Abstract

The invention discloses an industrial-boiler flue gas waste heat recycling device which comprises a base, an industrial boiler, a flue gas filter tank, a coal preheating tank and a soot collecting tank. The flue gas filter tank and the coal preheating tank are arranged between stand columns installed on the base separately, a second dust hood is fixedly installed on the lower portion of the flue gas filter tank, the upper portion of the second dust hood communicates with the lower portion of the flue gas filter tank, and the coal preheating tank is rotationally connected with the two stand columns through rolling bearings; and an exhaust pipeline is arranged under the coal preheating tank, the exhaust pipeline communicates with a suction pipeline through a negative pressure fan, the exhaust pipeline is located over the soot collecting tank, the coal preheating tank comprises an enclosing plate, a movable cover, side plates and a rotating rod, and multiple filter screens are fixedly installed in the flue gas filter tank from top to bottom in sequence. The industrial-boiler flue gas waste heat recycling device is simple in structure, reasonable in design, capable of effectively utilizing waste heat of flue gas in the boiler for drying and preheating coal and improving the burning efficiency of the coal and high in practicability.

Description

technical field [0001] The invention relates to the field of industrial boilers, in particular to an industrial boiler flue gas waste heat recovery and utilization device. Background technique [0002] There are two types of industrial boiler products. One is steam, which is used for power generation or gas supply. For example, chemical fertilizer plants can be vaporized with steam, and coal is used as raw material to synthesize chemical fertilizers. This is a typical industrial boiler. Industrial boilers still use coal as the main component Most, gas-fired waste heat boilers are generally used to recover waste heat. The most common industrial boilers are circulating fluidized bed boilers. Industrial boilers are important thermal power equipment. my country is the country that produces and uses the most boilers in the world today. China's manufacturing industry was established and developed after the founding of New China. For a long period of time in the future, coal-fire...
