Specific embodiment
For the technical solution of the utility model is more clearly understood, specific embodiment is practical new to this with reference to the accompanying drawing
Type is described further.
As shown in Fig. 1, according to a kind of nitric acid equipment for purifying of the utility model embodiment, including evaporator 1, the steaming
It sends out 1 outer surface of device and is equipped with steam delivery port 11 and steam outlet 12, pass through steam conveying pipe 13 and steam discharge pipe
Road 14 is connected with each other evaporator 1 and purification column 2, and 14 bottom of vapor discharge channel is equipped with valve 121, the valve
121 bottoms are equipped with waste liquid discharge conduit 9, and 9 end of waste liquid discharge conduit is equipped with waste liquid discharge port 91, the top of the purification column 2
Portion is connect by nitric acid vapor pipeline 21 with the first cooler 3, and first cooler 3 is equipped with Waste gas outlet 33, is led to
Crossing first pipe 4 makes to connect at the top of first cooler 3 and bleaching tower 5, and the 5 lower outside surface of bleaching tower is equipped with
Air compressor machine installing port 51,5 bottom of bleaching tower are connect by second pipe 6 with the second cooler 7, and described first is cooling
Device 3 and 7 both ends of the second cooler are symmetrically arranged with cooling water inlet 31 and coolant outlet 32,7 upper surface of the second cooler
Equipped with third pipeline 71, the third pipeline 71 is equipped with nitric acid outlet 72, and 7 bottom of the second cooler is equipped with hydrops
Empty pipeline 73,8 outer surface of nitric acid tank is equipped with nitric acid delivery port 81, and bottom is equipped with nitric acid waste discharge conduit 83, and with it is useless
Liquid discharge conduit 9 connects, and connect the nitric acid tank 8 with purification column 2 by nitric acid pipe 82.
As shown in Fig. 1, when needing to purify to nitric acid using the application, when removing impurity, firstly, closing valve
121, then the nitric acid of required purification is transported in nitric acid tank 8 by nitric acid delivery port 81, the nitric acid in nitric acid tank 8 will
It is flowed by nitric acid pipe 82 in the pipeline of evaporator 1, then air compressor machine is mounted on bleaching tower 5 by air compressor machine installing port 51
On, appropriate cold water is added into the first cooler 3 and the second cooler 7 by cooling water inlet 31, and start condenser, it is quasi-
After ready, steam is imported in evaporator 1 by steam delivery port 11, since steam and nitric acid cannot be contacted directly, because
This, the pipeline in evaporator 1 is all double-layer structure, and nitric acid flows into interior conduit, and the steam imported table on the outside of interior conduit
Face is heated across nitric acid of the interior conduit to its inside, so that it is become steam and is floated up into purification column 2, purification column 2
The interior filtrate being equipped with to nitric acid vapor can filter its internal impurity and float all the way up, pass through when nitric acid vapor passes through
Nitric acid vapor pipeline 21, which enters in the first cooler 3, to be condensed, and nitric acid vapor is made to be converted into nitric acid liquid, generated useless
It abandons and is discharged from Waste gas outlet 33, and the liquid converted is further flowed into bleaching tower 5 by first pipe 4 and is taken off
Color, the air compressor machine in bleaching tower 5 it can be dried filtering decoloration, and temperature is higher in decolorization can reach significant
Effect, nitric acid after being decolourized flows into the second cooler 7 through second pipe 6 to cool down, and can finally be discharged from nitric acid
Mouth 72 collects the nitric acid of purifying, can open valve 121 after purification, and the waste liquid in rapid steamer 1 is passed through waste liquid and is drained
Pipeline 9 is drained from waste liquid discharge port 91, if needing to clear up the second cooler 7, hydrops is emptied on pipeline 73
Valve opening the hydrops inside pipeline can be emptied, it is cleared up later, by this way nitric acid purified
Filter, has reached reduction environmental pollution, has saved the beneficial effect of energy resource.
Above embodiments can be combined with each other in the case where not being antagonistic mutually, further implement.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
