All other embodiments, which can be made by one of ordinary skill in the art without the benefit of the present disclosure, are intended to be within the scope of the present application based on the described embodiments.

Referring to fig. 1, the present embodiment provides a ventilation and smoke exhaust system for an excitation room, which includes an excitation room 2 in a factory building 1, and a ventilation and smoke exhaust device for communicating the excitation room 2 with the outside of the factory building 1, wherein the ventilation and smoke exhaust device is located at the top of the excitation room 2.

The ventilation and smoke exhaust device discharges hot air in the exciting room to the outer side of the factory building 1 to cool the exciting room 2 through the temperature in the factory building 1, or alternatively, air outside the factory building 1 is conveyed into the exciting room 2 to cool the exciting room 2, and the temperature in the exciting room 2 can be generally selected according to the temperature in the inner environment and the outer environment of the factory building 1, namely, the temperature in the factory building 1 is lower than the temperature in the exciting room 2 and the temperature outside the factory building 1, then the air in the exciting room 2 is discharged to the outside of the factory building 1, so that low-temperature air in the factory building 1 enters the exciting room 2 to cool the exciting room 2; or when the temperature outside the factory building 1 is lower than the temperature inside the factory building 1 and the temperature of the exciting room 2, the low-temperature air outside the factory building 1 is selectively conveyed into the exciting room 2 to cool the exciting room 2, so that the stable and reliable operation of equipment inside the exciting room 2 is ensured.

Further described, the ventilation and smoke exhaust device comprises a first fan 3, a second fan 5 and a ventilation pipe 4, wherein the first fan 3 is arranged at the top of the excitation chamber 2, the second fan 5 is arranged on the side wall of the factory building 1, the second fan 5 is positioned above the excitation chamber 2, the first fan 3 is connected with the second fan 5 through the ventilation pipe 4, and the first fan 3 and the second fan 5 realize that smoke in the excitation chamber 2 is conveyed to the outside of the factory building 1 or low-temperature air outside the factory building 1 is conveyed into the excitation chamber 2 through positive and negative rotation control.

It is further preferred that a third fan 7 is installed on a side wall of the excitation chamber 2 so that fresh air in the factory building 1 can be replenished to the excitation chamber 2 through the third fan 7 when the inside of the excitation chamber 2 is exhausted or exhausted.

In order to reduce the limitation of manual control, a temperature sensor and a smoke sensor can be selectively arranged in the exciting chamber 2, by simultaneously connecting the first fan 3 and/or the second fan 5 with the temperature sensor and the smoke sensor, the first fan 3 and the second fan 5 are usually required to be in communication connection, so that the first fan 3 and the second fan 5 rotate in the same direction, in order to avoid damage to one fan and the other fan can not synchronously rotate, the temperature sensor and the smoke sensor can be respectively connected with the first fan 3 and the second fan 5, when the temperature in the exciting chamber 2 is higher, the temperature of the temperature sensor reaches a set value, the first fan 3 and the second fan 5 rotate, low-temperature air outside the factory building 1 is conveyed into the exciting chamber 2, when smoke exists in the exciting chamber 2, the smoke sensor is started, and simultaneously the first fan 3 and the second fan 5 rotate, and the smoke in the exciting chamber 2 is conveyed to the outside of the factory building 1 through the ventilation pipe 4; in order to avoid smoke generated in the exciting chamber 2 and at the same time when the temperature is high, the smoke sensor starts to control the corresponding rotation of the first fan 3 and the second fan 5.

In actual use, in order to avoid rainwater backflow caused by rain outside the plant 1, a rain shield is arranged outside the second fan 5, and the rain shield is arranged outside the plant 1 and connected with the outer wall of the plant 1; further, in order to reduce the emission of dust in the exciting chamber 2 into the atmosphere or to input external dust into the exciting chamber 2, a dust screen is optionally installed in the rain shield to ensure the cleanliness of the internal environment of the exciting chamber 2, and meanwhile, green emission is realized.
