Embodiment Construction
[0015] Such as figure 1 As shown, it is a dry desulfurization device of the present invention, which includes a calciner 1, a desulfurization tower 2, and a dust collector 3. The calciner 1 is provided with a combustion zone 4 and a desulfurizer bin 5 arranged below the combustion zone 4. Combustion The area 4 and the desulfurization agent bin 5 are separated by a separation device. The desulfurization agent bin 5 and the desulfurization tower 2 are connected by a screw conveyor 6. A smoke inlet device is installed above the desulfurization tower 2. A screw conveyor is installed inside the desulfurization tower 2. Conveyor 6 is connected with the sprinkler device.
[0016] Specifically, the bulk desulfurizer is burned into small particles in the calciner 1, and flows into the desulfurization tower 2 through the screw conveyor 6 to be mixed with flue gas to remove sulfur dioxide and other gases in the flue gas.
[0017] The separation device includes an asbestos net 7 , an inc...

The invention discloses a dry desulfurization device, and relates to the technical field of flue gas purification. The device comprises a calcining furnace, a desulfurizing tower and a dust remover, aburning area and a desulfurizing agent chamber arranged below the burning area are arranged in the calcining furnace, and the burning area and the desulfurizing agent chamber are isolated by a separating device; the desulfurizing agent chamber is connected with the desulfurizing tower through a spiral conveyer, a flue gas inlet device is arranged above the desulfurizing tower, and a spraying device communicated with the spiral conveyer is arranged in the desulfurizing tower. According to the dry desulfurization device, a desulfurizing agent forms into small particles through burning to be sprayed to and uniformly mixed with flue gas, the desulfurizing efficiency is increased, in addition, and an air source can be utilized to provide energy required by all parts in the technology process.
