Embodiment Construction

[0007] Accompanying drawing is the specific embodiment of the present invention;

[0008] The content and working principle of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] Referring to the accompanying drawings, the present invention includes a gas collecting bottle 2 communicated with the biogas pipe 1, a buoy 3 is installed in the gas collecting bottle 2, and the buoy 3 communicates with the water in the gas collecting bottle 2 through the water conduit 4, and the bottom of the buoy 3 The water outlet pipe 5 is connected, and the water outlet pipe 5 is connected from the lower part of the gas collection bottle 2 to the outside of the gas collection bottle 2 to form a constant pressure biogas measuring device. After the work starts, as the biogas produced by the anaerobic digestion bottle enters the gas collecting bottle 2 from the biogas pipe 1, the water level in the gas collecting bottle 2 drops, an...

Abstract

The invention belongs to environmental engineering area. The measuring apparatus includes gas-collecting vessel. A biogas tube is connected to the gas-collecting vessel. A buoy is installed inside the gas-collecting vessel, and an aqueduct is connected inside the buoy. Outlet pipe in lower part of the buoy is connected to an outlet pipe outside the vessel. Then, the outlet pipe outside the vessel is connected to a measuring tank. Yield of biogas is measured indirectly from measuring water discharge. Comparing with drainage and gas collection method, the disclosed method keeps pressure stable in examination so as to raise measuring accuracy.

Description

technical field [0001] The invention relates to a biogas measuring device, in particular to a constant-pressure biogas measuring device for anaerobic digestion test. Background technique [0002] In wastewater anaerobic digestion or anaerobic biological treatment, biogas production is an important indicator reflecting the anaerobic digestion process. There are many methods for measuring biogas production, among which drainage gas collection method is the most used one. The drainage gas collection method is to connect the biogas pipe of the anaerobic digestion bottle (that is, the anaerobic digestion reactor) to a bottle filled with water and the mouth is sealed (called a gas collection bottle), and then lead out a gas pipe from the gas collection bottle. Outlet pipe, during the anaerobic digestion experiment, the biogas produced by the digestion bottle enters the gas collecting bottle, and the water in the gas collecting bottle is pressed out through the outlet pipe, and th...
