Background technology
The advanced manufacturing industries such as semiconductor/photovoltaic/optical fiber can be used to such as TMA, the poisonous and harmful chemical liquids such as DEZ, SiCl4
State source, usually using push gas push gas liquid with certain pressure into transmission pipeline network force feed to technique board, and technique
Board allows the usual < of flowed fluctuation amplitude 10% to the usual < 1g/min of flow all very littles of this kind of liquid source.This
Flow is minimum for liquid, and needs continual and steady supply, this just proposes liquid source supplying system very high
Constant pressure and flow requirement, for example be mixed into bubble in liquid, when flowing through board flowmeter, will show big flowed fluctuation, shadow
Ring technological parameter and finished product yield.
In order to eliminate inevitable mixed a small amount of gas during the bottle of replacement source, need liquid into transmission pipeline network
Before, a buffer unit that can effectively remove bubble is first passed through, the TMA centralizedly supply systems of the double source bottle switching designed at present,
During dismounting, purging source bottle, minute quantity gas inevitably is remained in the bottle connecting pipe of the sources pigtail, works as source
After bottle liquid-phase outlet valve is opened, residual gas can mix in a liquid, by pipe network, be slowly transported to technique board, flowed through
When gauge, since gas liquid density is different, big flowed fluctuation will be measured, and can actually influence technological parameter and product
Yield.
To solve the above-mentioned problems, a kind of liquid source buffer unit effectively removing bubble is devised in new technology, and its
In key be surge tank, how to ensure surge tank safety and stability, do not generate secondary pollution to liquid source, and effectively remove
Bubble, is very important.
