Abstract

A light calcium carbonate chaff burning furnace heat supply and flue gas treatment device, including a light calcium carbonate filter cake drying device, a drying hot air pipe is arranged in the light calcium carbonate filter cake drying device, and the drying hot air pipe is connected to The hot air supply pipes of the hull combustion furnace are connected, and the drying hot air of the light calcium carbonate filter cake drying device is produced by the chaff combustion furnace. The hot air is sent to the hot air pipe of the drying box through the hot air supply pipe; the drying heat The outlet of the air duct is connected to the flue gas dust removal treatment device. After the hot air work is completed, it will enter the flue gas dust removal treatment device for treatment, and will be discharged through the flue after reaching the standard. The present invention uses the chaff burning furnace to produce hot air and sends it to the drying box through the hot air supply pipe to dry the light calcium carbonate filter cake. Reduced the energy consumption for drying the light calcium carbonate filter cake.

Description

technical field [0001] The invention relates to a light calcium carbonate production device, in particular to a heat supply and flue gas treatment device for a light calcium carbonate chaff combustion furnace, the heat supply and flue gas treatment device for a light calcium carbonate chaff combustion furnace The invention is more energy-saving, environment-friendly, resource-saving, and realizes intelligent control, and belongs to the technical field of light calcium carbonate production. Background technique [0002] Light Calcium Carbonate (Light Calcium Carbonate) is also called Precipitated Calcium Carbonate (PCC for short).
