Smokeless and dust-removing drying oven having biomass as fuels and used for producing organic fertilizers

Abstract

The invention relates to drying ovens, particularly to a smokeless and dust-removing drying oven having biomass as fuels and used for producing organic fertilizers. The smokeless and dust-removing drying oven comprises a drying oven body which is directly connected with a drying cylinder. The drying oven body is 2-3m in height, 2.5-3.5m in length and 3-4m in width. The drying oven body is directly connected with the drying cylinder, a buffer segment is omitted, thus, during drying, dusts generated after the biomass burning are combined with organic fertilizer particles to achieve dust granulation. And meanwhile, heat loss is reduced so as to guarantee drying effect.

Description

(1) Technical field [0001] The invention relates to a drying furnace, in particular to a smokeless and dedusting drying furnace which takes biomass as fuel and is used for producing organic fertilizer. (2) Background technology [0002] In the production process of organic fertilizers, a drying process is required during the granulation process. In the past, standard coal was used as fuel in the drying process, and a large amount of dust was generated during the drying process, which not only polluted the environment, but also increased the production cost of the enterprise. . In order to change this situation, on the basis of practice, we have designed a method for manufacturing organic fertilizers that use biomass as fuel for smokeless and dust-free drying furnaces. (3) Contents of the invention [0003] The invention provides a smokeless dedusting drying furnace which uses biomass as fuel and is used for producing organic fertilizers with simple structure a...
