Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum air quenching furnaces, in particular to a vacuum air quenching furnace fume purifier with high safety. Background Art
[0002] Vacuum gas quenching furnace flue gas purifiers are specially designed to treat the flue gas and harmful substances generated during the operation of vacuum gas quenching furnaces. These purifiers are widely used in fields such as metallurgy, machinery, and aerospace. Especially during heat treatment of materials, they effectively remove particulate matter, harmful gases, and other pollutants from the flue gas, ensuring a safe working environment and compliance with environmental standards.
[0003] The Chinese invention patent with application number CN219186234U discloses an anti-clogging vacuum air quenching furnace flue gas purifier, which includes a purification cylinder, a filter plate is slidably connected to the middle position of the air transmission channel, a fixed plate is provided on the top of the filter plate, and a rack is provided on the upper plate surface of the fixed plate. At the same time, limit plates are provided on both sides of the rack, and a half gear meshing with the rack is provided above the filter plate in the interior of the purification cylinder, and springs are provided on the limit plates on both sides. The movable ends of the springs are pressed outward against the corresponding inner wall surfaces. The utility model solves the problem that the flue gas generated by the vacuum high-pressure gas quenching furnace during quenching is not cleaned and becomes clogged when the purifier is used to purify the flue gas. The flue gas purifier proposes that the originally fixed filter plate is designed as a spring-retractable structure, and the rebound characteristics of the spring are used to make the filter plate fully vibrate, thereby throwing out impurities on its surface to avoid clogging of the filter screen.
[0004] In the prior art, flue gas generated by vacuum quenching furnaces is typically filtered directly out of the flue gas pipeline using an integrated filter. However, this integrated cleaning assembly only removes large particles of smoke from the flue gas, but cannot individually remove the various harmful components within the flue gas. Therefore, the flue gas cleaning assembly in the prior art cannot achieve effective cleaning results. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a vacuum air quenching furnace flue gas purifier with high safety.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A highly safe vacuum air quenching furnace flue gas purifier comprises a vacuum air quenching furnace and further comprises:
[0008] The smoke and dust filtering assembly includes an input pipe docked at one side of the vacuum gas quenching furnace, a filter box is docked and installed on one side of the input pipe, a slide is provided inside the filter box, a filter element is slidably installed inside the slide, a cover plate is docked at one side of the filter element, and a handle is provided on the surface of the cover plate.
[0009] Further technical solutions also include:
[0010] The air washing component includes an intermediate tube docked and installed on one side of the filter box, an air washing tank is docked and installed on one side of the intermediate tube, a rotating shaft is rotatably installed inside the air washing tank, a motor is docked and installed on one side of the rotating shaft, and a stirring blade is rotatably set on the surface of the rotating shaft.
[0011] According to a further technical solution, the intermediate pipe is butt-jointed and installed at the bottom of the scrubber tank, and scrubbing liquid is provided inside the scrubber tank.
[0012] Further technical solutions also include:
[0013] The terminal cleaning component includes an output pipe docked and installed on one side of the gas washing tank, one side of the output pipe is docked and installed with a tank body, the inside of the tank body is plugged and installed with a filter material, and one side of the filter material is provided with an air outlet.
[0014] According to a further technical solution, the filter material is installed in a sliding manner inside the tank body, and a hole is provided on one side of the air outlet.
[0015] According to a further technical solution, the smoke filter assembly, the air washing assembly and the terminal cleaning assembly are arranged in a passage, and the installation order thereof can be changed.
[0016] According to a further technical solution, a cover is provided on the top of the vacuum gas quenching furnace, and the cover is made of high temperature resistant material.
[0017] Compared with the prior art, the present invention provides a vacuum air quenching furnace flue gas purifier with high safety, which has the following beneficial effects:
[0018] The smoke filter assembly removes dust from the flue gas, primarily removing large particles of pollutants. When dust from the gas quenching furnace enters the filter cartridge through the inlet pipe, it is absorbed and cleaned by the plugged-in filter element. This prevents large particles from being carried over to subsequent processes.
[0019] The scrubbing assembly adds scrubbing solution to the interior of the scrubber, absorbing harmful substances from the flue gas through a chemical reaction. Because harmful substances in the flue gas come into contact with the scrubbing solution over a large area within the scrubber, and the stirring structure allows for effective scrubbing, the system is designed to ensure efficient scrubbing.
[0020] The terminal cleaning component is set up to achieve the effect of terminal exhaust cleaning. The pre-treated exhaust gas enters the interior of the tank through the output pipe, achieving a cleaning effect on the surface of the filter material, thereby achieving the effect of harmless gas discharge.

[0037] Working principle:
[0038] During the actual design process, the present invention aims to avoid the following defects in the prior art: "In the prior art, the flue gas generated by the vacuum quenching furnace is generally directly removed from the inside of the pipe by an integrated filtration method. However, the integrated cleaning component only removes large particles of smoke in the smoke, and the different harmful components in the smoke cannot be cleaned separately. Therefore, the smoke cleaning component in the prior art cannot achieve an effective cleaning effect." Therefore, the present invention specifically proposes a smoke filter component 2, an air washing component 3 and a terminal cleaning component 4;
[0039] The device configures the traditional integrated cleaning tank into a multi-channel modular cleaning unit, so that the cleaning materials of different parts are different, thereby making the cleaning effect of different parts on different materials more thorough.
[0040] Soot filter assembly 2:
[0041] The core components of this assembly are the filter cartridge 6 and filter element 7. The filter element 7 is inserted and mounted within the chute 19 of the filter cartridge 6 via the cover plate 8. This allows the filter element 7 to be removed from the filter cartridge 6 at any time for self-cleaning and replacement. This structure ensures that the filter element 7 is cleaned immediately and prevents it from becoming unusable after prolonged use. A handle 20 on the cover plate 8 controls the insertion and removal of the filter element 7.
[0042] Gas washing component 3;
[0043] The main function of this component is to directly contact the flue gas with the scrubbing liquid through a chemical reaction with harmful gases in the flue gas. At the same time, in order to increase the contact effect between the flue gas and the scrubbing liquid, a rotating shaft 11 and a motor 16 are installed inside the scrubbing tank 10. The motor 16 controls the stirring blades 12 to stir the inside of the scrubbing tank 10 through the rotating shaft 11, thereby increasing the contact area between the flue gas and the scrubbing liquid and making the reaction more effective. The toxic substances in the flue gas are either directly dissolved or retained inside the scrubbing tank 10 through chemical reactions.
[0044] End cleaning component 4:
[0045] This component is the final step in cleaning the flue gas, primarily aiming to achieve harmless emissions and prevent backdraft. The treated flue gas is then fed into the interior of the tank 14 through the output pipe 13, where it is finally cleaned by the filter material 15, ensuring that the discharged flue gas meets environmental standards. Furthermore, the air outlet 18 containing the filter material 15 prevents backdraft of pollutants from the air.
