The invention discloses a continuous observing
system of dissolving
nitrous oxide in a
water body in a
surface layer, and relates to monitoring equipment of
greenhouse gases. The
system is provided with a surface-layer water pump, filter equipment, temperature and
salinity measurement equipment, a flow controller, a
water vapor balancer, a temperature probe, a cold well, a gas pump, a waterproof
electrode, an output spectrum
detector of an off-axis integral chamber and a standard
gas cylinder, wherein a water inlet of the surface-layer water pump is installed in water, a water outlet of the surface-layer water pump is connected with an inlet of the filter equipment, the outlet of the filter equipment is connected with the temperature and
salinity measurement equipment, the outlet of the temperature and
salinity measurement equipment is connected with the inlet of the flow controller, the outlet of the flow controller is connected with the
water vapor balancer, an air outlet arranged at the upper part of the
water vapor balancer is connected with the inlet of the cold well, the temperature probe is arranged in the water vapor balancer, the outlet of the cold well is connected with the inlet of the gas pump, the outlet of the gas pump is connected with the waterproof
electrode, the outlet of the waterproof
electrode is connected with the inlet of the
detector and the outlet of the standard
gas cylinder, the output end of the
detector is connected with an auxiliary balancer which is arranged at the bottom in the water vapor balancer, and a
wastewater outlet is formed at the bottom of the water vapor balancer.
