2) in the case where not interfering fermentor to run, fermentation gas can be measured in real time and can show and count in data
It calculates and reads yield in module；
3) gas, which not only measures volume conveniently, can also meet what real time sample detected fermentation gas product, can be same
When take into account the monitoring of fermentation gas yield and the analysis of property.
Detailed description of the invention
Fig. 1 is that the utility model fermentation gas is collected and measuring device structural schematic diagram；
Specific embodiment
Further explanation is made to the utility model with reference to the accompanying drawing.
A kind of experiment fermentation gas collection and measuring device, as shown in Figure 1, including fermentor 1, collection airbag 2, air-tight bottle
Device 3, measuring device 4 and waste collecting device 6, fermentor 1, collection airbag 2, sealing bottle 3 and waste collecting device 6 pass through
Gas-guide tube is sequentially connected, and the air guide tube opening sealed in bottle 3 is located at liquid level or more, water outlet be located at liquid level hereinafter, and
Waste collecting device 6 is connected by water outlet, measuring device 4 is located at sealing 3 lower part of bottle, for incuding and measuring air-tight bottle
The weight of device.
Measuring device 4 is made of electronic scale, computing module and display device three parts, and electronic scale measures sealing bottle
The weight of the water of middle loss is shown via preset specific calculation procedure in measuring by the data of electronic scale real-time Transmission
Fermentation gas volume.
The device further includes cushion block 5, for placing sealing bottle 3 and measuring device 4.
Fermentor 1 holds fermentation substrate and fermentation liquid, seals in bottle 3 and holds water.
The gas outlet of fermentor 1 is equipped with valve.
The air inlet for collecting airbag 2 is equipped with injection valve, and gas outlet is equipped with export valve.
The sealing bottle 3 is seal glass water bottle, and air inlet is equipped with air guide valve, and liquid outlet is equipped with water outlet valve
Door.
The lower part water outlet of the sealing bottle 3 is on the water filling port of waste collecting device 6.
The method for carrying out fermentation gas collection and measurement using the device is as follows:
Step 1: sealing bottle 3 and measuring device 4 being individually positioned on cushion block 5, so that the lower part of sealing bottle 3
Water outlet is on the water filling port of waste collecting device 6.
Step 2: injecting enough water into sealing bottle 3, make liquid level in the water filling port on water bottle top and going out for lower part
Between the mouth of a river, the water filling port, outlet valve and air guide valve of water bottle are closed；
Step 3: after water filling, measuring device 4 being returned to zero；
