Description

Technical Field

[0001] This utility model relates to the field of energy-saving technology for Dewar bottle emissions, and in particular to an energy-saving device for Dewar bottle emissions. Background Technology

[0002] The existing terminal storage equipment for liquefied natural gas, liquid oxygen, liquid nitrogen, and liquid carbon dioxide is Dewar flasks. During use, they are all connected to the vaporizer in the liquid direction and used after being vaporized into gas. This can easily lead to the problem of overpressure safety valves tripping and discharging, causing safety hazards and gas loss.

[0003] Therefore, it is essential to provide a Dewar bottle emission energy-saving device to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this utility model is to provide a Dewar flask emission energy-saving device to overcome the shortcomings of the prior art. This Dewar flask emission energy-saving device is connected to the Dewar flask through a stainless steel buffer tank. It can introduce the gas in the Dewar flask into the stainless steel buffer tank while ensuring safety during the use of the Dewar flask, so that the Dewar flask itself does not emit overpressure, increases the gas space in the Dewar flask, collects the emitted gas, and avoids gas waste. At the same time, the gas in the stainless steel buffer tank can be sent into the gas pipeline when in use.

[0005] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0006] A Dewar bottle emission energy-saving device is provided, including a stainless steel buffer tank. An inlet safety valve and an outlet safety valve are fixedly installed on the stainless steel buffer tank. The inlet safety valve and the outlet safety valve are connected to the stainless steel buffer tank. A buffer check valve is installed at the inlet of the inlet safety valve. A buffer pressure-bearing hose is connected to the inlet end of the buffer check valve. The other end of the buffer pressure-bearing hose is connected to the discharge port of the Dewar bottle.

[0007] An outlet check valve is installed at the outlet of the safety valve, a pressure regulator is installed at the outlet of the check valve, a discharge pressure hose is connected to the outlet of the pressure regulator, and the other end of the discharge pressure hose is connected to the air supply line.

[0008] Specifically, the opening pressure of the imported safety valve is lower than that of the safety valve of the Dewar flask.

[0009] Specifically, the pressure value of the pressure regulator is the same as the pressure of the gas pipeline.

[0010] Specifically, a pressure gauge is installed on the stainless steel buffer tank.

[0011] This invention uses a stainless steel buffer tank to buffer the Dewar flask, allowing the gas inside the Dewar flask to be introduced into the stainless steel buffer tank while ensuring safety during use. This prevents the Dewar flask from over-pressurizing and increases the gas space within the Dewar flask, allowing for the collection of exhaust gas and avoiding gas waste. At the same time, the gas in the stainless steel buffer tank can be sent into the gas pipeline during use. Attached Figure Description

[0024] The present invention will be further described in conjunction with the following embodiments.

[0025] Example 1:

[0026] like Figure 1 As shown, a Dewar bottle emission energy-saving device includes a stainless steel buffer tank 1. An inlet safety valve 2 and an outlet safety valve 3 are fixedly installed on the stainless steel buffer tank 1. The inlet safety valve 2 and the outlet safety valve 3 are connected to the stainless steel buffer tank 1. A buffer check valve 4 is installed at the inlet of the inlet safety valve 2. A buffer pressure-bearing hose 5 is connected to the inlet end of the buffer check valve 4. The other end of the buffer pressure-bearing hose 5 is connected to the Dewar bottle discharge port.

[0027] The opening pressure of the imported safety valve 2 is less than the opening pressure of the safety valve on the Dewar flask.

[0028] One end of the pressure hose is connected to the outlet of the Dewar bottle, and the other end is connected to the inlet of the buffer check valve 4. It has the function of unidirectional output of gas from the Dewar bottle into the stainless steel buffer tank 1, so as to achieve the effect of not backflowing.

[0029] The outlet of the buffer check valve 4 is connected to the inlet of the inlet safety valve 2, and the outlet of the inlet safety valve 2 is connected to the inlet of the stainless steel buffer tank 1. The starting pressure of this safety valve is slightly lower than the starting pressure of the Dewar flask safety valve. It has the function of allowing gas to enter the buffer tank through the buffer pressure-bearing hose 5 when the pressure of the Dewar flask rises but does not reach the Dewar flask safety start pressure, but reaches the starting pressure of the inlet safety valve 2 of the stainless steel buffer tank 1, thereby increasing the gas flow space and collecting the exhaust gas.

[0030] An outlet check valve 6 is installed at the outlet of the outlet safety valve 3. A pressure regulator 7 is installed at the outlet of the outlet check valve 6. A discharge pressure hose 8 is connected to the outlet of the pressure regulator 7. The other end of the discharge pressure hose 8 is connected to the air supply line.

[0031] The pressure value of the pressure regulator 7 is the same as the pressure of the gas pipeline.

[0032] Pressure gauge 9 is installed on the stainless steel buffer tank 1.

[0033] The outlet of the buffer tank is connected to the inlet of the outlet check valve 6, and the outlet of the outlet check valve 6 is connected to the pressure regulator 7. The pressure regulator 7 adjusts the pressure to be the same as the pressure of the gas pipeline. The outlet of the pressure regulator 7 is discharged through a pressure-bearing hose and connected to the gas pipeline. This allows the gas to be input into the gas pipeline through pressure regulation when the gas pressure in the buffer tank is higher than the pressure of the gas pipeline. The gas in the gas pipeline will not flow back into the stainless steel buffer tank 1, thus achieving the effect of collecting the exhaust gas from the Dewar flask for use in production.

[0034] This utility model uses a stainless steel buffer tank 1 to buffer the Dewar flask, which can introduce the gas inside the Dewar flask into the stainless steel buffer tank 1 while ensuring safety during the use of the Dewar flask. This prevents the Dewar flask from over-pressurizing and increases the gas space inside the Dewar flask, allowing for the collection of the discharged gas and avoiding gas waste. At the same time, the gas in the stainless steel buffer tank 1 can be sent into the gas pipeline when in use.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
