  • Detailed Description of the Embodiments
  • In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the implementations of the present disclosure will be described in further detail below with reference to the accompanying drawings.
  • Referring to Fig. 1, a clean workshop capable of being controlled by partition disclosed by an embodiment includes a workshop body 270. The workshop body 270 is internally provided with a lower technical interlayer 110, an upper technical interlayer 100, and a clean production layer located between the upper technical interlayer 100 and the lower technical interlayer 110. The clean production layer is internally provided with a clean room. Two sides of the clean room are provided with a first return air passageway 130 and a second return air passageway 140 configured to communicate the upper technical interlayer 100 and the lower technical interlayer 110. The workshop body 270 is further internally provided with a partition wall component to separate the clean room into a first clean production area and a second clean production area independent of each other. The first clean production area and the second clean production area each have an independent return air system.
  • In the embodiment of the present disclosure, the clean room is separated, by the partition wall component, into the first clean production area and the second clean production area independent of each other, the first clean production area and the second clean production area each have the independent return air system, when the first clean production area and the second clean production area are in an operating state, air supply volumes can be controlled by the independent return air systems, circulation of an airflow is realized, and thus requirements of the first clean production area and the second clean production area for cleanliness, temperature, relative humidity and VOC concentration are guaranteed respectively. In addition, separately controlling the air supply volume of each clean production area can facilitate reduction of energy consumption, so as to reduce costs.
  • In the related art, one situation is that a cleanliness level of the clean room is maintained by sending clean air into the room through fan filter units disposed on suspended ceilings, and discharging suspended particles in the room from a return air port. A traditional clean workshop, as shown in Fig. 1, includes a workshop body 270. The workshop body 270 is internally provided with an upper technical interlayer 100, a lower technical interlayer 110, and a clean production layer located between the upper technical interlayer 100 and the lower technical interlayer 110. The clean production layer is internally provided with an overhead waffle board 190 and a clean room 120 disposed on the waffle board 190. The clean room 120 includes raised floors 150 located on the waffle board 190, suspended ceilings 160, and wall boards matched with the raised floors 150 and the suspended ceilings 160. Two sides of the clean room 2 are provided with a first return air passageway 130 and a second return air passageway 140 configured to communicate the lower technical interlayer 5 and the upper technical interlayer 6. Dry cooling coils 220 configured to cool circulating air are disposed between the lower technical interlayer 110 and the first return air passageway 130 as well as between the lower technical interlayer 110 and the second return air passageway 140.
  • There are three parts in the clean room 120 that need to ensure air cleanliness. They are a material storage area 171, a material transfer area 172, and process production areas 125 respectively. The material storage area 171 is provided with material storage racks 230 configured to store materials such as glass substrates and chips to be processed. The material transfer area 172 is internally provided with an automatic conveying apparatus. Process production devices are usually arranged in the process production areas 125, and the process production areas 125 are also activity areas for operators. Since the glass substrates, chips, etc. to be processed in the material storage area 171 and the material transfer area 172 are in direct contact with ambient air, the air cleanliness level in this space is usually much stricter than the air cleanliness level in the process production areas 125.
  • A plurality of fan filter units 210 are arranged on suspended ceilings 160 of the process production areas 125, and in order to ensure the strict cleanliness level of a material storage and transfer area 170, a suspended ceiling 160 of the material transfer area 172 is usually covered with fan filter units 210, and side faces of the material storage racks 230 are highly densely provided with fan filter units 210. An air circulation path of a whole purification air conditioning system of the clean room is shown as arrows in Fig. 1. Since the fan filter units 210 installed on the side faces of the material storage racks 230 suck in air in the process production areas 125, the suspended ceilings 160 of the process production areas 125 need to be additionally provided with fan filter units with the same air volume as the fan filter units installed on the side faces of the material storage racks 230, resulting in a large increase in the quantity of fan filter units 210 that need to be installed on the suspended ceilings 160 of the process production areas 125, and also resulting in an increase of energy consumption.
  • In addition, the cleanliness level requirements of the material storage area 171 and the material transfer area 172 are very strict, the air supply volume ensuring the cleanliness level needs to be very large, but devices in these areas generate very little heat, so only a very few part of an air flow flowing through the areas needs to be cooled, but according to a traditional construction method of the clean room 120 shown in Fig. 1, airflows sucked in by the fan filter units 210 installed at the top of the material transfer area 172 and installed on the side walls of the material storage racks 230 are both airflows processed by the dry cooling coils 220. At the same time, all airflows flowing out of the process production areas 125 and the material transfer area 172 pass through the dry cooling coils 220 after entering the lower technical interlayer 110, resulting in an additional increase in the quantity of the dry cooling coils 220, and causing a failure to arrange the dry cooling coils 220 in a specified space in many projects. In addition, the air flows delivered out of the process production areas 125 and the material transfer area 172 all pass through a technical passageway 7 and the upper technical interlayer 100, which enlarges a space required by the return air passageways and the upper technical interlayer 100, and increases construction costs.
  • In view of this, in an embodiment, as shown in Fig. 2, in the clean room of this embodiment, the clean room is disposed on an overhead waffle board 190, and the clean room further includes suspended ceilings 160 on an upper portion and wall boards matched with the suspended ceilings 160. Dry cooling coils 220 configured to cool circulating air are disposed between a lower technical interlayer 110 and a first return air passageway 130 as well as between the lower technical interlayer 110 and a second return air passageway 140.
  • The waffle board 190 is a concrete slab with evenly formed holes, and has supporting and ventilating functions. The clean room 2 includes the suspended ceilings 160 on the upper portions and the wall boards matched with the suspended ceilings 160. Two independent areas included by a first clean production area are process production areas 125. A space between the two process production areas 125 is a material storage and transfer area 170. Suspended ceilings of the material storage and transfer area 170 and the process production areas 125 are each provided with a plurality of fan filter units 210. As shown in Figs. 2 and 3, two sides of the material storage and transfer area 170 are respectively provided with the process production areas 125. The material storage and transfer area 170 is internally provided with a material storage rack group, and two sides of the material storage rack group are each provided a partition wall board 200. Atop of each partition wall board 200 extends to a top of the upper technical interlayer 100, and a bottom of each partition wall board 200 is connected with the waffle board 190. The material storage rack group includes two rows of material storage racks 230. A gap between each row of material storage rack 230 and an adjacent partition wall board 200 forms a third return air passageway 180, and each third return air passageway 180 communicates with the upper technical interlayer 100. Specifically, the third return air passageways 180 communicate with the upper technical interlayer 100 through holes formed in the suspended ceilings 160, and the holes formed in the suspended ceilings 160 are distributed in areas corresponding to the third return air passageways 180.
  • In the material storage and transfer area 170, the material storage racks 230 are configured to store materials such as glass substrates and chips to be processed. Areas where the material storage racks 230 are disposed are material storage areas 171. An area between the two rows of material storage racks 230 forms a material transfer area 172, and an automatic conveying apparatus is disposed in the material transfer area 172. In the material storage areas 171, a side wall of each row of material storage rack 230 is provided with a plurality of fan filter units 210 configured to suck in an airflow in the third return air passageways 180 and deliver the airflow into the corresponding material storage racks 230, that is, these fan filter units 210 may suck in the airflow entering the third return air passageways 180, and after filtering and pressuring the airflow, deliver the airflow to one side of each material storage rack 230, namely to the material storage areas 171, so as to dilute a concentration of suspended particles in the material storage areas 171 to maintain a cleanliness level requirement of the material storage areas 171. In the material transfer area 172, fan filter units 210 highly densely disposed at a top of the material transfer area 172 suck in an airflow in the upper technical interlayer 100, and after filtering and pressuring the airflow, deliver the airflow into the material transfer area 172, so as to dilute a concentration of suspended particles in the material transfer area 172 to maintain a cleanliness level requirement of the material transfer area 172.
  • In addition, in the material storage and transfer area 170, a bottom of each row of material storage rack 230 is provided with an airflow passage communicating the material transfer area 172 and each third return air passageway 180 adjacent to the material transfer area 172, that is, the third return air passageways 180 communicate with the material transfer area 172. In specific settings, a raised floor 150 is disposed between the bottom of each row of material storage rack 230 and the waffle board 190, and gaps between the raised floors 150 and the waffle board 190 form airflow passages. In addition, in the process production areas 125, raised floors 150 may further be disposed on the waffle board 190, and the raised floors 150 are provided with holes, so as to ensure communication between the process production areas 125 and the lower technical interlayer 110. Moreover, surfaces of the raised floors 150 are relatively flat, which facilitates arrangement of process production devices. Apparatuses such as pipes may further be arranged in the gaps between the raised floors 150 and the waffle board 190.
  • As shown in Fig. 2, the third return air passageways 180 communicate with the material transfer area 172 through the airflow passages at the bottoms of the material storage racks 230, and communicate with the lower technical interlayer 110 through the holes formed in the waffle board 190. One part of the airflow flowing out of the material transfer area 172 enters the third return air passageways 180 through the airflow passages at the bottoms of the material storage racks 230, and the other part enters the lower technical interlayer 110 through the holes in the waffle board 190. Most of the airflow entering the lower technical interlayer 110 also passes through, due to a path and pressure balance, the holes of the waffle board 190 to enter the third return air passageways 180, while a small part of the airflow enters a first return air passageway 130 and a second return air passageway 140 through the dry cooling coils 220. One part of an airflow in the third return air passageways 180 is sucked in by the fan filter units 210 disposed on the side walls of the material storage racks 230, is delivered out after being pressurized and filtered, and passes through the material storage racks 230 to enter the material transfer area 172. The other part of the airflow flows upwards into the upper technical interlayer 100, is sucked in by the fan filter units 210 disposed at the top of the material transfer area 172, and is delivered into the material transfer area 172 after being pressurized and filtered. It can be seen that after entering the third return air passageways 180, most of the airflow flowing out of the material transfer area 172 returns to the material transfer area 172 again through the fan filter units 210 disposed on the side walls of the material storage racks 230 and the fan filter units 210 arranged at the top of the material transfer area 172, which realizes local circulation. Because this part of in-situ circulating airflow no longer passes through the dry cooling coils 220, the first return air passageway 130, the second return air passageway 140 or the upper technical interlayer 100, the quantity of the dry cooling coils 220 may be greatly reduced, and a space occupied by the first return air passageway 130, the second return air passageway 140 and the upper technical interlayer 100 may also be reduced, and the construction cost of the clean room 2 is reduced. At the same time, because the third return air passageways 180 provide an air volume for the fan filter units disposed on the side walls of the material storage racks 230, tops of the process production areas 125 do not need to be additionally provided with the fan filter units 210 with the same air volume as the fan filter units 210 installed on the side faces of the material storage racks 230, which reduces the air supply volume of the process production areas 125 and the quantity of the fan filter units 210, and reduces energy consumption and construction costs. It is worth noting that in the structure shown in Fig. 2, the raised floors 150 may not be provided to reduce the construction costs.
  • Continuing to refer to Fig. 2, in order to ensure temperature and relative humidity parameters of the material storage and transfer area 170, a fresh air supply pipe 240 is disposed in the lower technical interlayer 110, and an air outlet port of the fresh air supply pipe 240 communicates with each third return air passageway 180. The fresh air supply pipe 240 is configured to deliver processed low-temperature air into the third return air passageways 180. In the third return air passageways 180, fresh air is mixed with a circulating air flow, and one part of a mixed airflow is sucked in by the fan filter units disposed on the side walls of the material storage racks, is delivered out after being pressurized and filtered, and passes through the material storage racks to enter the material transfer area. The other part of the mixed airflow flows upwards into the upper technical interlayer, is sucked in by the fan filter units disposed at the top of the material transfer area, and is delivered into the material transfer area after being pressurized and filtered. In specific settings, the fresh air supply pipe 240 may communicate with a fresh air processing unit of the clean room air conditioning system. Further, the fresh air supply pipe 240 is provided with an electric regulating valve 260, and a temperature sensor is disposed in the material storage and transfer area 170 or each third return air passageway 180. The electric regulating valve 260 and the temperature sensor are in signal connection with a control apparatus, and the control apparatus is configured to control an opening degree of the electric regulating valve 260 according to a temperature detected by the temperature sensor, so as to control an air supply volume of the fresh air supply pipe 240. In this way, the amount of fresh air delivered into the third return air passageways 180 may be controlled according to the temperature in the material storage and transfer area 170 or the third return air passageways 180, so as to accurately control temperatures of the material storage areas 171 and the material transfer area 172.
  • In order to further meet pressure requirements in the material storage and transfer area 170, as shown in Fig. 3, a sealing plate 250 is disposed at a bottom of the waffle board 190 corresponding to the material storage and transfer area 170 and the third return air passageways 180, and the sealing plate 250 is configured to separate bottoms of the material storage and transfer area 170 and the third return air passageways 180 from the lower technical interlayer 110. Or, a cover plate is disposed at tops of the holes in the waffle board corresponding to the material storage and transfer area and the return air passageways, and the cover plate is configured to separate the bottoms of the material storage and transfer area and the return air passageways from the lower technical interlayer, so that the material storage and transfer area and the third return air passageways 180 are completely separated from a surrounding environment, and an independent air circulation is formed between the material storage and transfer area and the third return air passageways 23. According to an airflow direction as shown by arrows in Fig. 3, the airflow flowing out from the material transfer area 172 enters the third return air passageways 180 through the airflow passages formed by the raised floors 150 and the waffle board 190, and is mixed with fresh air delivered by the fresh air supply pipe 240. One part of a mixed airflow is sucked in by the fan filter units 210 disposed on the side walls of the material storage racks 230, is delivered out after being pressurized and filtered, and passes through the material storage racks 230 to enter the material transfer area 172. The other part of the mixed airflow flows upwards into the upper technical interlayer 100, is sucked in by the fan filter units 210 disposed at the top of the material transfer area 172, is delivered out after being pressurized and filtered, and enters the material transfer area 172, so as to form a circulation. Because the fresh air supply pipe 240 continuously delivers fresh air into the third return air passageways 180, a pressure value in the material storage and transfer area 170 is higher than a surrounding pressure value, which ensures a requirement that a pressure value in a strict cleanliness level area should be higher than a pressure value of a poor cleanliness level area. That is, because a pressure in the material storage and transfer area 170 is high, air in the space may enter the surrounding environment through gaps between the structures, and because air with a poor cleanliness level in the surrounding environment may not flow reversely, the strict cleanliness level in the material storage and transfer area is ensured.
  • Or, a partition board with a certain height may be vertically disposed downwards at a position, corresponding to each partition wall board, in the lower technical interlayer and attached to a lower bottom face of the waffle board, and a sealing plate is horizontally disposed at a lower end of each partition board. The vertically disposed partition boards and the horizontally disposed sealing plates are configured to separate the bottom of the material storage and transfer area from the outside, so as to form an independent air circulation between the material storage and transfer area and the return air passageway.
  • As may be seen from the above description, in the embodiment of the present disclosure, by arranging the partition wall boards and forming the third return air passageways, communicating with the upper technical interlayer and the material transfer area, between the partition wall boards and the material storage racks, an air circulation path in a workshop body is optimized, an air supply volume in the process production areas and the quantity of the dry cooling coils and the fan filter units is reduced, a space occupied by technical passageways and the upper technical interlayer is reduced, and energy consumption and construction costs are reduced. In addition, the fresh air supply pipe may further be arranged to provide fresh air for the third return air passageways, the sealing plate is disposed at the bottom of the waffle board corresponding to the material storage and transfer area and the third return air passageways, or the cover plate is disposed at the tops of the holes in the waffle board corresponding to the material storage and transfer area and the third return air passageways, or the partition boards with the certain height may be vertically disposed downwards at corresponding areas of the material storage and transfer area and the third return air passageways and are attached to the lower bottom face of the waffle board, and the sealing plates are horizontally disposed at the lower ends of the partition boards, so that the material storage and transfer area and the third return air passageways are separated from the surrounding environment, which further ensures the pressure, temperature and humidity requirements in the material storage and transfer area.
  • In view of a humidity change in a production environment or different requirements for the relative humidity in the production environment, in the related art, for rooms with obvious changes in relative humidity or high relative humidity requirements, under the condition that the indoor air humidity is not increased (i.e., the indoor air humidity remains unchanged), only a measure of lowering a temperature value in the clean room is adopted to increase the relative humidity so as to approach indoor temperature and humidity demand values. However, after the implementation of this measure, there may always be a certain deviation between the indoor temperature and humidity values and production demanded temperature and humidity values, which has a certain impact on the production environment, and is prone to causing the product yield to decrease.
  • In view of this, in an embodiment, please refer to Fig. 4, where humidification apparatuses are disposed in the upper technical interlayer 100 of the clean room. The clean room with a secondary humidification system provided by the embodiment of the present disclosure includes: at least one group of secondary humidification system. Each group of secondary humidification system includes: a humidification apparatus 280, disposed in the upper technical interlayer 100 of the clean room, the lower technical interlayer 110 of the clean room, the first return air passageway of the clean room, the second return air passageway of the clean room or the clean room; a relative humidity sensor 290, configured to detect the air humidity in the clean room; and a humidity controller 300 connected with the relative humidity sensor 290 and the humidification apparatus 280. The humidity controllers 300 are configured to receive a humidity signal of the relative humidity sensors 290 so as to control the humidification apparatuses 280 to operate according to the humidity signal.
  • In the above clean room with the secondary humidification system, at least one group of secondary humidification system is disposed in the clean room, and each group of secondary humidification system includes: the relative humidity sensor disposed in the clean room and configured to detect the indoor air humidity. The relative humidity sensors may be disposed in the production areas of the clean room. The production areas are places where production devices are placed. The humidity in the production areas may be detected by the relative humidity sensors disposed in the production areas, that is, the relative humidity of the production environment for a product is detected, so that the actual relative humidity of a manufacturing environment of the product may be more accurately determined. In addition, the humidification apparatuses are configured to directly humidify indoor air. The humidification apparatuses may be disposed in the upper technical interlayer of the clean room, or in the lower technical interlayer of the clean room, or in the first return air passageway or the second return air passageway of the clean room, or in the production area of the clean room. Humidified air may enter an air system in the clean room, so as to humidify the entire environment of the clean room. Of course, the humidified air may enter the production area during the circulation of the air system in the clean room, so that the production environment in the clean room gets an effect of secondary humidification. The humidity controllers are in signal connection with the relative humidity sensors, are electrically connected with the humidification apparatuses, and may receive the humidity signal detected by the relative humidity sensors and control the humidification apparatuses through the humidity signal. The humidity signal is a relative humidity value of the clean production area, and a preset value is set according to a requirement of the product produced in the production area for the relative humidity of the production area. When the relative humidity sensors detect out that the humidity value in the clean production area is less than the preset value, the humidity controllers control the humidification apparatuses to operate to humidify the indoor air, and the humidification amount may be regulated in proportion. When the relative humidity sensors detect out that the humidity value in the production area is greater than or equal to the preset value, the humidity controllers control the humidification apparatuses to reduce the humidification amount in proportion to constant and continuous humidification or does not start working. Therefore, the humidity controller control the humidification apparatuses to automatically humidify the indoor air by receiving the humidity signal from the relative humidity sensors, so as to meet the humidity requirements of the production environment in the production area, and the relative humidity of the production environment in the production area may reach the best value.
  • Therefore, in the above clean room with the secondary humidification system, a secondary humidification system is disposed in the clean room, which can effectively perform secondary humidification on the indoor air, and can increase the relative humidity of the environment in the production area, so that the relative humidity of the production environment of the product reaches the optimal value, which is conducive to ensuring a good production process and manufacturing environment, and improving the product yield.
  • In the embodiment of the present disclosure, in the above clean room with the secondary humidification systems, each group of secondary humidification system is internally provided with one or more relative humidity sensors. When there is one relative humidity sensor in each group of secondary humidification system, the humidity signal is an induction value of the relative humidity sensor; and when there are a plurality of relative humidity sensors in each group of secondary humidification system, the humidity signal is an average value of humidity induction values of the plurality of relative humidity sensors. The plurality of relative humidity sensors are provided, the average value of the induction values of the plurality of relative humidity sensors serves as the humidity signal, and the indoor relative humidity can be more accurately tested, which is beneficial to improving the accuracy of the secondary humidification systems for indoor humidification, and ensuring that the humidity of the indoor environment is the optimal relative humidity value of production.
  • It should be noted that, referring to Figs. 4-6, the clean room with the secondary humidification systems may be internally provided with a plurality of groups of secondary humidification systems, which is beneficial to improving the humidification rate of the production environment in the clean room, and making the environment humidity reach the relative humidity value required by the production environment more quickly. The humidification apparatuses 280 in the plurality of groups of secondary humidification systems may be disposed at any one, or two, or three, or four of the upper technical interlayer 100 of the clean room, the lower technical interlayer 110 of the clean room, the first return air passageway 130 of the clean room, the second return air passageway 140 of the clean room, or the clean room 120. For example, the humidification apparatuses 280 in the plurality of groups of secondary humidification systems may all be disposed in the upper technical interlayer 100 of the clean room, or the return air passageways of the clean room, or the lower technical interlayer 110 of the clean room, or the clean room 120. In addition, part of the humidification apparatuses in the plurality of groups of humidification systems may be disposed in the upper technical interlayer 100, while another part of them may be disposed in the first return air passageway 130 and the second return air passageway 140. Or, part of the humidification apparatuses in the plurality of groups of humidification systems are disposed in the lower technical interlayer 110, while another part of them are disposed in the first return air passageway 130 and the second return air passageway 140. Or, part of the humidification apparatuses in the plurality of groups of humidification systems are disposed in the upper technical interlayer 100, while another part of them are disposed in the lower technical interlayer 110. Or, part of the humidification apparatuses in the plurality of groups of humidification systems are disposed in the first return air passageway 130 and the second return air passageway 140, while another part of them are disposed in the clean room 120. Or, part of the humidification apparatuses in the plurality of groups of humidification systems are disposed in the upper technical interlayer 100, while another part of them are disposed in the lower technical interlayer 110, and while further another part of them are disposed in the first return air passageway 130 and the second return air passageway 140, that is, the upper technical interlayer 100, the lower technical interlayer 110, the first return air passageway 130 and the second return air passageway 140 are all internally provided with the humidification apparatuses. There are a plurality of ways to arrange the humidification apparatuses in the secondary humidification systems in the upper technical interlayer 100, the lower technical interlayer 120, the first return air passageway 130, the second return air passageway 140 and the clean room 120, which are not listed here. It should be noted that the setting of each group of secondary humidification system in the plurality of groups of secondary humidification systems may be made according to actual needs, and the quantity of the secondary humidification systems may also be set according to indoor needs, which are not limited in the embodiment.
  • In addition, referring to Figs. 19 and 10, since the requirements for the production environment are also different due to different products, different production processes and the like in a production workshop of display elements, which are mainstream products of the electronic industry, the requirements for the production environment are also different, the production workshop may be internally divided into a plurality of independent partitions within the production workshop according to the requirements for the production environment, special requirements for a preparation process, and the like. Products with different environment requirements are prepared or process manufacturing is conducted in the different independent partitions. The clean room may be internally provided with a first independent partition and a second independent partition according to different humidities, that is, the plurality of independent partitions include the first independent partition and the second independent partition. There may be a plurality of first independent partitions, there may also be a plurality of second independent partitions, and the quantity and layout of the first independent partitions and the second independent partitions may be set according to actual demands. Moreover, by arranging the first independent partition and the second independent partition in the clean room, there are also a plurality of options as below to set the secondary humidification systems.
  • Manner 1
  • Referring to Figs. 7-9, a first independent partition 320 and a second independent partition 330 are disposed in the clean room, and a partition wall component is disposed between the first independent partition 320 and the second independent partition 330 to separate the clean room 120 into the first clean production area 121 and a second clean production area 122, to separate the upper technical interlayer 100 into a first upper technical interlayer 101 and a second upper technical interlayer 102, and to separate the lower technical interlayer 110 into a first lower technical interlayer 111 and a second lower technical interlayer 112. The first independent partition 320 includes the first upper technical interlayer 101, the first clean production area 121, the first lower technical interlayer 111 and the first return air passageway 130. The first return air passageway 130 is located on a side, facing away from the second independent partition 330, of the first independent partition 320. The second independent partition 330 includes the second upper technical interlayer 102, the second clean production area 122, the second lower technical interlayer 112 and the second return air passageway 140. The secondary humidification systems are arranged in the first independent partition 320, and may directly humidify air in the first independent partition, which effectively improves the indoor air humidity, especially the first independent partition, and is beneficial to ensuring that the relative humidity in the first independent partition is the optimal value required by production. There may be one group of secondary humidification system, or a plurality of groups of secondary humidification systems in the first independent partition, which is not limited in this embodiment.
  • For the arrangement of the first independent partition and the second independent partition in the clean room of Manner 1, there may also be a plurality of arrangement options as below.
  • Manner 1 to arrange the independent partitions
  • Referring to Fig. 16, the partition wall component includes a partition wall 350 disposed between the first independent partition 320 and the second independent partition 330, that is, only one partition wall 350 is disposed between the first independent partition 320 and the second independent partition 330. The partition wall 350 corresponds to at least the first clean production area 121 and the second clean production area 122, and separates the first clean production area 121 from the second clean production area 122, that is, the first clean production area and the second clean production area are adjacent and next to each other, and are separated only by the partition wall.
  • The partition wall may only correspond to the first clean production area and the second clean production area, that is, the first upper technical interlayer and the second upper technical interlayer may communicate, and the first lower technical interlayer and the second lower technical interlayer may also communicate. In addition, a bottom of the partition wall may also be arranged to extend to a bottom plate of the lower technical interlayer and be in sealed fit with the bottom plate of the lower technical interlayer, that is, the first lower technical interlayer and the second lower technical interlayer are separated by the partition wall. Besides, as shown in Fig. 16, the bottom of the partition wall 350 may further be arranged to extend to the bottom plate of the lower technical interlayer and be in sealed fit with the bottom plate of the lower technical interlayer, at the same time, a top of the partition wall extends to a top plate of the upper technical interlayer and is in sealed fit with the top plate of the upper technical interlayer, that is, the first lower technical interlayer 111 and the second lower technical interlayer 112 are separated by the partition wall, and at the same time, the first upper technical interlayer 101 and the second upper technical interlayer 102 are also separated by the partition wall. In this way, the two independent partitions are completely separated, and by arranging the first independent partition and the second independent partition as independent spaces that do not communicate with each other, mutual environmental conditions may be prevented from affecting each other, which is more beneficial to ensuring respective environmental demands.
  • In Manner 1 to arrange the independent partitions, when the first independent partition and the second independent partition are arranged, by the partition wall, as the independent spaces that do not communicate with each other, the mutual environmental conditions may be prevented from affecting each other, which is more beneficial to ensuring respective environmental demands. Since the first independent partition is internally provided with the secondary humidification systems, a production process with high relative humidity requirements may be performed in the first independent partition, or products with high relative humidity requirements may be produced in the first independent partition. The secondary humidification systems may increase a relative humidity value of the air in the first independent partition, so as to ensure that the relative humidity of the air in the first independent partition reaches the optimal demand value for product production, which is beneficial to improving the product yield.
  • Manner 2 to arrange the independent partitions
  • Referring to Figs. 5-9, the partition wall component includes two side-by-side partition walls, namely a first partition wall 590 and a second partition wall 600, disposed between the first independent partition 320 and the second independent partition 330, that is, the side-by-side and opposite first partition wall 590 and second partition wall 600 are disposed between the first independent partition 320 and the second independent partition 330. The two partition walls at least correspond to the first clean production area 121 and the second clean production area 122, and separate the first clean production area 121 from the second clean production area 122. The first partition wall 590 is located in the first independent partition 320, the second partition wall 600 is located in the second independent partition 330, and a fourth return air passageway is formed between the first partition wall 590 and the second partition wall 600. The first partition wall and the second partition wall may only correspond to the first clean production area and the second clean production area, the first upper technical interlayer communicates with the second upper technical interlayer, and the first lower technical interlayer communicates with the second lower technical interlayer. In addition, a bottom of the first partition wall may further be arranged to extend to the lower technical interlayer, and a bottom of the second partition wall may be arranged to extend to the lower technical interlayer.
  • Manner 3 to arrange the independent partitions
  • Referring to Figs. 13, 14 and 15, in order to improve the accuracy of environmental requirements in each independent partition, the independent partitions may be completely separated into two independent spaces that do not communicate with each other. The partition wall component includes three side-by-side partition walls, namely the first partition wall 590, the second partition wall 600, and a third partition wall 610, between the first independent partition 320 and the second independent partition 330. The third partition wall 610 is located between the first partition wall 590 and the second partition wall 600. The first partition wall 590 is located in the first independent partition 320, and the second partition wall 600 is located in the second independent partition 330. A top of the third partition wall 610 extends to the top plate of the upper technical interlayer and is in sealed fit with the top plate of the upper technical interlayer, and a bottom of the third partition wall 610 extends to the bottom plate of the lower technical interlayer and is in sealed fit with the bottom plate of the lower technical interlayer. By separating the first independent partition 320 and the second independent partition 330 into the two independent spaces that do not communicate with each other, the mutual environmental conditions may be prevented from affecting each other, which is more beneficial to ensuring respective environmental demands. The first partition wall corresponds to the first clean production area, and the bottom of the first partition wall extends to the lower technical interlayer. The second partition wall corresponds to the second clean production area, and the bottom of the second partition wall extends to the lower technical interlayer. A fifth return air passageway 360 is formed between the first partition wall 590 and the third partition wall 610, or, a sixth return air passageway 370 is formed between the second partition wall 600 and the third partition wall 610. Or, the fifth return air passageway 360 is formed between the first partition wall 590 and the third partition wall 610, and at the same time, the sixth return air passageway 370 is formed between the second partition wall 600 and the third partition wall 610.
  • In the third manner to arrange the independent partitions, by arranging the first independent partition and the second independent partition as the independent spaces that do not communicate with each other, the mutual environmental conditions may be prevented from affecting each other, which is more beneficial to ensuring respective environmental demands. The first independent partition is internally provided with the secondary humidification systems, so that the production process with high relative humidity requirements may be performed in the first independent partition, or products with high relative humidity requirements may be produced in the first independent partition. The secondary humidification systems may increase the relative humidity value of the air in the first independent partition, so as to ensure that the relative humidity of the air in the first independent partition reaches the optimal demand value for product production, which is beneficial to improving the product yield.
  • As shown in Fig. 12, when the fifth return air passageway 360 is formed between the first partition wall 590 and the third partition wall 610, a humidification apparatus may be disposed in the fifth return air passageway 360 to facilitate humidification in the first independent partition.
  • In the embodiment of the present disclosure, in Manner 1, referring to Figs. 5, 6, 11, 12 and 16, a production device 310 that produces volatile organic compounds in the operating process is disposed in the first clean production area 11 in the first independent partition 320. The first lower technical interlayer 111 is internally provided with a zeolite runner unit 340 configured to adsorb the volatile organic compounds. The zeolite runner unit 340 may dehumidify the indoor air to a certain extent in the operating process, resulting in a decrease in the environmental humidity of the clean room, especially the first independent partition, which deviates from the environmental humidity demand value for product production. The secondary humidification systems disposed in the first independent partition 320 may directly humidify the indoor air and improve the relative humidity of the indoor air, which is beneficial to ensuring that the relative humidity of the indoor air is maintained at the optimal humidity demand value for product production, and is beneficial to ensuring the product yield.
  • Manner 2
  • As shown in Fig. 4, the first independent partition 320 and the second independent partition 330 are disposed in the clean room, and the partition wall component is disposed between the first independent partition 320 and the second independent partition 330 to separate the production area into the first clean production area 121 and the second clean production area 122, to separate the upper technical interlayer 100 into the first upper technical interlayer 101 and the second upper technical interlayer 102, and to separate the lower technical interlayer 110 into the first lower technical interlayer 111 and the second lower technical interlayer 112. The first independent partition 320 includes the first upper technical interlayer 101, the first clean production area 121, the first lower technical interlayer 111 and the first return air passageway 130. The second independent partition 330 includes the second upper technical interlayer 102, the second clean production area 122, the second lower technical interlayer 112 and the second return air passageway 140. There are at least two groups of secondary humidification systems, and the first independent partition 320 and the second independent partition 330 are both internally provided with the secondary humidification systems.
