Coalescence filter

Abstract

The coalescence filter comprises a barrel, a coalescence filter element, a self-adaptive rotary impeller and a driving part, a partition plate is arranged in the barrel and divides the barrel into an upper cavity and a lower cavity, a vertically-through mounting hole is formed in the partition plate, the coalescence filter element is mounted at the mounting hole, an air outlet communicated with the interior of the upper cavity is formed in the upper end of the barrel, and an air outlet communicated with the interior of the lower cavity is formed in the lower end of the barrel. The lower end of the cylinder is provided with a gas inlet and a sewage draining exit which are communicated with the interior of the lower cavity, the self-adaptive rotating impeller is arranged in the upper cavity, the shaft end of the self-adaptive rotating impeller extends to penetrate out of the cylinder in a sealed mode, the driving end of the driving part is in transmission connection with the shaft end of the self-adaptive rotating impeller, and therefore gas can be efficiently purified.

Description

technical field [0001] The invention relates to the technical field of gas-liquid filtration, in particular to a coalescing filter. Background technique [0002] In the current natural gas transportation technology, pipeline transportation is the best way to realize the long-distance transmission of a large amount of natural gas resources. The compressor station is the heart of the long-distance natural gas pipeline. Its core function is to pressurize the natural gas transported in the pipeline and improve the transmission capacity of the pipeline. Centrifugal compressors are usually used as the core equipment of the compressor unit. [0003] In order to avoid gas leakage in the centrifugal compressor, sealing measures must be taken at the shaft end. Due to the low leakage, low wear and low energy consumption of dry gas seals, most compressor manufacturers currently use this type of seal. During the dry gas sealing operation, a gas film with a thickness of about 3 μm will ...

AI Technical Summary

Problems solved by technology

When the working conditions fluctuate greatly, the liquid inside the filter element cannot be discharged in time, and it is easy to block the pores of the filter material, resulting in a rapid increase in the pressure drop of the filter element, and the secondary entrainment phenomenon is likely to occur downstream, which will cause harm to the normal operation of the compressor unit and other equipment, and may cause significant economic loss
