The deamination device has the characteristics of capability of separating liquid ammonia without power consumption, simple structure, convenience for operation, remarkable separation effect, and the like.
Description
technical field:
The utility model relates to synthetic ammonia emptying gas Ammonia separation device, is directly involved in a kind of throttling expansion from freezing labyrinth type deamination device.
background technology:
Synthesis ammonia plant removes and contains N in ammonia synthesis circulation gas
2, H
2, NH
3also contain CH outward
4, the rare gas element such as Ar, work as CH
4when accumulation volume surpasses 20%, have a strong impact on the synthetic of ammonia, need the regular discharge synthetic cyclic gas, reduce CH
4content, contain NH in synthetic ammonia circulation gas
3: 20%, H
2: 36%, CH
4: 20%, N
2: 20:%, Ar:4%.Most factories have set up the cycle bleeder gas recovering device, and some employing washing flash methods reclaim ammonia, and steam consumption is large, and economic benefit is low; Some employing isobaric ammonia recovering devices, the plant area area is large, inferior separating effect; Research and develop a kind of power consumption low, floor space is little, and the cycle bleeder gas ammonia separating and reclaiming device of good separating effect is very necessary.
summary of the invention
The purpose of this utility model just is to provide a kind of new synthetic ammonia cycle bleeder moral stream and expands from freezing labyrinth type deamination device, can be in the situation that non-power consumption, throttling from refrigeration and effectively the Ammonia recovery utilization in separation removal cycle bleeder gas produce urea.
The purpose of this utility model is achieved in that throttling expansion is from freezing labyrinth type deamination device, there is tank body, lower cover, upper cover, throttling valve, traverse baffle, flow-stopping plate, gas outlet tube, the liquefied ammonia outlet pipe, tank body is the cylinder rolled into stainless steel plate, lower end welding lower cover, upper end welding upper cover, lower cover center drilling welding liquefied ammonia outlet pipe, upper cover center drilling welding gas outlet pipe, the combi inlet port pipe that throttling valve is arranged at tank body Lower Half left side opening eyelet welding tape splicing, at five layers of traverse baffle of inner tank wall welding, upper cover interior welds flow-stopping plate.
Because this device has adopted the combi inlet port pipe that throttling valve is arranged at tank body Lower Half left side opening eyelet welding tape splicing, at five layers of traverse baffle of inner tank wall welding, the structure of upper cover interior welds flow-stopping plate, synthetic ammonia cycle bleeder gas is after the throttling valve throttling, pressure is down to 9MPa by 22MPa, enter tank interior, volumetric expansion pressure further is down to 8MPa, temperature is down to-100 ℃ by 20 ℃, the cold that throttling discharges is condensed into liquefied ammonia by the gas ammonia in gas mixture, part liquefied ammonia gathers discharge at the lower cover place, part liquefied ammonia is carried secretly in uphill process through the labyrinth type traverse baffle by gas mixture, be attached on traverse baffle, under action of gravity, drop, in the lower cover inner accumulated, through the liquefied ammonia outlet pipe, discharge, due to the flow-stopping plate effect, residual gas overflows through gas outlet tube from the flow-stopping plate edge, the non-power consumption that has reached synthetic ammonia cycle bleeder gas ammonia gas and other gases separates efficiently.
the accompanying drawing explanation:
Accompanying drawing 1 shows the structural representation of a kind of throttling expansion of the utility model from the labyrinth type deamination device that freezes, and below in conjunction with accompanying drawing, is described further.
embodiment:
Accompanying drawing shows the structure of the novel a kind of throttling expansion of this experiment from the labyrinth type deamination device that freezes: have tank body 1, lower cover 2, upper cover 3, throttling valve 4, traverse baffle 5, flow-stopping plate 6, gas outlet tube 7, liquefied ammonia outlet pipe 8, described tank body 1 is the cylinder that the stainless steel plate with thickness 14 mm rolls into, 1.2 meters of diameters, high 3.0 meters, at the lower end of tank body 1 welding lower cover 2, weld 5 layers of traverse baffle 5 from 0.3 meter of tank body 1 lower end inwall, layer distance is 0.5 meter, the circular slab that the diameter that the stainless steel plate that traverse baffle 5 is is 4mm with thickness cuts into is 1 meter, all bore Φ 10mm circular hole, cut 1/4 disc after making, lacking face relatively misplaces and is welded on tank body 1 inside, form labyrinth.The gas inlet tube of the tank body 1 outer wall upper shed welding φ 108 * 3.5mm at 0.2 meter below distance lowest layer traverse baffle, inlet pipe connects throttling valve 4, tank body 1 upper end welding upper cover 2, at upper cover 2 center drilling welding gas outlet pipes 7, stainless steel tube for φ 108 * 3.5mm, at lower cover 2 center drilling welding liquefied ammonia outlet pipes 8, it is the stainless steel tube of φ 133 * 3.5mm.
principle of work
Synthetic ammonia cycle bleeder gas enters tank interior through throttling valve, after throttling expansion, pressure is down to 9MPa by 22MPa, enter tank interior, volumetric expansion pressure further is down to 8MPa, temperature is down to-100 ℃ by 20 ℃, by the ammonia condensation in gas mixture, be liquefied ammonia, gas mixture is carried secretly in the liquefied ammonia uphill process and is run into traverse baffle, be attached on traverse baffle, under action of gravity, drop, in the lower cover inner accumulated, discharge and collect through the liquefied ammonia outlet pipe, due to the flow-stopping plate effect, residual gas overflows through gas outlet tube from flow-stopping plate edge, having reached synthetic ammonia emptying gas ammonia and the effective of other gases separates, reduced greatly the situation of carrying secretly of drop.
Characteristics of the present utility model, because this device has adopted the combi inlet port pipe that throttling valve is arranged at tank body Lower Half left side opening eyelet welding tape splicing, at five layers of traverse baffle of inner tank wall welding, the structure of upper cover interior welds flow-stopping plate, effective condensation liquefaction ammonia from synthetic ammonia cycle bleeder gas, without power consumption, simple in structure, easy to operate.
