Description

Technical Field

[0001] The utility model relates to the technical field of reactor isolation cabins, in particular to a modular integrated clean isolation cabin for installing a reactor. Background Art

[0002] The purpose of reactor installation cleanliness assurance is to prevent harmful substances (such as ferrite, hard particles, etc.) from entering the reactor fluid system during installation, causing core deposit activation, affecting the operation of rotating parts, component corrosion, and reduced heat exchange performance, and even affecting the safety and life of the reactor operation.

[0003] During reactor construction at large commercial nuclear power plants, the construction path and the progress of area and room handovers are generally combined with the cleanliness requirements for different equipment installations. The boundaries of the nuclear island building / room area define the corresponding work zones, establish clean work areas, and clean and control the installation activity environment. Reactor installation cleanliness control requirements are the highest, and the general requirements are as follows:

[0004] (1) Commercial nuclear power plants often use the open-top hoisting method to install reactors. During the installation, the nuclear island RX building is used as the boundary, all openings and doors are blocked, and a temporary enclosed space is established that can withstand a certain internal air pressure.

[0005] (2) The closed working area should be supplemented with filtered clean and dry air, and the filter mesh size should be 20 to 30 μm.

[0006] (3) Personnel entering the closed work area must obtain approval and go through the locker room to wear buttonless white work clothes with fully closed pockets, a hat, lint-free white gloves, and clean shoes or shoe covers before entering the closed work area.

[0007] (4) The materials used for the floor, inner walls and ceiling of the enclosed work area are not allowed to generate dust.

[0008] (5) Machining and all activities that may generate dust are strictly restricted in closed work areas. If such activities must be carried out, a temporary isolation room must be established and equipped with a dust collection system.

[0009] (6) Smoking, eating and urinating are prohibited in the enclosed work area.

[0010] (7) The floor of the enclosed work area should be kept clean at all times, and useless materials generated by special activities should be removed immediately.

[0011] (8) Take appropriate mechanical protection measures to protect the installed items from falling and being hit by heavy objects.

[0012] Currently, the installation of reactors in nuclear facilities is sometimes carried out in ordinary workshops and sometimes in open air. The cleanliness of the installation environment is difficult to control and has the following drawbacks:

[0013] (1) When installing a reactor in an ordinary factory building or open-air location, temporary clean work areas are usually built using scaffolding, curtains, etc. The construction plan needs to be temporarily designed, and the progress is strongly restricted by the handover of areas / rooms. It requires a lot of manpower and material resources, a large amount of work, and occupies a long period of time on the main line, affecting the overall construction progress of the nuclear facility.

[0014] (2) The temporary clean work area constructed with scaffolding, curtains, etc. cannot be effectively sealed at the top of the clean work area because the reactor is installed using the "open-top lifting method". This makes it difficult to control the cleanliness of the reactor installation environment and it is difficult to protect the installed items from falling and being hit by heavy objects.

[0015] (3) The environmental cleanliness of temporary clean work areas built with scaffolding, curtains, etc. mainly depends on the air purification system in the factory. Due to the large space of the factory, the configuration requirements of the purification equipment are high, the energy consumption is high, and it is not conducive to internal micro-positive pressure control.

[0016] (4) Factory air purification systems often use filtration methods, but traditional filters have limited control over ambient particulate matter, and factories generally do not have return air systems. The ambient air quality is affected by the filters and is difficult to further improve.

[0017] (5) In addition to the reactor installation personnel, a large number of construction personnel for other cross-operations in nuclear facilities also enter ordinary plant buildings. It is difficult to control and manage the personnel, which brings potential risks of foreign objects falling into the reactor installation. Utility Model Content

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] like Figure 1 As shown, in this embodiment, a modular integrated reactor installation clean isolation cabin is provided, comprising a main cabin body 1, a movable roof 2, a bearing base, an air purification device 3, an electrical control box body 4, an air shower room 5, a lighting lamp 6 and a monitoring camera 7; the main cabin body 1 is installed on the bearing base, the upper end opening of the main cabin body 1 is opened to form a hoisting port, and the movable roof 2 is correspondingly arranged horizontally on the hoisting port; the main cabin body 1 is circumferentially provided with an isolation cabin inlet and outlet communicating with the outside world, the air shower room 5 is correspondingly arranged on the outside of the isolation cabin inlet and outlet, and the outlet of the air shower room 5 is connected to the isolation cabin inlet and outlet; the air purification device 3 is connected to the inside of the main cabin body 1, the electrical control box body 4 is arranged on the inner peripheral wall of the main cabin body 1, and the lighting lamp 6 and the monitoring camera 7 are arranged on the top of the inner peripheral wall of the main cabin body 1.

[0038] In this embodiment, see Figure 2 and Figure 3 The main cabin 1 includes a main frame and a protective plate. The main frame includes a main square tube 101 and an installation frame 102. A plurality of main square tubes 101 are spliced ​​in sequence along the circumference of the installation frame 102 to form a rectangular main frame with a hollow interior and open upper and lower ends; the top, bottom and side walls of the main frame are correspondingly provided with protective plates; the main frame is set on the supporting base.

[0039] According to the selected design style, combined with the mode of transportation (water transport / land transport) and the maximum size of the hoisted items, the structure of the main cabin 1 is designed. The structural form can be single module or modular combination. The frame structure design should be able to meet the structural strength of the main cabin 1 and the load capacity of personnel (2.5KN / m 2 ) requirements as light as possible. According to the frame structure, the top, bottom (if any), and side wall protection plates of the main cabin 1 are selected. The bottom side protection plate can be selected according to the bottom structure of the main cabin 1 (for example Figure 3 ) and personnel live load (2.5KN / m 2) requirements, 3mm stainless steel plates are used, and the top and side wall protection plates are made of light color steel corrugated plates with fire-retardant coatings. The appropriate style is selected according to its section inertia moment, section resistance moment and other parameters.

[0040] Through on-site investigation and mapping of the load-bearing base style, the detailed design of the load-bearing base is carried out in combination with the analysis of the overall stress conditions of the main cabin 1. The installation connection methods include: bolt connection and welding.

[0041] In this embodiment, the main cabin body 1 is provided with windows communicating with the outside world on its circumference, and the windows are correspondingly provided with visual explosion-proof windows 9 and viewing fences 10 for personnel to observe the hoisting conditions inside the main cabin body 1 from the outside, and the viewing fence 10 is provided on the outside of the visual explosion-proof windows 9.

[0042] In this embodiment, the design of the main cabin 1 should be able to meet the technical requirements of transportation, transfer and lifting, installation item lifting, internal staff carrying, on-site installation position and interface, modular splicing, etc. In addition to meeting the structural rigidity and easy-to-clean and non-falling surface requirements, its material must also have the corresponding fire protection level requirements.

[0043] In this embodiment, considering the hoisting of the installation items, an openable and closable hoisting port is set at the corresponding position on the top of the main cabin body 1 of the clean isolation cabin to facilitate the hoisting of the equipment. A hard isolation movable ceiling 2 with dust-proof function is provided at the hoisting port, and the operation mode can be manual operation or electric operation.

[0044] In this embodiment, a sliding opening and closing roof is adopted, and the sliding opening and closing roof includes two movable panels horizontally arranged on the top of the main cabin body 1, and slide rails extending along the length direction are respectively provided on the opposite sides of the lifting port. The opposite ends of the movable panels are respectively provided with guide rails corresponding to the two slide rails. The two movable panels slide toward each other to splice and close the upper end of the main cabin body 1, or the two sliding panels slide back to back to separate and open the upper end of the main cabin body 1.

[0045] like Figure 4 As shown, in order to better prevent dust, a lifting sealing device 11 is provided on the guide rail of the movable top plate. The lifting sealing device 11 includes a lifting component and a sealing component. The lifting component can realize that the movable plate slides open when it is lifted, and the sealing component is pressed after the lifting component falls, thereby ensuring the dust-proof sealing of the gaps around the movable plate.

[0046] At the same time, the ends of the movable plates close to each other are provided with locking devices. When the two movable plates move toward each other to a suitable position, the locking devices can lock the movable plates at that position, thereby covering the lifting opening.

[0047] In this embodiment, to ensure a tight connection between the bottom of the clean isolation chamber and the reactor installation area, a first soft barrier extending downwardly is provided along its circumference. When the clean isolation chamber is located in the reactor installation area, the first soft barrier completely seals the bottom of the clean isolation chamber with the reactor installation area. The first soft barrier can be implemented in the form of a coaming, scraping cloth, thick PE film, fireproof curtain, etc., to ensure a complete enclosure of the entire reactor installation space.

[0048] In this embodiment, considering that the clean isolation cabin may be hoisted and assembled at high altitude, in order to reduce the risk of high altitude operation, a personnel high altitude operation installation / assembly operation platform can be added outside the main cabin body 1 according to the actual situation on site.

[0049] Design the lifting lugs based on the clean isolation chamber module's weight and center of gravity, taking into account the crane operator's maneuverability in installing the lifting rigging at the lugs. Pre-drill holes or prefabricate mounting / fixing brackets in the main chamber 1 based on the selected equipment and its system piping installation dimensions.

[0050] In this embodiment, the air purification equipment 3 includes a fresh air unit, an air conditioning unit and a dehumidification unit. The fresh air unit is installed on the outer wall of the main cabin body 1 and is connected to the interior of the main cabin body 1 through the air inlet pipe 8; the air conditioning unit and the dehumidification unit are installed on the inner wall of the main cabin body 1.

[0051] (1) Fresh air unit

[0052] The fresh air unit can use high-efficiency air filtration system (HEPA filter), electrostatic dust removal and other methods to continuously purify the air. The filtration accuracy of the high-efficiency filtration device should be less than 20-30μm.

[0053] Fresh air volume refers to the amount of fresh air introduced from the outside into the room per hour (m 3 / h), is an important indicator for measuring indoor air quality. The fresh air volume generally calculated by "volumetric air changes" can meet the cabin ventilation needs and reduce the number of dust particles, but this easily ignores the actual demand for oxygen by the human body. Based on the previous experience of reactor installation environment control and confined space oxygen concentration control, in order to maintain the continuous air quality in the clean isolation room and the comfort of the construction workers working inside it, it is recommended to calculate it on a per capita basis when there are many people, 50m per person. 3 / h. When there are few people, it is calculated based on the space volume, about 1.5m per cubic meter. 3 / h calculation.

[0054] Considering that the hoisting port needs to be opened when the reactor is installed and hoisted, in order to ensure a slightly positive pressure in the isolation cabin, when the hoisting port is opened, the pressure difference between the inside and outside of the clean isolation cabin can be monitored in real time to automatically control the variable frequency motor or electric valve to increase the fresh air volume and reduce the return air volume, so as to achieve the effect of a slightly positive pressure (above 10Pa) in the isolation cabin.

[0055] (2) Air conditioning unit

[0056] According to human comfort requirements, the effective temperature of the air-conditioned environment in summer should be within the range of 19℃ to 25℃, and the effective temperature of the air-conditioned environment in winter should be within the range of 16℃ to 23℃.

[0057] When selecting the air conditioner for the clean isolation cabin, the air conditioner is required to have its own constant temperature control system and a water tank with sufficient capacity to meet the daily reactor work needs.

[0058] (3) Dehumidification unit

[0059] According to human comfort requirements, the relative humidity in summer is generally 50%, and in winter it is generally 30% to 50%.

[0060] The dehumidifier can be equipped separately according to the actual situation on site, or an air conditioner with dehumidification function can be optionally equipped.

[0061] In this embodiment, single-person interlocked air showers 5 are installed at the entrance and exit of the clean isolation cabin to manage personnel entry and exit. This interlocking function ensures environmental cleanliness within the clean isolation cabin during entry and exit. Air showers 5 can be configured as either single-blowing, single-drenching or dual-blowing, dual-drenching, depending on the number of people entering and exiting the clean isolation cabin. Choosing the right air shower 5 can enhance management of personnel entering and exiting the clean work area and improve work efficiency.

[0062] A mounting platform fixedly connected to the main cabin 1 is installed at the entrance and exit of the cofferdam, and the air shower 5 is installed on this mounting platform. To ensure a tight connection between the air shower 5 and the cofferdam entrance and exit, a second soft barrier is installed between the exit of the air shower 5 and the cofferdam entrance and exit. This second soft barrier is used to ensure a tight seal between the exit of the air shower 5 and the cofferdam entrance and exit. This second soft barrier can be formed in the form of a coaming, scraping cloth, thick PE film, fireproof curtain, etc. to provide a soft isolation seal between the two to ensure a tight seal.

[0063] The air shower room 5 has its own entry and exit doors, and the double doors can be interlocked, which can play a good buffering and isolating effect, ensuring that the cleanliness of the environment in the clean isolation cabin will not be destroyed by the entry and exit of people.

[0064] In this embodiment, the style of the clean isolation cabin can be selected according to actual conditions. The fully enclosed type with a lifting port (without a bearing base) is suitable for installing items and storing in-core components; the semi-enclosed cover type with a lifting port (the bottom is completely empty and a platform needs to be set up) is suitable for the installation of reactors with large mechanical equipment in the clean isolation cabin; the semi-enclosed cover type with a lifting port (a bearing base is set up and connected to the bottom structure and the bottom of the clean isolation cabin is hollow, and a personnel walkway and a viewing fence 10 are set up around the interior, such as Figure 1 shown) are suitable for reactor installation operations.

[0065] In this embodiment, the on-site installation process of the clean isolation cabin is as follows:

[0066] (1) After the designed bearing base is installed in place, the clean isolation cabin is hoisted onto the bearing base and fixed with bolts or welding, and check whether the clean isolation cabin is firmly fixed. For the modular clean isolation cabin, the modules need to be installed and fixed in place step by step, and then spliced ​​together. Check whether each module is firmly fixed, whether each module is spliced ​​normally, and whether each connection seam has been sealed with sealing strips or tapes;

[0067] (2) Check the connection between the bottom of the clean isolation cabin and the installation area, and use fences, scraper cloth, thick PE film, fireproof curtains, etc. to seal the site to ensure that the clean area forms a closed space.

[0068] (3) The supporting equipment of the main cabin 1 (visit fence 10, air conditioning unit, fresh air unit, dehumidification unit, monitoring camera 7, lighting 6, electrical control box, industrial-grade aviation socket and air shower room 5, etc.) are installed.

[0069] (4) Large equipment such as air conditioning units, fresh air units, and dehumidification units can be installed on the ground or on the outer wall of the isolation cabin according to the actual situation on site (equipment installation brackets must be prefabricated in advance). Connect the equipment wiring and the equipment inlet and outlet ducts. Pipes that need to pass through the outer wall of the isolation cabin can be prepared in advance. After the equipment is installed, check whether the cable and air duct connections are firm and stable. If necessary, install support brackets.

[0070] (5) The wiring integrity and line damage of the clean isolation cabin need to be checked again on site.

[0071] (6) According to the installation height of the clean isolation cabin, a solid platform is set up near the entrance and exit to place the fixed air shower room 5, so that the air shower room 5 is close to the entrance and exit of the clean isolation cabin. Soft isolation measures can be used to ensure the sealing between the air shower room 5 and the clean isolation cabin.

[0072] In this embodiment, the on-site commissioning and use management of the clean isolation cabin are specifically as follows:

[0073] (1) Use an external power cord to connect an industrial-grade aviation socket to power the clean isolation cabin; connect the internal power supply of the electrical control box to power lighting, video and other equipment.

[0074] (2) Connect the external power supply of the supporting large equipment to supply power to the supporting large equipment.

[0075] (3) Operate the lifting port movable ceiling 2 to open and close, check whether there is any jamming, and whether it can be sealed and dustproof when closed.

[0076] (4) Debug the air conditioning unit, fresh air unit, and dehumidification unit, set the relevant parameters according to the instructions, and check whether the functions of each device are working properly.

[0077] (5) Check the lighting conditions of the lighting lamp 6 in the clean isolation cabin to see if there are any lighting blind spots that may affect the installation.

[0078] (6) Debug the camera's camera angle and clarity on the external monitoring display connected to the monitoring camera 7.

[0079] (7) Connect the external power supply of air shower room 5 to power the equipment, check whether its air shower function is normal according to the requirements of the instructions, whether the interlocking door function is normal, and set the blowing time of air shower room 5 to an appropriate value based on past experience (generally set the single blowing time to 10s).

[0080] (8) Turn on the fresh air unit and use a dust particle monitor to measure whether the number of dust particles at the fresh air outlet meets the requirements;

[0081] (9) When the clean isolation cabin is out of use, it should be protected and maintained regularly according to the instructions of each equipment.

[0082] By adopting the above technical solution disclosed in the utility model, the following beneficial effects are obtained:

[0083] The present utility model provides a modular integrated clean isolation cabin for reactor installation. Economically, it is movable and reusable, which can reduce repeated investment, avoid large-scale isolation space, reduce human and material investment, and can be prefabricated in advance, occupying less mainline construction period, shortening the nuclear facility construction period, and improving economic efficiency. Management: The integrated configuration of isolation, lighting, purification, environmental control, camera, and air shower room makes installation and use and daily management more convenient, and it is easy to control the entry and exit of personnel, reducing the risk of potential foreign objects falling into the reactor. Work: The use of high-efficiency filtering fresh air equipment and inlet and return air design makes the air purification level of the clean isolation cabin environment higher.
