The natural gas first enters the feed cloth cavity, and the gas impinges on the support tube supporting the filter element (avoiding the airflow directly impacting the filter element, causing the filter material to be damaged in advance), the larger solid-liquid particles are initially separated and settled under the action of gravity. 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 sinking venting chamber, the larger liquid beads are separated by gravity sedimentation. In addition, in the sinking and discharging chamber, a separating element is further provided, which can effectively collect the droplets to prevent the entrainment of the outlet droplets, thereby further improving 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 replaced in time. .
Filter replacement conditions:
1. The pressure difference reaches the alarm limit
2. The use period is more than half a year
3. The filter element is damaged (the pressure difference suddenly drops)www.inocofiltration.com
