Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas filtration, in particular to a condensable gas filtration assembly and method thereof. BACKGROUND

[0002] Condensable gas, also known as vapor, is relative to permanent gas. For any gas, there is a critical temperature. Above the critical temperature, the gas cannot be liquefied by isothermal compression, which is called permanent gas. Below the critical temperature, the gas can be liquefied by simply increasing the pressure. Condensable gas is in a state of small molecular combination when the temperature is lower than its condensation point. They exist in the air in a gaseous state.

[0003] The simplest and most common method to extract condensable gas is filtration. A filter is usually used to extract condensable gas from the air. This technology is easy to master, but the filter needs to be replaced frequently, and it is difficult to effectively filter. Another method to extract condensable gas is adsorption. A layer of adsorbent outside the filter can easily extract condensable gas from the air. The adsorbent requires little maintenance and can filter condensable gas, but the extraction speed is slightly slower than that of the filter. Finally, condensation can be used to extract condensable gas. The principle of condensation is to extract the condensable gas mixed with air into a closed system, freeze the mixed gas to condense the condensable gas, and collect the condensed liquid condensable gas, while the air mixed therein is discharged.

[0004] EVA glue is a hot melt adhesive widely used in photovoltaic modules, furniture, textiles and packaging fields. EVA glue is a condensable gas. EVA glue is in a gaseous state at high temperatures, in a liquid state at medium temperatures (80-120 degrees Celsius), and in a solid state at room temperature. Air is often mixed with condensable gas in a gaseous state. The condensable gas and the air therein need to be filtered and separated. The condensation filtration method is often used to filter and separate the condensable gas and the air. The mixed gas of high-temperature condensable gas and air is cooled through a condensation device. The temperature of the condensable gas is maintained between the melting point and the vaporization temperature, so that the condensable gas is condensed into a liquid.

[0005] At present, the existing technology usually condenses and filters the mixed gas of condensable gas and air through a condensation pipeline, so that the condensable gas therein is liquefied and condensed into a liquid for collection, and the air therein is discharged. However, the condensation pipeline is usually a straight pipe, so that the mixed gas flows through the condensation pipeline for a short time, which easily affects the liquefaction of the condensable gas, thereby easily causing poor filtration effect.
