Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, and more specifically, to a dioxin degradation processor for waste incineration fly ash. Background Technology

[0002] With the acceleration of urbanization, waste incineration has been widely used as an efficient and volume-reducing waste treatment method. However, the incineration process generates a large amount of fly ash, which may contain toxic and harmful substances such as dioxins. Dioxins are a class of highly toxic organic compounds, and their generation is mainly related to the combustion of chlorinated materials such as chlorinated plastics and electronic waste. During waste incineration, if the combustion temperature is not properly controlled or combustion is incomplete, dioxins are easily generated. Dioxins are persistent, bioaccumulative, and highly toxic, posing a serious threat to humans and the ecological environment. Therefore, the development of efficient dioxin degradation processors for waste incineration fly ash is particularly important.

[0003] A search revealed a Chinese patent with publication number CN215506346U, which discloses a dioxin degradation processor structure for waste incineration fly ash. The structure includes an outer shell, a baffle plate at the inlet of the outer shell (one end connected to the outer shell, the other end forming a flow channel with the inner wall of the outer shell), an activated carbon adsorption layer on the surface of the baffle plate, several wavy diversion plates on the rear side of the baffle plate, both sides of the diversion plates coated with a titanium dioxide layer, a ring-shaped ultraviolet lamp on the inner wall of the outer shell located at the diversion plate, and a zigzag polyimide fiber mesh at the outlet of the outer shell. This design features an extended treatment path, improved treatment adequacy, and enhanced treatment effect.

[0004] Although the dioxin degradation processor for waste incineration fly ash designed above can achieve the degradation of dioxins in waste incineration fly ash during use, in actual use, due to the structural design, the adsorption capacity of the activated carbon adsorption layer on the surface of the baffle plate will decrease after long-term use, and the designed disassembly structure is located inside the processor and cannot be directly removed from the outside, which means that the operation needs to be stopped when cleaning or replacing. At the same time, after long-term use inside the outer casing, the surface of the ultraviolet lamp will be covered with dust, affecting the light effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dioxin degradation processor for waste incineration fly ash.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dioxin degradation processor for waste incineration fly ash, comprising a processor housing. One end of the processor housing has two inner walls at the inlet of the waste incineration fly ash fixedly provided with guide blocks, and the other end of the processor housing has an inner wall at the outlet side fitted with a polyimide fiber mesh. Inside the processor housing, near the rear side of the guide blocks, a first adsorption component and a second adsorption component are sequentially inserted. Two contact plates are provided between the second adsorption component, the first adsorption component, and the polyimide fiber mesh. The end of each contact plate extends to the outside of the processor housing and is fixedly connected to a second fixing plate. Lighting components are installed on the outer sides of the two outer walls of the processor housing outside the contact plates, and a lighting component is also installed in the middle of the processor housing between two adjacent contact plates.

[0007] As a further improvement to the technical solution of this utility model, the first adsorption component and the second adsorption component have the same structure, and both the first adsorption component and the second adsorption component include a third fixing plate fixedly connected to the outer wall of the processor housing. One end of the third fixing plate is fixedly connected to a first vertical plate inserted into the inside of the processor housing, and the other end of the third fixing plate is connected to a second vertical plate. The inner sidewall of the first vertical plate is located inside the second vertical plate and is fixedly connected to a plurality of staggered V-shaped plates.

[0008] As a further improvement to the technical solution of this utility model, the outer surface of the V-shaped plate is provided with an activated carbon layer, and there is no connection between the V-shaped plate and the second vertical plate.

[0009] As a further improvement to the technical solution of this utility model, locking bolts are connected between the four corners of the third fixing plate and the outer wall of the processor housing, and the four corners of the third fixing plate are provided with connecting holes for the third fixing plate to pass through. The outer wall of the processor housing is provided with internal threaded holes at the connection points of the locking bolts.

[0010] As a further improvement to the technical solution of this utility model, a handle is provided on the outer wall of the middle part of the third fixing plate, a T-shaped card block is provided at the end of the second vertical plate to be inserted into the third fixing plate, and a T-shaped card groove is provided at the bottom of the third fixing plate corresponding to the outside of the T-shaped card block.

[0011] As a further improvement to the technical solution of this utility model, the contact plate is welded and fixed to the second fixing plate, the second fixing plate is fixedly connected to the outer wall of the processor housing by bolts, and the outer surface of the contact plate is provided with a titanium dioxide layer.

[0012] As a further improvement to the technical solution of this utility model, the illumination component includes a first fixing plate fixedly connected to the outer wall of the processor housing, and a lamp mounting base inserted into the interior of the processor housing is fixedly connected to the inner side wall of the first fixing plate, and a plurality of ultraviolet lamps are installed on the lamp mounting base.

[0013] The beneficial effects of this utility model are: 1. By setting up an adsorption component, the fly ash from waste incineration can be guided and adsorbed after entering the casing of the dioxin degradation processor. Multiple staggered V-shaped plates provide guidance and increase the contact area. An activated carbon layer is set on the outer surface of the V-shaped plates, which further increases the contact area between the activated carbon layer and the fly ash, thereby improving the adsorption effect of harmful substances. The adsorption component is easy to install and remove from the processor casing. After the adsorption component is removed, the second vertical plate can be removed, which makes it convenient for the operator to clean the surface of the V-shaped plate or recoat the activated carbon layer to achieve a stable adsorption effect. 2. The contact plate facilitates further diversion of incoming fly ash. After the entire contact plate is fixed to the second fixing plate, it is convenient for the user to remove the second fixing plate and take the contact plate out of the processor housing for cleaning. The titanium dioxide layer can also be recoated. The light-emitting component is easy to install and remove from the processor housing, which facilitates the cleaning of dust adhering to the surface of the ultraviolet lamp. The hydroxyl radicals generated by the ultraviolet lamp irradiation of the titanium dioxide layer fully contact the fly ash to photodegrade dioxins, improving the degradation efficiency. The dual adsorption component, two sets of contact plates, and light-emitting component can be removed individually when cleaning is required, without affecting the normal use of the processor.
