最近，加利福尼亚州的一个养鸡场的三层山房子起火了。火非常激烈。火灾正在飙升，烟雾滚动，整个鸡舍崩溃了。施加了280,000只鸡的280,000只鸡被施走了。事实上，在美国的养鸡场的火灾事故并不少见。例如：2017年7月，美国在美国宾夕法尼亚州养鸡场席卷了一座火灾，导致超过100,000层母鸡活着，并造成重大损失;2020年1月4日，西南密歇根州的建筑物在家禽养鸡场爆发，大约300,000名母鸡被烧死了。

1. What is the cause of the accident?

Judging from the picture, the chicken coop area is not large, but there are nearly 300,000 chickens in captivity inside, which is unbelievable! For a long time, some large chicken farms have been driven by interests, and the overloaded captivity of chicken coops has been criticized by American society.

2. Why do fires occur in chicken houses that are overloaded?

The most likely fire risk point is that combustible gases such as ammonia and hydrogen sulfide exceed the standard. Both of these gases are flammable and explosive and will detonate immediately when they reach a certain concentration in the air. However, the lower explosion limit of ammonia is 15% and hydrogen sulfide is 4.3%. Therefore, it is not easy to reach the gas concentration required for explosion. So where is the high concentration of ammonia and hydrogen sulfide in the chicken house?

(1) Waste such as feces and feathers

鸡舍拥挤，数万，甚至数十只鸡。如果房子未及时清理清理，则鸡的粪便和羽毛易于分解和恶化，其被微生物分解以产生氨气和硫化氢。这两者都是可燃气体，因此并不难以想象成千上万的鸡在鸡舍中被置于鸡舍，它们的粪便将产生超高浓度的可燃气体。

（2）床垫

The cushions laid in the chicken coop are generally made of sawdust, sawdust, grass and other highly absorbent materials. When the temperature and humidity in the chicken house are too high, the mat will absorb a lot of water and become very humid, accelerate the rotting of chicken manure, and cause the concentration of ammonia and hydrogen sulfide to rise rapidly in a short time.

(3) Ventilation facilities

According to the local weather forecast, the lowest temperature in California is 12 degrees Celsius. Some chicken farms are worried that the chickens will be affected by cold and freezing, which will affect the production. Therefore, they cannot do enough ventilation and ventilation, which will increase the concentration of combustible gas.

In summary: chicken manure, chicken house bedding, and ventilation in the chicken house are all important risk points for fire and explosion. Of course, there are other fire risk points in the chicken house, such as dust explosions such as dust and feed debris.

3.如何处理隐患并防止他们发生？

如何应对鸡粪和其他牲畜和家禽，从农场废物的粪便，以及改善笔环境？

Manure treatment equipment can effectively solve the waste disposal problems faced by aquaculture plants; organic fertilizer pellet production lines and supporting facilities have truly realized the theme of turning waste into nutrients.

What is manure treatment equipment? How to realize the production process of organic fertilizer particles from manure to chicken farm?

(1)  Compost fermentation 

Collect all kinds of livestock and poultry manure for production and living, and mix them according to a certain ratio after pretreatment. The humidity of the mixture is about 60% (humidity suitable for fermentation). Add biological strains to make it ferment. Faster and more complete. 

(2) Crushing: The crushing object is the material after the fermentation is completed, the humidity is relatively dry, in order to meet the requirements of granulation, the output particle size should be less than 0.5mm, the finer the easier the granulation.

(3) Screening of materials:

A . sieve out all the fine materials as much as possible;

B.将细材料直接筛到下一步; 

C. collect the screened slag and crush it again.

(4) Mixing: According to the requirements of the new organic fertilizer pellet makingmachine, the moisture of the material is adjusted, generally between 30% and 35% , both to ensure the molding and the production speed. 

(5)造粒:颗粒大小均匀,molding rate is high, and it must meet the output requirements.

(6) Drying: The prepared chicken manure organic fertilizer pellets are transported to the dryer, and the fertilizer is dried by using the large air volume produced by the fan and the temperature after being treated by the jet air inducer. 

(7)冷却:成品球团矿运输to the organic fertilizer cooler, and the fertilizer is cooled by natural cold wind or strong cooling wind.

(8) Screening of particles: Too small or too large pellets will return to the previous stage to re-granulate.
