Abstract
The utility model relates to a heating furnace residual heat from flue gas heating system, gas gas heater (4) on setting up flue (3) between heating furnace (1) and chimney (2), be equipped with between the water inlet of the water inlet of gas gas heater (4) and the delivery port of expansion tank (5) continuous just gas gas heater (4) and the delivery port of expansion tank (5) booster pump (6), the delivery port of gas gas heater (4) and the water inlet of surge tank (7) are continuous and delivery ports surge tank (7) are continuous with the water inlet of heating user radiator (8), the delivery port of radiator (8) links to each other with the water inlet of expansion tank (5). This heating furnace residual heat from flue gas heating system can carry out secondary recycle to the emission flue gas of heating furnace, practiced thrift the energy promptly, has reduced the destruction to the surrounding environment again.
Description
Technical field
This utility model belongs to technical field of environment protection equipment, relates to a kind of heating installation, especially relates to
And one waste heat of flue gas of heating furnace reclaims heating installation.
Background technology
In the heating furnace that steel pipe's production enterprise uses, great majority are all to be produced by burning blast furnace gas
Heat amount, is used for heating steel billet.The high-temperature flue gas that heating furnace produces only passes through tentatively often
(such as air preheater) is utilized just directly idle discharge to be put, exhaust temperature still up to four or five hundred degree.
Such that cause the waste of the energy, again surrounding enviroment are caused certain impact.
For this reason, it may be necessary to waste heat of flue gas of heating furnace is recycled.But, there is presently no
It is specifically designed to the device that waste heat of flue gas of heating furnace recycles.Even if it addition, having for heating furnace
The device of flue gas heat recovery, its organic efficiency also ratio is relatively low, and recovery system is unstable,
It is difficult to meet the requirement that heats normally.
In view of the above-mentioned technological deficiency of prior art, in the urgent need to developing a kind of novel heating furnace
Flue gas heat recovery device.
Summary of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, it is provided that Yi Zhongjia
Heating furnace flue afterheat recovering heating device, it can utilize waste heat of flue gas of heating furnace to heat,
I.e. save the energy, be avoided that again the impact on surrounding.
To achieve these goals, the following technical scheme of this utility model offer: a kind of heating furnace
Flue gas waste heat recovery heating installation, it includes on the flue that is arranged between heating furnace and chimney
Flue gas heat-exchange unit, is characterized in that, the water inlet of described flue gas heat-exchange unit and the water outlet of expansion tank
Mouth is connected and sets between water inlet and the outlet of described expansion tank of described flue gas heat-exchange unit
Being equipped with booster pump, the outlet of described flue gas heat-exchange unit is connected and described with the water inlet of vacuum tank
The outlet of vacuum tank is connected with the water inlet of the radiator of heating user, going out of described radiator
The mouth of a river is connected with the water inlet of described expansion tank.
Further, wherein, described waste heat of flue gas of heating furnace recovery heating installation farther includes
The water replanishing device being connected with described expansion tank.
Waste heat of flue gas of heating furnace of the present utility model reclaims heating installation and has following Advantageous
Effect:
1, it can utilize waste heat of flue gas of heating furnace to heat, and has i.e. saved the energy, again can
Avoid the high-temperature flue gas impact on surrounding.
2, its heating water route is stable, it is possible to meet normal heating demands.
3, its simple in construction, low cost, it is simple to popularization and application.
Accompanying drawing explanation
Fig. 1 is the composition signal that waste heat of flue gas of heating furnace of the present utility model reclaims heating installation
Figure.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings, the content of embodiment
Not as the restriction to protection domain of the present utility model.
Fig. 1 shows that the composition of waste heat of flue gas of heating furnace of the present utility model recovery heating installation shows
It is intended to.Include as it is shown in figure 1, waste heat of flue gas of heating furnace of the present utility model reclaims heating installation
It is arranged on the flue gas heat-exchange unit 4 on the flue 3 between heating furnace 1 and chimney 2.Described flue gas heat exchange
The existence of device 4 makes the high-temperature flue gas of described heating furnace 1 directly can not be carried by described flue 3
To described chimney 2.But, the high-temperature flue gas of described heating furnace 1 to be introduced into described flue gas heat exchange
Device 4, is carried out with the cold water entered in described flue gas heat-exchange unit 4 in described flue gas heat-exchange unit 4
Discharged by described chimney 2 again after heat exchange.
The water inlet of described flue gas heat-exchange unit 4 is connected with the outlet of expansion tank 5 and described cigarette
It is provided with booster pump 6 between water inlet and the outlet of described expansion tank 5 of gas heat exchanger 4.
So, under the effect of described booster pump 6, it is possible to by the Cold water supply in described expansion tank 5
In described flue gas heat-exchange unit 4, and in described flue gas heat-exchange unit 4 with the height of described heating furnace 1
Wet body carries out heat exchange, thus cool water heating becomes hot water, and reduces described high-temperature gas
Temperature, i.e. achieves the recycling of the energy, turn avoid the high-temperature gas shadow to surrounding
Ring.
The outlet of described flue gas heat-exchange unit 4 is connected with the water inlet of vacuum tank 7 and described voltage stabilizing
The outlet of tank 7 is connected with the water inlet of the radiator 8 of heating user.So, after heat exchange
Hot water can enter in described vacuum tank 7 and enter described heat radiation after the voltage stabilizing of described vacuum tank 7
In device 8, described radiator 8 heat to user.Meanwhile, the existence of described vacuum tank 7,
It is stable for making the pressure supplying the hot water of described radiator 8, it is possible to ensure that acquisition is good
Heating effect.
The outlet of described radiator 8 is connected with the water inlet of described expansion tank 5.So, from
Water after the cooling out of described radiator 8 can be again introduced into described expansion tank 5, in order to water
Recycling, saving water resource.
Although the most not shown, but, in this utility model, it is preferable that described in add
Heating furnace flue afterheat recovering heating device farther includes the moisturizing being connected with described expansion tank 5
Device.So, when water tails off in cyclic process, can be carried out by described water replanishing device
Moisturizing, thus contribute to being normally carried out of heating.
The waste heat of flue gas of heating furnace of the present invention reclaims heating installation and can utilize more than flue gas of heating furnace
Heat heats, and has i.e. saved the energy, is avoided that again the high-temperature flue gas impact on surrounding.
Meanwhile, heating water route is stable, it is possible to meet normal heating demands.
Above-described embodiment of the present utility model is only to be made by clearly demonstrating this utility model
Citing, and be not the restriction to embodiment of the present utility model.For art
For those of ordinary skill, other multi-form can also be made on the basis of the above description
Change or variation.Here cannot all of embodiment be given exhaustive.Every belong to this practicality
Obvious change or variation that novel technical scheme is extended out are new still in this practicality
The row of the protection domain of type.
