Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a waste gas purification, cooling and dust removal cylinder. Background Art

[0002] The waste gas and various dusts discharged from traditional steel mills seriously pollute the environment. The main sources of waste gas in steel mills include the transportation, loading and unloading and processing of raw materials and fuels, which generate a large amount of dust-containing waste gas; the various kilns in steel mills will generate a large amount of dust-containing and harmful gas waste gas during the reproduction process; and the waste gas discharged by chemical reactions in the production process, such as smelting, coking, chemical products and steel pickling.

[0003] Most of the existing waste gas treatment equipment adsorbs and purifies harmful gases in the waste gas, but ignores the fact that impurities in the waste gas will enter the adsorption structure together with the harmful gases. After long-term operation, the accumulation of impurities will block the adsorption structure, thereby greatly reducing the service life of the adsorption structure and reducing the waste gas treatment efficiency. In addition, the waste gas flow rate is too large, resulting in poor treatment effect. Summary of the invention

[0004] The object of the present invention is to provide an exhaust gas purification, cooling and dust removal cylinder to overcome the above-mentioned defects in the prior art.

Rod, a cleaning cylinder is connected to the outer circumference of each rotating rod, the upper and lower ends of the cleaning cylinder are in contact with the lower heat exchange plate and the upper heat exchange plate, a partition plate is fixedly provided in the connecting box, an air outlet chamber and a dust collecting chamber are opened in the connecting box, an air outlet pipe is fixedly connected to the rear side wall of the air outlet chamber, a connecting pipe evenly distributed circumferentially is fixedly connected to the upper side of the air outlet chamber, the air outlet chamber and the dust collecting chamber are separated by the partition plate, a collecting partition is fixedly provided at the upper end of the connecting box, a through hole evenly distributed circumferentially is opened at the upper end of the connecting box, the through hole is located on the inner side of the collecting partition, and the through hole is connected to the dust collecting chamber.

[0006] Preferably, each of the lower heat exchange plate and the upper heat exchange plate are connected to a cooling pipe that passes through the upper and lower parts, and water ring boxes are fixedly provided at the upper and lower ends of the purification cylinder, and the right ends of the two water ring boxes are respectively connected and fixed with a water inlet pipe and a water outlet pipe, and water ring cavities are opened in the two water ring boxes, and the water inlet pipe and the water outlet pipe are connected with the cooling pipe and the water ring cavities on the upper and lower sides, and a power motor is fixedly provided at the lower end of the connecting box, and the upper end of the power motor is connected to a driving wheel, and a driven gear ring is fixedly provided at the lower end of the rotating cylinder, and the driven gear ring is meshed with the driving wheel, and fixed platforms evenly distributed up and down are fixedly provided on the outer periphery of the air inlet pipe, and a bevel gear platform is fixedly provided in each of the fixed platforms, and a bevel gear platform is fixedly provided at the end of the rotating rod inserted into the rotating cylinder, and the bevel gear is meshed with the bevel gear platform.

[0007] The beneficial effects of the present invention are:

[0008] The increased space in the purification chamber and the circumferentially evenly distributed connecting pipes increase the residence time of the exhaust gas in the purification chamber, further slowing down the flow speed of the exhaust gas at the lower end of the purification tube, thereby preventing the exhaust gas flow from interfering with the dust collection work at the lower end. The lower heat exchanger fins and the upper heat exchanger fins absorb heat and exchange heat with the outside world, thereby effectively reducing the temperature and dust content in the exhaust gas.

[0009] Through the meshing between the bevel gear table and the bevel gear, the rotating rod rotates during the revolution, thereby extending the service life of the cleaning cylinder at the rotating rod and increasing the cleaning effect of the cleaning cylinder on the lower heat exchange plate and the upper heat exchange plate.

[0010] By absorbing the heat in the exhaust gas, the flow speed of the exhaust gas is slowed down, and the residence time of the exhaust gas in the purification chamber is further increased, so that the purification work of the exhaust gas can be fully completed. BRIEF DESCRIPTION OF THE DRAWINGS
