DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-6As shown, an integrated operating room purification system includes an air supply system 1 connected to multiple operating rooms 7 by means of an air supply duct 5, and an exhaust system 2 connected to multiple operating rooms by means of an exhaust duct 6, and a return air channel 8 that can be turned on or off is connected between the air supply system 1 and the exhaust system 2, a grouping integrated block 3 composed of multiple grouping units is arranged on the air outlet side of the air supply system 1, each grouping unit is respectively connected to at least one operating room 7, and each grouping unit respectively includes a heat coil Ⅰ31 and an electric air volume regulating valve Ⅰ32, and a monitoring integrated block 4 composed of multiple monitoring components is arranged on the air inlet side of the exhaust system 2, each monitoring component is respectively connected to at least one operating room 7, and each monitoring component respectively includes a temperature and humidity sensor 41.

[0030] Since different operating rooms 7 have different air temperature requirements, and the air temperature adjusted by the temperature and humidity adjustment chamber equipment of the air supply system 1 is lower than the air temperature required by all operating rooms 7, it can avoid the waste of resources caused by the need to cool down some operating rooms 7 again due to excessive air temperature. The heat coil Ⅰ31 on each grouping unit in the present invention is used to make the final temperature fine adjustment of the air in the operating room 7 connected to the grouping unit to meet the air temperature required by the operating room 7 and realize the separate temperature control of the channel of each grouping unit. The electric air volume control valve Ⅰ32 is used to adjust the air supply volume of the operating room 7 connected to the grouping unit.

[0031] Specifically, each heat coil Ⅰ31 is respectively arranged in a temperature adjustment chamber 33, and each temperature adjustment chamber 33 is integrated, and each electric air volume regulating valve Ⅰ32 is installed on the air outlet side of the corresponding temperature adjustment chamber 33, thereby forming a complete group integrated block 3.

[0032] Preferably, the air inlet and air outlet of each operating room 7 are provided with a separate electric air volume regulating valve III 71, which can realize the separate regulation of the air inlet and exhaust air volume of each operating room 71 with higher adjustment accuracy.

[0033] The grouping integrated block 3 integrates multiple grouping units to form an integral module which is installed on the air outlet side of the air supply system 1. Similarly, the monitoring integrated block 4 integrates multiple monitoring components into a whole which is installed on the air inlet side of the exhaust system 2. This can realize the integrated installation of the grouping integrated block 3, the monitoring integrated block 4 and the entire purification system, making the composition more convenient. In addition, the grouping integrated block 3 with a different number of grouping units and the monitoring integrated block 4 with a different number of monitoring components can be replaced as needed, thus having a wider scope of application.

[0034] When the fresh air is in operation, the fresh air entering the air supply system 1 from the outside contains a large amount of impurities and cannot be directly integrated into the operating room 7. The fresh air needs to be filtered, so the air supply system 1 also includes a primary and secondary efficiency filter 12 and a sub-high efficiency filter 13 connected to the fresh air duct 11 on its air inlet side.

[0035] Among them, the primary and secondary efficiency filters 11 include primary efficiency filters and secondary efficiency filters, which generally use non-woven chemical fiber filter materials. The primary efficiency filter is used to filter out particles with a particle size of ≥5μm in the new air, while the secondary efficiency filter is used to filter out particles with a particle size of ≥1μm in the new air. The filtration efficiency of both can reach 90% or above.

[0036] The sub-high efficiency filter 13 generally adopts glass fiber filter paper, which is used to filter out particles with a particle size of ≥0.5μm in the air. The filtration efficiency can reach 5% or above, and the filtration effect is good, ensuring the cleanliness of the air entering the operating room 7.

[0037] One end of the fresh air duct 11 is connected to the fresh air louver 14 , and the other end is connected to the air inlet side of the air supply system 1 .

[0038] Preferably, an electric air volume regulating valve II 15 is provided between the fresh air duct 11 and the air supply system 1, and is used to adjust the flow rate of fresh air.

[0039] Since the temperature and humidity of the air in the operating room 7 have specific requirements, the temperature and humidity need to be adjusted before the air is delivered to the operating room 7. The air supply system 1 also includes a temperature and humidity regulating chamber 16 connected to the air outlet side of the sub-high efficiency filter 13. The temperature and humidity regulating chamber 16 is provided with an electric heater 17, a cold coil 18, a fluorine coil 19, a hot coil II 110 and a humidifier 111.

[0040] Among them, the function of the electric heater 17 is to preheat the air. When the external environment temperature is low, and the temperature and humidity adjustment chamber 16 does not need to cool the air, that is, when the cold coil 18 and the fluorine coil 19 do not need to work, in order to prevent the cold air directly entering the temperature and humidity adjustment chamber 16 from freezing the cold coil 18, the electric heater 17 is used to preliminarily preheat the air to protect the cold coil 18. Therefore, the electric heater 17 is only suitable for situations where the external environment is low, such as winter.

[0041] The function of the cold coil 18 and the fluorine coil 19 is to cool the air, and is suitable for the case where the external ambient temperature is relatively high.

[0042] Preferably, in order to achieve the cooling effect of the fluorine coil 19 , the fluorine coil 19 is connected to the fluorine system outdoor unit 113 through the copper tube 112 .

[0043] When the external environment temperature is high, in order to reduce the humidity of the air, the fluorine coil 19 will reduce the temperature of the air entering the temperature and humidity adjustment chamber 16 to a temperature lower than the temperature required by the operating room 7. In order to increase the air temperature again, the heat coil II 110 is set. When the external environment temperature is low, since the electric heater 17 only preheats the air, the heat coil II 110 is required to heat the air twice. Therefore, the function of the heat coil II 110 is to heat the air. Compared with the case where the external environment temperature is high, the degree of heating is higher when the external environment temperature is low.

[0044] When the external environment temperature is low, such as in winter, the air is relatively dry and cannot meet the humidity requirement of the operating room 7, so a humidifier 111 is provided to adjust the humidity of the air.

[0045] In order to provide power for the air supply of the air supply system 1 , two air blowers 114 are connected in parallel on the air outlet side of the temperature and humidity adjustment chamber 16 , and the air outlet side of the air blowers 114 is connected to the grouping integrated block 3 .

[0046] The two air blowers 114 are provided to avoid problems with the normal use of the operating room 7 due to the failure of the air blowers 114. When the entire air supply system 1 is operating normally, the two air blowers 114 work at the same time. When one of the air blowers fails, the other air blower 114 can operate at 80% of the air supply volume of the air supply system 1 to ensure the normal use of the operating room 7.

[0047] In order to ensure the stability of the air delivered to the operating room 7, a Venturi tube Ⅰ91 and a silencer straight pipe Ⅰ92 are installed on the air outlet side of each grouping unit, and the Venturi tube Ⅰ91 and silencer straight pipe Ⅰ92 corresponding to each grouping unit form an air supply integrated block 9.

[0048] The function of the venturi tube Ⅰ91 is to stabilize the air volume, while the muffler straight pipe Ⅰ92 is to reduce the noise generated when the air is supplied. The venturi tube Ⅰ91 and the muffler straight pipe Ⅰ92 are integrated, which can facilitate the overall installation of the grouping integrated block 3, and the operation is more convenient.

[0049] In order to ensure the stability of the air exhausted from the operating room 7, each monitoring component also includes a Venturi tube II 42 and a silencer straight pipe II 43.

[0050] Likewise, the Venturi tube II 42 is used to stabilize the air volume, and the silencer straight pipe II 43 is used to eliminate the noise generated during the exhaust process.

[0051] Specifically, the silencer straight pipe II 43 is installed on the air inlet side of the temperature and humidity sensor 41 , and the venturi tube II 42 is installed on the air outlet side of the temperature and humidity sensor 41 .

[0052] The air exhausted from the operating room 7 will be mixed with some pollutants. If it is discharged directly into the atmosphere, it will inevitably cause pollution to the atmosphere. Therefore, the exhaust system 2 also includes a medium efficiency filter 21 connected to the monitoring integrated block 4, and the return air duct 8 is arranged on the air inlet side of the medium efficiency filter 21 and is connected to the air outlet side of the primary medium efficiency filter 12.

[0053] Among them, the medium and high efficiency filter 21 uses glass fiber filter paper to filter out particles with a particle size of ≥ 0.5μm in the exhausted air, with a filtration efficiency of 96%, ensuring that the impact on the atmosphere is minimized.

[0054] Preferably, in order to increase the integration level of the entire purification system, the air supply system 1 and the air exhaust system 2 are arranged in parallel on both sides of a steel support 10 .

[0055] In order to facilitate exhausting the air in the operating room 7 , the exhaust system 2 further includes an exhaust fan 22 connected to the medium-efficiency filter 21 , and an exhaust pipe 23 is installed on the exhaust fan 22 .

[0056] Preferably, a check valve 24 is installed on the exhaust pipe 23 to prevent external air from entering the exhaust system 2 again through the exhaust pipe 23 .

[0057] In order to realize the operation of the return air channel 8 , the return air channel 8 is a hose 81 that runs through the steel support 10 between the air supply system 1 and the exhaust system 2 , and a normally closed electric air volume regulating valve 82 is installed on the hose 81 .

[0058] When the air supply system 1 and the exhaust system 2 operate normally, the normally closed electric air volume regulating valve 82 is in a closed state. When the exhaust fan 22 fails, the normally closed electric air volume regulating valve 82 opens, connecting the return air channel 8 to realize return air operation.

[0059] In order to realize air supply and exhaust to the operating room 7, the air supply duct 5 is connected to the air supply static pressure box 72 of the operating room 7, and the exhaust duct 6 is connected to the upper exhaust port 73 and the lower exhaust port 74 of the operating room 7.

[0060] Preferably, a high efficiency filter is provided in the air supply static pressure box 72 to further filter out air impurity particles.

[0061] The high efficiency filter can be made of glass fiber filter paper, which is used to filter out particles with a diameter of ≥0.5μm in the air. The filtration efficiency is 99.95%, and the filtration effect is good, thereby ensuring the cleanliness of the operating room 7.

[0062] The present invention filters the air sent into the operating room 7 through four steps of primary filtration, medium filtration, sub-high efficiency filtration and high efficiency filtration, thereby ensuring the freshness and cleanliness of the air in the operating room 7.

[0063] Specifically, the electric air volume regulating valve III71 of the air inlet of the operating room 7 is arranged on the air inlet side of the air supply static pressure box, while the electric air volume regulating valve III71 of the air outlet is installed at the upper air outlet 73 and the lower air outlet 74 respectively.

[0064] Preferably, silencer elbows Ⅰ51 and Ⅱ61 are installed on the air supply duct 5 and the exhaust duct 6, respectively, to further reduce the noise generated during the air circulation process and reduce noise pollution.

[0065] Preferably, the air supply duct 5 and the exhaust duct 6 are respectively provided with fire dampers Ⅰ52 and Ⅱ62 to improve the safety performance of each duct.

[0066] Preferably, an automatic control cabinet is installed on one side of the air supply system 1 for realizing automatic control of the air purification of each operating room 7 .

[0067] The three working modes of the purification system disclosed in the present invention are specifically implemented as follows:

[0068] (1) When the external ambient temperature is high, such as in summer, the external air needs to be cooled and dehumidified before being sent to the operating room 7. The processing process is as follows: the outdoor fresh air enters the air supply system 1 through the fresh air duct 11, and is filtered by the primary and secondary efficiency filter 12 and the sub-high efficiency filter 13 in turn, and then enters the temperature and humidity adjustment chamber 16. After being cooled and dehumidified by the cold coil 18 and the fluorine coil 19, it is heated by the hot coil II 110, and then sent to each group unit by the air supply fan 114. The air temperature is fine-tuned by the hot coil I 31 of the group unit according to the needs of the operating room 7 connected to it, and then sent to each operating room 7 through the air supply duct 5. The dirty air in the operating room 7 enters the exhaust duct 6 through the upper exhaust port 73 and the lower exhaust port 71. The temperature and humidity sensor 41 connected to the exhaust duct 6 can detect the temperature and humidity of the air in the operating room 7 connected thereto according to the air conditions in the exhaust duct 6. If it is within the specified standard range, the heat coil Ⅰ31 does not need to be adjusted. If it exceeds the specified standard range, the temperature of the heat coil Ⅰ31 is adjusted to adjust the temperature of the air sent into the operating room 7. The air exhausted from the operating room 7 is filtered by the medium efficiency filter 21 and then discharged into the atmosphere by the exhaust fan 22, thus realizing a cycle of fresh air operation.

[0069] (2) When the external ambient temperature is low, such as in winter, the external air needs to be heated and humidified before being sent to the operating room 7. The processing process is as follows: the filtered air first needs to be preheated by the electric heater 17, then heated by the heat coil II 110, humidified by the humidifier 111, and then sent to the operating room 7 in the same manner as above, and the air in the operating room 7 is discharged into the atmosphere by the exhaust system 2.

[0070] (3) The use of the return air channel 8 is to directly send the air discharged into the exhaust system 2 to the air inlet side of the sub-high efficiency filter 13 through the hose 81, and then enter the operating room 7 after being processed by the air supply system 1 to realize the return air operation.

[0071] The air supply system 1 can set the number of grouping units in the grouping manifold block 3, the number of air supply manifold blocks 9 and air supply channels 5 corresponding to the grouping units, and the number of monitoring components according to the needs of the operating room 7, and the number of operating rooms 7 corresponding to each grouping unit can be selected according to the different air requirement levels of different operating rooms 7. The grouping manifold block 3 and the air supply manifold block 9 are both installed as a whole on the air outlet side of the air supply system 1, and the monitoring manifold block 4 is also installed on the air inlet side of the exhaust system 2. When the purification system is connected to the operating room for purification work, it is only necessary to connect and install the air supply duct 5 and the exhaust duct 6 between the purification system and the operating room 7, as well as some water pipes for temperature and humidity adjustment. The entire installation process is simple and convenient, and the probability of failure is reduced.

[0072] In this embodiment, the grouping units include four groups, and for the air level requirements of Class I operating rooms, they are connected to a single grouping unit and a monitoring component, and for the air level requirements of Class III operating rooms, three operating rooms of this level can be connected to the same grouping unit and a monitoring component. Therefore, the purification system provided in this embodiment can simultaneously achieve air purification for 10 operating rooms 7.

[0073] Specifically, taking the fresh air intake volume of 30,000 m³ / h as an example, the air supply volumes of the four grouping units adjusted by the electric air volume regulating valve Ⅰ32 are 1,000 m³ / h, 6,600 m³ / h, 6,600 m³ / h and 6,600 m³ / h respectively, among which the grouping units with air supply volumes of 1,000 m³ / h are connected to a Class I operating room, and each grouping unit with air supply volume of 6,600 m³ / h is connected to three Class III operating rooms respectively, and the air supply volume allocated to each Class III operating room is 2,200 m³ / h, which can fully meet the air requirements of the operation. During the exhaust process, the exhaust volume of the Class I operating room is 9,460 m³ / h, while the total exhaust volume of the three Class III operating rooms connected to the same grouping unit is 5,200 m³ / h, and the final exhaust volume of the exhaust fan is 25,000 m³ / h. The whole process can fully meet the requirements for purification of 10 operating rooms 7.

[0074] The purification system of the present invention greatly reduces the number of units and equipment installation space. At the same time, the system adopts a heat recovery system that can switch between fresh air and return air modes at will, which meets the demand for return air in summer and the demand for fresh air in transitional seasons. When a heat recovery system is set up, the demand for fresh air operation of the air conditioning system can also be met in summer. It solves the contradiction between fresh air and high energy consumption, improves air quality and reduces energy consumption.

[0075] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
