Description

Technical Field

[0001] The invention relates to the technical field of partition-free filters, in particular to a partition-free filter and a filtering method. Background Art

[0002] Nowadays, gas turbines have become an important part of the power supply system. At the same time, they play an important role in the development and transportation of natural gas and crude oil, and in large-scale industrial fields. Clean air is crucial to the operating efficiency and reliability of gas turbines. Dust and pollutants in the air are the natural enemies of high-speed gas turbines and turbines. Dust and pollutants can cause wear, corrosion and scaling of the blades inside the equipment. Wear and corrosion can shorten the service life of the equipment blades, and scaling can reduce the operating efficiency and output of the entire equipment, and in severe cases can cause surge failures.

[0003] The existing air filter filters dust and other impurities in the air through a filter net, such as "the invention patent application with publication number CN115569449A discloses an air filter", and filters the air by setting a filter element. However, when the filter net filters the air, impurities in the filter will accumulate on the filter net and gradually reduce the efficiency of filtering the air. A disassembly device is provided for easy disassembly, but it is troublesome to frequently disassemble and replace the filter element. Furthermore, "the invention patent application with publication number CN113877325A discloses an air filter" records that dust is removed by a cleaning brush when the filter element is working, but this dust removal method does not remove dust cleanly enough and continuous dust removal is likely to damage the filter element.

7. A filter without partition according to claim 1, characterized in that: The regulating device (4) comprises a sliding inclined block (401), a limiting screw rod (402) and a third motor (403); the third motor (403) is fixedly connected to the inner surface of the housing (1); the limiting screw rod (402) is fixedly connected to the output end of the third motor (403); the limiting screw rod (402) is rotatably connected to the inner surface of the housing (1); the limiting screw rod (402) is threadedly connected to the inner surface of the sliding inclined block (401); and the sliding inclined block (401) is slidably connected to the inner surface of the housing (1).

8. A filtering method according to any one of claims 1 to 7, characterized in that: The following steps are involved: Step 1: air enters the air inlet from the opening below the rain cover (2) and is initially filtered through the folding device (5) to filter out some dust and impurities therein. The air then enters the filtering device (9) to be filtered again. After the filtration is completed, the air enters the gas turbine through the air outlet (3); Step 2: When the folding device (5) needs to be cleaned, the third motor (403) is started to drive the limiting screw rod (402) to rotate. The limiting screw rod (402) rotates to drive the sliding inclined block (401) to move to the right for a certain distance. Then the second motor (501) is started. The second motor (501) drives the first gear (505) and the limiting rod (509) to rotate. The limiting rod (509) rotates to drive the support frame (504) to move. At the same time, through the meshing between the third gears (510), the support frame (504) is straightened on the movable frame (502) to form a plane. When the first gear (505) rotates, it drives the second support plate (508) to move inwards. At the same time, it drives the first support plate (507) to move inwards through the second gear (506), thereby releasing the limit on the movable frame (502); Step 3: Then start the first motor (701) to drive the rotating screw (706) to rotate, the rotating screw (706) rotates through the fixed block (503) to drive the movable frame (502) to move downward, and at the same time, the first worm (702) also rotates through the third worm wheel (805) to drive the third rotating rod (803) to rotate, and the third rotating rod (803) rotates through the second worm (804) to drive the roller brush (801) to rotate. When the movable frame (502) moves downward, the roller brush (801) rotates to perform preliminary cleaning on the filter cloth installed on the support frame (504), and then the fixed block (503) moves to the second rotating rod (707) and is lifted upward by the sliding plate (703); Step 4: The third rotating rod (803) continues to rotate, and then the cleaning liquid nozzle (810) sprays out the cleaning liquid. When the third rotating rod (803) rotates, the reciprocating screw (807) is driven to rotate through the fourth worm gear (806). The rotation of the reciprocating screw (807) drives the cleaning brush (808) to move up and down to wash the filter cloth. After the washing is completed, the water washing nozzle (809) sprays clean water to wash both sides of the filter cloth, the roller brush (801) and the water washing nozzle (809) to rinse the cleaning liquid. After the washing is completed, the water discharge is stopped; Step 5: The first worm gear (702) is then rotated in the opposite direction to drive the movable frame (502) back to its original position, and then the second motor (501) and the third motor (403) are started to adjust the folding angle of the support frame (504), and at the same time, the first support plate (507) and the second support plate (508) are driven to move and extend into the housing (1) to limit the movable frame (502). The water on the filter cloth can be left to dry naturally, or a drying device can be installed in the housing (1) to dry it.
