Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and in particular relates to an oil fume treatment filter based on a condensation method. Background Art

[0002] Industrial fume is an inevitable by-product of the industrial production process. It is mainly produced by heating, combustion and other process links. It comes from many industries such as food processing, machinery manufacturing and welding. Its composition mainly includes the heating and combustion of oil, fuel or other substances.

[0003] During the mechanical processing process, such as heat treatment or quenching of parts, the heating of materials such as engine oil and lubricating oil will also produce oil smoke. These oil smoke not only pose a threat to the health of workers, but may also cause safety accidents, such as personal injury caused by slippery floors and fire hazards caused by increased oil smoke reserves. In addition, oil smoke can also damage mechanical equipment, reduce equipment efficiency, increase energy consumption, and shorten service life.

[0004] For the above-mentioned oil smoke, the traditional method is usually to directly use a filter to physically filter the oil smoke to reduce the discharge of dust, grease and other substances into the external environment and avoid the impact on the environment. However, the effect of direct filtration is poor. Some harmful oil substances have gaseous oil molecules, which makes these gaseous oil molecules pass through the filter and then diffuse into the air, causing impact on the environment. This needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0047] Embodiment 1:

[0048] This embodiment provides a fume treatment filter based on condensation, including:

[0049] The box body 1 has an inlet 2 and an outlet 3 respectively formed on the inner walls on both sides, and a first filter screen 4 is provided at the outlet 3, and a filter cavity 5 is formed inside;

[0050] A cooling assembly 6 is installed in the box 1 and is used to cool industrial oil smoke;

[0051] The filter assembly 7 is installed in the housing 1 and divides the filter chamber 5 into an upper chamber 50 and a lower chamber 51;

[0052] The cooling assembly 6 is located in the upper chamber 50, the filtering assembly 7 is located in the lower chamber 51, and the inlet 2 and the outlet 3 are respectively opened at both ends of the upper chamber 50;

[0053] At the same time, a drain port is also provided on the bottom of the box body, and the drain port is connected to a drain pipe for collecting liquid grease impurities, and the first filter screen 4 is a conventional setting of existing filters, and its specific structure and material are not repeated here.

[0054] It can be seen from this embodiment that by using the cooling component 6 to cool down the industrial oil smoke with a high temperature, the gaseous grease molecules carried by it are condensed into liquid grease, and then filtered by the filtering component 7, the gaseous grease molecules can be effectively intercepted to prevent them from diffusing into the air, thereby improving the filtering effect;

[0055] A filter assembly 7 is provided in the filter chamber 5 for dividing the filter chamber 5 into an upper chamber 50 and a lower chamber 51, so as to further filter the liquid grease formed after the condensation of the industrial oil fume, process the industrial oil fume and form gaseous emissions and solid-liquid separated impurities, so as to facilitate the subsequent separate treatment of solid and liquid filtrates, improve the treatment efficiency and reduce the treatment cost.

[0056] Embodiment 2:

[0057] This embodiment provides an oil fume treatment filter based on condensation mode, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The cooling component 6 includes:

[0058] A cooling pipe 60 is installed in the upper chamber 50 and is used to cool the industrial oil fume;

[0059] The flow guiding structure 61 is installed in the upper chamber 50 and includes a first partition plate 610 disposed near the inner wall of the rear side of the box body 1 and a second partition plate 611 disposed near the inner wall of the front side of the box body 1;

[0060] The first baffles 610 and the second baffles 611 are arranged alternately, and the cooling pipes 60 are installed in the first baffles 610 and the second baffles 611 respectively;

[0061] Meanwhile, the first partition plate 610 and the second partition plate 611 may be made of a material with good heat conduction efficiency, such as aluminum alloy.

[0062] It can be seen from this embodiment that by configuring the cooling assembly 6 to be a cooling pipe 60 and a flow guide structure 61 including first baffles 610 and second baffles 611 arranged alternately, the moving distance of the industrial oil smoke in the filter cavity 5 is increased, thereby improving the heat conduction efficiency with the cooling pipe 60;

[0063] Furthermore, the tortuous passage allows the industrial oil smoke to collide with the first partition plate 610 and the second partition plate 611, and the liquid oil molecules come into contact with the solid impurities, so that the liquid oil molecules fall due to condensation, carrying the solid impurities with them.

[0064] Embodiment 3:

[0065] This embodiment provides an oil fume treatment filter based on condensation mode, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The cooling pipe 60 includes:

[0066] The U-shaped tube 600U is embedded in the first partition plate 610 and the second partition plate 611, and one end of the U-shaped opening extends out of the top surface of the box body 1;

[0067] The connecting pipe 601 is installed on the top surface of the box body 1 and is used to connect two adjacent U-shaped pipes 600U;

[0068] The liquid inlet pipe 602 is installed on the top surface of the box body 1 and is used to input cooling medium into the U-shaped pipe 600U;

[0069] The liquid outlet pipe 603 is installed on the top surface of the box body 1 and is used to output the cooling medium to the U-shaped pipe 600U;

[0070] Among them, one end of the U-shaped opening of the U-shaped tube 600U is provided with an external thread, and the U-shaped tube 600U passes through the top wall of the box body 1 and the first partition plate 610 or the second partition plate 611, and extends to the outside of the top wall of the box body 1, and is fixed by bolts, and the connecting tube 601, the liquid inlet pipe 602 and the liquid outlet pipe 603 are all fixed with bolts.

[0071] It can be seen from this embodiment that by setting the cooling pipe 60 into the above-mentioned structure, on the one hand, the heat transfer area is increased and the heat conduction efficiency is ensured. On the other hand, by recycling the cooling medium and applying the obtained heat to other equipment or functions, energy saving effect is achieved and energy loss is reduced.

[0072] Embodiment 4:

[0073] This embodiment provides an oil fume treatment filter based on condensation, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0074] A return air outlet is provided on the inner wall of the lower chamber 51, and a return air inlet is provided on the inner wall of the upper chamber 50;

[0075] Among them, a return air duct 8 is provided between the return air outlet and the return air inlet;

[0076] At the same time, the return air duct 8 is fixed to the box body 1 by bolts and a sealing ring is provided.

[0077] It can be seen from the present embodiment that by opening a return air outlet on the inner wall of the lower chamber 51 and a return air inlet on the inner wall of the upper chamber 50, part of the gaseous matter passing through the filter assembly 7 returns to the upper chamber 50, thereby improving the treatment effect of industrial oil fume and effectively ensuring that the discharged industrial oil fume meets the emission standards.

[0078] Embodiment 5:

[0079] This embodiment provides an oil fume treatment filter based on condensation mode, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including:

[0080] Fan 9, installed at the return air inlet;

[0081] The fan 9 is used to blow the gas in the return air duct 8 into the upper chamber 50 ; and the specific structure of the fan 9 is prior art and will not be described in detail here.

[0082] It can be seen from this embodiment that by setting the fan 9, gas flow is generated in the return air duct 8, thereby causing the gas entering the lower chamber 51 through the filter assembly 7 to reflux, thereby ensuring the treatment effect of industrial oil fume and preventing substandard industrial oil fume from being discharged through the lower chamber 51.

[0083] Embodiment 6:

[0084] This embodiment provides a fume treatment filter based on condensation, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The filter assembly 7 includes:

[0085] The second filter screen 70 is installed in the housing 1 and is located at the connection between the upper chamber 50 and the lower chamber 51;

[0086] A slideway 71 is mounted on the inner wall of the box body 1;

[0087] Slide blocks 72 are mounted at both ends of the second filter screen 70 and are slidably connected to the slideway 71;

[0088] The box body 1 includes a main body 10 and a door 11, and a sealing member is provided between the main body 10 and the door 11;

[0089] Meanwhile, the slideway 71 may have a U-shaped cross-section, and in addition to the slider 72 , a roller may be provided to move relative to the slideway 71 .

[0090] It can be seen from this embodiment that by using the second filter 70 to separate the liquid grease and solid impurities, it is convenient to separately process the solid and liquid filtrates in the subsequent process, thereby improving the processing efficiency and reducing the processing cost;

[0091] The arrangement of the slideway 71 and the slider 72 as well as the main body 10 and the door 11 facilitates the disassembly of the second filter screen 70, and further facilitates the cleaning and replacement thereof.

[0092] Embodiment 7:

[0093] This embodiment provides an oil fume treatment filter based on condensation, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0094] The second filter screen 70 is in an accordion leaf structure and is made of metal.

[0095] It can be seen from this embodiment that by setting the second filter 70 into an accordion leaf structure, on the one hand, the effective filtering area is increased and the filtering effect is improved. On the other hand, the accordion leaf structure allows solid impurities to accumulate at the bottom, thereby extending the service life of the second filter 70 and ensuring the filtering effect.

[0096] The second filter screen 70 made of metal can improve its structural strength.

[0097] Embodiment 8:

[0098] This embodiment provides an oil fume treatment filter based on condensation mode, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including:

[0099] An air intake duct 12 is installed on the side of the box body 1 at the inlet 2;

[0100] An air outlet pipe 13 is installed on the side of the box body 1 at the outlet 3;

[0101] The air inlet end of the air inlet pipe 12 is smaller than the air outlet end, and the air inlet end of the air outlet pipe 13 is larger than the air outlet end.

[0102] It can be seen from the present embodiment that the air inlet pipe 12 having an air inlet end smaller than the air outlet end can decelerate the industrial oil fume before entering the box body 1, thereby preventing the industrial oil fume from moving too fast and affecting the condensation effect. Similarly, the air inlet end of the air outlet pipe 13 is larger than the air outlet end, thereby accelerating the discharge of the treated industrial oil fume and improving the emission efficiency.

[0103] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
