Online anti-interference NH3-N automatic monitor

Abstract

The invention discloses an online anti-interference NH3-N automatic monitor which comprises a first three-way electromagnetic valve and an ammonia gas collector, wherein a peristaltic pump is arrangedabove one side of the first three-way electromagnetic valve; a metering device is arranged below one side of the peristaltic pump; a valve island is arranged below the metering device; an ejection bottle is arranged on one side, far away from the peristaltic pump, of the metering device; and an ejection tube is arranged above the ejection bottle. Due to adoption of the peristaltic pump, a semi-reflection semi-permeable mirror and the ammonia gas collector, interference of external environment air can be prevented, the ejection rate of the ejection bottle can be increased, the absorption rateof an absorption colorimetric bottle can be increased, a one-time measurement multi-result average value method can be achieved, the measurement stability and accuracy can be ensured, an ammonia-freegas can be provided for a reagent bottle vent hole, the ammonia-free gas can be also provided for the peristaltic pump, external environment interference can be avoided, and relatively good application prospects can be achieved.

Description

technical field [0001] The invention relates to the field of analyzers, in particular to an anti-jamming NH3-N online automatic monitor. Background technique [0002] With the development and progress of society, people have made great achievements in monitoring instruments, and the automatic monitoring instrument is one of the achievements. The automatic monitoring instrument can monitor the monitoring objects in real time by itself, save labor, and improve monitoring speed and accuracy. There are certain drawbacks in the existing automatic monitoring instrument in use, at first, can not isolate the interference of external environment air, can't increase the rate of driving out of the bottle and the absorption rate of the absorption colorimetric bottle, secondly, can not realize once The average method of measuring multiple results cannot guarantee the stability and accuracy of the measurement. In addition, it cannot provide ammonia-free gas to the vent of the reagent bott...

[0002] With the development and progress of society, people have made great achievements in monitoring instruments, and the automatic monitoring instrument is one of the achievements. The automatic monitoring instrument can monitor the monitoring objects in real time by itself, save labor, and improve monitoring speed and accuracy. There are certain drawbacks in the existing automatic monitoring instrument in use, at first, can not isolate the interference of external environment air, can't increase the rate of driving out of the bottle and the absorption rate of the absorption colorimetric bottle, secondly, can not realize once The average method of measuring multiple results cannot guarantee the stability and accuracy of the measurement. In addition, it cannot provide ammonia-free gas to the vent of the reagent bottle, cannot provide ammonia-free gas to the drive of the peristaltic pump, and cannot prevent external environmental interference. The use process has brought a certain impact, for this reason, we propose an anti-jamming NH3-N online automatic monitor
