Description

Ammonium paratungstate production spray column
Technical field
The present invention relates to ammonium paratungstate production apparatus field, more particularly to a kind of ammonium paratungstate production spray column.
Background technology
Ammonium paratungstate (APT) is the important intermediate compound for producing tungsten powder, tungsten filament, tungsten-bast alloy and all tungsten materials, is also Large exporting of China.Acid waste gas can be produced during production ammonium paratungstate, there is presently no to this generation The device that acid waste gas are reclaimed.
The content of the invention
A kind of above-mentioned not enough and defect it is an object of the invention to be directed to prior art, there is provided ammonium paratungstate production spray Tower, to solve the above problems.
Technical problem solved by the invention can be realized using following technical scheme:
Ammonium paratungstate production spray column, including spray column, acid waste gas inlet port is provided with the bottom of the spray column, The top of the spray column is provided with gas outlet, the inner cavity top of the spray column is provided with vaporific spray head, the spray The bottom of tower is provided with liquid outlet, it is characterised in that in the bottom of the spray column, interleaved is provided with successively from the bottom to top Some flow-disturbing swash plates, the surface of each flow-disturbing swash plate is coated with exhaust gas catalyst, the mist for spraying out by the vaporific spray head The pH of shape spray liquid is 12~14, and the NaOH of the vaporific spray liquid and the proportioning of water are 1:15~20.
As a result of technical scheme as above, the acid waste gas produced during ammonium paratungstate production are by of the invention After effect, the waste gas of neutrality is obtained, prevent from causing acid waste gas to pollute.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of an embodiment of the present invention.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, enter below One step illustrates the present invention.
Ammonium paratungstate production spray column shown in Figure 1, including spray column 100, are provided with the bottom of spray column 100 Acid waste gas inlet port 110, gas outlet 120 is provided with the top of spray column 100, and the inner cavity top of spray column 100 is provided with Vaporific spray head 130, the bottom of spray column is provided with liquid outlet 140.In the bottom of spray column 100, interval is handed over successively from the bottom to top Mistake is provided with some flow-disturbing swash plates 210, and the surface of each flow-disturbing swash plate 210 is coated with exhaust gas catalyst, by vaporific spray head 130 The pH of spray vaporific spray liquid 131 out is 12~14, and the NaOH of vaporific spray liquid 131 and the proportioning of water are 1:15~ 20。
Operation principle of the invention is as follows:
The acid waste gas produced during ammonium paratungstate production enter the inner chamber of spray column 100 by acid waste gas inlet port 110, First neutralized with the reaction of the exhaust gas catalyst on the surface of flow-disturbing swash plate 210 when by flow-disturbing swash plate 210, then again with by vaporific spray First 130 spray pH out are that 12~14 vaporific spray liquid 131 reacts, and are neutrality by the waste gas of present invention discharge, are prevented Acid waste gas are caused to pollute.
General principle of the invention and principal character and advantages of the present invention has been shown and described above.The technology of the industry Personnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification this The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appending claims and its Equivalent thereof.
