Abstract

The invention relates to the field of environmental protection management, in particular to a quenching absorption tower used for treating waste gas generated by recycling of hazardous waste inorganicsalts. The quenching absorption tower is characterized by comprising main parts of a quenching tower body, a quenching liquid spraying gun and a flue gas outlet-inlet. According to the quenching absorption tower, the mode that a calcium hydroxide emulsion is sprayed for direct cooling is adopted, thus flue gas flowing through the interior of the tower can make direct contact with sprayed-in liquid after atomization, the mass transfer speed and the heat transfer speed are quite high, the sprayed-in liquid is quickly vaporized to take away a large amount of heat, the temperature of the flue gasis quickly decreased to reach about 200 DEG C, and thus re-generation of dioxin substances is avoided; meanwhile, acidic components in the flue gas can be neutralized; and meanwhile, an anti-corrosion and high-temperature-resistant refractory material is adopted as the face, making contact with the flue gas, in the quenching tower body, wall sticking of alkali liquor and corrosion of equipment can be prevented, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the field of environmental protection treatment, in particular to a quenching absorption tower used for treating waste gas produced by recycling hazardous waste inorganic salts. Background technique [0002] After the hazardous waste is incinerated, a large amount of high-temperature flue gas will be produced. The quench tower is used to quickly cool down the high-temperature flue gas, so as to avoid the high-temperature flue gas from being directly discharged into the atmosphere and causing secondary pollution to the atmosphere. [0003] Sugarcane is one of the main raw materials for sugar production. About 50% of the fiber in bagasse left after sugar extraction can be used to make paper. Bagasse fiber length is about 0.65-2.17mm, width is 21-28μm. Although its fiber shape is not as good as wood and bamboo, it is slightly better than rice and wheat straw fibers. The slurry can be mixed with some wood pulp to make offset pri...
