Description
Technical field
The utility model relates to waste acid treatment technical field, in particular to a kind of removal acid purification system feeding line crystallization
The circulatory system.
Background technique
Acid purification system is mainly handled the spent acid that pickling line discharges, and produces regenerated acid and iron powder.It is chemically reacted
It is carried out in acid regeneration unit roaster.Wherein spent acid enters in roaster by feeding line, carries out spray roasting technique.?
Due to containing silicide and other impurities in spent acid in production process, feeding line caliber is be easy to cause to become smaller.Eventually lead to machine
Group processing spent acid ability decline, influences unit processing spent acid ability, to influence the production of pickling line.
In order to guarantee that unit production capacity meets the positive common acid demand and guarantee spent acid zero-emission of pickling line, it is ensured that equipment
The stability of operation must just solve these problems.
Utility model content
The purpose of this utility model is just to provide one kind and becomes smaller for acid purification system feeding line caliber, and unit handles energy
The problems such as power declines takes and increases alkali soluble liquid storage tank using downtime to the corresponding alkali cleaning of feeding line progress, thus remove into
The silicide and other impurities of expects pipe line, guarantee the flux of feeding line, to improve the removal acid regeneration of unit processing capacity
The circulatory system of system feeding pipeline crystallization.
The solution of the utility model is such that
A kind of circulatory system of removal acid purification system feeding line crystallization, including roaster, preconcentrator, preconcentrator
Circulating pump, roaster feed pump, feeding line, spray gun further include alkali soluble liquid storage tank and alkali cleaning pipeline, alkali cleaning pipeline one end
It is connected to alkali soluble liquid storage tank, the other end is provided with the Active Interface connecting with the spout of spray gun；The alkali soluble liquid storage tank passes through pipeline
It is connected to preconcentrator；When being cleaned, the Active Interface of the alkali cleaning piping connection and the spout connection of spray gun, aqueous slkali
The sodium hydroxide solution that storage tank is equipped with flows into preconcentrator, and after roaster feeds pump startup, solution is delivered to feed pipe, spray
Rifle, the solution flowed out from the spout of spray gun send preconcentrator back to by alkali cleaning pipeline.
More specific technical solution further include: the alkali soluble liquid storage tank is located above preconcentrator, is self-possessed by solution and is flow automatically
Enter preconcentrator.
The utility model has the advantages that: by the impurity of the fully erased feeding line of above method energy, guarantee feeding line
Flux, guarantee acid regeneration unit treating capacity；Alkali cleaning is carried out to feeding line for acid regeneration unit productive prospecting per half a month, no
It needs because pipeline blocking replacement feeding line, had both saved equipment maintenance cost in this way and decreased labor intensity.
Detailed description of the invention
Fig. 1 is the system structure diagram of the utility model.
Appended drawing reference in figure are as follows: roaster 1, preconcentrator 2, pre-concentrator circulating pump 3, roaster feed pump 4, feed pipe
Line 5, newly-increased alkali cleaning pipe 6, alkali soluble liquid storage tank 7, valve 8, exhaust-valve 9.
Specific embodiment
As shown in Figure 1, including roaster 1, preconcentrator 2, pre-concentrator circulating pump 3, roaster feed pump 4, feed pipe
Line 5, spray gun 10, it is characterised in that: further include alkali soluble liquid storage tank 7 and alkali cleaning pipeline 6, described 6 one end of alkali cleaning pipeline is connected to alkali soluble
Liquid storage tank 7, the other end are provided with the Active Interface connecting with the spout of spray gun 10；The alkali soluble liquid storage tank 7 is connected by pipeline
To preconcentrator 2；When being cleaned, the spout connection of Active Interface and spray gun 10 that the alkali cleaning pipeline 6 connects, aqueous slkali
Storage tank 7 be equipped with sodium hydroxide solution flow into preconcentrator 2, roaster feed pump 4 starting after, by solution be delivered to first into
Expects pipe 5, spray gun 10, the solution flowed out from the spout of spray gun send preconcentrator 2 back to by alkali cleaning pipeline 6.Alkali soluble liquid storage tank 7 is located at
2 top of preconcentrator flows into preconcentrator 2 by solution self weight certainly.
Specific implementation process when the present embodiment is cleaned: the hydrogen that concentration is 10% or so is equipped in alkali soluble liquid storage tank 7
Sodium hydroxide solution 3t, the spout connection of the Active Interface that alkali cleaning pipeline 6 is connected and spray gun 10 are equipped in alkali soluble liquid storage tank 7
Sodium hydroxide solution, from flowing into preconcentrator 2, is heated to 90 DEG C or so by furnace gas by pipeline by sodium hydroxide solution.It opens
Dynamic pre-concentrator circulating pump 3, recycles in preconcentrator 2；Start roaster feed pump 4 simultaneously, solution is delivered to feed pipe
Line 5, the solution sprayed from spray gun 10 return in preconcentrator 2 by alkali cleaning pipeline 6, complete a clean cycle.
The silicide adhered in feeding line 5 and other impurities can be removed by being recycled 24 hours by pipeline, after the completion of cleaning
By exhaust-valve 9, aqueous slkali is emptied, cuts off alkali cleaning pipeline 6, state of resuming production.It can solve charging by operating above
The problem of pipeline caliber becomes smaller guarantees unit production capacity.
