Abstract

The invention relates to the technical field of livestock and poultry manure treatment, and provides a facility and a method for treating chicken manure through combination of drying and sterilization. The facility comprises a chicken coop, a drying room and a boiler; the chicken coop is communicated with the drying room through a ventilation corridor, the boiler is communicated with one end of awater outlet pipe, one end of the water outlet pipe is connected with a water inlet of a heat exchanger, a water outlet of the heat exchanger is connected with one end of a water return pipe, the other end of the water return pipe is communicated with the boiler, and the heat exchanger is arranged in the drying room. The method includes the steps of leading the air exchange residual heat in the chicken coop into the drying room through the ventilation corridor, and drying the chicken manure in the drying room; leading hot water in the boiler into the heat exchanger, and sterilizing the chickenmanure in the drying room by hot air generated by the heat exchanger. The facility and the method provided by the invention have the advantage that the chicken manure is treated by the combination ofdrying and sterilization, the drying efficiency is improved, the cost is reduced, and the safety of the manure is guaranteed.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment, in particular to a facility and method for combining drying and sterilization to treat chicken manure. Background technique [0002] The waste heat of chicken house ventilation refers to the heat (including a large amount of sensible heat and a small amount of latent heat) carried by the exhaust gas discharged by the fan of the chicken house. Using the waste heat of chicken house ventilation to dry chicken manure can save a lot of conventional energy, and can also use chicken manure Absorbs dust and odors from the house exhaust. After many chicken farms in my country introduced this technology, due to the hot summer and cold winter in most areas of our country, and the frequent impact of cold air in spring and autumn, there have been many problems in the practical application of this technology, for example, the wet curtain of the chicken house in summer When the ch...
