Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to a device for reusing incompletely combusted particles in flue gas. Background Technology

[0002] Flue gas is a mixture of gases and soot, and is a major cause of atmospheric pollution in residential areas. The composition of flue gas is very complex. The gases include water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides, while the soot includes fuel ash, coal particles, oil droplets, and high-temperature pyrolysis products. Flue gas contains some incompletely burned particles, so it is necessary to recycle and reuse these incompletely burned particles.

[0003] Publication No. CN218046959U discloses a flue gas particulate filtration and recovery device. By connecting an inlet pipe to a flue gas recovery pipeline, flue gas enters the inlet pipe and then the interior of a buffer frame. The buffer plate provides some buffering for the flue gas. After dust accumulates on the surface of the buffer plate and its perforations, an electric telescopic rod is activated via the control panel. This electric telescopic rod drives a scraper block to move downwards on the surface of the buffer plate, scraping away the dust from the perforations and causing it to fall into the discharge box. Simultaneously, when the scraper block rises, an electric push rod is activated via the control panel, pushing a moving plate. This prevents the scraper block from contacting the surface of the buffer plate and thus prevents particulate impurities from being scraped upwards, solving the problem of previous devices being unable to scrape dust from the surface of the buffer plate. However, this patent still has the following problems in practical use:

[0004] Although this flue gas particulate filter and recovery device can scrape off dust from the surface of the buffer plate, the scraping block, driven by an electric telescopic rod, moves downwards on the surface of the buffer plate. However, because the dust particles are of varying sizes, the scraping block can only move on one side of the buffer plate. This causes flue gas particles to enter the other side of the buffer plate through the through-holes while the scraping block is removing dust, thus failing to completely clean both dust and flue gas particles. This affects the cleaning effect of the buffer plate. Furthermore, since the device cannot purify the flue gas containing harmful substances, it contributes to air pollution.

[0005] Therefore, a device for reusing incompletely combusted particles in flue gas is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a device for reusing incompletely combusted particles in flue gas, in order to solve the problems mentioned in the background art. Because the size of dust particles is not fixed, the scraper can only move on one side of the buffer plate. As a result, when the scraper removes dust, flue gas particles can enter the other side of the buffer plate through the through holes on the surface of the buffer plate, thus failing to clean the dust and flue gas particles, affecting the cleaning effect of the buffer plate. At the same time, the flue gas contains certain harmful substances, and the device cannot purify the flue gas, thus causing certain air pollution.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for reusing incompletely combusted particles in flue gas, comprising a particle recovery mechanism and a fixed support installed inside the particle recovery mechanism;

[0008] A flue gas purification mechanism is provided on one side of the particle recovery mechanism, and a purification box is provided on the top of the flue gas purification mechanism.

[0009] Also includes:

[0010] The particle recovery mechanism includes a fixed base, on the top of which mounting brackets are symmetrically installed, and an air inlet pipe is fixedly installed on the outer side of one side of the mounting brackets.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This device for reusing incompletely combusted particles in flue gas starts a cleaning motor to drive a rotating worm gear. Utilizing the meshing connection between the rotating worm gear and the rotating worm wheel, the rotating worm wheel drives the cleaning connecting rod and the cleaning spiral scraper to rotate. Since the cleaning spiral scraper is located on both sides of the filter screen, both sides of the filter screen can be cleaned during cleaning, thereby improving the cleaning effect. Stirring allows for thorough mixing of flue gas and purification liquid, thus improving the flue gas purification effect.

At the same time, the sealed maintenance cover can be opened through the maintenance handle to facilitate cleaning of the inside of the filter recovery box and replacement of the filter screen. Starting the cleaning motor drives the rotating worm gear to rotate. Utilizing the meshing connection between the rotating worm gear and the rotating worm wheel, the rotating worm wheel drives the cleaning connecting rod and the cleaning spiral scraper to rotate. Since the cleaning spiral scraper is set on both sides of the filter screen, both sides of the filter screen can be cleaned during cleaning, thereby improving the cleaning effect of the filter screen.

[0021] 2. By setting up a flue gas purification mechanism, not only can purification liquid be placed inside the mixing chamber, with the height of the purification liquid exceeding the middle of the diversion pipe, but the purification liquid can also be used to purify harmful substances in the flue gas, preventing the flue gas from polluting the air. At the same time, the stirring motor is started to drive the stirring plate and stirring rod to rotate, and the flue gas and purification liquid can be fully mixed through stirring, thereby improving the flue gas purification effect. The drying chamber can be used to dry the flue gas, and the purification carbon plate inside the purification chamber can be used for secondary purification of the flue gas, further improving the flue gas purification effect.
