AI Technical Summary
When inspecting and repairing existing flue gas ducts, the valves need to be closed, resulting in low efficiency in sealing the ducts and wasting time and effort.
Introducing test air intake and exhaust ducts into the parallel duct fan system and installing test air intake and exhaust valves respectively allows the fan to be inspected and tested without shutting down the machine.
The fan can resume normal operation immediately after maintenance, avoiding work stagnation, improving work efficiency, and saving time and manpower.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of flue gas duct testing devices, and in particular to a closed duct parallel fan system that is convenient for testing. Background Art
[0002] In the related art, the flue gas duct adopts parallel ducts, on which fans are installed, and valves are installed on the ducts at both ends of the fans. When one of the fans has a problem, it needs to be repaired. During the repair, the valves at both ends need to be closed. After the repair is completed, the valve of the other channel is closed, and the valves at both ends of the repair fan are opened to test the repair fan to detect whether it is operating normally. This repair and test method seriously affects the working efficiency of the sealed duct and is time-consuming and labor-intensive. Utility Model Content

[0012] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.
[0013] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0014] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
[0015] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
[0016] In response to the above problems, an embodiment of the present application provides a closed duct parallel fan system that is easy to test.
