Description

Technical Field

[0001] The utility model relates to the technical field of oil removal filters, in particular to a portable oil removal filter applied to process gas pipelines. Background Art

[0002] Process gas refers to various gases used in the industrial production process, which usually belong to flammable and explosive gases or toxic gases. They play an important role in many production links, such as semiconductor manufacturing, chemical industry, pharmaceutical industry, food processing, etc. These gases may directly participate in chemical reactions or be used as protective gases, carrier gases, etc. The quality of process gas directly affects the quality, output and production safety of products.

[0003] Oil removal filtration is particularly important in the treatment of process gas because the presence of oil mist and oil droplets will affect the purity of the gas and the efficiency of subsequent processes, and it is also easy to cause the accumulation of oil droplets at the lower part of the pipeline, affecting the gas transportation. For example, in the semiconductor manufacturing process, high-purity gas is one of the key factors to ensure the quality of chips. Oil droplets will not only contaminate the inside of the reactor, but may also lead to uncontrollable chemical reactions, thus affecting the electrical performance and reliability of products.

[0004] At present, some oil removal filters applied to process gas on the market are modified from oil removal filters on compressed air pipelines. The current oil removal filters are usually connected to external inlet and exhaust pipelines through threads. The reliability of thread connection is poor and leakage is likely to occur. Moreover, the filter body is usually made of cast aluminum parts in the current industry, and the corrosion resistance effect is poor, which is not suitable for process gas with relatively complex working conditions. Therefore, we propose a portable oil removal filter applied to process gas pipelines to solve this problem. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a portable oil removal filter applied to process gas pipelines to solve the problems raised in the above background art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A portable oil removal filter applied to process gas pipelines includes: an oil removal filter base, a filter element and a connector. An air inlet is opened at the bottom of the oil removal filter base, and an air outlet is opened at one side of the oil removal filter base. An air inlet flange is integrally formed at the bottom of the oil removal filter base, and an air outlet flange is integrally formed at one side of the oil removal filter base;

[0008] The connecting piece includes an oil separator filter rod and an oil removal filter connector. The oil removal filter connector is threadedly connected to the top of the oil removal filter base, and the oil removal filter connector is fixedly sleeved on the outside of the oil separator filter rod;

[0009] The filter element of the filter includes a filter element support seat, a filter medium, and a filter element housing. The filter element support seat is threadedly sleeved on the outside of the oil removal filter connector. The filter medium is fixedly installed on the top of the filter element support seat. The filter element housing is fixedly sleeved on the outside of the filter element support seat. The oil removal filter connector, the oil separator filter rod, the filter element housing, and the filter element support seat are all made of stainless steel, and the oil removal filter base is made of cast stainless steel.

[0010] Preferably, a communication hole is provided on the inner wall of the top of the air inlet, and a guiding hole is provided on the top of the filter element support seat for docking with the communication hole.

[0011] Preferably, a return gap is provided between the inner wall of the oil removal filter connector and the outer surface of the oil separator filter rod.
