Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment, and in particular to a regenerative exhaust gas treatment device for removing dioxins from exhaust gas. Background Technology

[0002] Volatile organic compounds (VOCs) refer to organic compounds that participate in atmospheric photochemical reactions, or organic compounds as defined by relevant regulations. Halogen-containing VOCs can produce dioxins during the purification process. Dioxins are a collective term for polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and their homologues.

[0003] Dioxins are persistent, semi-volatile, bioaccumulative, and highly toxic substances, often referred to as "the most toxic substance on Earth." Their toxicity is more than 1000 times that of potassium cyanide and more than 500 times that of strychnine, and they have teratogenic and carcinogenic effects on humans. Dioxins are extremely insoluble in water but readily soluble in fats, making them prone to accumulation in organisms and difficult to eliminate. Dioxins pose a serious threat to human health and environmental safety, therefore, emission reduction and harmless disposal of dioxins are essential.

[0004] The commonly used dioxin treatment technology is catalytic oxidation technology, which uses a catalyst to destroy dioxins in the exhaust gas. The upper and lower layers of the catalyst are equipped with heat storage layers to store heat in the exhaust gas. Finally, the exhaust gas carrying the catalyst enters the combustion chamber for catalytic oxidation, and is completely decomposed into inorganic substances.

[0005] Currently, the heat storage layer and dioxin catalyst layer are typically stacked directly during installation. When the catalyst or heat storage layer loses activity or is damaged, it needs to be replaced. The current replacement operation requires dismantling each dioxin catalyst layer and heat storage layer one by one from top to bottom, which is cumbersome. Furthermore, the activity of each catalyst and heat storage layer is inconsistent; if they are dismantled and reinstalled simultaneously, it will result in resource waste or reduced exhaust gas treatment efficiency. Therefore, a regenerative exhaust gas treatment device that can individually replace each dioxin catalyst layer or heat storage layer to remove dioxins from exhaust gas is needed.

[0040] When this device is in operation, one of the three heat storage chambers is in a heat release state, one is in a heat storage state, and one is in a purging state. Each heat storage chamber has three states: heat release, heat storage, and purging. The three states are switched sequentially in the order of "heat release-heat storage-purging" at regular intervals. The heat storage chamber on the left is heat storage chamber A11, the middle heat storage chamber is heat storage chamber B12, and the right heat storage chamber is heat storage chamber C13. With heat storage chamber A11 in the heat release state, heat storage chamber B12 in the purging state, and heat storage chamber C13 in the heat storage state as the set conditions, the working process of the device is described in stages below.

[0041] S1: The exhaust gas enters the device through the inlet valve 16 of the heat storage chamber A11. At this time, the heat storage chamber A11 is in an exothermic state. The exhaust gas is heated after passing through the first heat storage layer 2, the dioxin catalyst layer 3, and the second heat storage layer 4. Then it enters the combustion chamber 14 for oxidation. The gas after the reaction enters the heat storage chamber C13. At this time, the heat storage chamber C13 is in a heat storage state. After passing through the second heat storage layer 4, the gas temperature drops and the heat is absorbed by the second heat storage layer 4. Then it passes through the dioxin catalyst layer 3, where the dioxins are decomposed. The gas is then cooled again through the first heat storage layer 2 and discharged through the outlet valve 17 of the heat storage chamber C13. At the same time, the purging gas enters the combustion chamber 14 from the bottom of the heat storage chamber B12. At this time, the heat storage chamber B12 is in a purging state and then discharged through the outlet valve 17 of the heat storage chamber C13.

[0042] After a period of time, when the heat storage capacity of the heat storage chamber C13 reaches the design value, the state is switched.

[0043] S2: The exhaust gas enters the device through the inlet valve 16 of the heat storage chamber C13. At this time, the heat storage chamber C13 is in an exothermic state. The exhaust gas is heated after passing through the first heat storage layer 2, the dioxin catalyst layer 3, and the second heat storage layer 4. Then it enters the combustion chamber 14 for oxidation. The gas after the reaction enters the heat storage chamber B12. At this time, the heat storage chamber B12 is in a heat storage state. After passing through the second heat storage layer 4, the gas temperature drops and the heat is absorbed by the second heat storage layer 4. Then it passes through the dioxin catalyst layer 3, where the dioxins are decomposed. Then the gas is cooled again through the first heat storage layer 2 and discharged through the outlet valve 17 of the heat storage chamber B12. At the same time, the purging gas enters the combustion chamber 14 from the bottom of the heat storage chamber A11. At this time, the heat storage chamber A11 is in a purging state and then discharged through the outlet valve 17 of the heat storage chamber B12.

[0044] After a period of time, when the heat storage capacity of the heat storage chamber B12 reaches the design value, the state is switched.

[0045] S3: The exhaust gas enters the device through the inlet valve 16 of the heat storage chamber B12. At this time, the heat storage chamber B12 is in an exothermic state. The exhaust gas is heated after passing through the first heat storage layer 2, the dioxin catalyst layer 3, and the second heat storage layer 4. Then it enters the combustion chamber 14 for oxidation. The gas after the reaction enters the heat storage chamber A11. At this time, the heat storage chamber A11 is in a heat storage state. After passing through the second heat storage layer 4, the gas temperature drops and the heat is absorbed by the second heat storage layer 4. Then it passes through the dioxin catalyst layer 3, where the dioxins are decomposed. Then the gas is cooled again through the first heat storage layer 2 and discharged through the outlet valve 17 of the heat storage chamber A11. At the same time, the purging gas enters the combustion chamber 14 from the bottom of the heat storage chamber C13. At this time, the heat storage chamber C13 is in a purging state and then discharged through the outlet valve 17 of the heat storage chamber A11.

[0046] S4: Repeat steps S1-S3 until the exhaust gas is completely treated.

[0047] The exhaust gas is pressurized when it enters the corresponding intake valve 16, and the pressure is provided by the upstream equipment. It can simultaneously treat dioxins while treating VOCs, improving the efficiency of the exhaust gas treatment.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
