Abstract
The utility model relates to a volatile gas purification and absorption device, specifically to a device for purifying and absorbing volatile gas in a concentrated nitric acid tank, solving the problem that volatile gas in a conventional concentrated nitric acid tank pollutes the environment and erodes equipments. The device comprises an acidic water tank, the lower part of which is connected with an acidic water pump. The outlet of the acidic water pump is connected with an injector, the lower opening of which is inserted in the acidic water tank. In addition, the injector and the concentrated nitric acid tank are connected. The device of the utility model, simple and ingenious in design, easy in operation and good in the effects of purifying and absorbing volatile gas, is a good device for solving environmental problems.
Description
Technical field
The utility model relates to a kind of purifier, is specially a kind of red fuming nitric acid (RFNA) groove Volatile Gas and purifies absorption plant.
Background technology
In red fuming nitric acid (RFNA) is produced, the nitric acid drop that contains high concentration in the red fuming nitric acid (RFNA) groove Volatile Gas, though these nitric acid volatilization gas arbitrarily flow and can not produce tangible harm immediately, but of long duration also can pollute environment, the danger of etching apparatus, and also have problems such as bad processing, and domestic most producer does not cause enough attention and takes resolute control measures to this.
Summary of the invention
The utility model provides a kind of red fuming nitric acid (RFNA) groove Volatile Gas to purify absorption plant in order to solve red fuming nitric acid (RFNA) groove Volatile Gas problem.
The utility model is realized by following technical scheme, a kind of red fuming nitric acid (RFNA) groove Volatile Gas purifies absorption plant, structure comprises acid tank, acid tank below is connected with acid water pump, the acid water delivery side of pump is connected with injector, the end opening of injector inserts in the acid tank, and injector is connected with the red fuming nitric acid (RFNA) groove.
During use, soft water is put into acid tank, the hydraulic pressure in the acid tank is gone in the injector with acid water pump, in injector, produce negative pressure, this part negative pressure sucks red fuming nitric acid (RFNA) groove Volatile Gas in the acid tank, and dissolving in then becomes acid water in the water, continues circulation.Device simplicity of design described in the utility model, ingenious, easy to operate, the Volatile Gas good purification.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-red fuming nitric acid (RFNA) groove, the acid tank of 2-, the acid water pump of 3-, 4-injector
The specific embodiment
As schematically shown in Figure 1, a kind of red fuming nitric acid (RFNA) groove Volatile Gas purifies absorption plant, and structure comprises acid tank 2, acid tank 2 belows are connected with acid water pump 3, the outlet of acid water pump 3 is connected with injector 4, and the end opening of injector 4 inserts in the acid tank 2, and injector 4 is connected with red fuming nitric acid (RFNA) groove 1.
During use soft water put into acid tank 2, with acid water pump 3 hydraulic pressure in the acid tank is gone in the injector 4, in injector, produce negative pressure, this part negative pressure sucks tail gas in the red fuming nitric acid (RFNA) groove 1 in the acid tank 2, dissolve in then and become acid water in the water, with acid water pump 3 hydraulic pressure in the acid tank 2 is gone in the injector 4 again, circulate with this, when acid concentration in the acid tank 2 〉=25%, with acid water pump it is delivered to rare nitric acid workshop section, in acid tank 2, mend soft water then, continue to absorb.
