| Summary: | 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.
