Title: Method and device for preventing dust release in bag filter
Inventor: MATSUI YOSHIO
IPC: B01D46/02
Filed: 1992-03-06
Abstract: PURPOSE:To provide a method and a device for preventing dust release in a bag filter where dust release in the air due to dust blow-through immediately after blow-off is effectively prevented and a sudden increase in bag differential pressure and shortening of bag life are prevented. CONSTITUTION:When the differential pressure between the inside and outside of a bag 2 in a dust removing chamber R1 reaches the prescribed value, a outlet side damper N1 is closed and simultaneously a damper J1 for blow-off is opened to operate a circulating fan F3. A pulse valve S1 is operated in this state to jet compressed air in a pressure tank P into the bag 2, causing dust deposited on outer surface of the bag 2 to be blown off. When blow-off work is completed, a pulse valve S1 is closed and simultaneously an inlet side damper M1 is opened again to continue dust collecting work. During this period, if dust is fine and strong in adhesiveness, a precoat agent H1, such as coal ash, slaked lime and diatomaceous earth is fed to the inlet side of the dust removing chamber R1 to form a precoated layer on the outer surface of the bag 2. After that, the outlet side damper N1 is opened and simultaneously the blow-off damper J1 is closed to restore the normal operation.

Inventor: HAMAZAKI HIKOICHI
IPC: C10L5/36
Filed: 1981-05-29
Abstract: PURPOSE: To accelerate oxidation of CO and to reduce evolution of CO, by providing the upper portion of a briquet with a horizontal passage from the peripheral surface until said passage communicates with at least a peripheral- side air passage among air passages penetrating the briquet.  
     CONSTITUTION: The upper portion of a briquet 1 is provided with a horizontal passage 2a from the peripheral surface until said passage 2a communicates with at least a peripheral-side air passage 2 among passages penetrating the briquet 1. Upon ignition of the briquet, not only the upper surface flames up with air supplied via the air passage, but also the peripheral surface burns forming a long flame with air supplied via the peripheral-side air passage and partially via the horizontal passage 2a to the peripheral surface. Therefore, the peripheral surface of the upper portion as well as the upper surface of the briquet is entirely covered with flame, and complete combustion is attained in a short time after the ignition, which accelerates oxidation of CO evolved from the briquet.

Abstract: PURPOSE:To enable a dielectric sheet to hold a transfer material by sufficiently strong electrostatic attraction force and to excellently transfer a toner image when the toner image is transferred by providing an electric discharge means between the feeding path of the transfer material to the dielectric sheet and the dielectric sheet. CONSTITUTION:The grounded self electric discharge wire 22 is disposed between the transfer material P and the transfer material carrying member of a transfer drum 9, that is, and on the upstream side of a contact point 21 of the transfer material P with the dielectric sheet 93. Then, when a gap between a photosensitive drum 3 and the sheet 93 becomes small, atmospheric discharge occurs. Besides, negative electric charge is injected on the sheet 93 and positive electric charge is injected in the drum 3 side. The negative electric charge on the sheet 93 is injected in the material P and the material P is electrostatically charged to negative. Therefore, since the material P is passed through an electric field forming zone where an electric field proceeding to the drum 3 from the sheet 93 is formed under a state that it is electrostatically charged to negative, the electrostatic attraction force of the material P to the sheet 93 becomes strong.
