Description
Technical field
The utility model relates to detection technique and environmental analysis field, particularly a kind of two electrode segment measuring cells of acid rain on-line continuous automonitor.
Background technology
Environment supervision instrument is the instrument general name for monitoring indoor and outdoor surroundings parameters, by on the mensuration of typical value affecting environmental quality factor, determine environmental quality (or pollution level) and variation tendency thereof, comprising acid rain on-line monitoring instrument.
The formal title of acid rain is acid deposition, it can be divided into " wet deposition " and " dry deposition " two large class, the former refers to all vaporous pollutants or particulate contaminant, fall earthward along with precipitation kenels such as rain, snow, mist or hails, latter refers to the date do not rained, from the dust fall lowered in the air with acidic materials.The acid rain of China is mainly formed because of the high coal of a large amount of combustion of sulfur amount.Acid rain can cause soil acidification; Direct infringement can be caused to plant leaf blade, leaf chlorosis is turned yellow and starts to come off; Non-metallic Building Materials (concrete, mortar and Dinas brickes) Surface hardened layer cement can be made to dissolve, occur cavity and crack, cause intensity to reduce, thus building damage, huge infringement is produced to environment.
Up to the present, Environmental Protection in China instrument manufacturer facility man proposes multiple solution to the sampling of acid rain and monitoring, and produce various types of acid rain monitoring instrument, but normally work in more severe outdoor climate conditions because structure, principle all meeting instrument, and the problems such as the situation of change of sample in settling process can not be reflected really, cause automatic acid rain monitor to be obstructed on promoting the use of.Chinese patent 201120107365.6 discloses a kind of acid rain monitoring umbrella, utilizes pH value colorimetric card and supporting pH test paper to carry out acid rain monitoring, still can not meet at the normal requirements of one's work of severe outdoor climate conditions.
Summary of the invention
The utility model proposes a kind of two electrode segment measuring cells of acid rain on-line continuous automonitor, solve in prior art and normally work in more severe outdoor climate conditions because structure, principle all meeting instrument, and the problems such as the situation of change of sample in settling process can not be reflected really.
The technical solution of the utility model is achieved in that
A kind of two electrode segment measuring cells of acid rain on-line continuous automonitor, comprise: housing, pH sensor, conductivity sensor, described housing has stair-stepping V-type bottom surface chamber, described V-type cavity bottom offers tapping valve, and housing side offers the liquid feed valve and air-vent that communicate with chamber; Described pH sensor and conductivity sensor are installed on two tops of the V-type bottom surface chamber of housing respectively.When detected water sample flows through pH sensor, conductivity sensor surface, after in water sample, pH value and electric conductivity value are measured rapidly, measuring cell discharges residual water sample fast, not easily remains.
Further, described housing also offers the flushing port communicated with chamber and blowback hole.
Further, described housing is provided with liquid level sensor, described sensor probe lays respectively at top and the bottom of housing.The probe being positioned at top is the high liquid-level probe detecting the highest liquid level of water sample; The probe being positioned at bottom is the low liquid-level probe detecting water sample minimum liquid level; Also comprise the public probe being positioned at bottom; To the controller that the signal of liquid-level probe output amplifies and detects, when fluid to be measured reaches action probe, controller exports high or low level signal, coordinates relay, thus realizes Liquid level.
Further, the probe of described liquid level sensor is inert metal probe, and its controller is single-chip microcomputer.
Further, described liquid feed valve is two logical motorized valves.
Further, described tapping valve is two logical motorized valves.
Further, described measuring cell is made up of transparent material.
The beneficial effects of the utility model are:
(1) measuring cell bottom surface is V-shaped, tapping valve at the bottom of " V " shape electrode cell bottom.Can discharge residual water sample fast, not easily remain, detection speed is fast, and simple to operate, non-secondary pollution, is convenient to production and processing and installation and maintenance.(2), in settling process, the on-line measurement wet deposition sample of contiguous segmentation, reflect the pH value of wet deposition sample, the electric conductivity value situation of change with settling process really, data are more accurate.
