The most commonly used flue gas desulfurization processes mainly include a wet process (lime/limestone-gypsum process), a semi-dry process (spray drying process), an absorption regeneration process, a calcium spraying-humidification activation process, and the like.
However, in the actual operation process, because the desulfurization efficiency is low and the reaction is incomplete, the utilization rate of the desulfurizing agent is not high, and the environmental protection cost is increased, so that it is necessary to research a device to solve the above problems.

In a preferable scheme, a secondary auxiliary throat and a secondary auxiliary flaring are further arranged at the bottom of the desulfurization tower before clean flue gas enters the tower, and the auxiliary desulfurizer adding port is formed in the secondary auxiliary throat.
According to the preferred scheme, the uniformly distributed calandria is made of high-carbon steel.
The utility model discloses the advantage:
1. the method is characterized in that a Venturi tube device is arranged before flue gas enters a tower, a main desulfurizer adding port is arranged at the throat of the Venturi tube, the desulfurizer is mixed into high-speed flue gas by utilizing a negative pressure effect, and the desulfurizer is fully mixed with the flue gas through a turbulence effect generated by inlet flaring (when the flow speed is changed sharply, fluid generates violent turbulence). The arrangement fully utilizes the flue space, not only reduces the occupied space of equipment, but also greatly prolongs the mixing reaction time of the desulfurizer and the flue gas and improves the desulfurization efficiency;
2. the uniformly distributed calandria is arranged in front of the flue gas outlet, so that the flue gas in the tower body is uniformly distributed, the problem of insufficient reaction caused by too high local flow speed is solved, meanwhile, a turbulent flow area is formed above the uniformly distributed calandria by reusing the Venturi principle, the contact time of the desulfurizer and S02 is prolonged, and the reaction efficiency is improved;
3. and the bottom of the desulfurization tower and the lower part of the flue gas inlet are provided with auxiliary desulfurizer adding ports, and the desulfurizer is recycled in the storage bin.
