Technology for incinerating volatile organic gases and circulating fluidized bed incinerator utilizing technology

Abstract

The invention discloses a circulating fluidized bed incinerator of volatile organic gases, based on small aluminum oxidized hollow spheres as bed materials. The invention also provides a technology for incinerating the volatile organic gases by utilizing the circulating fluidized bed incinerator of the volatile organic gases. In the technology, the volatile organic gases enter a hearth from a gas inlet, and are burnt together with auxiliary fuel materials under the effects of the bed materials and a fluidized fan. The circulating fluidized bed incinerator of the volatile organic gases adopts small aluminum oxidized hollow spheres as the bed materials, the critical fluidized air speed of the circulating fluidized bed is lowered, thus the fluidized air quantity is lowered, and the circulating fluidized bed incinerator of the volatile organic gases has an energy-saving effect; and the volatile organic gases are incinerated at the high-temperature condition of 850-950 DEG C, and can achieve the combustion efficiency higher than 99.99%, and the aim of clean incineration and treatment is realized.

Description

technical field [0001] The invention relates to a circulating fluidized bed incinerator, in particular to a circulating fluidized bed incinerator for cleanly incinerating volatile organic waste gas and its incineration process. Background technique [0002] Organic waste gas is a common pollutant discharged from petrochemical, light industry, plastic, printing, coating and other industries. Organic waste gas often contains hydrocarbon compounds, oxygen-containing organic compounds, nitrogen-containing, sulfur, halogen and phosphorus-containing organic compounds, etc., such as benzene , toluene, styrene, polycyclic aromatic hydrocarbons and other volatile organic compounds (VOCs), etc. [0003] Volatile organic waste gas is one of the main air pollutants and is harmful to the human body. The common symptoms caused are fatigue, dizziness, headache, nausea and vomiting, palpitation, asthma, blood picture changes, etc., and aldehydes, amines and other substances also have stench...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the low concentration of volatile organic gases produced in industrial production and the low requirement for incineration air volume, while the existing circulating fluidized bed incinerator has a high bed material density and requires a large fluidization wind speed, which leads to the contradiction of large air volume. The invention provides a circulating fluidized bed incinerator suitable for volatile organic gas incineration with low fluidization wind speed
