Abstract
The utility model discloses a kind of ammonium paratungstate production spray column, including spray column, the bottom of the spray column is provided with acid waste gas inlet port, 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 bottom of the spray column is provided with liquid outlet, in the bottom of the spray column, interleaved is provided with some flow-disturbing swash plates successively from the bottom to top, the surface of each flow-disturbing swash plate is coated with exhaust gas catalyst, the pH for the vaporific spray liquid for spraying out by the vaporific spray head is 12~14, the sodium hydroxide of the vaporific spray liquid and the proportioning of water are 1:15~20.The acid waste gas produced during ammonium paratungstate production obtains the waste gas of neutrality, prevents from causing acid waste gas to pollute after effect of the present utility model.
Description
Technical field
The utility model is related 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 is reclaimed.
Utility model content
The purpose of this utility model is that not enough there is provided a kind of ammonium paratungstate production with defect for prior art above-mentioned
Spray column, to solve the above problems.
The technical problem that the utility model is solved 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,
Gas outlet is provided with the top of the spray column, 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 sodium hydroxide 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 is new by this practicality
After the effect of type, the waste gas of neutrality is obtained, prevents from causing acid waste gas to pollute.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of embodiment of the utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
The utility model is expanded on further in face.
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 the vaporific spray liquid 131 of spray out is 12~14, and the sodium hydroxide of vaporific spray liquid 131 and the proportioning of water are 1:15~
20。
Operation principle of the present utility model is as follows：
The acid waste gas produced during ammonium paratungstate production enters the inner chamber of spray column 100 by acid waste gas inlet port 110,
First react and neutralize with 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
The pH of first 130 spray out reacts for 12~14 vaporific spray liquid 131, and the waste gas discharged by the utility model is neutrality,
Prevent from causing acid waste gas to pollute.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
