Description

Technical Field

[0001] The utility model relates to the technical field of garbage incineration, in particular to a garbage incineration smoke and solid waste treatment device. Background Art

[0002] With the acceleration of urbanization, the amount of domestic waste has increased rapidly. As an efficient and volume-reducing treatment method, waste incineration has played an important role in urban waste treatment. However, there are some problems in the existing waste incineration devices during the incineration process, which not only affect the efficiency and effect of incineration, but also pose potential risks to the environment.

[0003] First, the existing incinerator dumps the garbage into the incinerator during incineration. The garbage in the incinerator will accumulate due to slow burning or too fast dumping. Due to the different shapes, densities and compositions of garbage, it is easy to form uneven accumulation layers when it accumulates in the incinerator, resulting in uneven heat distribution during the incineration process and incomplete incineration of some garbage. This not only affects the efficiency of incineration, but also increases the difficulty of subsequent treatment.

[0004] Secondly, the disposal of incineration waste is also a challenge faced by existing devices. The incineration waste contains a large amount of heavy metals, organic matter and other harmful substances. If not handled properly, it will not only pollute the environment, but also threaten human health. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Please refer to the attached Figure 1-6 The present embodiment is a garbage incineration smoke and solid waste treatment device: it includes a bracket 1, the side of the bracket 1 is fixedly connected to an incinerator 2, the bottom of the incinerator 2 is an inclined structure, the upper end of the incinerator 2 is provided with a feed port 3 and a smoke exhaust pipe 4, the lower end of the incinerator 2 is provided with a fan 5 and 2 rows of incinerators, the fan 5 and the 2 rows of incinerators are installed at the bottom of the incinerator 2, a screening plate 7 is provided in the incinerator 2, the screening plate 7 is located obliquely above the 2 rows of incinerators, and a slag outlet 8 is provided on the incinerator 2 below the screening plate 7, and a collecting box 9 is provided at the slag outlet 8.

[0025] The matching part of the bracket 1 and the incinerator 2 is an inclined support rod, the bottom surface of the incinerator 2 and the inclined support rod of the bracket 1, the lower half of the incinerator 2 is a triangular prism structure, the smoke exhaust pipe 4 is vertically placed above the incinerator 2, and a flue gas purifier is provided on the smoke exhaust pipe 4. The smoke purifier can filter the soot and process the exhausted flue gas at the same time to avoid air pollution caused by flue gas emission. The smoke exhaust pipe 4 is a straight exhaust type, and the smoke exhaust pipe 4 is vertically placed directly above the incinerator. During combustion, the smoke is affected by the high-temperature hot air below and has an upward force, so that the smoke can be discharged from the smoke exhaust pipe 4 more quickly, ensuring the oxygen concentration in the incinerator 2 and avoiding burning. In the case where the garbage inside the incinerator 2 is not fully burned due to the low oxygen content, the material reduction port is located on the side of the incinerator 2, and the feed port 3 is close to the inclined bottom of the incinerator 2. The garbage to be incinerated enters the incinerator 2 through the feed port 3. The garbage entering the incinerator 2 will first fall on the screening plate 7. The garbage rolls and collides on the screening plate 7, causing the smaller volume of garbage to fall downward, and the larger volume of garbage is retained on the upper side, so as to be stratified in the future. During combustion, the burning flames can have more contact with the surface of the garbage. At the same time, the stratified distribution of garbage also increases the air circulation on the surface of the garbage, avoiding the situation of incomplete combustion caused by garbage accumulation, and improving the efficiency of garbage combustion.

[0026] The screening plate 7 includes a first plate body 701, a second plate body 702 and a third plate body 703. Only one end of the first plate body 701 and the second plate body 702 is fixedly connected to the bottom of the incinerator 2. The first plate body 701 is provided with a first filter slot 704, and the second plate body 702 is provided with a second filter slot 705. One end of the third plate body 703 is fixedly connected to the bottom of the incinerator 2, and the other end of the third plate body 703 is fixedly connected to the side inner wall of the incinerator 2. The third plate body 703 is provided with a third filter slot 706. The widths of the first filter slot 704, the second filter slot 705 and the third filter slot 706 decrease step by step.

[0027] In order to burn garbage of different volumes in layers, the incinerator 2 has a first plate 701, a second plate 702 and a third plate 703 on the inner side. The first plate 701 and the second plate 702 have gaps with the sides of the inner wall of the incinerator 2, and the gap of the first plate 701 is larger than the gap of the second plate 702. The gap and the first filter hole on the front side of the first plate 701 are larger than the gap and the second filter hole on the front side of the second plate 702. Garbage of different volumes can be secondary classified to improve combustion efficiency. After the garbage on the first plate 701 and the second plate 702 is burned to a certain volume, the smaller garbage will fall to the third plate 703 through the first filter hole, the second filter hole or the gap. On the top, the width of the third filter groove 706 on the third plate 703 is the smallest. The garbage can fall from the third filter hole only after it is incinerated into waste slag. The waste slag falling from the third filter hole falls into the collection box 9 from the slag outlet 8, and the burned waste slag is processed to avoid the accumulation of waste slag in the incinerator 2; the incinerator 2 row provides a heat source and a fire source for the incinerator 2, and the incinerator 2 is heated to a higher temperature through the incinerator 2 row, so that the temperature in the incinerator 2 reaches the temperature of garbage self-contamination. Combustion requires temperature and oxygen. In order to ensure that there is enough oxygen supply in the incinerator 2, the fan 5 at the bottom of the incinerator 2 continuously supplies air to the inside of the incinerator 2 to ensure that the garbage in the incinerator 2 has sufficient combustion conditions.

[0028] In order to prevent garbage from piling up on the longest layer of the screening plate 7, the first plate body 701 and the second plate body 702 on the screening plate 7 are tilted, and the surfaces of the first plate body 701 and the second plate body 702 are smooth. The garbage on the first plate body 701 and the second plate body 702 receive the kinetic energy of falling and the traction of its own gravity component, ensuring that the garbage has a tendency to fall downward, ensuring that the garbage on the first plate body 701 can fall onto the second plate body 702 as long as it is smaller than the first filter trough 704. The above description is also applicable to the second plate body 702, thereby achieving the purpose of stratifying the garbage in the incinerator 2 and improving the efficiency of garbage combustion in the incinerator 2.

[0029] The air supply holes and the 2 rows of incinerators are both located at the bottom of the incinerator 2. The bottom of the incinerator 2 is an inclined surface, which can facilitate the collection and sorting of waste residues on the one hand, and increase the contact area between the 2 rows of incinerators and the garbage in the incinerator 2 on the other hand, thereby improving the incineration degree of the garbage in the incinerator 2.

[0030] One end of the feed pipe 10 is connected to the feed port 3, and the other end is connected to the feed funnel 11. The feed funnel 11 is placed vertically. The feed funnel 11 has a large upper and small lower structure, which is convenient for stacking garbage inside. Furthermore, a crusher can also be installed at the feed funnel 11. The crusher can be used to crush the garbage so that the garbage entering the incinerator 2 is arranged in a relatively fluffy and small manner, which is convenient for subsequent incineration work.

[0031] The connecting block 12 is located on the outside of the slag outlet 8, and the burned waste slag falls into the collection box 9 through the connected channel. The drop hole 13 at the upper end of the collection box 9 just matches the channel of the connecting block 12. The normally falling waste slag is relatively loose when stacked. In order to reduce the volume of the waste slag and facilitate subsequent processing, a pressing plate 15 is installed on the side of the collection box 9. The outside of the pressing plate 15 is equipped with a telescopic rod 16. The telescopic rod 16 is a hydraulic telescopic rod 16. The pressing plate 15 can move left and right under the control of the telescopic rod 16 to collect the waste slag. The box 9 and the telescopic rod 16 are both fixedly mounted on the bracket 1. When the telescopic rod 16 pushes the pressing plate 15 to move to the right, the pressing plate 15 collects the waste slag in the box 9 and squeezes it to compress the overall volume of the waste slag. When the pressing plate 15 is compressed, in order to prevent the waste slag from falling from the rear side of the pressing plate 15, a cover plate 14 is provided at the drop hole 13. When the waste slag is compressed, the newly fallen waste slag is retained in the connecting block 12. After the pressing plate 15 is reset, the cover plate 14 is opened, and the waste slag in the connecting block 12 falls into the collection box 9 under the action of its own weight.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
