Fluidized bed reactor

Abstract

The present invention relates to the field of fluidized bed reactors, and discloses a fluidized bed reactor. The fluidized bed reactor comprises: a reactor main body (1) and a fluid distributor (2), wherein the reactor main body (1) comprises a reaction zone (4), wherein a plurality of fluid distribute holes (3) are formed in the bottom of the reaction zone (4), and the fluid distributor (2) comprises conveyor pipes that are connected with the fluid distribute holes (3), so that fluid materials can be conveyed to the reaction zone (4) by the conveyor pipes. The fluidized bed reactor disclosed by the present invention has the advantage that the fluid distributor is difficult to be corroded.

Description

technical field [0001] The invention relates to the field of fluidized bed reactors, in particular to a fluidized bed reactor. Background technique [0002] The fluidized bed reactor is a reactor that uses gas or liquid to pass through the granular solid layer to keep the solid particles in a state of suspension and movement, and to perform a gas-solid phase reaction process or a liquid-solid phase reaction process. At present, fluidized bed reactors have been widely used in chemical industry, petroleum, metallurgy, nuclear industry and other departments. [0003] like figure 1 As shown, the existing fluidized bed reactor generally includes a reactor body 1 with a reaction section 4 and a fluid distributor 2 (also known as a fluid distribution plate) arranged in the reactor body 1 and at the bottom of the reaction section 4, The fluid distributor 2 generally adopts a perforated plate design (such as figure 2 shown), the main function of the fluid distributor 2 is to make...

AI Technical Summary

Problems solved by technology

The existing fluid distributor 2 is generally arranged in the reactor body 1 and is located at the bottom of the reaction section 4 (that is, close to the reaction center of the fluidized bed reactor), so when the reaction material is corrosive (for example, it is used in the chlorination furnace) Chlorine gas is used as the fluid material), and the fluid distributor 2 is easily corroded. At the same time, because the fluid distributor 2 is close to the reaction center of the fluidized bed reactor, the heat released during the reaction makes the temperature of the reaction center of the fluidized bed reactor rise. Corrosive fluid materials are generally more corrosive at high temperatures, thereby aggravating the corrosion of the fluid distributor 2, thereby reducing the service life of the fluid distributor 2, making it unable to meet the needs of continuous production. The fluid distributor 2 will expand and deform, which will cause a gap between the fluid distributor 2 and the reactor body 1, causing the problem of poor sealing
