PURPOSE: A freezing prevention apparatus of a waste water pipe and a waste water tank of a waste cleaning vehicle is provided to treat the waste water regardless of outside temperature in the winter season by preventing waste water from being frozen in the waste water pipe and the waste water tank. CONSTITUTION: A freezing prevention apparatus of a waste water pipe(20) and a waste water tank(10) of a waste cleaning vehicle is composed of a first heating unit(100), a second heating unit(200), a third heating unit(300), a heat generating unit(400), and a heat loss prevention unit. The first heating unit heats the waste water tank. The second heating unit heats the waste water pipe. The third heating unit heats a waste water auxiliary tank(30). The heat generating unit heats the heat transmitted to the first, second, and third heating units by using heat generated in an exhaust funnel of the waste cleaning vehicle. The heat loss prevention unit prevents the loss of heat generated in the heat generating unit. |
