Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to an exhaust gas treatment device with a preheating channel. Background Technology

[0002] Because exhaust gas contains a large amount of heat energy, heat exchange modules are installed in exhaust gas treatment equipment to improve its heat energy recovery and utilization rate. Traditional heat exchange modules mainly rely on heat exchange fluid for heat energy recovery and transfer. During the transfer process, heat energy loss is easily caused. Moreover, heat exchange occurs again during secondary utilization, resulting in heat loss during the exchange process. This means the heat cannot be directly applied to the equipment being heated, leading to low conversion efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is that traditional heat exchange modules have large heat loss, resulting in low conversion efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a tail gas treatment device with a preheating channel, including a vertical purification tower, a horizontal support frame fixedly assembled inside the vertical purification tower, a horizontal preheating channel pipe fixedly assembled inside the horizontal support frame, an upper heat insulation plate fixedly assembled at the upper end of the horizontal support frame, a detachable metal filter screen fixedly assembled at the upper end of the horizontal support frame on one side of the upper heat insulation plate, a bottom positioning groove that cooperates with the horizontal support frame is opened on the lower surface of the horizontal preheating channel pipe, and an external air inlet pipe is fixedly assembled on the side wall of the vertical purification tower away from the detachable metal filter screen.

[0005] The vertical purification tower is internally equipped with a horizontally placed spray module.

[0006] The exhaust gas channel, which forms a U-shaped structure, is located inside the horizontal support frame and outside the horizontal preheating channel pipe.

[0007] The vertical purification tower has a lateral maintenance port on the side wall near the detachable metal filter screen, and a lateral sealing cover is fixedly installed inside the lateral maintenance port.

[0008] The vertical purification tower has staggered inclined guide plates fixedly mounted on its upper surface at the top of the horizontal support frame.

[0009] The inclined guide plate is fixedly fitted with a bottom return pipe that is connected to the bottom return water tank.

[0010] The beneficial effects of this utility model are:

[0011] (1) The exhaust gas treatment device with a preheating channel of this utility model is formed by fixing a horizontal support frame inside the vertical purification tower, fixing a horizontal preheating channel pipe in the horizontal support frame, forming a U-shaped exhaust gas channel around the horizontal preheating channel pipe, so that the heat energy is directly applied to the workpiece to be heated, which greatly improves the heat recovery efficiency.

[0012] (2) By fixing and assembling the upper heat insulation plate on the upper end of the horizontal support frame, closing the upper opening near the external air inlet pipe, and setting a detachable metal filter screen on the other side opening, the exhaust gas can be pre-filtered, improving the internal treatment effect and facilitating later maintenance.

[0013] (3) A staggered inclined guide plate is fixedly installed on the upper surface of the vertical purification tower at the upper end of the horizontal support frame. This not only prevents the spray water from flowing into the tail gas channel of the U-shaped structure, but also increases the internal processing stroke and facilitates the return of the spray liquid. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 This is a schematic diagram of the internal structure of this utility model. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Figure 1 and Figure 2The exhaust gas treatment device with a preheating channel shown includes a vertical purification tower 1. A horizontal support frame 2 is fixedly installed inside the vertical purification tower 1. A horizontal preheating channel pipe 3 is fixedly installed inside the horizontal support frame 2. An upper heat insulation plate 4 is fixedly installed at the upper end of the horizontal support frame 2. A detachable metal filter screen 5 is fixedly installed on the upper end of the horizontal support frame 2 on one side of the upper heat insulation plate 4. A bottom positioning groove that cooperates with the horizontal support frame 2 is opened on the lower surface of the horizontal preheating channel pipe 3. An external air inlet pipe 6 is fixedly installed on the side wall of the vertical purification tower 1 away from the detachable metal filter screen 5.

[0020] The removable metal filter screen 5 has a zeolite molecular sieve fixed inside for adsorption, which is used to efficiently adsorb impurities in the exhaust gas.

[0021] To coordinate with the upper cold water spray, the vertical purification tower 1 is internally equipped with a horizontal spray module 7.

[0022] The horizontal spray module 7 consists of a horizontal guide pipe fixed inside the vertical purification tower 1 and a high-pressure nozzle fixed at the lower end of the horizontal guide pipe.

[0023] To improve heat conduction and area, a U-shaped exhaust gas channel is formed inside the horizontal support frame 2, located outside the horizontal preheating channel pipe 3.

[0024] The external air intake pipe 6 guides the high-temperature exhaust gas into the vertical purification tower 1, directing it from one end of the U-shaped exhaust gas channel to the other side of the U-shaped exhaust gas channel. Finally, it passes through the detachable metal filter screen 5 for solid adsorption and separation, and then is introduced upward into the interior of the vertical purification tower 1.

[0025] To facilitate lateral maintenance, a lateral maintenance port is provided on the side wall of the vertical purification tower 1 near the removable metal filter screen 5, and a lateral sealing cover plate 8 is fixedly installed inside the lateral maintenance port.

[0026] The side sealing cover 8 is fixed to the outer opening of the side maintenance port by bolts, thereby closing the side maintenance port.

[0027] To accommodate the inclined placement and material guiding, the upper surface of the vertical purification tower 1 is fixedly fitted with staggered inclined material guiding plates 9 located at the upper end of the horizontal support frame 2.

[0028] In order to facilitate the recycling of the spray liquid, a bottom return pipe 10 is fixedly installed on the lower surface of the inclined guide plate 9 and is connected to the bottom return water tank.

[0029] The bottom-mounted return water tank uses its internal pump to draw the internal spray liquid into the horizontal spray module 7. Then, the horizontal spray module 7 sprays the high-pressure spray liquid into the vertical purification tower 1 to cool and mix the internal exhaust gas. The liquid then falls onto the inclined guide plate 9 and finally flows back into the bottom-mounted return pipe 10.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
