Abstract
The invention discloses an ammonium phosphate flash evaporation chamber improved structure which comprises a flash evaporation chamber (1), a feed pipeline (2), a slurry circulating pump (3), a slurry heater (4) and a discharge pipeline (5). The part, close to a pipe opening on the bottom, in the flash evaporation chamber is provided with a cross-shaped sheath (6). Therefore, compared with the prior art, the ammonium phosphate flash evaporation chamber improved structure is low in cost, simple, and easy to process; the slurry circulating pump maintains the stable feeding velocity through the effect of the cross-shaped sheath, the slurry turbulent flow phenomenon is prevented, and further, the possibility of bonding slurry into blocks is reduced; meanwhile, slurry, which is bonded into blocks, can be prevented from entering the feed pipeline, so that the blocking possibility of the slurry heater is reduced, the driving rate is improved, and further, the production cost is lowered while the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of phosphorus ammonium flashing chamber, specifically is that a kind of phosphorus ammonium flashing chamber improves structure.
Background technology
Phosphorus ammonium flashing chamber is the production unit that is used for realizing neutralization, concentration process during a kind of phosphorus ammonium is produced, and is one of major equipment of phosphorus ammonium production.Its effect is by the slurry circulation pump phosphor ammonium slurry of High Temperature High Pressure to be carried by the well heater circulation, and the moisture in the phosphor ammonium slurry is vaporized rapidly, reaches vapor-liquid separation, thereby improves the concentration of phosphor ammonium slurry.
The phosphorus ammonium is as the basic material of production composite fertilizer, and its technological process of production can be divided into extraction and the filtration of the producing of phosphorus ore slurry, phosphoric acid usually, the neutralization of phosphor ammonium slurry, concentrates and dry the packing of product ammonium phosphate etc.In this series of process process, the neutralization reaction of phosphor ammonium slurry reaches and concentrates is the most critical link of production process, it mainly is the chemical reaction of finishing phosphoric acid and ammonia, the process that generates the phosphorus ammonium and the phosphor ammonium slurry of lower concentration is purified, and make phosphor ammonium slurry enter the dry slurry moisture that reduces of drying tower by piston high-pressure pump.Yet, because phosphor ammonium slurry has certain cohesiveness, form block on the surface of the meeting inner tube wall that is bonded in flashing chamber in layer, can under the shock action of slip, come off, and then the occluding device discharging mouth of pipe or the tube bank of process recycle pump obstruction well heater, need frequent parking cleaning well heater and flashing chamber in therefore producing, need expend higher production cost, influence simultaneously the driving rate of device greatly, can badly influence the production efficiency of phosphorus ammonium then.
Summary of the invention
Problem at above-mentioned prior art existence, the invention provides a kind of phosphorus ammonium flashing chamber and improve structure, can save cost, simplify when improving structure, realize the speed of slurry circulation pump charging held stationary, avoid the generation of slip turbulent flow phenomenon, and then effectively reduce the situation that slip is bonded to piece, and reduce the obstruction probability of slip well heater, improve driving rate, then reduce production costs, enhance productivity.
To achieve these goals, this phosphorus ammonium flashing chamber improves structure and comprises flashing chamber, feed pipe, slurry circulation pump, slip well heater and discharge pipe, the below of flashing chamber is connected with feed pipe, the sidewall of flashing chamber is connected with discharge pipe, feed pipe is connected with discharge pipe with the slip well heater by interconnective slurry circulation pump successively, is provided with the cross sheath in the inner position near the bottom mouth of pipe of flashing chamber.
The cross sheath constitutes for the welding of stainless steel lath.
Be welded with a circle cross sheath in the inner position near the bottom mouth of pipe of flashing chamber.
Compared with prior art, this phosphorus ammonium flashing chamber improves structure and in the inner position near the bottom mouth of pipe of flashing chamber the cross sheath is set, and is with low cost, simple in structure, is easy to processing; Realized the speed of slurry circulation pump charging held stationary by the effect of cross sheath, avoided the generation of slip turbulent flow phenomenon, and then effectively reduced the situation that slip is bonded to piece, simultaneously can stop that the slip that has been bonded to piece enters feed pipe, reduced the obstruction probability of slip well heater, improve driving rate, reduced production cost then, improved production efficiency.
Description of drawings
Fig. 1 is agent structure synoptic diagram of the present invention.
Among the figure: 1, flashing chamber, 2, feed pipe, 3, the slurry circulation pump, 4, the slip well heater, 5, discharge pipe, 6, the cross sheath.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, this phosphorus ammonium flashing chamber improves structure and comprises flashing chamber 1, feed pipe 2, slurry circulation pump 3, slip well heater 4 and discharge pipe 5, the below of flashing chamber 1 is connected with feed pipe 2, the sidewall of flashing chamber 1 is connected with discharge pipe 5, feed pipe 2 is connected with discharge pipe 5 with slip well heater 4 by interconnective slurry circulation pump 3 successively, is provided with cross sheath 6 in flashing chamber 1 inner position near the bottom mouth of pipe.
As preferably, cross sheath 6 constitutes for the welding of stainless steel lath, can avoid causing because of life-time service the corrosion of cross sheath 6, has prolonged the work-ing life of cross sheath 6, has reduced and has safeguarded the cycle of changing, and further provides cost savings.
Further, be welded with a circle cross sheath 6 in flashing chamber 1 inner position near the bottom mouth of pipe, can guarantee stability and persistence that cross sheath 6 uses, make purpose of the present invention reach optimal result of use.
Working process of the present invention is: phosphor ammonium slurry enters slurry circulation pump 3 from the bottom mouth of pipe of flashing chamber 1 through feed pipe 2, and slurry circulation pump 3 is sent slip into slip well heater 4 heating backs and fed back to flashing chamber 1 again from slip output channel 5, circulation and so forth.After the phosphor ammonium slurry of High Temperature High Pressure enters flashing chamber 1 again by slip output channel 5, pressure will descend rapidly, boiling point lowering, moisture boiling back in the slip forms steam, discharge from the steam drain at flashing chamber 1 top, thereby reach reduction moisture, improve the pulp density effect.Be welded with a circle cross sheath 6 in flashing chamber 1 inner position near the bottom mouth of pipe among Fig. 1, thereby reach the turbulent flow phenomenon that produces when avoiding phosphor ammonium slurry to enter pipeline 2, the slip flow can held stationary speed, and then reduced the situation that slip is bonded to piece effectively, simultaneously cross sheath 6 can stop that the slip that has been bonded to piece on the inwall of the flashing chamber 1 piece that comes off enters feed pipe 2, reduced the obstruction probability of feed pipe 2 and slip well heater 4, improved driving rate, then reduce production cost, improved production efficiency.
