Abstract

The utility model relates to a smoke waste heat exchanger for a boiler, which belongs to the technical field of a heat exchanging apparatus, and makes the smoke of the boiler have the effects of energy saving and environmental protection. The utility model has the technical scheme that the utility model comprises a smoke channel, and a water jacket which surrounds the smoke channel, wherein both ends of the smoke channel are provided with connecting flanges; a mounting hole of a manometer, a mounting hole of a safety valve and a pollution discharge hole are is arranged on the water jacket. The smoke channel and the water jacket surrounding the smoke channel are utilized to form a set of heat exchanging apparatus. After the heat exchanging apparatus is installed in a smoke discharging pipeline of the boiler, the waste heat of the smoke discharged by the boiler forms the heat exchange with the water; thus, the water in the water jacket of the heat exchanger can be heated for supplying the hot water for bathing, heating, etc. The utility model not only can greatly save lots of fuels but also has the dust removing function, so the utility model is favorable for environmental protection and can assist a dust remover to remove the dust. Thereby, the service life of the dust remover is prolonged.

Description

The residual heat from boiler fume heat exchanger

Technical field

The utility model relates to a kind of heat-exchanger rig that utilizes residual heat from boiler fume to carry out heat exchange, belongs to the heat-exchange apparatus technical field.

Background technology

In industry or civil boiler, the most widely used packaged boiler that surely belongs to medium and small tonnage, vertical or horizontal package boiler as the 1-5 ton.In use, to the pollution that surrounding environment causes, set up cleaner for preventing boiler smoke, even now still has flue dust and is discharged in the atmosphere more.These flue gases that are discharged can be taken away a large amount of waste heats, and this not only causes a large amount of energy wastes, also can cause to a certain degree pollution to the border environment.How making full use of boiler and discharge the waste heat in the flue gas and help environmental protection, is a problem that is worth research.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of energy-conservation and residual heat from boiler fume heat exchanger environmental protection of helping is provided.

It is as follows to address the above problem the technical scheme that is adopted:

A kind of residual heat from boiler fume heat exchanger, it comprises flue and around the water jacket of flue, the flue two ends are provided with adpting flange 1, and water jacket is provided with Pressure gauge installing hole 6, safety valve installing hole 7 and mudhole 13.

Above-mentioned residual heat from boiler fume heat exchanger is provided with the many heat exchange water pipes 12 that cross in the said flue 2, water pipe 12 two ends and walling of flue sealing and fixing, and water pipe 12 cavitys are communicated with water jacket 3-1.

Above-mentioned residual heat from boiler fume heat exchanger, said flue is made of the smoke box 15 of being located at water jacket 3-2 two ends and the vertical many smoke pipes 18 of wearing water jacket 3-2, smoke pipe 18 two ends and water jacket 3-2 end wall sealing and fixing, smoke pipe 18 cavitys are communicated with smoke box 15.

Above-mentioned residual heat from boiler fume heat exchanger is provided with bracing frame 17 between 18 of said many smoke pipes and smoke pipe 18 and water jacket 3-2 wall.

Above-mentioned residual heat from boiler fume heat exchanger, said water jacket 3-1,3-2 are provided with and clean charge door 8.

Above-mentioned residual heat from boiler fume heat exchanger, said water jacket 3-1,3-2 bottom are provided with bearing 11.

Above-mentioned residual heat from boiler fume heat exchanger, ash disposal mouth 16 is established in said smoke box 15 bottoms.

Above-mentioned residual heat from boiler fume heat exchanger, said water jacket is provided with thermometer installing hole 5.

The utility model utilizes flue and forms one group of heat-exchange apparatus around the water jacket of flue, after being installed in it in the boiler exhaust gas pipeline, the fume afterheat and the water that utilize boiler to discharge carry out heat exchange, with the heating of the water in the heat exchanger water jacket, are used to provide hot water such as bathing, heating.This is fuel savings in a large number not only, but also has the dedusting effect concurrently, both helped environmental protection, but the assisted dust-collecting device carries out the dedusting operation again, prolongs the service life of deduster.
