Powder Handling & Processing

[Abstract]:
During powder Handling and processing, there are many applications in solid mixing, exhausting, boiling and discharging process with Shinkai sinter metal porous elements.

    Shinkai sinter metal elements can prevent preventing bridging,rat holing and sagging in bulk powders by producing even flow characteristics, as well as the formation of dead-spaces which can lead to product aging. The venting cones gently agitate powders,dramatically reducing particle friction ,which in turn results in an even discharge from vessels and thus improvement of the product. Shinkai sinter metal cones can additionally function as mixing or homogenization beds,thereby avoiding the need of an additional discharge element. The pore size of individual Shinkai sinter metal cones can be adapted to the powder particle size.

 

    The elements can be used to great effect in all areas of bulk powder processing .They prevent discharge problems by maintaining continuous flow, they tolerate high temperatures and offer a homogeneous gas through flow across the entire surface area . They are equally suitable for use with high pressure differentials and through-flow rates, and in corrosive environments. Shinkai sinter metal elements are exceptionally long-lasting and require little maintenance. they produce no harmful vibration ,are easy to install and refit, which minimal gas consumption.

In the HT-L, SHELL or GSP pulverized coal pressure gasification devices can be transported by pulverized coal. Transportation medium is N2 or CO2, normally, the most important part is pulverized coal forcing and transportation system in this technology. It will cause bridging problem due to solid particle in gas media occurring inattentive adhesion phenomenon. Nitrogen can enter into tank through aeration cone in the bottom of coal powder charging bucket and make powder homogenization and reduce acting force among powder so as to make particle smooth fluid under the effect of gravity after aeration cone added.

Pipe purge device is also very important in pulverized coal forcing transportation technology. The pipe is blocked easily and material is not transported smoothly due to coal powder accumulated together in high pressure, so that we will add pipe purge device in transportation pipeline so as to solve this problem effectively. The reason is that gas form uniform film n inside wall of purge device and powder presents as suspended and fluidized state, thereby, it can flow into next running pipe smoothly and avoid powder accumulation so as to increase transportation effect when gas penetrated through purge device inside micro pore.
