Description

Technical Field

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

[0002] Activated carbon adsorption device is the best purification equipment for treating organic waste gas. Activated carbon adsorption is an effective measure to remove water odor, natural and synthetic dissolved organic matter, micro-pollutants, etc. Most of the larger organic molecules, aromatic compounds, halogenated alkynes, etc. can be firmly adsorbed on the surface or in the gaps of activated carbon, and it has a significant removal effect on humus, synthetic organic matter and low molecular weight organic matter.

[0003] There will be a pressure difference between the air inlet and outlet of the activated carbon adsorption device, which is related to the following factors:

[0004] (1) The activated carbon adsorption device is clogged by dirty particles (slices, grinding, dust, activated carbon powder, water vapor and other objects), resulting in increased pressure loss;

[0005] (2) The filter screen blocks particles larger than 5 microns, causing the pressure loss to gradually increase;

[0006] (3) The activated carbon adsorption device reaches saturation, causing the pressure loss to increase. In addition, the activated carbon adsorption device's own powder particles or dirty particles from the outside fill the active gap, causing the pressure loss to increase;

[0007] The above reasons may cause the pressure difference between the activated carbon inlet and outlet to increase, thereby increasing the system pressure loss and reducing the air volume loss treatment effect. Therefore, when an abnormal pressure drop occurs, it is necessary to promptly carry out maintenance and troubleshooting. However, in the prior art, workers are usually required to actively observe the pressure gauge to judge the pressure drop. When an abnormal pressure drop occurs, no alarm will be issued, which can easily lead to the abnormal pressure drop being discovered untimely, and thus the failure of the activated carbon adsorption device cannot be timely eliminated. Utility Model Content

[0008] The purpose of the utility model is to overcome the above-mentioned technical deficiencies and to propose an activated carbon adsorption device to solve the technical problem in the prior art that when an abnormal pressure drop occurs, no alarm is issued, which easily leads to the abnormal pressure drop being not discovered in time, and thus the failure of the activated carbon adsorption device cannot be eliminated in time.

[0009] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0010] The utility model provides an activated carbon adsorption device, comprising:

[0011] Cylinder;

[0017] In some embodiments, the alarm mechanism further includes a second fixing seat, the second fixing seat is fixed in the connecting tube, a second plug hole is provided on the second fixing seat, and the guide rod is slidably inserted in the second plug hole.

[0018] In some embodiments, the alarm mechanism further includes a protrusion, which is fixed on the guide rod. When the piston moves to a preset position, the contact of the micro switch is pressed by the protrusion.

[0023] Compared with the prior art, the beneficial effect of the activated carbon adsorption device provided by the utility model is as follows: when in use, the cylinder is connected to the exhaust gas pipe, the exhaust gas enters the air inlet chamber, enters the air outlet chamber after being processed by the activated carbon layer, and is then discharged to the subsequent processing device. Due to the presence of the activated carbon layer, there will be a pressure difference between the air inlet chamber and the air outlet chamber, thereby causing the piston to move and compress the elastic part. When the restoring force provided by the elastic part under a certain compression amount is balanced with the pressure difference between the air inlet chamber and the air outlet chamber, the piston no longer moves.

Through this device, an alarm can be sounded in time when an abnormal pressure drop occurs, so as to timely eliminate the fault of the activated carbon adsorption device.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] In order to solve the technical problem that when an abnormal pressure drop occurs, no alarm is sounded, which easily leads to the abnormal pressure drop being not discovered in time and thus the failure of the activated carbon adsorption device to be eliminated in time, the utility model provides an activated carbon adsorption device, which can realize timely sounding of an alarm when an abnormal pressure drop occurs, so as to timely eliminate the failure of the activated carbon adsorption device.

[0030] It should be noted that the activated carbon adsorption device described in the utility model is used for but not limited to waste gas purification, etc. For the convenience of explanation, in the utility model, only the application of the activated carbon adsorption device to waste gas purification is used as an example for explanation, and the principle of applying the activated carbon adsorption device to other types of equipment is essentially the same as the principle applied to the waste gas purification equipment, which will not be repeated here.

[0031] See also Figure 1 , Figure 1 Schematic diagram of the structure of an activated carbon adsorption device in one embodiment of the utility model. The activated carbon adsorption device includes a cylinder 1, an activated carbon layer 2 and an alarm mechanism 3.

[0032] The activated carbon layer 2 is disposed in the cylinder 1 and divides the inner cavity of the cylinder 1 into an air inlet cavity 11 and an air outlet cavity 12 .

[0033] See also Figure 1-Figure 3 The alarm mechanism 3 includes a connecting tube 31, a piston 32, an elastic member 33, a micro switch 34 and an alarm 35. The two ends of the connecting tube 31 are respectively connected to the air inlet chamber 11 and the air outlet chamber 12. The piston 32 is sealingly and slidably arranged in the connecting tube 31. The two ends of the elastic member 33 are respectively connected to the piston 32 and the connecting tube 31. The micro switch 34 is arranged in the connecting tube 31. When the piston 32 moves to a preset position, the contact of the micro switch 34 is pressed to cause the alarm 35 to sound an alarm.

[0034] When in use, the cylinder 1 is connected to the exhaust gas pipe, and the exhaust gas enters the air inlet chamber 11, enters the air outlet chamber 12 after being processed by the activated carbon layer 2, and is then discharged to the subsequent processing device. Due to the presence of the activated carbon layer 2, there will be a pressure difference between the air inlet chamber 11 and the air outlet chamber 12, thereby causing the piston 32 to move and compress the elastic member 33. When the restoring force provided by the elastic member 33 at a certain compression amount is balanced with the pressure difference between the air inlet chamber 11 and the air outlet chamber 12, the piston 32 no longer moves. If the pressure difference between the air inlet chamber 11 and the air outlet chamber 12 increases abnormally due to blockage of the activated carbon layer 2 or other reasons, the piston 32 continues to move in the direction of compressing the elastic member 33. When the piston 32 moves to a preset position (corresponding to a preset abnormal pressure difference), the contact of the microswitch 34 is pressed, so that the alarm 35 sounds an alarm, thereby reminding the staff to inspect the activated carbon adsorption device. Through this device, an alarm can be issued in time when an abnormal pressure drop occurs, so as to timely eliminate the fault of the activated carbon adsorption device.

[0035] In one embodiment, see Figure 1-Figure 3 The alarm mechanism 3 also includes an alarm power supply 36, and the micro switch 34, the alarm 35 and the alarm power supply 36 are connected in series to form a closed loop.

[0036] In one embodiment, see Figure 1-Figure 3 The micro switch 34 is a normally open micro switch. In this way, when the contact of the micro switch 34 is not pressed, the micro switch 34 is in an open state and the alarm 35 is powered off. When the contact of the micro switch 34 is pressed, the micro switch 34 is in a closed state and the alarm 35 is powered on to sound an alarm.

[0037] In one embodiment, see Figure 1 and Figure 2 The alarm mechanism 3 further includes a first fixing seat 37 and a guide rod 38. The first fixing seat 37 is fixed in the connecting tube 31. The first fixing seat 37 is provided with a first plug hole. The guide rod 38 is slidably inserted in the first plug hole. The guide rod 38 is fixedly connected with the piston 32. The elastic member 33 is a spring. The spring is sleeved on the guide rod 38. One end of the spring abuts against the piston 32, and the other end of the spring abuts against the first fixing seat 37. When in use, when the piston 32 is pushed by the airflow of the air inlet chamber 11, the guide rod 38 moves to the right and pushes the elastic member 33 to compress. By setting the guide rod 38, the movement of the piston 32 can be guided to improve the stability of its movement process.

[0038] In one embodiment, see Figure 1 and Figure 2The alarm mechanism 3 also includes a second fixed seat 39, which is fixed in the connecting tube 31. A second plug hole is provided on the second fixed seat 39, and the guide rod 38 is slidably inserted in the second plug hole. In this embodiment, the stability of the guide rod 38 during the movement process can be improved by adding a second fixed seat 39.

[0039] In one embodiment, see Figure 1 and Figure 2 The alarm mechanism 3 further includes a protrusion 381 , which is fixed on the guide rod 38 . When the piston 32 moves to a preset position, the contact of the micro switch 34 is pressed by the protrusion 381 .

[0040] In one embodiment, see Figure 1 The activated carbon layer 2 includes two first porous plates 21 and two second porous plates 22. The two first porous plates 21 are fixed in the cylinder 1, and a first filling space for filling a first filler 23 is formed between the two first porous plates 21. The two second porous plates 22 are fixed in the cylinder, and a second filling space for filling a second filler 24 is formed between the two second porous plates 22.

[0041] In one embodiment, see Figure 1 The first filler 23 is a Weibel ring filler, and the second filler 24 is a granular activated carbon filler.

[0042] In one embodiment, see Figure 1 The cylinder 1 is provided with a first material changing port 13 communicating with the first filling space, and a first cover plate 14 is detachably mounted on the first material changing port 13. The cylinder 1 is provided with a second material changing port 15 communicating with the second filling space, and a second cover plate 16 is detachably mounted on the second material changing port 15. Taking the replacement of the filler in the first filling space as an example, the first cover plate 14 is first opened, and all the first fillers 23 in the first filling space are taken out, and then new first fillers 23 are loaded into the first filling space, and then the first cover plate 14 is covered, so that the filler in the first filling space can be replaced.

[0043] In one embodiment, see Figure 1 The activated carbon adsorption device also includes a base 4, a feed connector 5 and a discharge connector 6, the feed connector 5 and the discharge connector 6 are respectively installed at both ends of the cylinder 1, and the feed connector 5 and the discharge connector 6 are both fixed to the base 4.

[0044] In order to better understand the present invention, the following Figures 1 to 3The technical solution of the utility model is described in detail: when in use, the cylinder 1 is connected to the exhaust gas pipeline, the exhaust gas enters the air inlet chamber 11, enters the air outlet chamber 12 after being processed by the activated carbon layer 2, and is then discharged to the subsequent processing device. Due to the presence of the activated carbon layer 2, there will be a pressure difference between the air inlet chamber 11 and the air outlet chamber 12, so that the piston 32 moves and compresses the elastic member 33. When the restoring force provided by the elastic member 33 at a certain compression amount is balanced with the pressure difference between the air inlet chamber 11 and the air outlet chamber 12, the piston 32 no longer moves. If the pressure difference between the air inlet chamber 11 and the air outlet chamber 12 increases abnormally due to blockage of the activated carbon layer 2 or other reasons, the piston 32 continues to move in the direction of compressing the elastic member 33. When the piston 32 moves to a preset position (corresponding to a preset abnormal pressure difference), the contact of the micro switch 34 is pressed, so that the alarm 35 sounds an alarm, thereby reminding the staff to repair the activated carbon adsorption device. Through this device, an alarm can be issued in time when an abnormal pressure drop occurs, so as to timely eliminate the fault of the activated carbon adsorption device.
