Ammonia produced by large-scale livestock houses is one of the important sources of ammonia emissions in the atmosphere. Many researches show that ammonia is an important gas for forming PM2.5, and can react with SO in the atmosphere2And NOxAnd the like, to generate secondary particles such as ammonium salts and the like, and the secondary particles have important influence on the formation of haze. In recent years, the Beijing City is strictly implemented with the national air pollution prevention action plan, and the air cleaning action plan in 2013 and 2017 in the Beijing City is actively promoted, so that the air quality is obviously improved, but the air quality has a larger gap with the new national standard and public expectation. Research shows that the proportion of ammonium ions in the atmosphere in Beijing to PM2.5 reaches 11%, and the mass concentration of the ammonium ions in the air is obviously higher than that in non-polluted weather.

In practical use, the air containing ammonia in the livestock and poultry breeding house 10 is sent to the filter wall combination equipment 1 by the fan 7 through the sealing device 8. In the filter wall combination equipment 1, air containing ammonia firstly passes through the gas distribution plate 12, is decelerated and dispersed by the gas distribution plate 12, is uniformly distributed and enters a space between the gas distribution plate 12 and the wet curtain 13, and is fully mixed with the atomized ammonia absorption liquid sprayed from the atomizing nozzle 23 of the atomizing pipe 22, so that the ammonia is fully absorbed. The air containing ammonia then continues to travel to the wet curtain 13. The ammonia gas absorption liquid in the spray pipe 21 is sprayed out through the spray holes and moves from top to bottom from the top of the wet curtain 13 to cover the wet curtain 13 to form the wet curtain, so that the ammonia gas absorption liquid is fully contacted with the air containing the ammonia gas and reaches the wet curtain to further absorb the ammonia gas in the air.
Therefore, the air containing ammonia is redistributed by the gas distribution plate 12, so that the ammonia is absorbed for the first time by contacting with the atomized ammonia absorption liquid; then, the wet curtain 13 is used for absorbing ammonia for the second time, so that more than 90% of ammonia in the waste gas discharged by the livestock and poultry breeding house 10 is completely absorbed basically, and the absorption efficiency of the ammonia is very high, thereby greatly reducing the emission of harmful gas, purifying the air and protecting the environment; meanwhile, a large amount of ammonia absorption liquid is absorbed and can be recycled as a raw material for manufacturing the nitrogen fertilizer.
The utility model discloses an intelligent control device who sets up can also master in real time the humiture condition and the ammonia concentration in the house is bred to beasts and birds to the ammonia discharge current situation of key part of ability real-time supervision, in time regulation and control beasts and birds are bred and house in environment regulation and control device (fan) and ammonia collection processing facility (water pump) open and close, form scale plant ammonia and discharge intelligent monitoring technique, found digital system. And a feasible advanced technical means is adopted, the equipment quality is improved, the automation control and management level is improved, so that the simple operation is ensured, the later-stage operation is stable, the price is lower, and the method is particularly suitable for being used and developed in chicken farms.
The utility model discloses following beneficial effect can be obtained:
