Activated carbon desulfurization and denitrification conveying rotary valve

Abstract

The invention provides an activated carbon desulfurization and denitrification conveying rotary valve. The activated carbon desulfurization and denitrification conveying rotary valve is provided witha valve body; a cylindrical inner cavity body is disposed in the valve body; a material inlet is formed in the valve body; a right end cover and a left end cover are disposed on the two sides of the valve body correspondingly; the valve body is in sealed connection with the right end cover and the left end cover; a rotor rotationally penetrates through the right end cover and the left end cover; the rotor comprises a main shaft and a valve clack; the main shaft penetrates through the right end cover and the left end cover and is rotationally connected with the right end cover and the left endcover; the valve clack is fixed to the main shaft and located in the cylindrical inner cavity body and is in a curved surface shape; and conveyed activated carbon can be formed in a coated state whenthe curved-surface-shaped valve clack rotates. The technical problems that in an existing activated carbon dry desulfurization and denitrification device, the activated carbon particles are broken after falling, being abraded and being shorn by a rotary device during transferring in a circulation conveying system is solved. The activated carbon desulfurization and denitrification conveying rotaryvalve can be widely applied to the field of activated carbon desulfurization and denitrification conveying.

Description

technical field [0001] The invention relates to a rotary valve, in particular to a rotary valve used for desulfurization and denitration of activated carbon, and belongs to the field of environmental engineering. Background technique [0002] We know that the existing technical principle of activated carbon dry desulfurization and denitrification is mainly based on the presence of H 2 O and O 2 Under certain conditions, the SO in the flue gas is removed by physical and chemical adsorption processes 2 , under the catalytic action of activated carbon, NOx in the flue gas reacts with ammonia to form N 2 , using the rich microporous structure of activated carbon to physically adsorb and remove HCl, HF, dioxins and heavy metals, in a set of activated carbon dry desulfurization and denitrification device, the purification of various pollutants is realized, and the adsorption of SO 2 The activated carbon is recycled after regeneration, and the released sulfur dioxide gas can be ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problem of large activated carbon particle size classification and screening in the existing activated carbon dry desulfurization and denitrification device and the large consumption of activated carbon in the process of classification and screening, and provides a rotary valve for the feeding and discharging device installed at the inlet and outlet of the adsorption tower, which can Realize the continuous feeding and discharging of the adsorption tower, and reduce the damage of activated carbon
