[0022] Please refer to Figs. 1-3 The noise reduction system of one embodiment includes a shell with a cavity and a power device, which is used in connection with the tail gas system of sterilization raw materials, that is, the tail gas discharged by the tail gas system of sterilization raw materials passes through the noise reduction system before being discharged. The tail gas system of sterilization raw materials is the tail gas system after ethylene oxide sterilization. The power device is arranged in the cavity of the shell. In this embodiment, the shell is a rectangular parallelepiped. The shell has a first plate 110, that is, when the shell is a rectangular parallelepiped, the shell can be composed of six plates, and the six plates are connected in sequence to surround the cavity. One of the side plates is the first plate 110. A through hole 111 is formed in the first plate 110, and the through hole 111 is in communication with the air inlet of the power device, that is, the position of the through hole 111 is exactly the position of the air inlet of the power device. The air inlet of the power device is in communication with the first air outlet of the tail gas system, and the two can be communicated through a flexible air pipe. In this embodiment, the power device can be a fan.

[0023] The first plate comprises a first part 112, a second part 113 and a third part 114, which are detachably connected with each other, i.e. the first part 112 is detachably connected with the second part 113, the second part 113 is detachably connected with the third part 114, and the first part 112 is detachably connected with the third part 114, and the first part 112, the second part 113 and the third part 114 surround to form the through hole 111. Thus, when the air inlet of the power device needs to be maintained, the first part 112, the second part 113 and the third part 114 can be disassembled for maintenance.

[0024] The shell further has a second air outlet, and the gas discharged from the first air outlet of the exhaust system enters the through hole 111, passes through the power device and is discharged from the second air outlet. By arranging the power device in the cavity of the shell, the power device in the shell can reduce the noise generated during the operation of the power device. In an embodiment, the shell comprises a third plate 120, and the third plate 120 has a second air outlet. The third plate 120 can be opposite to the first plate 110, i.e. the first plate 110 and the third plate 120 are respectively two opposite sides of the shell. It should be noted that the second air outlet can be located near the top of the third plate 120.

[0025] In addition, the second air outlet can be provided with a first shielding cover 122, and the first shielding cover 122 is used for shielding the second air outlet and is in communication with the second air outlet. The first shielding cover 122 has an opening, and the axis of the opening is perpendicular to the axis of the second air outlet, i.e. the center axis of the opening is not on the same straight line as the center axis of the second air outlet, and the two are arranged at an angle. By adopting this arrangement, the flow direction of the exhaust gas discharged from the second air outlet can be changed, the flow speed of the exhaust gas can be slowed down, and the exhaust noise can be further reduced. Further, the inner side of the first shielding cover 122 can be provided with a noise reduction material layer to further reduce the noise.

[0026] In an embodiment, the second part 113 and the third part 114 are symmetrically distributed relative to the radial direction of the through hole 111, the first part 112 is symmetrically distributed relative to the axial direction of the through hole 111 with the whole formed by the second part 113 and the third part 114, and the first part 112, the second part 113 and the third part 114 are detachable from each other. In this way, the first plate is convenient to disassemble and install. Further, the first part 112 is connected with the second part 113 through buckling, the second part 113 is connected with the third part 114 through buckling, and the first part 112 is connected with the third part 114 through buckling. In this way, the first plate is convenient to disassemble and install. It should be noted that the first part 112, the second part 113 and the third part 114 can also be connected through a lock or the like. Since the volume of the shell is large, the volume of the first part 112, the second part 113 and the third part 114 is also large. After the buckling between the first part 112, the second part 113 and the third part 114 is disassembled, the intake port of the power device is further convenient to maintain. The first part 112, the second part 113 and the third part 114 can be arranged in a sliding manner. In other words, the first part 112 is arranged in a sliding manner relative to the top plate of the shell, that is, the top plate of the shell is provided with a sliding track, and the second part 113 and the third part 114 are arranged in a sliding manner relative to the bottom plate of the shell, and the bottom plate of the shell is provided with a sliding track. The first part 112, the second part 113 and the third part 114 can all adopt a foldable structure. For example, the first part 112, the second part 113 and the third part 114 can all be curtains. When the intake port of the power device needs to be maintained, the first part 112, the second part 113 and the third part 114 are slid to be folded. In this way, the structure is simple and convenient to operate. The first part 112, the second part 113 and the third part 114 can be made of cloth or plastic.

[0027] In an embodiment, the noise reduction system further comprises a temperature sensor and a cooling device, both of which are arranged in the shell, and the temperature sensor is electrically connected with the cooling device. Specifically, the temperature sensor can be arranged on the inner wall of the shell, and the cooling device is arranged in the cavity or mounted on the inner wall of the shell, and the cooling device can be an air conditioner or the like. The temperature sensor is used to detect the temperature in the shell, and when the temperature in the shell reaches a preset temperature, the cooling device is started to cool the cavity in the shell, so as to avoid the temperature of the gas discharged by the exhaust system being too high due to the temperature in the shell being too high. It should be noted that the noise reduction system can further comprise a control device connected with the temperature sensor and the cooling device, respectively. The temperature sensor sends the detected temperature in the shell to the control device, and the control device starts or stops the cooling device according to the received temperature. The control device can be a CPU or the like.

[0028] Further, the noise reduction system can further comprise a concentration detection sensor and an exhaust device, both of which are arranged in the shell, and the concentration detection sensor is electrically connected with the exhaust device. Specifically, the concentration detection sensor is arranged at the bottom of the cavity of the shell, and the concentration detection sensor is used to detect the concentration of the gas in the shell. If it is detected that the gas discharged by the exhaust system, the exhaust device is started to exhaust, so as to avoid the situation that the local concentration is too high due to the gas leakage, which leads to an unsafe situation. The concentration detection sensor is a gas detection sensor. The concentration detection sensor can be arranged at the through hole, that is, the concentration detection sensor is located near the through hole 111, that is, near the air inlet of the power device, so that if the gas discharged by the exhaust system leaks when entering the noise reduction system, it can be detected in time, and then the exhaust device is started to exhaust, thereby improving the safety. It should be noted that the number of concentration detection sensors can also be multiple, and the multiple concentration detection sensors are arranged in the shell at intervals. If any concentration detection sensor detects the gas discharged by the exhaust system, the exhaust device is started. Further, the concentration detection sensor can be directly electrically connected with the exhaust device, and the concentration detection sensor can also be connected with the control device, and the control device is connected with the exhaust device, that is, the concentration detection sensor sends the detected information to the control device, and the control device controls the start of the exhaust device. The exhaust device can be a fan.

[0029] Further, the noise reduction system can further comprise an alarm. When the concentration detection sensor detects the gas, it sends a signal to the alarm, and the alarm is started to work, thereby prompting and further improving the safety. The alarm can be a bell or a light emitting device, which can produce sound or light for warning.

[0030] In an embodiment, a second shielding cover is arranged at the air outlet of the exhaust device, which plays a sound insulation role to avoid the working sound of the exhaust device being too loud to reduce the noise.

[0031] As Fig. 3 shown, the shell has a second plate 130 which is arranged perpendicularly to the first plate 110, that is to say, when the shell is a cuboid, the second plate 130 and the first plate 110 are adjacent and connected perpendicularly. The second plate 130 is provided with a window 131, the position of which corresponds to the position of the blades of the power device, so that the condition of the blades can be observed through the window 131. The window 131 can be formed by a through hole provided on the second plate 130 and a glass provided on the through hole.
