Description

Technical Field

[0001] This utility model relates to the field of activated carbon regeneration technology, and in particular to an activated carbon regeneration and purification device. Background Technology

[0002] Activated carbon is widely used to remove pollutants in fields such as industrial waste gas treatment and water purification due to its excellent adsorption performance. Activated carbon regeneration purification devices capture pollutants during the adsorption stage and then restore the adsorption capacity of saturated activated carbon through regeneration stages such as heating desorption and catalytic combustion. At the same time, the pollutants generated during desorption are treated to be harmless.

[0003] However, traditional activated carbon regeneration and purification devices often use a single or a small number of electric heating tubes arranged in a concentrated manner. As a result, the activated carbon in the area far from the electric heating tubes cannot completely release the adsorbed pollutants because the temperature does not reach the desorption threshold, thus reducing the qualified rate of activated carbon regeneration. For example, in traditional activated carbon regeneration and purification devices used in factories, the heating mechanism only has a few electric heating tubes installed on one side of the outer wall of the heating box. When regenerating granular activated carbon, the temperature of the activated carbon in the edge area is always maintained at a level that cannot meet the reaction regulation conditions. As a result, some activated carbon cannot be completely desorbed due to insufficient temperature and needs to be regenerated a second time, which affects production efficiency. Utility Model Content

[0004] This utility model discloses an activated carbon regeneration and purification device, which aims to solve the technical problem that traditional activated carbon regeneration and purification devices often use a single or a small number of electric heating tubes arranged in a concentrated manner, which results in activated carbon far from the electric heating tubes not being able to completely release adsorbed pollutants because the temperature does not reach the desorption threshold, thus reducing the qualified rate of activated carbon regeneration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An activated carbon regeneration and purification device includes a reaction chamber, a filter plate connected to one outer wall of the reaction chamber, and multiple equally spaced racks installed on the outer walls of both reaction chambers. It also includes: a heating mechanism comprising a heating box connected inside the reaction chamber; mounting cavities on opposite outer walls of the reaction chamber and the heating box; a power supply box connected to one outer wall of the reaction chamber; heating tubes connected to the output end of the power supply box; multiple heating tubes equally spaced on the outer wall of the heating box; multiple fins equally spaced on the outer wall of the heating tubes closest to the heating box; and multiple fixing blocks connected to the outer wall of the heating tubes furthest from the heating box, with the fixing blocks connected to the inner wall of the same reaction chamber; and a catalytic combustion mechanism located on one outer wall of both reaction chambers.

[0006] By adopting the above technical solution, the heating mechanism includes a heating box connected inside the reaction chamber. The heating box provides an installation position for the internal rack and forms a heating cavity. An installation cavity is set between the reaction chamber and the heating box to accommodate multiple heating tubes. The power supply box connected to the outer wall of one side of the reaction chamber is activated to heat the multiple heating tubes. The multiple heating tubes are evenly distributed on the outer wall of the heating box, so that the heat is more evenly distributed inside the heating box. The side of the heating tube closest to the heating box has multiple fins evenly distributed to increase the heat dissipation area of ​​the heating tube. At the same time, the side of the heating tube away from the heating box has multiple fixing blocks connected to it to enhance the stability of the heating tube.

[0007] As a further embodiment of this utility model: the catalytic combustion mechanism includes a common exhaust gas inlet pipe connected to one side outer wall of the two reaction chambers, an adsorption gas inlet pipe provided below the exhaust gas inlet pipe, a common adsorption gas outlet pipe connected to the other side outer wall of the two reaction chambers, an exhaust gas outlet pipe provided below the adsorption gas outlet pipe, the exhaust gas inlet pipe, the adsorption gas outlet pipe, the exhaust gas outlet pipe and the adsorption gas inlet pipe are all Y-shaped structures, a second fan is connected to the side outer wall of the adsorption gas outlet pipe away from the reaction chamber, and a catalytic combustion device is connected to the side outer wall of the second fan.

[0008] By adopting the above technical solution, the catalytic combustion mechanism includes a common exhaust gas inlet pipe connected to the outer wall of one side of the two reaction chambers. This exhaust gas inlet pipe introduces the pollutant-containing exhaust gas into the two reaction chambers for adsorption and purification. Simultaneously, a common adsorbed gas outlet pipe is connected to the outer wall of the other side of the two reaction chambers. This adsorbed gas outlet pipe guides the high-concentration gas containing adsorbed pollutants from the reaction chambers into the airflow catalytic combustion device. Below the exhaust gas inlet pipe and the adsorbed gas outlet pipe are respectively provided an adsorbed gas inlet pipe and an exhaust gas outlet pipe. The adsorbed gas inlet pipe guides the gas treated by catalytic combustion into the two reaction chambers, achieving gas recycling. The exhaust gas outlet pipe guides the purified gas from the reaction chambers into the two reaction chambers. The gas is discharged, and at this time, the exhaust gas inlet pipe, the adsorbed gas outlet pipe, the exhaust gas outlet pipe, and the adsorbed gas inlet pipe are all Y-shaped structures, so that each pipe is connected to the two reaction boxes, which facilitates the distribution of gas to the two reaction boxes. Thus, when one reaction box needs to desorb the activated carbon inside, the other reaction box can adsorb the exhaust gas, thereby reducing downtime and improving working efficiency. By starting the second fan, the gas flow in the adsorbed gas outlet pipe will be powered, pushing the pollutant gas into the air volume catalytic combustion device. The air volume catalytic combustion device is used to catalytically combust the introduced high-concentration pollutant gas, oxidizing and decomposing the pollutants into harmless carbon dioxide and water.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. To improve the heating uniformity of activated carbon inside the heating chamber, an installation cavity is set inside the heating chamber and the reaction chamber between them to accommodate multiple electric heating tubes. The electric heating tubes are powered by the power supply box. By distributing multiple electric heating tubes at equal intervals on the outer wall of the heating chamber, and by increasing the heat dissipation area with multiple fins on the outer wall of the side of the electric heating tubes close to the heating chamber, heat can be transferred to the interior of the heating chamber more evenly, effectively improving the temperature distribution uniformity inside the heating chamber, and thus improving the heating uniformity of the activated carbon on the rack.

[0010] 2. Improve the working efficiency of the device. The Y-shaped structure of the exhaust gas inlet pipe, adsorbed gas outlet pipe, exhaust gas outlet pipe and adsorbed gas inlet pipe enables the connection between each pipe and the two reaction chambers. At this time, when one reaction chamber is desorbed by activated carbon, the other reaction chamber can continuously introduce the waste gas to be treated for adsorption and purification through the exhaust gas inlet pipe. By avoiding the shutdown of the device caused by desorption of a single reaction chamber, the overall working efficiency is effectively improved.

[0020] Specifically, the heating mechanism includes a heating box 17 connected inside the reaction chamber 1. The heating box 17 provides an installation position for the internal placement rack 10 and forms a heating cavity. An installation cavity is provided between the reaction chamber 1 and the heating box 17 to accommodate multiple electric heating tubes 14. The power supply box 13 connected to the outer wall of one side of the reaction chamber 1 is activated to heat the multiple electric heating tubes 14. The multiple electric heating tubes 14 are evenly distributed on the outer wall of the heating box 17, so that the heat is more evenly distributed inside the heating box 17. Multiple fins 16 are evenly distributed on the outer wall of the electric heating tubes 14 near the heating box 17 to increase the heat dissipation area of ​​the electric heating tubes 14. At the same time, multiple fixing blocks 15 are connected to the outer wall of the electric heating tubes 14 away from the heating box 17 to enhance the stability of the electric heating tubes 14.

[0021] Among them, the heating tube 14 has a ring structure, and multiple heating tubes 14 are connected in series. The multiple ring-structured heating tubes 14 are wrapped around the outer wall of the heating box 17, so that the interior of the heating box 17 is heated evenly.

The partitions 12 are used for heat conduction and space separation around the placement rack 10.

[0023] Reference Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, the catalytic combustion mechanism includes a common exhaust gas inlet pipe 2 connected to the outer wall of one side of the two reaction chambers 1. An adsorption gas inlet pipe 9 is provided below the exhaust gas inlet pipe 2. The other outer wall of the two reaction chambers 1 is connected to a common adsorption gas outlet pipe 3. An exhaust gas outlet pipe 4 is provided below the adsorption gas outlet pipe 3. The exhaust gas inlet pipe 2, the adsorption gas outlet pipe 3, the exhaust gas outlet pipe 4, and the adsorption gas inlet pipe 9 are all Y-shaped structures. A second fan 6 is connected to the outer wall of the adsorption gas outlet pipe 3 on the side away from the reaction chamber 1. A catalytic combustion device 7 is connected to the outer wall of the second fan 6 on the side.

[0024] Specifically, the catalytic combustion mechanism includes a common exhaust gas inlet pipe 2 connected to the outer wall of one side of the two reaction chambers 1. The exhaust gas inlet pipe 2 is used to introduce the pollutant-containing exhaust gas to be treated into the two reaction chambers 1 for adsorption and purification. At this time, a common adsorbed gas outlet pipe 3 is connected to the outer wall of the other side of the two reaction chambers 1. The adsorbed gas outlet pipe 3 is used to introduce the high-concentration gas with adsorbed pollutants in the reaction chamber 1 into the air volume catalytic combustion device 7. At this time, an adsorbed gas inlet pipe 9 and an exhaust gas outlet pipe 4 are respectively provided below the exhaust gas inlet pipe 2 and the adsorbed gas outlet pipe 3. The adsorbed gas inlet pipe 9 is used to introduce the gas treated by catalytic combustion into the two reaction chambers 1 to realize gas recycling. The exhaust gas outlet pipe 4 is used to introduce the purified gas in the reaction chamber 1 into the two reaction chambers 1. As the gas is discharged, the exhaust gas inlet pipe 2, the adsorbed gas outlet pipe 3, the exhaust gas outlet pipe 4, and the adsorbed gas inlet pipe 9 are all Y-shaped structures, thus connecting each pipe to the two reaction chambers 1. This facilitates the distribution of gas to the two reaction chambers 1, allowing the other reaction chamber 1 to adsorb the exhaust gas while one reaction chamber 1 needs to desorb the activated carbon inside, thereby reducing downtime and improving work efficiency. By starting the second fan 6, the gas flow in the adsorbed gas outlet pipe 3 is powered, pushing the pollutant gas into the airflow catalytic combustion device 7. The airflow catalytic combustion device 7 is used to catalytically combust the introduced high-concentration pollutant gas, oxidizing and decomposing the pollutants into harmless carbon dioxide and water.

[0025] The exhaust gas outlet pipe 4 and the adsorption gas inlet pipe 9 are both connected to the outer walls of the two reaction chambers 1. The outer wall of the air volume catalytic combustion device 7 away from the second fan 6 is connected to the outer wall of the adsorption gas inlet pipe 9. The exhaust gas outlet pipe 4 and the adsorption gas inlet pipe 9 are both connected to the outer walls of the two reaction chambers 1, respectively undertaking the functions of purifying gas discharge and treating gas circulation. At this time, by starting the second fan 6 connected to the outer wall of the air volume catalytic combustion device 7, the clean gas treated by catalytic combustion can be returned to the reaction chamber 1 through the adsorption gas inlet pipe 9.

[0026] Specifically, valves are installed on the branch pipes of the exhaust gas inlet pipe 2, the adsorbed gas outlet pipe 3, the exhaust gas outlet pipe 4, and the adsorbed gas inlet pipe 9. The valves are used to control the opening and closing of each branch pipe and to control the flow direction of the gas entering the two reaction chambers 1.

[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, a waste gas outlet pipe 4 is connected to one side of the outer wall of the reaction chamber 1, a first fan 5 is connected to one side of the outer wall of the waste gas outlet pipe 4, and a smoke exhaust pipe 8 is connected to one side of the outer wall of the first fan 5.

[0028] Specifically, the exhaust gas outlet pipe 4 is used to discharge the purified gas that meets the standards. The first fan 5 connected to the outer wall of one side of the exhaust gas outlet pipe 4 provides power for the gas flow in the exhaust gas outlet pipe 4. At this time, a smoke exhaust pipe 8 is connected to the outer wall of one side of the first fan 5. The smoke exhaust pipe 8 is used to safely discharge the purified gas discharged by the first fan 5 into the atmosphere.

[0029] Working principle: In use, by opening the valve of one branch pipe of the exhaust gas inlet pipe 2 and closing the valve of the other branch pipe, the pollutant-containing exhaust gas to be treated is introduced into one of the connected reaction chambers 1 through the Y-shaped exhaust gas inlet pipe 2. Simultaneously, multiple racks 10 connected inside the reaction chamber 1 are used to hold the activated carbon to be adsorbed, while the filter plate 11 is used to initially filter the exhaust gas entering the reaction chamber 1, removing large particulate impurities to prevent clogging of the activated carbon pores. Then, by activating the valve connected to the exhaust gas outlet... The first fan 5 on one side of the outer wall of the gas pipe 4 drives the exhaust gas through the filter plate 11 and into full contact with the activated carbon on the rack 10. The activated carbon, with its porous structure, captures and fixes the pollutants in the exhaust gas in the pores, thus completing the purification of the exhaust gas. Finally, the purified exhaust gas is discharged through the exhaust pipe 8. When the activated carbon in one of the reaction chambers 1 is saturated, the valves of its exhaust gas inlet pipe 2 and exhaust gas outlet pipe 4 are closed, and the valves of its adsorbed gas outlet pipe 3 and adsorbed gas inlet pipe 9 are opened. At the same time, the exhaust gas inlet pipe of the other reaction chamber 1 is opened. The valves of the gas pipe 2 and the exhaust gas outlet pipe 4 ensure continuous adsorption, preventing equipment shutdown and improving working efficiency. For one of the reaction chambers 1 that requires activated carbon regeneration, the power supply box 13 of its internal heating mechanism is activated to supply power to multiple heating tubes 14 and generate heat. At this time, the multiple heating tubes 14 with an annular structure are evenly distributed on the outer wall of the heating chamber 17. The fins 16 on the side near the heating chamber 17 can increase the heat dissipation area, thereby achieving rapid and uniform heat transfer to the interior of the heating chamber 17. The partition on the outer wall of the rack 10... Plate 12 is used to separate the installation cavity and the placement rack 10, so that the temperature inside the heating box 17 is uniformly raised to the temperature required for activated carbon desorption. At this time, by opening the valve of the branch pipe of the adsorption gas outlet pipe 3 corresponding to the reaction box 1 and starting the second fan 6, the high-concentration pollutant gas in the reaction box 1 is drawn to the air volume catalytic combustion device 7 through the Y-shaped structure of the adsorption gas outlet pipe 3. The air volume catalytic combustion device 7 is used to carry out catalytic combustion reaction on the introduced high-concentration pollutant gas, oxidizing and decomposing the pollutants into harmless carbon dioxide and water.
