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 wauming. 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 -NO}) 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.

Summary of Invention
In one aspect of the present invention, there is provided a device for
trapping ebullition from
water, said device comprising: a) a floating frame, b) an inverted storage
bottle suspended from a
top portion of the floating frame, the inverted storage bottle comprises an
inlet tube and an outlet
drainage tube, the outlet drainage tube connected to a first tubing for
submersion of the first
tubing below the water; and c) a dome having an outlet dome tube installed on
a top surface of
said dome, the dome suspended from a top portion of the floating frame;
wherein the inlet tube
of the inverted storage bottle is connected via a second tubing to a first end
of a two-way valve;
and a second end of the two-way valve is attached to the outlet dome tube.

Brief Description of Drawings

Figure 1 illustrates an embodiment of the present invention.
Detailed Description

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.

An embodiment of the device for sampling ebullition is provided in Figure 1,
and
described as follows. An outlet dome tube 8, installed on the top of a dome 5,
is connected to the
inlet end of a two-way valve 6. The outlet end of the two-way valve 6 is
connected to the inlet
end of an intake latex tube 3. The outlet end of the inlet latex tube 3 is
connected to the intake
tube 9 of an inverted storage bottle 2 that is attached by string 15, to a
ring 16 on the top of an
arc frame 1. The outlet tube 10 of the inverted storage bottle 2 is connected
to one end of a
drainage latex tube 4, and other end of the drainage latex tube 4 is situated
within water 14. The
dome 5 hangs attached to the arc frame 1, via threads 12 which connect between
rings 11 (on the
arc frame 1) and dome rings 7 (on the dome 5). The arc frame 1 is situated on
floating balls 13 at
each corner of a square frame 17.

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 natro* neck sealed by rubber
stop. Two glass
tubes (r 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 (0 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.
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.
Cares should be taken not to trap any air bubbles in dome, tubes and bottle
when connecting at
the start.
The advantages of this invention:
1. The dome and storage bottle are connected via tubes so that it eliminated
to possible
errors in floating box method duo automatic process.
2. It eliminates manual sampling operation steps. When sampling is needed,
just change
the storage bottle, and send it to a lab for component analysis.
3. It does not need a carriage gas, electricity, and does not have limitations
on gas type
and its concentration background (in the air).
4. This device is simple, low cost, small in size, and makes sampling accurate
and precise,
and resolves the problems of effectively collecting ebullition from waters,

Methods of Realization and Its Method
The floating frame is made of two galvanized iron thread, banded in a bow
shape, 90 degree
cross welding together. The frame height is 400 mm with a square shape bottom,

diameter.
The storage bottle is of polypropylene with a narrow neck sealed by rubber
stop. Two glass
tubes (o 6 mm) pierced the rubber stop, one being as long as to the bottom of
the bottle, and the
other being 8 mm tong. 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 (0 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
nun, 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 (o 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.
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.
