Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to a triple-filtering jet dehumidification unit. Background Art

[0002] Underground construction sites, such as tunnels, generate large amounts of dust, harmful gases, and pathogens. The resulting poor air quality severely impacts the physical and mental health of construction workers and significantly reduces work efficiency. Traditional forced-in ventilation only dilutes the air but fails to filter or purify it.

[0003] In the prior art, for example, Chinese patent CN114396683A published on 2022-04-26 discloses a fresh air dehumidification air purifier, which filters the fresh air entering the fresh air inlet 210 through a primary filter and a high-efficiency filter in sequence, and then condenses and dehumidifies it through a condenser, thereby achieving the function of filtering and dehumidifying the air.

[0004] However, in this type of prior art, only dust removal and filtration can be performed through the filter screen, and various harmful gases, pathogens, viruses, etc. cannot be purified. Utility Model Content

[0005] The purpose of this utility model is to provide a triple-filter jet dehumidifier unit that can dehumidify the air and purify various harmful gases, bacteria and viruses.

[0006] The utility model provides a triple-filtering jet dehumidifier, comprising a dehumidifier body, wherein the air inlet of the dehumidifier body is provided with a dust filter, and a chemical filter and an antibacterial and antiviral fiber layer are sequentially provided in the air flow path of the dehumidifier body; and the air outlet of the dehumidifier body is provided with a jet nozzle.

[0007] Furthermore, the dust filter is arranged on one side of the bottom of the dehumidification unit body.

[0008] Furthermore, the jet nozzle is arranged on one side of the top of the dehumidification unit body.

[0009] Furthermore, the chemical filter is a hollow tower structure.

[0010] Furthermore, the tip of the chemical filter faces the antibacterial and antiviral fiber layer.

[0011] Furthermore, at least one side surface of the chemical filter faces the dust filter.

[0012] Furthermore, the antibacterial and antiviral fiber layer is located on top of the chemical filter.

[0013] Furthermore, the dehumidification unit body includes a fan, and the fan is located on the top of the antibacterial and antiviral fiber layer.

[0014] Furthermore, the dehumidification unit body includes a ring-shaped condenser, and the fan is arranged in the condenser.

[0015] Furthermore, the jet nozzle is arranged above the fan and the condenser and is connected to the fan.

[0016] The technical solution of this utility model achieves primary and secondary dust removal and filtration by installing a dust filter at the air inlet of the dehumidifier unit. After the bad air enters the dehumidifier unit through the dust filter, it then passes through a chemical filter, which uses chemical adsorption to chemically adsorb various harmful gases generated on the work surface, chemically decomposing the harmful gases into harmless gases. The bad air then passes through the antibacterial and antiviral fiber layer, which kills pathogens and viruses and purifies the air. Thus, this utility model can filter and purify dust, various harmful gases, and pathogens and viruses generated on the construction work surface, ensuring that the air quality on the work surface meets requirements, protecting the physical and mental health of construction workers, and improving construction efficiency.

[0025] Example 1

[0026] like Figure 1-Figure 2 As shown, the utility model provides a triple-filtering jet dehumidification unit, including a dehumidification unit body, the air inlet of the dehumidification unit body is provided with a dust filter 9, and the air flow path of the dehumidification unit body is sequentially provided with a chemical filter 10 and an antibacterial and antiviral fiber layer 12; the air outlet of the dehumidification unit body is provided with a jet nozzle 1.

[0027] Specifically, the dehumidification unit body can directly adopt the dehumidification unit device in the existing technology, and its structure is not described in detail. In this embodiment, the bad air entering the dehumidification unit body is mainly subjected to a triple purification process of dust filtration section, chemical filtration section and antibacterial and antiviral filtration section.

[0028] Among them, the dust filtering section is a conventional primary and secondary efficiency filter, such as a dust filter net, which is mainly used to filter various dusts generated on the working surface.

[0029] The chemical filter 10 is filled with chemical filter media, such as activated carbon, and uses the principle of chemical adsorption to chemically adsorb various harmful gases generated on the working surface and chemically decompose the harmful gases into harmless gases.

[0030] The antibacterial and antiviral fiber layer 12 is composed of antibacterial and antiviral fibers, such as medical antibacterial cloth, antibacterial non-woven fabric, etc., and sterilizes and disinfects through the metal silver ion antibacterial agent added therein, and utilizes the disinfecting effect of the fiber layer on pathogens and viruses to purify the air.

[0031] The purified air after the above-mentioned triple purification process, after the dehumidification process of the dehumidifier unit itself, is ejected from the jet nozzle 1 in the form of a jet. The jet control air field theory of the working surface is used to comprehensively improve the air quality of the construction working surface, protect the physical and mental health of the construction workers, and improve the construction efficiency.

[0032] Example 2

[0033] The dust filter 9 is arranged on one side of the bottom of the dehumidification unit body. The jet nozzle 1 is arranged on one side of the top of the dehumidification unit body.

[0034] Specifically, in this device, the bad air flows from bottom to top through the purification process, better absorbs the bad air settled in the bottom space of the work surface, and maximizes the use of gravity to remove dust. The purified air is ejected from the top jet nozzle 1.

[0035] Example 3

[0036] The chemical filter 10 is a hollow tower structure. The top of the chemical filter 10 faces the antibacterial and antiviral fiber layer 12. At least one side of the chemical filter 10 faces the dust filter 9. The antibacterial and antiviral fiber layer 12 is located on the top of the chemical filter 10.

[0037] Specifically, in this device, by designing the chemical filter 10 as a hollow tower structure, both the inner and outer surfaces of the chemical filter 10 can come into contact with the bad air passing through the dust filter 9, thereby increasing the contact area between the bad air and the chemical filter 10 and improving the purification efficiency. The dust filter 9 is located on the bottom side of the chemical filter 10. When the bad air passing through the dust filter 9 enters the chemical filter 10, it first enters the bottom of the chemical filter 10, then passes upward through the chemical filter 10, and finally enters the antibacterial and antiviral fiber layer 12 after passing through the top of the tower for the next stage of purification. The antibacterial and antiviral fiber layer 12 separates the chamber where the chemical filter 10 is located from the chamber where the dehumidifier fan 2 is located. Through the negative pressure suction of the fan 2, the bad air is continuously sucked in and passes through the triple filtration stage.

[0038] Example 4

[0039] The dehumidifier unit includes an EC DC variable-speed fan 2, which is located on top of the antibacterial and antiviral fiber layer 12. The dehumidifier unit includes an annular condenser 6, with the fan 2 disposed within the condenser 6. The jet nozzle 1 is disposed above the fan 2 and the condenser 6 and is in communication with the fan 2.

[0040] Specifically, the dehumidification unit body includes a shell, a fan 2 is arranged in the middle of the shell, an evaporator 5 with an annular structure is provided on the outside of the fan 2, a condenser 6 with an annular structure is provided on the outside of the evaporator 5, and a chamber is provided at the lower part of the shell, which is located outside the chemical filter 10 and separated. The chamber is located below the condenser 6 and is provided with a liquid reservoir 7 and a digital scroll compressor 11 inside for storing the condensate of the condenser 6. An electric control box 8 is also provided in the shell, which is arranged at the lower part of one side of the shell. Its control panel is exposed outside the shell and can be manually operated. The electric control box 8 and the shell are sealed and waterproof. A silencer static pressure box 3 is provided above the fan 2 in the upper part of the shell. The silencer static pressure box 3 is covered with a centrifugal glass fiber + porous panel silencer layer 4. A plurality of jet nozzles 1 are arranged around the upper part of the shell. The purified and dehumidified air is silenced and then ejected toward the working surface by the jet nozzle 1.

[0041] The dust filter 9 is arranged at the lower part of one side of the shell, the chemical filter 10 is arranged at the lower part of one side inside the shell, and the antibacterial and antiviral fiber layer 12 is arranged between the connecting port of the chemical filter 10 chamber and the fan 2 chamber in the shell.

[0042] Working mode of this utility model:

[0043] This triple-filter jet dehumidifier unit changes the traditional forced-in ventilation model, incorporating the concept of "distributed centralized treatment and jet environmental control." It utilizes a triple filtration stage to purify and dehumidify dust, harmful gases, and pathogens and viruses generated on the construction work surface. Moist, contaminated construction waste gas from the work surface passes through dust filter 9, chemical filter 10, and antibacterial and antiviral fiber layer 12 before being drawn into the unit by EC DC variable-speed fan 2. The purified, moist air is dehumidified by evaporator 5 and condenser 6 before being forced into silencer static pressure chamber 3. After being silenced, the clean, dry air is ejected from jet nozzle 1 onto the work surface, covering, controlling, and improving the air quality. This air removes the moist, contaminated construction waste gas from the work surface before being drawn back into the unit through dust filter 9 for recirculation.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
