Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a roller kiln waste gas treatment device. Background Art

[0002] The roller kiln is a tunnel kiln with a narrow cross-section. Unlike a kiln car tunnel kiln, it does not use a kiln car loaded with products to operate, but is composed of rollers arranged in parallel and crossing the cross-section of the kiln working channel. The products are placed on the rollers and transported into the kiln as the rollers rotate. The firing process is completed in the kiln, so it is called a roller kiln. When the roller kiln is in operation, waste gas will be generated, especially when lanthanum oxide cerium polishing powder is processed. Lanthanum oxide cerium polishing powder will generate a large amount of waste gas that pollutes the air, so the waste gas needs to be treated.

[0003] Referring to the existing Chinese patent with announcement number CN211291011U, a roller kiln exhaust duct and device are disclosed. By arranging a lining ceramic on the inner side of the stainless steel pipe, the direct contact between the stainless steel pipe and the alkaline gas is hindered to prevent it from being corroded. At the same time, the height of the bell mouth can be adjusted by loosening the clamp to ensure the best exhaust state, and the bell mouth can also be disassembled to clean the internal alkaline crystal blockage, which can effectively reduce the residual alkali of the product, improve the product quality, and extend the service life of the exhaust duct. In addition, the device is also provided with a liquid storage tank to treat the alkaline gas in the exhaust gas, avoiding its direct discharge and harm to the environment. When the above-mentioned device is in use, although there is a liquid storage tank to treat the exhaust gas, there are problems such as the inability to transport the gas and the subsequent multi-mode treatment of the exhaust gas.
