Description

Technical Field

[0001] The utility model relates to the technical field of biogas filters, in particular to a biogas filter. Background Art

[0002] Biogas, also known as marsh gas or biogas, is a mixture consisting primarily of methane and small amounts of hydrogen sulfide, carbon dioxide, and trace amounts of phosphine that occurs naturally in certain geographical swamps, marshes, and bogs. The surface of swamps, marshes, and bogs is initially porous vegetation, which decays to form a crust that prevents oxygen from reaching the organic matter below. This is the condition that allows anaerobic digestion and fermentation of any plant or animal matter, which then produces methane. The trapped methane can escape through any of three main pathways: through the diffusion of methane molecules at the air-water interface, by bubbling out of the water in a process called boiling, or through plant-mediated transport. After purification, the quality of biogas can meet the national natural gas use standards, but biogas contains a large amount of impurities, which can easily cause damage to the purification equipment, and it is necessary to use a filter to filter the biogas before it is purified.

The bottom of the inner cavity of the filter barrel 6 is rotatably connected with a second screw rod 18, and a driven pulley 17 is sleeved on the outer side of the second screw rod 18. A transmission belt 16 is jointly provided on the outer sides of the driven pulley 17 and the driving pulley 14, and a movable block 20 is screwed on the outer side of the second screw rod 18, and an external scraper 10 is fixedly installed on the outer side of the movable block 20.

[0024] like Figure 1 As shown, three legs 1 are evenly and fixedly installed at the bottom of the base 2, and a foot support is fixedly installed at the lower end of each leg 1, so that the filter is supported at a certain height.

[0025] During implementation, an external scraper 10 and an internal scraper 21 are provided. By starting the motor 15, the active pulley 14, the driven pulley 17 and the transmission belt 16 are coordinated to control the synchronous rotation of the first screw rod 9 and the second screw rod 18, so that the movable plate 11 outside the first screw rod 9 drives the internal scraper 21 to rise and fall, and the movable block 20 outside the second screw rod 18 drives the external scraper 10 to rise and fall, so as to facilitate the cleaning of the inside and outside of the filter element 19, and solves the technical problem that the biogas filter is usually equipped with a filter element for filtering inside, but in actual use, impurities are easy to adhere to the filter element and cause blockage, which not only affects the filtering effect but also requires frequent cleaning.
