Description

Technical Field

[0002] With the rapid development of economy, the problems brought by limited resources, environmental degradation and population growth are becoming increasingly prominent. It is of vital importance to use limited resources rationally, cleanly and efficiently. Urban domestic waste incineration technology is an efficient treatment technology. Compared with composting and chemical treatment, this technology has the advantages of complete harmlessness, significant volume reduction and high degree of resource utilization. However, due to the limitations of the operating process, secondary pollution is easily caused during the incineration process. Among them, NOx pollutants in the incineration flue gas are the most direct and have a significant impact. This pollutant not only harms human health, but also causes serious secondary pollution to the atmosphere, soil and groundwater. Therefore, when the burning flue gas is discharged, it needs to be processed by a special catalytic denitrification device before it can be discharged. However, when the existing catalytic denitrification reaction device is in use, it is inconvenient for workers to regularly check the quality of the flue gas discharged through the exhaust pipe, which makes it impossible for workers to judge the reaction effect of the catalytic denitrification reaction device on the flue gas. There are limitations in use and there is room for improvement. Utility Model Content

The first functional component includes a mounting frame 5 arranged inside the smoke exhaust pipe 2, a top surface of the smoke exhaust pipe 2 is provided with a through card slot 6 for the mounting frame 5 to penetrate, a filter gauze 7 is symmetrically arranged on the inner side of the mounting frame 5, a fixing plate 8 is symmetrically installed on the inner top surface and the bottom surface of the mounting frame 5, a side surface of the fixing plate 8 and the inner edge of the filter gauze 7 are both provided with a magnetic strip 9, and the surface of the filter gauze 7 and the fixing plate 8 are symmetrically arranged. The surface is magnetically connected by a magnetic strip 9, and a limiting slot 12 is symmetrically provided on the top of the top surface of the installation frame 5. The inner wall of the limiting slot 12 is inclined, and a limiting baffle 10 is symmetrically arranged at the bottom of the opening that passes through the slot 6. A torsion spring 11 is installed between the inner top of the limiting baffle 10 and the adjacent surface of the opening that passes through the slot 6. The surface length of the limiting baffle 10 is greater than the length of the opening that passes through the slot 6, and the surface width of the limiting baffle 10 is half of the width of the opening that passes through the slot 6, which is convenient for workers to regularly check the quality of smoke discharged from the inside of the smoke exhaust pipe 2. Workers can judge the treatment effect of the reaction body 1 on the smoke according to the amount of impurities attached to the surface of the filter gauze 7. It is simple and easy to operate, with improved functionality and good practicality.

[0022] like Figure 4 and Figure 5As shown, a second functional component is arranged on the outside of one end of the smoke inlet pipe 4, and the second functional component includes a rubber hose 13 arranged on the outside of one end of the smoke inlet pipe 4, and a mounting ring groove 18 for installing the rubber hose 13 is provided on the outer surface of one end of the smoke inlet pipe 4, and a fixing pipe 15 is installed on the surface of the rubber hose 13 at equal distances, and the inner surface of the mounting ring groove 18 is provided with mounting sockets 16 for the fixing pipe 15 to penetrate and engage at equal angles, and exhaust holes 17 are opened on one side surface of the fixing pipe 15 at equal distances, and a connecting port 14 is provided on the outer surface of the rubber hose 13, and the exhaust holes 17 are opened in an inclined shape, and one end of the exhaust hole 17 opens toward the inner wall of the smoke inlet pipe 4, which is convenient for cleaning the inner wall of the smoke inlet pipe 4, so that impurities or dust are not easily attached to the inner wall of the smoke inlet pipe 4, thereby avoiding the situation that the pipeline is blocked, and at the same time, it is also convenient to improve the transportation efficiency of the smoke inside the smoke inlet pipe 4, and the practical effect is good.

[0023] The utility model provides a catalytic denitration reaction device, and the specific working principle is as follows: when the first functional component is installed in the early stage of the utility model, one of the filter yarns 7 is first pushed to move to the inside of the installation frame 5, so that the surface at the inner edge of the filter yarn 7 is magnetically connected to the surface of the fixing plate 8 through the magnetic strip 9, and then the above steps are repeated to install another filter yarn 7.
