[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] The utility model provides Figure 1-3A deacidification device for waste incineration shown in the figure comprises a deacidification box 1, a partition 2 is fixedly installed on the inner wall of the deacidification box 1, a secondary filter plate 3 is movably installed on the partition 2, a dust removal box 4 is arranged at the lower side of the deacidification box 1, a filter box 5 is arranged in the dust removal box 4, and an air inlet pipe 6 and an air outlet pipe 7 are fixedly connected to the outer walls of the upper and lower sides of the filter box 5. An air outlet 15 is arranged on the top wall of the deacidification box 1. When in use, the gas from the incineration port is connected through the air inlet pipe 6 and enters the filter box 5. The particulate matter or other solid matter in the incineration gas is filtered through the filter plate 8, and the filtered gas is transported to the deacidification box 1 through the lower air outlet pipe 7 after being filtered again through the filter plate 8. The air outlet pipe 7 is located on the lower side of the partition 2. The gas entering the deacidification box 1 will be sprayed by the nozzle 11, and the gas in the deacidification box 1 is fully mixed. The gas flows upward along the ventilation direction, and then passes through the secondary filter plate 3 installed on the partition 2 for the final filtration of the gas. Finally, the gas is discharged from the inside of the deacidification box 1 through the air outlet 15. In addition, The filter box 5 is fixed inside the dust removal box 4 by fixing threads, and a sealing plate is fixedly connected at the ports of the deacidification box 1 and the dust removal box 4 by bolts. An observation window 16 is arranged on the sealing plate. The dust removal box 4 is made of transparent material. When filtering impurities, the actual operating conditions in the dust removal box 4 and the deacidification box 1 can be observed through the observation window 16, and the accumulation of solid impurities filtered by the filter plate 8 in the dust removal box 4 can be observed. After accumulation to a certain extent, the sealing plate can be removed. A sealing plate is arranged in the filter box 5. By removing the sealing plate, solid impurities such as particulate matter accumulated inside the filter box 5 can be cleaned for subsequent use.

[0020] Specifically, the inner wall of the filter box 5 is fixedly connected with a filter plate 8, and the filter plate 8 is arranged parallel to the inner wall of the filter box 5. One end of the air inlet pipe 6 and the air outlet pipe 7 both penetrate the outer wall of one side of the dust removal box 4, and one end of the air outlet pipe 7 extends to the inner wall of the deacidification box 1. The filter plate 8 is "V" shaped, and a dust filter plate 12 is arranged on the filter plate 8. A bayonet 13 is arranged on the dust filter plate 12, and the bayonet 13 is movably connected to the filter plate 8. The dust filter plate 12 is movably installed on the lower side of the filter plate 8. An opening 14 is arranged on the top of the filter plate 8, and the openings 14 are distributed in an arc array on the outer wall of the filter plate 8, and the dust filter plate 12 is located on the lower side of the opening 14. One end of the air inlet pipe 6 is located in the dust removal box 4, and the other end is fixedly connected to the outer wall of the upper side of the filter box 5. When the gas enters the interior of the filter box 5 through the air inlet pipe 6, it first enters the upper side of the filter box 5 and filters the solid impurities in the gas through the filter plate 8, wherein the filter plate 8 is in an inverted "V" shape. When filtering the gas, the V-shaped filter plate 8 passes the gas through the opening 14 set at the V-shaped tip, and the solid impurities accumulate at the V-shaped tip and gradually slide down to the connection with the filter box 5 as the airflow blows. The impurities are uniformly returned to the place where they are placed. The gas after the filter plate 8 will be filtered again through the dust filter plate 12. The gas after the dust filter plate 12 will complete the filtration of solid impurities in the gas and will be transported to the deacidification box 1 along the outlet pipe 7. When the dust filter plate 12 is installed, the bayonet 13 is installed on the filter plate 8 in parallel. Since the bayonet 13 is fixed, the parallel state of the dust filter plate 12 is always maintained during installation. The bayonet 13 is fitted with the outer wall of the filter plate 8 to complete the installation for use.

[0021] Specifically, the inner walls on the opposite sides of the partition 2 and the deacidification box 1 present a "U"-shaped structure with the opening 14 facing downward. The partition 2 is provided with a mounting port 9, and the secondary filter plate 3 is fixedly installed in the mounting port 9.

After the filtered gas is transported to the deacidification box 1 through the air outlet pipe 7, it will be transported upward. At the same time, liquid will be transported through the water pipe 10 arranged on the outer wall of the lower side of the partition 2, and sprayed through the nozzle 11 to deacidify the gas. When discharged, the gas is finally filtered through the secondary filter plate 3, and then discharged from the deacidification box 1, wherein the secondary filter plate 3 can be fixed to the inner wall of the mounting port 9 by structures such as bolts or buckles to achieve the purpose of filtering the gas.
