Description
Technical field
The utility model relates to nitric acid production equipment, specifically a kind of colourless concentrated nitric acid production system.
Background technology
At present, nitric acid adopts double pressurized method production, and it is 65% nitric acid that maximum concentration can only produce concentration, and contains relatively large oxides of nitrogen gas in the acid, so that made nitric acid is yellow.At present concentration is that 98% concentrated nitric acid adopts indirect denitration method to produce, and after the magnesium nitrate dewatering agent dewaters, produces the concentrated nitric acid that meets national standard with rare nitric acid.But, in the actual production, produce the needed concentration of some Chemicals and be about 70% colourless nitric acid, at home also not preferably production unit and method.
The utility model content
The purpose of this utility model will provide a kind of colourless concentrated nitric acid production system exactly, to realize the purpose of the colourless concentrated nitric acid of direct production, meets the need of market preferably.
The utility model is achieved in that
Colourless concentrated nitric acid production system comprises:
One retort with measuring apparatus is provided with bulging air-coil in tank body, described bulging air-coil has pore;
One compressed air inlet pipe is used for sending into pressurized air in described bulging air-coil;
One concentrated nitric acid input tube is used in described retort tank body input concentration and is 98% concentrated nitric acid;
One acid adding pump is used in described retort tank body input concentration and is 60% nitric acid;
One oxynitride fairlead is used for the oxynitride that produces in the described retort tank body is drawn;
One cyclic acid pump, the input terminus of described cyclic acid pump joins by intake line and the outlet of described retort tank body lower part, described recycle acid delivery side of pump joins by delivery conduit and described retort tank body upper inlet, is used for making the mixing acid circulation in the described retort tank body; Be provided with at described delivery conduit and adopt sour arm, described adopt to be provided with on the sour arm adopt sour valve;
And an oxynitride washing system, be used for receiving the oxynitride that described oxynitride fairlead draws and carry out carrying out washing treatment.
Described oxynitride washing system comprises:
The oxynitride washing tower;
And the oxynitride cleaning circulation pump, be used for making the liquid circulation in the oxynitride washing tower; The input terminus of described cyclic acid pump joins by intake line and described oxynitride washing tower lower part outlet, described oxynitride cycles of washing delivery side of pump joins by delivery conduit and described oxynitride washing tower upper inlet, is used for making the liquid circulation in the oxynitride washing tower; Be provided with sour water extraction pipe at described delivery conduit, be provided with valve on the described sour water extraction pipe.
The utility model adopts this structure, will squeeze in the retort with measuring apparatus through the acid adding pump from 60% nitric acid of dilute nitric acid production device, gets to suitable scale value in the tank, termination of pumping.Compressed air inlet pipe is used for sending into the pressurized air that pressure is 0.3MPa in described bulging air-coil, and the pore of offering through described bulging air-coil outwards blows out.98% concentrated nitric acid from the production of concentrated nitric acid device is inputted in the described retort tank body by the concentrated nitric acid input tube.In the retort tank body, the oxynitride tobacco that overflows when two kinds of acid of 60% nitric acid and 98% concentrated nitric acid mix is introduced the processing of oxynitride washing system by the Air blowing that bloats in the coil pipe via the oxynitride fairlead.Mixing acid in the retort circulates through cyclic acid pump, until acid becomes colorless when transparent by yellow, is 70% nitric acid through adopting sour valve extraction concentration.
The utility model is 70% nitric acid for the production of concentration, and operation is succinct, production cost is low, good product quality, and fully satisfying the market is the user demand of 70% nitric acid to concentration.
