BLOWING TANK WITH MULTI-CONE SEGMENT

BRIEF ABSTRACT

    A powder conveyance system with a multi-cone blowing tank is disclosed. The blowing tank has multi-cone segment and has multi-outlet pipe. The multi- outlet pipe allows the blowing tank to function even if one of the outlet-pipe fails. The multi-cone blowing tank provides higher reliability as a conveyance vessel in dry feed process.

DETAILED DESCRIPTION

    Generally, conveyance of powder like materials and dry substances over long distances is done by blowing tanks in which the powder is fluidized by entrained gas in high pressure tanks.

    There are a few challenges to designing a blowing tank for high moisture content powder conveyance. The challenges include pipe blockage, bridge formation at the outlet, and rat-holing in blowing tank. The aforementioned issues remain a challenge and lead to failure of powder conveyance from the blowing tank to a downstream device.

    Conventionally, powder conveyance systems dry the powder completely to reduce rat-holing tendency in blowing tanks. Further, conventional methods control the powder size strictly before loading into blowing tanks and also to inset inner construction to resist the bridge formation. However, conventional methods are not reliable and do not overcome all the problems of powder conveyance in a definite manner.

    Therefore, there is a need in the art for a more reliable and efficient blowing tank for a dry feed process.

    Figure 1 illustrates a powder conveyance system with a multi-cone blowing tank. As shown in Figure 1, the powder conveyance system has a side discharging blowing tank. The side discharging blowing tank has multi-cone segments. The multi-cone blowing tank acts as a sending vessel in dense phase pneumatic conveyance system. The powder conveyance system described herein has two parts, a top cylindrica...
