Sampling device for volatile organic compounds in water

Abstract

The invention discloses a sampling device for volatile organic compounds in water. The device comprises a sampling box, and da gas guide pipe is fixedly arranged in the sampling box; a plurality of air outlet holes are annularly formed in the side wall of the air guide pipe at equal intervals from top to bottom; a nitrogen source is fixedly arranged at the top of the sampling box; a gas outlet ofthe nitrogen source is communicated with the upper end of the gas-guide tube through a pipeline; a gas-guide tube is arranged at the top of the sampling box; a collecting device sleeves the upper endof the air guide pipe; an adsorption layer is arranged in the collecting device; two rotating rods are rotationally mounted in the sampling box; a plurality of stirring rods are annularly arranged onthe two rotating rods at equal intervals from top to bottom; a plurality of electric heating rods are annularly arranged in the sampling box at equal intervals. The device utilizes the principle thatnitrogen brings away organic matters in water, violently turns over water through the stirring rod and heats water through the electric heating rod, greatly promotes release of organic matter components in water, combines the organic matter components with nitrogen, effectively improves the sampling efficiency of volatile organic matters in water, and is simple in structure, convenient to use andvery practical.

AI Technical Summary

Benefits of technology

This new technology helps clean up polluted waters by adding electrically-heated rods that help break down harmful substances into smaller particles called solids or liquids. By mixing these materials together before analysis they become more easily dissolved out during subsequent steps like filtration. Additionally, this system includes collectors and sample boxes where there'll be specialized containers made of plastic material used instead of glass tubes when needed. These technical features make them easy to handle while still providing effective removal of contaminants.

Problems solved by technology

This patented technical problem addressed in this patents relates to the contamination caused by volatile organoid chemical substances (VOC) released from different sources like waste treatment plants or manufacturing processes that produce VOCS gas containing harmful gases. These materials can be found throughout our world's waters either directly into these environments or along their routes. Existing methods have limitations in meeting requirements because they require long time periods before reaching equilibrium.
