Fermentation tower water separation system

Abstract

The invention relates to a fermentation tower water separation system. A fermentation tower body (1) is fixed through a support frame (2); a feeding auger (3) is arranged on the axle line of the fermentation tower body (1); an annular water collecting groove (4) is formed in the fermentation tower body (1) and is positioned in a combination position of the middle part and the top of the fermentation tower body (1); a water outlet is formed in one side of the annular water collecting groove (4); one end of a water-steam conveying pipe (5) is connected with a water outlet of the annular water collecting groove (4); a precipitation cavity (7) is arranged at the bottom of the fermentation tower body (1); a water outlet of the precipitation cavity (7) is connected with a water collecting pool (8) through a pipeline. The fermentation tower water separation system has the advantages that through the annular water collecting groove and the precipitation cavity arranged in a fermentation tower, the water in the fermentation tower is discharged out of the tower; the material density is reduced; the fermentation speed is accelerated; in addition, the fermentation is more sufficient; harmful gas generated in the fermentation process is collected through the water steam collecting pool; the pollution is reduced.

Description

technical field [0001] The invention relates to the field of livestock and poultry manure treatment, in particular to a water separation system for a fermentation tower. Background technique [0002] During the fermentation process of the material (livestock and poultry manure) in the fermentation tower, due to the biological fermentation, the temperature of the material rises, and a large amount of water vapor is generated in the fermentation tower. Since the fermentation tower is a closed container, the water vapor cannot be discharged outside the tower, and it continues to accumulate. At the top of the tower, it will be dripped into the materials in the tower, which will increase the density of the materials and weaken the air permeability, which will seriously affect the fermentation effect of the materials, prolong the fermentation cycle, and even cause the fermentation of the materials to be incomplete. At the same time, part of the water will accumulate in the material...

Since the fermentation tower is a closed container, the water vapor cannot be discharged outside the tower, and it continues to accumulate. At the top of the tower, it will be dripped into the materials in the tower, which will increase the density of the materials and weaken the air permeability, which will seriously affect the fermentation effect of the materials, prolong the fermentation cycle, and even cause the fermentation of the materials to be incomplete. At the same time, part of the water will accumulate in the materials. The wall seeps to the bottom of the tower and flows out, causing the loss of material nutrients and causing some pollution to the environment
