At present, China there is no online acidometer vertification regulation or calibrating standard, context of detection also also exists some problems, measurement technology mechanism calibrates according to JJG119-2005 " laboratory pH(acidity) count vertification regulation ", DL/T677-2009 " generating plant on-line chemical monitoring instrument inspection procedure " mostly, accurately consistent in order to ensure the value of online acidometer, meet the needs of all trades and professions, the calibrating installation developing a set of online acidometer is imperative.
Summary of the invention
The purpose of this utility model is by the measurement and calibration to online acidometer, and the applying unit for online acidometer provides the measurement data of fair and accurate, and spy provides a kind of calibrating installation of online acidometer.
The utility model provides a kind of calibrating installation of online acidometer, it is characterized in that: the calibrating installation of described online acidometer comprises the clean container that five volumetric standards that standard buffer solution is housed and are equipped with cleaning fluid, described volumetric standard is connected with downward-sloping main line with flowmeter by solenoid valve, described clean container is connected with downward-sloping main line by solenoid valve, the position that the position that described clean container is connected with main line is connected with main line higher than described volumetric standard, the upper end Bonding pressure controller of main line and air pump, air pump is connected on nitrogen cylinder by flexible pipe, the lower end of main line is connected on the online acidometer that is calibrated, online acidometer is connected with waste fluid container by solenoid valve.
As preferred technical scheme, also comprise singlechip controller, the port of described singlechip controller is connected with solenoid valve, flowmeter by bus.
As preferred technical scheme, the angle of inclination of described main line is 20 degree, and main line is that acidproof, corrosion resistant UPVC manages.
Advantage of the present utility model:
The calibrating installation of online acidometer described in the utility model can realize the calibration to online acidometer, and calibration process is simply easy to operation, and calibration result is accurate, reliable, has certain practicality.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is a kind of calibrating installation theory structure schematic diagram of online acidometer.
In figure, 1-clean container, 2-volumetric standard, 3-volumetric standard, 4-volumetric standard, 5-volumetric standard, 6-volumetric standard, 7-solenoid valve, 8-flowmeter, 9-nitrogen cylinder, 10-air pump, 11-pressure controller, 12-main line, the online acidometer of 13-, 14-waste fluid container.
Embodiment
The utility model provides a kind of calibrating installation of online acidometer, in order to have higher accuracy of measurement, calibrating installation comprises the volumetric standard 2,3,4,5,6 that five are equipped with standard buffer solution, the volume of volumetric standard 2,3,4,5,6 is 2000mL, standard buffer solution pH value 25 DEG C time is respectively 4.00,6.86,7.00,9.18,10.01, can realize the calibration of the online acidometer of different pH value.
Because there being different pH value standard buffer solution to calibrate online acidometer 13, the situation of different pH value standard buffer solution cross pollution is there is in calibration process, therefore higher requirement is proposed to the clean of signal piping, and reduce as far as possible due to the unclean of pipeline the impact that calibration data produces.The calibrating installation of online acidometer also comprises clean container 1 and nitrogen purging device that one is equipped with cleaning fluid, improve accuracy of detection to a certain extent, when using a kind of standard buffer solution, the remaining a part of liquid of meeting in pipeline, upper a kind of standard buffer solution in pipeline cleans up by cleaning fluid, the position that the position be connected with main line 12 due to clean container is connected with main line 12 higher than described volumetric standard, and the angle of inclination of main line 12 is 20 degree, opens solenoid valve 7, flowmeter 8 only needs self gravitation standard buffer solution and cleaning fluid can be flowed out, both the energy had been saved to a certain extent, the hazard level reduced in testing process because of having used power equipment less again.But because the existence of cleaning fluid also can exist impact to measurement result, so enable nitrogen purging procedure, open nitrogen cylinder 9, open air pump 10 and pressure controller 11, the controlled rapid purging of flow velocity is carried out to pipeline, pipeline through purging is dry and clean, just can carry out the measurement of next pH value afterwards.In a calibration process, online acidometer 13 is connected by solenoid valve 7 with waste fluid container 14, according to calibration situation, the buffer solution calibrated and cleaning fluid can be collected waste fluid container 14, therefore, can be called the calibration process cleaned simultaneously.
Whole calibration process also comprises singlechip controller, the port of singlechip controller is connected with solenoid valve 7, flowmeter 8 by bus, achieve the flow control of switch control rule to each solenoid valve 7 and flowmeter 8, achieve different in flow rate, different pH value, the calibration of the online acidity tester of various different manufacturers can be adapted to.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
