Description
Technical field
The present invention relates to the appurtenances of Industry furnace, the work in particular by natural gas, liquefied gas etc. as fuel
Industry furnace impacts heat transfer unit (HTU) with heat accumulating type.
Background technique
Industrial furnace using natural gas, coal gas or fuel oil as fuel, its working principle is that heated work pieces to be added are placed
In burner hearth, heat temperature raising reaches the temperature of technique requirement, heat preservation or samming.During heating, generally believe that heat transfer has three
Kind form: radiation, convection current and conduction heating.
Cold stage at the beginning of heating, mainly by convective heat transfer, substantially without radiant heat transfer or radiant heat transfer effect
Very poor, the heat-exchange capacity that this stage is placed in burner hearth between heated work pieces to be added and furnace gas is poor, causes heating efficiency very low.
Convective heat transfer poor ability at the beginning of just because of heating, by taking Industrial Furnaces for Forging as an example, heating efficiency is very low, usually 10%
Within, certain or even only 3-5%, energy waste is serious；After heat storage type combustion, the thermal efficiency is improved to the left side 30-50%
The thermal efficiency has greatly improved in the right side, but has substantially achieved the heat-accumulating industrial furnace waste heat limit rate of recovery at this stage, then improve
Heating efficiency is difficult.
Temperature is higher when due to fuel combustion, and if Flame of Natural Gas reaches 2000 DEG C or more, the flame of such high-temperature is such as
Fruit is directly sprayed onto heated work pieces to be added, can burn out workpiece, and workpiece softening or partial melting etc. generate inside workpiece structure
Undesirable change influences performance and its related performance indicators even is greatly lowered, so being that flame must be avoided to be directly sprayed onto is to be added
The means that convective heat transfer is improved in heated work pieces, therefore in existing technology are few.Here it is the heating of cold stage convective heat transfer
The main reason for efficiency is very low.
Although high velocity burner can be used now, the flame of high velocity burner must avoid being directly sprayed onto be heated
It is general to get up using by work support to be heated far from flame on workpiece.For high temperature furnace, the side of parallel shafting is generallyd use
Formula, they all directly or indirectly reduce convective heat transfer effect, and convective heat-transfer coefficient is still very low, cause heating time longer, fire
Material consumes more etc..
How in the case where thermal-flame is not directly sprayed onto heated work pieces to be added, convective heat-transfer coefficient is improved, significantly
The heating efficiency of industrial furnace is improved, to shorten heating time, reduce fuel consumption, improve the uniform of temperature and gas in burner hearth
Degree is that the technical problem solved is urgently wanted in this field.
Summary of the invention
The present invention during heating, because convective heat-transfer coefficient is low, leads to heating efficiency for industrial furnace in the prior art
It is lower, extend heating time, increase the deficiencies of fuel consumption, provide and a kind of increase substantially the used for industrial furnace of heating efficiency
Heat accumulating type impacts heat transfer unit (HTU).

When heated work pieces to be added in burner hearth 31 and burner hearth 31, gas treatment equipment 1 is opened, and adjust the control valve on pipeline, by furnace
The flue gas of higher temperature in thorax 31 is from 11 discharge of the second opening, by the second heat storage 10, into the pumping of gas treatment equipment 1
Air pipe 2, after 1 pressurized treatments of gas treatment equipment, the high-speed gas being discharged from blowing pipe 3 is in blowing pipe 3, through the
One heat storage 8 enters burner hearth 31 from the first 9 high speeds of opening, forms high-speed impact convective heat transfer, high-speed flow is directly sprayed onto furnace
In heated work pieces to be added in thorax 31, convective heat transfer efficiency is improved；The control valve on pipeline is adjusted, gas phase answers reverse flow, furnace
The flue gas of higher temperature in thorax 31 is from first opening the 9, first heat storage 8 discharge, into the exhaust pipe of gas treatment equipment 1
2, after 1 pressurized treatments of gas treatment equipment, the high-speed gas being discharged from blowing pipe 3 is in blowing pipe 3, through the second accumulation of heat
Body 10 enters burner hearth 31 from the second 11 high speeds of opening, forms high-speed impact convective heat transfer, high-speed flow is directly sprayed onto burner hearth 31
In interior heated work pieces to be added, convective heat transfer efficiency is improved.During industrial 1 combustion heating of furnace body, the first heat storage 8 and
Pipeline where two heat storage 10, respectively alternately as air inlet, gas exhaust piping, the first opening 9 and the second opening 11 respectively as
The flue gas air inlet of burner hearth 31 is vented out, and high-temperature flue gas carries out heat exchange, regenerator temperature height by the heat storage on the pipeline
And accumulation of heat (while reducing the temperature of flue gas, flue-gas temperature is most as low as 100 DEG C or so), another one mouth will be through gas treatments
Gas after 1 pressurized treatments of device is heated after through the heat storage on the pipeline, and the raised flue gas of temperature is through this mouthful of high speed
Into burner hearth 31, high-speed impact convective heat transfer is formed；Under the control action of control valve, the first heat storage 8 and the second accumulation of heat
Pipeline where body 10, respectively alternately as air inlet, gas exhaust piping, air inlet and exhaust in turn forms flow of flue gas in burner hearth 31
Circulation canal.
The present invention, by the pipeline where the first heat storage 8 and the second heat storage 10, the first heat storage 8 and the second accumulation of heat
Body 10 is used as medium, and two heat storages absorb heat in turn and heat release, and one absorbs the heat storage for the high-temperature flue gas being discharged from burner hearth 31
There are so that gas temperature is lowered into pressurized treatments in gas treatment equipment 1；From 1 pressurization place of gas treatment equipment
Flue gas after reason, when flowing through second heat storage (heat storage is in the condition of high temperature at this time), reheating flue gas, formation high temperature,
In the gas injection to burner hearth 31 of high flow rate (high pressure), acts directly in heated work pieces to be added, significantly improve convective heat-transfer coefficient；
Especially during being increased to high temperature from low temperature, heat accumulating type impact heat transfer is formed, improves many times of convective heat-transfer coefficient, significantly
Improve heating efficiency；Experiments verify that heating efficiency of the invention, on the basis of traditional heat-accumulation combustion furnace, at least can again by
Heating efficiency raising 20%, it is even higher.
First heat storage 8 and the second heat storage 10 of the invention, is arranged in pairs, inside there is channel and heat for gas to pass through
Exchange media can not be described further using the heat storage of heat-accumulation combustion furnace in the prior art as the prior art herein.
According to actual needs, if industrial furnace is that more than one bleeding point and air blowing is arranged on multiple or same industrial furnaces
Mouthful, then multichannel first can be set on exhaust pipe 2 and blowing pipe 3 and be evacuated branch, the second pumping branch and the first air blowing
Branch and the second air blowing branch provide flue gas to multiple industrial furnaces simultaneously with the present apparatus, or pass through one to same industrial furnace
A above bleeding point and the pumping of inflatable mouth multichannel and air blowing, form the circulation path of flue gas, are respectively recycled.
