This high temperature combustible exhaust gas second-time burning retracting device also includes a heat exchanger, and the sealed tube between this air exhauster gas outlet and the drain tap is connected with the radiating tube of heat exchanger, and the air inlet pipe of this drying and setting machine is connected with the endothermic tube of this heat exchanger.
Beneficial effect, high temperature combustible exhaust gas second-time burning retracting device of the present utility model, the high-temperature gas that is mixed with combustible of discharging in the drying and setting machine is fed fully burning in the coal-burning boiler, not only removed and contained a large amount of combustibles in the waste gas that drying and setting machine discharges air is polluted, simultaneously can save the loss of coal-burning boiler, thereby reach good environmental protection and energy saving effect fire coal.
Relevant detailed content of the present utility model and technology are carried out very thin explanation with regard to the accompanying drawing that cooperates specific embodiment now.
Description of drawings
Fig. 1, the schematic diagram that gas circulation flowed when first kind of embodiment of the utility model worked;
Fig. 2, the schematic diagram that gas circulation flowed when second kind of embodiment of the utility model worked.
The specific embodiment
High temperature combustible exhaust gas second-time burning retracting device of the present utility model imports in the coal-burning boiler second-time burning and removes combustible by the combustible waste gas that has that drying and setting machine is discharged, and improves rate of energy when avoiding air polluted.
Please refer to shown in Figure 1ly, the high temperature combustible exhaust gas second-time burning retracting device of first kind of specific embodiment of the present utility model is made up of drying and setting machine 1, coal-burning boiler 2 and sealed tube.
In this first embodiment, the forming machine air inlet of this drying and setting machine 1 is tightly connected by sealed tube 10 and air blast 6, the gas outlet of this drying and setting machine 1 absorbs through exhaust gas recovery pipe 14, exhaust gas recovery pipe 14 passes through sealed tube 12 and is connected for coal-burning boiler 2, the high-temp waste gas that is mixed with combustible that drying and setting machine 1 is discharged directly is imported into and carries out second-time burning in the coal-burning boiler 2, the combustible that the removal meeting pollutes atmosphere, the high-temperature gas that does not contain combustible and fuel oil that produces is through air preheater 7 preheatings, through screen collector 9 dedustings, the clean gas that obtains is discharged atmosphere through chimney 8 again.
Flow swimmingly in above-mentioned sealing 12 pipes for ease of waste gas, this high temperature combustible exhaust gas second-time burning retracting device also includes an air exhauster 4, the air inlet of air exhauster 4 is connected with the exit seal of exhaust gas recovery pipe 14, one end of the outlet of air exhauster 4 and sealed tube 12 is tightly connected, the air inlet of sealed tube 12 other ends and air blast 3 is tightly connected, air blast 3 gas outlets are connected with the air inlet of coal-burning boiler 2, consider that this drying and setting machine 1 can also normally be worked when coal-burning boiler 2 is stopped using, the sealed tube 12 middle flow seal pipes 19 that also are provided with that connect this drying and setting machine 1 and coal-burning boiler 2, sealing pipe 19 is provided with air valve 16, when coal-burning boiler 2 cuts out, can open this air valve 16, after the waste gas of discharging in the drying and setting machine 1 directly enters air preheater 7 preheatings by sealed tube 19, remove flocking and oil through screen collector 9, enter in the atmosphere through chimney 8, reduce pollution atmosphere.
