Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a spray washing tower cleaning device for a rotary kiln. Background Art

[0002] A rotary kiln refers to a rotary calcining kiln (commonly known as a rotary kiln), which belongs to the category of building materials equipment. It is a cylindrical equipment placed horizontally or tilted. Through its rotating motion, the materials are evenly heated and mixed in the kiln. According to different process requirements, rotary kilns can be divided into many types, such as cement rotary kilns, metallurgical rotary kilns, chemical rotary kilns, etc. The working principle of the rotary kiln is: the raw materials are evenly fed into the upper part of the rotary kiln through the feeding device. As the kiln body rotates, the raw materials gradually descend and advance along the length of the kiln. At the bottom of the kiln, the burner injects fuel (such as coal powder or natural gas) to form a high-temperature flame. The flame transfers heat to the raw materials through the kiln barrel, heating the raw materials to a certain high temperature, thereby undergoing physical or chemical reactions, such as the formation of clinker. After that, the clinker moves toward the outlet of the kiln barrel, is cooled by the outside air during the movement, and is finally discharged from the outlet of the kiln.

[0003] A spray scrubber, also known as a spray tower or a washing tower, is an environmentally friendly waste gas treatment equipment, mainly used to treat inorganic waste gases, such as sulfuric acid mist, hydrogen chloride gas, NOx (nitrogen oxide gas in different valence states) and dust waste gases. The spray scrubber purifies the gas by making the waste gas fully contact with the liquid and using the solubility of the waste gas in water or chemical reaction to reduce its concentration. The structure of the spray scrubber mainly includes a tower body, a filling layer, a spray layer, a demisting layer, a circulating sprinkler pipeline, a circulating water tank, an air inlet, an air outlet, etc. Among them, the spray layer mostly uses solid medicine balls or ceramic fillers to increase the gas-liquid contact area and mass transfer efficiency. When treating acid and alkaline gases, not only should a neutralizing agent be added to the water pool, but the filler balls should also use acid and alkaline medicine balls to improve the neutralization efficiency and achieve the purpose of neutralizing the acid and alkaline gases.
