Abstract
An ammonia distilling tower comprises a barrel, the barrel is provided with a tray along the axial direction, the top of the barrel is provided with an ammonia vapor dephlegmator; the top of the ammonia vapor dephlegmator is provided with an exhaust valve; the lateral part of the barrel is provided with an ammonia steaming inlet, and the bottom of the barrel is provided with an ammonia steaming wastewater outlet; and the external surface of the barrel is provided with thermal-insulation support rings at intervals along the axial direction. According to the technical scheme, by arranging the thermal-insulation support rings at the external surface of the barrel, the heat loss in the barrel is reduced, and because the heat in the barrel comes from steam, the use amount of steam is reduced, the processing volume of the discharged wastewater is reduced and the production cost is reduced.
Description
Technical field
The technical program relates to a kind of coking chemical waste water ammonia still process equipment, relates in particular to the ammonia still in ammonia still process equipment.
Background technology
In coking industry production process, can produce a large amount of ammonia-containing waters, therefore waste water does not allow outer row because containing ammonia, and ammonia-containing water is serious to metallic corrosion, so must discharge after ammonia extraction.Open steam ammonia still process is the technique of deamination more widely of China's coking industry application, is that waste water is delivered in ammonia still, with a large amount of steam, distills, and ammonia is extracted.What the material overwhelming majority of existing ammonia still adopted is stainless steel, well-known stainless steel rapid heat dissipation, vapor condensation speed in tower is accelerated, vapor condensation will with the steam waste water outer row that lumps together, the quickening of vapor condensation speed has increased the treatment capacity of efflux wastewater virtually; Ammonia still be take external open steam as thermal source, after vapor condensation in order to guarantee that ammonia in tower can be distilled out of the steam that must supplement in tower to guarantee the required heat of ammonia still process.
Summary of the invention
The technical program is to provide a kind of can reduce steam consumption, raising ammonia still process efficiency, the treatment capacity that reduces efflux wastewater, the ammonia still reducing production costs, and concrete technical scheme is as follows:
A kind of ammonia still, comprise cylindrical shell, in cylindrical shell, along axis direction, be provided with tower tray, the top of cylindrical shell is provided with ammonia vapour dephlegmator, the top of ammonia vapour dephlegmator is provided with vent valve, the sidepiece of cylindrical shell is provided with ammonia still process water inlet, and the bottom of cylindrical shell is provided with distilled ammonia wastewater outlet, and the outside surface of described cylindrical shell is interval with insulation supporting cup along axis direction.
The top at ammonia still process water inlet place is provided with erosion control cover plate in described cylindrical shell, spray sputter when having reduced ammonia still process water and entering cylindrical shell.
In described cylindrical shell, the top in distilled ammonia wastewater exit is provided with anti-flowing plate.
The bottom that distilled ammonia wastewater outlet is located to cylindrical shell, can discharge the distilled ammonia wastewater in cylindrical shell fast.
Because the bottom of cylindrical shell is that the volume of arc and ammonia still is larger, be not easy to place, the bottom of cylindrical shell is connected with pedestal, be convenient to the placement of ammonia still.
The technical program is provided with insulation supporting cup outward by the cylindrical shell at ammonia still, has reduced the calorific loss in cylindrical shell, because the heat in cylindrical shell comes from steam, has therefore reduced the consumption of steam, has reduced the treatment capacity of efflux wastewater; Reduced production cost.
Accompanying drawing explanation
Fig. 1 is that the technical program be take the structural representation of the first half that A-A is gap;
Fig. 2 is that the technical program be take the structural representation of the Lower Half that A-A is gap.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the technical program.
Referring to Fig. 1 and Fig. 2, this ammonia still, comprises cylindrical shell 1, and the bottom of cylindrical shell 1 is connected with pedestal 5; The outside surface of cylindrical shell 1 is interval with insulation supporting cup 4 along axis direction, and insulation supporting cup 4 can directly be welded on the outside surface of cylindrical shell 1, and the spacing of adjacent two insulation supporting cups is 3m left and right.Cylindrical shell 1 is interior is interval with tower tray 3 along axis direction, the top of cylindrical shell 1 is provided with ammonia vapour dephlegmator 2, the top of ammonia vapour dephlegmator 2 is provided with vent valve 12, this vent valve 12 is for discharging the ammonia steaming, the sidepiece of cylindrical shell 1 is provided with ammonia still process water inlet 10, steam-in 9 and alkali liquor inlet 8, ammonia still process water inlet 10 be positioned at steam-in 9 and alkali liquor inlet 8 above, the top at the interior ammonia still process water inlet of cylindrical shell 1 place 10 is provided with erosion control cover plate 11, and erosion control cover plate 11 is welded on the inwall of cylindrical shell 1; The bottom of cylindrical shell 1 is provided with distilled ammonia wastewater outlet 6, and the top of the interior distilled ammonia wastewater outlet 6 of cylindrical shell 1 is provided with anti-flowing plate 7, and anti-flowing plate 7 also can directly be welded on the inwall of cylindrical shell 1.
During work, ammonia still process water enters from the ammonia still process water inlet 10 of cylindrical shell 1 sidepiece, and calcium hydroxide or sodium hydroxide are joined in ammonia still process water by alkali liquor inlet 8, carries out alkali and analyse deamination under mistake alkali condition, makes the ammonium salt in ammonia still process water be converted into free ammonia and salt; Then in steam-in 9, pass into steam, steam is by up ascension of bottom, thereby in adverse current is mixed, ammonia still process water is carried out to heat temperature raising, when ammonia still process water temp rises to certain numerical value (95 ℃ of left and right), ammonia in water is steamed comparatively thoroughly, vent valve 12 from top after ammonia vapour dephlegmator 2 is discharged, and the distilled ammonia wastewater of bottom enters subsequent processes system cools and processes from distilled ammonia wastewater outlet 6 is discharged.
