The beneficial effects of the utility model, novel structure, simple, easy to use, energy-efficient performance and the floor space of greatly having improved RTO system are little, in addition, greatly reduce VOCs treatment capital construction cost, improve system works efficiency, further reduced energy loss.
[accompanying drawing explanation]
Fig. 1 is structural principle schematic diagram of the present utility model;
In figure: 1 for system fan, 2 is for lift valve A, 3 is for lift valve B, 4 is for energy storage bed A, 5 is for energy storage bed B, 6 is for burner hearth, 7 waste-heat ovens, 8 combustion fans, 9 damper A, 10 damper B, 11 are for combustion air air preheater, 12 mixes wind damper, 13 deep fats add hot air disperser.
[specific embodiment]
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, the structure of this device is very clearly concerning this professional people.
Air preheater as shown in Figure 1, original heat accumulation type exhaust-gas treatment equipment comprises burner hearth, described burner hearth inside is provided with the loop cycle being made up of some energy storage beds and inhales heat-releasing device, the outside corresponding every suit energy storage bed of described burner hearth, respectively by air intake branch and go out first port of export and the second entrance point that gas branch pipe connects some lift valves, the first entrance point of described some lift valves connects respectively the inlet manifold at production line blower fan place by some air intake branches, second port of export of described some lift valves is interconnected to chimney import by going out gas branch pipe.
In the Equipment Foundations of said structure, further improve;
First, by burner hearth 6 left side perforates, this one end, hole is connected to waste-heat oven 7 arrival ends, and waste-heat oven 7 ports of export connect first arrival end in combustion-supporting air preheater 11 left sides, and first port of export on described combustion-supporting air preheater 11 right sides is connected to chimney import by the first pipeline and forms the first gas circuit;
Secondly, the second arrival end of combustion-supporting air preheater 11 front sides is connected to combustion fan 8, another perforate end that second port of export of described combustion-supporting air preheater 11 rear sides is connected to burner hearth 6 rear sides by second pipe forms the second gas circuit.Make the first gas circuit and the second gas circuit be cruciform shape in combustion-supporting air preheater 11 places.
Finally, process adjusting device.Specifically, between combustion fan 8 and combustion-supporting air preheater 11 second arrival ends, be provided with damper A9; Combustion fan 8 is interconnected by an arm and second pipe, and described arm is provided with damper B10, and the temperature that the aperture of damper needs according to system is determined.The first pipeline is provided with and mixes wind damper 12, and second pipe is provided with deep fat and adds hot air disperser 13.Combustion air in described combustion fan 8 adopts hot-air or normal temperature air.
