Rotational flow thermal vibration drying machine and rotational flow thermal vibration drying system

Abstract

The invention relates to the technical field of wet sludge drying, in particular to a rotational flow thermal vibration drying machine and a rotational flow thermal vibration drying system. The rotational flow thermal vibration drying machine comprises: a hollow drying chamber, wherein one end of the drying chamber is provided with a feeding port and an air inlet, and the other end of the drying chamber is provided with a discharging port; a heat source jacket which is arranged around the outer side of the drying chamber, wherein a medium serving as a heat source circulates in the heat source jacket, and a heat source outlet and at least one heat source inlet are formed in the heat source jacket; a rotating shaft which is arranged in the middle of the drying chamber and penetrates through the two ends of the drying chamber, wherein a driving motor used for driving the rotating shaft to rotate is arranged on the outer side of the drying chamber; and paddles which are mounted on the rotating shaft. The drying machine has a self-cleaning capability, so that the wall sticking phenomenon is avoided; The safe operation of the system is ensured by high-degree inerting circulation; and the drying machine is high in heat exchange efficiency, high in heat transfer speed and high in sludge drying speed. When the drying system is used, irritant gas cannot be discharged to the periphery, and secondary pollution to air is avoided.

Description

technical field [0001] The invention relates to the technical field of wet sludge drying, in particular to a cyclone thermal vibration drying machine and a cyclone thermal vibration drying system. Background technique [0002] With the expansion of my country's industrial scale and the acceleration of urbanization, the output and treatment of sludge have increased year by year. my country's sludge is mainly composed of municipal sludge and industrial sludge. According to the statistics of the Ministry of Environmental Protection of China, the output of municipal sludge in my country in 2018 was 30 million tons, and the output of industrial sludge has exceeded 10 million tons. Calculated with a growth rate of 11.49%, the total sludge output will exceed 100 million tons in 2024. As a product of sewage treatment, sludge contains a large number of harmful substances such as bacteria, viruses, and microbial eggs. Without effective treatment and disposal, sludge can easily pollute...
