Description
Technical field
The present invention relates to ammonium paratungstate production apparatus field, more particularly to a kind of modified form ammonium paratungstate decomposer.
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.The one of step for producing ammonium paratungstate is exactly that wolframic acid is decomposed, and current wolframic acid decomposer is big
Majority uses opened type structure, and waste gas pollutes environment from air discharge high in causing decomposable process.
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 modified form ammonium paratungstate point
Solution groove, to solve the above problems.
Technical problem solved by the invention can be realized using following technical scheme：
Modified form ammonium paratungstate decomposer, including decompose cell body, it is characterised in that it is set at the top of the decomposition cell body
Sealing top, space forms exhaust dwell chamber between the sealing top and the reactive tank for decomposing cell body bottom, and the waste gas stops
Stay in chamber that interleaved is provided with some spoilers successively from the bottom to top, the surface of the spoiler is coated with exhaust gas catalyst,
Temperature detector, pressure detector are provided with the exhaust dwell chamber, the decomposer sets examined with the temperature in vitro
Survey device, the control device of pressure detector connection, be provided with sealing top one connected with the exhaust dwell chamber and with
The blast pipe of waste gas recovering device connection, is provided with the control valve being connected with the control device on the blast pipe.
As a result of technical scheme as above, the present invention will decompose and sealing top be set at the top of cell body, will react
The waste gas of generation carries out centralized recovery discharge, and realizes full automatic working according to pressure and temperature, safe and reliable.Furthermore, when
Waste gas is first neutralized when exhaust dwell chamber stops with the exhaust gas catalyst reaction on spoiler, reduces acidity when waste gas is discharged.
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.
Modified form ammonium paratungstate decomposer shown in Figure 1, including cell body 100 is decomposed, the top for decomposing cell body 100 sets
Sealing top 110 is set to, space forms exhaust dwell chamber between sealing top 110 and the reactive tank 120 for decomposing the bottom of cell body 100
130.Interleaved is provided with some spoilers 131 successively from the bottom to top in exhaust dwell chamber 130, and the surface of spoiler 131 applies
Exhaust gas catalyst is covered with, when waste gas is stopped in exhaust dwell chamber 130, in the exhaust gas catalyst reaction first and on spoiler 131
With acidity when reduction waste gas is discharged.Temperature detector 210, pressure detector 220 are provided with exhaust dwell chamber 130, point
Solution cell body 100 sets outward the control device 300 being connected with temperature detector 210, pressure detector 220.Set on sealing top 110
A blast pipe 400 for being connected with exhaust dwell chamber 130 and being connected with waste gas recovering device 500 is equipped with, is provided with blast pipe 400
The control valve 410 being connected with control device 300.
Operation principle of the invention is as follows：
The waste gas that the reaction of reactive tank 120 is produced is detained in the exhaust dwell chamber 130 after rising, when temperature detector 210,
After the air pressure and temperature that pressure detector 220 is detected in exhaust dwell chamber 130 reach predetermined parameter, control device 300 is controlled
Control valve processed 410 is opened so that the waste gas in exhaust dwell chamber 130 is concentrated from blast pipe 400 and is expelled to waste gas recovery dress
500 are put to be recycled.
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.
