Abstract
The utility model relates to a crystallization centrifugal system of a thiamine working section, which comprises a plurality of crystallization pumps. The crystallization pumps are communicated with a plurality of crystallization tanks through conveying pipes, the crystallization tanks are connected with a plurality of centrifugal machines through pipelines, the centrifugal machines are connected with a dryer through blanking pipes, the dryer is connected with a bunker through a discharging pipeline, two crystallization pumps are adopted and are arranged on the conveying pipes in parallel, the discharging pipes of the crystallization pumps are respectively provided with a valve, two crystallization tanks are adopted and are arranged on the conveying pipes in parallel, the first crystallization tank is connected with the first centrifugal machine through a lower pipeline, the second crystallization tank is connected with the second centrifugal machine through a pipeline, and the first centrifugal machine and the second centrifugal machine are connected with the blanking pipe. Since two devices and more large devices are used in parallel and can be matched flexibly and conveniently, the trouble in replacement of other devices as a result of repair of one device can be reduced, the labor intensity can be lowered greatly, the operation in the production of the thiamine working section can be more stable, the recovery of ammonia in gas can be improved, and the corrosion on devices on the follow-up working section can be reduced.
Description
Technical field
The utility model relates to the result and the centrifugation systems of ammonium sulfate workshop section.
Background technology
In ammonium sulfate workshop section, through the raw gas entering saturex of preheating, the ammonia in the coal gas is by the sulfuric acid absorption in the mother liquor; Generate ammonium sulfate crystallization; The sulphur crystalline ammonium is along the pipe core in the saturex, and the crystallisation chamber that gets into hypomere through the crystallization pump is discharged at this isolating sulphur crystalline ammonium and a small amount of mother liquor and carries out spinning in the whizzer; The filtering mother liquor, the sulphur crystalline ammonium is imported feed bin after getting into the moisture eliminator drying.In the sulphur workshop section, a set of equipment comprises a crystallization pump, a crystallizer tank, a whizzer, a moisture eliminator and feed bin that connects successively at present.Each complete equipment is independent production, wherein has a kind of device to go wrong in a set of equipment, and all devices of this complete equipment all need all stop so, and change another set of equipment into, and labour intensity is big.The crystallization centrifugation systems of this mode, device switching is frequent, makes in the coal gas ammonia not divisible, and gas line is caused corrosion, makes the washing oil emulsification of crude benzol workshop section, influences the crude benzol recovering effect.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of sulphur ammonium work preheater is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of ammonium sulfate workshop section crystallization centrifugation systems comprises the crystallization pump, and crystallization pump and crystallizer tank are through carrier pipe UNICOM; Crystallizer tank is connected with whizzer through pipeline, and whizzer is connected with moisture eliminator through tremie pipe, and moisture eliminator is connected with feed bin through drainage line; Said crystallization pump is two crystallization pumps, is connected in parallel on the feeding pipe; On the extraction line of each crystallization pump, be provided with valve, said crystallizer tank is that two crystallizer tanks are connected in parallel on the carrier pipe, and pipeline was connected with first whizzer under first crystallizer tank passed through; Second crystallizer tank is connected with second whizzer through pipeline, and first whizzer all is connected with tremie pipe with second whizzer.
Adopt technique scheme; The utility model has following advantage: because two complete equipments or the parallel connection of more much equipment are used; Make between each equipment cooperate flexible; Reduced because of overhauling certain equipment and must switch the trouble of all the other equipment, greatly reduced labour intensity, and make the ammonium sulfate workshop section production operation more stable.Improve the recovery of ammonia in the coal gas, reduced corrosion on Equipment follow-up workshop section.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
A kind of ammonium sulfate workshop section crystallization centrifugation systems as shown in Figure 1 comprises the crystallization pump, and crystallization pump and crystallizer tank are through carrier pipe 5 UNICOMs; Crystallizer tank is connected with whizzer through pipeline, and whizzer is connected with moisture eliminator 11 through tremie pipe 10, and moisture eliminator 11 is connected with feed bin 12 through drainage line; Said crystallization pump is that two crystallization pumps 2,3 are connected in parallel on the feeding pipe 5; On the extraction line of each crystallization pump, be provided with valve, the first crystallization pump 2 is connected with saturex through first feed-pipe 1, and the second crystallization pump 3 is connected with another saturex through second feed-pipe 4; Said crystallizer tank is that two crystallizer tanks 6,7 are connected in parallel on the carrier pipe 5; Pipeline was connected with first whizzer 8 under first crystallizer tank 6 passed through, and second crystallizer tank 7 is connected with second whizzer 9 through pipeline, and first whizzer 8 all is connected with tremie pipe 10 with second whizzer 9.
The utility model is to adopt the parallel connection of two complete equipments, and the utility model can also adopt three complete equipments or quadruplet equipment to carry out parallel connection according to the size in workshop, and its handiness is bigger.
