Description

Water quality ammonia nitrogen online automatic monitor top blast absorption plant
Technical field
The utility model relates to a kind of Water quality ammonia nitrogen monitor, relates in particular to a kind of Water quality ammonia nitrogen online automatic monitor top blast absorption plant.
Background technology
Mensuration for Water quality ammonia nitrogen: ammonia nitrogen (NH3-N) is present in water with free ammonia (NH3) or ammonium salt (NH4+) form, and both ratio of componentss depend on pH value and the water temperature of water.When pH value is higher, the ratio of free ammonia is higher.Otherwise the ratio of ammonium salt is high, water temperature is contrary.
The assay method of ammonia nitrogen mainly contains Na's colorimetry, gas molecule in space absorption process, phenol---hypochlorite (or salicylic acid---hypochlorite) colourimetry and electrode method etc.This section is by article Na's colorimetry and distillation---acidimetry.When water sample band look or muddy and contain some other interfering material, affect the mensuration of ammonia nitrogen.For this reason, when analyzing, need do suitable pre-service.To more clean water, can adopt flocculent precipitation (add appropriate zinc sulfate in water sample, and hydro-oxidation sodium makes alkalize, generate zinc hydroxide precipitation, then remove after filtration color and muddiness); To with serious pollution water or industrial waste water, by the way of distillation, eliminate to disturb (regulating the pH value of water sample to make the scope at 6.0-7.4, adding appropriate magnesium oxide to make into alkalescence, distilling the ammonia discharging and be absorbed in sulfuric acid or BAS.While adopting Na's colorimetry or acidimetry, take BAS as absorption liquid; Adopt salicylic acid---during hypochlorite colourimetry, take sulfuric acid solution as absorption liquid).And in prior art for the complex structure of the top blast absorption plant of Water quality ammonia nitrogen monitor, use inconvenient, make operating process loaded down with trivial details, inefficiency.
Utility model content
The purpose of this utility model provides a kind of Water quality ammonia nitrogen online automatic monitor top blast absorption plant with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises constant flow gas pump, purging device, absorption cuvette, purge solenoid valve and absorption solenoid valve, there are two ports the upper end of described purging device are connected with one end of described absorption solenoid valve with the gas outlet of described constant flow gas pump respectively, the lower end of described purging device is connected with described purge solenoid valve, and the common port of described absorption solenoid valve is connected with described absorption cuvette.
Further, described absorption cuvette is provided with a plurality of channel interfaces.
Particularly, between described constant flow gas pump and described purging device, between described purging device and described absorption solenoid valve and between described absorption solenoid valve and described absorption cuvette, all adopt polyfluortetraethylene pipe to be connected.
The beneficial effects of the utility model are:
The utility model is a kind of Water quality ammonia nitrogen online automatic monitor top blast absorption plant, compared with prior art, the utlity model has simple in structure, easy to operate advantage, can effectively simplify loaded down with trivial details operation steps, and can effectively increase work efficiency, there is the value of promoting the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of Water quality ammonia nitrogen online automatic monitor top blast absorption plant described in the utility model.
In figure: 1-constant flow gas pump, 2-purging device, 3-absorption cuvette, 4-purge solenoid valve, 5-absorb solenoid valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises constant flow gas pump 1, purging device 2, absorption cuvette 3, purge solenoid valve 4 and absorbs solenoid valve 5, there are two ports the upper end of purging device 2 are connected with the one end that absorbs solenoid valve 5 with the gas outlet of constant flow gas pump 1 respectively, the lower end of purging device 2 is connected with purge solenoid valve 4, and the common port that absorbs solenoid valve 5 is connected with absorption cuvette 3.Absorption cuvette 3 is provided with a plurality of channel interfaces.Between constant flow gas pump 1 and purging device, purging device 2 all adopts polyfluortetraethylene pipe to be connected with absorbing between solenoid valve 4 and absorb between solenoid valve 5 and absorption cuvette 3.The utlity model has simple in structure, easy to operate advantage, can effectively simplify loaded down with trivial details operation steps, and can effectively increase work efficiency.
