Water curtain box for ammonia absorption in livestock and poultry houses

Abstract

The invention belongs to a water curtain box for ammonia gas absorption of a livestock breeding house. The water curtain box comprises a box body and a water curtain box base arranged at the bottom of the box body, the box body is provided with front aerating plates and lateral aerating plates, a water inlet and a water outlet are arranged below the lateral aerating plates, the bottom of the box body is provided with a water sink, an annular water channel is arranged on the periphery of the water sink, wet curtain plates are arranged in the annular water channel, an annular water pipe is arranged on the upper sides of the wet curtain plates, the bottom of the annular water pipe is provided with water holes, and an axial fan, a floater switch and an air cooler water pump are arranged at the inner bottom of the box body. The water curtain box base comprises a bottom plate, vertical plates and surface plates. The wet curtain plates are arranged on the periphery of the water curtain box, water in the water sink cyclically flows in the wet curtain plates via the axial fan and the air cooler water pump, ammonia gas is repeatedly absorbed, concentration of the ammonia gas in the breeding house is effectively reduced, growth speed and feed conservation ratio of livestock are increased, disease rate of the livestock is decreased, cost of enterprises is saved, and environmental pollution caused by discharge of the ammonia gas is avoided.

Description

technical field [0001] The invention belongs to an ammonia absorbing device, in particular to a water curtain box used for absorbing ammonia in livestock and poultry breeding houses. Background technique [0002] The scale of the breeding industry has continuously increased the stocking density, which has brought about an increase in ammonia emissions per unit area. After ammonia gas enters the blood, it reduces the amount of dissolved oxygen in the blood and reduces the resistance of livestock and poultry. Long-term exposure to ammonia gas concentration of 10-15ppm will significantly reduce the stress resistance of animals. The aqueous solution of ammonia gas is alkaline and irritating to mucous membranes, which can cause tearing and burning eyes, inflammation of cornea and conjunctiva, and visual disturbance. High concentrations of ammonia can cause symptoms such as coughing, bronchitis, pulmonary edema, hemorrhage, and suffocation. In addition, ammonia can increase the ...

Problems solved by technology

[0004] Although these research results have reduced the ammonia content in livestock and poultry breeding houses to a certain extent and purified the air quality in livestock and poultry breeding houses, they are not suitable for Popularization and application in small and medium-sized livestock and poultry breeding houses and small family breeding houses

Most of the existing livestock and poultry breeding houses still use the characteristics that the density of ammonia gas is lower than that of air, it is distributed on the upper part of the livestock and poultry breeding houses, and it is easily soluble in water. The ammonia gas is absorbed by the ammonia absorption device, while the existing ammonia Most of the absorption devices use a single-layer wet curtain to absorb ammonia gas, which cannot fully absorb ammonia gas. The water circulation system for collecting ammonia gas is poor, and cannot continuously absorb ammonia gas in poultry breeding houses. In addition, ammonia gas collection is not easy to operate and control. High production and maintenance costs, especially in winter, the ammonia concentration in livestock and poultry breeding houses is still high, which seriously affects the ammonia removal effect, and cannot meet the requirements of low ammonia content in modern livestock and poultry breeding houses
