Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing and have
The utility model is described in further detail for body embodiment.
Fig. 1-3 is please referred to, Fig. 1 is provided a kind of structure of specific embodiment of residual neat recovering system by the utility model
Schematic diagram, Fig. 2 are provided the structural schematic diagram of another specific embodiment of residual neat recovering system, Fig. 3 by the utility model
The structural schematic diagram of another specific embodiment of residual neat recovering system is provided by the utility model.
As shown in Figure 1-3, the utility model provides a kind of residual neat recovering system, including generating set 1 and lithium bromide chiller
2, generating set 1, lithium bromide chiller 2 can utilize waste heat source 3.
Specifically, in two season of summer in winter, that is, there are season (or the special scenes, such as cold of refrigeration or heating needs
Zang Ku, publilc baths etc.), can preferentially start lithium bromide chiller 2, to meet refrigeration, the heating needs of user, waste heat source 3 still
It can star generating set 1 when having residue, more thoroughly to utilize the energy of waste heat source 3, can largely avoid energy
Waste；And in the season for not needing to freeze or heat, then 3 concentrated supply of waste heat source to generating set 1 can be generated electricity,
This part electricity can access alternating current, managed concentratedly, can also be supplied separately to particular device, to meet the use of user by country
Electricity demanding, at this point, if waste heat source 3 still not enough thoroughly, can be passed through lithium bromide chiller 2 again and made by the utilization of waste heat source 3
Cold or heating, to meet the refrigeration under specific environment, heating needs.
In other words, to waste heat source 3 when the provided residual neat recovering system of the utility model can overcome independent generating set 1
The problem of not used using transition seasons such as spring and autumn when halfway problem and independent lithium bromide chiller 2, can greatly improve
The utilization efficiency of waste heat source 3, can be more thorough to the utilization of waste heat source 3, can preferably meet user to hot and cold, electric
Demand.
In the scheme of Fig. 1, generating set 1 can connect with lithium bromide chiller 2, and waste heat source 3 can successively be passed through power generation
Unit 1, lithium bromide chiller 2.In the utility model embodiment, waste heat source 3 is specifically as follows boiler factory, steel plant, power plant, coke
The combination of one or more of the waste heats waste heat such as flue gas caused by Hua Changdeng factory, steam, hot water, exquisite diesel oil, is being arranged
At the beginning of putting, temperature with higher, such as flue gas caused by boiler factory, temperature is usually at 130 DEG C or more.
In use, the relatively high waste heat source 3 of this grade is preferentially passed through generating set 1, generating set 1 can be improved
Generating efficiency, and lithium bromide chiller 2 itself can efficiently utilize low-grade heat source, even if more than after generating set 1
The temperature of heat source 3 reduces, and can still guarantee higher utilization efficiency, more thoroughly to be utilized to waste heat source 3.
By taking waste heat source 3 is 110 DEG C of spent hot water as an example, after by generating set 1, temperature can be substantially reduced to
95 DEG C or so (value is not only related with the efficiency of generating set 1, in fact, it is also contemplated that the efficiency of subsequent lithium bromide chiller 2,
It is only for examples), after by lithium bromide chiller 2, temperature can be reduced to 55 DEG C or so (value and lithium bromide chillers 2
Efficiency it is related, the discharge temperature of different units also difference, it is only for examples).
In the arrangement in fig. 2, generating set 1 can be in parallel with lithium bromide chiller 2, and waste heat source 3 can each lead into power generation
Unit 1, lithium bromide chiller 2, since temperature of the waste heat source 3 at the beginning of discharge is higher, so that generating set 1, lithium bromide chiller 2 are equal
It can keep higher efficiency.
Still by taking waste heat source 3 is 110 DEG C of spent hot water as an example, a part therein can be passed directly into generating set 1, the portion
Divide after generating set 1, temperature can be reduced to 70 DEG C or so (merely illustrative), and another part can be passed directly into bromination
Lithium unit 2, after lithium bromide chiller 2, temperature can be reduced to 55 DEG C or so (merely illustrative) for the part.
In the scheme of Fig. 3, generating set 1 and lithium bromide chiller 2 can use series-parallel scheme, i.e., implement in Fig. 2
In example on the basis of parallel connection, generating set 1 and lithium bromide chiller 2 can also be cascaded, self generating sets 1 are discharged remaining
Heat source 3 is other than can be with direct emission, additionally it is possible to be passed through lithium bromide chiller 2, be carried out further with the waste heat source 3 to this part
Ground utilizes.
Three kinds of above-mentioned schemes be based on the same inventive concept under concomitant regimen, in practical applications, art technology
Personnel can carry out selection use according to actual needs.
It is to be appreciated that the utility model embodiment does not limit the specific structure of generating set 1 and lithium bromide chiller 2,
Those skilled in the art are referred to generating set 1 in the prior art completely, the specific structure of lithium bromide chiller 2 arranges this
Residual neat recovering system provided by utility model.
In a kind of illustrative scheme, the generating set 1 can using ORC (Organic Rankine Cycle, i.e.,
Organic Rankine Cycle) cogeneration unit, the generating set 1 of this form is for more low-grade heat source (200 DEG C or less) energy
Enough preferably utilized.In addition to this, which can also use external-combustion engine thermomotor circulating generation unit, surpass and face
Other cogeneration units in the prior art such as boundary's carbon dioxide recycle generating set.
Lithium bromide chiller 2 may include lithium bromide heat pump and/or lithium bromide refrigerator, wherein lithium bromide heat pump can be used
In heating, lithium bromide refrigerator can be used for freezing.It is to be understood that lithium bromide heat pump, lithium bromide refrigerator are actually same
Equipment is covered, difference essentially consists in the difference at output position, and therefore, the utility model embodiment can only provide a set of lithium bromide
Unit 2, the unit can have refrigeration mode and heating mode, to realize the function of refrigeration and heating respectively, it is of course also possible to
Two sets of units are set, to be respectively used to freeze and heat.
It further, can also include cooling tower 4, which can phase with generating set 1, lithium bromide chiller 2
Even, to realize between cooling tower 4 and generating set 1, between cooling tower 4 and lithium bromide chiller 2 cooling water circulation.Cooling tower 4
Structure be referred to the prior art, it is not described here in detail.
, it is emphasized that although the provided residual neat recovering system of the utility model is provided simultaneously with generating set 1 and lithium bromide machine
