Description
Technical field
The utility model is related to ammonium paratungstate production system regions, more particularly to a kind of ammonium paratungstate production exhaust-gas treatment system
System.
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.One of step of production ammonium paratungstate is exactly that wolframic acid is decomposed, and current wolframic acid decomposer is big
Majority uses opened type structure, causes waste gas in decomposable process from high air discharge, to pollute environment.
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
Exhaust treatment system, to solve the above problems.
The technical problem that the utility model is solved can be realized using following technical scheme：
Ammonium paratungstate production exhaust treatment system, it is characterised in that including decomposing cell body and spray column, the decomposition cell body
Top be set at the top of sealing top, the sealing and decompose the reactive tank of cell body bottom between space form exhaust dwell
Chamber, temperature detector, pressure detector are provided with the exhaust dwell intracavitary, and the decomposer is set and the temperature in vitro
Be provided with the top of detector, the control device of pressure detector connection, the sealing one connected with the exhaust dwell chamber and
It is provided with what is be connected with the control device on the blast pipe connected with the exhaust gas inlet of the spray column bottom, the blast pipe
Control valve；The top of the spray column is provided with gas outlet, and the inner cavity top of the spray column is provided with vaporific spray head, institute
The bottom for stating spray column is provided with liquid outlet, if interleaved is provided with interference successively from the bottom to top in the bottom of the spray column
Swash plate is flowed, the surface of each flow-disturbing swash plate is coated with exhaust gas catalyst, the vaporific spray for spraying out by the vaporific spray head
The pH of 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 utility model, which will be decomposed, is set to sealing top at the top of cell body, will
The waste gas that reaction is produced carries out centralized recovery discharge, and realizes full automatic working according to pressure and temperature, safe and reliable.In addition
Also waste gas is handled by spray column so that by being neutrality by the waste gas of spray column, prevent 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
