Description
Technical field
The utility model belongs to chemical mechanical equipment field, is specifically related to a kind of device adopting chemical process to clean phosphoric acid pipeline scale.
Background technology
At present, phosphorus chemical industry is more and more many, and the grade of phosphate rock resource is more and more lower.With low-grade phosphate ore stone produce scaling in process phosphoric acid, pipeline scale can be more serious, the method of labor cleaning is relied on to be can not meet production system far away to need all the time, phosphoric acid production device perplex by pipeline scale, badly influence the consecutive production of whole device, cause phosphoric acid can not meet the needs of whole phosphatic compound fertilizer device.Adopt the method for labor cleaning, in concrete operating process, there are certain Hazard Factor, also can damage pipeline and equipment.
Summary of the invention
The purpose of this utility model is for above problem, provides a kind of device adopting chemical process to clean phosphoric acid pipeline scale, effectively can be removed the dirt in pipeline by dilute sulphuric acid.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of device adopting chemical process to clean phosphoric acid pipeline scale, comprise sulfuric acid thinning tank, sulfuric acid hold-up vessel and water tank is provided with above it, inner cycle channel and outer circulation passage is provided with outside sulfuric acid thinning tank, inner cycle channel is provided with recycle pump, and outer circulation passage adopts pipeline to connect discharge port, interchanger, transferpump, the pipeline to be cleaned of sulfuric acid thinning tank successively, is finally connected to the discharge port of sulfuric acid thinning tank.
Described interchanger is graphite heat exchanger, and heat transferring medium is low-pressure steam.By low-pressure steam, indirect heating is carried out to the dilute sulphuric acid in pipeline, after making temperature reach 55-65 DEG C, efficiently can remove ducted dirt to be cleaned.
Described sulfuric acid thinning tank inside is also provided with whipping appts, can ensure that sulfuric acid can dilute evenly, and the dilute sulphuric acid returned from outer circulation passage also can carry out again mixing preparation after recycle.
The utility model adopts said structure design, first diluting concentrated sulfuric acid is become the dilute sulphuric acid of 5-8%, mixing preparation can be carried out by the whipping appts of sulfuric acid thinning tank inside and inner cycle channel, stir, then after interchanger heating, adopt transferpump to squeeze in pipeline to be cleaned the material stirred and carry out scale removal, finally be recovered to sulfuric acid thinning tank, complete cleaning.The utility model adopts hot sulphuric acid soln to carry out scale removal, potassium, sodium class phosphoric acid salt and silicofluoride can be made to be rapidly dissolved in dilute sulphuric acid, reach cleaning effect.And dilute sulphuric acid can carry out circulation repeatedly, cleaning effect is good, safety and environmental protection, and this apparatus structure is simple, reasonable in design, easy to use, is applicable to promoting.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As shown in Figure 1, a kind of device adopting chemical process to clean phosphoric acid pipeline scale, comprise sulfuric acid thinning tank 1, sulfuric acid hold-up vessel 2 and water tank 3 is provided with above it, inner cycle channel 4 and outer circulation passage 5 is provided with outside sulfuric acid thinning tank 1, inner cycle channel 4 is provided with recycle pump 41, outer circulation passage 5 adopts pipeline to connect discharge port 11, interchanger 51, transferpump 52, the pipeline to be cleaned 53 of sulfuric acid thinning tank 1 successively, is finally connected to the discharge port 12 of sulfuric acid thinning tank 1.
Described interchanger 51 is graphite heat exchanger, and heat transferring medium is low-pressure steam.
Described sulfuric acid thinning tank 1 inside is also provided with whipping appts.
When using the utility model, sulfuric acid hold-up vessel 2 deposits the vitriol oil that mass concentration is 98%, it is diluted in sulfuric acid thinning tank 1 dilute sulphuric acid of 5-8%, heat exchange is carried out again through graphite heat exchanger and low-pressure steam, temperature to dilution heat of sulfuric acid is increased to 55-65 DEG C, by transferpump dilution heat of sulfuric acid is driven in pipeline 53 to be cleaned and cleans, iterative cycles, the effect removing dirt fast can be reached.
