Embodiment

[0057] Further description will be given below through the embodiments shown in the accompanying drawings.

[0058] The ventilation system of this embodiment includes a ventilation control device, a temperature control device and a ventilation device. The ventilation device also includes ventilation ducts, chain plates, steel plates, air outlets and fans. The structure of each component in this embodiment is similar to that of the above-mentioned embodiment.

[0059] The chain plate and steel plate (with no small holes on the steel plate) under the pile body form a closed space with the bottom of the composting reactor, and the ventilation pipe is located in this closed space. The air outlet is located above the stack. After the ventilation system is started, the airflow enters the stack through the small holes on the chain plate, exchanges heat and gas with the stack, and then flows out through the air outlet above the stack.

[0060] The air duct includes a main pipe and ...

Abstract

The invention relates to a uniform ventilation system for a compost reactor. The ventilation system comprises a ventilation device, a ventilation control device and a temperature control device, the ventilation device comprises a fan, a ventilation pipeline and an air outlet, the ventilation pipeline is arranged below the compost reactor, and ventilation holes are formed in the ventilation pipeline; the air outlet is formed above the compost reactor; the fan is arranged at the inlet of the ventilation pipeline; the ventilation control device comprises a frequency converter, a flow meter and afirst controller, the frequency converter is connected with the fan and the controller, the flow meter is arranged on the ventilation pipeline and connected with the controller, and the controller calculates the speed of airflow in the ventilation pipeline according to the ventilation flow measured by the flow meter and controls the frequency converter; and the temperature control device comprisesa thermometer, a heater and a second controller, the probe of the thermometer is mounted in the compost reactor, the thermometer is connected with the second controller, and the second controller isconnected with the heater. The air inlet temperature, and the air outlet angle and the air outlet speed of small holes in the air pipe can be controlled.

Description

technical field [0001] The invention relates to the technical field of composting ventilation, in particular to a uniform ventilation system for a composting reactor. Background technique [0002] Ventilation is one of the important factors affecting the effect of composting, which can provide oxygen to the heap and take away moisture and heat. When the inlet air temperature is too low, the ventilation will take away too much heat inside the pile, and the composting reaction cannot proceed normally. When the air supply is insufficient, the heap will undergo anaerobic fermentation. Therefore, in order to achieve a good composting effect, the control of the inlet air temperature and the reasonable design of the ventilation system are particularly important. [0003] Ventilation system design mainly includes ventilation volume selection, ventilation duct design, etc. The research on the ventilation rate has been relatively mature, and the ventilation pipes that play a major ...
