Upper straight-down rotating dry-type circulating fluidized bed desulfurization reactor

Abstract

The invention discloses a desulphurization reactor of an upper direct-lower rotary dry-type circulating fluidized bed and relates to a desulphurization reactor of the circulating fluidized bed. The reactor solves the problems that the prior desulphurization reactor has low working efficiency and particles are easy to cling to the wall surface and the prior desulphurization reactor has large height. An inner cylinder is arranged in an outer cylinder; the lower end of the inner cylinder is positioned on the lower part of the outer cylinder; a swirler is arranged at the upper end of the inner cylinder; one to four tangential cyclone smoke exhaust pipes are positioned on the lower part of the outer cylinder and are evenly distributed on the outer sidewall of the inner cylinder along the tangential direction; each tangential cyclone smoke exhaust pipe is communicated with a cavity between the outer cylinder and the inner cylinder; the upper end of the shell is communicated with an inner cavity of the outer cylinder; the lower end of the shell is communicated with the inner cylinder; one side of each cyclone plate is connected with a central shaft; and the other side of each cyclone plate is connected with the inner wall of the shell. The desulphurization reactor has a compact structure, strong applicability of load change and low cost and is convenient for general layout and operating maintenance of the system; and the desulphurization efficiency is improved over 10 percent.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to an upper straight-down spin dry circulating fluidized bed desulfurization reactor. Background technique [0002] The desulfurization reactor is the core device of the desulfurization process, and the fluidization technology has been widely used in energy, environmental protection and chemical engineering fields. The circulating fluidized bed flue gas desulfurization reactor uses absorbents such as slaked lime as the circulating material. Under the action of the flue gas, the circulating material is fluidized in the reactor, and the sulfur dioxide in the flue gas and the absorbent in the circulating material undergo a neutralization reaction. , to achieve the purpose of desulfurization. The problems existing in the existing circulating fluidized bed desulfurization reactor are as follows: 1. During the operation of domestic boilers, the load of the unit changes grea...
