Intelligent heat recovery device and method for livestock breeding

Abstract

The invention discloses an intelligent heat recovery device and method for livestock breeding. The heat recovery device comprises a liquid storage box set, a water pump and a fan. The liquid storage box set comprises an upper liquid storage box and a lower liquid storage box, and multiple waste liquid through holes are formed in the bottom of the upper waste liquid box and the top of the lower waste liquid box. Multiple waste liquid channels and multiple air channels are arranged between the upper waste liquid box and the lower waste liquid box, and the multiple waste liquid channels and the multiple air channels are arranged at intervals. The multiple air channels are transversely arranged, and the exhaust ends of the air channels are connected into a breeding room through an air guide channel. Liquid flow velocity sensors are arranged on the waste liquid channels, and gas flow velocity sensors are arranged on the air channels. According to the intelligent heat recovery device and method for livestock breeding, heat of waste liquid discharged out of the breeding room can be fully utilized, heat recycling is achieved, the air temperature and flow velocity in the breeding room can be intelligently adjusted, livestock growth is facilitated, and the indoor environment is kept clean.

Description

technical field [0001] The invention relates to livestock breeding processing equipment, in particular to an intelligent heat recovery device and method for livestock breeding. Background technique [0002] At present, the scale of the livestock breeding industry is getting larger and larger, and the requirements for indoor ventilation during the breeding process are also getting higher and higher. Among them, a good ventilation system can not only improve the indoor air quality of the breeding, but also effectively prevent the epidemic. Therefore, the farm The ventilation system inside is of great significance to the health of livestock and the breeding environment. The ventilation system mainly includes a heat exchanger. The heat exchanger is connected to the liquid discharge port in the deodorization equipment, and the livestock liquid with a certain temperature flows through the heat exchanger, so that the air in the heat exchanger absorbs heat and then discharges.

Problems solved by technology

[0003] The temperature range suitable for the growth of livestock and poultry in the breeding room is constant, but the temperature of the indoor waste liquid varies greatly throughout the year. If the flow rate of gas and liquid in the heat exchanger is always constant, it will lead to If the temperature of the gas cannot meet the needs of farming, it is necessary to manually adjust the flow rate of gas and liquid in the heat exchanger to meet the needs of farming

However, manual adjustment has a certain hysteresis, and workers often find out that the indoor temperature is not within the specified temperature range, which affects the normal growth of poultry and livestock and the breeding environment
