[0016] Working principle: When the present invention is used as an independent reaction device or a pipeline reaction device in a dry or semi-dry desulfurization and denitrification treatment system, the polluted flue gas enters the pipeline body through the air inlet end of the reaction device. A part of the airflow will be affected by the constraint of the blade when it contacts the surface of the rotor, thereby changing the flow direction of the airflow. This part of the deflected airflow will continue to act on the remaining airflow that has not contacted the rotor and change its flow direction accordingly, so that all the airflows passing through the pipeline body are transformed from a free-flowing linear flow path to a spiral flow path constrained by the rotor, and then flow out from the air outlet end of the reaction device; after the airflow enters the pipeline body, the powder nozzle located at the air inlet end of the pipeline body will simultaneously spray out reactants, which will mix with the airflow and undergo a gas-solid reaction on the spiral flow path, thereby achieving the purpose of removing corresponding harmful substances in the airflow; because the airflow is extended when it is transformed from a linear flow path to a spiral flow path The length of the flow path increases the airflow velocity, and the airflow will interact and mix during the change of direction, increasing the slip speed between gas and solid, thereby improving the reaction efficiency of the gas-solid reaction; the airflow has a higher flow velocity in the tangential direction of the outer circle of the spiral path, which improves the ability to blow away dust at the bottom of the pipeline and effectively reduces the probability of dust accumulation and agglomeration; the pulse module is mainly used in horizontally installed reaction devices, which can generate pulsed high-pressure jet airflow that fits the bottom of the pipeline body, effectively avoiding the generation of dust accumulation and effectively removing possible dust and scaling; the combined application of thermal insulation and temperature control modules, data detection modules, and circuit control modules can monitor and control factors such as temperature, pressure, wind speed, wind direction, and concentration in the pipeline body, providing an ideal reaction environment for gas-solid reactions in mixed dust and gas, and ensuring the stability of reaction efficiency; the auxiliary mechanism provides convenience for the rapid lifting, installation, maintenance, and replacement of the reaction device.
