Description
Technical field
A kind of nitric acid waste gas condensation processing system is the utility model is related to, belongs to technical field of waste gas treatment.
Background technology
Nitric acid waste gas is a kind of waste gas common in industrial production, multiple for nitric acid waste gas generally use in industry at present
The technique of alkali lye spray, the purpose is to lengthen the time of waste gas neutralization, nitric acid, this work are handled using the characteristic of acid-base neutralization
Skill usually requires the equipment such as 2~3 scrubbing towers, supporting water pump, spray system, filler, and investment is big, and effect is unstable, and runs
Expense and management cost are higher.
By taking the moving back and hang process of electroplating industry as an example, need to heat due to moving back extension, generally the temperature in plating cylinder face can reach
70~80 degrees Celsius, the process treatment time length of use multiple alkali lye spray in the prior art, at a temperature of slow down, be unfavorable for liquid
Change, it is necessary to be improved.
Utility model content
Technical problem to be solved in the utility model is：A kind of nitric acid waste gas condensation processing system is provided, to solve
The defects of nitric acid waste gas treatment equipment cost of the prior art is high, and treatment effeciency is not high.
In order to solve the above technical problems, the utility model proposes technical scheme be：A kind of nitric acid waste gas condensation processing system
System, including spray scrubber, it is characterised in that：Spray scrubber only has a set of in the nitric acid waste gas condensation processing system；It is described
Nitric acid waste gas condensation processing system also include cooling cylinder and refrigerator, before described cooling cylinder is arranged on spray scrubber, and
It is connected with the spray scrubber by pipeline technology；The cooling cylinder is used to condense nitric acid waste gas, described used for refrigerator in shape
The circulation of refrigerant in into the cooling cylinder.
As further optimization, described cooling cylinder is condensed using water cooling, and condenser pipe uses titanium tube.
As further optimization, described cooling cylinder also includes collector tube, and described collector tube connects with cooling cylinder bottom.
Using a kind of nitric acid waste gas condensation processing system described in the utility model, first nitric acid waste gas is carried out at condensation
Reason, makes it cause temperature to decline to a great extent in the short time, advantageously in liquefaction, plating is produced and produces beneficial effect, passed through
The nitric acid waste gas of condensation process is thoroughly neutralized by one of spray scrubber again, and treatment effeciency is high, effect is good, using the party
Case only needs a set of spray scrubber, reduces cost of investment, solves the defects of prior art is present.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one of which specific embodiment；
In figure mark for：Refrigerator 1, cooling cylinder 2, spray scrubber 3, collector tube 4.
Embodiment
Below in conjunction with the accompanying drawings, further detailed description is carried out to the technical solution of the utility model, in following description
In elaborate many details in order to fully understand the utility model, but the utility model should not be restricted by following public tool
The limitation of body embodiment.
As shown in figure 1, a kind of nitric acid waste gas condensation processing system, including spray scrubber 3, it is characterised in that：Spray is washed
It is only a set of to wash tower 3, nitric acid waste gas condensation processing system also includes cooling cylinder 2 and refrigerator 1, and cooling cylinder 2 is arranged on spray and washed
Before washing tower 3, it is connected with spray scrubber 3 by pipeline, the cooling position of refrigerator 1 is close to cooling cylinder 2；Cooling cylinder 2 is used for
Nitric acid waste gas is condensed, refrigerator 1 is used for the circulation for forming refrigerant in cooling cylinder 2.Cooling cylinder 2 in this preferred embodiment is to use
Water cooling condensation, condenser pipe use titanium tube, and the cooling cylinder 2 in this specific embodiment also includes collector tube 4, collector tube 4 and condenses
The bottom of case 2 connects.
Using the described nitric acid waste gas condensation processing system in this specific embodiment, using the volatility of nitric acid, use
The mode of condensation liquefaction, the nitrogen oxides in the nitric acid waste gas of high concentration is liquefied, so as to which the nitric acid being greatly reduced in waste gas is dense
Degree, end are neutralized absorption to remaining tail gas using traditional spray mode again, first the nitric acid through collection are given up during use
Gas carries out rapid cooling by cooling cylinder 2, makes it cause temperature to decline to a great extent in the short time, the quick liquid of nitric acid molecule in waste gas
Change, the waste liquid after liquefaction is collected again, and outward transport is handled after being exported by collector tube 4 or recycling, the low concentration after cooling give up
Gas neutralizes the acidic molecular of residual again by alkali lye spray process, realizes purification process, the work of refrigerator 1 in processing procedure
With being the continuous recirculated cooling water for providing low temperature, the described nitric acid waste gas condensation processing system processing effect in this specific embodiment
Rate is high, effect is good, only needs a set of spray scrubber 3, a set of cooling cylinder 2 and a set of refrigerator 1, reduce investment and run into
This, solves the defects of prior art is present.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model, the scope of protection of the utility model should with power
Protection domain described by sharp claim is defined.
