Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a device for the synergistic decomposition of pollutants by ozone in an incinerator. Background Technology

[0002] Waste-derived fuel incineration is widely used due to its advantages such as high calorific value and high recycling rate. However, the flue gas produced during the incineration process still contains many harmful substances, which may cause secondary pollution to the environment. The main components of harmful substances in the flue gas include fly ash, acidic gases (carbon monoxide, carbon dioxide, sulfur dioxide, sulfur trioxide, nitrogen oxides, hydrogen fluoride, hydrogen chloride, etc.), particulate matter, heavy metals, dioxins, etc.

[0003] Waste gas generated during incineration in incinerators is mostly treated by filtration or spraying. However, the current method of decomposing pollutants with ozone has a short decomposition time between ozone and pollutants in actual use, and ozone is not easy to recycle. Based on this, this application proposes an ozone co-decomposition device for pollutants in incinerators, which can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for the co-decomposition of pollutants by ozone in an incinerator.

[0005] The purpose of this utility model is achieved through the following technical solution: a device for co-decomposing pollutants with ozone in an incinerator, comprising a treatment tank, a fixed plate installed inside the treatment tank, an inner cylinder installed below the fixed plate, a filter cylinder sleeved on the inner cylinder, multiple vent holes on the top surface of the fixed plate, a filter plate placed on the fixed plate, multiple uniformly arrayed one-way valves installed on the inner cylinder, air inlet valves installed on both sides of the lower exterior of the treatment tank, a bottom cover for sealing installed at the bottom of the treatment tank, and a water valve installed below the bottom cover.

[0006] Optionally, a top cover for sealing is installed on the top of the processing tank, and exhaust valves are installed on both sides of the top surface of the top cover.

[0007] Optionally, a straight pipe is installed in the middle of the top cover, extending into the interior of the inner cylinder, and an ozone filling valve is installed at the outer end of the top cover.

[0008] Optionally, the inner cylinder is equipped with a plurality of uniformly arrayed mounting cylinders, and the plurality of one-way valves are respectively installed in the plurality of mounting cylinders.

[0009] Optionally, the bottom surface of the inner cylinder is equipped with a plurality of circumferentially arrayed threaded columns, and a support plate is installed on each of the plurality of threaded columns.

[0010] This utility model has the following advantages:

[0011] This ozone-co-decomposition device for pollutants in an incinerator uses a treatment tank as its main body. A fixed plate is installed inside the treatment tank, and an inner cylinder is installed below it. Multiple vents are provided on the fixed plate. A filter cartridge is fitted around the outer side of the inner cylinder, and filter plates are placed on the fixed plate. Multiple one-way valves are installed on the inner cylinder. During operation, waste gas is introduced into the treatment tank from below. The waste gas is filtered through the filter cartridge, and ozone is introduced into the inner cylinder. The ozone decomposes the waste gas within the filter cartridge. After decomposition, the gas enters the filter plates for secondary filtration before being discharged. The entire device performs two gas filtrations and completes decomposition with the participation of ozone, meeting emission requirements.

[0012] At the same time, a reaction liquid can be poured into the inside of the treatment tank so that the waste gas can react with the reaction liquid after entering the treatment tank, which is used for pretreatment of the waste gas. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0019] like Figures 1 to 4 As shown, an ozone co-decomposition device for pollutants in an incinerator includes a treatment tank 1. A fixed plate 12 is installed inside the treatment tank 1, and an inner cylinder 14 is installed below it. A filter cylinder 7 is installed outside the inner cylinder 14. Multiple vent holes 13 are opened on the top surface of the fixed plate 12. A filter plate 8 is placed on the fixed plate 12. Multiple uniformly arrayed one-way valves 10 are installed on the inner cylinder 14. Air inlet valves 5 are installed on both sides of the lower part of the treatment tank 1. A bottom cover 9 for sealing is installed at the bottom of the treatment tank 1. A water valve 6 is installed below the bottom cover 9.

[0020] As an optional technical solution of this utility model, a top cover 2 for sealing is installed on the top of the treatment tank 1, and exhaust valves 3 are installed on both sides of the top surface of the top cover 2. This facilitates the discharge of gas inside the tank from the exhaust valves 3, so as to facilitate the further processing of the gas.

[0021] As an optional technical solution of this utility model, a straight pipe is installed in the middle of the upper cover 2, which extends into the inner cylinder 14. An ozone filling valve 4 is installed at the outer end of the upper cover 2, so that the staff can directly fill the inner cylinder 14 with ozone, so that the ozone reacts with the waste gas in the filter cartridge 7.

[0022] As an optional technical solution of this utility model, multiple uniformly arrayed mounting cylinders 15 are installed on the inner cylinder 14, and multiple one-way valves 10 are respectively installed in the multiple mounting cylinders 15. This facilitates the installation of the one-way valves 10. During installation, it is necessary to ensure that the one-way valves 10 are in the correct direction.

[0023] As an optional technical solution of this utility model, the bottom surface of the inner cylinder 14 is equipped with a plurality of circumferentially arrayed threaded columns 16, and a support plate 11 is installed on each of the plurality of threaded columns 16. The support plate 11 can support the filter cartridge 7 to prevent it from falling off, and facilitate the installation, disassembly and replacement of the filter cartridge 7.

[0024] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: The treatment tank 1 serves as the main body of the device. A fixing plate 12 is installed inside the treatment tank 1, and an inner cylinder 14 is installed below it. Multiple ventilation holes 13 are provided on the fixing plate 12. A filter cylinder 7 is fitted around the outer side of the inner cylinder 14, and a filter plate 8 is placed on the fixing plate 12. Multiple one-way valves 10 are installed on the inner cylinder 14. During use, waste gas is introduced into the treatment tank 1 from below. The waste gas is filtered through the filter cylinder 7. Ozone is then introduced into the inner cylinder 14, where it decomposes with the waste gas. After decomposition, the gas enters the filter plate 8 for secondary filtration before being discharged. The entire device performs two gas filtrations and can complete the decomposition with the participation of ozone, meeting emission requirements. A reaction liquid can also be poured into the treatment tank 1 so that the waste gas reacts with the reaction liquid after entering the treatment tank 1, thus pre-treating the waste gas.
