Detailed Description
As shown in fig. 1, a sulfur dioxide flue gas three-in-one conversion device comprises an electric furnace 2 and a converter 9. An electric heating pipe 3 is arranged on the inner wall of the electric furnace 2; one side of the electric furnace 2 is provided with an electric furnace flue gas inlet 1, the other side is provided with a flue gas outlet connecting pipe 13, and the top is provided with a hoisting hole 4 and a seal head 5; a converter 9 is arranged in the electric furnace 2, and one side of the converter 9 is connected with a flue gas outlet connecting pipe 13 through a converter flue gas outlet 12; the top of the converter 9 is provided with a converter flue gas inlet 7, and the converter flue gas inlet 7 is positioned below the end enclosure 5; the converter 9 is internally provided with a gas distribution plate 8, a catalyst 10 and a grate plate 11 from top to bottom in sequence, and the upper part of the outer wall of the converter is provided with a baffle plate 6.
The manufactured converter 9 is placed into the electric furnace 2 from a hoisting hole 4 of the electric furnace 2, the converter 9 is fixed, a converter flue gas outlet 12 is connected with a flue gas outlet connecting pipe 13, a grate plate 11 is installed, a catalyst 10 is loaded, and after an air distribution plate 8 and a baffle plate 6 are installed, an end enclosure 5 is installed to seal the equipment. The space formed by the converter 9 and the electric furnace 2 corresponds to a heat exchanger. The baffle plate 6 controls the flow direction of the flue gas, and ensures that the flue gas is uniformly and fully heated in the electric furnace 2. The gas distribution plate 8 is used to ensure the flue gas to enter the catalyst 10 uniformly for conversion reaction.
When the electric furnace is in work, the electric heating pipe 3 is opened, sulfur dioxide flue gas enters the electric furnace 2 from the electric furnace flue gas inlet 1, the flue gas is heated and heated in the electric furnace 2, the quantity of the electric heating pipe 3 is opened through control, the flue gas heating temperature is controlled, the flow direction of the flue gas is controlled by the baffle plate 5, the sulfur dioxide flue gas is enabled to enter the converter 8 through the converter flue gas inlet 7 after the flue gas is fully and uniformly heated in the electric furnace 2, and conversion reaction is carried out. When the sulfur dioxide flue gas is converted into sulfur trioxide flue gas, the conversion reaction of the flue gas is completed. At this time, the sulfur trioxide flue gas enters the next process through the converter flue gas outlet 12 and the flue gas outlet connecting pipe 13.
