Abstract

The invention relates to the field of environmental protection treatment, and specifically relates to a quenching absorption tower for treating waste gas produced by recycling hazardous waste inorganic salts. The invention adopts the method of direct cooling by spraying calcium hydroxide emulsion, which can make the flue gas flowing through the tower directly contact with the sprayed liquid after atomization, the mass transfer speed and heat transfer speed are very fast, and the sprayed liquid vaporizes rapidly Taking away a large amount of heat, the temperature of the flue gas can be quickly reduced to about 200°C, thereby avoiding the regeneration of dioxins; at the same time, it can neutralize the acidic components in the flue gas. At the same time, a kind of anti-corrosion and high-temperature-resistant refractory material is used as the contact surface between the inside of the quench tower body and the flue gas, which can prevent the lye from sticking to the wall and prevent equipment corrosion, prolonging the service life of the equipment.

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...
