Multi-parameter analysis sample holder

Abstract

The invention discloses a multi-parameter analysis sample holder comprising a water inlet pipeline, a circulation bucket, a drainage pipeline, a sensor, a water outlet valve, an air pump, a sampling pipeline, a sample holding valve, a sampling pump, a sample mixing bucket and a sample holding bottle, thereby analyzing and detecting sewage in a drainage pipe. An inlet valve and a circulation pump are arranged on the water inlet pipeline; the circulation bucket and the water inlet pipeline are communicated via a sampling valve; the drainage pipeline and the circulation bucket are communicated via a pressure release valve; the air pump is connected with the circulation bucket via an exhaust moving valve; the sampling pipe is connected with the water inlet pipeline via the sampling valve; thesample mixing bucket is connected to the tail end of the sampling pipeline; and the sample holding valve and the sampling pump are arranged at the sampling pipeline. The sample holding bottle is communicated with the sample mixing bucket by the sample holding valve. Therefore, the sampling flexibility is improved; the supervision cost is lowered effectively; the supervision level is improved; andthe environmental protection is promoted.

Description

technical field [0001] The invention relates to a sampling device, in particular to a multi-parameter analysis sample retainer for pressure pipeline sampling. Background technique [0002] Since the development of society, environmental protection issues have become increasingly prominent, and relevant departments have become increasingly standardized and strict in the supervision of industrial and mining wastewater discharge. Wastewater is required to be discharged into a unified sewage pipeline through pressure pipes, and then transported to a unified sewage treatment plant for treatment. During this sewage discharge process, it is necessary to sample and analyze the sewage in the pressure pipes in order to better supervise the sewage discharge of enterprises. [0003] The current sampling device either draws a bypass directly on the sewage pipeline to take water samples, but in this way the excess sewage will flow out on the spot, which is not conducive to the environment...

AI Technical Summary

Problems solved by technology

[0003] The current sampling device either draws a bypass directly on the sewage pipeline to take water samples, but in this way the excess sewage will flow out on the spot, which is not conducive to the environment; Additional processing, but there are problems with limited sampling and inflexibility

Once the water sample has been filled in the sample bottle, due to the restriction of the number of sample bottles and the cost of supervision, it is impossible to take water samples during other sewage discharge periods, so there is a technical loophole, which is not conducive to better supervision of sewage discharge
