With reference to shown in Fig. 1 and Fig. 6, the production technology of the device of ammonia process production metallic compound of the present utility model, including
Following steps：
（1）Leaching complex reaction：Raw metal is added to the metal charge area 140 of the leaching tanks, then to leaching
Add ammonium bicarbonate solution in groove, and by reaction gas inlet 120 and circulation pipe 11 to blasting air inside leaching tanks, the air for blasting
After fully being reacted with ammonium bicarbonate solution in circulation pipe 11, it is laggard that escaping gas exports 100 condensations by the reaction gas of leaching tanks
Enter absorption plant 5, solution releases circulation pipe 11 by air and being fully contacted with raw metal carries out complex reaction, and reaction is simultaneously molten
Circulation port 131 of the liquid also by the hole of orifice plate and on disrance sleeve 13 flows into the lower section of orifice plate 15, then by circulation pipe 11
Lower ending opening enters the circular response of circulation pipe 11, up to standard to tenor.
（2）Heat resolve reacts：Obtained in leaching tanks 1 metal ammine complex solution filtering after, selfdecomposition stillpot 3 plus
Material mouth 3111 is added decomposes in stillpot 3, is heated by the heating coil group 34 decomposed in stillpot 3, from air simultaneously
Stirring pipe 33 blasts air, to decomposing the solution stirring in stillpot 3（Metallic compound suspends wherein）, obtained after decomposition
The drain hole outflow of metallic compound selfdecomposition stillpot；
（3）Tail gas absorption：The gas that decomposition reaction is produced in stillpot is decomposed to be inhaled into absorption plant 5 after cooling
Receive.
Hereinafter, by taking the preparation of electron level active copper oxide as an example, the utility model is illustrated：

In entering leachate, for improving solubility and dissolution velocity of the ammonia leaching solution to copper.
Reaction equation is as follows：Cu+2NH4HCO3+2NH3+O2=Cu(NH3)4CO3+2H2O。
（2）Filtered cupric ammine complex solution, is entered by charge door 3111 and decomposes stillpot, is entered by air stirring pipe 33
The air for entering is uniformly distributed through the orifice plate 32 of bottom and carries out bubbling stirring, and cupric ammine complex solution is heated disk in speed heat area 314
Pipe group 34 is heated rapidly（Thermal medium in heating coil group can be steam）, when solution reaches uniform temperature, decompose generation carbon
Sour copper（Or cupric oxide）With mixing ammonia, copper carbonate suspends in the solution under air stirring.Because of the generation of fast decoupled ammonia
A large amount of foams realize froth breaking and gas-liquid separation in froth breaking area 312, it is separated after the blended gas outlet 3100 of mixing ammonia discharge
Mixing ammoniacal liquor is condensed into condenser.The agitating function of the air stirring pipe 33 for decomposing stillpot of the present utility model makes generation
Metallic compound（Copper carbonate）Do not precipitate, while the air for blasting takes away substantial amounts of ammonia when rising, reduce ammonia in liquid
The resistance of volatilization, reduces the possibility that ammonia is generated ammoniacal liquor by solution double absorption.Meanwhile, the first thermal insulation casing 35 and second is protected
Warm sleeve 36 ensure that making full use of for heat.
（3）Gas from leaching tanks 1 enters absorption plant 5, and the condensed device 2 of gas for carrying out selfdecomposition stillpot 3 is condensed,
There is no the mixing ammonia of total condensation into the absorption tower 51 of absorption plant 5, via orifice plate（First orifice plate 5112）It is uniformly distributed
Rise to lower absorbent material（Raschig ring）Laydown area, the aqueous on the absorbing material surface stacked by laydown area in uphill process
Absorb, the water smoke for not having absorbed mixing ammonia to be further atomized the ejection of pipeline 5115 absorbs, and converges in absorption tower bottom
The cooled coil pipe 51211 of mixing ammoniacal liquor cool down, and the ammonia gaseous mixture warp of absorption is not constantly atomized by pump circulation spray absorber
During absorbing material laydown area on second orifice plate 5113 at top, gas-water separation is realized, the part blended gas of mixing ammonia
Outlet enters next absorption tower, is progressively absorbed into ammonia tail gas qualified discharge.Wherein, the suction for being constituted on the absorption tower of multiple series windings
In receiving apparatus, the absorbing liquid of the outflow of absorbing liquid outlet 5120 can be promoted to the absorbing liquid entrance 5114 on the absorption tower as absorbing liquid
Ammonia is absorbed, and the absorbing liquid on absorption tower is exported after 5120 absorbing liquids for flowing out can be lifted from previous absorption tower
Phegma entrance 5101 enters in previous absorption tower, is moistened and ammonia is absorbed with to absorbing material.To ensure
Absorption efficiency, it is one group that absorption tower can set more than 4（Preferably 8）, operating process can be by last absorption tower outlet
Roots blower adjust pressure-fired or tiny structure as needed.General common absorption tower is all the foam absorbing for having press operation
Tower, is not suitable for the technological requirement that ammonia process produces metallic compound.The method of the spray-absorption step by step that the utility model is used, very well
Meet production requirement and environmental requirement.
