The invention discloses a sampling and collecting device of a
human settlement environment
fresh air introduction
system, which comprises a
system air
pipe and a fixing frame arranged on one side of the outer wall of the air
pipe, a sampling
assembly is cooperatively arranged on the inner wall of the
system air
pipe close to the front end of the system air pipe, and one end of the sampling
assembly is detachably connected with a filtering
assembly. The rear end of the filtering assembly is detachably connected with a condensation dehumidification assembly, the rear end of the condensation dehumidification assembly is detachably connected with a three-way flow dividing pipe, the vertical end of the three-way flow dividing pipe is a particulate matter collecting
branch, the other horizontal end of the three-way flow dividing pipe is a VOCs collecting
branch, and the rear end of the VOCs collecting
branch is detachably connected with an
activated carbon adsorption pipe. A control assembly is arranged between the two ends of the three-way flow dividing pipe and one side of the rear end of the outer wall of the system air pipe in a matched mode, a control cabinet is arranged on one side of the upper end of the fixing frame, and a control panel, a
wireless communication module and a
voltage stabilizing module are installed in the control cabinet. When the
fresh air environment is sampled, multi-point sampling can be achieved, interference of dust and
water vapor can be reduced, and the sampling efficiency is improved.
