The invention relates to a safe and environment-friendly method for protecting storage tanks to mainly solve the problems that in the prior art, the gas consumption of nitrogen protection is excessively large, cost is high, and sulfur-containing gas and other peculiar smell gas are hard to treat. According to the safe and environment-friendly method for protecting the storage tanks, the gas produced by liquid in the storage tanks enters a compressor (18) through a main gas pipe (19) and an inflation pipe (21), the gas is pressurized by the compressor (18) and stored in a buffering tank (5) to serve as one part of positive-pressure protection gas, when the gas stored in the buffering tank (5) cannot meet the positive-pressure protection of all storage tanks, the nitrogen from a nitrogen inlet pipeline (22) is used for performing supplementation, and when the pressure stored in the buffering tank (5) exceeds the designed pressure, the residual gas is sent to a torch or combustion furnace through a torch or combustion furnace leading pipeline (22), the problems are well solved through the technical scheme, and the method can be used in storage tank protection.

A first channel is formed in the side of a first diffusion plate which is on that side of a gas inlet tube and a recess is formed in the side which is on that side of an electrode plate.

The present invention is directed to a method and apparatus for plating a surface of a semiconductor workpiece (wafer, flat panel, magnetic films, etc.) using a liquid conductor that makes contact with the outer surface of the workpiece. The liquid conductor is stored in a reservoir and pump through an inlet channel to the liquid chamber. The liquid conductor is injected into a liquid chamber such that the liquid conductor makes contact with the outer surface of the workpiece. An inflatable tube is also provided to prevent the liquid conductor from reaching the back face of the workpiece.
