Abstract

Provided is a heat supply and flue gas treatment method adopting a light calcium carbonate chaff combustion furnace. The chaff combustion furnace is adopted in a light calcium carbonate drying processto make hot air, a dehydrated light calcium carbonate filter cake is dried, dried chaff smoke is subjected to dust removal treatment through a water curtain, and a clean production effect is achieved. A heat supply and flue gas treatment device adopting the light calcium carbonate chaff combustion furnace comprises a light calcium carbonate filter cake drying device, wherein a drying hot air pipeis arranged in the light calcium carbonate filter cake drying device and is communicated with a hot air supply pipe of the chaff combustion furnace, drying hot air of the light calcium carbonate filter cake drying device is the hot air made by the chaff combustion furnace and is delivered to a drying box hot air pipe through the hot air supply pipe. An outlet of the drying hot air pipe is connected with a smoke dust-removal treatment device, hot air enters the smoke dust-removal treatment device for treatment after work is completed and is discharged out through a flue after the standard is reached.

Description

technical field [0001] The present invention relates to a light calcium carbonate production method and device, in particular to a light calcium carbonate chaff combustion furnace heat supply and flue gas treatment method and device, the light calcium carbonate chaff combustion furnace heat supply and The flue gas treatment method and device are more energy-saving, environmentally friendly, resource-saving, and realize intelligent control, belonging 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).
