Description

Technical Field

[0001] The present invention relates to the technical field of cement kiln equipment, and in particular to a cement kiln comprehensive energy-saving and emission-reduction integrated system. Background Art

[0002] A cement kiln is a facility used to produce cement. Its main function is to convert raw materials into cement clinker through high-temperature calcination. However, during the operation of a cement kiln, mercury, as a trace element, enters the cement production process along with raw materials and fuel. When the flue gas is discharged, the mercury content in the gas will exceed the standard. Tail gas treatment is an effective measure to reduce mercury pollution emissions during the co-treatment of hazardous waste in cement kilns. Activated carbon is now commonly used to effectively adsorb oxidized mercury, but the cost is too high, and how to dispose of the used activated carbon is also a problem.

[0003] An existing integrated energy-saving and emission-reduction device for a cement kiln has a patent publication number of CN218794633U. When the temperature of the cement kiln is high, cold water can be injected through a circulation pipe to cool the cement kiln. The water with a higher temperature can be stored in a water tank to facilitate subsequent heat preservation. At the same time, the parts to be dried are placed in a drying box for drying. The high-temperature gas in the cement kiln is sucked in by the fan and dries the parts. At this time, the motor can be turned on to drive the rotating rod to rotate. The rotating rod rotates, which in turn drives the first bevel gear to rotate. The first bevel gear rotates, which in turn drives the second bevel gear to rotate. The second bevel gear rotates, which in turn drives the mixing rod to rotate. The mixing rod rotates, which in turn drives the mixing blades to rotate, mixing the water in the water tank to make the water temperature balanced, which is convenient for heat preservation of the cement kiln.

[0004] However, drying requires continuous air circulation to remove moisture and achieve drying. However, the above-mentioned existing technology directly blows high-temperature gas to the parts to be dried, which may produce water droplets due to condensation, and harmful elements will still remain in the high-temperature gas, which can easily cause air pollution if directly discharged in large quantities.

High-temperature flue gas is discharged from the cement kiln body (1) into the exhaust pipe (2). Harmful impurities in the flue gas are removed by the dust bag (15). The refrigerator (26) cools the cooling pipe (27). The cooling pipe (27) transfers temperature through the heat conduction plate (28). When the high-temperature flue gas encounters the low-temperature heat conduction plate (28), condensation occurs, and water droplets condense on the heat conduction plate (28). S2, the output end of the first motor (35) drives the rotating screw (31) to rotate, the rotating screw (31) drives the threaded plate (32) to slide up and down, the threaded plate (32) drives the wiper (29) to slide up and down through the connecting rod (33) and the connecting plate (34), and the wiper (29) scrapes the water droplets on the heat conducting plate (28) into the water receiving bucket (3); S3, the first water pump (5) transports the condensed water from the water receiving hopper (3) and the connecting pipe (4) to the temperature exchange pipe (6), and the temperature of the water in the temperature exchange pipe (6) is increased by the temperature exchange of the high-temperature gas. The second water pump (7) then transports the heated water to the insulation pipe (8), thereby insulating the cement kiln body (1). The water then flows into the chemical tank (10); S4, the electric push rod (36) drives the connecting frame (37) to move, opens the sealing plate (38), and causes the chemical reagent in the reagent box (12) to flow into the chemical pool (10).
