Definitions
- the present invention relates to a system for liquid distribution. It applies in particular to the distribution of ultra-pure chemicals, in particular for the microelectronics industry.
- the pumped distribution generates bound particles to variations in pump pressure, and the pumps pose reliability issues.
- tanks are at least 200 l. This leads to dimensions large cabinets, and the tanks must be able withstand the distribution pressure, of the order of 4 bars, or the vacuum.
- the materials used include an inner shell in polyethylene (PE) plastic, perfluoroalkoxy (PFA) or polyvinylidene fluororide (PVDF), and an external reinforcement in fiberglass or stainless steel.
- PE polyethylene
- PFA perfluoroalkoxy
- PVDF polyvinylidene fluororide
- This design of the tanks can cause ionic contamination if the manufacturing is not perfectly under control, and security issues related to pressurization or vacuum for large volumes tanks.
- the object of the invention is to provide a system for space-saving distribution, relatively easy to manufacture, minimizing the risk of contamination of the liquid and optimizing safety.
- the invention also relates to the use of such a distribution system for the distribution of a ultra-pure liquid, in particular hydrogen peroxide, ammonia or hydrofluoric acid.
- the distribution system shown in Figure 1 is intended to supply an ultra-pure liquid to a network user 100.
- the system consists of an upstream part supply 1 and a downstream distribution part 2.
- a sampling can 10 used to carry out analyzes of the conveyed liquid.
- Line 14 is equipped with two filters 15A, 15B mounted in parallel, then a sampling container and 16, and it ends up at the user network 100.
- Line 17 stuck on line 14 downstream filters 15A, 15B allows the recycling of liquid to the inlet of the tank 11, and another pipe 18 makes it possible to recycle excess liquid from user network 100 to the same location.
- the installation also includes a number of known measurement and control devices per se and which have not been 'represented for the sake of clarity drawing.
- the barrels 3A and 3B can have a volume of 100 to 20,000 liters, the tank 11, made of PE, PFA or PVDF slightly reinforced with fibers, a volume of 200 l to 5 m 3 , and the containers 12A and 12B have a much lower volume than the previous one, typically from 1 to 50 liters.
- the filter 7 is a microfiltration member with membrane up to 0.2 ⁇ m
- filter 8 provides filtration up to 0.1 ⁇ m
- filters 15A and 15B filtration up to 0.05 ⁇ m.
- each container 12A, 12B consists of a section of tube 23 made of PE, PFA or PVDF unreinforced, the thickness of which is adapted to withstand distribution pressure.
- This tube is arranged vertically, its upper end is closed by a plug 24 connected to the associated nitrogen source 21A or 21B, and its lower end is closed by a second plug 25 to which is connected a connecting tee 26.
- the two horizontal branches of this tee are connected respectively, upstream to a pipe 27 itself connected to the tube plunger 13, and downstream to a pipe 28 itself connected to line 14.
- the size of the distribution part 2 is particularly reduced.
- the gaseous sky of barrels 3A and 3B is maintained at slight overpressure, at a pressure less than 100 mbar by the device 4.
- the pumped liquid by the pump 5 passes through the filters 7 and 8, and part of the liquid is eventually recycled via line 9.
- the non-recycled liquid reaches the storage tank 11, via a second dip tube 29 which supplies it at source.
- the gaseous sky of this tank is constantly maintained at a predetermined pressure P2, less than 500 mbar by source 20.
- One of the two containers 12A, 12B is maintained at a positive pressure P4 or zero but less than pressure P2, by its source nitrogen 21B, and its outlet valve is closed while its inlet valve is open.
- the other container 12A has its valve inlet valve closed, its outlet valve open, and it is maintained at a pressure P3 greater than P2 and equal to the distribution pressure by its nitrogen source 21A.
- the container 12B is filled while the container 12A is used for distribution.
- the pressures of the two containers are reversed, as well as the state of their inlet valves and outlet, so that container 12A fills while that the container 12B empties into the line of distribution 14.
- the liquid thus distributed continuously undergoes the last filtration step in 15A and / or 15B, then is sent via line 14 to user network 100.
- Ultrapure liquid can optionally be recycled in the tank 11, from the line 14 via the branch 17 and / or from network 100 via line 18.
- a third dispensing container similar to containers 12A, 12B and mounted in parallel with them, as a container for help.
