[0024] As Figure 1 shown, the present invention provides a shelter for chemical production and storage sites, which includes: A shelter body 1, which is arranged at the edge of the production area and / or in an independent building; A detection and monitoring system, which includes a toxic and harmful gas detection module and / or a fire detection module. The detection and monitoring system is arranged outside the shelter body and is used to transmit a danger signal to the automatic control system when a danger signal is detected; A positive pressure air supply system, which is arranged outside the shelter body and is connected to the inside of the shelter body. The positive pressure air supply system is used to maintain the air pressure inside the shelter body higher than the outside air pressure; and an automatic control system, which is used to control the start of the positive pressure air supply system when receiving a danger signal.

[0025] In the shelter for chemical production and storage sites according to the embodiments of the present invention, it can effectively meet the need for on-site personnel to take shelter nearby in case of an accident, and at the same time ensure the safety of personnel taking shelter on the spot and preventing poisoning under conditions of explosion, high temperature, and highly toxic smoke.

[0026] The shelter body 1 is built of reinforced concrete to meet the explosion-proof and fire-proof requirements of the shelter. An anti-high-temperature and fire-resistant heat insulation layer is arranged on the outer side of the shelter body 1 to reduce the influence of high temperature on the shelter.

[0027] Manual and electric operation switches are respectively arranged on both sides of the automatic gas-proof and explosion-proof door 8 and the electric gas-proof and explosion-proof door 9.

[0028] In some specific embodiments, the positive pressure air supply system includes a fan 4, an air duct 5, a positive pressure air valve 6, and an automatic exhaust valve 7. The fan 4 is connected to the inlet end of the air duct 5, the positive pressure air valve 6 is connected to the outlet end of the air duct 5, and the automatic exhaust valve 7 is arranged inside the shelter body 1 and is communicated with the external environment.

[0029] The positive pressure air valve 6 is installed at the outlet end of the air duct 5, which can ensure that the air pressure inside the shelter is always higher than the external environmental air pressure. This positive pressure environment can effectively prevent external toxic gases, smoke or dust from entering the shelter through gaps or openings, providing a safe breathing environment for personnel.

[0030] The automatic exhaust valve 7 is arranged inside the shelter and is connected to the external environment through the air duct 5. When the internal air pressure exceeds the set threshold, the automatic exhaust valve 7 will open to discharge the excess gas, ensuring that the internal air pressure is stable within a safe range and avoiding discomfort to personnel or damage to equipment caused by excessive air pressure.

[0031] Based on the above embodiments, an automatic gas-proof and explosion-proof door 8 is provided at the entrance of the shelter body 1, and an electric gas-proof and explosion-proof door 9 and / or a manual gas-proof and airtight door 10 are arranged inside the shelter body 1.

[0032] The automatic gas-proof and explosion-proof door 8 at the entrance of the shelter can quickly close during an accident, effectively blocking the intrusion of external explosion shock waves, toxic gases and flames, providing the first safety barrier for personnel.

[0033] The electric gas-proof and explosion-proof door 9 arranged inside can further strengthen the sealing effect after the automatic door closes, preventing toxic gases from seeping through the gaps, and at the same time having an explosion-proof function to ensure the structural integrity of the shelter under extreme conditions.

[0034] The manual gas-proof and airtight door 10, as a backup facility, can still be fully sealed through manual operation in case of power interruption or automatic system failure, ensuring the safety of the internal environment of the shelter.

[0035] Preferably, a sealing strip is provided at the door gap to ensure that toxic gases cannot penetrate into the internal space, providing a safe shelter environment for personnel.

[0036] In some specific embodiments, a plurality of emergency zones are arranged inside the shelter body 1 in sequence along the direction away from the entrance of the shelter body 1, and each emergency zone is provided with an isolation door that can be opened to enter.

[0037] The plurality of emergency zones divide the inside of the shelter into several independent spaces, and each zone can be used as an independent refuge unit. When a leakage or other dangerous situation occurs in a certain zone, the manual gas-proof and airtight door 10 can quickly close to prevent the danger from spreading to other zones, ensuring the safety of personnel in other areas.

[0038] Different emergency zones can be designed as different functional areas according to actual needs, such as a medical first aid area, a rest area, an equipment storage area, etc., to meet the diverse needs of personnel during the refuge process.

[0039] At the time of an accident, personnel can choose to enter different emergency zones according to the actual situation, flexibly allocate the shelter space, and improve the resource utilization efficiency of the shelter.

[0040] In some specific embodiments, multiple emergency zones are arranged in sequence along an n-shaped path. For the convenience of use by the shelter population or the optimization of the building structure, the emergency zones can be in a straight-line shape, a curved shape, or any other shape adapted to the building complex.

[0041] Specifically, according to the movement route of the escaping personnel, multiple emergency zones include an isolation room 19, a stripping room 20, a shower room 21, a dressing room 22, and a shelter room 23 arranged in sequence along the direction away from the entrance of the shelter body 1.

[0042] In some specific embodiments, a cleaning instrument for cleaning toxic and harmful substances is provided in the isolation room.

[0043] Specifically, an eye washer 11 is provided in the isolation room 19. Personnel can wash the toxic and harmful substances on their eyes, faces, and hands first, which can effectively reduce chemical injuries and also reduce the panic caused by being contaminated with toxic and harmful substances.

[0044] In some specific embodiments, one or more of the following are provided in the shelter room: an emergency power supply and lighting system, an emergency communication system 3, emergency medicines, protective supplies, a drinking water faucet, an eye washer 11, and a pedal shower 12. These basic supplies and facilities provide comprehensive emergency protection for personnel. They can not only quickly handle body contamination, provide basic survival support, but also enhance personal protection ability and reduce the degree of accident injuries. At the same time, the user-friendly design and flexible configuration further improve the practicability and usability of the system, providing strong support for personnel to take shelter in chemical accidents.

[0045] On the basis of the above embodiments, the positive pressure air supply system further includes a coarse filter absorber 13 and a toxic and harmful gas filter absorber 14, and the coarse filter absorber 13 and the toxic and harmful gas filter absorber 14 are connected to the fan 4. The coarse filter absorber 13 can remove most visible pollutants in the air, provide preliminarily purified air inside the shelter, and improve the air quality. The toxic and harmful gas filter absorber 14 filters and absorbs toxic and harmful substances.

[0046] In some specific embodiments, an air suction shaft 15 is further provided in the positive pressure air supply system. The air suction shaft 15 can provide a stable channel for air flow, reduce air flow disorder and pressure loss, and ensure smoother transmission of air from the coarse filter absorber 13 to the fan 4. The design of the air suction shaft 15 can extend the residence time of air in the coarse filter absorber 13, enabling the coarse filter absorber 13 to have more time to intercept large particle pollutants and improve the filtering effect.

[0047] On the basis of the above embodiments, the automatic exhaust valve 7 controls the atmospheric pressure inside the shelter body 1 to be 0.09 MPa higher than the external atmospheric pressure. When the air pressure inside the shelter is higher than the outside, the air will flow out naturally, effectively preventing external toxic gases, smoke or dust from entering the shelter through gaps or openings.

[0048] The automatic exhaust valve 7 can automatically adjust its opening and closing state according to the change of the internal air pressure. When the internal air pressure is too high, the valve will automatically open to discharge the excess gas, ensuring that the air pressure is stable within a safe range.

[0049] On the basis of the above embodiments, the toxic and harmful gas detection module 24 and the fire detection module 25 include an electrochemical sensor and / or a smoke sensor. The toxic and harmful gas detection module 24 and the fire detection module 25 are used to detect toxic and harmful gases and detect fires. Therefore, the electrochemical sensor can be used to detect toxic and harmful gases, and the smoke sensor can be used to detect fires. Once the detection of toxic and harmful gases exceeds the standard or a fire signal is detected, the signal will be transmitted to the automatic control system, and the automatic control system will start the fan 4 and other emergency measures.

[0050] On the basis of the above embodiments, emergency power supplies and lighting systems are provided in multiple emergency zones, and the automatic control system is configured to control the emergency power supplies and lighting systems to start when receiving a danger signal.

[0051] In some specific embodiments, the outside of the shelter body 1 is also connected to the municipal water supply pipe network 16. The municipal water supply pipe network 16 can provide a continuous and stable water source for the shelter, meeting the basic survival needs of personnel such as drinking water and washing water during the emergency. The municipal water supply pipe network 16 is introduced into the shelter body 1 through the water supply pipe 17, and a drinking water faucet 18 is provided at the water outlet end of the pipe, facilitating the supply of drinking water for personnel.

[0052] On the basis of the above embodiments, the isolation door of the emergency zone closest to the entrance of the shelter body 1 is an automatic door, and the automatic control system is configured to control the automatic door to open when receiving a danger signal. The automatic door can quickly open after receiving a danger signal, ensuring that personnel can enter the shelter in time and reducing delays. The automatic control system can be linked with other safety systems, such as fire alarms or gas leakage detections, to ensure automatic response in multiple dangerous situations.

[0053] In some specific embodiments, a flexible shock-absorbing structure is adopted at the connection between the foundation and the wall of the shelter body 1. The flexible shock-absorbing structure can effectively absorb and disperse the energy generated by the shock wave through its flexibility and damping performance during an explosion, reducing the impact of the explosion on the shelter structure, and can also reduce the stress concentration at the connection between the foundation and the wall, thereby reducing the risk of structural damage and improving the overall seismic performance of the shelter.

[0054] In some specific embodiments, the shelter is equipped with a real-time gas concentration monitoring screen, a camera, and a remote communication system, which is directly connected to the central control room of the chemical plant. The real-time gas concentration monitoring screen can continuously monitor the concentration of harmful gases inside and outside the shelter for 24 hours, such as hydrogen sulfide, ammonia, methane, etc., to ensure the real-time and accuracy of the data. Once the concentration of harmful gases exceeds the standard, the monitoring screen will immediately issue an alarm to remind relevant personnel to take emergency measures, effectively preventing safety accidents such as poisoning and explosion. The high-definition camera can monitor the environmental conditions inside and outside the shelter in real time, including personnel activities, equipment operation status, etc., providing intuitive on-site pictures for management personnel.

[0055] In some specific embodiments, the shelter is equipped with independent oxygen supply and / or purification facilities, specifically installed in the isolation room 19 and / or the shelter room 23. The independent oxygen supply facility can provide stable oxygen supply inside the shelter to ensure that personnel can breathe clean air in case of emergency. The purification facility can filter out toxic gases and particulate matters in the air, such as hydrogen sulfide, carbon monoxide, formaldehyde, etc., to ensure that the air quality inside the shelter meets safety standards.

[0056] A specific application of this application is: When the sensor detects that the concentration of toxic and harmful gases exceeds the standard or detects a fire signal, it transmits the signal to the automatic control system, and the automatic control system starts the fan 4; After the air is absorbed by the coarse filter absorber 13 to remove dust and the toxic and harmful gas filter absorber 14 to filter and absorb toxic and harmful substances, it is pressurized by the fan 4 and conveyed into the five rooms inside the shelter through the air duct 5 and the positive pressure air valve 6; The air pressure inside the shelter is controlled by the automatic exhaust valve 7 to always be 0.09 MPa higher than the external atmospheric pressure, preventing toxic and harmful gases and flames from entering the shelter; The automatic control system starts the emergency power supply system 2 to provide explosion-proof lighting inside the shelter; The automatic control system opens the automatic gas-proof and explosion-proof door 8. After personnel enter the isolation room 19 of the shelter through the automatic gas-proof and explosion-proof door 8, the automatic gas-proof and explosion-proof door 8 is closed to prevent the explosion shock wave and toxic and harmful substances from harming the human body; When personnel are contaminated with toxic and harmful substances, an eye washer 11 is provided in the isolation room 19, and personnel first wash off the toxic and harmful substances on their eyes, face and hands; After personnel enter the stripping room 20 from the isolation room 19 through the electric gas-proof and explosion-proof door 9, the electric gas-proof and explosion-proof door 9 is closed to further prevent the explosion shock wave and toxic and harmful substances from harming the human body. When personnel are contaminated with toxic and harmful substances, they can take off all their clothes in the stripping room 20 to prevent the toxic and harmful substances on the clothes from continuing to harm personnel; After entering the shower room through the manual gas-proof airtight door 10, close the manual gas-proof airtight door 10 to cut off the diffusion path of toxic and harmful substances in the shelter. Personnel use the pedal shower 12 in the shower room to thoroughly clean their bodies and minimize the chemical harm of toxic and harmful substances. After cleaning, personnel enter the dressing room 22 through the manual gas-proof airtight door 10 and then close the manual gas-proof airtight door 10 to continue cutting off the diffusion path of toxic and harmful substances in the shelter. Personnel change into the pre-prepared clothes in the dressing room 22, enter the shelter through the manual gas-proof airtight door 10, and then close the manual gas-proof airtight door 10 to further cut off the diffusion path of toxic and harmful substances in the shelter. After finishing washing and changing clothes, personnel can supplement drinking water as needed, take protective drugs, contact the outside world through the emergency communication system 3, wait for the arrival of rescue personnel, and monitor toxic and harmful gases in real time to judge the air pollution situation in the shelter. Use protective equipment when necessary to ensure safety.
