Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figure 1, including bio-trickling filter master the utility model discloses a kind of bio-trickling filter that humidity is controllable
Body, circulation humidification component, humid control component and dosing tank 12, bio-trickling filter main body are multilayer laminar structure, from top to bottom
Respectively exhaust level 1, biology aerobic process layer 2, humidification layer 3, bio-trickling layer 4, air inlet layer 5 and medical fluid layer 6 lead between each layer
It crosses detachable filter plate and carries out physical separation, circulation humidification component one end is connected with medical fluid layer 6, and the other end is set in humidification layer 3,
Humid control component is set in humidification layer 3, is connected by electrical connection with circulation humidification component, dosing tank 12 is installed on medical fluid
The side of layer 6 is connected with medical fluid layer 6.
