Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
A kind of efficiency of waste gas hydrogen sulphide disposal unit, as it is shown in figure 1, include tourie 1, regenerating tank 2, sulfur foam storage tank 3 and the solid-liquid separator 4 being sequentially connected with；The sulfur removing pregnant solution that described tourie 1 flows out respectively enters described regenerating tank 2 by the road and returns tourie 1 as circulation fluid；The ejector 10 for from top to bottom being sprayed by waste gas it is provided with in described tourie 1；Described solid-liquid separator 4 is provided with solid phase floss hole and the liquid-phase outlet being connected by pipeline with described sulfur foam storage tank；Described sulfur foam storage tank 3 is provided with the lean solution circulating pump 7 in order to lean solution to be injected into described tourie 1；Described regenerating tank 2 is provided with air outlet and the air pump 6 for air-breathing in regenerating tank；It is provided with sulfur foam pump 8 between described sulfur foam storage tank 3 and described solid-liquid separator 4.
Feature for exhaust gas pressure low (normal pressure or negative pressure), ejector is used to introduce exhaust gas in tourie, react with efficient composite desulfurizer in tourie, hydrogen sulfide in waste gas is all absorbed, the desulfurizing agent absorbing hydrogen sulfide enters regenerating tank and the air oxidation generation drusen blasted, desulfurizing agent after filtering enters back into tourie, completes the recycling of desulfurizing agent.Concrete course of reaction is as follows:
Absorb and react:
R-X (composite desulfurizing agent)+H2S→R-HS+HX
Regenerative response:
Composite desulfurizing agent system is reacted with hydrogen sulfide in tourie, forms firm sulfide, forms sulfur removing pregnant solution, and rich solution is sufficiently mixed with air in regenerating tank, rapid regeneration under the effect of composite catalyst, generates sulfur.Lean solution recycles.The Sulfur capacity of desulfurizing agent is high.The Sulfur capacity of this desulfurizing agent is up to 0.3%～0.5%；And the Sulfur capacity of the most on-the-spot general desulfurizing agent is less than 0.1%.Absorbing reaction to complete in 10 seconds, absorb response speed fast, not absorbing carbon dioxide, the impact that desulfurizing agent absorption reaction is produced by carbon dioxide can be ignored.Meanwhile, reproduction speed is fast.The complex catalyst system of exploitation makes sulfur removing pregnant solution reproduction speed very fast, and general only can completing in several seconds is reacted.
It should be noted that because absorbing and being all mainly chemical reaction with regenerative process, so absorption efficiency is high, reproduction speed is also fast, and will not be stripped off sulfide in regenerative process.Whole system is only because taking away a part of liquid in drusen separation process, so only existing the loss of fraction band liquid.In regenerative process, the drusen of generation is very big, and solid-liquid is easily isolated, and separating technology is fairly simple.In running outside sulphur removal sulphur, do not produce any refuse, thus dirty without secondary.
Being provided with liquidometer 5 and Pressure gauge 9 on described tourie, staff can observe the force value in tank and liquid level condition intuitively, such as emergency situations, can handle it in time.
It is pointed out that and be provided with check valve between described lean solution circulating pump 7 and described sulfur foam storage tank 3.It is designed with check valve between described tourie 1 and described regenerating tank 2 and between described regenerating tank 2 and described sulfur foam storage tank 3 and between described sulfur foam storage tank 3 and described solid-liquid separator 4, it is equipped with check valve on the described clean gas outlet of tourie 1 and the import of sulphur-containing exhaust gas, effectively prevents liquid from flowing backwards.
Wherein, described ejector 10 is arranged on the top of described tourie, its simultaneously with described sulphur-containing exhaust gas import and return the sulfur removing pregnant solution pipeline of tourie as circulation fluid and be connected.First in the case of normal pressure or negative pressure, injection apparatus is utilized to introduce exhaust gas into desulfuration absorbing tower, it is not necessary to pressurized equipment.
Waste gas initially enters the ejector of tourie 1 doctor solution with circulating pump through pipeline and is sufficiently mixed, and is ejected into bottom above tourie 1.In tourie 1, hydrogen sulfide gas is absorbed after being sufficiently mixed with doctor solution, purifies gas emptying, and doctor solution enters ejector 10 through a part of self-loopa liquid as absorption tower of circulating pump, and another part enters the air regenesis that regenerating tank is come with aerator.In regenerating tank, use air oxidation principle, utilize efficient composite catalyst, make desulfurizing agent rich solution at normal temperature and pressure oxidation regeneration.Sulfide in doctor solution is oxidized to sulfur, and desulfurizing agent rich solution is reproduced into lean solution.
Lean solution enters sulfur foam storage tank together with sulfur foam, and sulfur foam storage tank upper clear supernate is back to tourie 1, and bottom sulfur-bearing iodine solution enters solid-liquid separator 4 after sulfur foam pump pressurizes and separates the use of sulfur Posterior circle.Isolated sulfur stores.In running amount infused by sulfur number and regenerative process in the water yield taken away determine, need to run certain time is determined supplementing.
This device desulfuration efficiency height, non-secondary pollution, equipment volume is little, be quick on the draw, and normal temperature and pressure is renewable,.Under the conditions of ambient temperature 5～50 DEG C, absorb reaction the least with the efficiency change of regenerative response.The advantages such as convenient management, energy consumption are low, operating cost is low.It is crucial that in the case of normal pressure or negative pressure, can guarantee that waste gas carries out removing the process of hydrogen sulfide in entering device.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
