Blind plate

Author:


The quick-opening blind plate must be fully maintained by professionals, including checking whether there is mechanical damage on the surface of the sealing ring, whether there is rust and dirt in the sealing groove, etc., and checking whether the contact surface of the door and the lock ring is clean. If there is no rust, check whether the screw of the pressure relief bolt hole is in good condition and there is no rust. Through the drain hole at the bottom of the quick-opening blind plate, use a pump-suction detector to detect, the probe extends into the drain, and the pointer remains stable for more than 3 minutes after the hole to read. Check whether the lock belt and sealing belt are in good condition, there should be no obvious scratches and wear, and remove the dirt on the groove, lock belt and sealing belt. Apply a thin layer of anti-corrosion silicone grease to the grooves and sealing surfaces; adjust the door with the omnidirectional handle so that the door enters the neck of the quick-opening blind plate vertically. With the handle resting on the drive connection, turn clockwise until the straps reach the neck entry. Install the door locking block, tighten the pressure alarm bolt, and complete the closing operation. The natural gas purified by the quick-opening blind plate enters the cyclone separation area of ​​the equipment through the inlet of the equipment. When the impurity-containing gas enters the cyclone separation tube in the axial direction, the airflow is strongly rotated by the guiding action of the guide vanes, and the airflow is spiral along the cylinder body. Under the action of centrifugal force, droplets and dust particles with high density are thrown to the wall of the cyclone, and under the action of gravity, they fall along the wall of the cyclone and flow out of the dust discharge port of the cyclone tube to the liquid storage area at the bottom of the equipment. out of the liquid outlet. The rotating airflow shrinks in the cylinder and flows toward the center, forming a secondary vortex upwards and flows through the air duct to the purified natural gas chamber, and then flows out through the top outlet of the equipment. The cyclone separator adopts a vertical cylindrical structure, and the interior is divided into a liquid collection area, a cyclone separation area, and a clean room area along the axial direction. The cyclone sub-components are installed inside, which are evenly arranged in the circumferential direction and are also fixed by the upper and lower tube sheets; the equipment is supported by a skirt, and the head adopts a high-pressure elliptical head. For moisture, we often use the lower air intake scheme, because the lower air intake can use the lower space of the equipment to pre-separate droplets with a diameter greater than 300 μm or 500 μm to reduce the load of the cyclone part.
