Sludge wall-breaking dehydration and low-temperature negative-pressure drying system

The utility model relates to the technical field of sludge treatment, in particular to a sludge wall-breaking dehydration and low-temperature negative-pressure drying system which comprises a wall-breaking conditioning tank, the wall-breaking conditioning tank is simultaneously connected with a dosing device and an ozone generator, the wall-breaking conditioning tank is connected with a plate-and-frame filter press, one end of the plate-and-frame filter press is connected with a heat exchange squeezing water tank through a squeezing water pump, and the other end of the plate-and-frame filter press is connected with a water pump. The heat exchange squeezing water tank is connected with the air energy water heater which is connected with the other end of the plate-and-frame filter press. According to the system, sludge dewatering and drying are synchronously realized, the sludge treatment cost is greatly reduced, the sludge treatment efficiency is improved, meanwhile, the VOCs gas pollution phenomenon in the sl
