The invention discloses a continuous
observation system for dissolving of
methane in a
surface water body, relating to
greenhouse gas monitoring equipment. The continuous
observation system is provided with a
surface water pump, filtering equipment, temperature and
salinity measurement equipment, a flow controller, a water-vapor balance device, a temperature probe, a gas pump, a
cold trap, a waterproof
electrode, a filtering device, an off-axis integral cavity output spectrum
detector, a valve and a standard
gas cylinder; a water inlet of the
surface water pump is arranged
underwater, a water outlet of the surface water pump is connected with an inlet of the filtering equipment, an outlet of the filtering equipment is connected with the temperature and
salinity measurement equipment, an outlet of the temperature and
salinity measurement equipment is connected with an inlet of the flow controller, an outlet of the flow controller is connected with the balance device which is communicated with the
atmosphere, an air outlet formed in the upper part of the balance device is connected with a gas inlet of the gas pump, the temperature probe is arranged in the balance device, a gas outlet of the gas pump is connected with an inlet of the
cold trap, an outlet of the
cold trap is connected with the waterproof
electrode, an outlet of the waterproof
electrode is connected with an inlet of the filtering device, an outlet of the filtering device is connected with an inlet of the
detector, and an outlet of the standard
gas cylinder is connected with the balance device and the
detector through the valve respectively.
