[0007] Preferably, the intake direction of the intake pipe is tangent to the shell, so when the intake pipe transports sulfur-containing flue gas into the shell, the intake direction is tangent to the shell, which causes the entering flue gas to rotate along the inner side wall of the shell. This way, the solid calcium sulfate produced after spraying can be thrown to the inner side wall of the shell by centrifugal force, and the solid calcium sulfate, being heavy, can eventually slide down the shell to the collection bin. The escaped flue gas can be discharged to the outside of the device through the exhaust pipe.

[0008] Preferably, the lower end of the shell is fixedly provided with a collection bin, and the solid matters after flue gas spray desulfurization are conveniently collected inside the collection bin.

[0009] Preferably, the lower end of the exhaust pipe is fixedly provided with a filter bag, so that the solid matters after desulfurization in the flue gas can be further filtered by the filter bag in addition to the centrifugal force, and finally the solid matters can be collected at the lower end inside the collection bin.

[0010] Preferably, the upper end of the exhaust pipe is fixedly provided with a connecting flange, so that the flue gas after desulfurization treatment of the device can be conveniently connected with subsequent pipelines through the connecting flange.

[0011] Preferably, the lower end of the collection bin is provided with a sealing baffle, so that the solid impurities after desulfurization deposited at the lower end inside the shell can be discharged to the outside of the shell when needed by opening the sealing baffle.

[0012] Compared with the prior art, the device has the following beneficial effects:

[0013] 1. When the flue gas enters the inside of the shell, fine atomized treatment reagent can be sprayed into the lower end of the shell through the atomizing nozzle, then the flue gas can react with the treatment reagent, so that sulfidation solid matters can be quickly generated, and at this time, since the gas inlet direction is tangent to the shell, the entering flue gas will rotate along the inside side wall of the shell, so that the solid calcium sulfate generated after spraying can be thrown to the inside side wall of the shell by centrifugal force, and since the solid calcium sulfate is heavy, it can finally slide along the shell to the inside of the collection bin; and the flue gas after desulfurization can be discharged to the outside of the device through the exhaust pipe, so that the device integrates the cyclone dust removal equipment and the spraying system together, so that the flue gas can be quickly filtered after desulfurization, and the overall volume of the device can be significantly reduced, thereby facilitating use.

[0019] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a desulfurization and dust removal integrated spray type desulfurization device, including fixed frame 1, the fixed frame 1 upper end is provided with the spray mechanism of spray sulfur removal, the spray mechanism includes shell 2, air inlet pipe 3, exhaust pipe 4, isolator 5, connecting bin 6, interlayer 7, liquid inlet pipe 8, atomizing nozzle 9, the fixed frame 1 inside is fixedly provided with shell 2, one side of the shell 2 is fixedly provided with air inlet pipe 3, the inside middle part of the shell 2 is fixedly provided with exhaust pipe 4, the upper end of the shell 2 is fixedly provided with isolator 5, the outside of the exhaust pipe 4 is fixedly provided with connecting bin 6, the interlayer 7 is arranged between connecting bin 6 and exhaust pipe 4, one side of the connecting bin 6 is fixedly provided with liquid inlet pipe 8, the lower end of the connecting bin 6 is uniformly fixedly provided with a plurality of atomizing nozzles 9.

[0020] The air inlet direction of the air inlet pipe 3 is tangent to the shell 2, so when the air inlet pipe 3 transports sulfur-containing flue gas into the shell 2, the entering flue gas will rotate along the inside sidewall of the shell 2 due to the tangential air inlet direction, so that the solid calcium sulfate produced after spraying can be thrown to the inside sidewall of the shell 2 by centrifugal force, and the solid calcium sulfate can finally slide down to the inside of the collection bin 10 along the shell 2 due to its weight; and the escaped flue gas can be discharged to the outside of the device through the exhaust pipe 4;

[0021] The lower end of the shell 2 is fixedly provided with a collection bin 10, which facilitates the collection of solid substances after flue gas spray desulfurization in the inside of the collection bin 10;

[0022] The lower end of the exhaust pipe 4 is fixedly provided with a filter bag 11, so that the device not only filters the solid substances after desulfurization in the flue gas by centrifugal force, but also further filters the solid substances by the filter bag 11, so that the solid substances can finally accumulate in the lower end of the collection bin 10;

[0023] The upper end of the exhaust pipe 4 is fixedly provided with a connecting flange 12, which can conveniently connect the flue gas treated by the device to the subsequent pipeline;

[0024] The lower end of the collecting bin 10 is provided with a sealing baffle 13, through which the desulfurized solid impurities deposited at the lower end inside the shell 2 can be discharged to the outside of the shell 2 when needed.

[0025] Working principle: when using the device, the flue gas needing desulfurization is injected into the inside of the shell 2 through the air inlet pipe 3, and when the flue gas enters the inside of the shell 2, fine atomized treatment reagent (usually lye, lime milk, limestone slurry, etc., and at present most devices use lime milk as the absorbent) can be sprayed into the lower end of the inside of the shell 2 through the atomizing nozzle 9; then the flue gas can react with the treatment reagent, thereby quickly generating sulfidation solid, and at this time, since the inlet direction is tangent to the shell 2, the entering flue gas will rotate along the inside side wall of the shell 2, so that the solid calcium sulfate generated after spraying can be thrown to the inside side wall of the shell 2 by centrifugal force, and since the solid calcium sulfate is heavy, it can finally slide along the shell 2 to the inside of the collecting bin 10; and the desorbed flue gas can be discharged to the outside of the device through the air outlet pipe 4, so that the device integrates the cyclone dust removal equipment and the spraying system together, so that the flue gas can be quickly filtered after desulfurization, and the overall volume of the device can be significantly reduced, thereby facilitating use.
