Technical field:
The utility model relates to the hypergravity oxygen-rich oxide reclaim equiment of Wet-type oxidation sweetening technique, is applicable to the catalyst regeneration process of various wet oxidation process.
Background technology:
Wet oxidation desulfurization is that the hydrogen sulfide absorbed by solution is oxidized to elementary sulfur and the technique separated in the liquid phase.It has, and to remove precision high, and operating flexibility is large, the features such as operating cost is low, the difference of catalyst is used according to sweetening process, Wet-type oxidation sweetening technique is divided into arsyl technique, vanadium base technique, iron-based technique three kinds, arsyl technique due to desulfuration efficiency low, less use; The representative method of vanadium base technique is ADA method, tannin process, vanadium base technique exists that Sulfur capacity is low, vanadium to shortcomings such as environments, be subject to environmental protection restriction.The representative technique of iron-based technique and Complexing Iron sulfur removal technology is as the LO-CAT technique of mrichem company, the Sulferox method etc. of Shell and Dow company exploitation, has the advantages such as nontoxic, efficient, high activity and high selectivity and is widely used due to Complexing Iron sulfur removal technology.This technique can be divided into the absorption of hydrogen sulfide and catalyst oxidation to regenerate two processes, and the solubility of hydrogen sulfide in alkali lye is comparatively large, absorbs and is easy to carry out, the selection of reactor is also more various, as LO-CAT technique absorption reactor thermally has bubble tower, packed tower, venturi, the various ways such as static mixer.And in oxidizing process, because the solubility of oxygen in Complexing Iron solution is low, the bubble tower that the liquid holdup that oxidation reactor adopts always is large, gas residence time is long, bubble tower has structure simple, stable feature, but bulky, and mass-transfer efficiency is low, constrain Complexing Iron technique miniaturized, the development of sledge dressization.
Hypergravity is Novel process strengthening device, has been applied to Complexing Iron sulfur removal technology, and Chinese patent 200710101508.0 reports a kind of method of hypergravity Complexing Iron desulfurization hydrogen sulfide, the absorber of the method adopts hypergravity, oxidator adopts bubble tower, and oxidation furnaces is huge, and efficiency is low.Chinese patent 201110076120.6 and China 201310353789.4 also report similar approach, but oxidizing process uses air to carry out at ambient pressure, and because dividing of oxygen is forced down, concentration of oxygen gas is low, causes the oxidative rate of ferrous ion low, limits the disposal ability of technique.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of oxidation furnaces size that reduces, shorten the oxidation regeneration time, oxidation efficiency is high, improve the treating capacity of wet oxidation-desulfurizing technique, oxygen utilization is high, the hypergravity oxygen-rich oxide reclaim equiment of the Wet-type oxidation sweetening technique that energy consumption is very low.
The purpose of this utility model can be reached by following measure: the hypergravity oxygen-rich oxide reclaim equiment of Wet-type oxidation sweetening technique, it is characterized in that it comprises oxygenerator, oxygenerator connects hypergravity machine, the gas outlet of hypergravity machine connects knockout drum, the liquid outlet of hypergravity machine connects vacuum tank, knockout drum and vacuum tank UNICOM.
The utility model can produce following good effect compared with the prior art: the utility model provides the equipment of efficient oxidation regenerative sulfur binding rich solution under a kind of super gravity field, it is in conjunction with the feature of wet oxidation-desulfurizing and hypergravity machine, oxygen-enriched air is adopted to replace air oxidation regenerated catalyst, drastically increase oxygen solubility in the catalyst, the effect making hypergravity strengthen mass transfer is really played, and oxygenation efficiency increases substantially.Not only reduce the size of oxidation furnaces, shorten the time of oxidation regeneration simultaneously, improve the treating capacity of wet oxidation-desulfurizing technique.Specifically, the utility model has the following advantages:
1, oxidation efficiency is high, and the oxygenation efficiency of single iron protoxide ion is more than 60%;
2, treating capacity is large, and the strengthening effect of mass transmitting of hypergravity and the raising of catalyst oxidation regeneration rate, increase the disposal ability of wet oxidation-desulfurizing technique;
3, consume low, according to air bubbling oxidation, because oxygen utilization rate is low, air need excessive a lot of requirement that could meet oxidation regeneration catalyst, cause the energy consumption of air blast large.And oxygen-enriched air can be recycled, substantially increase oxygen utilization rate, energy consumption is very low.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Embodiment: the hypergravity oxygen-rich oxide reclaim equiment (see Fig. 1) of Wet-type oxidation sweetening technique, it comprises oxygenerator 1, oxygenerator 1 connects hypergravity machine 2, the gas outlet of hypergravity machine 2 connects knockout drum 3, the liquid outlet of hypergravity machine 2 connects vacuum tank 4, knockout drum 3 and vacuum tank 4 UNICOM.
When carrying out oxidation regeneration, sulfur removing pregnant solution and enter hypergravity machine 2 respectively from the oxygen-enriched air of oxygenerator 1, oxidation reaction is there is in filler, by catalyst regeneration, hypergravity machine 2 gas out enters knockout drum 3, through catching after mist dewaters, directly emptying according to oxygen concentration, or be circulated to oxygen generation system leading portion, collecting oxygen again.Catalyst solution after oxidation regeneration enters vacuum tank 4, UNICOM between vacuum tank 4 and knockout drum 3, with the pressure of stable hypergravity machine 2.The solution of vacuum tank 4 is extruded by pressure, continues to react with hydrogen sulfide as the solution after regeneration.
By changing oxygen concentration in air, and then rich solution oxidation regeneration technique is evaluated.Related data sees the following form.
The Complexing Iron catalyst that the catalyst used in embodiment provides for Yantai Xin Rui Environmental Protection Technology Co., Ltd.Hypergravity machine rotating speed 1500rmp;
As can be seen from the contrast of embodiment 1 and 2,3,4,5, after raising oxygen concentration, the oxygenation efficiency of ferrous ion significantly improves.
