Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature exhaust gas treatment, and in particular to a high-efficiency purification system for high-temperature exhaust gas from a tunnel furnace and a purification method thereof. Background Art

[0002] Tunnel furnace is a kind of heating equipment widely used in industrial production. It is a tunnel-type mechanical equipment that completes the baking and heating of objects through heat conduction, convection and radiation. The raw materials processed in the high-temperature tunnel furnace (such as ceramic raw materials, metal raw materials, etc.) will decompose and volatilize at high temperatures. Some components in these raw materials (such as carbonates, organic matter, etc.) will decompose and produce gas and particulate matter at high temperatures. For example, the decomposition of carbonates will produce carbon dioxide gas and carbonate particles, and the volatilization of organic matter will produce organic particulate matter. These particulate matter may contain substances that are harmful to the human body and the environment, and purification devices are required to filter them out.

[0003] Most of the existing exhaust gas purification devices rely on filters to capture and filter particles in the exhaust gas. However, as particles continue to accumulate on the filter, the filter will gradually become clogged, which will affect its filtering efficiency. Although some exhaust gas purification devices are equipped with a cleaning brush to clean the surface of the filter, this cleaning method is relatively simple, the cleaning effect is often unsatisfactory, and some particles will be embedded in the mesh of the filter, which is not easy to clean, reducing the overall effect of exhaust gas purification.

[0004] Therefore, a tunnel furnace high-temperature exhaust gas high-efficiency purification system and a purification method thereof are needed to solve the above problems. Summary of the invention

However, as the particulate matter continues to accumulate on the filter, the filter will gradually become clogged, thereby affecting its filtration efficiency. Although some exhaust gas purification devices are equipped with a cleaning brush to clean the surface of the filter, this cleaning method is relatively simple, and the cleaning effect is often unsatisfactory.

[0022] S1, high-temperature exhaust gas enters the filter chamber through the exhaust gas inlet pipe, and enters the post-treatment chamber after being filtered by the filter component for particulate matter in the exhaust gas. At the same time, the servo motor is started;

[0023] S2, the output end of the servo motor drives the rotating rod to rotate, which drives the driving gear to rotate through the rotating rod, drives the fixed rod to rotate through the setting of the driving gear and the driven gear, and drives the cleaning brush to rotate through the fixed rod to clean the surface of the filter assembly;

[0028] S7, the exhaust gas blown out by the high-speed fan enters the exhaust chamber after passing through the metal filter and blows onto the semicircular baffle. The water droplets flow down through the guide groove and merge into the cleaning liquid. The exhaust gas is discharged through the exhaust pipe.

[0029] Beneficial effects of the present invention:

[0030] 1. The servo motor and the rotating rod drive the driving gear to rotate, and the driving gear, the driven gear and the fixed rod drive the cleaning brush to rotate and clean the surface of the filter assembly;

[0031] 2. When the cleaning brush rotates, the special-shaped gear is driven to rotate through the fixed block, and the ring gear is driven to rotate intermittently through the setting of the special-shaped gear, the rotating gear, the pipe sleeve and the sleeve, and the rotating shaft is driven to rotate intermittently through the setting of the ring gear, the intermediate gear and the No. 1 gear, and the filter assembly is driven to rotate intermittently through the rotating shaft, and the rotation speed of the filter assembly is different from the rotation speed of the cleaning brush, thereby improving the cleaning effect;

[0032] 3.

[0033] 4. The rotating gear drives the fixed cylinder to rotate while rotating, and the fixed cylinder drives the knocking balls to move one by one in the arc groove. The setting of the arc groove not only makes the filter assembly stop rotating when the special-shaped gear is separated from the rotating gear, but also plays a role in limiting the filter assembly, and makes it easier to clean the surface of the metal filter with a cleaning brush; and the knocking ball repeatedly knocks the metal filter, so that the metal filter vibrates, which is conducive to blowing out the water droplets and particles in the mesh of the metal filter;

[0034] 5. While the cleaning brush is rotating, it is cleaned by the cleaning liquid, and at the same time, part of the cleaning liquid is carried to clean the surface of the metal filter. A small amount of cleaning liquid remains in the mesh of the metal filter and mixes with the particles. The cleaning liquid reduces the friction between the particles and the mesh of the metal filter, plays a "lubricating" role, and is conducive to the discharge of particles from the mesh of the metal filter;

[0035] 6. By setting up a circulating liquid inlet pipe and a circulating liquid discharge pipe to circulate and replace the cleaning liquid, it is not only convenient to discharge the particles mixed with the cleaning liquid and improve the cleaning effect, but also the filter component can be cooled, reducing the damage to the filter component caused by high temperature and increasing the service life of the filter component.
