Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an activated carbon adsorption device for waste gas treatment. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within the factory area of an enterprise. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have an accumulation effect, which will more seriously endanger human health. Therefore, the waste gas needs to be treated so that it can meet the emission standards before it can be discharged. The current waste gas purification treatment device mainly includes a spray tower and an activated carbon adsorption box. The spray liquid is introduced into the spray tower for spray treatment, and then the treated waste gas enters the activated carbon adsorption box for adsorption and then discharged.

[0003] In the related art, reference may be made to the Chinese utility model patent with authorization announcement number CN220656963U, which discloses an activated carbon adsorption box, including a drawer assembly and a box assembly. The drawer assembly is vertically mounted on the box assembly and is used to place the activated carbon plate. The box assembly is provided with several openings, and grooves are provided at the openings. The drawer assembly consists of a box and a lid, and the lid consists of a cover plate and a locking mechanism. The cover plate is a rectangular plate, and a through hole is provided in the middle of the cover plate for installing the locking mechanism. Slide grooves are provided on the inner side of the cover plate in the up, down, left and right directions respectively, and two handles are provided on the outer side of the cover plate. The locking mechanism consists of a rotating block, a long connecting rod, a short connecting rod, a long sliding rod, a short sliding rod and a knob. The drawer assembly can be stably mounted on the box assembly through the locking mechanism.

[0004] When replacing the activated carbon plate, you only need to rotate the knob to easily remove the drawer assembly. The operation is simple and convenient. However, you still need to close the air inlet of the activated carbon adsorption box to replace the activated carbon plate, which makes it impossible to achieve continuous treatment of the exhaust gas and reduces the efficiency of exhaust gas treatment.

During this process, the first adsorption channel continues to work without stopping for replacement, thereby realizing continuous treatment of exhaust gas and improving the efficiency of exhaust gas treatment.

[0009] Optionally, a vertically extending separation plate is provided in the adsorption box, and the separation plate divides the adsorption box into an air inlet chamber and an air outlet chamber. The air inlet is connected to the air inlet chamber, and the air outlet is connected to the air outlet chamber. A first upper partition is provided in the air inlet chamber, and a second upper partition is provided in the air outlet chamber. The first upper partition and the second upper partition are arranged opposite to each other, and a first air inlet cavity is formed between the first upper partition and the separation plate, and a first air outlet cavity is formed between the second upper partition and the separation plate. The top ends of the first air inlet cavity and the first air outlet cavity are connected, and multiple activated carbon boxes are evenly distributed in the first air inlet cavity and the first air outlet cavity. The exhaust gas passes through the air inlet, the first air inlet cavity, the first air outlet cavity, and then is discharged through the air outlet to form a first adsorption channel.

[0010] By adopting the above technical solution, the exhaust gas enters the air inlet chamber after passing through the air inlet, and part of the exhaust gas passes through the activated carbon box in the first air inlet chamber and enters the air outlet chamber from the top of the first air inlet chamber and is discharged from the air outlet after passing through the activated carbon box in the first air outlet chamber. By limiting the flow direction of the exhaust gas in the first adsorption channel, the contact time between the exhaust gas and the activated carbon box is increased, thereby improving the efficiency of exhaust gas treatment.

[0011] Optionally, a first lower partition is provided in the air inlet chamber, and the first lower partition is arranged opposite to the first upper partition. A second lower partition is provided in the air outlet chamber, and the second lower partition is arranged opposite to the first lower partition.

The bottom ends of the second air inlet chamber and the second air outlet chamber are connected, and multiple activated carbon boxes are evenly distributed in the second air inlet chamber and the second air outlet chamber. The exhaust gas passes through the air inlet, the second air inlet chamber, the second air outlet chamber, and then is discharged through the air outlet to form a second adsorption channel.

[0012] By adopting the above technical solution, the exhaust gas enters the air inlet chamber after passing through the air inlet, part of the exhaust gas enters the first air inlet chamber, and the rest of the exhaust gas enters the second air inlet chamber. After passing through the activated carbon box in the second air inlet chamber, it enters the air outlet chamber from the bottom end of the second air inlet chamber and is discharged from the air outlet after passing through the activated carbon box in the second air outlet chamber. By limiting the flow direction of the exhaust gas in the second adsorption channel, the contact time between the exhaust gas and the activated carbon box is increased, thereby improving the efficiency of exhaust gas treatment.

[0013] Optionally, the first control component includes:

[0014] a first upper baffle, rotatably mounted on the separation plate and configured to control the connection and disconnection between the first air inlet cavity and the air inlet; when the first air inlet cavity is disconnected from the air inlet, the first upper baffle abuts against the bottom end of the first upper baffle;

[0015] a second upper baffle, the second upper baffle being rotatably arranged on a side of the separation plate facing away from the first upper baffle, and the second upper baffle rotating in a direction opposite to that of the first upper baffle, the second upper baffle being used to control the connection and disconnection between the first air outlet cavity and the air outlet, and when the first air outlet cavity is disconnected from the air outlet, the second upper baffle abuts against the bottom end of the second upper baffle;

[0016] A driving member is provided on the adsorption box and is used to control the rotation of the first upper baffle and the second upper baffle.

[0017] By adopting the above technical solution, during normal operation, the first upper baffle and the second upper baffle both conflict with the separation plate. When the activated carbon box located in the first adsorption channel needs to be replaced, the driving member starts to drive the first upper baffle and the second upper baffle to rotate, so that the first upper baffle rotates to conflict with the bottom end of the first upper partition, and the second upper baffle rotates to conflict with the bottom end of the second upper partition. At this time, the first adsorption channel is in a closed state, and the exhaust gas is blocked by the first upper baffle and the separation plate and can only enter the second air inlet chamber. Then the activated carbon box in the first adsorption channel can be replaced. After the replacement is completed, the driving member starts to drive the first upper baffle and the second upper baffle back to the initial position. During this process, the exhaust gas is purified through the second adsorption channel, thereby realizing the replacement of the activated carbon box without stopping the machine and improving the exhaust gas treatment efficiency.

[0020] a second lower baffle, the second lower baffle being rotatably disposed on the second lower partition and being used to control the connection and disconnection between the second air outlet cavity and the air outlet;

[0021] The rotating member is provided on the adsorption box and is used to control the rotation of the first lower baffle and the second lower baffle.

[0022] By adopting the above technical solution, during normal operation, the first lower baffle and the second lower baffle are located at one end away from the separation plate. When the activated carbon box located in the second adsorption channel needs to be replaced, the rotating part starts to drive the first lower baffle and the second lower baffle to rotate, so that the first lower baffle rotates to conflict with the separation plate, and the second lower baffle rotates to conflict with the other side wall of the separation plate. At this time, the second adsorption channel is in a closed state, and the exhaust gas is blocked by the second upper baffle and the separation plate and can only enter the first air inlet cavity. Then the activated carbon box in the second adsorption channel can be replaced. After the replacement is completed, the rotating part starts to drive the first lower baffle and the second lower baffle back to the initial position. During this process, the exhaust gas is purified through the first adsorption channel, thereby realizing the replacement of the activated carbon box without stopping the machine and improving the exhaust gas treatment efficiency.

[0023] Optionally, a first limit plate is provided in the air inlet chamber, and when the air inlet is connected to the second air inlet chamber, the first lower baffle abuts against the first limit plate, and a second limit plate is provided in the air outlet chamber, and when the second air outlet chamber is connected to the air outlet, the second lower baffle abuts against the second limit plate.

[0024] By adopting the above technical solution, when the second adsorption channel is normally connected, the first lower baffle plate abuts against the first limit plate, and the second lower baffle plate abuts against the second limit plate, thereby guiding the intake and exhaust gases, reducing the probability of exhaust gas entering the space formed between the first lower baffle plate and the inner wall of the intake chamber, and reducing the probability of purified gas entering the space formed between the second lower baffle plate and the inner wall of the outlet chamber.

[0025] Optionally, an insertion groove is provided on the inner wall of the adsorption box, a magnetic plate is provided in the insertion groove, a magnetic sheet is provided on the activated carbon box, and the activated carbon box is arranged in the insertion groove by magnetic attraction.

When disassembling and replacing, the activated carbon box can be pulled to cause the magnetic sheet to separate from the magnetic plate, thereby improving the convenience of installation, positioning, disassembly and replacement of the activated carbon box.

[0027] Optionally, a push-pull plate is provided at one end of the activated carbon box away from the magnetic sheet, the push-pull plate is provided with a handle for leveraging, and the push-pull plate is also provided with a sealing ring. When working, the sealing ring is pressed tightly between the push-pull plate and the adsorption box.

[0028] By adopting the above technical solution, the activated carbon box is detached by pulling the push-pull plate. During installation, the push-pull plate is pushed so that the activated carbon box is installed in the insertion groove. At the same time, the sealing ring is pressed tightly between the push-pull plate and the adsorption box, thereby reducing the probability of exhaust gas escape.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Exhaust gas enters the adsorption box through the air inlet, part of the exhaust gas is adsorbed and purified by the activated carbon box in the first adsorption channel, and the remaining exhaust gas is adsorbed and purified by the activated carbon box in the second adsorption channel. The purified gas is discharged through the air outlet. When the activated carbon box needs to be replaced, the first adsorption channel is closed through the first control component, and then the activated carbon box located in the first adsorption channel can be replaced. After replacement, the first adsorption channel is opened. During this process, the second adsorption channel continues to work, and then the second adsorption channel is closed through the second control component, and then the activated carbon box located in the second adsorption channel can be replaced. After replacement, the second adsorption channel is opened again. During this process, the first adsorption channel continues to work without stopping for replacement, thereby realizing continuous treatment of exhaust gas and improving the efficiency of exhaust gas treatment.

[0031] 2. Part of the exhaust gas passes through the activated carbon box in the first air inlet chamber and enters the exhaust chamber from the top of the first air inlet chamber and is discharged from the exhaust port after passing through the activated carbon box in the first exhaust chamber. The remaining exhaust gas enters the second air inlet chamber, passes through the activated carbon box in the second air inlet chamber and enters the exhaust chamber from the bottom of the second air inlet chamber and is discharged from the exhaust port after passing through the activated carbon box in the second exhaust chamber. By limiting the flow direction of the exhaust gas in the first adsorption channel and the second adsorption channel, the contact time between the exhaust gas and the activated carbon box is increased, thereby improving the efficiency of exhaust gas treatment.

When the activated carbon box 2 in the second adsorption channel 14 needs to be replaced, the rotating member 43 is started to drive the first lower baffle 41 and the second lower baffle 42 to rotate in the opposite direction through the rotating rod 44, so that the first lower baffle 41 abuts against the opposite side walls of the separation plate 5 respectively. At this time, the second air inlet chamber 621 is disconnected from the air inlet 11, and the second air outlet chamber 721 is disconnected from the air outlet 12, so that the second adsorption channel 14 is in a closed state. Then the activated carbon box 2 located in the second adsorption channel 14 can be replaced. After replacement, the rotating member 43 drives the first lower baffle 41 and the second lower baffle 42 to move back to the initial position.

[0056] The working principle of the embodiment of this application is as follows:

[0057] When the gas circulates normally, part of the exhaust gas passes through the activated carbon box 2 in the first air inlet chamber 611 and then enters the exhaust chamber 7 from the top of the first air inlet chamber 611 and is discharged from the exhaust port 12 after passing through the activated carbon box 2 in the first exhaust chamber 711; the remaining exhaust gas enters the second air inlet chamber 621 and then enters the exhaust chamber 7 from the bottom of the second air inlet chamber 621 after passing through the activated carbon box 2 in the second air outlet chamber 721 and is discharged from the exhaust port 12. By limiting the flow direction of the exhaust gas in the first adsorption channel 13 and the second adsorption channel 14, the contact time of the exhaust gas with the activated carbon box 2 is increased, thereby improving the efficiency of exhaust gas treatment.

[0058] When the activated carbon box 2 in the first adsorption channel 13 needs to be replaced, the driving member 33 is started and drives the first upper baffle 31 and the second upper baffle 32 to rotate in the opposite direction through the driving rod 34, so that the first upper baffle 31 abuts against the bottom end of the first upper partition 61, and the second upper baffle 32 abuts against the bottom end of the second upper partition 71. At this time, the first air inlet chamber 611 is disconnected from the air inlet 11, and the first air outlet chamber 711 is disconnected from the air outlet 12, so that the first adsorption channel 13 is in a closed state, and then the activated carbon box 2 located in the first adsorption channel 13 can be replaced. After replacement, the driving member 33 drives the first upper baffle 31 and the second upper baffle 32 to move back to the initial position. During this process, the activated carbon box 2 in the second adsorption channel 14 continues to work. Similarly, the activated carbon box 2 in the second adsorption channel 14 can be replaced without stopping for replacement, thereby realizing continuous treatment of exhaust gas and improving the efficiency of exhaust gas treatment.
