背景技术Background technique
鸡舍换气余热是指由鸡舍风机排出的空气所带的热量，包括大量显热和少量潜热。国内外大部分鸡场都直接把这部分热量排出舍外，造成了能源的浪费。如果将鸡舍换气余热用于鸡粪干燥，不但可以达到余热再利用的目的还能有效解决鸡粪处理难的问题。目前，利用鸡舍换气余热干燥鸡粪的技术在欧洲已经广泛应用，国内也已有少部分应用，但其设备都没考虑夏季湿帘开启时鸡舍排出的热空气湿度高和秋冬季节鸡舍排风量少、排风温度低等问题。为了加快干燥速度以减少氮的挥发造成空气污染和肥效降低，此时还需要额外热源的辅助。Chicken house ventilation waste heat refers to the heat carried by the air discharged by the chicken house fan, including a large amount of sensible heat and a small amount of latent heat. Most chicken farms at home and abroad directly discharge this part of heat outside the house, resulting in a waste of energy. If the waste heat from chicken house ventilation is used for drying chicken manure, it can not only achieve the purpose of waste heat reuse, but also effectively solve the problem of difficult chicken manure treatment. At present, the technology of drying chicken manure by using the waste heat of chicken house ventilation has been widely used in Europe, and a small number of domestic applications have also been used, but the equipment does not take into account the high humidity of the hot air discharged from the chicken house when the cooling curtain is opened in summer and the high humidity of the chicken in autumn and winter seasons. Problems such as low exhaust air volume and low exhaust air temperature. In order to speed up the drying speed to reduce the air pollution caused by the volatilization of nitrogen and the reduction of fertilizer efficiency, the assistance of an additional heat source is also needed at this time.

进一步的，太阳辐射传感器感应太阳能集热装置上的瞬时辐照值大于等于500W/m2时，打开送风风机的通风阀门，同时关闭压力舱风机的通风阀门，设施实施太阳能集热干燥鸡粪方法；当瞬时辐照值小于500W/m2时，打开压力舱风机的通风阀门，同时关闭送风风机的通风阀门，设施实施利用鸡舍余热干燥鸡粪方法。Further, when the solar radiation sensor senses that the instantaneous irradiance value on the solar heat collection device is greater than or equal to 500W/ m2 , the ventilation valve of the air supply fan is opened, and the ventilation valve of the pressure cabin fan is closed at the same time, and the facility implements solar heat collection to dry chicken manure. Method: When the instantaneous radiation value is less than 500W/m 2 , open the ventilation valve of the fan in the pressure chamber, and close the ventilation valve of the air supply fan at the same time, and implement the method of drying chicken manure by using the waste heat of the chicken house.
其中，除去特殊情况，太阳的瞬时辐照值均不低于500W/m2，太阳能集热干燥鸡粪方法可以正常实施，提高了干燥设施不同季节的适用性，两种方法切换，互补不足，提高了鸡粪干燥效率。Among them, except for special circumstances, the instantaneous irradiance value of the sun is not less than 500W/m 2 , and the method of drying chicken manure by solar heat collection can be implemented normally, which improves the applicability of drying facilities in different seasons. Improve the drying efficiency of chicken manure.
本发明提供的一种鸡粪干燥设施，通过排风风机和压力舱风机将鸡舍热空气用于干燥鸡粪，节约常规能源，对鸡粪的有效处理减少了氨气和粉尘的排放；送风风机将太阳能集热装置加热后的空气送至干燥室，并对鸡粪干燥，作为辅助热源，有效解决夏季鸡舍内热空气湿度高、秋冬季节鸡舍排风量少温度低的问题，选用绿色清洁的太阳能，与鸡舍热空气交替干燥鸡粪，缩短了鸡粪干燥时间，提高了干燥效率，减少鸡粪内氮的挥发，保证鸡粪的肥效。The chicken manure drying facility provided by the invention uses the hot air from the chicken house to dry the chicken manure through the exhaust fan and the pressure cabin fan, saves conventional energy, and effectively treats the chicken manure to reduce the discharge of ammonia and dust; The fan sends the air heated by the solar heat collector to the drying room, and dries the chicken manure. As an auxiliary heat source, it effectively solves the problems of high humidity in the hot air in the chicken coop in summer and low exhaust air volume and low temperature in the chicken coop in autumn and winter. The green and clean solar energy alternately dries the chicken manure with the hot air in the chicken house, shortens the drying time of the chicken manure, improves the drying efficiency, reduces the volatilization of nitrogen in the chicken manure, and ensures the fertilizer efficiency of the chicken manure.
