Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a helium pressurization, recovery and purification system. Background Technology

[0002] While making full use of helium resources, helium recovery is also extremely important. Currently, many domestic companies release helium directly into the atmosphere after leak detection without recovery, resulting in very high helium consumption. Some companies do attempt to recover helium, but the recovery rate is low, the recovery is incomplete, the system configuration is unprofessional, and unsuitable units are selected, which easily leads to leaks.

[0003] Therefore, how to develop a helium recovery device to recover helium resources that originally needed to be vented, while ensuring that the pressure and purity of the recovered helium still meet market requirements, is one of the current research topics. Utility Model Content

The output end of the pressurization device is connected to the input ends of the sludge discharge device and the filtration and purification device, respectively. The output end of the sludge discharge device is connected to the recovery device through different pipelines. The recovery device and the pressurization device are also connected through a one-way valve, and the recovery device and the filtration and purification device are connected through a dual-pass filter.

[0006] Furthermore, the booster device includes an inlet pressure buffer device and a booster, wherein the inlet pressure buffer device is installed at the inlet of the booster, and the intake section is externally connected to the inlet pressure buffer device.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Combined with appendix Figure 1 To be continued Figure 3 As shown, this embodiment discloses a helium pressurization, recovery, and purification system, comprising a pressurization device 1, a wastewater discharge device 2, a recovery device 3, and a filtration and purification device 4. The input end of the pressurization device 1 is connected to an external air inlet 7, through which gas is introduced. The pressurization device 1 is connected to the wastewater discharge device 2 and the filtration and purification device 4 respectively, and pressurized gas is introduced into them. The wastewater discharge device 2 performs multi-stage gas-liquid separation and filtration on the introduced gas, and then discharges it into the recovery device 3 through corresponding connecting pipes. The recovery device 3 is unidirectionally connected to the pressurization device 1 and connected to the filtration and purification device 4 through a dual-pass filter.

[0019] Specifically, the pressurization device 1 includes an inlet pressure buffer device and a pressurizer. The inlet pressure buffer device is used to buffer and control the gas introduced into the inlet section 7 to prevent the gas from entering too quickly and affecting the function of the equipment. After the inlet pressure buffer device and the pressurizer are installed together, the gas entering is safely pressurized. The pressurizer then introduces the pressurized gas, i.e., high-pressure gas, into the sewage discharge device 2 and the filtration and purification device 4.

[0020] The sewage discharge equipment 2 includes a separation sewage discharge device, an exhaust filter, and a housing exhaust port. Several valves are installed on one side of the separation sewage discharge device and the housing exhaust port to control the entry and exit of pollutants.

[0021] The separation and discharge device includes a multi-stage gas-liquid separator 5, which is connected to the recycling equipment via a discharge port connection pipe. A control valve is installed on the discharge port connection pipe. The multi-stage gas-liquid separator 5 is used to separate the introduced high-pressure gas into liquid components. The separated liquid portion is discharged into the recycling equipment 3, while the gas portion is discharged into the recycling equipment 3 after being filtered by an exhaust filter through the exhaust port of the housing. A check valve is installed on the connection pipe between the exhaust port of the housing and the exhaust filter. The exhaust filter is connected to the recycling interface of the recycling equipment 3, and the exhaust filter is bidirectional, allowing waste to be screened and reintroduced into the recycling equipment 3.

[0022] The filtration and purification equipment 4 is equipped with an oil-gas separator for purifying the filtered gas.

[0023] The dual-pass filter between the filtration and purification device 4 and the recycling device 3 can screen out waste and reintroduce it into the recycling device 3.

[0024] The recovery device 3 is equipped with an oil-water separator and an oil-gas separator, which are used to separate the oil and water from the discharged liquid and the oil and gas from the gas, respectively. A one-way valve 6 is installed on the pipeline connecting the recovery device 3 to the inlet pressure buffer device. After opening the one-way valve 6, the internal gas can be returned to the pressurization device 1 and processed again by the filtration and purification device 4 and the sewage discharge device 2, thereby achieving efficient recovery of helium. The bottom of the recovery device 3 is equipped with a sewage discharge port for final recovery and discharge.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Although the implementation process of this utility model has been described in detail above, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. All modifications and equivalent substitutions made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
