How natural gas filters work
The natural gas first enters the feed air cavity, and the gas first hits the support tube supporting the filter element (avoiding the airflow directly impacting the filter element, causing the filter material to be damaged in advance), and the larger solid-liquid particles are initially separated and under the action of gravity Settle to the bottom of the container (slave regularly from the drain). Then, the gas is filtered from the outside to the coalescing filter element, and the solid particles are trapped by the filter medium, and the liquid particles gradually aggregate and grow on the inner surface of the filter element due to the coalescence function of the filter medium. When the droplet reaches a certain size, it will fall off from the inner surface due to the impact of the airflow and enter the inner flow passage of the filter element and then enter the sinking and discharging chamber. In the effluent chamber, the larger liquid beads are separated by gravity sedimentation. In addition, there is a separation element at the sinking and discharging chamber, which can effectively collect the droplets to prevent the entrainment of the outlet droplets. Further improve the separation effect. The last clean gas flows out of the filter separator. As the gas throughput increases, the particles deposited on the filter element will cause an increase in the pressure difference of the gas filter. When the pressure difference rises to a specified value (read from the differential pressure gauge), the filter element has been severely blocked and should be timely. replace. The initial pressure difference of the filter separator is not higher than 20KPa, and the replacement pressure difference is not higher than 100KPa.
