Heat-exchange device 4 is included, heat-exchange device 4 is connect with the waste gas outlet of bringing-up section 11, and heat-exchange device 4 includes heat-preservation exhaust pipe 41
With heat-transfer pipe 42, heat-transfer pipe 42 is arranged in heat-preservation exhaust pipe 41, and heat-preservation exhaust pipe 41 is connected to waste gas outlet, heat-transfer pipe 42
One end is connect by connecting tube 3 with gas supply device 2, the other end of heat-transfer pipe 42 by connecting tube 3 and bringing-up section 11 into
Gas port connects.
The utility model is simple in structure, kiln body 1 is divided into bringing-up section 11 and cooling section 12, while setting in bringing-up section 11
Heat-exchange device 4 is set, gas supply device 2 supplies protective gas to kiln body 1, and the protective gas into bringing-up section 11 passes through
When heat-exchange device 4, make the high-temp waste gas that the waste gas outlet of bringing-up section 11 is discharged pass through heat-exchange device 4 transfer heat into
The protective gas for entering bringing-up section 11 makes protective gas temperature increase, reduces the heat that protective gas is absorbed in bringing-up section 11, drops
The low energy loss of bringing-up section 11, and the waste heat of equipment discharge is reduced, the pollution to environment is reduced, meanwhile, cooling section 12
As usual it is passed through the protective gas of low-temperature condition, cooperates with the carry out for the product processed to kiln cold with the cooling device of cooling section 12
But, cooling efficiency is improved, the energy consumption of kiln production is further reduced.
In the present embodiment, connecting tube 3 passes sequentially through the first control valve 5 and suspended body flowmeter 6 and bringing-up section 11 and cooling
The air inlet connection of section 12 needs protective gas to be protected since the time that different products heats in kiln is different
Region can according to different product different froms, at this time by the first control valve 5 carry out control different zones be passed through protection gas
The amount of body, plays energy saving, improves the effect of energy utilization rate, meanwhile, suspended body flowmeter 6 to be passed through the amount of protective gas into
Row calculates, and has further quantified the control for being passed through gas flow, convenient for the intake of control protective gas.

Qualitative, the protective gas being passed through reduces its speed being passed through by pressure reducing valve 23, makes full use of resource, protective gas is prevented to be lost in
It is too fast, finally, reinforce the control of protective gas intake by gas flowmeter 24, rationally utilizes protective gas.
In the present embodiment, heat-preservation exhaust pipe 41 and heat-transfer pipe 42 are co-axially mounted, and make heat-transfer pipe 42 in heat-preservation exhaust pipe 41
It is interior it is heated evenly while improving the rate of transform of high-temp waste gas heat, the caliber ratio of heat-preservation exhaust pipe 41 and heat-transfer pipe 42 is
(1~1.2):(5~5.3), make to be passed through the amount of protective gas and amount that high-temp waste gas is discharged is more reasonable, improve high-temp waste gas heat
Utilization rate.
Optionally, in the present embodiment, protective gas selects nitrogen, at this point, when nitrogen is using being 100M3/HR, by nitrogen
It is pre-heated to about 75 degree from 10 degree, needs about 46534277.1 joules of (J)=12.9261881 kilowatt hours (kWh) of absorbing heat；
Calculating formula is as follows：
According to The Ideal-Gas Equation PV=nRT, n=PV/RT=0.6 × 10^6* × 100/ (8.314 × 293) meter
It is 24630.5mol to calculate 100 cubes.In the heat for calculating heating and needing, due to the expansion of not no volume, so heating is all
For heating up, with t=1.0380741 × 24630.5 × 28 formula Q=Cm △ × (75-10)=46534277.1J, wherein
C is specific heat capacity.
It can be seen from the above, when selecting nitrogen as protective gas, in conjunction with the utility model, by 100 cubes of nitrogen from
10 degree are pre-heated to 75 degree, need the heat for consuming 46534277.1 joules (J), it can be seen that, the utility model is useless in high temperature
On the Btu utilization of gas, on the one hand, while saving a large amount of energy, reduce the discharge of waste heat, reduce the heat to environment
Pollution, on the other hand, the chemical property of nitrogen is relatively stable, and nitrogen content in air is higher, and acquisition difficulty is relatively low, into one
Step reduces the cost of processing.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
The scope of protection of the utility model is also should be regarded as into replacement.
