Description
Technical field
The utility model relates to the production that hypochlorous acid is received, and in particular, it relates to the detection of sodium hypochlorite effective chlorine in sodium hypochlorite production run.
Background technology
Sodium hypochlorite is a kind of high-efficient oxidant and chlorine-containing disinfectant, is used for papermaking, weaving, light industry etc., has the effect of bleaching, sterilization, sterilization as bleaching agent, oxygenant and water scavengine agent.Its oxidability is strong, it is fast, effective to act on, and its effect is very extensive.Its preparation method mainly contains saline electrolysis, chlorine and NaOH contact reaction.Need to detect the effective chlorine in reaction in the middle of hypochlorous acid receives production run, existing existing equipment for producing sodium hypochlorite effective chlorine detection method is that hand labor workload is large by analyzing work titrimetry per hour 1 time, analyzes interval time long, sodium hypochlorite quality fluctuation is large, unstable.
Utility model content
According to the deficiencies in the prior art, the utility model provides a kind of hypochlorous acid and receives pick-up unit, for carrying out continuous detecting to the effective chlorine before and after the reaction in pipeline in the middle of chemical industry, thus judge that whether sodium hypochlorite quality is qualified, and reducing hand labor workload, working stability, accuracy in detection are high.
For achieving the above object, the utility model provides following technical scheme: a kind of hypochlorous acid receives pick-up unit, comprise the first pipeline and the second pipeline that removably connect with pipeline to be detected, described first pipeline and the second pipeline and line connection to be detected have sealing ring, the end of described first pipeline and the second pipeline is provided with screen pack, described screen pack extends to channel interior to be detected, also comprise orp detecting device, described orp detecting device has the inert electrode being positioned at the first branch road and the contrast electrode being positioned at the second branch road.
Further, described inert electrode is platinum electrode.
Further, described contrast electrode is mercurous chloride electrode or silver-silver chloride electrode.
Further, described first pipeline is connected with pipeline to be detected by flange with the second pipeline.
The beneficial effects of the utility model are, in sodium hypochlorite, chlorion has strong oxidizing property, available chlorine content is higher, its oxidisability will be stronger, accepting electronic capability also can be stronger, therefore the potential difference (PD) recorded by ORP just can draw the content of sodium hypochlorite effective chlorine, and removably connected and pipeline to be detected by the first pipeline and the second pipeline, screen pack stretches in pipeline to be detected, screen pack can get rid of the interference of impurity in the middle of solution, and the first pipeline and the second pipeline and line connection to be detected have sealing ring and reach the leakage avoiding detecting solution.
Accompanying drawing explanation

Fig. 2 is that a kind of hypochlorous acid of the utility model receives the another kind of schematic diagram of pick-up unit.
Description of reference numerals: 1, pipeline to be detected; 2, film-falling absorption tower; 3, the first pipeline; 4, the second pipeline; 5, screen pack; 6, flange; 7, orp detecting device; 71, inert electrode; 72, contrast electrode.
Embodiment
Receive pick-up unit with reference to a kind of hypochlorous acid of accompanying drawing 1 to the 2 pair of the utility model to be described further.
A kind of hypochlorous acid receives pick-up unit, comprise the first pipeline 3 and the second pipeline 4 removably connected with pipeline 1 to be detected, pipeline to be measured is the pipeline of chemical plant film-falling absorption tower 2 both sides, NaOH is connected with in the first pipeline 3, NaOH in first pipeline 3 to enter in film-falling absorption tower 2 and passes into chlorine, with pipeline 1 junction to be detected, there is sealing ring 6 at described first pipeline 3 and the second pipeline 4, the end of described first pipeline 3 and the second pipeline 4 is provided with screen pack 5, the material of screen pack 5 is rigid, serve in pipeline 1 to be detected not yielding, screen pack 5 can get rid of the interference of impurity in the middle of solution, reach Detection results more accurate, it is inner that screen pack 5 extends to pipeline 1 to be detected, also comprise orp detecting device 7, orp detecting device 7 has the inert electrode 71 being positioned at the first branch road and the contrast electrode 72 being positioned at the second branch road, described inert electrode 71 is platinum electrode, contrast electrode 72 is mercurous chloride electrode or silver-silver chloride electrode, orp detecting device 7 is connected with conputer controlled machine, the feedback data recorded is transferred in the middle of conputer controlled machine, orp detecting device 7 is prior art well known in the art, therefore the no longer central concrete expansion of the present embodiment, first pipeline 3 is connected by flange 6 with the second pipeline 4, O-ring seal is arranged on the flange face that is connected.
The essence of redox reaction is the transfer of electronics.It is stronger that material connects nucleophobic tendency its oxidisability larger, this material i.e. strong oxidizer.Providing the larger material of electronics tendency is on the contrary exactly strong reductant, the power of reductant-oxidant can compare by measuring its size accepting (or providing) electronics tendency, and the potential difference (PD) measuring electrode and the contrast electrode 72 be made up of oxidation-reduction pair can be learnt.In sodium hypochlorite, chlorion has strong oxidizing property, available chlorine content is higher, its oxidisability will be stronger, accepting electronic capability also can be stronger, therefore the potential difference (PD) recorded by ORP just can draw the content of sodium hypochlorite effective chlorine, and removably connected and pipeline 1 to be detected by the first pipeline 3 and the second pipeline 4, screen pack 5 stretches in pipeline 1 to be detected, screen pack 5 can get rid of the interference of impurity in the middle of solution, and the first pipeline 3 and the second pipeline 4 have sealing ring 6 with pipeline 1 junction to be detected and reach the leakage avoiding detecting solution.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
Although more employ the terms such as pipeline to be detected, film-falling absorption tower, the first pipeline, the second pipeline, screen pack herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
