Description

Technical Field

[0001] The invention relates to the field of pyrolysis ion detection, and in particular to a micro front-end filtering system for pyrolysis ion detection. Background Art

[0002] With the rapid development of modern technology, the stable operation of equipment is crucial to key areas, especially in places such as data centers, subway facilities, and power cables. Once the equipment in these environments has abnormal conditions such as overheating, it may cause serious losses or even irreversible consequences. In order to provide timely warnings before problems occur, very early equipment overheating detection systems have come into being. They are designed to issue alarms hours before the equipment shows signs of overheating, so that maintenance personnel can quickly take measures to find and solve potential causes of overheating, thereby effectively avoiding equipment damage or system paralysis.

[0003] However, the current overheat detection system still has certain limitations in terms of accuracy and sensitivity. Large particles, dust and other impurities in the air can easily interfere with the accuracy of pyrolysis ion detection, resulting in false alarms or missed alarms. Traditional filtering structures are usually large in size and cannot meet the needs of miniaturized equipment. In addition, they have poor filtering effects on tiny particles smaller than 10 nanometers, making it difficult to ensure the purity of the gas entering the detection system. Therefore, it is necessary to propose a miniature front-end filtration system for pyrolysis ion detection that is compact and has better filtering effects. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a micro front-end filtering system for pyrolysis ion detection.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is: it includes a sealed box body, an air inlet and an air outlet are arranged on the box body, and a first partition and a second partition are arranged inside the box body; the first partition and the second partition divide the interior of the box body into a sedimentation chamber, a coarse filter chamber and a fine filter chamber in sequence, and the first partition and the second partition are both provided with air vents, the coarse filter chamber is filled with coarse filter material, and the fine filter chamber is filled with fine filter material; three vertical baffles are arranged on the top of the sedimentation chamber, and two human-shaped baffles are arranged at the bottom of the sedimentation chamber, and the vertical baffles and the human-shaped baffles are staggered.

[0006] Furthermore, a dust collecting port cooperating with the vertical baffle is arranged at the bottom of the sedimentation chamber, and a dust collecting box is arranged on the dust collecting port.

[0007] Furthermore, water boxes are arranged on both sides of the dust collecting port, and the water box is provided with an opening on one side cooperating with the dust collecting port, and a film is fixed on the opening.

[0008] Furthermore, a counterweight is arranged in the water box.

[0009] Furthermore, the air inlet and the air outlet are both arranged on the top side of the box body, and the air inlet, the air outlet and the vent are located at the same horizontal height.

[0010] Furthermore, the vertical baffle and the human-shaped baffle are both made of resin.

[0011] Further, the bottom of the vertical baffle is lower than the air inlet, and the bottom of the vertical baffle is higher than the top of the human-shaped baffle.

[0012] Furthermore, the height of the vertical baffle is greater than one-third of the height of the sedimentation chamber, and the height of the vertical baffle is less than one-half of the height of the sedimentation chamber; the top of the human-shaped baffle is located in the middle of the vertical baffle.

[0013] Furthermore, the coarse filter material is common non-woven fabric or coarse metal wire mesh.

[0014] Furthermore, the fine filter material is a polyamide membrane.

[0015] The beneficial effects of the present invention are:

[0016] The present invention can effectively remove most of the particulate matter in the air, especially particles smaller than 10 nanometers, by integrating multi-stage filtration methods such as sedimentation structure, coarse filtration and fine filtration, so that the gas entering the pyrolysis ion detection system is purer; it not only improves the accuracy and reliability of overheat detection, but also meets the trend of modern equipment towards miniaturization, and has broad application prospects.

[0017] The multi-stage filtration strategy of the present invention ensures the purity of the gas entering the detection system and reduces the interference of impurities on pyrolysis ion detection. The filtered gas is mainly composed of pyrolysis ions, which significantly improves the sensitivity and accuracy of the very early equipment overheating detection system. The pure gas environment enables the sensor to more accurately capture the weak signals generated by equipment overheating, timely warn of potential risks, and greatly improve the detection accuracy.

[0018] The structure of the present invention is exquisitely designed and small in size, which is suitable for integration and installation of miniaturized systems. Compared with traditional filtering devices, it occupies less space and is easy to deploy inside equipment or in space-constrained environments. Due to the efficient removal of large particles by the filtering structure, the clogging frequency of the filter is reduced, the service life of the equipment is extended, and the daily maintenance and replacement costs are reduced. The innovative human-shaped baffle and vertical baffle layout effectively guide the airflow, improve the sedimentation and capture efficiency of particles, and further improve the filtering effect.

For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0028] like Figure 1 , 2 As shown in FIGS. 3 and 4 , the micro front-end filtration system for pyrolysis ion detection includes a sealed box 18, the length of the box 18 is preferably 40 mm, the height is preferably 20 mm, and the width is preferably 10 mm. The box 18 is provided with an air inlet 2 and an air outlet 12, and the inside of the box 18 is provided with a first partition 15 and a second partition 16.

[0029] The first partition 15 and the second partition 16 divide the interior of the box body 18 into a sedimentation chamber 1, a coarse filter chamber 8 and a fine filter chamber 10 in sequence. Vent holes 17 are provided on the first partition 15 and the second partition 16. The coarse filter chamber 8 is filled with coarse filter material 9, and the fine filter chamber 10 is filled with fine filter material 11.

[0030] Three vertical baffles 13 are arranged at the top of the sedimentation chamber 1, and two human-shaped baffles 3 are arranged at the bottom of the sedimentation chamber 1. The vertical baffles 13 and the human-shaped baffles 3 are arranged in a staggered manner. The vertical baffles 13 and the human-shaped baffles 3 are both made of resin. The bottom of the vertical baffle 13 is lower than the air inlet 2, and the bottom of the vertical baffle 13 is higher than the top of the human-shaped baffle 3. The height of the vertical baffle 13 is greater than one-third of the height of the sedimentation chamber 1, and the height of the vertical baffle 13 is less than one-half of the height of the sedimentation chamber 1. The top of the human-shaped baffle 3 is located in the middle of the vertical baffle 13.

[0031] like Figure 1 , 5 As shown in Figure 6, a dust collecting port 14 cooperating with the vertical baffle 13 is provided at the bottom of the sedimentation chamber 1, and a dust collecting box 7 is provided on the dust collecting port 14. Water boxes 5 are provided on both sides of the dust collecting port 14, and the water box 5 is provided with an opening on one side cooperating with the dust collecting port 14, and a film 4 is fixed on the opening. Water vapor is generated by the film 4 so that large particles such as dust particles are better absorbed in the dust box 7. The dust box 7 can be taken out from the dust collecting port 14, which is convenient for cleaning and replacement of the dust box 7.

[0032] In this embodiment, a counterweight 6 is provided in the water box 5, and the counterweight 6 enables the direction of the water box 5 to maintain a correct direction.

[0033] In this embodiment, the air inlet 2 and the air outlet 12 are both arranged on the top side of the box body 18, and the air inlet 2, the air outlet 12 and the vent hole 17 are located at the same level.

[0034] In this embodiment, the coarse filter material 9 is a common non-woven fabric or a coarse metal wire mesh, which is used to filter large particles of 5-200 um.

[0035] In this embodiment, the fine filter material 11 is a polyamide membrane, which is used to filter particles of 0.01-5 um.

[0036] The micro front-end filtration system for pyrolysis ion detection of the present invention can effectively remove most of the particulate matter in the air, especially particles smaller than 10 nanometers, by integrating multi-stage filtration methods such as sedimentation structure, coarse filtration and fine filtration, so that the gas entering the pyrolysis ion detection system is purer. This not only improves the accuracy and reliability of overheat detection, but also meets the trend of modern equipment towards miniaturization.

[0037] Working process and principle: the detection gas enters the sedimentation chamber 1 through the air inlet 2. Under the action of the human-shaped baffle 3 and the vertical baffle 13, the large particles in the detection gas are combined with the water vapor generated by the water box 5 and the film 4 and deposited in the dust collecting box 7. The remaining detection gas enters the coarse filter chamber 8. The coarse filter material 9 filters out the coarse particles of 5-200um in the remaining detection gas. The remaining residual detection gas enters the fine filter chamber 10. The fine filter material 11 filters out the fine particles of 0.01-5um in the remaining residual detection gas. Finally, the detection gas after three-stage filtration is discharged from the air outlet 12 and enters the detection system. The gas after three-stage filtration ensures the purity of the gas entering the detection system and reduces the interference of impurities on the detection of pyrolysis ions. The filtered gas is mainly composed of pyrolysis ions, which significantly improves the sensitivity and accuracy of the very early equipment overheating detection system. The pure gas environment enables the sensor to more accurately capture the weak signals generated by equipment overheating, timely warn of potential risks, and can greatly improve the detection accuracy.

It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
