Abstract
This invent is classified as in the category of natural resources and environment technology. It is a device for trapping ebullition from waters and its application. This device includes a floating frame hanging a dome connected to a storage bottle via a two-way stopcock and tube at the top. The storage bottle is hanged upside down on to the frame top cent. The bottle is a narrow necked polypropylene having a rubber stop fixed with two glass tubes and two latex tubes, one tube for collecting bubbles and the other for water drainage.
To put the device in operation, follow the steps below:
1. Connect the T shaped bolt with the two-way valve first, then hang the dome to the floating frame.
2. Place (anchor) the frame and dome to the ebullition site, then open the two-way valve, and submerge the dome into water totally so that all the air in the dome and tube is evacuated, then close the valve.
3. Connect pre-filled (pure water) bottle to the gas inlet and drainage latex tube (also filled with water and clamped at the end).
4. Invert and hang the bottle to the top of the frame.
5. Connect two-way valve to the gas inlet latex tube, then release the clamp.
6. Put the water drainage tube into water and release the clamp.
Gas ebullition is collected via the floating dome. When gas accumulates in the dome, differential pressure, created by leveled drainage water, makes the gas continuously and automatically entering the storage bottle, which is ready for measuring (in volume), calculating ebullition rates and analyzing its composition.
This invent provides a automatic, fast and convenient, accurate and precise way to estimate gaseous emission of ebullition including CH4, CO2, O2, N2O and especially N2, which, otherwise, is difficult to estimate due to high concentration of N2 in the air.
To put the device in operation, follow the steps below:
1. Connect the T shaped bolt with the two-way valve first, then hang the dome to the floating frame.
2. Place (anchor) the frame and dome to the ebullition site, then open the two-way valve, and submerge the dome into water totally so that all the air in the dome and tube is evacuated, then close the valve.

Description
DEVICE FOR SAMPLING EBULLITION AND SAMPLING METHOD
Category This invent is classified as in the category of natural resources and environment technology. It is a device for trapping ebullition from waters and its application.
Technical Background Global warming, draws the attention to estimate emissions of greenhouse gases, especially carbon dioxide, methane and nitrous oxide. Rivers, lakes, reservoirs and costal marine ecosystems are important sources of emission of greenhouse gases. On the other hand, scared water resources attracted the interests to understand nitrogen transport in water ecosystems.
It is often desired to remove nitrogen (N-NH4, N -N03) from water for water reclamation. Further more, removing nitrogen, and other plant nutrition, from a water body also helps to keep the ecosystem healthy.
An inverted funnel is often deployed to trap methane bubbles from sediment since 1776.
However, the application of the inverted funnel is not convenient, easily introducing errors and cumbersome, which makes the research and investigation difficult.
Invent Details This invent provides a automatic, fast and convenient, accurate and precise way to estimate gaseous emission of ebullition including CH4, C02, 02, N20 and especially N2, which, otherwise, is difficult to estimate due to high concentration of N2 in the air. The procedures of its method are extensively explained.
The floating frame is made of two galvanized iron thread, banded in a bow shape, 900 cross welding together. The frame height is 400 mm with a square shape bottom, at a length of 500 mm each side. The floating balls are of enforced foam with 100 mm in diameter.
The storage bottle is of polypropylene with a narrow neck sealed by rubber stop. Two glass tubes (0 6 mm) pierced the rubber stop, one being as long as to the bottom of the bottle, and the other being 8 mm long. Both glass tubes have 20 mm above the rubber stop at the outside. The longer glass tube connects to a two-way valve via a latex tube, then to the dome top via a hollow T
shaped bolt. The other glass tube connects to drainage latex tube, which directly goes to below the water surface on the other end of the latex tube. In operating, the bottle is inverted and hanged to the top of the floating frame.
The gas inlet and water drainage tubes (o 6 mm) are of latex.
The dome, with narrow necked top and rubber stop, is made of polypropylene.
The open mouth inner diameter of the dome is of 34.2 mm. The dome, with a height of 19 mm, is secured by a hollow T shaped bolt, pierced through rubber stop at the top of the narrow neck, sealed and fixed by a nut. The T shaped bolt connects to the two-way valve, then to the gas inlet latex tube.
The two-way valve is of nylon with connections (0 6 mm) on both sides.
To put the device in operation, follow the steps below:
1. Connect the T shaped bolt with the two-way valve first, then hang the dome to the floating frame.
