Background
In the combustion process of the catalyst roasting furnace, in order to ensure that the roasting is more sufficient, oxygen-enriched oxygen supplementing gas needs to be introduced into the roasting furnace for assistance, however, the temperature difference between the oxygen supplementing gas and the roasting furnace is large, so the oxygen supplementing gas can enter the roasting furnace after being preheated.
At present, the tail gas of the flue gas of the catalyst roasting furnace is usually directly discharged into the atmosphere after reaching the standard, and the waste heat in the flue gas can not be fully recycled, so that a great amount of energy is wasted.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the defects of the prior art are overcome, the oxygen supplementing gas preheating device for the catalyst roasting furnace is provided, the waste heat of the flue gas can be fully recycled, and meanwhile, the oxygen-enriched gas can be efficiently supplemented into the roasting furnace.
The utility model discloses an adopt following technical scheme to realize:
catalyst bake burning furnace oxygenating gas preheating device over a slow fire, including baking burning furnace over a slow fire, bake burning furnace top and be equipped with the flue gas discharge pipe, be equipped with on the flue gas discharge pipe in proper order and preheat heat exchanger, cooling heat exchanger, denitrification facility and desulphurization unit, oxygenerator and air conduit all through draught fan, gaseous dehydrator with preheat the heat exchanger and bake burning furnace and be connected, the oxygenerator export is equipped with the oxygen suppliment control valve, is equipped with air control valve on the air conduit.
Preferably, a thermometer is arranged at an oxygen-enriched gas outlet of the preheating heat exchanger, so that the temperature of the oxygen-enriched gas after heat exchange can be displayed in real time.
Preferably, the preheating heat exchanger is also connected with the roasting furnace through a hot blast stove, and when the temperature of the oxygen-enriched gas after heat exchange of the flue gas does not meet the requirement, the oxygen-enriched gas enters the hot blast stove for further heating, and enters the roasting furnace after being fully preheated.
Preferably, the cooling heat exchanger is connected with a water inlet pipe and a water outlet pipe.
The working principle and the process are as follows:
after oxygen provided by an oxygen generating device is mixed with air, oxygen-enriched gas is sent to a gas dehydrator through an induced draft fan to remove water vapor in the gas, then enters a preheating heat exchanger to exchange heat with waste heat in flue gas, the oxygen-enriched gas is heated, the temperature is displayed through a thermometer, if the temperature requirement is met, the oxygen-enriched gas directly enters a roasting furnace, and if the temperature is insufficient, the oxygen-enriched gas enters a hot blast furnace to be continuously heated to the required temperature and then enters the roasting furnace; the flue gas enters the cooling heat exchanger after passing through the preheating heat exchanger to exchange heat with the heating medium, and is treated by the denitration device and the desulfurization device to be discharged after reaching the standard.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses can abundant recycle flue gas waste heat, avoid the waste of a large amount of heat energy, energy-concerving and environment-protective, can supply the oxygen-enriched gas in the efficient to the roaster simultaneously, improve the work efficiency who bakes the burning furnace over a slow fire.
