The salt content in doctor solution is greatly reduced, but finished product salt but faces that market is limited, market difficult the problem of looking for.Now, more
Coal chemical enterprise tend to desulfurization waste liquor burn acid-making process, which burns after desulfurization waste liquor is concentrated, then produces sulphur
Acid can be fully solved desulfurization waste liquor processing problem.But that there are processes is longer for the technique, invest it is larger, it is limited for scale,
The technique that starts for the insufficient enterprise of operating experience has great difficulty.
Summary of the invention
The utility model provides a kind of acid gas absorption oxidizing tower, and structure is simple, easy to operate, is used for desulfurization waste liquor
The acid gas generated is burned to carry out preparing ammonium sulfate solution after absorption reoxidizes；To on the basis for solving the problems, such as desulfurization waste liquor processing
On, traditional desulfuration waste liquid treatment process process is simplified, equipment investment is saved.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
A kind of acid gas absorption oxidizing tower, including tower body, remained ammonia flusher, filler, redistributor and catalyst layer；
Remained ammonia flusher, multiple filling layers, redistributor and catalyst layer are successively arranged in the tower body from top to bottom；Tower body top
Portion sets clean gas outlet, and the tower body side between lowest level filler and redistributor sets acid gas entrance, and tower body bottom is that sulphur ammonium is molten
Liquid storage tank, the tower body side below catalyst layer, above ammonium sulfate solution storage tank set air intake, ammonium sulfate solution sump bottom side
If ammonium sulfate solution exports.
The remained ammonia flusher is connected by remained ammonia spray line and sprinkler composition, one end of remained ammonia spray line
Remained ammonia conveyance conduit after connecing coal oven dithio-gas condenser, the other end protrude into tower body, are located at the intracorporal remained ammonia of tower
The bottom of spray line is uniformly provided with multiple spray heads.
The catalyst layer uses sulfite oxidation catalyst.
Every layer of wire feeding and material in the multiple filling layers is identical or different, and single layer filler is random packing or regular
Filler, the material of single layer filler are metal, plastics or light porcelain.
Compared with prior art, the utility model has the beneficial effects that
1) acid gas, which absorbs oxidizing tower, can effectively absorb sulfur dioxide and sulfur trioxide in acid gas, reduce atmosphere pollution；
2) acid gas absorbs the process flow and operation difficulty that oxidizing tower substantially reduces desulfurization waste liquor processing, with the prior art
It compares, provides a kind of more effective, economic processing mode；
3) it is provided with redistributor in tower body, liquid phase medium can be made to be evenly distributed in tower, prevents liquid phase medium from generating wall
Stream；
4) gas piping is sent in the prior art before absorbing the cleaned purified gas loopback primary cooler of oxidizing tower via acid gas
Into the coal gas of primary cooler due to containing sour gas, so the equipment of its process and pipeline are required to the heat for carrying out eliminating stress
Processing, to enhance its resistance to corrosion；In the utility model, due to not acid gas-containing in purified gas, so extremely from loopback point
Equipment and pipeline before primary cooler are no longer heat-treated；
5) acid gas absorbs oxidizing tower compact overall structure, not only simplifies technique, saves space, has saved investment, and side
Operation.
