What is Fluidized Bed Reactor?

Filson fluidized bed reactor is a kind of chemical reactor that uses gas or liquid to pass through the granular solid layer, and thus keep the solid particles in suspension and carry out gas-solid phase reaction process or liquid-solid phase reaction process.

Except for fixed bed reactor, Filson fluidized bed reactor is the most widely used reactor type in industry, suitable for fluid-solid or gas-liquid-solid catalytic reaction and non-catalytic reaction. When used in gas-solid systems, the device is also known as boiling bed reactor.

Fluidized bed reactor has long history in modern industry since 20 century. With further updates and upgrades, Filson fluidized bed reactor is widely applied to various industries including chemicals, pharmaceuticals and nuclear field.

Main Categories of Fluidized Bed Reactor

Filson anaerobic fluidized bed reactor is an ideal choice for wastewater treatment. In the reactor, the oxidation of organic matters is not complete, which releases less energy, so the conversion rate of organic matter is slow and takes a long time.

Aerobic Fluidized Bed Reactor

On the contrary to anaerobic fluidized bed reactor, Filson aerobic fluidized bed reactor is more efficient with high conversion rate in a relatively small equipment. With reasonable structure design, the reactor becomes welcomed in the industry.

When the rate increases, rapid upward flow bubbles occur within Filson bubble fluidized bed reactor system, promoting uniform mixing of particles and facilitating temperature management. It also has large reaction area and low pressure drop.

As an unique device to improve combustion efficiency by circulation, Filson circulating fluidized bed reaction is able to absorb up to 95% of pollutants and avoid emission into air. It is made of superior metals and is resistant to high heat and corrosion.

Filson fluidized bed catalytic reactor is a chemical reactor which is used to carry out reactions under the action of catalyst. In a FBCR, a bed of solid catalytic particles is suspended in a flow of a gaseous or liquid reactant to promote the reaction rate.

Fluidized Bed Reactor for Wastewater Treatment

Fluidized Bed Reactor FAQ Guide

What is AFluidized Bed Reactor?

Fluidized bed reactor is a vessel or chemical reactor where some reactions take place. It is a robust container engineered with certified construction materials, such as stainless steel, Hastelloy, Titanium, Monel and Nickel.

In a fluidized bed reactor, the reactants enter from the bottom and do an upper movement. The reactants could be both gas and liquid. As the reactants move, the solid layer inside the vessel is kept in suspension state.

What is Fluidized Bed Reactor Working Principle?

Fluidized bed reactor is proven outstanding and effective in gas-solid phase reaction process and liquid-solid-gas phase reaction process. The detailed working principle is as follows:

Fluid (gas or liquid) with a high flow rate passes through the fluidized bed, driving the movement of solid particles in the bed, so that it is suspended in the flow of the main stream for reaction. And due tothe characteristics similar to fluid flow, it is called fluidized bed reactor.

Fluidized bed reactor is a kind of reactor with the participation of solid particles, these particles are in motion. And the direction of their movement is varied, which is different from the fixed bed reactor.

What is Backmixing Inside AFluidized Bed Reactor?

What is Backmixing Inside A Fluidized Bed Reactor

Backmixing, also known as reverse mixing, is a mixing phenomenon. It refers to the continuous process of material mixing caused by the movement in the opposite direction to the mainstream.

The presence of such mixing affects the concentration distribution and temperature distribution along the mainstream direction, causing the concentration to tend toward the outlet concentration.

For the reaction process of fluidized bed reactor, backmixing decreases the reactant concentration and increases the product concentration. On this account,it results in a decrease in the primary reaction rate and an increase in the series by-reaction rate. What’s more,the reaction selectivity is also decreased.
