Method and device for controlling air quality in henhouse of hen farm

Abstract

The invention relates to a method and device for controlling air quality in a henhouse of a hen farm. The method and device are characterized in that the method includes the following steps: (1) according to the hencoop arrangement characteristics, a bad air pipe is longitudinally installed on the surface of excrement of hens and communicated to the exterior of the henhouse to be connected with a draught fan, the draught fan is then connected with a washing tower, and a gas pollutant generated by the excrement is exhausted to be conveyed to the washing tower through the bad air pipe for centralized processing; (2) a fresh air pipe is longitudinally installed at the appropriate position equal to hencoops in height; in the transition season and in summer, the fresh air pipe is connected with an air blower outside the henhouse, and fresh air outside the hencoops can be directly conveyed to the interior of the henhouse through the fresh air pipe; in winter, the fresh air pipe is connected with a hot air furnace through an air heater outside the henhouse, and the fresh air outside the henhouse is heated by the hot air furnace to be conveyed to the interior of the henhouse through the fresh air pipe; (3) a pulverization system is installed at the position, close to the top end of the henhouse, right above the hencoops. The device comprises the bad air pipe, the draught fan, the washing tower, the fresh air pipe, the air blower, the air heater, the hot air furnace and the pulverization system.

Description

technical field [0001] The invention relates to an air quality control method and a device, in particular to a method and a device for controlling the air quality in a chicken house of a chicken farm. Background technique [0002] With the development of the times and the advancement of technology, people have higher and higher requirements for the health status of edible chickens such as broilers and laying hens, and the resulting requirements for air quality control in chicken houses are getting higher and higher. Traditional small chicken houses mostly use natural ventilation, and large-scale chicken farm chicken houses use certain mechanical ventilation to improve the environment in the house. However, the current ventilation methods often cannot fully and effectively control the air quality in the house, making the chickens The uneven distribution of air temperature, humidity, and pollutant concentration in the house, such as longitudinal ventilation, usually leads to l...

AI Technical Summary

Problems solved by technology

This method and system are beneficial to the improvement of the air quality in the chicken activity area, but the system uses the same pipe for air extraction and fresh air delivery. On the one hand, the residual pollutants in the public pipes will cause secondary pollution to the fresh air. On the other hand, The interval working method of the system cannot guarantee that the environment in the house can meet the health requirements of the chickens at any time, and the system does not take into account the adverse effects of the local accumulation of gas pollutants, temperature and humidity and other parameters in the ventilation flow field.
