Abstract

The utility model provides a fuel gas waste heat recovery device which comprises a fuel gas conveying pipe, a waste heat recoverer and a fuel gas exhaust pipe. The waste heat recoverer is arranged between the fuel gas conveying pipe and the fuel gas exhaust pipe; a cold water inlet pipe is disposed at the upper end of the waste heat recoverer and extends into the waste heat recoverer, and the lower end of the waste heat recoverer is provided with a hot water outlet pipe. By means of the technical scheme, the fuel gas waste heat recoverer is arranged in the fuel gas conveying pipe, fuel gas waste heat is used for converting cold water into hot water for reuse , and accordingly the aims of energy recovery and environment protection can be achieved.

Description

A kind of flue gas waste heat recovery apparatus
Technical field
The utility model relates to energy-saving and emission-reduction field, is specifically related to a kind of flue gas waste heat recovery apparatus.
Background technology
At present, the smoke evacuation in existing boiler or power plant is all often directly to airborne release, not only atmosphere is produced to greenhouse effects, and in vain the hot gas of its high temperature is bled off, and has wasted the energy.
Utility model content
The purpose of this utility model is to provide one rationally to utilize fume afterheat, reduces the hear rate of whole electro-heat equipment and the discharge of pollutant, improves efficiency of energy utilization, realizes energy-saving and cost-reducing flue gas waste heat recovery apparatus.
The technical solution of the utility model is achieved in that
A kind of flue gas waste heat recovery apparatus, comprises defeated smoke pipe, waste-heat recoverer and smoke exhaust pipe, and described waste-heat recoverer is located between described defeated smoke pipe and described smoke exhaust pipe; Described waste-heat recoverer upper end is provided with cold water inlet, and described cold water inlet extend into waste-heat recoverer inside, and the lower end of described waste-heat recoverer is provided with hot water outlet pipe.
Further, for making high-temperature flue gas that defeated smoke pipe can more be passed through, between described defeated smoke pipe and described waste-heat recoverer, be provided with air-introduced machine.
Further, for ease of hot water storage the sustainable heat recovery of carrying out, described hot water outlet pipe is connected with heat preservation hot water tank by pipeline.
Use technical solutions of the utility model, because flue gas waste heat recoverer is mounted in defeated smoke pipe, and utilize the waste heat of flue gas that cold water is changed into hot water recycling, therefore can reach, energy reclaims and the object of environmental protection.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
In the utility model embodiment, be recovered as example with residual heat from boiler fume, obviously technical solutions of the utility model are also applicable to the waste heat recovery in the soot combustion in power plant.See Fig. 1, a kind of flue gas waste heat recovery apparatus, comprises defeated smoke pipe 1, waste-heat recoverer 2 and smoke exhaust pipe 3 that boiler 10 connects, and waste-heat recoverer 2 is located between defeated smoke pipe 1 and smoke exhaust pipe 3; Waste-heat recoverer 2 upper ends are provided with cold water inlet 4, and cold water inlet 4 extend into waste-heat recoverer 2 inside, and the lower end of waste-heat recoverer 2 is provided with hot water outlet pipe 5.
For making high-temperature flue gas that defeated smoke pipe 1 and waste-heat recoverer 2 can be passed through more smoothly, in the utility model embodiment, between smoke exhaust pipe 3 and waste-heat recoverer 2, be preferably provided with air-introduced machine 6.
In the utility model embodiment, for ease of hot water storage the sustainable heat recovery of carrying out, hot water outlet pipe 5 is connected with heat preservation hot water tank 8 by pipeline 7.
Use technical solutions of the utility model, in defeated smoke pipe, waste-heat recoverer is installed, in waste-heat recoverer, be provided with cold water inlet and hot water outlet pipe, effectively utilized the waste heat of flue gas that cold water is changed into hot water recycling, reach the object of energy recovery and environmental protection.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
