Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon production, in particular to a device for recovering waste heat from high-temperature tail gas in the activated carbon production process. Background Art

[0002] Activated carbon is also called activated carbon black. It is amorphous carbon in black powder or granular form. Activated carbon has a strong "physical adsorption" and "chemical adsorption" effect. It is widely used in industry and has a large demand for industrial and civil use. In the production process of activated carbon, the temperature is the highest when the gas is generated. Under this condition, the temperature needs to be used quickly, and the gas needs to be filtered when it is recovered to clean up the impurities in the filtration process.

[0003] The Chinese patent (authorization announcement number: CN219757020U) proposes a waste heat recovery device for high-temperature tail gas in the process of activated carbon production, including a furnace body, the hollow part in the furnace body is a furnace, the outer layer of the furnace body is a shell, the furnace body is arranged from the outside to the inside, and adjacent shells are arranged in sequence with refractory wool and refractory bricks, and heat conduction plates are evenly arranged in the furnace from top to bottom in the horizontal direction, and heat conduction pipes are evenly arranged on the heat conduction plates along the longitudinal direction of the furnace, one end of the furnace body is a flue gas inlet, and the other end of the furnace body is a flue gas outlet, and a circulation pump A and a circulation pump B are respectively arranged on the outer sides of the two ends of the furnace body, and the circulation pump A is connected to the front end of the heat conduction pipe, and the circulation pump B is connected to the rear end of the heat conduction pipe, and a gate valve A is arranged on the front end pipeline of the heat conduction pipe, and a gate valve B is arranged on the rear end pipeline of the heat conduction pipe, and the heat conduction pipe is filled with circulating oil or circulating water. The circulating oil or circulating water transports heat energy to other processes in the production of activated carbon. The device has a simple structure and is easy to install, and can be widely used in activated carbon processing.

[0004] When the above scheme is used, since it can only provide easy installation during use, impurities need to be discharged and the exhaust gas needs to be utilized when the exhaust gas is discharged. In order to solve the problem of not being able to utilize the waste heat and filter the gas during recovery, the impurities in the filtration process need to be cleaned. Therefore, we propose a high-temperature exhaust waste heat recovery device in the activated carbon production process. Utility Model Content

[0014] The utility model provides a device for recovering waste heat from high-temperature tail gas during the production of activated carbon. Compared with the prior art, it has the following beneficial effects:

[0015] 1. A waste heat recovery device for high-temperature exhaust gas in the activated carbon production process. When the gas inside the chassis enters the exhaust main pipe, enters the connecting air pipe from the exhaust main pipe, and then enters the insulation pipe from the connecting air pipe. At this time, the heat of the gas will heat the insulation pipe, and the insulation pipe will insulate and heat the activated carbon. At this time, the gas will enter the L-shaped pipe through the insulation pipe, and then enter the exhaust main pipe from the L-shaped pipe, and be discharged from the exhaust main pipe.

However, when the connecting barrel rotates, when the connecting barrel abuts against the abutment block, the connecting barrel is lifted, and the rotating arm rotates at this time. When the connecting barrel leaves the abutment of the abutment block, the connecting barrel will vibrate to shake off the dust inside the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 6 As shown, the filtering mechanism 101 includes a third driving motor 24, the output end of the third driving motor 24 is fixedly connected to the second gear 23, the upper end surface of the chassis 1 is rotatably connected to a rotating column, the outer surface of the rotating column is fixedly installed with a first gear 22, the first gear 22 and the second gear 23 are meshed with each other, the upper end surface of the rotating column is fixedly connected to a rotating arm 21 with a reset function, specifically, a reset torsion spring is fixedly connected at the rotating position of the rotating arm 21, one side of the rotating arm 21 is rotatably connected to two groups of connecting arm rings 29, and the two groups of connecting arm rings 29 are symmetrically distributed, and a threaded rod 27 is threadedly connected between the two groups of connecting arm rings 29, a connecting barrel 26 is clamped between the connecting arm ring 29 and the rotating arm 21, and a number of filter screens 9 are installed inside the connecting barrel 26, the upper end surface of the chassis 1 is fixedly connected to an abutment block 25, and the outer surface of the abutment block 25 is provided with a curved surface, which can greatly reduce friction when abutment occurs, and the upper end surface of the chassis 1 is fixedly connected to a collar 28.

[0030] Working principle: coal is put into the chassis 1 through the hopper 6, and the first drive motor 13 is started at this time. The first drive motor 13 drives the third pulley 14 to rotate, and the third pulley 14 drives the fourth pulley 15 to rotate through the connecting belt 16, and the fourth pulley 15 drives the first ventilation disc 12 to rotate. Since the coal will enter between the first ventilation disc 12 and the second ventilation disc 20 and fall on the outer surface of the insulation tube 19, when the first ventilation disc 12 drives the second ventilation disc 20 to rotate through the insulation tube 19 and the elastic telescopic tube 18, the activated carbon will be driven to rotate together because it is on the outer surface of the insulation tube 19 and the elastic telescopic tube 18. At this time, the burner inside the chassis 1 will ignite the activated carbon;

[0031] The gas of the activated carbon will first pass through the connecting barrel 26, and the filter 9 inside the connecting barrel 26 will filter the gas. When the filter 9 is blocked, the third driving motor 24 is started at this time, and the third driving motor 24 drives the second gear 23 to rotate, and the second gear 23 drives the first gear 22 to rotate, and the first gear 22 drives the rotating column to rotate, and the rotating column drives the four groups of rotating arms 21 to rotate, and the rotating arm 21 drives the connecting barrel 26 to rotate ninety degrees, so that the replacement of the connecting barrel 26 can be completed. When it is necessary to remove the connecting barrel 26, the threaded rod 27 is rotated at this time, and the two groups of connecting arm rings 29 are loosened, and the connecting barrel 26 can be taken out at this time. However, when the connecting barrel 26 rotates, when the connecting barrel 26 abuts against the abutment block 25, the connecting barrel 26 is lifted at this time, and the rotating arm 21 rotates at this time. When the connecting barrel 26 leaves the abutment of the abutment block 25, the connecting barrel 26 will vibrate to shake off the dust inside the filter 9;

[0032] When the gas inside the chassis 1 enters the exhaust main pipe 5, enters the connecting air pipe 17 from the exhaust main pipe 5, and then enters the insulation pipe 19 from the connecting air pipe 17, the heat of the gas will heat the insulation pipe 19, and the insulation pipe 19 will insulate and heat the activated carbon. At this time, the gas enters the L-shaped pipe 3 through the insulation pipe 19, and then enters the exhaust main pipe 5 from the L-shaped pipe 3, and is discharged from the exhaust main pipe 5.

[0033] When the activated carbon needs to be taken out, the four sets of elastic telescopic tubes 18 are pulled to take out the activated carbon.
