The QYWL series vapor-liquid mesh filter element is made of precision stainless steel wire mesh with multiple layers of weaving, which has significant characteristics such as efficient gas-liquid separation, low pressure drop, and large pollutant absorption capacity. The multi-layer metal mesh structure can effectively capture liquid droplets and mist carried in the gas, with a separation efficiency of over 99%. Widely applicable to gas-liquid separation conditions in the fields of petrochemicals, environmental engineering, mechanical manufacturing, etc., it has excellent temperature and corrosion resistance, supports repeated cleaning and regeneration, has a long service life, and can also be customized according to non-standard requirements.
The QYWL series vapor-liquid mesh filter element is a high-performance filter element specially designed for industrial gas-liquid separation conditions. It adopts a precision wire mesh structure improved by the traditional knitting rod needle weaving method, which can efficiently capture liquid droplets and mist carried in the gas and achieve precise gas-liquid separation. This series of filter cartridges has significant characteristics such as low resistance, large pollutant holding capacity, repeatable cleaning, and durability. It is widely suitable for multiple industrial fields such as petrochemicals, environmental engineering, and mechanical manufacturing. It is an indispensable core filter element in gas-liquid separation devices, providing solid guarantees for stable and efficient operation of industrial production.

The QYWL series vapor-liquid mesh filter element is made of stainless steel wire, alloy wire or non-metal wire with a diameter of 0.08~0.55 mm, and is woven using single strand, multi strand or metal fiber composite weaving technology. The mesh surface can be processed into a flat or corrugated type, with opening sizes ranging from 2 × 3mm to 12 × 6mm, and width specifications extending from 40mm to 1400mm, fully meeting the fine requirements of different working conditions. The materials include 304, 316L, 321, 904L stainless steel and nickel based alloys, with a temperature resistance range of -20 ℃ to 250 ℃, a working pressure of 0.1~2.5MPa, and outstanding resistance to acid and alkali corrosion. According to the HG/T21618-1998 standard, we offer four standard models: SP, DP, HR, and HP. We also support non-standard customization and can flexibly adjust the wire diameter, mesh size, and number of layers according to customer needs.
The QYWL series vapor-liquid mesh filter element is widely used in distillation tower gas-liquid separation, catalytic cracking unit inlet purification in petroleum refining, evaporation absorption tower mist capture in the chemical industry, flue gas desulfurization and dust removal, industrial waste gas purification in the environmental protection field, as well as oil and gas separation in mechanical equipment, compressor inlet filtration, automotive engine air filtration, ship oil-water separation and other scenarios. In addition, it can also be used for electromagnetic interference shielding of electronic and electrical products, covering multiple industrial sectors such as energy, chemical, environmental protection, machinery, automotive, electronics, etc.
The QYWL series vapor-liquid mesh filter element adopts a multi-layer precision wire mesh structure, with a separation efficiency of over 99% for particles larger than 3 μ m. The pressure drop when gas passes through is only 250-500Pa, which has almost no effect on the operation of the system. Wide temperature resistance range, high pressure resistance level, excellent material resistance to acid and alkali, high temperature resistance, long service life, and low maintenance cost. Supporting non-standard customization, it can flexibly match wire diameter, mesh size, and number of layers according to actual working conditions, with strong adaptability and better comprehensive performance than general products. The system stability is significantly improved.
Leakage problems are often caused by aging seals or improper installation of filter elements. Regular inspections and replacement of O-rings are necessary, and installation must strictly follow the specified torque. The decrease in filtration efficiency is usually caused by clogging of the filter element. It is recommended to install a pre filtration device and regularly monitor the pressure difference. If the pressure difference exceeds the standard, it should be cleaned or replaced in a timely manner. Excessive pressure fluctuations may cause the filter element to rupture, and safety valves and pulsation dampers should be installed to eliminate the impact of water hammer effect. Thoroughly exhaust during installation to avoid affecting the filtration effect due to air resistance.
