DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4 , a sound-absorbing box with purification function in the figure comprises a box 101 and a box cover 102 connected to one side of the box 101 by bolts, and the opposite two side walls of the box 101 are respectively provided with an air inlet pipe 103 and an air outlet pipe 104, further comprising a sound-absorbing assembly provided in the box 101 for absorbing noise and a purification assembly for purifying exhaust gas;

[0022] The sound-absorbing assembly comprises a rock wool sound absorption board 2 provided on the inner wall of the box 101, a glass fiber sound absorption felt 3 provided on the side of the rock wool sound absorption board 2 away from the inner wall of the box 101, and a non-woven fabric 4 provided on the side of the glass fiber sound absorption felt 3 away from the rock wool sound absorption board 2;

[0023] The purification assembly comprises a first filter plate 501, a second filter plate 502, an activated carbon adsorption plate 503 and a photocatalyst plate 504 provided in the box 101 in sequence, the first filter plate 501 is provided close to the air inlet pipe 103, and the pore size of the first filter plate 501 is larger than that of the second filter plate 502, and the box 101 is provided with a speed reduction assembly for reducing the speed of exhaust gas flow when the speed of exhaust gas flow is relatively high;

[0024] It should be noted that: the box cover 102 is also provided with a sound-absorbing assembly with the same structure.

[0025] It should be noted that: the box cover 102 is also provided with a sound-absorbing assembly with the same structure.

[0026] Please refer toFigure 2 and Figure 3 The two inner walls of the box 101 in the illustration are respectively provided with two ultraviolet lamps 505 arranged obliquely, and the two ultraviolet lamps 505 on the same side are symmetrically arranged with respect to the photocatalyst plate 504.

[0027] It should be noted that when the ultraviolet lamp 505 is arranged, when the ultraviolet light irradiates the photocatalyst plate 504, free radicals with strong oxidizing properties are generated, which can decompose harmful organic matter in the air and convert it into harmless gas.

[0028] It should be noted that the impurities and products generated during the purification process of the exhaust gas can be collected by installing a collection disc at the bottom of the purification assembly, and at the same time, after a period of use, the impurities can be concentrated and the purification assembly can be cleaned and replaced by opening the box cover 102.

[0029] Working principle: when the silencer box with purification function is used, first connect one end of the air inlet pipe 103 to the equipment exhaust port (it should be noted that the overall side wall of the air inlet pipe 103 is inside the box 101, so as to ensure the silencing effect during the exhaust process), and a fan can be installed at the air outlet pipe 104 to accelerate the exhaust of purified air, and the air outlet pipe 104 can also be connected to the ventilation duct to deliver the purified air to the designated location.

[0030] After the box 101 is installed, under the action of the exhaust pressure of the exhaust gas and the suction force of the fan, the exhaust gas flows from the air inlet pipe 103, and when the exhaust gas flows from the air inlet pipe 103, the impact of the high-speed flowing exhaust gas on the inner wall of the air inlet pipe 103 will generate noise, and when the noise is generated, the noise will be preliminarily reduced under the sound absorption effect of the glass fiber sound absorption felt 3, and then the porous structure of the rock wool sound absorption plate 2 is used to further absorb and scatter the sound wave, so as to convert the sound energy into heat energy and consume it, thereby realizing the noise reduction and silencing treatment during the exhaust process.

[0031] And in the process of exhaust emission, when the exhaust gas flows from the air deflector 9 to the box 101, the large particles of dust and other impurities in the exhaust gas will be filtered first by the hierarchical filtering effect of the first filter plate 501 and the second filter plate 502, then the activated carbon adsorption plate 503 is used to adsorb harmful gases and odors, and then the ultraviolet lamp 505 and the photocatalyst plate 504 (such as titanium dioxide) in the box 101 are set, when the ultraviolet light irradiates the photocatalyst plate 504, free radicals with strong oxidizing properties will be generated, these free radicals can decompose harmful organic matter in the air and convert it into harmless gas, thereby realizing the purification operation of the exhaust gas, and further, under the cooperation and integration of the noise reduction assembly and the purification assembly, the device quantity and installation space are reduced, and the cost of exhaust noise reduction and purification treatment is reduced.

[0032] Embodiment 2

[0033] Please refer to Figure 4 , the embodiment further illustrates embodiment 1, the speed reduction assembly in the figure includes a plurality of mounting boxes 601 fixedly connected to the air inlet pipe 103 inside the side wall of the box 101, each mounting box 601 is arranged in a ring array, each mounting box 601 is rotatably connected with a rotating rod 602, a plurality of fan blades 603 are fixedly connected to the inside side wall of each mounting box 601, a plurality of through holes 604 are formed in the side wall of the air inlet pipe 103, each through hole 604 is in communication with the mounting box 601, and each mounting box 601 is provided with a resistance adding assembly for applying resistance to the rotating rod 602;

[0034] It should be noted that: through the setting of the speed reduction assembly, the high-speed flowing exhaust gas in the air inlet pipe 103 blows the fan blades 603, so that the rotating rod 602 rotates, and then under the cooperation of the resistance adding assembly and the extrusion assembly, the rotating speed of the rotating rod 602 in the rotating process is limited, and then under the interaction of the resistance, the speed of the high-speed flowing exhaust gas in the air inlet pipe 103 is reduced, so that the exhaust gas passes through the noise reduction assembly and the purification assembly at a slower speed, thereby increasing the residence time of the exhaust gas in the noise reduction assembly and the purification assembly, and improving the noise reduction and purification effect of the exhaust gas.

[0035] It should be noted that: part of the side wall of the fan blade 603 will be inside the air inlet pipe 103 during rotation, so that the high-speed flowing exhaust gas in the air inlet pipe 103 can blow on the side wall of the fan blade 603.

[0036] Please refer to Figure 3 and Figure 4The resistance adding assembly in the drawing comprises a fixed plate 701 fixedly connected to one side of the mounting box 601, the fixed plate 701 is connected with an arc-shaped friction plate 702 through a pressing assembly, one end of a rotating rod 602 close to the arc-shaped friction plate 702 is fixedly connected with a friction ring 703, and the arc-shaped friction plate 702 is arranged in abutment with the friction ring 703 under the extrusion of the pressing assembly;

[0037] It should be noted that the resistance adding assembly is arranged to add resistance to the rotation of the rotating rod 602, thereby reducing the rotation speed of the fan blade 603.

[0038] Please refer to Figure 3 and Figure 4 The pressing assembly in the drawing comprises two T-shaped rods 801 symmetrically arranged and slidably connected to the fixed plate 701, one end of each of the two T-shaped rods 801 is connected with the arc-shaped friction plate 702, a spring 802 is sleeved on the side wall of each of the two T-shaped rods 801, and the two ends of each of the two springs 802 are connected with the fixed plate 701 and the arc-shaped friction plate 702 respectively.

[0039] It should be noted that the pressing assembly is arranged to push the arc-shaped friction plate 702 to always abut against the friction ring 703.

[0040] Embodiment 3

[0041] Please refer to Figure 4 The present embodiment is further illustrated in combination with other embodiments, and the air inlet pipe 103 is fixedly connected with a horn-shaped air deflector 9 at one end close to the first filter plate 501.

[0042] It should be noted that the horn-shaped air deflector 9 fixedly connected at one end of the air inlet pipe 103 close to the first filter plate 501 helps to increase the contact area of the exhaust gas and the purification assembly, thereby improving the purification effect of the exhaust gas, and meanwhile, the use efficiency of the purification assembly is improved.
