Rotten agent etc..
The production technology metering of existing ammonium acid fluoride is accurate not, result in reaction unstable completely, easily causes dirt
Dye, and reaction controllability is low, product quality is difficult to meet electron level demand.
Summary of the invention
For overcoming the problems of the prior art, the invention provides a kind of metering accurately, stable reaction is complete, does not results in
Polluting, and reaction controllability is high, product quality disclosure satisfy that production equipment and the technique thereof of the ammonium acid fluoride of electron level demand.
Technology and method in order to solve the employing of the above-mentioned problem present invention are as follows:
A kind of production equipment of ammonium acid fluoride, include AHF measuring tank, AHF dosing pump, AHF gasifier, ammonia surge tank,
NH3Filter, NH3Heater, steam distributor, reactor, pelleter, glass fibre reinforced plastics cooling tower and packaging facilities, described AHF counts
Measuring tank, AHF dosing pump and AHF gasifier are sequentially connected with, described ammonia surge tank, NH3Filter and NH3Heater is sequentially connected with, institute
State AHF gasifier and NH3Heater is connected with steam distributor respectively, described steam distributor, reactor, pelleter, glass
Steel cooling tower and packaging facilities are sequentially connected with, and described reactor is connected with air stove and hot air circulation blower, described reactor, hot blast
Stove and hot air circulation blower circulate connection successively.
Another technical problem that the invention solves the problems that, for providing the production technology of a kind of ammonium acid fluoride, comprises the following steps:
Fluohydric acid gas AHF in AHF measuring tank is sent in AHF gasifier via AHF dosing pump and carries out gasification process, then
Send in reactor via steam distributor；
2) by the gas ammonia NH in ammonia surge tank3Via NH3NH sent into by filter3Heater is carried out under the regulation of 100 DEG C
The pre-heat treatment, then sends in reactor via steam distributor；
3) steam distributor is passed through fluohydric acid gas AHF and gas ammonia NH according to mass ratio 2:13To reactor, it is concurrently accessed heat
Wind furnace and hot air circulation blower, air stove is 300 DEG C with the temperature of hot air circulation blower；
4) at fluohydric acid gas AHF and gas ammonia NH3The object produced after reaction is put into and is carried out film-making in pelleter, then via glass
Glass steel cooling tower is cooled to room temperature, puts into packaging facilities intermediate package molding.
The invention have the benefit that anhydrous hydrogen fluoride gas and ammonia are passed through direct reaction in reactor, use import
Equipment accurate measurement, stable reaction is complete, does not the most pollute, does not has side-product；Owing to using Advanced Control Techniques, instead
Answering controllability high, produce stable, therefore product quality can meet electron level needs.
