Hose, and then flow into container, after analysis detection is finished, the service valve of water seal lower end is opened, can will be given up by overhauling pipe
Liquid complete liquidation is clean.
However its discharge organic solvent be the left end fallen in U-shaped water seal, be swim in U-shaped water seal left end water it is upper
Face, and water seal outlet is the right end for being connected to U-shaped water seal；Certainly, a small amount of organic solvent is had in the effect of drippage gravity
Lower transfer swims in the waterborne of U-shaped water seal right end, and when waste liquid is more than water seal height, the organic liquid waste of U-shaped water seal right end can lead to
Cross water seal outlet and flow to waste liquid outlet hose, but the organic liquid waste of the U-shaped water seal left end of volume still remains in pipe, can not and
When be discharged, can not completely effectively solve the problems, such as.
Meanwhile when doing other materials analysis using the device, when the waste liquid specific gravity of discharge is greater than water, waste liquid can be accumulated
In the bottom of U-shaped water seal, extra water can flow to waste liquid outlet hose from water seal outlet；At this point, if being discharged when thinking of useless
Liquid then needs to open service valve, and after opening the outflow of service valve solution, the water in U-shaped water seal can be reduced, it will affect water seal effect,
There are security risks；If being discharged not in time, and can there are the problems such as blocking, a kind of original disclosed in notification number CN206311506U
The waste liquid discharge device applicability and practicability of sub- absorption spectrophotometer be not strong.
