Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to an energy-saving circulating heating system for boiler water used in feed production. Background Art

[0002] The energy-saving circulating heating system for boiler water used in feed production is a system specially designed for boiler water used in the feed production process. Its purpose is to efficiently increase the water temperature while minimizing energy consumption. It is mainly based on the principle of hot water recycling. After the boiler heats the water, the hot water is transported through pipes to the equipment that requires heat in the feed production process. After releasing heat in these equipment, the water temperature drops and then returns to the boiler through the return pipe for reheating, and the cycle repeats.

[0003] After searching, the Chinese patent announcement number is: CN209084744U, which discloses a boiler system for feed production, including a feed hopper, a burner and a boiler connected in sequence. The top of the feed hopper is connected to an auger feed pipe through a motor, and the auger feed pipe extends to the storage bin; an air distribution device is provided on the inside of the burner, and the air distribution device includes a main air duct, a protective cover and an air distribution plate. The air distribution plate is symmetrically arranged in a reverse tangential manner and arranged on the outer wall of the main air duct. A protective cover is mounted on the top of the air distribution plate, and an air distribution cavity is formed between the air distribution plate and the protective cover; a ventilator is provided on the outer side of the burner, and the ventilator and the main air distribution device are connected to the ventilator. The air ducts are connected, and the ventilator can guide the airflow into the burner quickly and effectively. The guide blade structure is stable and the guide efficiency is high. The air distribution device ensures that the airflow enters the burner in an even distribution, ensuring the supply of oxygen in the burner, thereby improving the combustion efficiency. The steam produced by the boiler can be used for feed production, ensuring the processing quality of the feed and reducing costs. Since natural gas is used to heat the boiler, the steam of the heating medium still retains a large amount of waste heat after heat exchange. At the same time, the flue gas generated by the boiler combustion also has a large amount of thermal energy, and directly releasing it will cause serious heat loss. Utility Model Content
