Embodiment 1
[0039] On the basis of the above-mentioned structure, in this embodiment, the interior of the spray tower 1 is fixedly installed with spray devices 6 and a plurality of packing layers 7 at intervals from top to bottom, the lye inlet communicates with the spray devices 6, and a plurality of The packing layer 7 is located above the exhaust gas inlet, and the bottom of the spray tower 1 is connected to the top of the first section of the reactor 2 through a pipeline; the circulating pump 5 is connected to the part above any packing layer 7 on the spray tower 1 through a return pipe . During the alkali cleaning process, the waste gas containing hydrogen sulfide enters the spray tower 1 from the waste gas inlet at the lower part of the spray tower 1, and continues to rise; at the same time, the waste lye enters the spray device from the lye inlet at the top of the spray tower 1, Spray through the spraying device 6; the waste gas containing hydrogen sulfide contacts and reacts with ...
Embodiment 2
[0043] On the basis of Embodiment 1, in this embodiment, the lower part of the spray tower 1 is fixed with an on-site liquid level gauge 8 by bolts, and the on-site liquid level gauge 8 is located below a plurality of packing layers 7; A remote liquid level gauge 9 is also fixedly installed by bolts, and the remote liquid level gauge 9 is connected with the on-site liquid level gauge 8 . Monitor the liquid level inside the spray tower 1 in real time through the on-site liquid level gauge 8 to avoid excessive liquid level; at the same time, the remote liquid level gauge 9 and the on-site liquid level gauge 8 maintain the same liquid level, that is, the remote liquid level gauge 9 The liquid level is the liquid level in the spray tower 1, and the corresponding liquid level signal is sent to the controller, so that the on-site workers can know the liquid level inside the spray tower 1 in time.
Embodiment 3
[0045] On the basis of the above-mentioned structure, in the present embodiment, the lye inlet is communicated with the lye equipment 10 through the lye pipeline, and the lye equipment can be a box housing the lye, and a delivery pump is installed in the box, and the delivery pump Send the spent lye to the spray tower 1; the lye pipeline, the return pipe, and the pipeline between each circulation pump 5 and the first section of the reactor 2 are respectively connected with maintenance pipes at the parts close to the corresponding spray tower 1 Road one, the inlet and outlet of each=maintenance pipe one are respectively connected on the corresponding pipeline; on each maintenance pipeline one and on the lye pipeline, on the return pipe and the pipe between the circulating pump 5 and one section of the reactor 2 Valves 1 are respectively installed on the positions between the inlet and the outlet of corresponding maintenance pipeline 1 on the road. The maintenance pipeline is co...
