The embodiment of the invention provides an air cooling refrigerator and a defrosting control method thereof, and relates to the field of refrigerator control, wherein refrigerator defrosting can be achieved in a more labor-saving manner. The air cooling refrigerator comprises a freezing chamber and a cold storage chamber which achieve heat isolation through a heat insulation partition plate, an evaporator chamber used for providing the cooling capacity for the freezing chamber and the cold storage chamber, a freezing air flue and a cold storage air flue. The evaporator chamber is located in the freezing chamber and internally provided with an electric heater and a temperature sensor. The freezing air flue is used for transmitting the cooling capacity in the evaporator chamber to the freezing chamber, and the cold storage air flue is used for transmitting the cooling capacity in the evaporator chamber to the cold storage chamber. The evaporator chamber and the cold storage air flue are isolated or communicate with each other through a first air door. The freezing air flue and the evaporator chamber communicate with each other through a freezing air inlet, the storage space of the freezing chamber communicates with the evaporator chamber through a freezing air return port, and the freezing air inlet is provided with a second air door.

The invention relates to the technical field of boiler denitration, in particular to a device for improving the SNCR denitrification efficiency of a circulating fluidized bed boiler, comprising a feed bin, a circulating fluidized bed boiler furnace and a shaft flue, the lower end of the circulating fluidized bed boiler furnace and the feed bin Connection, the upper end of the circulating fluidized bed boiler furnace is connected to the separation and return mechanism, the upper and lower ends of the separation and return mechanism are respectively connected with the upper end of the shaft flue and the lower end of the circulating fluidized bed boiler furnace, and the lower end of the circulating fluidized bed boiler furnace is connected Oxygen supply mechanism, the upper end of the shaft flue is provided with a denitrification mechanism. This device for improving the SNCR denitrification efficiency of circulating fluidized bed boilers generates a changing magnetic field through an electromagnetic generator, so that NH 3 The charged ions or ion clusters that are ionized after the violent collision between the molecules and the NO molecules in the flue gas are under the action of the changing magnetic field force generated by the alternating current, which increases the probability of collision and the severity of the collision, making the reaction degree correspondingly increased and reduced. Chemical reaction activation energy, thereby improving the denitrification efficiency.
