Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel dust removal, in particular to an intelligent tunnel air purification system. Background Art
[0002] During the driving process, the wheels rub against the road surface, the impurities outside the tunnel are brought in by the vehicle, and the harmful gases such as automobile exhaust, carbon monoxide, and sulfur dioxide are generated during the driving process, which causes an increase in dust in the tunnel. A large amount of dust in the tunnel will interfere with the driver's vision, making the visibility of the tunnel environment, which is already poor, even lower; secondly, the dust can easily enter the equipment in the tunnel, causing equipment abnormalities or failures, causing great safety hazards, and at the same time increasing the frequency of maintenance. Maintenance in the tunnel will interfere with the tunnel's traffic, further increasing safety hazards. Therefore, in the prior art, an air purification device is installed in the tunnel to purify the air in the tunnel and collect and uniformly treat the dust in the air.
[0003] At present, electrostatic dust removal is mainly used in tunnels. The dust is charged by the discharge stage. The dust collecting plate is set with the opposite charge to the dust. The dust moves toward the dust collecting plate under the action of the charge and adheres to the dust collecting plate to collect the dust. Then the dust cake on the dust collecting plate is cleaned and collected by the cleaning mechanism. However, in actual applications, due to changes in the traffic volume in the tunnel and the influence of external weather, the amount of dust in the tunnel is different. Since the dust removal function of the air purification device is single, when there is a lot of dust in the air, it is easy for the dust collecting plate to be unable to absorb dust before cleaning, resulting in the air purification device being unable to clean the air in the tunnel. Utility Model Content
[0004] The utility model aims to provide an intelligent tunnel air purification system, which can increase the adsorption capacity of dust in the tunnel and enhance the air purification effect.
[0005] The utility model provides the following basic solutions:
[0006] A tunnel air purification intelligent system comprises a sterilizer, a first dust collector and a second dust collector which are arranged in sequence. The sterilizer, the first dust collector and the second dust collector are detachably connected to each other, and the first dust collector and the second dust collector have different structures.
[0007] Further, the first dust collector includes a first body, and a dust collecting body and a discharge frame arranged in the first body, the dust collecting body includes two parallel supporting plates, the two supporting plates are provided with oppositely arranged through holes, a connecting pipe is provided between the two supporting plates, and both ends of the connecting pipe are respectively connected to the through holes on the two supporting plates;
[0008] The discharge rack includes a main bracket and discharge needles connected to the main bracket. The main bracket is located at one end of the dust collector body, and the free ends of the discharge needles pass through a support plate and are located inside the connecting pipe.
[0009] Furthermore, the dust collector body and the discharge rack are detachably connected to the first body together.
[0010] Furthermore, the first dust collector further includes a uniform air net provided inside the first body, and the uniform air net is slidably connected to the first body.
[0011] Furthermore, a plurality of groups of guiding members are provided on the inner wall of the first body. One group of guiding members includes two parallel guiding ridges, and the length direction of the guiding ridges is perpendicular to the length direction of the first body. The top and bottom of the uniform air net are respectively located between two guiding ridges of different groups.
[0012] Furthermore, the second dust collector includes a second body, and discharge plates and dust collecting plates provided inside the second body.

In this solution, a variety of structures are used to purify the tunnel air, improving the air purification effect. The structures of the first dust collector and the second dust collector are different. When the air purification effect of the first dust collector is not good, the second dust collector can make up for it, further improving the air purification effect of the air purification system. The detachable setting makes the sterilizer, the first dust collector, and the second dust collector modular, and they can be replaced according to the scenario and usage requirements. For example, multiple first dust collectors can be assembled.

The first dust collector and the second dust collector collect the dust and impurities in the tunnel through different structures, improving the adsorption amount of the tunnel dust by the air purification system.
[0020] 3. The dust collecting body and the discharge rack are both detachably connected to the first body.

By cleaning the dust collecting body and the dust collecting plate, the adsorbed dust is removed, so as to ensure the subsequent adsorption effect of the dust collecting body and the dust collecting plate on the dust, and thus ensure the air purification effect of the air purification system.

[0026] An intelligent tunnel air purification system, as shown in the attached Figure 1 figures, includes a sterilizer 1, a first dust collector 2, and a second dust collector 3 arranged in sequence. The structures of the first dust collector 2 and the second dust collector 3 are different. Specifically:
[0027] As shown in the appended Figure 2 、 3 figures, the first dust collector 2 includes a first body, and a uniform air distribution grid 4, a dust collecting body, and a discharge rack 5 disposed inside the first body. Both ends of the first body are communicated to form a passage for air to pass through, and the dust collecting body and the discharge rack 5 are located in the passage. An opening is provided on one side of the first body, and a baffle 9 is hinged to the opening.
[0028] The uniform air distribution grid 4 is slidably connected to the first body. Specifically, a plurality of groups of guiding members are provided on the inner wall of the first body. One group of guiding members includes two parallel guiding ridges, and the length direction of the guiding ridges is perpendicular to the direction of air passage (i.e., the length direction of the first body). In this embodiment, the number of guiding members is two groups, which are respectively located at the top and bottom inside the first body. The top and bottom of the uniform air distribution grid 4 are respectively located between two guiding ridges of different groups. The uniform air distribution grid 4 is limited by the two parallel guiding ridges, so that the uniform air distribution grid 4 slides between the two guiding ridges of the same group, and the uniform air distribution grid 4 can be taken out from the opening for cleaning or replacement.
[0029] The dust collecting body includes two parallel support plates 6, the support plates 6 are perpendicular to the length direction of the first body, and a plurality of opposite through holes are provided on the two support plates 6. A connecting pipe 7 is provided between the two support plates 6, and both ends of the connecting pipe 7 are respectively connected to the through holes on the two support plates 6. In this embodiment, the support plates 6 and the connecting pipe 7 are welded.
[0030] The discharge rack 5 includes a main bracket and discharge needles connected to the main bracket. The main bracket includes two parallel cross bars and a plurality of parallel vertical bars, and both ends of the vertical bars are respectively connected to the two cross bars. In this embodiment, the vertical bars, the cross bars and the discharge needles are welded. The main bracket is located at one end of the dust collecting body, and an insulator is installed on the side of the main bracket facing the dust collecting body. The end of the insulator away from the main bracket abuts against the dust collecting body. In this embodiment, the insulator is connected to the main bracket by bolts. The free end of the discharge needle passes through a support plate 6 and is located inside the connecting pipe 7. The number of discharge needles is the same as that of the connecting pipe 7 and they correspond one by one. The setting of the discharge rack 5 makes the dust and impurities in the air charged, so as to be adsorbed on the dust collecting body, realizing the collection of dust and impurities.
[0031] The dust collecting body and the discharge rack 5 are detachably connected to the first body together. Specifically, limiting ridges are provided at the bottom inside the first body. The number of the limiting ridges is two and they are arranged in parallel. The length direction of the limiting ridges is perpendicular to the length direction of the first body. When the dust collecting body and the discharge rack 5 are located inside the first body, one limiting ridge is located between the main bracket and the support plate 6, and the other limiting ridge is located between the two support plates 6. During use, the arrangement of the limiting ridges limits the dust collecting body and the discharge rack 5. When it is necessary to disassemble the dust collecting body and the discharge rack 5, lift it gently from the opening of the first body and move it towards the opening direction, so as to take out the dust collecting body and the discharge rack 5 for cleaning, maintenance or replacement.
[0032] The second dust collector 3 includes a second body, as well as discharge plates and dust collecting plates provided inside the second body. The two ends of the second body are communicated to form a passage for air to pass through. The discharge plates and the dust collecting plates are located inside the passage. The discharge plates and the dust collecting plates are both parallel to the length direction of the second body, and the discharge plates and the dust collecting plates are arranged alternately. The discharge plates and the dust collecting plates adopt the existing plate type electrostatic precipitator. Another opening is provided on one side of the second body, and another baffle 9 is hinged to the opening. The plate type electrostatic precipitator can be taken out from the opening for maintenance or replacement.
[0033] Both the first dust collector 2 and the second dust collector 3 are electrostatic precipitations. The principle of ionizing dust is a very mature existing technology, so it will not be elaborated here.
[0034] The sterilizer 1 includes a sterilization body, as well as an ultraviolet lamp 8 provided inside the sterilization body. The two ends of the sterilization body are communicated to form a passage for air to pass through. The ultraviolet lamp 8 is installed at the top inside the sterilization body. In this embodiment, the ultraviolet lamp 8 adopts the existing ultraviolet lamp tube, and the ultraviolet lamp 8 is installed inside the sterilization body through screws. The sterilizer 1 is used to kill bacteria in the air.
[0035] The sterilizer 1, the first dust collector 2 and the second dust collector 3 are detachably connected. Specifically, the sterilization body, the first body and the second body are detachably connected by bolts. Unilateral pressing blocks are provided on the first body and the second body, and the unilateral pressing blocks are used to open and close the baffle 9.
[0036] The sterilization body, the first body and the second body are communicated in sequence. A pre-filter screen 10 is provided at one end of the sterilization body away from the first body. The pre-filter screen 10 is perpendicular to the length direction of the sterilization body. In this embodiment, the pre-filter screen 10 is detachably connected inside the sterilization body through screws. The pre-filter screen 10 is used to filter large particle size dust, so as to reduce the large particle size dust entering the first dust collector 2 and the second dust collector 3 subsequently, thereby reducing the large particle size dust adsorbed in the first dust collector 2 and the second dust collector 3, reducing the interference of the large particle size dust on the adsorption of small particle size dust, and improving the adsorption effect on the small particle size dust.
[0037] One end of the second body away from the first body is connected with a ventilation duct 11, and a fan is arranged in the ventilation duct 11. In this embodiment, the ventilation duct 11 is connected to the second body by screws, and the fan is installed in the ventilation duct 11 by screws. The end face area of the ventilation duct 11 is smaller than the end face areas of the sterilization body, the first body and the second body, that is, from the second body to the ventilation duct 11, the aperture shrinks. Thus, the air is centrally conveyed, the air flow rate is increased, and the air purification effect is improved. Embodiment
[0038] The difference from the first embodiment is that: in a tunnel air purification intelligent system, the top of the plate-type electrostatic precipitator is open, and a spray head is arranged at the top inside the second body, and the spray head faces the plate-type electrostatic precipitator. The spray head is used to spray the dust collecting plate to realize automatic cleaning of the dust collecting plate. The bottom of the plate-type electrostatic precipitator is open, the bottom of the second body is open, and a drain port is arranged at the bottom of the second dust collector 3. The sewage after spraying is discharged from the bottom opening of the plate-type electrostatic precipitator, the bottom opening of the second body, and from the drain port. To realize the spraying function of the scheme, the second dust collector 3 is also provided with structures such as a water pipe and a water storage tank communicated with the spray head. The corresponding structures are existing spraying structures, which are very mature existing technologies, and those skilled in the art can install and set them according to the actual situation, so they will not be elaborated here.

It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
