Embodiment Construction

[0020] see Figure 1 to Figure 3 , an air purification device for removing ammonia in a pickling water curtain type pig house includes a purification and filtration system, an ammonia collection and recovery system, an air inlet and outlet system, an acid water circulation system, and a control system. The purification and filtration system consists of the first-stage pickling water curtain 9, the second-stage pickling water curtain 10, the activated carbon filter layer 8, the pickling water curtain bracket 12, and the activated carbon filter layer bracket 13. The first-stage pickling water curtain 9 1. The second-stage pickling water curtain 10 adopts a sparser cloth material and has an uneven surface to increase the contact area between the acid water and the air. The activated carbon filter layer 8 has a honeycomb structure; the ammonia gas collection and recovery system It is mainly composed of acid water outlet 15, acid water recovery pipeline 24, acid water recovery pump...

Abstract

The invention provides an acid-cleaning water curtain type ammonia-removal air purification device in a pig house. The device comprises a purification filter system, an ammonia collection and recoverysystem, an air inlet and outlet system, an acid water circulation system and a control system. By adoption of the device, a multistage hierarchical acid water curtain and an activated carbon filter layer are formed, air in the pig house is led into the device through a fan and passes through the acid water curtain and the activated carbon filter layer to effectively reduce the ammonia concentration, and then the purified air is exhausted out of the pig house. Therefore, ammonia collection and acid water recycling are both realized, and by repeating the cycle, reduction of internal ammonia concentration of the pig house, air purification, reduction of frequency of air exchange between the pig house and the outside and reduction of heat loss are realized.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding, and is an air purification device for removing ammonia in a pickling water curtain type pig house. Background technique [0002] In intensive pig production, due to the high density of pig farms, especially the poor air quality in closed pig houses in winter in northern cold regions, ammonia (NH 3 ) and other harmful gases have a high concentration, which seriously affects the growth and health of pigs. Ammonia is mainly produced by microbial decomposition of feed residues and feces in pig houses. Ammonia has a strong pungent odor and is easily soluble in water and acid. It is one of the important pollutants in the environment of pig houses. NH in the pig house 3 Adsorbed or dissolved on the surface of pig mucosa and wet surface in the house, NH 3 It can combine with hemoglobin through the respiratory system, reduce the oxygen carrying capacity of the blood, and low concentration ...
