Abstract
The utility model discloses a citric-acid washing working-procedure washing-water utilizing device, wherein a solid-liquid mixture of citric acid and calcium sulphate enters a material-liquid filtering area, a citric-acid solution is filtered and stored into a citric-acid filtering-liquid storing tank, the calcium sulphate carrying the partial citric acid enters a concentrated-acid washing area along with the rotation of a band filter, a greater part of citric acid is washed out by washing water in the area, the else calcium sulphate in the area is continuously washed by using dilute acid until the content of the citric acid in the dilute acid reaches a certain concentration, and then the washing water is replaced. The calcium sulphate which still contains the partial citric acid after being washed in the concentrated-acid washing area sequentially enters a dilute-acid washing area to be continuously washed, the residual citric acid is entirely washed out in the area, the else calcium sulphate in the area is continuously washed by the washing water and enters the concentrated-acid washing area to be washed after the citric acid of the part of washing water reaches a certain concentration and becomes the dilute acid, and the fresh washing water is replaced in the dilute-acid washing area.
Description
Technical field
The utility model belongs to calcium salt method to be produced and to wash the energy-saving and cost-reducing technical field of sour operation in the citric acid process, relates generally to wash sour operation and wash water reuse.
Background technology
Calcium salt method is produced in the citric acid technical process, citric acid is after neutralization, decomposing, enter and wash sour operation, purpose is that the calcium sulfate that will produce in citric acid and the decomposable process separates, behind primary filter, most citric acid solution is filtered separation, but also residual a large amount of citric acid in the calcium sulphate solid slag, therefore, this part citric acid must be reclaimed the yield that can improve Citric Acid Production.The general method of flushing water wash rinse that adopts develops this part citric acid, but in washing process, if water consumption is too many, not only increased the water consumption of Citric Acid Production, if this part dilture acid mixes with concentrated acid, enter the back operation together, then can cause the reduction of citric acid solution overall density, and then increase the steam consumption of follow-up enrichment process.
Summary of the invention
The technical problems to be solved in the utility model is to recycle Citric Acid Production to wash the wash water of sour operation, makes it reach sufficient utilization, reduces the water consumption of this operation and the steam consumption of back operation, and then reduces the production cost of citric acid, realizes energy-saving and cost-reducing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the solidliquid mixture of citric acid and calcium sulfate is put into the feed liquid filtering area, most citric acid is filtered, be stored to citric acid filtered fluid storage tank, rotation along with band filter, the calcium sulfate that carries part citric acid enters the concentrated acid scrubbing section, in this zone, the citric acid that major part is carried secretly is washed out by wash water, this part dilture acid is recycled to the concentrated acid storage tank through pipeline, continue to use dilture acid that other calcium sulfate that enters the concentrated acid scrubbing section is washed, citric acid content reaches finite concentration in dilture acid, changes wash water again.So promptly save slurry, ensured the dilture acid concentration of citric acid again, be follow-up concentrated a large amount of steam of having saved; The calcium sulfate that after the washing of concentrated acid scrubbing section, still contains part citric acid, then enter the dilture acid scrubbing section and continue washing, in this zone, remaining citric acid is all washed out, washings enter the dilture acid scrubbing section through dilture acid storage tank, dilture acid reuse pipeline and continue other calcium sulfate of washing, after the citric acid of this part wash water reaches finite concentration, just enter feed liquid concentrated acid scrubbing section and wash, the dilture acid scrubbing section is then changed fresh wash water again.
The beneficial effects of the utility model are: made full use of water resource, reduced the water consumption of this operation, guaranteed the yield of citric acid, reduced production cost, improved economic benefit.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a device schematic diagram of the present utility model;
Among the figure: 1, band filter, 2, feed liquid filtering area, 3, concentrated acid scrubbing section, 4, the dilture acid scrubbing section, 5, dilture acid reuse pipeline, 6, concentrated acid reuse pipeline, 7, concentrated acid reuse pipeline control valve, 8,9, dilture acid reuse pipeline control valve, 10, the concentrated acid storage tank, 11, dilture acid storage tank, 12, citric acid filtered fluid storage tank.
The specific embodiment
With reference to accompanying drawing, the solidliquid mixture of citric acid and calcium sulfate enters feed liquid filtering area (2), most citric acid is filtered and is stored to citric acid filtered fluid storage tank (12), rotation along with band filter, the calcium sulfate that carries part citric acid enters concentrated acid scrubbing section (3), in this zone, most of citric acid of being carried secretly is washed out by wash water, enter concentrated acid storage tank (10), this part dilture acid is delivered to concentrated acid scrubbing section (3) through concentrated acid reuse pipeline (6) to be continued other calcium sulfate is washed, citric acid content reaches finite concentration in concentrated acid, changes wash water again.The calcium sulfate that after concentrated acid scrubbing section (3) washing, still contains part citric acid, then enter dilture acid scrubbing section (4) and continue washing, in this zone, remaining citric acid is all washed out, washings are through dilture acid storage tank (11), dilture acid reuse pipeline (5) enters dilture acid scrubbing section (4) and continues other calcium sulfate of washing, after the citric acid in this part wash water reaches finite concentration, just entering concentrated acid scrubbing section (3) washs, dilture acid scrubbing section (4) is then changed fresh wash water again, so promptly made full use of water resource, reduce the water consumption of this operation, guaranteed the yield of citric acid again.Thereby reduced production cost, improved economic benefit.
Claims (1)
1. lemon pickling acid operation wash water use device, comprise band filter (1), feed liquid filtering area (2), concentrated acid scrubbing section (3), dilture acid scrubbing section (4), dilture acid reuse pipeline (5), concentrated acid reuse pipeline (6), concentrated acid reuse pipeline control valve (7), dilture acid reuse pipeline control valve (8), dilture acid reuse pipeline control valve (9), concentrated acid storage tank (10), dilture acid storage tank (11) and citric acid filtered fluid storage tank (12), it is characterized in that the workbench of band filter is divided into feed liquid filtering area (2), concentrated acid scrubbing section (3), (4) three zones of dilture acid scrubbing section, the dilture acid that dilture acid storage tank (11) is collected can return concentrated acid scrubbing section (3) and with dilture acid scrubbing section (4) feed liquid be washed, and realizes the recycling of wash water.
