Problems solved by technology

[0002] The disadvantages of the current dilution technology are: 1. None of the dilution devices used in the field of online water quality analysis on the market has been reported to be able to dilute high-concentration water samples thousands of times
2. The current dilution devices are mostly used in laboratory equipment (such as atomic absorption, atomic fluorescence and mass spectrometry, etc.), which cannot be applied to online monitoring of water pollution sources, and the price is relatively expensive
3. Although some water quality on-line analyzers can dilute high-concentration water samples, the dilution factor is not high and the accuracy is not enough. Therefore, a dilution device for water quality on-line analyzers to measure high-concentration water samples is needed

Abstract

The invention relates to a dilution device for determination of a high-concentration water sample through a water-quality on-line analyzer. The dilution device comprises a dilution sample pipe, wherein the dilution sample tube is communicated with a peristaltic pump A and a sample feeding pipe; a pipe clamping valve A is arranged at the communication part of the dilution sample pipe and the sample feeding pipe; a discharging pipe is arranged on the dilution sample pipe; a pipe clamping valve B is arranged at the top end of the discharging pipe of the dilution sample pipe; a pipeline is communicated with the side wall of the dilution sample pipe; an optical detector is arranged on the pipeline of the side wall of the dilution sample pipe; a peristaltic pump B is communicated with the pipeline of the side wall of the dilution sample pipe; a peristaltic pump C is communicated with the inlet of the sample feeding pipe; an overflow pipe is arranged on the sample feeding pipe; a two-position three-way electromagnetic valve is arranged between the peristaltic pump B and the pipeline of the side wall of the dilution sample pipe. The dilution device has the advantages that the dilution ratio is high, on-line monitoring is realized, and the dilution precision is high.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a dilution device used for an online water quality analyzer to measure high-concentration water samples.
