Design and Application of Heat Energy Recycling System in Broiler House
In order to effectively utilize the excess heat energy in the broiler house and solve the problem of odor pollution in broiler breeding,a heat energy recycling system was designed.The system was designed by air energy mechanism and electrocatalytic deammoniation process,and the heat recovery and deodorization effect of the system in the broiler chicken house were evaluated in Northeast China.Two sets of the same heat energy recycling system were used for ventilation in the experimental room,while negative pressure fan was used for ventilation in the control room.The results showed that the heat energy recycling system could increase the average temperature of fresh air by 2.19℃compared with the control house.The average concentrations of NH3 and CO2 decreased significantly by 0.91 and 272 mg/m3,respectively(P<0.05),the removal rate of NH3 reached 55.96%;and the heat recovery efficiency reached 64.00%.In conclusion,the system can effectively improve the temperature in the broiler breeding house,but reduce the concentration of NH3 and CO2 in the house;it has high efficiency of heat recovery and deodorization,and also has good effect of energy saving and emission reduction.
