碩士 === 國立中興大學 === 農業機械工程學系 === 86 === The layer houses with automatic water-pad environment controlhave been applied extensively by chicken-raising practitioners;however, the air pollution from their exhaust ports has beendeteriorating increasingly. To develop the chicken-raising industryeternally without affecting the environment conservation is one urgentproblem which need to be solved immediately . In order to exercise the simulation test indoors, we haveconducted this research in advance with designing and establishinga set of the simulation test mechanism for the air pollution treatmentinside the broiler house.In roder to proceed the test for the dust-removalfunction and to take the involved data of the wind speed, the pressuredrop, and the treatment effects of the filters ,etc., the culled materialsand filter systems were : the water-pad washing process, the cyclic spraynozzle washing process with light-masking net, the cyclone dust-removal(included the dry and wet) process, and the wave- form board washing process,etc. From these elementary test results, we could find the most efficientdust-removal process. According to the results analyzed from the synthetictests, as the instruments for the cyclic spray nozzle washing process withlight-masking net were set 50cm apart from the fan and the rotation speedof the fan reached 1640 rpm, the data of the dust- removal efficiency, thepressure drop, and the wind speed drop could be read in this order as: 77.87%,2.2 mm Aq , and 1.02 m/s. This is the best one of those four sets ofprocess as mentioned. We also exercised the research practically with setting up the spray nozzle washing process with light-masking net as mentioned in the practical layer house; and the test result is shown as bellow: asthe instruments for the spray nozzle washing process with light-masking netwere set 5 m apart from the fan and the rotation speed of the fan reached430 rpm, the data of the dust- removal efficiency, the pressure drop, andthe wind speed drop could be read in this order as: 84.26%, 6.9 mm Aq , and1.44 m/s. According to the test result, the air pollution treatment system withsetting up the spray nozzle washing process with light- masking net onto theexhaust port of the water-pad broiler house indeed efficiently achieve theeffects of the treatment for the treatment for air pollution.
