Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] High-efficiency purification treatment method for waste incineration flue gas, the complete set of flue gas purification treatment includes: such as figure 1 As shown, flue gas pipeline system 1, spray reaction tower 2, lime slurry preparation system 3, activated carbon storage system 4, activated carbon injection system 5, filter bag dust collector 6, by-product delivery system 7, by-product storage bin 8 and induced draft fan 9.

[0038] The processing method consists of the following three steps:

[0039] Step 1: The flue gas from the waste heat boiler at about 190°C-240°C passes through the flue gas pipeline system 1 and enters the spray reaction tower 2 from the top. It is sprayed into the top of the spray reaction tower 2, so that the absorbent mist particles with a large surface area are in full contact with the flue gas, a strong chemical reac...

Abstract

The invention discloses a high-efficiency purification treatment method for waste incineration flue gas, and relates to the field of waste treatment. The purpose of the invention is to solve the problem that generated particulate pollutants cannot be effectively collected. The high-efficiency purification treatment for waste incineration flue gas is characterized in that a flue gas purification treatment integrated device comprises a flue gas pipeline system, a spray reaction tower, a lime slurry preparation system, an activated carbon storage system, an activated carbon injection system, a bag dust filter, a byproduct conveying system, a byproduct storage bin and an induced draft fan. The high-efficiency purification treatment method for waste incineration flue gas optimizes the purification treatment path of waste incineration flue gas and effectively prevents the problem that particulate pollutants generated after deacidification cannot be effectively collected.

Description

technical field [0001] The invention relates to garbage treatment, more specifically, it relates to a method for efficient purification and treatment of garbage incineration flue gas. Background technique [0002] Household garbage refers to the solid waste generated in the daily life of residents and discarded as having no value, mainly including organic matter and inorganic matter. Organic matter includes kitchen waste, paper, plastic, plant leaves, etc., while inorganic matter includes dust, glass, metal, etc. With the development of the economy and the improvement of people's quality of life, the amount of garbage collected has increased year by year, and the content of organic matter in it has continued to increase. [0003] Such a large amount of domestic waste has brought serious pollution to the environment in which people live. Includes air, soil, and water. threat to human health. Recycling and harmless treatment of domestic waste is an important issue that is ...
