Abstract
The utility model discloses an improved ammonium phosphate flashing chamber structure. The improved ammonium phosphate flashing chamber structure comprises a flashing chamber (1), a charging pipeline (2), a material slurry circulation pump (3), a material slurry heater (4) and a discharging pipeline (5), wherein a cross sheath (6) is arranged at a position, close to a bottom pipe port, inside the flashing chamber. Compared with the prior art, the improved ammonium phosphate flashing chamber structure has the advantages that the cross sheath is arranged at a position, close to a bottom pipe port, inside the flashing chamber, so that the cost is low, the structure is simple, and the processing is easy; through the action of the cross sheath, a smooth and steady charging rate for the material slurry circulation pump is realized, the phenomenon of material slurry turbulence is avoided, and then, the circumstances that material slurry cakes into blocks are reduced effectively; meanwhile, the material slurry which is caked into blocks can be prevented from entering the charging pipeline, so that the probability of material slurry heater blockage is reduced, the power-on rate is increased, then the production cost is reduced, and the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of phosphorus ammonium flashing chamber, and specifically a kind of phosphorus ammonium flashing chamber improves structure.
Background technology
Phosphorus ammonium flashing chamber be in the production of a kind of phosphorus ammonium for realizing the production unit of neutralization, concentration process, be one of major equipment of producing of phosphorus ammonium.Its effect be by the slurry circulation pump by the phosphor ammonium slurry of High Temperature High Pressure by the well heater conveying that circulates, the moisture in phosphor ammonium slurry is vaporized rapidly, reach vapor-liquid separation, thereby improve 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 phosphate ore pulp, phosphoric acid, the neutralization of phosphor ammonium slurry, concentrated and dry, the packing of product ammonium phosphate etc. usually.In this series of process process, it is the most critical link of production process that the neutralization reaction of phosphor ammonium slurry reaches concentrated, it has been mainly the chemical reaction of 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, on the surface of the meeting inner tube wall that is bonded in flashing chamber in layer, form block, 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 to expend higher production cost, greatly affected the driving rate of device, then can badly influence the production efficiency of phosphorus ammonium simultaneously.
The utility model content
The problem existed for above-mentioned prior art, the utility model provides a kind of phosphorus ammonium flashing chamber to improve structure, can simplify when improving structure saving cost, 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, in the inner position near the bottom mouth of pipe of flashing chamber, is provided with the cross sheath.
The cross sheath is that the welding of stainless steel lath forms.
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, in the inner position near the bottom mouth of pipe of flashing chamber, the cross sheath is set, 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, can stop that the slip that has been bonded to piece enters feed pipe simultaneously, reduced the obstruction probability of slip well heater, improve driving rate, then reduced production cost, improved production efficiency.
The accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model.
In 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
Below in conjunction with accompanying drawing, the utility model is described further.
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, in the inner position near the bottom mouth of pipe of flashing chamber 1, is provided with cross sheath 6.
As preferably, cross sheath 6 forms for the welding of stainless steel lath, can avoid causing because of life-time service the corrosion of cross sheath 6, has extended the work-ing life of cross sheath 6, has reduced and has safeguarded the cycle of changing, and further provides cost savings.
Further, in the inner position near the bottom mouth of pipe of flashing chamber 1, be welded with a circle cross sheath 6, can guarantee stability and persistence that cross sheath 6 uses, make the purpose of this utility model 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 feeds back to flashing chamber 1 from slip output channel 5, circulation and so forth after slip is sent into to 4 heating of slip well heater again.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, form steam after moisture boiling in slip, 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 the inner position near the bottom mouth of pipe of flashing chamber 1 in Fig. 1, thereby reach the turbulent flow phenomenon produced while avoiding phosphor ammonium slurry to enter pipeline 2, the slip flow can held stationary speed, and then effectively reduced the situation that slip is bonded to piece, simultaneously cross sheath 6 can stop that the slip that has been bonded to piece on the inwall of 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.
