Description

Technical Field

[0001] The disclosed embodiments relate to the technical field of fume purification equipment, and in particular to a downward-sinking fume purification device. Background Art

[0002] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present disclosure, and shall not necessarily be regarded as an admission or any form of suggestion that the information constitutes the relevant technology that has been known to ordinary technicians in the field.

[0003] In the related art, smoke purification equipment generally adopts straight-through exhaust filtration, which is more common in air purification applications. Generally, the purpose of air purification is achieved by eliminating particulate matter and odor in the air through a filter layer and chemical methods. However, in view of industry characteristics, such as in the process of electronic welding, a large amount of condensable smoke containing rosin is generated. The straight-through filter structure has limited space, and the density of condensable particles increases after the smoke enters, which is easy to condense quickly. After a period of use, a large amount of condensation occurs at the air inlet, but the filter part has not reached a saturated state, resulting in the need to frequently clean the pipeline, increasing the workload and affecting work efficiency, and reducing the service life of the pipeline;

[0004] More importantly, in order to increase the purification space of traditional flue gas purification equipment, the size of the equipment increases accordingly, and the flue gas path is too long, which results in greater resistance during the purification process, increases the pressure on the fan, and reduces the fan efficiency.

[0028] The following is a description of the implementation methods of the present disclosure by specific specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

[0029] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present disclosure. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present disclosure without substantially changing the technical content.

[0030] like Figure 1-5 As shown, it shows a sinking smoke purification device of an exemplary embodiment of the present disclosure. It includes a main body 1 composed of an air intake area, a purification area and a discharge area. The air intake area includes an air inlet 2 arranged at the bottom of the main body 1, and the air inlet 2 is connected to a sinking air intake cavity 3 inside the main body 1; the purification area includes a filter assembly located in the middle of the main body 1, and a fan 4 is provided at the bottom of the filter assembly; the discharge area includes an exhaust cavity 5 located in a side area of ​​the filter assembly, and the exhaust cavity 5 is connected to an exhaust port 6 located at the top of the main body 1; wherein the sinking air intake cavity 3 is connected to the top space of the filter assembly through a sinking air inlet channel 7, and the sinking air inlet channel 7 surrounds the three side areas of the filter assembly.

[0031] It adopts a downward air intake method, and the smoke flows in the reverse direction through the downward air intake channel 7 for filtration, which can reduce the center height of the equipment and improve the stability of the equipment operation. The downward air intake channel 7 can significantly save space, shorten the smoke flow path, reduce the resistance during the smoke movement, and improve the efficiency of the fan 4.

[0032] See also Figure 4As shown, since the downward-sunken air inlet channel 7 is arranged on three sides of the purification device to utilize less space, the air inlet 2 is located on one side of the main body 1. In order to enable the smoke to quickly enter the downward-sunken air inlet channel 7 farther away from the other two intersecting air inlets to increase the ventilation volume, the air inlet is connected to the downward-sunken air inlet channels 7 on two adjacent sides through an internal connecting pipe 8 to form a U-shaped structure. A downward-sunken air inlet channel 7 is opened between the downward-sunken air inlet cavity 3 of the U-shaped structure and the purification area. The downward-sunken air inlet channel 7 is provided with a breathable smoke hood 9 on one side of the inspection door 18 to facilitate the replacement of the filter. The U-shaped downward-sunken air inlet cavity 3 draws the smoke into the filter assembly evenly and quickly through the opened downward-sunken air inlet channel 7. At the same time, a breathable smoke hood 9 is provided on the sunken air inlet channel 7. The breathable smoke hood 9 is a partition with a porous structure, which can moderate the flow rate of flue gas while intercepting a part of solid particles in the flue gas, thereby increasing and reducing the pressure of the purification component. The inspection door 18 arranged on the side of the main body 1 corresponds to the position of the breathable smoke hood 9, so it can be cleaned at any time.

[0033] Among them, the breathable smoke hood 9 is arranged on the sunken ventilation duct in the plane where the fan 4 and the filter assembly are connected, and is fixedly installed on the clamping plate on the inner wall of the main body 1, dividing the sunken ventilation duct into two parts, the upper and lower parts. The cleaning of the breathable smoke hood 9 is relatively simple. Open the inspection door 18, remove it, clean it, and then clamp it again.

[0034] In order to ensure that all smoke can enter the filter assembly, the lower part of the downdraft ventilation duct is an independent channel connected to the air inlet 2, and its maximum diameter is smaller than the corresponding caliber of the upper part of the downdraft ventilation duct.

[0035] See also Figure 3 As shown, the smoke is purified in the form of hierarchical filtration. Specifically, the filter assembly includes a multi-stage filter layer and an activated carbon filter layer 10. The multi-stage filter layer is close to the diffusion chamber, and the activated carbon filter layer 10 is close to the fan 4. First, the particulate matter in the smoke is filtered out, and then the adsorption performance of the activated carbon is used to physically and chemically adsorb the VOC (volatile organic compounds) in the smoke to achieve the purpose of purification.

[0036] The multi-stage filter layer includes a pre-filter cotton layer 11 , a primary filter 12 , a medium filter 13 and a high efficiency filter 14 from one side of the diffusion chamber to one side of the activated carbon filter layer 10 .

[0037] Pre-filter cotton: Filters particles and suspended solids larger than 5.0μm. In view of the characteristics of the industry, during the electronic welding process, a large amount of condensable fumes containing rosin are generated. The pre-filter cotton can filter and absorb most of these substances, extending the service life of the medium efficiency filter 13, high efficiency filter 14 and activated carbon filter;

[0038] Primary filter 12: Filters 1.0-5.0μm particles and suspended solids. The primary filter 12 uses aluminum alloy material as the frame and galvanized iron wire as the skeleton. The main body 1 filter material uses high-quality chemical fiber non-woven fabric, which has the characteristics of small resistance, large air volume and large dust holding capacity.

[0039] Medium efficiency filter 13: Filter 1-0.5μm particles and suspended solids. The plate-type medium efficiency filter 13 is used. The main body 1 filter material is synthetic fiber or composite fiber filter material, equipped with an internal metal bracket, the outer frame is made of aluminum alloy frame, and the filter screen is made into a V shape to increase the filtering area. It has the advantages of firm structure, low resistance, large air volume, and long service life.

[0040] High efficiency filter 14: Filters particles and suspended solids below 0.3μm. A high efficiency filter 14 without a partition is used, and the filter material of the main body 1 is ultra-fine glass fiber filter paper, and hot melt glue is used as a separator of the filter element. It has the advantages of small size, light weight, easy installation, stable efficiency, and uniform wind speed.

[0041] Activated carbon filter: used to adsorb VOC (volatile organic compounds) in the filtered air. Depending on the different components of VOC, physical adsorption, chemical adsorption, or physical / chemical adsorption is used.

[0042] In a disclosed embodiment, an exhaust noise reduction grille 15 is provided in the exhaust chamber 5, an exhaust cover plate 16 is provided on the top of the main body 1 corresponding to the exhaust noise reduction grille 15, and the exhaust port 6 is arranged on the exhaust cover plate 16. The exhaust noise reduction grille 15 can buffer the airflow during the discharge of the treated flue gas, reduce the sound of the airflow flowing rapidly through the reflux chamber, and achieve the purpose of noise reduction.

[0043] In a disclosed embodiment, a control panel 17 is further provided on the outer surface of the main body 1, a maintenance port 19 is provided on the top of the main body 1, and the maintenance port 19 can completely remove the filter assembly, a power socket 20 is provided on the side, and a universal wheel 21 is provided on the bottom.

[0044] The overall structure of the equipment adopts the method of placing the fan 4 downward, and the air inlet direction of the fan 4 is the filter assembly. The bottom air inlet is connected to the connecting pipe 8, and the filtered smoke is directly transported into the filter assembly through the sunken air inlet channel 7 set around the filter chamber. The filtered smoke passes through the negative pressure generated by the fan 4, and passes through the pre-filter cotton, the primary filter 12, the medium efficiency filter 13, the high efficiency filter 14 and the activated carbon filter in sequence. The clean air after purification and filtration is discharged from the exhaust port of the fan 4 into the exhaust chamber 5 of the equipment, and passes through the noise reduction grille set in the exhaust chamber 5 to consume the kinetic energy of the airflow, reduce the noise, and then discharged from the equipment.
