The technical solution of the utility model realizes with following method.Drying room waste gases afterheat utilization device comprises drying chamber and for drying chamber provides the drying oven of heat, and the waste gas that it is characterized in that drying chamber goes out pipe and is connected with the waste gas burning stove, and the pipe of waste gas burning stove is connected with drying chamber.
The utility model can also connect heat exchanger A, and the pipe of drying chamber is open behind over-heat-exchanger A, blower fan and heat exchanger B.
The outlet pipe of above-mentioned heat exchanger B, through being connected with the water inlet pipe of hot-water boiler behind the water pump A, the outlet pipe of hot-water boiler is connected with the water inlet pipe of heat exchanger C behind the process water pump B, and the outlet pipe of heat exchanger C is connected with the water inlet pipe of hot-water boiler.
Another kind of mode of the present utility model is the outlet pipe of above-mentioned heat exchanger B, and through being connected with the water inlet pipe of heat exchanger C behind the water pump A, the outlet pipe of heat exchanger C is connected with the water inlet pipe of heat exchanger B.
Superior being in both having administered toxic emission of the present utility model reduced the pollution to atmosphere, can reclaim heat that burnt gas produces again and for the working region provides energy, economic environmental protection and considerable benefit.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is further described.Drying room waste gases afterheat utilization device comprises drying chamber 1 and for drying chamber provides the drying oven of heat, and its feature goes out pipe at the waste gas of drying chamber 1 and is connected with waste gas burning stove 2, and the pipe of waste gas burning stove 2 is connected with drying chamber 1.From drying chamber 1 interior waste gas of discharging, go out pipe by waste gas and be admitted in the waste gas burning stove 2, organic matter is in this decomposition combustion.The flue gas that waste gas burning stove 2 is discharged is at first delivered to drying chamber 1 heating region, and drying chamber is heated.The temperature of this flue gas is about 550 ℃.
Drying chamber is an example with 30m * 3.8m * 3.5m, and discharge amount of exhaust gas calculates according to theory.Empirical equation:
Q＝4G×K/t×a
Q---discharge amount of exhaust gas (M
3/ H)
G---be disposed to the solvent (g) in the drying chamber
K---safety coefficient 2.5
T---the solvent evaporates time (0.16H)
A---solvent LEL (48g/M
3)
Press 10 (coachbuilt body)/H of output, consumption lacquer amount is 3.5kg/ car (containing solvent 350g/ car) meter, the then about 4500M of capacity
3/ H gets 5000M
3/ H.Discharge amount of exhaust gas also can be by the 10-12 of drying chamber volume doubly.
The heat Calculation that flue gas discharges
The exhaust gas volumn of discharging is: 5000m
3/ h, temperature: 220 ℃, the heat that produces of flue gas then:
Q＝CM(T
2-T
1)
The heat that Q---flue gas discharges (kacl/h)
The specific heat (0 of C---gas.24kacl/m3。℃)
M---exhaust gas volumn (5000m
3/ h)
T
1——120℃
T
2——220℃
Q＝0。24×5000(220-120)＝120000(kacl/h)
This shows that the energy of its production is very considerable.
The utility model not only can be used for to drying chamber provides heat, and the energy consumption of heating can also be provided for the needed water of the paint line of vehicle.Promptly connect a heat exchanger 3, from the pipe of drying chamber, open behind over-heat-exchanger 3, blower fan 7 and heat exchanger 4.The i.e. flue gas that comes out from drying chamber 1 is a heat exchanger 3 through the fresh air preheater, and the flue gas that from then on comes out is admitted to through blower fan 7 and exchanges the back flue gas in the heat exchanger 4 and be discharged.The flue gas that comes out from drying chamber 1 is a heat exchanger 3 through the fresh air preheating chamber about 350 ℃ again, and the flue gas that goes out preheating chamber still has 200-220 ℃.Water in heat exchanger 4 grooves can be added to 90 ℃ by 70 ℃ like this.
The utility model also can be used for heating the needed water of this paint line pre-treatment with the heat that flue gas produced.Improved energy utilization ratio so greatly.The mode that is adopted is the outlet pipe LJ of above-mentioned heat exchanger 4, through being connected with the water inlet pipe of hot-water boiler 5 or the water inlet pipe of heat exchanger 6 behind the water pump 8A; The outlet pipe of hot-water boiler 5 is connected with the water inlet pipe of heat exchanger 6, and the outlet pipe of heat exchanger 6 is connected with the water inlet pipe of heat exchanger 4 or the water inlet pipe of hot-water boiler 5.The water that from heat exchanger 4 tanks, comes out thus, can through pump 8A deliver to hot-water boiler 5 or the work nest of the heat exchanger 6 handled of directly reaching the last in, in order to needed water in the pre-treatment of heating paint line.Press flue gas discharge rate 5000M
3/ H calculates, and recoverable energy 120,000 kilocalories/H can be saved natural gas (calorific value 8500 kilocalories/M
3) 14M
3/ H.Production capacity as vehicle body is 100,000/year, the fluid sealant of paint line then, in be coated with, finish paint three drying chamber length overalls have 150M.Be 5 times of above calculated value, can save natural gas 70M
3/ H, annual by 4200H, should save 294000M
