However, after the flue gas is introduced into the desulfurization tower, it is easy for the flue gas to react with the adsorbent in the bottom material pipe of the distributor during its upward movement, forming agglomerates and causing blockage at the bottom material pipe of the distributor, thereby causing the desulfurization reaction efficiency to gradually decrease.

[0008] Preferably, both sides of the desulfurization tower are respectively connected with a smoke inlet and a smoke exhaust outlet.

[0009] Preferably, a connecting pipe is fixedly installed on the top of the adsorbent spray plate, and the connecting pipe is fixedly connected to the bottom end of the adsorbent inlet.

[0010] Preferably, the adsorbent spray plate is a hollow structure, and the bottom connecting nozzle of the adsorbent spray plate corresponds one to one with the top connecting seat of the distributor.

[0011] Preferably, the adsorbent spray plate slides in the inner wall of the desulfurization tower, and the return spring is used to elastically return the adsorbent spray plate.

[0012] Preferably, the connecting nozzle is a tubular structure, and the bottom end of the connecting nozzle passes through the connecting seat and extends into the inner wall of the material pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model connects the adsorbent spray plate with the adsorbent inlet through the bottom corrugated connecting pipe, so that the adsorbent can be introduced into the bottom material pipe of the distributor through the connecting nozzles evenly distributed at the bottom of the spray plate, and then the gas at the smoke inlet on one side of the desulfurization tower can be desulfurized. After a cycle, the electric push rod can be energized, and the telescopic end of the electric push rod can push the adsorbent spray plate and the bottom connecting nozzle downward, and the bottom end of the connecting nozzle extends through the connecting seat to the material pipe, and then the agglomerated part of the inner wall of the material pipe can be dredged, thereby avoiding the blockage of the material pipe caused by the agglomeration of sulfides in the material pipe.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 The utility model provides a technical solution: a dry desulfurization device, including a desulfurization tower 1, a distributor 3, and a material pipe 31. The top of the desulfurization tower 1 is connected with an adsorbent inlet 13, and the inner wall of the desulfurization tower 1 is provided with an adsorbent spray plate 2. The bottom of the adsorbent spray plate 2 is connected with connecting nozzles 21 at equal intervals, and the distributor 3 is fixedly installed in the inner wall of the desulfurization tower 1;

[0022] A material pipe 31 is connected through the bottom of the uniform distributor 3, and a connection seat 32 is fixedly installed at an equal interval on the top of the uniform distributor 3. An electric push rod 4 is installed between the adsorbent spray plate 2 and the inner wall of the desulfurization tower 1, and a return spring 5 is installed between the two sides of the adsorbent spray plate 2 and the desulfurization tower 1;

[0023] The adsorbent inlet 13 can continuously introduce the adsorbent into the desulfurization tower 1, and the adsorbent is evenly distributed in the desulfurization tower 1 through the distributor 3 and the bottom material pipe 31 in the desulfurization tower 1, and the desulfurized gas introduced at the smoke inlet 11 on one side of the desulfurization tower 1 can fully contact with the adsorbent, so as to adsorb and desulfurize the sulfide in the gas. The desulfurization of the sulfide gas by the adsorbent is a prior art and will not be described in detail here.

[0024] The adsorbent spray plate 2 is connected to the adsorbent inlet 13 through the bottom corrugated connecting pipe 6, so that the adsorbent can be introduced into the bottom material pipe 31 of the distributor 3 through the connecting nozzles 21 evenly distributed at the bottom of the spray plate, and then the gas at the smoke inlet 11 on one side of the desulfurization tower 1 can be desulfurized. After a cycle, the electric push rod 4 can be energized, and the telescopic end of the electric push rod 4 can push the adsorbent spray plate 2 and the bottom connecting nozzle 21 downward. The bottom end of the connecting nozzle 21 passes through the connecting seat 32 and extends into the material pipe 31, and then the agglomerated part of the inner wall of the material pipe 31 can be dredged, thereby avoiding the sulfide agglomeration in the material pipe 31 from causing blockage of the material pipe 31. Compared with the existing dry desulfurization device, the agglomerates in the bottom material pipe 31 of the distributor 3 can be cleaned, so that the adsorbent can be evenly distributed in the desulfurization tower 1, ensuring the normal operation of the desulfurization in the desulfurization tower 1.

[0027] Among them, the adsorbent spray plate 2 slides in the inner wall of the desulfurization tower 1, and the return spring 5 is used to elastically return the adsorbent spray plate 2. After the material pipe 31 is unblocked through the connecting nozzle 21, the electric push rod 4 is powered off by the controller, and the adsorbent spray plate 2 can be elastically returned to the top of the inner cavity of the desulfurization tower 1 through the return springs 5 ​​on both sides.

[0029] Working principle: When in use, the adsorbent inlet 13 can continuously introduce the adsorbent into the desulfurization tower 1, and the adsorbent is evenly distributed in the desulfurization tower 1 through the distributor 3 and the bottom material pipe 31 in the desulfurization tower 1, and the desulfurized gas introduced at the smoke inlet 11 on one side of the desulfurization tower 1 can fully contact with the adsorbent, thereby adsorbing and desulfurizing the sulfide in the gas;

[0030] After one cycle, the electric push rod 4 can be energized, and the telescopic end of the electric push rod 4 can push the adsorbent spray plate 2 and the bottom connecting nozzle 21 downward, and the bottom end of the connecting nozzle 21 passes through the connecting seat 32 and extends into the material pipe 31, thereby clearing the agglomerated part of the inner wall of the material pipe 31, thereby avoiding the blockage of the material pipe 31 caused by the agglomeration of sulfides in the material pipe 31.
