System and method for preparing iron oxyhydroxide desulfurizing agent

Abstract

The invention discloses a system and a method for preparing an iron oxyhydroxide desulfurizing agent. The system includes a base, wherein a box is fixedly mounted on the top of the base; the front andrear surfaces and the bottom surface of the box body are opened; a preparation box is fixedly mounted in the top of the base; preparation box located on inner side of box body, a first through hole is formed in the middle of the top surface of the box body, a motor is fixedly mounted at the top end of the first through hole, a vertical rotating shaft is arranged in the first through hole and connected with the inner wall of the first through hole through a bearing, the top end of the rotating shaft is fixedly connected to the output end of the motor, and the bottom end of the rotating shaft penetrates through the top of the preparation box and is connected with the inner bottom surface of the preparation box through a bearing. By means of the system, iron oxyhydroxide powder, the adhesive, the pore-forming agent and the auxiliary can be conveyed into the preparation box at the same time, and stirring can be conducted through the stirring blades in the conveying process, and conveying,stirring and mixing are conducted at the same time; the contents of the conveyed iron oxyhydroxide powder, adhesive, pore forming agent and assistant can be controlled, and the use is convenient.

Description

technical field [0001] The invention belongs to the field of desulfurizers, and in particular relates to a preparation system and method of an iron oxyhydroxide desulfurizer. Background technique [0002] Both industrial gas and exhaust gas contain a large amount of sulfide. The sulfide in industrial gas will cause poisoning and deactivation of catalysts in industrial production, shorten the service life of catalysts, increase the frequency of catalyst replacement, and thus increase costs. The direct discharge of sulfides in the gas will cause harm to the environment and humans and animals. Iron oxyhydroxide desulfurization is a new type of desulfurization agent, and the saturated sulfur capacity of the desulfurization agent is ≥30%. The content of hydrogen sulfide in the gas after desulfurization is ≤10mg / Nm3, and the desulfurizer can be regenerated and recycled, which greatly reduces the cost of desulfurizer required to remove sulfur per unit weight. desulfurization mate...
