Embodiment 1

[0017] A treatment method for waste incineration tail gas, comprising the following steps:

[0018] (1) The flue gas in the waste incinerator passes through the cooling pool, and the flue gas is cooled in the cooling pipe in the cooling pool, so that the temperature drops rapidly below 130°C, and then it is removed by the bag filter under the action of the induced draft fan Most particulate dust and dioxins;

[0019] (2) remaining flue gas enters the first purification pond containing quicklime water, wherein the weight ratio of each component of the liquid in the first purification pond is: the water of 800kg, the quicklime of 3kg;

[0020] (3) The flue gas after the treatment of the first purification tank enters the second purification tank containing quicklime water, wherein the weight ratio of each component of the liquid in the second purification tank is: 800kg of water, 3kg of quicklime;

[0021] (4) The flue gas after the treatment of the second purification tank ent...

Abstract

The invention discloses a method for treating garbage incineration tail gas. The method comprises the following steps of enabling smoke in a garbage incinerator to pass through a cooling pond; cooling down the smoke in an annular tube in the cooling pond until the temperature of the smoke is rapidly reduced to be 130-150 DEG C; enabling the cooled smoke to pass through a first purifying pond with quick lime water and a second purifying pond with quick lime water sequentially; then enabling the smoke to pass through a third purifying pond with activated carbon; and discharging the smoke after the smoke is purified by water in the three ponds. A three-stage chilled water washing technology is adopted in the method for treating the garbage incineration tail gas; equipment is simple and practical; the method is effective and energy-saving; emission of harmful pollution gas can be greatly reduced; and emission of pollution gas such as dioxin, smoke, carbon monoxide and sulfur dioxide conforms to a national emission standard.

Description

technical field [0001] The invention relates to the field of harmful gas reprocessing, in particular to a method for processing waste incineration tail gas. Background technique [0002] Waste incineration technology is being increasingly widely used due to its advantages of high volume reduction rate and recyclable heat energy. Like the combustion process of coal, wood and other fuels, waste incineration will also produce smoke. Due to the complexity of waste components, the smoke produced by incineration contains many harmful substances and has special properties. In recent years, the problem of dioxin and heavy metal pollution from waste incineration has attracted increasing public attention. For this reason, the State Environmental Protection Administration promulgated the "Standards for Pollution Control of Domestic Garbage Incineration" (GB18485-2001), which strictly restricts the emission indicators of waste incineration flue gas. Traditional waste incineration tail...
