Description

Technical Field

In addition, the utility model also relates to a plateau pressure-bearing building including the above-mentioned plateau pressure-bearing building pressurization system. Background Technique

[0002] In high-altitude areas, due to the thin air, the air pressure is low and the oxygen content is small. People living in such an environment for a long time are prone to various altitude diseases, which affect work efficiency and endanger personal health. To solve these problems, it is necessary to pressurize and supplement oxygen in the living and working areas of people. Therefore, many enterprises have developed plateau oxygen chambers for people from low-altitude areas to live temporarily to relieve altitude sickness.

[0003] To solve the above problems, the prior art such as patent number 202123422033.X discloses a device for a transition area of a plateau pressure-bearing building. By setting a transition area, the pressure in the transition area is relieved to be the same as the outdoor pressure before entering the room, and the pressure is gradually increased to be the same as the indoor pressure after entering the transition area. Similarly, when leaving the room, the pressure in the transition area is increased to be the same as the indoor pressure, and the pressure is gradually relieved to be the same as the outdoor pressure after entering the transition area, so that people can leave the building. And the indoor needs to continuously supply air through equipment such as a fan to maintain the indoor pressure. During the air supply process, the indoor is affected by the fan and the air supply noise, and the flow noise is more serious after the valve in the transition area is opened during the process of balancing the pressure difference, resulting in poor comfort.

The pressurization device includes a sound insulation box body and a fan arranged in the sound insulation box body. The sound insulation box body is provided with an air inlet communicating with the outdoor, and the air inlet is provided with a filtering device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will elaborate on the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0024] Figure 1 is a structural schematic diagram of a preferred embodiment of the present utility model; Figure 2 is a structural schematic diagram of the sound insulation box body of a preferred embodiment of the present utility model.

[0025] As Figure 1 and Figure 2 shown, the high-altitude pressure-bearing building pressurization system of this embodiment includes a transition area 200 and a pressure-bearing area 100, and also includes an equipment area 300. A first transition door is provided between the transition area 200 and the outdoors, and a second transition door is provided between the transition area 200 and the pressure-bearing area 100. The transition area 200 is provided with a pressurization component communicating with the pressure-bearing area 100 and a pressure relief component communicating with the outdoors; a pressurization device 1 and a control device 13 are provided in the equipment area 300. The pressurization device 1 includes a sound insulation box body 102 and a blower 101 arranged in the sound insulation box body 102. The sound insulation box body 102 is provided with an air inlet communicating with the outdoors, and a filtering device is provided at the air inlet. The sound insulation box body 102 is provided with a heat dissipation device electrically connected to the control device 13 and a heating device electrically connected to the control device 13. The air outlet of the blower 101 is communicated with the pressure-bearing area 100 through an air supply pipe. The control device 13 is used to respectively control the opening and closing of the pressurization component, the opening and closing of the pressure relief component, the rotation speed of the blower 101, the start and stop of the heating device, and the start and stop of the heat dissipation device.

[0026] Among them, the control device 13 is implemented based on the controller of the high-altitude pressure-bearing building in the prior art; the sound insulation box body 102 includes a top plate 112, two side plates 111, a back plate 114, a front panel 115, and a bottom plate 113. Adjacent plates are fixed using lock catches for disassembly and maintenance; each plate is constructed as a sound insulation cotton with a thickness of 50 mm sandwiched between two galvanized thin plates, and the galvanized steel plate arranged towards the inner side of the sound insulation box body 102 adopts a stamping and perforation process; the heating device is a heater 118 installed on the back plate 114; the filtering device is a filter 117 installed on the front panel 115; the heat dissipation device can be an exhaust fan 116 installed on the top plate 112; it should be understood that a temperature sensor 119 electrically connected to the control device 13 is provided in the sound insulation box body 102 to monitor the internal temperature of the sound insulation box body 102 and realize the automatic control of the start and stop of the exhaust fan 116 and the start and stop of the heater 118.

[0027] It can be understood that when a person goes outdoors, the control device 13 turns on the pressurizing component to pressurize the transition area 200 according to the pressure difference between the transition area 200 and the pressure-bearing area 100, so that the pressures of the two areas are balanced. Then the second transition door is opened, and the person can enter the transition area 200. Subsequently, the second transition door is closed, and after depressurizing through the depressurizing component until the pressure is balanced with the outdoor atmospheric pressure, the first transition door is opened, and the person can leave the transition area 200 to the outdoors. Similarly, when a person enters the room, the control device 13 turns on the depressurizing component to balance the pressure between the transition area 200 and the outdoors. The first transition door is opened, and after the person enters the transition area 200, the first transition door is closed. Then the pressurizing component is turned on to increase the pressure until it is balanced with the pressure of the pressure-bearing area 100, and then the second transition door can be opened to enter the pressure-bearing area 100. This pressurization system is controlled by the control device 13 to keep the speed of the fan 101 constant to maintain the pressure in the pressure-bearing area 100. By setting the sound-insulating box 102 and integrating the fan 101, the heating device, and the heat dissipation device in the sound-insulating box 102, the maintenance is convenient. It also has the functions of noise reduction, air exhaust, and preheating, improving the noise comfort level and ensuring that the fan 101 can be used in a low-temperature environment.

[0028] In this embodiment, a first pressure detection unit 9 electrically connected to the control device 13 is provided in the pressure-bearing area 100, and a second pressure detection unit 11 electrically connected to the control device 13 is provided in the transition area 200. Both the first pressure detection unit 9 and the second pressure detection unit 11 are pressure sensors. The control device 13 controls the speed of the fan 101 according to the pressure in the pressure-bearing area 100 detected by the first pressure detection unit 9 to increase the pressure in the pressure-bearing area 100 to the set value or control the speed of the fan 101 to maintain the pressure in the pressure-bearing area 100 stable. When a person goes outdoors, the control device 13 determines whether there is a pressure difference based on the detected pressures in the pressure-bearing area 100 and the transition area 200. If there is a pressure difference, the pressurizing component is turned on to balance the pressures of the two areas, and the person can enter the transition area 200. Subsequently, after depressurizing through the depressurizing component until the pressure is balanced with the outdoor atmospheric pressure, the person can leave the transition area 200 to the outdoors. Similarly, when a person enters the room, the control device 13 detects whether there is a pressure difference between the transition area 200 and the outdoors. If there is a pressure difference, the depressurizing component is turned on to balance the pressure between the transition area 200 and the outdoors. After the person enters the transition area 200, the pressurizing component is turned on to increase the pressure until it is balanced with the pressure of the pressure-bearing area 100, and then the person can enter the pressure-bearing area 100.

[0029] In this embodiment, an identification device 12 electrically connected to the control device 13 is provided in the transition area 200, which is used to detect whether there is a person in the transition area 200 and feedback it to the control device 13. The identification device 12 can be an infrared sensor or a face recognition device.

[0030] Furthermore, the pressurization assembly includes a pressurization valve 4 and an indoor bypass valve 5, and the pressure relief assembly includes a pressure relief valve 6 and an outdoor bypass valve 7. Resistive mufflers are respectively installed at the inlets and outlets of the pressurization valve 4 and the pressure relief valve 6. Based on the above structure, during the pressurization process, if the recognition device 12 detects someone in the transition area 200, the controller controls the pressurization valve 4 to open, so that the flow noise caused by the high pressure difference is suppressed by the resistive muffler. After the pressure difference between the transition area 200 and the pressure-bearing area 100 is less than a preset value (for example, 2 kPa), the indoor bypass valve 5 is controlled to open to quickly balance the residual pressure difference. During the pressurization process, if the recognition device 12 detects no one in the transition area 200, the pressurization valve 4 and the indoor bypass valve 5 are controlled to open simultaneously for rapid pressurization. The same applies during pressure relief; that is, before a person enters the transition area 200 from outside, rapid pressure relief can be achieved, or before going outside and entering the transition area 200, rapid pressurization can be achieved. When in the transition area 200, the noise impact can be significantly reduced. Based on this structure, while ensuring the noise comfort of personnel in the transition area 200, the pressure balance problem caused by the pressure loss of the resistive muffler is compensated, and the waiting time for entering and leaving can be significantly shortened.

[0031] In this embodiment, an air quality detection device 10 and an exhaust valve 3 electrically connected to the control device 13 are provided in the pressure-bearing area 100. Based on the settings of the air quality detection device 10 and the exhaust valve 3, when the pressure value in the pressure-bearing area 100 reaches the preset value, the exhaust valve 3 starts to exhaust, and the rotational speed of the fan 101 is adjusted to balance the pressure in the pressure-bearing area 100. Based on the detection result of the air quality detection device 10, if the carbon dioxide concentration increases, the opening degree of the exhaust valve 3 and the rotational speed of the fan 101 are synchronously increased to increase the exhaust flow rate and the supply air flow rate to maintain pressure balance. Similarly, when both decrease, pressure balance is maintained, and the air quality and energy consumption are reduced simultaneously;

[0032] Among them, a pressure limiting valve 8 communicating with the outside is provided in the pressure-bearing area 100 to limit the maximum pressure in the pressure-bearing area 100 and prevent the pressure in the pressure-bearing area 100 from exceeding the maximum pressure due to factors such as faults.

[0033] In this embodiment, the fan 101 is installed on the inner bottom surface of the sound insulation box 102 through a shock pad 120, that is, installed on the bottom plate 113, further reducing the noise impact.

[0034] In this embodiment, multiple branch pipes are provided at the end of the air supply pipe to reduce the air supply speed. An air supply box 2 is provided in the pressure-bearing area 100 at the outlet end of the branch pipe. A noise reduction structure is provided in the air supply box 2 to effectively reduce the wind noise and ensure the indoor noise comfort. An ultraviolet sterilization lamp is provided in the air supply box 2 to improve the air quality of the supply air at the same time.

[0035] Furthermore, a reduced-diameter pipe is provided on the branch pipe located upstream to make the air supply volume of each branch pipe tend to be consistent, ensuring that the flow losses from the outlet of the fan 101 to the ends of each branch pipe are equivalent, and the indoor pressure is more balanced and stable.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
