Description

Technical Field

[0001] The present application relates to the technical field of thermal storage oxidation furnaces, and in particular to an electrically heated thermal storage oxidation furnace with dynamic control of thermal balance. Background Art

[0002] ROT furnace, namely regenerative thermal oxidation furnace, also known as regenerative thermal incinerator, is a high-efficiency waste gas treatment equipment used to treat volatile organic compounds (VOCs). Electric heating regenerative thermal oxidation furnace (RTO-E) is a special regenerative thermal oxidation furnace that uses electric heating to treat VOCs waste gas. Its principle is to heat VOCs waste gas to oxidize and decompose organic matter in VOCs waste gas into carbon dioxide and water, thereby achieving the purpose of purifying VOCs waste gas.

[0003] In the related art, the electrically heated thermal storage oxidation furnace generally includes a furnace body, a lifting valve, a thermal storage layer and a reaction layer. The furnace body is provided with an air inlet and an exhaust port. The thermal storage layer and the reaction layer are both installed in the furnace body. The reaction layer is located in the middle of the furnace body. There are two groups of thermal storage layers, and the two groups of thermal storage layers are located on the top and bottom sides of the reaction layer, respectively. An electric heating wire is installed in the reaction layer. VOCs waste gas enters the furnace body from the air inlet, and the lifting valve can switch the flow path of VOCs waste gas. In the first stage, the lifting valve allows the VOCs waste gas to pass through the thermal storage layer on the top side first, and the thermal storage layer on the top side preheats the VOCs waste gas. The preheated VOCs waste gas enters the reaction layer, and the electric heating wire heats the reaction layer, so that the VOCs waste gas undergoes an oxidation reaction in the reaction layer, and then the VOCs waste gas passes through the thermal storage layer on the bottom side and is discharged from the exhaust port. The VOCs waste gas causes the thermal storage layer on the bottom side to heat up and store heat. In the second stage, the lifting valve allows the VOCs waste gas to pass through the heat storage layer on the bottom side first, and the heat storage layer on the bottom side preheats the VOCs waste gas. The preheated VOCs waste gas undergoes an oxidation reaction in the reaction layer, and then the VOCs waste gas passes through the heat storage layer on the top side and is discharged from the exhaust port. The VOCs waste gas causes the heat storage layer on the top side to heat up and store heat. The first and second stages form a complete working cycle, which can continuously treat VOCs waste gas.

[0004] The electric heating wire in the reaction layer of the electric heating thermal storage oxidation furnace adopts an overall heating control solution. During operation, the VOCs waste gas passes through the thermal storage layer for preheating and enters the reaction layer for oxidation reaction. However, when the VOCs waste gas passes through the thermal storage layer, there are different flow rates in different areas, that is, the VOCs waste gas does not pass through the thermal storage layer evenly, which will cause the thermal storage layer in the area with a large flow of VOCs waste gas to lose heat too quickly, and it is impossible to preheat the subsequent VOCs waste gas. The part of the VOCs waste gas that cannot be preheated in advance reaches the reaction layer. When the oxidation reaction time remains unchanged, the VOCs waste gas is discharged from the reaction layer before it is completely reacted, resulting in a decrease in the oxidation reaction efficiency of the equipment. For areas with low VOCs waste gas flow in the thermal storage layer, the VOCs waste gas temperature will exceed the preheating temperature and enter the reaction layer. When the electric heating wire uniformly supplies heat to the reaction layer, the heat consumption of the reaction layer in this area is reduced. Over time, the temperature of the reaction layer in this area will gradually increase, and the electric heating wire in the area will be at risk of melting. Due to the uneven fluid field of VOCs exhaust gas, the thermal field balance of the reaction layer will be broken, which will lead to a decrease in the oxidation reaction efficiency of the equipment and even damage the equipment. Summary of the invention

[0005] In order to improve the situation where the thermal field balance of the reaction layer is broken, the present application provides an electrically heated thermal storage oxidation furnace with dynamic control of thermal balance.
