[0002] Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons and nitrogen oxides, etc. The smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products, etc. The pollution of flue gas to the environment is a complex pollution of multiple poisons. Therefore, the emission of flue gas is one of the causes of air pollution. The flue gas needs to be purified before emission to reduce the harmful substances in the flue gas.

[0003] Deficiencies of the existing technology: In the existing technology, the treatment of flue gas usually requires high-temperature treatment, and the flue gas in a high-temperature state is likely to cause corrosion of equipment pipelines when discharged. Therefore, the flue gas needs to be cooled before discharge. The cooling device in the existing technology only adopts a single cooling method. The high-temperature flue gas entering is likely to cause corrosion and damage inside the cooling device, and the cooling effect is not obvious. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a double-layer flue gas cooling device to solve the problems existing in the above-mentioned background technology.

[0012] The technical effects and advantages of this utility model are:

[0013] 1. The utility model cools down the high-temperature flue gas entering the device by providing a first cooling component and a second cooling component.

The double-layer flue gas cooling device involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] The utility model provides a double-layer flue gas cooling device, such as Figure 1 and Figure 2 As shown, it includes a processing cabinet 1, an air inlet pipe 2 is fixedly connected to the left end of the processing cabinet 1, and the flue gas that needs to be cooled is transmitted to the processing cabinet 1 through the air inlet pipe 2, a first cooling component 3 is fixedly installed in the inner cavity of the processing cabinet 1, four supporting foot pads 4 are fixedly connected in a rectangular array at the bottom end of the processing cabinet 1, a cooling box 5 is fixedly connected to the top of the processing cabinet 1, a second cooling component 6 is fixedly installed in the inner cavity of the cooling box 5, a control panel 7 is fixedly installed on the left end of the cooling box 5, an air collecting box 8 is fixedly connected to the top of the cooling box 5, a guide plate 9 is fixedly connected to the top of the air collecting box 8, the top of the guide plate 9 is set to an arc shape, and the flow direction of the flue gas is ensured by the arc-shaped guide plate 9, and the right end of the air collecting box 8 is fixedly connected to the outlet pipe 10, so that the flue gas can be better discharged through the outlet pipe 10.

[0022] Further, such as Figure 3 and Figure 4 As shown, the first cooling component 3 includes an air cooler 31, and the left end of the air cooler 31 is fixedly connected to a first connecting pipe 32, and the left end of the first connecting pipe 32 passes through the left end of the processing cabinet 1, and the first connecting pipe 32 is connected to the air inlet pipe 2. The high-temperature flue gas is transmitted to the air cooler 31 through the air inlet pipe 2 through the first connecting pipe 32, and the flue gas in a high-temperature state is first cooled by the air cooler 31. The top of the air cooler 31 is fixedly connected to a second connecting pipe 33, and the top of the second connecting pipe 33 is fixedly connected to a transmission pipe 34. The top of the transmission pipe 34 passes through the bottom end of the cooling box 5, and the transmission pipe 34 is connected to the cooling box 5. The flue gas cooled by the air cooler 31 is transmitted to the inner cavity of the transmission pipe 34 through the second connecting pipe 33, and the flue gas is transmitted to the inner cavity of the cooling box 5 through the transmission pipe 34, so as to avoid directly transmitting the high-temperature flue gas into the device, which may cause corrosion damage to the device after a long time.

[0023] Furthermore, the second cooling component 6 includes two circulating water tanks 61, and a plurality of cooling water pipes 62 are fixedly connected at equal distances between the two circulating water tanks 61. The two circulating water tanks 61 are respectively fixedly installed at the front and rear ends of the cooling box 5. The condensed water in the cooling water pipes 62 is always circulated through the circulating water tanks 61, ensuring that the condensed water in the cooling water pipes 62 is always in a low-temperature state, thereby ensuring the cooling effect of the second cooling component 6. The cooling water pipes 62 are fixedly connected to the inner cavity of the cooling box 5 at equal distances, and are transmitted to the flue gas in the cooling box 5 through the transmission pipe 34. The flue gas is cooled and cooled through the evenly distributed cooling water pipes 62.

[0024] Furthermore, the high-temperature flue gas entering the device is subjected to a double cooling treatment by the first cooling component 3 and the second cooling component 6, thereby increasing the cooling effect of the high-temperature flue gas. After the cooling treatment, the flue gas passes through the guide plate 9 with an arc at the top, so that the flue gas can flow along the direction of the exhaust pipe 10, ensuring that the flue gas can be smoothly discharged from the device through the exhaust pipe 10.

[0025] The working principle of the utility model is as follows: first, the high-temperature flue gas that needs to be cooled is connected to the air inlet pipe 2, the first connecting pipe 32 is connected to the air inlet pipe 2, and the high-temperature flue gas is transmitted to the air cooler 31 through the first connecting pipe 32 through the air inlet pipe 2. The flue gas in the high-temperature state is first cooled by the air cooler 31, and the flue gas cooled by the air cooler 31 is transmitted to the inner cavity of the transmission pipe 34 through the second connecting pipe 33. The flue gas is transmitted to the inner cavity of the cooling box 5 through the transmission pipe 34, avoiding directly transmitting the high-temperature flue gas into the device for a long time. Afterwards, the device will be corroded and damaged. After the first cooling component 3 is processed, the flue gas flows upward through the second cooling component 6, and is transmitted to the flue gas in the cooling box 5 through the transmission pipe 34. The flue gas is cooled and cooled through the evenly distributed cooling water pipe 62. The condensed water in the cooling water pipe 62 is always circulated through the circulating water tank 61 to ensure that the condensed water in the cooling water pipe 62 is always in a low-temperature state. After the cooling treatment, the flue gas passes through the guide plate 9 with an arc at the top, so that the flue gas can be discharged from the device smoothly through the outlet pipe 10.
