Compared with the prior art, the flue type waste heat recovery device has the beneficial effects that the flue is connected in segments, and each part is provided with an independent heat-exchange system, therefore, the integral structure is simple, the assembling is convenient, and the efficiency is high, thereby realizing different heating purposes; besides, the energy is saved, and the environment is protected.

Description

The chimney flue type waste heat recovery plant
Technical field
The utility model relates to a kind of waste heat recovery plant, belongs to resource reutilization equipment, refers in particular to a kind of chimney flue type waste heat recovery plant.
Background technology
In the modern society of industry high speed development, along with improving constantly of economic level and living standard, the application of power-equipment of all kinds (as internal combustion engine, boiler etc.) is more and more general, and industrial society and development of human society are had important role.But, these power-equipments in use can produce used heat to external world, and the used heat that gathers when external environment is when more and more, to have a strong impact on existent environment of people, cause the continuous rising of earth atmosphere temperature, particularly in the higher city of up-to-dateness, the influence that used heat caused is also more serious relatively.
So, people research and develop and have produced various waste heat recovery plants, the chimney flue type waste heat recovery plant is wherein a kind of, this retracting device uses the used heat that power-equipment produced as far as possible, thereby reduce used heat and directly be discharged into the external world, solve the pollution problem of waste heat discharge, reduce corresponding energy resource consumption, thereby reach the purpose of energy-conserving and environment-protective.But, existing chimney flue type waste heat recovery plant structure more complicated, and also flue is structure as a whole, and can't make corresponding adjustment at the variations in temperature in the waste heat discharge process, reaches different heating application targets.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of simple in structure, easy to assembly, efficient is high and the flue segmentation connects chimney flue type waste heat recovery plant is provided.
To achieve these goals, the utility model is realized by following technical scheme:
A kind of chimney flue type waste heat recovery plant comprises flue and heat-exchange system; Described flue comprises at least two flue unit that join and communicate, and each flue unit is provided with at least one heat-exchange system.
Further, described heat-exchange system comprises and the matching used heat exchanger in flue unit, and the external heat supply mechanism that is connected with heat exchanger.
Further, described heat exchanger is built in the flue unit.
Further, described heat exchanger is placed on the flue unit.
Further, the inside and outside flue unit that places of described heat exchanger.
Further, described external heat supply mechanism is band air pump heat supply mechanism, or band water pump heat supply mechanism.
The utility model compared with prior art, its beneficial effect is: the flue segmentation connects, and each part all has independently heat-exchange system, and overall structure is simple, and is easy to assembly quick, it is convenient to safeguard, and the efficient height, can realize different heating purposes, energy-conserving and environment-protective.
In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.

The specific embodiment
Embodiment 1
As shown in Figure 1, 2, chimney flue type waste heat recovery plant described in the utility model comprises flue 1 and heat-exchange system 2.
Above-mentioned flue 1 adopts the segmentation connected mode, comprises three flue unit 11 that communicate, and 11 of flue unit join in regular turn by adpting flange, and each flue unit 11 is equipped with an independently heat-exchange system 2.Flue 1 can be made according to the mode of original power-equipment discharge duct, specification etc., can replace original pipeline fully and does not influence the installation design of power-equipment.The assembling mode that segmentation connects, can utilize the characteristics of waste heat discharge, temperature is the segmentation heat-obtaining from high to low, the front end used heat temperature nearer as the distance exhaust outlet can reach about 500 ℃, can be used for heating the heat outputting steam, middle-end used heat temperature decreases, and can be used to heat boiling water, and terminal used heat temperature further reduces, and then can be used for heating provides general life hot water.
Above-mentioned heat-exchange system 2 comprises with flue unit 11 matching used heat exchangers 21, reaches the external heat supply mechanism (not drawing among the figure) that is connected with heat exchanger 21.Heat exchanger 21 is built in flue unit 11, directly contacts with used heat and carries out heat exchange; External heat supply mechanism adopts the heat supply mechanism of band water pump, utilize water pump to extract running water, carry out exchange heat, thereby reach the purpose of drawing the waste heat water source with heat exchanger, not only reduce the discharging of used heat, and can utilize used heat to reach the thermal effect that adds of domestic water.
Embodiment 2
Shown in Fig. 3,4, the described embodiment of present embodiment is substantially the same manner as Example 1, difference only is, the waste gas used heat of present embodiment medium power equipment exhausting has corrosivity, therefore heat exchanger 21 is placed on flue unit 11, thereby avoid heat exchanger 21 to be subjected to rust corrosion, all the other beneficial effects are identical with embodiment 1 with user's rule.
Embodiment 3
Shown in Fig. 5,6, the described embodiment of present embodiment and the foregoing description are basic identical, difference only is, heat-exchange system is provided with two heat exchangers 21 in the present embodiment, the inside and outside respectively flue unit 11 that places, so can further improve the heat exchange effect, further improve the efficiency of heating surface, all the other beneficial effects and user's rule are same as the previously described embodiments.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
