A layered extraction sampling device for filterable wastewater on-line monitoring

Abstract

The invention provides a layered extraction sampling device box for filterable waste water online monitoring. The layered extraction sampling device box comprises a sampling tube, wherein the inner wall of the sampling tube is fixedly provided with a first clamping groove in the length direction; a gear plate is arranged in the first clamping groove in a clamped way. In the use process, when the tail part of a ratchet plate is pressed, the ratchet plate is disengaged from a regulating gear; the regulating gear can vertically slide through being clamped by a second clamping groove; sampling cups are driven to vertically slide; the positions of the sampling cups can be freely regulated; when the tail part of the ratchet plate is released, the head part of the ratchet plate clamps the regulating gear; the positions of the sampling cups are fixed; the sampling tubes slowly extend into waste water; pressure is exerted onto a pressing device; a traction rope contracts; a tube cover is opened; the waste water in each layer enters each of the installed sampling cup; the pressing device is released; the tube cover is closed; the continuous entering of the waste water is prevented; the sampling tube is lifted up; a rubber plug arranged at the lower part of the sampling tube is opened; the sample is collected and is put into an on-line monitoring analysis instrument for analysis.

Description

technical field [0001] The invention relates to the technical field of waste water and waste gas detection, in particular to a high-efficiency waste water and waste gas online monitoring device that can be collected in multiple places. Background technique [0002] With the continuous enhancement of human awareness of environmental protection, factories have higher and higher requirements for the discharge of waste water. A large amount of waste water and waste gas will be generated in the process of industrial chemical production. It is necessary to extract samples from the waste water, analyze the waste water with a water quality analyzer, and then analyze the waste gas in the waste water to obtain the components in the waste water and waste gas and the content of various pollutants, and carry out the analysis of the waste water and waste gas that does not meet the standards. Strictly handle until the discharge standard is met. At present, the existing waste water and was...

AI Technical Summary

Problems solved by technology

[0003] 1. The treatment of wastewater before testing is not perfect, dirt is formed on the surface of the sampling pipeline, and large particles of impurities are inevitably mixed in the wastewater, which is easy to block the pipeline and affect water quality analysis;

[0004] 2. The degree of automation is not high, and the pollutant content in the wastewater cannot be detected one by one at the same time, resulting in slower detection efficiency;

[0005] 3. The content of pollutants in the waste water varies from place to place in the waste water pool. The existing waste water and waste gas monitoring devices cannot collect waste water in multiple places, which affects the accuracy of waste water monitoring.
