29-Function and role of disc-type vane-separated internals in horizontal natural gas filtration and separation units and horizontal coalescing separation units

Each is composed of two horizontal cylinder structures. The main cylinder serves as the core separation area, while the secondary cylinder functions as the collection and storage area for the liquid-solid mixed phase. The incoming airflow enters radially from the upper side of the main cylinder, while the purified airflow exits axially from the rear part of the main cylinder; the liquid-solid mixture is discharged separately into the front and rear chambers. As shown in the figure below:

Regarding the internal structure of horizontal gas filtration separators and horizontal coalescing separators, it can be briefly explained using the horizontal super filtration separator shown in the figure below as an example. The upper cylinder is the main cylinder with core separation functionality, while the lower cylinder is the auxiliary cylinder with storage functionality. The front compartment of the main cylinder is a first-stage filter element-type separation chamber, which performs primary separation of the airflow and the substances it carries through the tiny pores in the filter elements. The separated substances are then discharged via the discharge pipe in the front compartment to the storage area of the front compartment of the secondary cylinder, where they are stored and later removed. The rear chamber of the main cylinder is a two-stage disc-type vane separation chamber; it uses vane separation elements to aerodynamically separate the liquid droplets and mist that have passed through the filter elements in the first stage and have undergone pre-coagulation/coagulation, but which have not settled due to gravity in time and thus remain suspended in the airflow. This second-stage vane separation ensures that the product gas exiting axially from the rear of the separator contains only trace amounts of liquid mist, meeting the technical requirements ； The separated and removed carrier material is discharged through the rear discharge pipe into the storage area at the rear of the auxiliary cylinder, where it is stored and later released.

It is important to emphasize the differences between horizontal filtration separators and horizontal coalescing separators: 1. Different applications: Horizontal filtration separators are generally used for the thorough purification of liquid-containing gas streams that contain a large amount of solid particles. Horizontal coalescing separators are generally used for the deep purification of liquid-foam-containing gas streams with very low amounts of solid particles entrained. The standard type is used to meet the technical requirements for removing particles larger than 5 microns from the exhaust stream of the separator, while the premium type meets the stringent technical requirements of removing particles larger than 0.1–5 microns from the separator’s exhaust stream, depending on the circumstances. 2. Different airflow directions: Horizontal filter separators are primarily used for filtering out solid particles. To accommodate these particles and extend the lifespan of the filter elements, it is necessary for the feed airflow to flow from the outer surface toward the inner surface; the outer surface of the filter elements has a larger diameter and thus a greater surface area. Horizontal coalescing separators are primarily used to remove tiny liquid droplets from air streams that contain almost no solid particles. The coalescing process requires the air flow to slow down continuously as it passes through the filter elements, so that the larger droplets formed through coalescence can more effectively detach from the surface of the filter elements without being broken up again by the fast-moving air and dispersed back into the cleaned air stream. Therefore, the incoming air flow must move from the inner surface side toward the outer surface side; since the outer surface of the filter elements has a larger diameter and greater surface area, the air flow slows down as it moves radially through the filter elements, which facilitates efficient coalescing and removal of droplets from the air flow. 3. The inlet pipes for the raw gas are installed at different positions on the upper side of the main cylinder, in order to meet the technical requirements regarding different airflow directions for the horizontal filter separator and the horizontal coalescer separator. 4. Different costs: The cost of the internal components of the filtration filter element is relatively low, as the requirements regarding its structure and materials are simple ； The cost of the internal components for coalescing filters is significantly higher, with complex structural and material requirements.
