Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of sludge combustion furnaces, and in particular, to a sludge combustion furnace with a flue gas purification function. Background Art

[0002] A sludge combustion furnace is a special equipment that uses high-temperature combustion to reduce, render harmless, and recycle sludge. It is widely used in sludge devices produced by municipal sewage treatment plants and industrial wastewater treatment. After the sludge is burned, the organic and inorganic substances contained in the sludge are decomposed, burned, and transformed in a high-temperature oxidation reaction. The incompletely burned substances and reaction products are released in the form of gas. The composition of these gases is complex, so the flue gas generated needs to be purified before it can be discharged into the atmosphere.

[0003] After the flue gas is discharged, it is usually passed through a purification device, where the flue gas will contact the activated carbon and filter plates. The activated carbon and filter plates will adsorb and filter the particles in the flue gas, thereby purifying the flue gas. However, after a period of use, the activated carbon usually needs to be replaced or the filter plates need to be cleaned. When collecting the activated carbon that has been adsorbed, some purification devices are located at a high place, so a discharge port is usually opened at the bottom of the purification box to allow the activated carbon to fall under the action of gravity. However, dust is easily generated after the activated carbon falls, and the dust floating in the factory building can easily cause damage and impact on the workers. Summary of the Invention
