Rotary drum and airflow mixed flow drying device for oil-tea fruit shell wastes

Abstract

The invention discloses a rotary drum and airflow mixed flow drying device for oil-tea fruit shell wastes. An air outlet of a primary rotary drum dryer is connected with a bigeminal cyclone dust collector, and the primary rotary drum dryer, the bigeminal cyclone dust collector, a quadrigeminal cyclone dust collector and a primary drying ventilator form a primary drying ventilation dust removal passage; a feed port of the primary rotary drum dryer is vertically connected with a primary drying feeder; the primary drying feeder is connected with a breaking device; a discharge port of the primary rotary drum dryer is connected with a secondary drying feeder; and the secondary drying feeder is connected with a secondary airflow dryer. The rotary drum and airflow mixed flow drying device has the advantages that: waste oil-tea fruit shells which are subjected to active ingredient extraction are dried by adopting rotary drum and airflow mixed flow to ensure that the water ratio of the waste oil-tea fruit shells is less than 18 percent and meets the requirement on oil-tea fruit shell granular fuel production.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying device for camellia oleifera husk waste with a drum and airflow mixing. Background technique [0002] Biomass is the solar energy fixed on the earth by the photosynthesis of plants, and the annual biomass produced by photosynthesis is about Ton, its energy is equivalent to about 10 times of the world's main fuel consumption; and its utilization as energy is less than 1% of its total amount. As energy, the world's utilization is mainly based on non-renewable energy such as coal, oil, and natural gas. Coal-fired power plants, industrial boilers, and civil boilers emit a large amount of sulfur dioxide and nitrogen monoxide into the atmosphere, which makes China's acid rain pollution problem increasing; coal combustion also produces a large amount of greenhouse gas CO 2 ; At the same time, a large number of dust emissions, resulting in a decline in air quality. The excessive developmen...
