Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] like Figure 1-6 As shown, in this embodiment, a fly ash treatment device of a waste incineration power plant includes a first box body 1, a second box body 2, a fly ash treatment component 3 and an output component 4, the second box body 2 is arranged on one side of the first box body 1, the fly ash treatment component 3 is arranged in the first box body 1 and the second box body 2, and the output component 4 is arranged on one side of the second box body 2;

[0027] The fly ash processing assembly 3 includes a first mixer 31, a smoke input pipe 311, a second mixer 32 and a second mist input pipe 321; the first mixer 31 is rotatably connected in the first box body 1; the smoke input pipe 311 is fixedly connected in the first box body 1, the first mist input pipe 312 is fixedly connected in the first box body 1, a first empty groove 313 is opened on one side of the first box body 1, and a first filter plate 314 is slidably engaged in the first empty groove 313; the second mixer 32 is rotatably connected in the second box body 2; the second mist input pipe 321 is fixedly connected in the second box body 2, a second empty groove 322 is opened on one side of the second box body 2, and a second filter plate 323 is slidably engaged in the second empty groove 322.

[0028] In the specific implementation, the flue gas mixed with fly ash is input into the first box body 1 through the flue gas input pipe 311, and then the alkaline mist is input into the first box body 1 through the first mist input pipe 312. At the same time, the first mixer 31 is started to rotate clockwise. The first mixer 31 mixes the alkaline mist with the flue gas and neutralizes the fly ash therein. Then, the treated flue gas is initially filtered through the first filter plate 314 in the first empty slot 313 and enters the second box body 2. At this time, the acid mist or its His curing agent is selectively input into the second box body 2 through the second mist input pipe 321 according to the chemical composition of the flue gas discharged into the second box body 2. At this time, the second mixer 32 is started to mix the flue gas and the acid mist or the fixing agent. The acid mist is used for acid-base neutralization, and the curing agent is used to solidify the heavy metals in the fly ash. It should be noted that after the alkaline mist neutralizes the fly ash with acid and alkali, the acid mist can be used for acid-base neutralization again only when the alkalinity is high. In addition, the detection of the composition of the flue gas is a prior art and will not be elaborated on.

[0029] like Figure 5As shown, further, the first mixer 31 and the second mixer 32 each include a first motor 33, a stirring rod 331 and a rotating paddle 332; the two first motors 33 are respectively fixedly connected to the outside of the first box body 1 and the second box body 2; the two stirring rods 331 are respectively fixedly connected to the driving ends of the two first motors 33, and the two stirring rods 331 extend into the first box body 1 and the second box body 2 respectively; the two groups of rotating paddles 332 are respectively fixedly connected to the outside of the two stirring rods 331.

[0030] During specific implementation, the first motor 33 drives the stirring rod 331 to rotate, and the stirring rod 331 drives the rotating blade 332 to rotate to mix the smoke.

[0031] like Figure 2 and Figure 3 As shown, further, the number of the first empty slots 313 and the second empty slots 322 are both two, and a guide plate 34 is provided on one side of the two first empty slots 313 and the second empty slots 322, and the two groups of guide plates 34 are fixedly connected to one side of the first box body 1 and the second box body 2 respectively.

[0032] In a specific implementation, the guide plate 34 is used to guide the smoke, and the two guide plates 34 are both arranged to be tilted downward, so as to prevent the smoke from flowing back when the first mixer 31 and the second mixer 32 rotate clockwise.

[0033] like Figure 2 As shown, further, the opening of the smoke input pipe 311 faces downward, and the openings of the first mist input pipe 312 and the second mist input pipe 321 face upward and tilted to one side.

[0034] In specific implementation, the opening of the smoke input pipe 311 faces downward to prevent smoke backflow, and the openings of the first mist input pipe 312 and the second mist input pipe 321 face upward and tilt to one side, so that the mist can rotate more smoothly with the first mixer 31 and the second mixer 32 and be fully mixed.

[0035] like Figure 2 As shown, further, the bottoms of the first box body 1 and the second box body 2 are both funnel-shaped, and the bottoms of the first box body 1 and the second box body 2 are fixedly connected with a discharge pipe 35, and the bottom ends of the two discharge pipes 35 are movably connected with a waste box 351.

[0036] During specific implementation, after acid-base neutralization and heavy metal solidification, the fly ash will fall to the bottom of the first box body 1 and the second box body 2, and fall into the waste box 351 through the discharge pipe 35. The waste box 351 can be snapped onto the bottom of the discharge pipe 35 and fixed by bolts. After being filled with fly ash, it can be disassembled and cleaned.

[0037] In addition, if Figure 1-4As shown, the two first filter plates 314 and the second filter plates 323 are slidably engaged in the first empty slot 313 and the second empty slot 322, and their outer ends extend out of the first box body 1 and the second box body 2. After the first filter plates 314 and the second filter plates 323 are full of dust, they can be pulled out from the first box body 1 and the second box body 2 in time for cleaning. Example

[0038] like Figure 6 As shown, in this embodiment, the output component 4 includes an output box 41, a cylinder 42, a second motor 421 and an output tube 43; the output box 41 is fixedly connected to one side of the second box body 2; the cylinder 42 is fixedly connected to the upper end of the output box 41; the second motor 421 is fixedly connected in the cylinder 42, and the driving end of the second motor 421 is fixedly connected with a plurality of fan blades 422; the output tube 43 is fixedly connected to the bottom end of the output box 41.

[0039] In specific implementation, the treated flue gas will be filtered through the second filter plate 323 in the second empty slot 322 and enter the output box 41. At this time, the second motor 421 is started, and the second motor 421 drives the multiple fan blades 422 to rotate, generating airflow, increasing or slowing down the flow rate of the flue gas, thereby speeding up the flue gas or slowing down the speed of discharge through the output pipe 43.

[0040] like Figure 6 As shown, further, the waterproof box 44 is fixedly connected to the output box 41 , and a fresh air outlet 441 is opened on one side of the waterproof box 44 .

[0041] In specific implementation, the fresh air inlet 441 is opened on the side surface of the waterproof box 44 instead of the upper end surface, so as to effectively input fresh air while waterproofing.

[0042] Working principle: First, the flue gas mixed with fly ash is input into the first box body 1 through the flue gas input pipe 311, and then the alkaline mist is input into the first box body 1 through the first mist input pipe 312. At the same time, the first mixer 31 is started to rotate clockwise. The first mixer 31 mixes the alkaline mist with the flue gas and neutralizes the fly ash therein with acid and alkali. Then, the treated flue gas is initially filtered through the first filter plate 314 in the first empty slot 313 and enters the second box body 2. At this time, the acid mist or other curing agent is selectively input into the second box body 2 through the second mist input pipe 321 according to the chemical composition of the flue gas discharged into the second box body 2. At this time, the first mixer 31 is started to rotate clockwise. The first mixer 31 mixes the alkaline mist with the flue gas and neutralizes the fly ash therein with acid and alkali. Then, the treated flue gas is initially filtered through the first filter plate 314 in the first empty slot 313 and enters the second box body 2. At this time, the acid mist or other curing agent is selectively input into the second box body 2 through the second mist input pipe 321 according to the chemical composition of the flue gas discharged into the second box body 2. The second mixer 32 is driven to mix the flue gas and the acid mist or the fixing agent. The acid mist is used for acid-base neutralization, and the curing agent is used for curing the heavy metals in the fly ash. During the treatment of the flue gas, the fly ash will fall to the bottom of the first box body 1 and the second box body 2 after acid-base neutralization and heavy metal curing, and fall into the waste bin 351 through the exhaust pipe 35, and the treated flue gas will be filtered by the second filter plate 323 in the second slot 322 and enter the output box 41. At this time, the second motor 421 is started, and the second motor 421 drives the multiple fan blades 422 to rotate, generating airflow, increasing or slowing down the flow rate of the flue gas, thereby speeding up or slowing down the speed at which the flue gas is discharged through the output pipe 43.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
