Drying device capable of recycling exhaust waste heat and dust of boiler

Abstract

A drying device capable of recycling exhaust waste heat and dust of a boiler is composed of a gas inlet pipeline, a first circulating pipeline, exhaust gathering and dust collecting pipelines, a plurality of cooling pipelines, pipeline valves, gas blow-by pipelines, exhaust buffering pipelines, a second circulating pipeline and an exhausting pipeline. The cooling pipelines are identical in volume and length, and the intervals between the cooling pipelines are identical. The cooling pipelines are arranged at the upper ends of the exhaust gathering and dust collecting pipelines, so that hot air rises and circulates, dust is prevented from gathering and causing blockage, and it is guaranteed that cooling is uniform; and in this way, the exhaust of the boiler is effectively utilized, and the gathering time of the exhaust of the boiler is prolonged. The comprehensive exhaust gathering caliber of the exhaust gathering and dust collecting pipeline is two times as large as the caliber of the first circulating pipeline and the caliber of the second circulating pipeline, the comprehensive exhaust gathering caliber of the cooling pipelines is 1.5-2 times larger than the caliber of the exhaust gathering and dust collecting pipeline, and therefore effective heat energy can be fully gathered on the cooling pipes. The drying device capable of recycling the exhaust waste heat and the dust of the boiler can effectively recycle the exhaust heat of the boiler and achieve the purposes of energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the field of environmental protection and heating equipment, and in particular relates to a drying device capable of recovering boiler tail gas waste heat and dust. [0002] technical background [0003] A boiler is a mechanical device that uses heat from fuel or other energy sources to heat water into hot water or steam. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power plant, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in ...
