Abstract
The utility model relates to a kind of residual heat from boiler fume recycling EGR.During current coal used for station boiler, moist coal sends into burner hearth, and burn incompletely can produce the gas such as carbon monoxide and nitric oxide, and these gas leaks can pollute the power station working environment easy serious consequence such as initiation personnel intoxication accident simultaneously.The utility model composition comprises: boiler smoke pipeline (1), boiler smoke pipeline is connected with smoke-intake pipe (2) and smoke exhaust pipe (3), smoke-intake pipe and smoke exhaust pipe are equipped with gas fume valve (4), smoke-intake pipe is connected with water heat medium device (5) one end, spillplate (6) is housed above water heat medium device, adjutage (7) and water inlet pipe (8) are housed below, water inlet pipe is connected with water pump (9), water pump is connected with water tank (11) by tube connector (10), the water heat medium device other end is connected with fume treatment pipeline (13) by putting smoke pipe (12), fume treatment pipeline is connected with smoke exhaust pipe.The utility model is applied to fume afterheat and utilizes.
Description
technical field:
the utility model relates to a kind of residual heat from boiler fume recycling EGR.
background technology:
during current coal used for station boiler, moist coal sends into burner hearth, and burn incompletely can produce the gas such as carbon monoxide and nitric oxide, and these gas leaks can pollute the power station working environment easy serious consequence such as initiation personnel intoxication accident simultaneously.
summary of the invention:
the purpose of this utility model is to provide a kind of residual heat from boiler fume recycling EGR.
above-mentioned object is realized by following technical scheme:
a kind of residual heat from boiler fume recycling EGR, its composition comprises: boiler smoke pipeline, described boiler smoke pipeline is connected with smoke-intake pipe and smoke exhaust pipe, described smoke-intake pipe and described smoke exhaust pipe are equipped with gas fume valve, described smoke-intake pipe is connected with water heat medium device one end, above described water heat medium device, spillplate is housed, adjutage and water inlet pipe are housed below, described water inlet pipe is connected with water pump, described water pump is connected with water tank by tube connector, the described water heat medium device other end is connected with fume treatment pipeline by putting smoke pipe, described fume treatment pipeline is connected with described smoke exhaust pipe.
described residual heat from boiler fume recycling EGR, described water heat medium device is hollow devices, and bottom is provided with snakelike hollow tube, and described snakelike hollow tube is provided with dewatering orifice, described dewatering orifice is connected with described adjutage, fills water in described water heat medium device hollow space.
the beneficial effects of the utility model:
1. boiler smoke pipeline is connected with water heat medium device by the utility model, the gas fume valve on smoke exhaust pipe is closed during use, open the gas fume valve on smoke-intake pipe, boiler smoke is made to enter the snakelike hollow tube of water heat medium device, water heat medium device hollow space fills water by water pump, and flue gas is in snakelike hollow tube during migration, and the heat of flue gas is absorbed by the water of hollow space, the coolant-temperature gage of water heat medium device hollow space is raised, thus to the coal heating, drying without oven dry be laid on water heat medium device; After oven dry terminates, by adjutage, the hot water in water heat medium device is discarded to the place recycling needing to use hot water.
the utility model is dried by the fire coal of fume afterheat to humidity, decrease carbon monoxide and the gas such as nitric oxide that coal-fired burn incompletely produces, improve the occurrence frequency that boiler surrounding working environment reduces personnel's intoxication accident simultaneously, the hot water after heating can also continue to utilize.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is upward views of accompanying drawing 1.
