Abstract

The invention provides a rotary kiln barrel waste heat recovery system. The rotary kiln barrel waste heat recovery system comprises a rotary kiln barrel, a sleeve arranged on the rotary kiln barrel ina sleeving mode, an air supply device, an air suction device and a waste heat boiler. The sleeve is provided with an air inlet and an air outlet, and a clearance is arranged between the inner surfaceof the sleeve and the outer surface of the rotary kiln barrel. An air supply opening of the air supply device faces the air inlet. An air suction opening of the air suction device faces the air outlet. The waste heat boiler communicates with the air suction device. Thus, heat on the surface of the rotary kiln barrel can be centralized in the sleeve to be prevented from running off; due to the fact that airflow supplied by the air supply device can generate hot air of about 200 DEG C after passing through the surface of the rotary kiln barrel, and the hot air can be finally sucked back into the waste heat boiler to be utilized through the air suction device, so that the rotary kiln barrel waste heat recovery system has a high waste heat utilization rate.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a waste heat recovery system for a rotary kiln cylinder. Background technique [0002] Because the cement production process consumes a lot of energy in the production process of clinker formation and grinding, and there is a lot of energy waste in the cement production system, the cement plant has become a well-known energy-consuming household, and it will also generate a lot of energy. Exhaust gases containing thermal energy. At present, with the development of science and technology, the modern large-scale cement production process generally adopts a new dry production process of decomposition outside the kiln, which greatly improves the energy utilization rate. In order to generate electricity, the energy utilization rate is further improved. [0003] Existing waste heat recovery devices usually install heat exchange equipment on the surfa...
