Description

Technical Field

[0001] The utility model relates to the technical field of atmospheric pressure tanks, and particularly relates to a flue gas recovery device for an atmospheric pressure tank. Background Technique

[0002] In the production processes of the metallurgy and chemical industries, most tanks are atmospheric pressure equipment. During the process production, a large amount of heat is carried by the materials into the atmospheric pressure tank for liquid volume buffering, and the high-temperature flue gas is discharged through the exhaust pipe. The discharged flue gas is directly discharged into the atmosphere. The flue gas not only has a relatively high temperature but also contains some materials. Direct discharge into the atmosphere will cause energy waste, increase production costs, seriously pollute the production site, and bring safety risks at the same time. Content of the Utility Model

[0003] Aiming at the technical problems existing in the background technique, the purpose of the utility model is to provide a flue gas recovery device for an atmospheric pressure tank, which can not only prevent the flue gas from being directly discharged into the atmosphere but also recover the flue gas.

[0025] Embodiment

[0026] As Figure 1 、 2 As shown in Figures 1, 2, 3, 4, and 6, a flue gas recovery device for an atmospheric tank includes an atmospheric tank 1 and a flue gas recovery device provided on the atmospheric tank 1. An exhaust pipe 2 is provided on the atmospheric tank 1. The flue gas recovery device includes a sealing box 3 and a cover 5. A connecting hole 31 is provided on the sealing box 3. The exhaust pipe 2 is connected to the connecting hole 31. The sealing box 3 is directly connected to the exhaust pipe 2, and the exhaust pipe 2 extends into the sealing box 3. Flue gas flows out of the atmospheric tank 1 into the exhaust pipe 2 and then into the sealing box 3 from the exhaust pipe 2. A return pipe 7 is provided on the sealing box 3, and a water outlet hole 32 is also provided on the sealing box 3. The return pipe 7 is connected to the water outlet hole 32. The water outlet hole 32 is provided at the bottom of the sealing box 3. Circulating water can be directly discharged from the water outlet hole 32. The cover 5 is provided in the sealing box 3 and buckled above the exhaust pipe 2. A water inlet pipe 6 is provided on the cover 5, and a water inlet hole 51 is provided on the cover 5. The water inlet pipe 6 is connected to the water inlet hole 51. A cavity Ⅰ A is formed between the cover 5 and the exhaust pipe 2. Both the water inlet pipe 6 and the return pipe 7 are provided in the cavity Ⅰ A. Flue gas enters the sealing box 3 and is blocked in the cavity Ⅰ A by the cover 5. Circulating water enters the sealing box 3 from the water inlet pipe 6 and flows out of the return pipe 7 to other equipment.

[0027] As Figure 1 、 2, as shown in Figures 3, there is a connecting ring 101 provided at the upper end of the atmospheric tank 1, and one end of the sealing box 3 is provided with a connecting rod 33. The connecting rod 33 is connected to the connecting ring 101. The flue gas recovery device is fixed on the atmospheric tank 1 through the connecting rod 33 and the connecting ring 101. The atmospheric tank 1 is an existing technology. There is a staircase around the atmospheric tank 1, and the staircase reaches the position of the connecting ring 101, which is convenient for workers to install the flue gas recovery device.

[0028] As Figure 1 , 2 , 3, 4, 6 show that a cavity ⅡB is connected between the cover 5 and the sealing box 3. A liquid is introduced into the cavity ⅡB. The liquid is an aqueous solution. The aqueous solution is outside the cover 5, which can prevent the flue gas inside the cover 5 from flowing out from the connection point between the cover 5 and the sealing box 3, achieving maximum sealing to prevent the flue gas from flowing into the atmosphere. At the same time, using the aqueous solution will reduce the cost of sealing and is more convenient for subsequent disassembly or maintenance.

[0029] As Figure 1 , 2 , 3, 5, 6 show that a cleaning component is provided on the sealing box 3. The cleaning component includes a push block 8 and a support block 81. The push block 8 is slidably arranged on the sealing box 3. The support block 81 is connected to the push block 8, and the support block 81 extends into the cavity ⅡB. A cleaning towel can be placed at the bottom of the support block 81. A chute Ⅰ4 is provided on the inner wall of the sealing box 3, and a chute Ⅱ41 is provided on the outer wall. A groove 801 with the same shape as the wall of the sealing box 3 is provided inside the push block 8. A slider Ⅰ802 and a slider Ⅱ803 are provided in the groove 801. The slider Ⅰ802 and the slider Ⅱ803 are fixedly connected to the push block 8. The slider Ⅰ802 is connected in the chute Ⅰ4, and the slider Ⅱ803 is connected in the chute Ⅱ41. If workers directly clean the flue gas recovery device, they need to put their hands into the cavity ⅡB, and this cleaning method is not efficient enough. After designing the cleaning component, workers only need to climb from the staircase outside the atmospheric tank 1 to the flue gas recovery device, place the cleaning towel at the position of the cavity ⅡB, push the push block 8, so that the push block 8 and the support block 81 move along the edge of the sealing box 3. During the movement of the support block 81, the cleaning towel is driven to clean the bottom of the cavity ⅡB, which can not only ensure the cleaning quality but also speed up the cleaning process.
