Description
Technical field
The utility model belongs to chemical field, and in particular to a kind of improved liquefied gas alkaline mud injection soul water stripper system
System.
Background technology
Soul water stripper is generally used for handling the acid water of each process unit discharge of oil plant, is contained with removing in acid water
The polluted medias such as some hydrogen sulfide, ammonia.The sulfide hydrogen and the sour gas of ammonia being stripped off deliver to sulfur recovery facility life
Sulphur is produced, so as to meet environmental protection requirement.Purified water after processing is as process waters such as crude oil electric desalting, each device water fillings
Reuse, can reach reduces full factory's water consumption, and reduces the purpose of quantity of wastewater effluent.Existing liquefied gas alkaline mud injects acid water
It is disadvantageous in that existing for stripping Tower System：Liquefied gas alkaline mud is directly separately injected into soul water stripper, and it exists with acid water
Enter unmixed before tower, just mix after entering tower with acid water, exist and mix the problem of uneven；Liquefied gas alkaline mud is by sewage stripping
More from the independent perforate injection in the middle part of tower body during tower, remaining time of the one side liquefied gas alkaline mud in tower is short, with acid water not
It is sufficiently mixed, it is impossible to farthest increase ammonia and hydrogen sulfide discharge rate, be on the other hand not easy to being not provided with middle part before
The note alkali technological transformation (could be transformed after the stopping production that need to stop) of the soul water stripper in note alkali hole.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of improved liquefied gas alkaline mud injection sewage stripping
Tower System, it can effectively overcome above-mentioned the deficiencies in the prior art.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of improved liquefied gas alkaline mud injection is acid
Water stripper system, it includes stripper and the surge tank for depositing liquefied gas alkaline mud, the bottom of the stripper are provided with
Steam inlet and treated water outlet, the steam inlet and steam supply pipeline connection, the treated water outlet and purification water delivery pipe
Road is connected, and liquid-inlet and gas outlet are provided with the top of the stripper, and the liquid-inlet connects with feed liquor supervisor, institute
State and multiple feed liquor branch pipes are provided with feed liquor supervisor, the feed liquor supervisor carrys out liquid pipeline with the acid water of plant area and connected, the vapour
Body outlet is sequentially communicated cooler and sour gas liquid separation tank by pipeline, and the sour gas liquid separation tank top is provided with sour gas row
Outlet, the bottom of the sour gas liquid separation tank are provided with the liquefied gas alkaline mud row of acid water refluxing opening, the surge tank and plant area
Go out pipeline connection, by the import of pipeline communication alkaline residue pump, the outlet of the alkaline residue pump passes through pipeline for the bottom of the surge tank
Connected with a feed liquor branch pipe on feed liquor supervisor, the acid water refluxing opening passes through on pipeline and feed liquor supervisor
Another feed liquor branch pipe connects, and acid water injects the stripper, the buffering with liquefied gas alkaline mud after feed liquor supervisor mixes
The regulating valve for adjusting alkaline residue injection feed liquor main conduit flow is provided with pipeline between tank and feed liquor supervisor.Regulating valve
The ratio of alkaline residue and acid water mixing is adjusted, can prevent alkaline residue surplus from causing hydrogen sulfide in acid water to be changed into vulcanized sodium or sulphur hydrogen
Change sodium and reduce the content of hydrogen sulfide in sour gas.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, being additionally provided with the surge tank prevents the too low steam for causing liquefied gas alkaline mud to crystallize of environment temperature from entering
Mouth and steam (vapor) outlet.After setting steam inlet and steam (vapor) outlet, can be passed through steam heating when ambient temperatures are low prevents alkaline residue knot
Brilliant plugging, or be passed through steam after alkaline residue pipe plugging by crystallization and dredge the pipeline that is blocked.
Further, the cooler is air cooler.The cost performance of air cooler is higher, and the vapour that can discharge stripper obtains cold
But, water recovery is water, is divided into sour gas and return acid water in acid water liquid separation tank.
Further, the evacuated tube for being easy to it to clean and overhaul is provided with the top of the stripper, is set in the evacuated tube
It is equipped with stop valve.During cleaning or before maintenance, evacuated tube is opened, to being taken a breath in stripper.
Compared with prior art, the beneficial effects of the utility model are：Liquefied gas alkaline mud is with acid water in feed liquor supervisor
Tower body is injected by the top of stripper again after mixing, therefore alkaline residue has mixed with acid water before tower body is injected, relative to tradition
Just mixed in tower body, its is more efficient, at the same its in top of tower be infused in retained in tower body time length, integrate
Effect preferably improve the extracting rate of hydrogen sulfide and ammonia in acid water；Middle and upper part alkaline residue is not separately provided for traditional
For the stripping tower of inlet, when carrying out the transformation of alkaline residue injection technology, the utility model has clear advantage, can not parking be
It can access liquefied gas alkaline mud filling line (coming with branch pipe access point in traditional acid water water influent pipeline).
