Ammonia emission reduction device for livestock and poultry breeding house

Abstract

The invention belongs to the environmental protection field of animal husbandry, and provides an ammonia emission reduction device for a livestock and poultry breeding house. The device comprises filter wall combination equipment and a water pipe, the filter wall combination equipment comprises a frame, a gas distribution plate and a wet curtain, and the gas distribution plate and the wet curtainare installed in the frame; the gas distribution plate is provided with gas distribution holes, and the gas distribution holes comprise air holes, a baffle plate and a connection column; a spray pipeis arranged over the wet curtain and provided with a plurality of spray holes; the water pipe has two branches, which are respectively connected with the spray pipe and an atomization pipe; and the atomization pipe is arranged between the gas distribution plate and the wet curtain. The ammonia emission reduction device for the livestock and poultry breeding house provided by the invention can fully absorb ammonia gas in exhaust gas in the livestock and poultry breeding house, the absorption efficiency of the ammonia gas is very high, the emission of harmful gas is greatly reduced, air is purified, and the environment is protected; and the environmental conditions in the livestock and poultry house are greatly improved, the spread of diseases related to pollution is lowered, and the production efficiency and economic benefits are improved.

Description

technical field [0001] The invention belongs to the field of animal husbandry environmental protection, in particular to an ammonia emission reduction device for livestock and poultry breeding houses. Background technique [0002] Ammonia produced by large-scale livestock and poultry houses is one of the important sources of ammonia emissions in the atmosphere. Many studies have shown that ammonia is an important gas formed by PM2.5, which can be combined with SO in the atmosphere 2 and NO x Acidic substances such as ammonium salts are neutralized to form secondary particles such as ammonium salts, and these secondary particles have an important impact on the formation of haze. In recent years, Beijing has strictly implemented the national "Action Plan for Air Pollution Prevention and Control" and actively promoted the "Beijing 2013-2017 Clean Air Action Plan". There is still a big gap. Studies have shown that ammonium ions account for 11% of PM2.5 in Beijing's atmospher...

Problems solved by technology

In addition, part of the manure treatment area of ​​the farm is not covered with thatch, and it is returned to the field without decomposing treatment, which is also an important reason for ammonia emissions and surrounding air pollution.
