Energy-saving and environment-friendly furnace kiln flue gas treatment device and treatment method thereof

Abstract

The invention relates to the technical field of furnace kiln flue gas treatment, in particular to an energy-saving and environment-friendly furnace kiln flue gas treatment device and a treatment method thereof. The device comprises a shell, an air inlet is formed in the side, close to the bottom, of the side wall of the shell, cleaning windows are arranged around the outer wall of the shell, an exhaust port is formed in the center of the upper surface of the shell, and a supporting ring is fixedly connected to the position, close to the top of the air inlet, of the side wall of an inner cavityof the shell; and a first filter screen is fixedly connected to the position, close to the top exhaust port, of the side wall of the inner cavity of the shell, a water storage tank is arranged at thebottom of the inner cavity of the shell, and a second filter screen is fixedly connected to the position, close to the top of the water storage tank, of the side wall of the inner cavity of the shell. Through an arranged fixed seat, a cyclone device is fixed, and particulate matter in flue gas is thrown to the inner wall of the fixed seat due to centrifugal force and can be prevented from adhering to the inner wall of a purification tower, and the problems of corrosion and difficulty in cleaning of the inner wall of the purification tower due to long-term adhesion of the particulate matter are solved.

Description

Technical field [0001] The present invention relates to the field of furnace kiln fluttering techniques, and in particular, it is related to a fuel-saving environmental protection type furnace kiln flue gas treatment device. Background technique [0002] During the production of industrial kiln, it is required to produce a refractory material. Therefore, in order to improve the temperature of the kiln cavity, a large amount of combustion fuel is required, such as coal block, etc., there will be a large amount of exhaust gas, and when the high temperature kiln producing refractory, it is also necessary to release exhaust gas in the chamber, general gas The cooling and dust removal treatment is performed by the purification tower. Finally, the existing purification tower is typically generated by the guide action of the cyclone, and the fluctuating force is generated during the rotation of the cyclone, the particulate matter is very medium. It is easy to detach it from the flue gas...

AI Technical Summary

Problems solved by technology

Therefore, in order to increase the temperature of the inner chamber of the kiln, it is necessary to burn a large amount of fuel, such as coal, which will release a large amount of waste gas. The cooling and dust removal process is carried out through the purification tower, and finally discharged from the exhaust channel. In the process of cooling and dust removal in the existing purification tower, generally through the guiding effect of the swirl plate, a strong centrifugal force is generated during the rotation of the swirl plate, and the particles are very large. It is easy to get out of the flue gas and be thrown to the tower wall, and flow to the bottom of the tower under the action of gravity to realize the separation of particles. However, after the particles are thrown to the tower wall, they often adhere to the inner wall of the purification tower, and it is difficult to clean the inner wall of the purification tower. And if it is not cleaned for a long time, it will easily cause the problem of corrosion of the inner wall of the purification tower. Therefore, the purpose of the present invention is to use an energy-saving and environment-friendly furnace flue gas treatment device to solve the problem of passing the particles adhered to the inner wall of the purification tower by the swirl plate during the process of filtering particles, so as to prevent purification. The problem of corrosion on the inner wall of the tower
