Abstract
Description
Technical Field
[0001] The utility model relates to the field of air guide pipes, in particular to an air guide pipe with a spray structure. Background Art
[0002] During the production process of furfural, a large amount of waste gas is generated. This waste gas mainly comes from the residual waste gas in the hydrolysis kettle after the hydrolysis of the raw materials. This waste gas contains a small amount of product, acetic acid and other light and heavy components. In order not to affect the subsequent hydrolysis and increase the overall output, it can only be discharged. If these waste gases are directly discharged into the atmosphere without effective treatment, they will cause certain pollution to the environment. At present, there are some technologies and methods for the treatment of waste gas from furfural plants. The most commonly used methods are activated carbon adsorption or zeolite plus catalytic combustion waste gas treatment. When treating the waste gas generated in the furfural production process, it is necessary to use an air duct to transport the waste gas from the hydrolysis reactor to the waste gas treatment equipment. In order to reduce the workload of the waste gas treatment equipment, increase the service life of the consumables in the waste gas treatment equipment, and reduce the cost of using the waste gas treatment equipment, a gas duct with a spray structure is needed to pre-treat the waste gas generated in the furfural production process. Utility Model Content
[0003] The main purpose of the utility model is to provide an air guide duct with a spray structure, which can effectively solve the problems in the background technology.

The exhaust gas blocking structure consists of a fixed base column, a rotating base column, an installation shaft and a rotating blade. There are two fixed base columns and they are symmetrically arranged in the upper and lower parts. The rotating base column is rotatably installed between the two fixed base columns. There are two installation shafts and they are respectively fixedly installed at both ends of the rotating base columns, and the installation shafts are simultaneously rotatably installed in the fixed base column. There are a plurality of rotating blades and they are distributed in a ring shape on the outer wall of the rotating base column.
[0006] Preferably, the first end of the third stainless steel tube is fixedly mounted with the second stainless steel tube, and the first stainless steel tube is fixedly mounted with the first stainless steel tube at the first end of the second stainless steel tube.
[0007] Preferably, a plurality of mounting holes are evenly opened on the wall of the third stainless steel tube, and the mounting holes penetrate the wall of the third stainless steel tube inside and outside.
[0008] Preferably, the spray assembly consists of a water delivery pipe and a spray head, and there are several spray heads that are fixedly installed on the water delivery pipe.
[0009] Preferably, the water delivery pipe on the spray assembly is located outside the third stainless steel pipe, and the spray head is fixedly inserted into the installation hole opened on the third stainless steel pipe from the outside to the inside.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] By arranging a spray assembly on the third stainless steel pipe, the spray assembly can spray and cool the waste gas generated in the furfural production process passing through the third stainless steel pipe, thereby reducing the temperature of the waste gas generated in the furfural production process. At this time, part of the waste gas will condense into liquid, thereby realizing pretreatment of the waste gas generated in the furfural production process, and ultimately reducing the workload of subsequent waste gas treatment equipment, increasing the service life of consumables in the waste gas treatment equipment, and reducing the cost of using the waste gas treatment equipment; by arranging a waste gas blocking structure in the third stainless steel pipe, when the waste gas flows through the third stainless steel pipe, the waste gas blocking structure will block the waste gas, and at the same time, when the waste gas flows through, the rotating base column, the mounting shaft and the rotating blades will rotate on the fixed base column, and the rotating rotating blades will disrupt the waste gas flow, thereby achieving the purpose of reducing the waste gas flow rate, and ultimately the waste gas can be fully spray-cooled by the spray assembly, thereby making the spray assembly have a better spray cooling effect on the waste gas.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, an air guide pipe with a spray structure includes a third stainless steel pipe 3, a spray assembly 4 is fixedly installed on the third stainless steel pipe 3, and a plurality of exhaust gas blocking structures 5 are staggeredly installed in the third stainless steel pipe 3. The exhaust gas blocking structure 5 is composed of a fixed base column 9, a rotating base column 11, an installation shaft 12 and a rotating blade 13. There are two fixed base columns 9 and they are symmetrically arranged up and down. The rotating base column 11 is rotatably installed between the two fixed base columns 9. There are two installation shafts 12 and they are fixedly installed at both ends of the rotating base column 11 respectively, and the installation shafts 12 are simultaneously rotatably installed in the fixed base column 9. There are several rotating blades 13 and they are distributed in an annular shape on the outer wall of the rotating base column 11. When in use, the exhaust gas will flow through the third stainless steel pipe 3. At this time, the spray assembly 4 can spray water into the third stainless steel pipe 3, thereby spraying and cooling the exhaust gas flowing through the third stainless steel pipe 3, thereby making the furfural production The waste gas generated during the process is cooled, and part of the waste gas will be condensed into liquid, thereby realizing the pretreatment of the waste gas generated in the furfural production process, and finally reducing the workload of the subsequent waste gas treatment equipment, increasing the service life of the consumables in the waste gas treatment equipment, and reducing the cost of using the waste gas treatment equipment. By arranging a waste gas blocking structure 5 in the third stainless steel pipe 3, the waste gas blocking structure 5 will block the waste gas when the waste gas flows through the third stainless steel pipe 3. At the same time, when the waste gas flows through, the rotating base column 11, the mounting shaft 12 and the rotating blades 13 will rotate on the fixed base column 9, and the rotating rotating blades 13 will disrupt the waste gas flow, thereby achieving the purpose of reducing the waste gas flow rate, and finally allowing the waste gas to stay in the third stainless steel pipe 3 for a longer time, so that the sprayed component 4 can fully spray the waste gas, and thus the spray component 4 has a better spraying and cooling effect on the waste gas.
[0020] Furthermore, the first end of the third stainless steel tube 3 is fixedly installed with the second stainless steel tube 1, and the first end of the second stainless steel tube 1 is fixedly installed with the first stainless steel tube 2. A number of mounting holes 6 are evenly opened on the wall of the third stainless steel tube 3, and the mounting holes 6 pass through the wall of the third stainless steel tube 3 inside and outside. When in use, the first stainless steel tube 2 needs to be fixedly connected to the vent pipe of the hydrolysis reactor, and the diameters of the first stainless steel tube 2, the second stainless steel tube 1, and the third stainless steel tube 3 increase successively, so that when the exhaust gas flows through the first stainless steel tube 2, the second stainless steel tube 1, and the third stainless steel tube 3 in turn, the exhaust gas will be decompressed step by step.
[0021] Furthermore, the spray assembly 4 is composed of a water delivery pipe 7 and a spray head 8. There are several spray heads 8, and they are all fixedly installed on the water delivery pipe 7. The water delivery pipe 7 on the spray assembly 4 is located on the outside of the third stainless steel pipe 3. The spray head 8 is fixedly inserted from the outside to the inside into the mounting hole 6 opened on the third stainless steel pipe 3. When in use, the water delivery pipe 7 on the spray assembly 4 needs to be connected to the water pump through a pipeline. During use, the water pump can deliver cooling water to the water delivery pipe 7 through the pipeline, and then the cooling water in the water delivery pipe 7 will be sprayed into the third stainless steel pipe 3 by the spray head 8. At this time, the exhaust gas flowing through the third stainless steel pipe 3 is cooled by the cooling water sprayed by the spray head 8.
[0022] Furthermore, the fixed base column 9 on the exhaust gas blocking structure 5 is fixedly installed on the inner wall of the third stainless steel tube 3, and a mounting shaft hole 10 is opened at one end of the fixed base column 9, and the mounting shaft 12 is rotatably installed in the mounting shaft hole 10 opened on the fixed base column 9, and the rotating blades 13 are fixedly connected to the rotating base column 11. When the exhaust gas flows through the third stainless steel tube 3, the exhaust gas blocking structure 5 will block the exhaust gas flow, thereby slowing down the exhaust gas flow. At the same time, the exhaust gas flow will also push the rotating base column 11, the mounting shaft 12 and the rotating blades 13 to rotate on the fixed base column 9. As the rotating blades 13 rotate, turbulence will be formed, which will eventually further reduce the flow velocity of the exhaust gas flow in the third stainless steel tube 3, so that the exhaust gas flow can stay in the third stainless steel tube 3 for a longer time, so that the exhaust gas flow can more fully contact the cooling water sprayed by the spray head 8.
