Flue gas multi-effect bag type dust removal system

Abstract

The invention relates to the technical field of dust removal equipment, in particular to a flue gas multi-effect bag type dust removal system which comprises an incinerator, a urea injection device, a deacidification reaction tower, a sodium bicarbonate injection device, an activated carbon injection device, a dust remover, an SCR denitration device, an induced draft fan and a chimney. A smoke outlet of the incinerator communicates with a smoke inlet of the deacidification reaction tower through a pipeline. A smoke outlet of the deacidification reaction tower communicates with a smoke inlet of the dust remover through a pipeline, the smoke outlet of the deacidification reaction tower is located at the bottom, a smoke outlet of the dust remover communicates with a smoke inlet of the SCR denitration device through a pipeline, a smoke outlet of the SCR denitration device communicates with the induced draft fan, and the air outlet end of the induced draft fan communicates with the chimney through a pipeline. The activated carbon injection device and sodium bicarbonate injection device which are arranged in parallel communicate with the pipeline between the deacidification reaction tower and the dust remover. According to the invention, the dust removal efficiency is greatly improved, and the dust removal effect is improved.

Description

Technical field [0001] The present invention relates to the technical field of dust removal equipment, and more particularly to a flue gas multi-effect pocket dust removal system. Background technique [0002] With the increase in human production activities and social activities, especially since the industrial revolution, due to large amounts of fuel combustion, industrial waste gases and car exhaust emissions, the quality of the atmospheric environment is increasing, and my country has also been rapidly developed since the reform and opening up. However, the air quality is also deteriorated. Today, my country's environmental protection awareness has been strengthened. Whether it is a large-scale unit of private enterprises, a small unit of private enterprises, putting the protection environment in the first place, and work together to build a clean home. [0003] Glass melting is a high-temperature chemical reaction process, the exhaust gas is derived from the fuel combustion ...
