Embodiment 1

[0058] Example 1 The absorption bottle used in the laboratory is used, and 200ml of modified silicone oil is filled in the absorption bottle, and the exhaust gas of a kiln that uses petroleum coke as raw material to produce 800 tons of glass per day is directly collected from a kiln exhaust gas of a group in Huzhou, Zhejiang, and is dedusted by a bag filter. On the final pipeline, exhaust gas was extracted for dust removal test; 1Nm 3 The exhaust gas passes through the absorption bottle and is absorbed by the 200ml modified silicone oil in the absorption bottle; the 200ml modified silicone oil that has absorbed the dust is subjected to centrifugal separation. Then there is the water layer, then the solid organic layer, and the top layer is the modified silicone oil layer; after drying and weighing, the weight of the ash layer is 2.3546g, and the weight of the solid organic layer is 0.3213g, so the glass kiln after bag dust removal The content of dust and organic matter in the ...

Embodiment 2

[0059] Embodiment 2 adopts the absorption bottle used in the laboratory, and puts 200ml of peanut oil and modified silicone oil mixture into the absorption bottle, directly from a kiln tail gas of a group in Hainan that uses natural gas as raw material to produce 600 tons of glass per day, after denitrification and On the pipeline after alkaline desulfurization, exhaust gas was extracted for dust removal test; 0.6Nm 3 The exhaust gas passes through the absorption bottle and is absorbed by the 200ml mixture of peanut oil and modified silicone oil in the absorption bottle; the 200ml mixture of peanut oil and modified silicone oil that has absorbed dust is subjected to centrifugation, and after centrifugation, it is divided into three layers in the centrifuge tube : The bottom is the ash layer, followed by the water layer, and the uppermost layer is the mixed liquid layer of peanut oil and modified silicone oil; the weight of the ash layer after drying and weighing is 0.5347g, so ...

Abstract

The invention discloses a waste gas dust removing method and a dust removing agent. According to the method, dust-containing waste gas and an organic dust removing agent enter a dust removing tower respectively and are in contact with each other in the tower; at least partial water steam in the dust-containing waste gas is condensed, and the organic dust removing agent and condensed water are used for adsorbing solid particles, acidic pollutants, organic pollutants and / or heavy metal compounds in the dust-containing waste gas; and purified air is emptied or enters a subsequent process. The organic dust removing agent comprises toxin-free and high-boiling-point organic solvent compositions which are selected from two or more of edible oil, silicone oil, modified silicone oil, liquid-state asphalt oil, tung tree seed oil, liquid-state paraffin wax oil, mineral oil, palm oil and illegal cooking oil. By virtue of the method, dust (including PM100, PM10, PM2.5, relatively small particles and the like) in the waste gas can be effectively removed, and HCl, HF, dioxin, polycyclic aromatic hydrocarbon, other organic matters, heavy metal compounds and the like in the waste gas can be removed.

Description

technical field [0001] The invention relates to the technical field of waste gas dedusting, in particular to a method, equipment and dedusting agent for flue gas or various combustion tail (waste) gases. Background technique [0002] Fossil fuel combustion produces a large amount of flue gas that is discharged into the atmosphere. In addition to sulfur dioxide, sulfur trioxide, hydrogen chloride, hydrogen fluoride, nitrogen oxides, a small amount of harmful organic substances and heavy metal compounds, the flue gas also contains a large amount of dust. Including tiny hydrophilic and lipophilic particles, wherein the tiny hydrophilic and lipophilic particles mainly include calcium salt particles, aluminum salt particles, magnesium salt particles, titanium salt particles, iron salt particles, lead salt particles, zinc salt particles particles, cobalt salt particles, rare earth element particles, radioactive element particles, and other harmful element particles, as well as min...
