[0023] The utility model is further explained in connection with the drawings and specific embodiment, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model. Example one
[0024] Refer to Figure 1 The utility model discloses a boiler room freeze -proof system, for preventing the equipment freeze -out located in the lower portion of boiler room, including,
[0025] Air supply fan 1, air supply fan 1 is provided with multiple groups, and multiple groups of air supply fan 1 are vertically set in the air supply port of the top of boiler room A and are set up,
[0026] The exhaust pipe 2 is provided with a plurality of exhaust pipes 2, which are vertically connected to the side walls in the boiler room A respectively. One end of the exhaust pipe 2 is close to the bottom of the boiler room, and the other end penetrates the top of the boiler room and communicates with the outside;
[0027] The heat exchange fin 3 is provided with a plurality of heat exchange fins 3, which are connected to the side of each exhaust pipe 2 and close to the top of the boiler room.
[0028] Specifically, a plurality of exhaust pipes 2 are evenly spaced and installed on the side walls inside the boiler room. One end of each exhaust pipe 2 is arranged close to the ground of the boiler room, and the other end extends vertically upward and penetrates the roof of the boiler room to communicate with the outside. When the temperature difference between the upper and lower parts of the boiler room is large (i.e. the temperature of the upper part of the boiler room is high), the air supply fan 1 located at the top of the boiler room is started to introduce cold air from the outside into the interior of the boiler room. The mixed air formed by the mixing of the outdoor cold air and the hot air in the upper part of the boiler room has a lower temperature and a higher density, and gradually moves to the lower part of the boiler room. During the process of the mixed air gradually moving downward, the temperature of the upper part of the exhaust pipe 2 increases due to the heat exchange fin 3 (the heat exchange fin 3 absorbs heat from the upper part of the boiler room to heat the upper part of the exhaust pipe 2) on the exhaust pipe 2, which accelerates the upward discharge of the air in the upper part of the exhaust pipe 2, thereby accelerating the chimney effect of the air flow in the exhaust pipe 2 from bottom to top. In this way, the lower part of each exhaust pipe 2 will suck the air in the lower part of the boiler room, which will further accelerate the downward movement of the mixed air in the upper part of the boiler room. Finally, an air circulation is formed in the boiler room from top to bottom, which utilizes the high-temperature air in the upper part of the boiler room to heat and warm the environment in the lower part of the boiler room, thereby preventing the equipment in the boiler room from icing and frosting and ensuring the normal operation of the system.
[0029] Further, the boiler room anti-freezing system further comprises a first air valve 4. A plurality of air inlets close to the top of the boiler room are formed on the side of the boiler room, and the first air valve 4 is provided with a plurality of first air valves 4 and is installed on each air inlet. When the temperature of the high-temperature air in the upper part of the boiler room decreases to a certain extent, the air supply fan 1 can be closed and the first air valve 4 can be opened. The suction of the lower end of the exhaust pipe 2 in the lower part of the boiler room allows the outside air to enter the boiler room through the first air valve 4, and the cold air entering from the outside further reduces the temperature of the air in the upper part of the boiler room, so that the air in the upper part of the boiler room moves downward, thereby realizing the downward movement of the air in the boiler room and the discharge of the air through the exhaust pipe 2. This can reduce the energy loss and reduce the cost.
[0030] Further, the boiler room is further provided with a plurality of regulating fans 5, which are vertically arranged at the middle part of the boiler room. When the temperature difference between the upper and lower parts of the boiler room is large, the regulating fans 5 can be started to accelerate the introduction of outdoor cold air, so as to accelerate the circulation of air in the boiler room, quickly reduce the temperature difference between the upper and lower parts of the boiler room, and ensure the normal operation of the equipment. Specifically, the regulating fans 5 can assist the air supply fan 1 to introduce outdoor cold air from the air supply port at the top of the boiler room, or directly introduce cold air from the outdoor through the air pipe extending to the outdoor, which can be set according to actual needs.
[0031] Further, the boiler room is further provided with a plurality of regulating fans 5, which are vertically arranged at the middle part of the boiler room. When the temperature difference between the upper and lower parts of the boiler room is large, the regulating fans 5 can be started to accelerate the introduction of outdoor cold air, so as to accelerate the circulation of air in the boiler room, quickly reduce the temperature difference between the upper and lower parts of the boiler room, and ensure the normal operation of the equipment. Specifically, the regulating fans 5 can assist the air supply fan 1 to introduce outdoor cold air from the air supply port at the top of the boiler room, or directly introduce cold air from the outdoor through the air pipe extending to the outdoor, which can be set according to actual needs.
[0032] Further, the heat exchange sheet 3 comprises an arc-shaped base plate, which is connected to one side of the exhaust air pipe 2 away from the side wall of the boiler room through fasteners, and a plurality of fins are vertically connected to the base plate.
[0033] Further, in order to ensure that the exhaust air pipe 2 has an effective temperature difference, a first heat preservation layer can be added to the section of the exhaust air pipe 2 extending out of the boiler room, so as to avoid the low temperature outside from reducing the temperature at the upper end of the exhaust air pipe 2.
[0034] Further, the second heat insulation layer is arranged on the side of each exhaust pipe 2 close to the side wall of the boiler room. Specifically, in order to ensure that the exhaust pipe 2 can make better use of the temperature difference, the heat insulation layer is arranged on the side of the exhaust pipe 2 close to the side wall of the boiler room, so that the low-temperature side wall of the boiler room does not affect the temperature inside the exhaust pipe 2; and no heat insulation layer is arranged on the side of the exhaust pipe 2 close to the boiler B, so that the exhaust pipe 2 can be normally heated by the high-temperature air on the upper part of the boiler room.
[0035] Further, the diameter of each exhaust pipe 2 gradually decreases from the end close to the bottom of the boiler room to the end close to the top of the boiler room. It can be considered that the design of the exhaust pipe 2 with a large diameter at the lower part and a small diameter at the upper part can keep the air flow rate unchanged or slightly increased, thereby preventing the cold air outside from flowing into the exhaust pipe 2.
[0036] Further, the top of each exhaust pipe 2 is provided with a rain cover to prevent rainwater from entering the boiler room from the exhaust pipe 2. Preferably, the input port 21 of the exhaust pipe 2 is located on the side of the exhaust pipe, which is beneficial to the rapid flow of air in the boiler room.
[0037] The boiler room anti-freezing system of the utility model, through setting up the air supply fan 1 makes the hot air gathered on the upper part of the boiler room move from top to bottom, and through setting up multiple exhaust pipes 2 and using the heat exchange sheet 3 arranged on the exhaust pipe 2 to utilize the heat of the hot air on the upper part of the boiler room, makes the air in the exhaust pipe 2 flow from bottom to top, thereby can suck the air inside the boiler room, finally forms the air flow circulation from top to bottom in the boiler room, makes the high-temperature air originally in the upper part of the boiler room can heat the environment of the lower part of the boiler room, ensures the normal operation of the equipment, and also can provide a comfortable working environment for the staff. Embodiment two
[0038] Referring to Figure 2 As shown in the embodiment one, on the basis of the boiler room anti-freezing system, the structure thereof can be simplified, the simplified boiler room anti-freezing system removes the air supply fan 1 and the control fan 5, only sets up the first air valve 4, the exhaust pipe 2 and the heat exchange sheet 3 and the like structure, utilizes the chimney effect of the exhaust pipe 2 to suck the air of the lower part of the boiler room, the outdoor air enters the boiler room through the first air valve 4, the outdoor cold air lowers the temperature of the air on the upper part of the boiler room, so that the air on the upper part of the boiler room moves downward, thereby also can realize the movement of the air inside the boiler room from top to bottom.
