Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to an incinerator used for sludge power generation. Background Art

[0002] After the wastewater of the paper mill is treated, a large amount of sludge will be produced. The sludge contains a large amount of organic matter. Burning it as fuel can generate a large amount of heat energy for power generation.

[0003] Publication No. CN211119388U discloses an environmentally friendly sludge incinerator, a furnace body, the furnace body is provided with a vibration chamber, an incineration chamber and a discharge chamber from top to bottom; a feed hopper is provided on the furnace body, and the outlet of the feed hopper is connected with the vibration chamber; a vibration device is provided on the feed hopper; a circulation device is provided on the furnace body. By providing a circulation device, the toxic gas generated in the incinerator can be mixed with fresh air after treatment and then transported to the incinerator, thereby ensuring the oxygen supply in the incinerator and reducing the content of pollutants discharged into the air. However, the patent still has the following problems in actual use:

[0004] When sludge is burned, a large amount of flue gas will inevitably be produced. The flue gas contains a large number of solid particles, so the existing flue gas usually uses a filter to filter the solid particles. However, the blockage of the filter is usually judged by the color of the exhaust flue gas, so that the filter is often found to be blocked during the combustion process of the incinerator. At this time, when the filter is replaced, a large amount of unfiltered flue gas will directly leak and be absorbed by the staff, affecting the health of the staff. Moreover, since the flue gas is a high-temperature gas, it may even cause burns to the staff.

[0005] An incinerator for sludge power generation is proposed to solve the above problems. Utility Model Content

[0036] Working principle: Before using this incinerator for sludge power generation, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, first, the engaging block 212 is toggled to make the spring rod 211 contract, so that the engaging block 212 is disengaged from the engaging groove 213. At this time, the rotating knob 207 makes the positioning dial 209 and the rotating bracket 202 rotate synchronously until the other engaging groove 213 can engage with the engaging block 212. During this process, the filter cover plate 204 located directly above the smoke outlet 101 will rotate with the rotating bracket 202 and move away from the smoke outlet 101, and another clean filter cover plate 204 will move to directly above the smoke outlet 101, thereby avoiding the direct discharge of unfiltered high-temperature flue gas when replacing the filter, affecting the environmental quality and the health of the staff, and also avoiding the high-temperature flue gas from contacting the staff and causing burns, and there is no need to stop the machine when replacing the filter, thereby improving the incineration efficiency;

[0037] When it is necessary to remove the blocked filter, the blocking plate 206 can be removed, and the stopper block 303 can be pushed to both sides to make the slide bar 304 slide with the mounting plate 302. When the first magnet 305 and the second magnet 307 are in contact and magnetically attached, the stopper block 303 and the limiter block 301 are separated from the overlap. At this time, the filter can be taken out together with the filter cover plate 204. At the same time as the filter cover plate 204 is replaced, the clamping installation method is relatively fixed by bolts, which greatly simplifies the disassembly and assembly process, is easy to operate, and saves time and effort.

[0038] After being drawn into the spiral tube 217 by the fan 219 through the air duct 205, the high-temperature hot air from the incinerator will heat the liquid in the water tank 216, so that the heat of the high-temperature hot air can be recycled and utilized, and the temperature rise of the external environment when the heat is removed can be reduced.
