Abstract

The invention discloses an efficient dust removal, desulfurization and denitrification device for a boiler. The device comprises a dust remover and an adsorption tower which are communicated, whereinan inner cavity of the adsorption tower body is divided into an adsorption chamber and an ammonia supply chamber, a second gas inlet pipe and a second gas outlet pipe are arranged in the adsorption chamber, an ammonia inlet pipe is communicated with the side part of the ammonia supply chamber, a support pipe is rotationally connected to a partition board, the lower end of the support pipe is communicated with an inner cavity of the ammonia supply chamber, and a propeller blade is fixed on the outer side of the support pipe, and a body of the propeller blade is filled with a silk screen, guideholes provided with one-way valves inside are formed in the position, close to the top, of the support pipe, and the upper end of the support pipe is fixedly connected with an output shaft of a seconddriving motor through a coupler. The device is reasonable in structural design, the adsorption tower adopts an activated coke adsorption method for desulfurization and denitrification, no water is used, no secondary pollution is caused, the silk screen in a propeller blade shaft forcefully and downwards transfers activated coke powder rising with smoke, and effective conduction of desulfurizationand denitrification can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-efficiency boiler dust removal, desulfurization and denitrification device. Background technique [0002] SO emitted from coal combustion 2 and NO x is the main cause of air pollution, and the current control of SO 2 and NO x One of the most effective means of emission is the integration of desulfurization and denitrification. Today, simultaneous desulfurization and denitrification technology has become a cutting-edge research direction in the field of air pollution control because of its advantages in achieving simultaneous desulfurization and denitrification in the same system. Generally speaking, simultaneous desulfurization and denitrification technologies can be divided into three categories according to the state of the removal agent and the reaction product. The wet process is mature, high in efficiency, and widely used, but there are...
