Abstract
The invention discloses a kind of industry kiln stove waste heat recovery system and exhaust heat recovering method, which includes residual neat recovering system unit, incubator, bath wastewater and waste heat tank.The beneficial effects of the invention are as follows：Industrial Stoves after the heating can remaining amount of heat, these heats are thrown away by waste in vain.And temperature when similarly waste heat recovery unit discharges again only has 35 degree, 35 subtract 5 degree this mean that 30 degree of thermal energy has been stayed in unit, it is introduced in unit 14 degree or so of heat, 14 degree are equal to 44 degree plus 30 degree, waste heat recovery unit operation cost only needs 4 degree of electricity, more than 75% electricity charge are saved than electrical heating, saving 50% than coal-fired, gas fired-boiler operates above cost.
Description
Technical field
The present invention relates to a kind of industry kiln stove waste heat recovery technology, specifically a kind of industry kiln stove waste heat recovery system and remaining
Heat recovery method belongs to industry kiln stove waste heat recovery technology field.
Background technology
Waste heat refers to the limitation by history, technology, theory etc., in the industrial consumption energy device to have put into operation, original design
The sensible heat and latent heat not being used appropriately, it includes high-temp waste gas waste heat, cooling medium waste heat, waste vapour waste water residual heat, high temperature production
Product and afterheat of slags, chemical reaction waste heat, combustible exhaust gas waste liquid and waste material waste heat etc..According to investigation, the waste heat of every profession and trade always provides
Source accounts for about the 17%~67% of its fuel consumption total amount, and the residual heat resources of recoverable are about the 60% of waste heat total resources.Work
Amateurish heat is by the use of from the waste heat that industrial equipment recycles as the Urban District Heating of heat source.Most energy consumption equipments, it is such as former
The sub-fraction in thermal energy is all only utilized in motivation, heating furnace etc..The industrial exhaust heat that a recycling part was passed into disuse originally carries out
Central heating can save primary energy, increase economic efficiency, and reduce pollution.
Existing industry kiln stove waste heat recovery technology is simultaneously not perfect, this allows for industry kiln stove waste heat recovering effect and is not achieved
Preferably, huge obstruction is brought for the progress of industry kiln stove waste heat recovery technology.
Invention content
In view of the problems of the existing technology, the present invention provides a kind of industry kiln stove waste heat recovery system, the industry kiln
Stove residual neat recovering system includes residual neat recovering system unit, incubator, bath wastewater and waste heat tank.
Preferably, Step 1: Step 2: step 3 and step 4.
Preferably, the step 1 is：By in waste heat centralized collection to waste heat tank, the size of waste heat tank is used according to heat
Flow or maximum use time heat determine.
Preferably, the step 2 is：The waste heat to be got off using pipeline is uniformly flowed into heat recovery system unit, is connect simultaneously
Enter other heats.
Preferably, the step 3 is：Heat exchange, the object contained in heat are proceeded by inside heat recovery system unit
Matter is without exchanging, and only temperature swaps.
Preferably, the step 4 is：Waste heat after thermal energy exchange enters from heat recovery system unit other end outflow waste heat
Residual neat recovering system unit can also carry out continuing moisturizing heating to it after incubator.
The beneficial effects of the invention are as follows：Industrial Stoves after the heating can remaining amount of heat, these heats are by wave in vain
Expense is thrown away.And temperature of same waste heat recovery unit when discharging again only has 3-5 degree, 35 subtract 5 degree this meant that 30 degree
Thermal energy stayed in unit, introduced in unit 14 degree or so of heat, 14 degree plus 30 degree equal to 44 degree, waste heat recovery
Unit operation cost only needs 4 degree of electricity, and more than 75% electricity charge are saved than electrical heating, saves more than 50% than coal-fired, gas fired-boiler and transports
Row cost.
Specific embodiment
The technical solution in the embodiment of the present invention will be clearly and completely described below.Obviously, described implementation
Example is only part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiments obtained without making creative work belong to the model that the present invention protects
It encloses.
A kind of industry kiln stove waste heat recovery system, industry kiln stove waste heat recovery system include residual neat recovering system unit, protect
Incubator, bath wastewater and waste heat tank.
Preferably, Step 1: Step 2: step 3 and step 4.
Preferably, step 1 is：By in waste heat centralized collection to waste heat tank, the size of waste heat tank uses flow according to heat
Or maximum use time heat determines.
Preferably, step 2 is：The waste heat to be got off using pipeline is uniformly flowed into heat recovery system unit, while accesses it
His heat.
Preferably, step 3 is：Heat exchange is proceeded by inside heat recovery system unit, the substance contained in heat is not
It swaps, only temperature swaps.
Preferably, step 4 is：Waste heat after thermal energy exchange enters heat preservation from heat recovery system unit other end outflow waste heat
Residual neat recovering system unit can also carry out continuing moisturizing heating to it after case.
Better embodiment of the embodiment provided above for the present invention only is used for facilitating illustrating the present invention, not to this hair
The limitation of bright work in any form, any those of ordinary skill in the art, if putting forward skill not departing from the present invention
In the range of art feature, using the equivalent embodiment for locally changing or modifying made by disclosed technology contents, and
Without departing from the technical feature content of the present invention, in the range of still falling within the technology of the present invention feature.
