Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas recovery technology, and in particular to a flue gas preheating, recovery and reuse device. Background Technology
[0002] The flue gas preheating recovery and reuse device includes multiple processes for recovering and reusing flue gas. Among them, the filtration mechanism is an important step. The filtration mechanism is located on the right side of the boiler body and is used to filter impurities in the flue gas. When filtering flue gas, a large amount of dust in the flue gas will form dirt inside the equipment. In addition, sulfur dioxide gas in the flue gas is prone to corrosion at low temperatures, forming corrosion products that corrode the inside of the equipment, thereby affecting its service life. Improvements are needed. Utility Model Content
[0003] The purpose of this invention is to provide a flue gas preheating, recovery, and reuse device to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] A flue gas preheating, recovery, and reuse device includes a support frame, a housing fixedly mounted on the support frame, a filter body installed on one side of the housing, a cleaning component inside the housing, a slag discharge port on the lower end face of the housing, a bottom plate sealing the housing installed below the slag discharge port, a fixing plate fixedly mounted on the upper end face of the housing, a connecting plate at the upper end of the fixing plate, a driving component mounted on the connecting plate, a second rotating seat rotatably mounted at the center position of the upper end face of the housing, and a power transmission connecting component between the driving component and the second rotating seat.
[0006] Further configuration: The drive assembly includes a motor fixedly mounted on the upper surface of the connecting plate, and a first rotating seat is fixedly mounted on the output end of the motor.
[0007] Further configuration: The connecting assembly includes a first fixed rod fixedly installed on the first rotating seat, a second fixed rod fixedly installed on the second rotating seat, and connecting rods rotatably installed at the ends of the first fixed rod and the second fixed rod.
[0008] Further configuration: The cleaning component includes a connecting shaft rotatably mounted to the upper end of the housing, the connecting shaft being fixedly connected to the lower end of the second rotating seat, a connecting frame being fixedly mounted on the connecting shaft, and multiple scrapers for cleaning the inner wall of the housing being fixedly mounted between the connecting frames.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a drive component to transmit power to the second rotating seat through the connecting component, the cleaning component moves and realizes semi-circular swing cleaning of the inner wall of the housing. This solves the problem that when the device filters flue gas, a large amount of dust in the flue gas will form dirt inside the equipment, and sulfur dioxide gas in the flue gas is prone to corrosion at low temperatures, forming corrosion products that corrode the inside of the equipment, thus affecting its service life.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] like Figures 1-5 As shown, the system includes a support frame 1, a housing 2 fixedly mounted on the support frame 1, a filter body 3 mounted on one side of the housing 2, a cleaning component inside the housing 2, a slag discharge port 202 on the lower end face of the housing 2, a bottom plate 203 for sealing the housing 2 mounted below the slag discharge port 202, a fixing plate 21 fixedly mounted on the upper end face of the housing 2, a connecting plate 22 on the upper end of the fixing plate 21, a driving component mounted on the connecting plate 22, a second rotating seat 28 rotatably mounted at the center of the upper end face of the housing 2, and a power transmission connecting component between the driving component and the second rotating seat 28.
[0022] In this embodiment: the driving component includes a motor 23 fixedly mounted on the upper surface of the connecting plate 22, a first rotating seat 24 fixedly mounted on the output end of the motor 23, and a connecting component including a first fixed rod 25 fixedly mounted on the first rotating seat 24, a second fixed rod 27 fixedly mounted on the second rotating seat 28, and a connecting rod 26 rotatably mounted at the ends of the first fixed rod 25 and the second fixed rod 27; when the motor 23 is started, it drives the first fixed rod 25 to perform a circular motion, and the movement of the first fixed rod 25 drives the connecting rod 26 to move, thereby driving the second rotating seat 28 to swing semi-circularly.
[0023] In this embodiment, the cleaning component includes a connecting shaft 204 rotatably mounted to the upper end of the housing 2. The connecting shaft 204 is fixedly connected to the lower end of the second rotating seat 28. A connecting frame 205 is fixedly mounted on the connecting shaft 204. Multiple scrapers 206 for cleaning the inner wall of the housing 2 are fixedly mounted between the connecting frames 205.
[0024] The working principle and usage process of this utility model are as follows: When using the device, the flue gas processed in the previous process enters the housing 2. The filter body 3 filters the flue gas and sends it to the next process. After the device has been working for a long time, a large amount of dust in the flue gas will form dirt inside the housing 2 and adhere to the inner wall of the housing 2. The motor 23 is started to drive the first fixed rod 25 to make a circular motion. The movement of the first fixed rod 25 drives the connecting rod 26 to move, which in turn drives the second rotating seat 28 to swing semi-circularly. This causes the scraper 206 to swing and clean the dirt on the inner wall of the housing 2. The bottom plate 203 is opened, and the dirt will be discharged through the slag discharge port 202. This solves the problem that when the device filters flue gas, a large amount of dust in the flue gas will form dirt inside the equipment, and the sulfur dioxide gas in the flue gas is prone to corrosion at low temperatures, forming corrosive substances that corrode the inside of the equipment and thus affect its service life.
[0025] 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 illustrative of the principles of this 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.
