Description

Technical Field

[0001] The utility model relates to the field of environmental protection, in particular to sewage treatment equipment. Background Art

[0002] During biological wastewater treatment, a large number of blowers are required for aeration and ventilation. There are various types of blowers, such as Roots blowers and multi-stage centrifugal blowers. These blowers are typically installed in a centralized location within a blower room. Piping connects the blower inlet to the outside of the room, while piping extends the blower outlet to the target device / equipment / structure.

[0003] Existing multi-stage centrifugal fans compress the air they deliver during operation, causing the temperature of the final-stage casing to reach over 100°C, and even over 120°C in summer. For safety and dust protection, workshops also install protective enclosures around the multi-stage centrifugal fans. These enclosures are equipped with ventilation and heat dissipation holes to allow heat dissipated by the fans to escape the enclosure.

[0004] In recent years, summer heatwaves have become increasingly severe. The high temperatures and prolonged duration of these temperatures have resulted in consistently high ambient temperatures within the fan room. Furthermore, the continuous operation of electrical equipment within the fan room further increases the ambient temperature, placing workers at particularly high risk of heatstroke. Furthermore, the local ambient temperature within the protective enclosure can reach over 50°C, exceeding the maximum operating temperature specified in the fan manual and potentially causing equipment failure. If the protective enclosure is equipped with independent cooling devices, these devices will only be used at specific times and stages of the year, resulting in long periods of idle time and low utilization. Utility Model Content

[0005] To solve the problem of excessively high temperatures in the fan room and the blower operating environment in summer, this utility model provides a device that can simultaneously cool the blower room and locally cool the blower protective box. The main technical solutions adopted are as follows:

[0006] A blower room cooling system includes a machine room, wherein the machine room is provided with a plurality of blower systems. The main features of the system are: a plurality of air coolers are installed outside the machine room, all of the air coolers are located outside the same side wall of the machine room, the air outlets of the air coolers are provided on the wall of the machine room and blow air into the machine room, and the air outlets of the air coolers are located at the lower part of the machine room;

[0007] A plurality of exhaust fans are provided on the wall of the machine room opposite to the air cooler, and the exhaust fans are close to the top of the machine room;

[0008] The air blowing system includes a protective box and a blower assembly arranged inside the protective box. The protective box is provided with a forced heat dissipation window. A detachable air duct is arranged between the air outlet of the cooling fan and the forced heat dissipation window.

[0009] The air cooler is an industrial air cooler. The air cooler and exhaust fan work together to dissipate heat from the fan room, lowering the ambient temperature. Furthermore, if the temperature in a certain area of ​​the protective box is too high, a removable air duct can be installed to cool the area to ensure proper operation of the equipment. The removable air duct can be removed and not used during periods of low temperatures.

[0010] The advantages of adopting the above technical solution are: small investment, low cost, short transformation cycle, no impact on production, switchability, strong targeting and significant effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0017] like Figure 1 、 2 As shown in Figures 3, 4 and 5, a cooling system for a blower room includes a room 1, wherein the room 1 is provided with a plurality of blower systems 2.

[0018] Several air coolers 3 are installed outside the machine room 1. All of the air coolers 3 are located outside the same side wall of the machine room 1. The air outlets of the air coolers 3 are provided on the wall of the machine room 1 and blow air into the machine room 1. The air outlets of the air coolers 3 are located at the lower part of the machine room 1.

[0019] A plurality of exhaust fans 5 are provided on the wall of the machine room 1 opposite to the air cooler 3, and the exhaust fans 5 are close to the top of the machine room 1;

[0020] The air cooler 3 can be an industrial cooling fan. The air cooler 3 and the exhaust fan 5 cooperate with each other. The air cooler 3 delivers cold air to the bottom of the machine room 1. The hot air in the machine room 1 rises to the top and is extracted by the exhaust fan 5, thereby reducing the temperature in the machine room 1 in high temperature seasons.

[0021] The blower system 2 includes a protective box 21 and a blower assembly arranged inside the protective box 21. The protective box 21 is a cubic box. The box wall of the protective box 21 is provided with a plurality of heat dissipation holes. The air inlet of the blower assembly passes through the protective box 21 and the machine room 1 through a pipe, and draws air from outside the machine room 1. An air filter device is provided in the pipe connected to the air inlet of the blower assembly. The air outlet of the blower assembly passes through the protective box 21 and the machine room 1 through a pipe and extends to the target device (for example: aeration pipe network).

[0022] The blower assembly generates heat during operation. In spring, autumn, and winter, the heat generated by the blower assembly is insufficient to cause the ambient temperature within the protective box 21 to rise excessively. However, during certain periods of summer, the local ambient temperature within the protective box 21 may far exceed the operating limit of the blower assembly, necessitating cooling of the interior of the protective box 21. To prioritize addressing the issue of short-term excessive ambient temperatures within the protective box 21, a forced heat dissipation window is provided on the protective box 21. A removable air duct 4 is positioned between the air outlet of the air cooler 3 and the forced heat dissipation window.

[0023] As a preferred technical solution, the side wall of the protection box 21 facing the air cooler 3 is provided with the forced heat dissipation window to reduce the length of the detachable air duct 4 and avoid the detachable air duct 4 from turning.

[0024] In addition, the detachable air duct 4 is a telescopic bellows, so that the detachable air duct 4 can be stored after disassembly. The two ends of the telescopic bellows are connected to the air cooler 3 and the forced heat dissipation window through air duct hooks 41 respectively.

[0025] A further preferred solution is:

[0026] A circle of reinforcing cloth strips 42 are sewn around the ends of the telescopic bellows around its pipe opening, and the root of the air duct hook 41 is connected to the reinforcing cloth strips 42. This can enhance the connection strength between the air duct hook 41 and the telescopic bellows.

[0027] When there is no need to dissipate heat and cool the inside of the protective box 21, in order to facilitate opening or closing the forced heat dissipation window, a window cover 22 is covered on the forced heat dissipation window. The window cover 22 is hinged to the protective box 21 around the forced heat dissipation window. The outer wall of the protective box 21 is provided with a cover pin 23, and the window cover 22 is provided with a pin hole, and the cover pin 23 matches the pin hole.

[0028] The inner wall of the protective box 21 is provided with at least two box hanging ears 24, all of which are arranged around the forced heat dissipation window, a portion of the box hanging ears 24 extends into the forced heat dissipation window, and a box hanging hole is provided on the extended portion of the box hanging ears 24;

[0029] The air duct hook 41 at the outlet end of the telescopic bellows is hung with the hanging hole of the box.

[0030] A circle of air outlet side plates 31 are provided at the air outlet of the air cooler 3, and at least two fan hanging holes are provided on the air outlet side plates 31, and all the fan hanging holes are provided around the air outlet of the air cooler 3;

[0031] The air duct hook 41 at the inlet end of the telescopic bellows is hung with the fan hanging hole.

[0032] Generally speaking, the telescopic bellows is a round tube, while the air outlet of the air cooler 3 is square. The forced heat dissipation window can match the telescopic bellows and is also designed / manufactured in a round shape. A transition pipe can be installed between the air outlet of the air cooler 3 and the telescopic bellows to ensure a tight connection between the two.

[0033] The air outlet of the air cooler 3 can also be directly connected to the telescopic bellows. In this case, part of the cold air blown by the air cooler 3 enters the protective box 21, and part enters the machine room 1. The amount of cold air from the two streams can be adjusted by varying the diameter of the telescopic bellows. Of course, due to the different interfaces between the air outlet of the air cooler 3 and the telescopic bellows, in order to enable the air duct hook 41 to be hung with the fan hanging hole, an adjustable length rope is also connected between the inlet end of the telescopic bellows and the corresponding air duct hook 41.

[0034] Beneficial effect: The technical solution of the utility model is adopted to fully utilize the cooling equipment, avoiding equipment idleness, which can not only solve the high-temperature heat dissipation problem in the blower room, but also solve the problem of local high-temperature heat dissipation inside the fan protection box; it has the advantages of small investment, low cost, switchability and strong targeting.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
