Abstract

The utility model discloses a pickling circulation system comprising a pickling tank, a pickling pump, a pickling pump outlet pipe and a pickling tank liquid return pipe, wherein an inclined filter screen is arranged between the pickling tank and an outlet of the pickling tank liquid return pipe. By adopting the pickling circulation system, impurities and dirt of a dead angle inside the pipeline can be effectively cleaned; the dirt of large particles in returned liquid is cleaned; the blocking to the pipeline is avoided; the unnecessary consumption of pickling solution is avoided; the pickling time is saved; and the pickling efficiency is improved.

Description

The pickling recycle system

Technical field

The utility model relates to a kind of chemically-cleaning device, particularly a kind of pickling recycle system.

Background technology

The pipe pickling method is a lot, and the constructional method that take present working-yard has Dipping process and cycle pickling.Dipping process is to clean in scavenging solution segmented after the pipeline decomposition, owing to also will pipeline being carried out field weld after washing, can cause secondary pollution in pipeline.The pipeline cycle pickling is divided into online cycle pickling and line outer circulation pickling.Wherein online cycle pickling because of its good pickling effect, is generally adopted, and becomes the main method of pipe pickling, and the pipeline that installs is connected and composed the loop with flexible pipe or steel pipe, with sour pump, acid solution is squeezed in pipeline and is circulated.Pickle solution flows in pipeline, impurity acid in pipeline can be washed off, alleviates the burden of oil flushing; Tubing system can one-step installation put in place, and most pipelines need not dismantled, and can save many pipeline connecting fittings, reduces construction cost, reduces simultaneously leakage point, increases the stability of system works; Online cycle pickling can reduce the operations such as dismounting, handling, secondary installing, shortens construction period, reduces labour intensity; The pickler volume is little, and is simple for production, flexibly, moves at any time, meets the large characteristics of site operation mobility, reduces simultaneously cost of manufacture.

Circulating pickling device comprises pickling tank, acid picking pump and acid picking pump outlet pipe and pickling tank liquid returning tube.In prior art, only at acid picking pump outlet pipe place, outlet valve is set, starts acid picking pump when needing pickling, open outlet valve and circulate; Existing pickler pickling is returned larger dirt in liquid, entering pickle solution can not comparatively fast dissolve, and affects the circulation of pickling, reduces working efficiency.

Therefore, need a kind of circulating pickling device, effectively remove impurity and the dirt at dead angle in pipeline, simultaneously, the larger dirt of particle can in time be removed, improve the efficient of pickling.Summary of the invention

In view of this, the purpose of this utility model is to provide a kind of pickling recycle system, effectively removes impurity and the dirt at dead angle in pipeline, simultaneously, the larger dirt of particle can in time be removed, and improves the efficient of pickling.

The pickling recycle system of the present utility model comprises pickling tank, acid picking pump, acid picking pump outlet pipe and pickling tank liquid returning tube, is provided with the filtering net of inclination between the outlet of described pickling tank and pickling tank liquid returning tube.

Described acid picking pump outlet conduit is communicated with the liquid-inlet pipe entrance end and the drain pipe exit end that need the pickling pipeline by valve I and valve II respectively; Described pickling tank back liquid pipeline needs the liquid-inlet pipe entrance end of pickling pipeline and drain pipe exit end to be communicated with by valve III and valve IV respectively.

The described solidifying valve of connecting bend low spot setting that needs the pickling pipeline;

Described pickling tank bottom arranges blow-off pipe, and wash water valve is set on blow-off pipe;

The function of described valve I and valve II is realized by a T-valve; The function of valve III and valve IV is realized by a T-valve.

The beneficial effects of the utility model are: the pickling recycle system of the present utility model, can effectively remove impurity and the dirt at dead angle in pipeline, and remove the dirt of larger particles in returning liquid, avoid pipeline is formed and stop up, and avoid the consumption acids washing lotion that there is no need, save pickling time, improve the efficient of pickling.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further described.

Accompanying drawing is structural representation of the present utility model.

Embodiment

Accompanying drawing is structural representation of the present utility model, as shown in the figure: the pickling recycle system of the present embodiment, comprise pickling tank 1, acid picking pump 11, acid picking pump outlet pipe 9 and pickling tank liquid returning tube 2, be provided with the filtering net 7 of inclination between the outlet of described pickling tank and pickling tank liquid returning tube, as shown in the figure, filtering net 7 is supported in the upper opening of pickling tank by bracing frame 8, the macrobead dirt is by filtering net 7 tops outflows, and pickle solution enters pickling tank 1 by filtering net 7; Described acid picking pump outlet pipe 9 is communicated with the liquid-inlet pipe entrance end and the drain pipe exit end that need pickling pipeline 7 by valve I 5 and valve II 6 respectively; Described pickling tank liquid returning tube 2 is communicated with the liquid-inlet pipe entrance end and the drain pipe exit end that need the pickling pipeline by valve III 3 and valve IV 4 respectively; Need the connecting bend low spot setting of pickling pipeline 7 to fall to coagulate valve 8; Pickling tank 1 bottom arranges blow-off pipe, and wash water valve 10 is set on blow-off pipe; Can make the scavenging solution bidirectional circulating, effectively remove impurity and the dirt at dead angle in pipeline, and remove the dirt of larger particles in returning liquid, avoid pipeline is formed and stop up, and avoid the consumption acids washing lotion that there is no need, save pickling time, improve the efficient of pickling; Need the connecting bend low spot setting of pickling pipeline to fall to coagulate valve, can get rid of foreign material and the dirt of piling up in cleaning process or after cleaning; The pickling tank bottom arranges wash water valve, can in time discharge dirt and the foreign material of deposition, is beneficial to carrying out smoothly of wash cycles; Switching valve is T-valve, saves cost, simplifies the operation, and raises the efficiency.

The function of valve I 5 and valve II 6 is realized by a T-valve; The function of valve III 3 and valve IV 4 is realized by a T-valve, can further save cost, simplifies the operation, and raises the efficiency.

Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
