spraying anticorrosive PTFE layer.
To sum up, the utility model shortens flowing time of the saponification liquid in pipeline, reduces fouled condition, simultaneously
The scale formation for also improving column plate reduces frequent pickling processes, extends the production cycle, greatly reduces and be produced into
This.
