Description

Technical Field

[0001] The utility model belongs to the technical field of gas collection, and in particular relates to a pressure-controlled gas collection and processing device. Background Art

[0002] Gas collection is a common process in laboratories and industry that collects gases from a container or reactor to a specific location. Gas collection can be used for a variety of purposes, such as analyzing gas composition, preparing chemicals, and controlling environmental pollution.

[0003] The fundamental principle of gas collection is to exploit the physical properties of gases, such as their compressibility and diffusivity. When a gas is generated or released, it occupies a certain volume and diffuses into the surrounding space. By controlling the flow and collection method of the gas, the gas can be collected from a reactor or container to a specific location.

[0004] However, during the gas collection process, the gas is sucked into the interior of the gas collection and processing device by squeezing. When the internal gas chamber is full, the gas collection and processing device can only be replaced as a whole, and the internal gas chamber cannot be replaced separately. Utility Model Content
