Most of acid separating devices commonly used at present are pipe-groove type acid separators, which utilize a plurality of larger chute to balance the liquid level of acid absorption so as to ensure the uniformity of acid separation, and the following problems mainly exist in the production and use processes: 1. the equipment has large volume, heavy mass and complex structure, the acid separation branch pipe is buried in the filler to easily receive corrosion of absorbed acid, and the workload of installation and maintenance is large; 2. the equipment has large volume, heavy mass and complex structure, the acid separation branch pipe is buried in the filler to easily receive corrosion of absorbed acid, and the workload of installation and maintenance is large; 3. the equipment has large volume, heavy mass and complex structure, the acid separation branch pipe is buried in the filler to easily receive corrosion of absorbed acid, and the workload of installation and maintenance is large.
Later through improving, adopted tubular acid distributor, overcome foretell defect, as patent publication No. CN205099361U discloses a tubular acid distributor, including advancing sour pipe, divide sour house steward and a plurality of branch sour pipes, divide sour branch pipe symmetry to establish and form a circular face in the both sides that divide sour house steward, divide sour branch pipe to equipartition to be equipped with a plurality of sour nozzles, all divide the import and the export of sour nozzle all to keep on same horizontal plane, its characterized in that, the inner wall that divides sour nozzle is equipped with downwardly extending's spiral. Although the technical scheme solves the technical problems, the tubular acid distributor has another problem that the acid inlet pipe and the acid distributing main pipe are vertically downward, the flow is large, the acid dropping point of the acid distributing main pipe is easily damaged due to long-term flushing, and vortex is easily generated to cause uneven acid outlet.
Disclosure of Invention
Based on the problems, the utility model aims to provide an acid separating device which solves the problems that an existing acid separating main pipe is easy to damage and acid is not uniform.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the acid distributing device comprises an acid inlet pipe and an acid header pipe connected with the acid inlet pipe, wherein the acid header pipe is connected with the acid header pipe through an acid falling pipe, a plurality of acid distributing branch pipes are connected to the acid header pipe, a plurality of acid distributing holes are formed in the acid distributing branch pipes, a slow flow device is arranged in the acid falling header pipe, and the slow flow device consists of a left slow flow block and a right slow flow block.
Furthermore, the number of the acid dropping pipes and the acid distributing main pipes is three.
Further, the left slow flow block and the right slow flow block form an S-shaped channel.
Preferably, the cross sections of the left slow flow block and the right slow flow block are triangular.
Preferably, the left slow flow block and the right slow flow block are both made of corrosion-resistant special alloy.
In summary, the utility model has the following advantages: by arranging the slow flow device, the impact of excessive flow of sulfuric acid on the acid separating main pipe is reduced, the uniform slow flow of sulfuric acid in the acid dropping pipe and the uniform average quantity of acid dropping points are ensured, and the acid separating effect and the absorption rate are further improved.
