Description
Technical field
The present invention relates to a kind of washing unit of phosphoric acid line of pipes, belong to chemical technology field.
Background technology
In the Wet-process Phosphoric Acid Production process, because the composition of Rock Phosphate (72Min BPL) is complicated, in sulfuric acid and Rock Phosphate (72Min BPL) reaction generation phosphoric acid, also generate a large amount of phosphogypsums, the impurity such as Sodium Silicofluoride, potassium silicofluoride and a large amount of metal oxides.Phosphoric acid in course of conveying because transport pipe is longer, temperature constantly reduces, the solubleness of each impurity in phosphoric acid constantly descends, these impurity will be separated out with solid-state form and are bonded on tube wall, along with the long-play of pipeline, various impurity are also more long-pending thicker on tube wall, and the latus rectum of pipeline constantly diminishes, the resistance but also the flow that have not only increased handling equipment are also more and more less, can not satisfy the normal need of production of each device.Enterprise is in order to solve the blockage problem of dirty confrontation line of pipes, generally to the design of phosphoric acid line of pipes the time adopts one to open a standby scheme, can when a pipeline stops up cleaning because of dirty matter, move for the standby pipe of acid tube with another root like this.In the prior art, when the phosphoric acid line of pipes in wet method phosphoric acid manufacture process stopped up, the most frequently used solution allowed the workman that the pipeline junction is taken apart exactly, adopts the external force collision pipeline to clear up.Such a labor cleaning's mode not only increased the workman labour intensity, extended clearance time, and also have some intrinsic shortcomings, as quick detachable in poor operability, pipeline and have a potential safety hazard, external force does not make the shock injury of pipeline and shortens its work-ing life etc.
The inventor is according to the practical experience of being engaged in for a long time phosphoric acid production with to phosphoric acid line of pipes dirt matter sampling analysis, analysis-by-synthesis the reason of phosphoric acid line of pipes fouling and the composition of dirty matter, thereby work out a kind of device of effectively cleaner phosphoric acid line of pipes dirt matter.
Summary of the invention
The object of the present invention is to provide a kind of washing unit of phosphoric acid line of pipes, to improve the transport capacity of phosphoric acid line of pipes, shorten scavenging period, reduce labour intensity and potential safety hazard.
A kind of washing unit of phosphoric acid line of pipes is characterized in that: comprise washings configured slot (1), supply acid tube (2), supply standby (3), washings Receiving bin (4), solution feed pump (5), time liquid pump (6), neutralizing treatment accumulator tank (7), acid elution liquid accumulator tank (8), recycle of alkali liquor valve (9) and the acid solution recovery valve (10) of managing of acid tube; Washings Preparation tank (1) is by being connected with washings Receiving bin (4) for acid tube (2), its pipeline is provided with solution feed pump (5), washings Receiving bin (4) is by being connected with washings Preparation tank (1) for the standby pipe of acid tube (3), its pipeline is provided with back liquid pump (6), washings Preparation tank (1) is connected 7 by pump with the neutralizing treatment accumulator tank) and acid elution liquid accumulator tank (8) connection, be separately installed with recycle of alkali liquor valve (9) and acid solution on its connecting tube and reclaim valve (10).
Beneficial effect of the present invention: simple to operate, safe and reliable, can effectively improve the cleaning efficiency of phosphoric acid line of pipes, alleviate labor strength, reduce potential safety hazard.
Description of drawings
Fig. 1 is circulating system structure schematic diagram of the present invention.
In figure, 1-washings configured slot, 2-are for acid tube, and 3-manages for acid tube is standby, 4-washings Receiving bin, and the 5-solution feed pump, 6-returns liquid pump, 7-neutralizing treatment liquid accumulator tank, 8-acid elution liquid accumulator tank 9-recycle of alkali liquor groove valve, 10-acid solution accumulator tank valve.
Embodiment
Further describe technical scheme of the present invention below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
As shown in Figure 1, with need clean for acid tube 2, reach back liquid pump 6 and couple together with washings configured slot 1, washings Receiving bin 4, solution feed pump 5 for the standby pipe 3 of acid tube, formation circulation cleaning system.
When carrying out neutralizing treatment, start solution feed pump 6 after the interior preparation neutralizing treatment of washings configured slot 1 liquid neutralizing treatment liquid is delivered to washings Receiving bin 4, when but washings Receiving bin 4 reaches the liquid level of ejector priming, start back liquid pump 6, washings is returned washings configured slot 1, make washings at washings configured slot 1, for acid tube 2, washings Receiving bin 4, the circulation between standby pipe 3, washings configured slot 1 for acid tube.After neutralizing treatment finishes, open recycle of alkali liquor groove valve 9, neutralizing treatment liquid is sent into used when neutralizing treatment liquid accumulator tank 7 washed in order to next time, close afterwards recycle of alkali liquor groove valve 9.
When carrying out acid elution, in washings configured slot 1, prepare acid elution liquid, make acid elution liquid at washings configured slot 1, for acid tube 2, washings Receiving bin 4, the circulation between standby pipe 3, washings configured slot 1 for acid tube.Washing is opened acid solution accumulator tank valve 10 after finishing, and acid elution liquid is sent into used when acidic cleaning liquid accumulator tank 8 washed in order to next time, closes afterwards acid solution accumulator tank valve 10.
In configuration acid elution liquid or neutralizing treatment liquid, can open recycle of alkali liquor groove valve 9 or acid solution accumulator tank valve 10, the washings in neutralizing treatment liquid accumulator tank 7 or acidic cleaning liquid accumulator tank 8 is sent in washings configured slot 1, close afterwards corresponding valve.
