Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a germanium tetrachloride storage tank comprises a tank body 1, a liquid pipe 2 and a gas pipe 3, wherein a flange plate 4 is arranged at a bottleneck of the tank body 1, the liquid pipe 2 and the gas pipe 3 are respectively connected with the flange plate 4 in an air-tight manner and communicated with the inside of the tank body 1, the tail end of the liquid pipe 2 is located at the bottom of the tank body 1, and the tail end of the gas pipe 3 is located at the top of the tank body 1. The storage tank is a basic structure of the existing germanium tetrachloride storage tank, when materials are taken, an air pipe 3 and a liquid pipe 2 of the storage tank are connected with a PFA pipeline, then high-purity nitrogen is introduced into the air pipe 3, germanium tetrachloride in the storage tank is taken out from the liquid pipe 2 under the action of air pressure, however, when high-purity nitrogen is introduced into the storage tank, the germanium tetrachloride and components in the air are reacted because the air is not emptied, and the quality of products is reduced.

For this purpose, a three-way valve 5 is added to the liquid pipe 2 and the gas pipe 3, respectively, and a connecting pipe 7 is arranged between the two three-way valves 5, and a two-way valve 6 is arranged on the connecting pipe 7, and the two-way valve 6 is fixed on the flange 4. Before the material taking operation is carried out, the two-way valve 6 is adjusted to enable the connecting pipe 7 between the two three-way valves 5 to be in a communicating state, the two three-way valves 5 are adjusted to enable the two three-way valves to be respectively communicated with the connecting pipe 7 on the two-way valve 6, the liquid pipe 2, the air pipe 3 and the connecting pipe 7 on the flange plate 4 are in a communicating state and cannot be communicated with the pipeline inside the tank body 1, and then high-purity nitrogen is introduced into the air pipe 3 to blow and sweep the PFA pipeline and the air inside the air pipe 3. After purging is finished, the two-way valve 6 is closed, the two three-way valves 5 are adjusted to enable the liquid pipe 2 and the gas pipe 3 to be respectively communicated with the interior of the tank body 1, at the moment, the germanium tetrachloride stored in the tank body 1 is continuously taken out through high-purity nitrogen, and the gas in the gas pipe 3 and the PFA pipeline is discharged through purging, so that the pollution of the germanium tetrachloride is reduced, and the purity of the germanium tetrachloride is guaranteed.

After the material taking is finished, the two-way valve 6 is opened again, the three-way valve 5 is adjusted to enable the liquid pipe 2 and the gas pipe 3 to be respectively communicated with the two-way valve 6 and the connecting pipe 7 thereof, and high-purity nitrogen is introduced into the gas pipe 3 to sweep and recycle the PFA pipeline and the residual germanium tetrachloride in the liquid pipe 2, so that the leakage and the environmental pollution are avoided.

The top of the tank body 1 is further provided with a right-angle support 8 (the structure is shown in fig. 2), the bottom of the right-angle support 8 is fixed on the flange plate 4, the side surface of the right-angle support is provided with two mounting holes 9, and the two three-way valves 5 are respectively fixed on the two mounting holes 9. The purpose is to prevent that the pipeline from buckling and damaging in order to reduce the stress that produces liquid pipe 2 and trachea 3 when operating three-way valve 5 to avoid germanium tetrachloride to leak the polluted environment.

The flange plate 4 is fixed at the bottle mouth of the tank body 1 through a bolt 10, and a sealing gasket 11 is arranged between the flange plate 4 and the tank body 1, so that the inside of the tank body 1 is conveniently cleaned, and meanwhile, the sealing performance is also ensured. The liquid pipe 2 and the gas pipe 3 are both corrosion-resistant stainless steel pipes, so that the service cycle of the storage tank can be prolonged.
