Description
Technical field
The utility model relates to a kind of hydrogen sulfide odor removal of synthesis gas tail gas.
Background technology
In synthesis gas tail gas, carbon dioxide accounts for more than 95%, and wherein hydrogen sulfide gas accounts for 5-2000ppm.If this part hydrogen sulfide gas directly discharge has greater environmental impacts.On general industry, hydrogen sulfide gas deodorizing adopts first water to absorb the way of alkali liquor absorption again.But containing great amount of carbon dioxide in synthesis gas, hydrogen sulfide gas is relatively less, if adopt alkali liquor absorption, because alkali lye also can absorbing carbon dioxide, alkali lye consumption can be caused excessive, with high costs.
Summary of the invention
Technical problem to be solved of the present utility model is that providing a kind of adopts photochemical catalytic oxidation deodorizing, and automaticity is high, the hydrogen sulfide odor removal of the synthesis gas tail gas of good deodorization effect.
In order to solve technical problem to be solved, the utility model have employed following technical scheme:
A hydrogen sulfide odor removal for synthesis gas tail gas, comprises exhaust collection tank, photochemical catalytic oxidation deodorizing device, frequency converter, PLC, ozone detector, oxygen detector and discharge surge tank; Exhaust collection tank top is provided with Water spray head, and the output on described exhaust collection tank top connects photochemical catalytic oxidation deodorizing device by pipeline, and photochemical catalytic oxidation deodorizing device output is connected into discharge surge tank, and discharge surge tank top is provided with delivery pipe; Pipeline between exhaust collection tank and photochemical catalytic oxidation deodorizing device is provided with air and enters pipe, and air enters pipe and is provided with control valve; Ozone detector and oxygen detector are arranged on the pipeline between photochemical catalytic oxidation deodorizing device and discharge surge tank respectively, and ozone detector and oxygen detector divide level signal to be connected into PLC, first output end signal of PLC connects frequency converter and connects photochemical catalytic oxidation deodorizing device by frequency converter, the second output end signal connection control valve of PLC.
As preferably, described exhaust collection tank and air enter between pipe and are provided with dehydrater.
As preferably, described discharge surge tank top is provided with the second Water spray head.
As preferably, the pipeline on rear side of described photochemical catalytic oxidation deodorizing device is provided with delivery pump.
Have employed the hydrogen sulfide odor removal of the synthesis gas tail gas of technique scheme, this hydrogen sulfide odor removal adopts ozone detector and oxygen detector to carry out double check to the gas before discharge surge tank, again for detection data input PLC, then respectively the control valve that frequency converter and air enter pipe is controlled by PLC, the whole system feedback regulation being, automaticity is high, saves energy consumption, prevent photochemical catalytic oxidation deodorizing from surpassing and meet operation, extend its service life.Compared with existing hydrogen sulfide deodorizing method, not only good deodorization effect, and also cost reduces.
Accompanying drawing explanation
Fig. 1: the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment: the hydrogen sulfide odor removal of a kind of synthesis gas tail gas as shown in Figure 1, comprises exhaust collection tank 1, dehydrater 2, photochemical catalytic oxidation deodorizing device 3, delivery pump 4, frequency converter 7, PLC6, ozone detector 60, oxygen detector 61 and discharge surge tank 5.
Bottom exhaust collection tank 1, side connects synthesis gas tail gas, exhaust collection tank 1 top is provided with the first Water spray head 10, the output on exhaust collection tank 1 top connects dehydrater 2, catalytic oxidation deodorizing equipment 3, delivery pump 4 and discharge surge tank 5 successively by pipeline, discharge surge tank 5 top is provided with the second Water spray head 50, and discharge surge tank 5 top is provided with delivery pipe 51.
Pipeline between dehydrater 2 and photochemical catalytic oxidation deodorizing device 3 is provided with air and enters pipe 8, and air enters pipe 8 and is provided with control valve 81.Above-mentioned ozone detector 60 and oxygen detector 61 are arranged on the pipeline between photochemical catalytic oxidation deodorizing device 3 and discharge surge tank 5 respectively, and ozone detector 60 and oxygen detector 61 points of level signals are connected into PLC6, first output end signal of PLC6 is connected frequency converter 7 and is connected the second output end signal connection control valve 81 of photochemical catalytic oxidation deodorizing device 3, PLC6 by frequency converter 7.
During use, synthesis gas tail gas enters exhaust collection tank 1, and ease of solubility gas is dissolved in water, and residual gas, from the output on exhaust collection tank 1 top, first dewaters through dehydrater, then converges with the air air entered in pipe 8 and enter photochemical catalytic oxidation deodorizing device 3.No matter from energy consumption, cost, photochemical catalytic oxidation deodorizing device 3 load and service life, the power and the load that control photochemical catalytic oxidation deodorizing device 3 are very important.Above-mentioned ozone detector 60, oxygen detector 61 detect ozone concentration and oxygen concentration respectively, when ozone detector 60 detects ozone concentration higher than setting value, PLC6 controls frequency converter 7 according to this signal of monitoring, make its photochemical catalytic oxidation deodorizing device 3 power reduction, thus farthest optimize this exhaust treatment system.And oxygen detector 61 detects that the concentration of oxygen diminishes, by the control of PLC6 to control valve 81, increase air inlet, thus prevent air capacity inadequate, cause photochemical catalytic oxidation deodorizing device 3 efficiency low.
