Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically a multi-tube dynamic secondary combustion chamber. Background Art

[0002] Treating harmful gases in emissions is the step most closely related to environmental protection. The gases enter an internally heated converter for combustion and are then discharged after further treatment.

[0003] The shortcomings of existing technology:

[0004] Currently, when processing harmful gases, internally heated converters need to be connected to a secondary processor for adequate treatment. However, some temperature is lost during the transmission process, and the gas needs to be reheated to over 850 degrees Celsius before entering the secondary processor, which increases energy costs and occupies too much space. Utility Model Content

[0005] The purpose of this invention is to provide a multi-tube dynamic secondary combustion chamber to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-tube dynamic secondary combustion chamber, comprising an internally heated converter and a discharge furnace head, wherein the internally heated converter is connected to the discharge furnace head via a processing assembly, the processing assembly comprising:

[0007] A multi-tube treatment flue, comprising several tubes, is installed in the internally heated converter;

[0008] A central heating pipe is located at the center of the multi-tube treatment flue and connected to the internal heating converter.

[0009] Preferably, the multi-tube treatment flue is connected to the internally heated converter by a fixed connecting bracket.

[0010] Preferably, the central heating pipe is equipped with a heating wire or is heated by natural gas.

[0011] Preferably, the multi-tube treatment flue is provided with an external insulation layer.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This multi-tube dynamic secondary combustion chamber incorporates a processing assembly comprising a multi-tube treatment flue and a central heating pipe. The multi-tube treatment flue is connected to an internally heated converter via a fixed connecting bracket. The central heating pipe is installed inside the multi-tube treatment flue and connected to the internally heated converter. The rotation of the internally heated converter drives the multi-tube treatment flue to rotate. Heating wires are installed inside the central heating pipe, or natural gas is introduced to provide a heat source, thereby heating both the central heating pipe and the multi-tube treatment flue. The temperature of the multi-tube treatment flue is heated to above 850°C, allowing the gas to be treated to effectively process CO through the multi-tube treatment flue and the central heating pipe. Compared to the internally heated converter connected to a secondary processor, where the gas temperature drops to 500°C or higher during transmission and needs to be reheated upon re-entering the secondary processor, increasing energy consumption, this device reduces energy consumption, lowers costs, and reduces the footprint by integrating the multi-tube treatment flue and the central heating pipe into a single unit.

[0021] Example

[0022] Please see Figure 1-2 As shown, this utility model provides a multi-tube dynamic secondary combustion chamber technical solution, including an internally heated converter 110 and a discharge furnace head 120. The internally heated converter 110 is connected to the discharge furnace head 120 via a processing component. The processing component includes a multi-tube treatment flue 130 and a central heating pipe 140. The multi-tube treatment flue 130 is composed of several tubes 131 surrounding the central heating pipe 140. The multi-tube treatment flue 130 is connected to the internally heated converter 110 via a fixed connecting bracket 150. The central heating pipe 140 is installed inside the multi-tube treatment flue 130 and connected to the internally heated converter 110. The rotation of the internally heated converter 110 drives the multi-tube treatment flue 130 to rotate. During the rotation of the multi-tube treatment flue 130, it not only increases the contact area with the gas to effectively treat CO, but also effectively prevents blockages from accumulating in the multi-tube treatment flue 130. The gas to be treated enters the internally heated converter... The internal temperature of the internally heated converter 110 reaches 600-750℃. Heating wires 160 are installed inside the central heating pipe 140, or natural gas is introduced to provide a heat source, thereby heating the central heating pipe 140 and the multi-tube treatment flue 130. The temperature of the central heating pipe 140 can rise to 1100℃, while the temperature of the multi-tube treatment flue 130 is heated to above 850℃. Thus, the gas to be processed can effectively process CO through the multi-tube treatment flue 130 and the central heating pipe 140. Finally, the gas is sent out from the discharge head 120. Compared to the internally heated converter 110 connected to a secondary processor, where the gas temperature drops to 500℃ or even higher during transmission and needs to be reheated when re-entering the secondary processor, increasing energy consumption, this device reduces energy consumption and lowers costs by integrating the multi-tube treatment flue 130 and the central heating pipe 140 into one unit.

[0023] Furthermore, an insulation layer 132 is installed on the outside of the multi-tube treatment flue 130 to reduce heat loss. The outermost temperature of the multi-tube treatment flue 130 can also reach 850 degrees Celsius, effectively removing CO.

[0024] The working principle of this utility model is as follows:

[0025] In this embodiment, a multi-tube dynamic secondary combustion chamber is used by a processing component, which includes a multi-tube treatment flue 130 and a central heating pipe 140. The gas to be processed enters an internally heated converter 110, where the internal temperature reaches 600-750°C. The central heating pipe 140 and the multi-tube treatment flue 130 are heated by installing a heating wire 160 inside the central heating pipe 140 or by introducing natural gas as a heat source. The temperature of the central heating pipe 140 can rise to 1100°C, and the temperature of the multi-tube treatment flue 130 can be heated to greater than 850°C. Thus, the gas to be processed can effectively process CO through the multi-tube treatment flue 130 and the central heating pipe 140. Finally, the gas is sent out from the discharge head 120.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
