BULK SPHERICAL FILTER WITH AUTOMATIC SELF-REGENERATION Russian patent published in 2022 - IPC B01D46/30 

FIELD: filters.

SUBSTANCE: bulk spherical filter with automatic self-regeneration, designed for dry cleaning of gases from dust, can be used in aspiration systems of food, construction, machine-building, pharmaceutical, metallurgical, woodworking and other industries. The filter contains spherical case 2, filter cassette with bulk material 3 mounted on shaft 8. Case 2 smoothly transitions into a cone-shaped inlet pipe of dusty air 1, located at the bottom, and a cone-shaped outlet pipe of purified gas 6, located at the top. In this case, spherical filter cassette 3 consisting of sectors made of metal mesh and fastened with stiffening arcs 7 is mounted on a shaft rotated for regeneration using electric engine 4, located perpendicular to the axis of the case, to maintain a spherical shape of the filter cassette filled with bulk filter material 10, the size of which depends on properties of a dust and gas flow. On the side of the supply of dusty gas, circular guide 5 is installed locking blockages.

EFFECT: increase in the efficiency of purifying the dust and gas flow from dust by redistributing the dust and gas flow over the filter surface and effective automatically triggered self-regeneration of bulk filter material by rotating a spherical filter cassette using an electric engine.
