Abstract
Description
Technical Field
[0001] The utility model relates to the field of flue gas treatment equipment, in particular to an integrated denitration and dust removal device for low-temperature flue gas of a glass kiln. Background Art
[0002] A glass kiln is a high-temperature furnace used to melt raw materials and produce various glass products. It is one of the most critical equipment in the glass manufacturing process. Its operation has a direct impact on the output, quality and production cost of the glass. After the glass kiln is calcined, when the internal temperature drops to a certain level, the flue gas will be discharged into the integrated flue gas denitrification and dust removal equipment.
[0003] The existing integrated denitrification and dust removal equipment is basically composed of a frame, a pipeline, a desulfurization component and a filter. The low-temperature flue gas enters the frame through the pipeline, and then the desulfurization component sprays out the desulfurizer to mix the desulfurizer with the flue gas and desulfurize the mixed flue gas. Then the desulfurized flue gas passes through the filter again to complete the dust removal process, and then the flue gas can be discharged from the frame. In order to improve the mixing effect of the desulfurizer and the flue gas, some businesses set a stirring mechanism inside the frame to stir the mixed flue gas and the desulfurizer to improve the mixing efficiency and desulfurization effect. However, the addition of a stirring mechanism increases the cost of the equipment, increases the operating cost of the enterprise to a certain extent, and reduces the competitiveness of the enterprise in the market to a certain extent.
[0004] Therefore, it is necessary to provide a new integrated equipment for denitrification and dust removal of low-temperature flue gas in a glass kiln to solve the above-mentioned technical problems. Utility Model Content

[0007] The flow guiding mechanism includes a pipeline, a dividing plate for dividing the pipeline into a first chamber and a second chamber is fixedly provided inside the pipeline, a blocking plate is fixedly provided on the top of the dividing plate, two flow grooves are provided on the top of the blocking plate, two square frames are fixedly provided on the top of the blocking plate, opposite sides of the two square frames are inclined upward toward one side of the dividing plate, and the two square frames are respectively connected to the two flow grooves.

[0013] Compared with the related art, the integrated equipment for denitrification and dust removal of low-temperature flue gas in a glass kiln provided by the utility model has the following beneficial effects:
[0014] The flue gas generated by the low-temperature calcination of glass in a vacuum furnace enters the pipeline and is divided into two streams of flue gas through the dividing plate inside the pipeline and enters the first chamber and the second chamber of the pipeline respectively. When the two streams of flue gas enter the two square frames respectively, the collision frequency between the flue gas molecules increases due to the smaller flow space, and the flow rate of the two streams of flue gas entering the two square frames increases. Because the two square frames are inclined, the flue gas discharged from the two square frames will be staggered. When the two airflows are about to be staggered, the desulfurization mechanism will spray out the desulfurizer, and the two streams of flue gas will be staggered to form a vortex, which will disrupt the original laminar state of the flue gas. The vortex has a stirring effect on the flue gas and the desulfurizer, thereby improving the mixing efficiency of the flue gas and the desulfurizer, and improving the desulfurization effect of the flue gas. There is no need to add a stirring mechanism, which reduces the cost of equipment, reduces the operating cost of the enterprise to a certain extent, and improves the competitiveness of the enterprise in the market to a certain extent.

[0025] The dust removal mechanism includes a frame 11, the bottom of the frame 11 is fixedly connected to the top of the pipeline 2, the bottom edge of the frame 11 is fixedly connected to the top of the vacuum furnace 1, a support plate 12 is fixedly provided inside the frame 11, a plurality of circular grooves 13 are provided at the top of the support plate 12, a plurality of desulfurization parts are fixedly provided at the bottom of the support plate 12, a dust removal part is provided at the top of the support plate 12, the outer surface of the dust removal part is fixedly connected to the inner surface of the frame 11, the dust removal part includes a filter screen 14, the filter screen 14 is provided at the top of the support plate 12, the outer surface of the filter screen 14 is fixedly connected to the inner surface of the frame 11, the desulfurization part includes a storage tank 15, the top of the storage tank 15 is fixedly connected to the bottom of the support plate 12, and an atomizing nozzle 16 is fixedly provided at the bottom of the storage tank 15.
[0026] like Figure 5 The left side of the pipe 2 is the first chamber, and the right side of the pipe 2 is the second chamber. When the two airflows are about to intersect, the storage tank 15 sprays the desulfurizer through the atomizing nozzle 16. The two flue gases and the desulfurizer intersect to form a vortex. The intersecting vortex disrupts the laminar flow state of the flue gas and enhances the mixing and collision between gas molecules, which is equivalent to establishing an efficient stirring mechanism in the flue gas, so that the desulfurizer reacts more fully with the pollutants in the flue gas, accelerates the desulfurization process, and improves the purification effect.
[0027] The working principle of the utility model is as follows: the smoke generated by the low-temperature calcination of glass in the vacuum furnace 1 enters the pipe 2, and is divided into two smoke streams through the dividing plate 3 inside the pipe 2 and enters the first chamber and the second chamber of the pipe 2 respectively. The two smoke streams move to the inside of the two square frames 6 in the first conical groove 8 of the first chamber and the second conical groove 10 of the second chamber respectively. As the space for their flow gradually decreases, the collision frequency between the smoke molecules increases, so that the flow rate of the two smoke streams gradually increases, and the flow rate of the two smoke streams to the inside of the two square frames 6 is accelerated. At the same time, due to the two The square frame 6 is arranged at an angle, and the flue gases discharged from the two square frames 6 will intersect. When the two airflows are about to intersect, the storage tank 15 will spray the desulfurizer through the atomizing nozzle 16. The two flue gases and the desulfurizer intersect to form a vortex, which will disrupt the original laminar flow state of the flue gas. The vortex has a stirring effect on the flue gas and the desulfurizer, thereby improving the mixing efficiency of the flue gas and the desulfurizer, and improving the desulfurization effect of the flue gas. Subsequently, the desulfurized flue gas enters the filter screen 14 through the circular groove 13 of the support plate 12, and the flue gas is discharged from the frame 11 after dust removal through the filter screen 14, thereby completing the desulfurization and dust removal process of the flue gas of the vacuum furnace 1.
