[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0053] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.
[0054] Example 1
[0055] Reference Figure 1 to Figure 3 and Figure 7 , which is the first embodiment of the present invention, provides a catalyst module inspection device in a denitration reactor, which includes a drive unit 100, including a track chassis 101, a protective cover 102 arranged on the top of the track chassis 101, and a fixing column 103 arranged on the inner side of the protective cover 102.
[0056] Preferably, the track chassis 101 is connected to the protective cover 102. The track chassis 101 can make the detection device easily pass over the dusty modules and the triangular seals between the modules, ensuring that the detection can be moved inside the reactor. The protective cover 102 can provide certain protection for the components of the rotating unit 200, thereby ensuring that the radar detection unit 300 can move back and forth.
[0057] The rotating unit 200 includes a connecting piece 201 arranged on the inner side of the protective cover 102, a connecting plate 202 sleeved on the outer side of the fixed column 103, a movable block 203 arranged on the inner wall of the protective cover 102, a sliding column 204 arranged on the inner side of the movable block 203, a first slider 205 arranged on the side wall of the sliding column 204, a first set of rods 207 arranged at one end of the connecting plate 202, a top rod 206 arranged on the inner side of the first set of rods 207, a second set of rods 208 arranged on the inner side of the first set of rods 207, and a limit block 209 arranged on the inner wall of the first set of rods 207; an automatic obstacle avoidance unit 300 is installed on one side of the crawler chassis 101; the second set of rods 208 includes a radar detection unit 400 arranged at its end.
[0058] Preferably, the end of the connecting member 201 passes through the protective cover 102 and extends to the outside thereof; the connecting member 201 is connected to the connecting plate 202, and the rotation of the connecting member 201 can drive the connecting plate 202 to swing continuously along the fan-shaped angle; thereby, the radar detection unit 400 arranged at the end of the second set of rods 208 can be driven to move along the arc angle; further, the detection range of the radar detection unit 400 can be expanded; the movable block 203 is moved in the horizontal direction to drive the sliding column 204 to move in the vertical direction; the movement of the sliding column 204 drives the first slider 205 to move, and the movement of the first slider 205 drives the push rod 206 to move along the trajectory inside the first set of rods 207; under normal conditions, the end of the push rod 206 squeezes two sets of limit blocks 209, and the positions of the first set of rods 207 and the second set of rods 208 can be fixed by the set limit blocks 209; thereby ensuring that the position of the second set of rods 208 will not move arbitrarily during the rotation of the second set of rods 208; and further ensuring that the radar detection unit 400 will not move arbitrarily.
[0059] The radar detection unit 300 transmits the signal reflected by the radar wavelength to the computer device; the height of the catalyst end face is displayed with a color gradient, and the middle color of the gradient can be designated as the normal height. When the radar wave irradiates the catalyst end face, if the catalyst monomer is damaged, the monomer will be displayed on the layer plane as being concave, and the color will be darker or lighter. If there is dust accumulation on the end face, the color will be lighter or darker. If the catalyst end face below cannot be scanned due to dust accumulation on the dust blocking net, the catalyst end face layer will display other colors to indicate that there is dust accumulation above the dust blocking net; when the catalyst end face channel is blocked, the plan view shows that the catalyst channel is in the form of solid small squares, and the unblocked channel is in the form of a square.
[0060] The detection device is placed on the dust blocking net of the catalyst layer of the reactor. The detection device automatically reciprocates and scans the catalyst flat layer according to the set route, automatic obstacle avoidance device and radar wave transmitting and receiving device. When the last module is scanned, the detection device automatically returns along the reactor wall. Since a dust blocking net is provided above the end face of the catalyst, the scanning layer automatically filters out the dust blocking net above the catalyst. If there is dust accumulation above the dust blocking net, the dust accumulation map is automatically added to the catalyst end face plane map.
