Description

Technical Field

[0001] This utility model relates to the field of spray equipment, and in particular to a spray cooling device for flue gas in a carbonization workshop. Background Technology

[0002] The flue gas discharged from the carbonization furnace needs to be cooled down to meet the entry conditions of subsequent processing equipment and avoid high temperature damage to the equipment. The existing shell and tube heat exchangers exchange heat through the metal wall of the flue, which can cool the flue without changing the composition of the flue gas and without generating wastewater. However, the installation structure is fixed, the modification cost is high, and it is not conducive to flexible adjustment according to the actual cooling situation. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a flue gas spray cooling device for carbonization workshops, which features a flexible installation structure, convenient adjustment, and low modification costs.

[0004] The technical solution of this utility model is as follows:

[0005] A flue gas spray cooling device for a carbonization workshop includes a spraying section and a collecting section. The spraying section includes several annular spray pipes, and several nozzles are arranged circumferentially on the inner side of the spray pipes. The spray pipes are provided with water inlet connectors for connecting water supply pipes. The spray pipes are arranged vertically and have a support frame at the bottom. The collecting section includes a water collection tank, which passes axially through the spray pipes and is located at the bottom of the inner side of the spray pipes. The bottom of the water collection tank is provided with a drain outlet.

[0006] In a further technical solution, clamping structures are provided on both sides of the spray pipe.

[0007] In a further technical solution, the clamping structure includes a connecting block and a stud. The connecting block is symmetrically arranged on both sides of the spray pipe, and a screw hole is opened horizontally and radially in the middle of the connecting block. The stud passes through the screw hole.

[0008] In a further technical solution, the bottom of the water collection tank is provided with a slide rail, and the inner bottom of the spray pipe is provided with a slider that is slidably connected to the slide rail.

[0009] In a further technical solution, the bottom of the support frame is provided with rollers.

[0010] In a further technical solution, the support frame is arranged in pairs on both sides of the bottom of the spray pipe, including a column, a base plate and an inclined support rod. The two ends of the column are respectively connected to the spray pipe and the base plate, and the two ends of the inclined support rod are connected to the base plate and the column. The roller is located at the bottom of the base plate.

[0011] In a further technical solution, the water collection tank is provided with several filter screens at intervals.

[0012] The beneficial effects of this utility model are:

[0013] 1. The spray pipes of this device can be sleeved on the outside of the flue and supported by a support frame. Each nozzle faces the outside of the flue, and a water source can be connected to spray the flue in all directions through the nozzles for indirect cooling. This facilitates the cooling of the flue gas before it enters subsequent equipment for treatment. The water collection tank is located at the bottom of the flue, and most of the water after spraying can flow into the water collection tank and be discharged into a designated location through the drain outlet for recycling and subsequent spraying. The number and position of the spray sections can be adjusted according to the actual cooling requirements of the flue, and the modification cost is low.

[0014] 2. The spray pipes can slide relative to the water collection tank, making it easy to adjust the distance between two adjacent spray pipes. The overall position of the device can also be adjusted by rollers, making the adjustment convenient and quick.

[0015] 3. The filter screen can filter impurities that enter the water collection tank and is easy to clean, reducing the content of impurities in the recycled water. Attached Figure Description

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example:

[0024] like Figures 1-3As shown, a carbonization workshop flue gas spray cooling device includes a spraying section and a collection section. The spraying section includes several annular spray pipes 10, and four nozzles 11 are evenly arranged circumferentially on the inner side of the spray pipes 10. The nozzles 11 are atomizing nozzles. The radial direction of the spray pipes 10 is vertical, that is, the entire structure is arranged vertically, mainly for the horizontal flue gas 30 to pass through. In special cases, it can be adjusted according to the angle of the flue gas 30 so that the axial direction of the spray pipes 10 is parallel to the flue gas 30. A water inlet connector 12 is provided at the top of the spray pipes 10 and a support frame 20 is provided at the bottom. The collection section includes a water collection tank 40, which is axially passed through the spray pipes 10 and located at the bottom of the inner side of the spray pipes 10, so that the water collection tank 40 can be located at the bottom of the flue gas 30. A drain outlet 41 is provided at one end of the bottom of the water collection tank 40.

[0025] The cooling device can be used in conjunction with a water storage tank or water tank. The water storage tank or water tank is connected to a water supply pipe via a water pump. The water supply pipe can be connected to multiple branch pipes via branch joints. The ends of the branch pipes are connected to water inlet joints 12 respectively. The water collection tank 40 is located above the water storage tank or water tank. Its drain outlet 41 can be equipped with a drain pipe connected to the water storage tank or water tank for water return circulation.

[0026] The working principle of the above technical solution is as follows:

[0027] Spray water enters from the inlet connector 12 and is sprayed out from each nozzle 11 to spray and cool the outer wall of the flue 30, achieving indirect cooling of the flue gas. The water collection tank 40 is located at the bottom of the flue 30 at this time. Most of the water after spraying can flow into the water collection tank 40 and be discharged into the water storage tank or water tank through the drain outlet 41. It can be recycled and used for subsequent spraying. The number and position of the spraying parts can be adjusted according to the actual cooling needs of the flue 30, and the modification cost is low.

[0028] In another embodiment, such as Figure 1-2 As shown, the spray pipe 10 has clamping structures on both sides. The clamping structures include connecting blocks 51 and studs 52. The connecting blocks 51 are symmetrically arranged on both sides of the spray pipe 10. A screw hole 53 is opened horizontally and radially in the middle of the connecting block 51, and the stud 52 passes through the screw hole 53.

[0029] When it is necessary to fix the position of the spray pipe 10, the stud 52 can be rotated relative to the connecting block 51 so that the ends of the studs 52 on both sides press against the outer wall of the flue 30 to form a clamping fixation.

[0030] In another embodiment, such as Figure 1 and Figure 4As shown, the bottom of the water collection tank 40 is provided with a slide rail, and the inner bottom of the spray pipe 10 is provided with a slider that is slidably connected to the slide rail; the support frame 20 is provided in pairs on both sides of the bottom of the spray pipe 10, including a column 21, a base plate 22 and an inclined support rod 23. The two ends of the column 21 are respectively connected to the spray pipe 10 and the base plate 22, and the two ends of the inclined support rod 23 are connected to the base plate 22 and the column 21. The bottom of the base plate 22 is provided with a roller 24.

[0031] The spray pipe 10 can slide easily relative to the water collection tank 40 via the slider rail, and the position of the spray pipe 10 can be easily adjusted with the help of the roller 24.

[0032] In another embodiment, such as Figure 3 As shown, a number of filter screens 42 are spaced apart inside the water collection tank 40. Slots can be provided on both sides of the top of the water collection tank 40, and the filter screens 42 can be installed in the water collection tank 40 by plugging them in, making them easy to remove and clean.

[0033] The filter screen 42 can filter impurities entering the water collection tank 40 and is easy to clean, reducing the impurity content in the recycled water; the spaced filter screens 42 can block external impurities in sections, preventing impurities from being too concentrated.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
