Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of formaldehyde removal, and more specifically, to an integrated device for formaldehyde concentration monitoring and absorption. Background Technique
[0002] The synthesis of pyridine can be achieved by various methods. One of the classical routes is the reaction of acetaldehyde, formaldehyde, and ammonia under high temperature and high pressure. During the synthesis of pyridine, formaldehyde may overflow. Currently, when monitoring the formaldehyde concentration in the environment, the monitoring range is small, and the usage function is relatively single. While conducting real-time monitoring, it cannot effectively purify the air in the environment, affecting people's use.
[0003] The Chinese patent with the publication number CN216082648U discloses a formaldehyde monitoring device with an alarm function. Through a rotating mechanism, the suction hood connected to the intake elbow connected to the lifting plate can reciprocally lift, and at the same time, the rotating plate can rotate on the top of the moving base through an annular slider, thereby expanding the range of air extraction by the suction hood and making the monitoring range of this device wider and the monitoring effect better. However, the structure of this patent is complex, the size is relatively large, the discharged gas moves upward, which is not conducive to the dilution of formaldehyde in the environment. Moreover, the relative density of formaldehyde gas is 1.067, slightly greater than the air density, so it has a tendency to sink in indoor air and cannot be specifically absorbed.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.
[0021] Combined with Figures 1-4 , in this embodiment, the integrated formaldehyde concentration monitoring and absorption device includes an intake cylinder 1, an absorption cylinder 2, and an exhaust cylinder 3 connected in sequence from bottom to top. A rotating rod 4 is commonly connected in the intake cylinder 1, the absorption cylinder 2, and the exhaust cylinder 3. A partition plate 11 is provided in the intake cylinder 1. The partition plate 11 divides the intake cylinder 1 into an intake chamber and an exhaust chamber. An intake pipe 12 is connected to the partition plate 11. The intake pipe 12 communicates with the intake chamber. An air vent 111 is opened on the partition plate 11. An intake port 13 is opened at the lower end of the intake chamber. A dust-proof net is provided on the intake port 13. External gas is inhaled into the intake chamber through the intake pipe 12 and the intake port 13 at the same time, and enters the absorption cylinder 2 through the exhaust chamber. An exhaust pipe 14 is fixedly connected to the upper end of the exhaust chamber. The exhaust pipe 14 penetrates through the absorption cylinder 2, and the end of the exhaust pipe 14 is placed below the formaldehyde absorption liquid in the absorption cylinder 2. The exhaust pipe 14 discharges the absorbed formaldehyde-containing gas into the formaldehyde absorption liquid. After the formaldehyde is absorbed by the formaldehyde absorption liquid, the clean gas overflows from above the formaldehyde absorption liquid and enters the absorption cylinder 2.
[0022] In this embodiment, formaldehyde sensors 15 are provided on the side wall of the intake cylinder 1 and the inside of the intake pipe 12. The separately arranged formaldehyde sensors 15 can detect the formaldehyde content at different heights. When any one of the formaldehyde sensors 15 detects that the formaldehyde content exceeds the standard, the formaldehyde absorption function is activated.
[0023] In this embodiment, the absorption cylinder 2 is filled with formaldehyde absorption liquid, and a filter filler 21 is provided above the formaldehyde absorption liquid. The filter filler 21 is used to absorb and remove other impurities in the gas after formaldehyde is absorbed, playing a role in purifying the air.
[0024] In this embodiment, a driving motor 41 is connected to the rotating rod 4 at the position in the intake chamber. The upper end of the rotating rod 4 is movably connected to the top of the exhaust pipe 3 through a bearing. The driving motor 41 controls the rotation of the rotating rod 4, and the exhaust pipe 3 can stabilize the upper end of the rotating rod 4. A first fan blade 42 is connected to the rotating rod 4 at the position in the exhaust chamber, and a second fan blade 43 is connected to the rotating rod 4 at the position above the filtering filler 21 in the absorption cylinder 2. The rotating rod 4 drives the first fan blade 42 and the second fan blade 43 to rotate synchronously. The first fan blade 42 generates negative pressure in the exhaust chamber to suck air into the intake chamber, and the second fan blade 43 blows the treated air towards the exhaust pipe 3.
[0025] In this embodiment, a ventilation opening 22 is provided at the upper end of the absorption cylinder 2, and a mounting ring 23 is provided on the ventilation opening 22. The mounting ring 23 is movably connected to the exhaust pipe 3. The treated gas is introduced into the exhaust pipe 3 through the ventilation opening 22, and the exhaust pipe 3 can rotate through the mounting ring 23.
[0026] In this embodiment, a mounting sleeve 31 is provided at the lower end of the exhaust pipe 3. The mounting sleeve 31 is sleeved with the mounting ring 23. A discharge pipe 32 is provided on the side wall of the exhaust pipe 3. The discharge pipes 32 are distributed on the side wall of the exhaust pipe 3 at equal distances in a circular shape, and the center line of the discharge pipe 32 is not the diameter line of the exhaust pipe 3. The gas discharged from the discharge pipe 32, under the action of air pressure, pushes the exhaust pipe 3 to rotate. The rotating exhaust pipe 3 can evenly disperse the treated gas into the environment, and at the same time stir the gas in the environment, which can accelerate the gas flow in this area, thereby realizing the dilution of formaldehyde in the environment.
[0027] Working process: Two formaldehyde sensors 15 simultaneously detect the formaldehyde content in the space. When any one of the formaldehyde sensors 15 detects that the formaldehyde content exceeds the standard, the formaldehyde absorption function is activated. The driving motor 41 controls the rotation of the rotating rod 4, driving the first fan blade 42 and the second fan blade 43 to rotate. The air inlet 13 and the intake pipe 12 intake air into the intake cylinder 1, and the gas is input into the formaldehyde absorption liquid in the absorption cylinder 2 through the exhaust pipe 14. The gas after removing formaldehyde overflows from the formaldehyde absorption liquid, is filtered by the filtering filler 21, enters the exhaust pipe 3, and is discharged from the discharge pipe 32. The discharged gas pushes the exhaust pipe 3 to rotate, evenly distributing the clean gas and diluting the formaldehyde content in the environment.
[0028] In summary: An integrated device for formaldehyde concentration monitoring and absorption of the present utility model completes the functions of air intake, absorption, and exhaust through the intake cylinder 1, absorption cylinder 2, and exhaust pipe 3 connected in sequence from bottom to top. The exhaust uses air pressure to promote the rotation of the exhaust pipe 3, which can evenly distribute the clean gas, stir the gas flow in the environment, quickly dilute the formaldehyde in the environment, has a simple structure, is provided with an intake pipe 12 and an air inlet 13, can absorb gases at different heights, and particularly places the air inlet 13 at a low position, which is beneficial to absorbing the sedimented formaldehyde.
