Description

Prediction Eviction Induction System and Method for Toxic Gas Discharge Plants

FIELD OF THE INVENTION The present invention relates to a toxic gas discharge installation, and more particularly to a human safety device of a toxic gas discharge facility.

Equipment that emits toxic gases as needed in confined spaces is widely installed in the industry, and workers are unable to evacuate before the toxic gas is released or enter the workplace before being ventilated after the toxic gas is released. The case is endless.

Such gas discharge facilities are typically gas-based automatic fire extinguishing facilities. Gas-based automatic fire extinguishing systems release large amounts of non-combustible gases (eg, extinguishing agents such as carbon dioxide gas, nitrogen gas, and halon gas) at once to reduce the concentration of oxygen in the air or to absorb heat while interrupting the combustion reaction. It is a facility to suppress the.

Gas-based automatic fire extinguishing equipment can minimize secondary damage compared to water-based fire extinguishing equipment used for water, and is highly adaptable to electric fires, so it can be used for automobile-related facilities, factories, power plants, computer rooms, communication facilities, museums, and exhibition facilities. It is widely installed in libraries.

However, gas-based automatic fire extinguishing systems have potential safety problems in that most extinguishing gases have a high risk of asphyxiation or poisoning. Indeed, accidental or malfunctioning emissions of digestive gases continue to injure the lives of victims who are suffocated by victims who have not been able to understand the situation or evacuated for other reasons. Carbon dioxide gas is particularly dangerous because it can cause difficulty breathing and vomiting even at low concentrations of 5% to 10%, blindness and loss of consciousness, and central nerve palsy and death within 20 minutes. . In addition, it can be fatal at the moment of release due to the noise, cold and dry ice white clouds from tremendous pressure, and it is colorless and odorless even at high concentrations after decades of release.

Currently, gas-based automatic fire extinguishing equipment such as carbon dioxide is operated according to the related laws such as "Receiver Type Approval and Technical Standard for Product Inspection". It should have control function such as release or delay of extinguishing agent, etc. However, delay time of drug release should be within 30 seconds after sounding alarm, and the device that can adjust delay time can be easily identified. Should be. " "In each protected area, an indicator indicating the operation of the acoustic alarm system and the operation of the detector, and an alarm device such as a bell and a buzzer operating in conjunction with it, shall be attached. Can also be used. " "In a manual starter, a switch shall be fitted to indicate the switch and its operation." "There should be a light indicator indicating the release of the extinguishing agent." It is designed according to such regulations.

However, acoustic alarms are usually part of the automated re-detection system, which focuses on general fire alarms that do not know where they occur, rather than warnings of drug releases that will soon occur at a particular location, allowing workers at specific locations to escape. You may not notice the urgency of about 30 seconds as the delay time. The light source alarm device has many blind spots and it is difficult for the operator to pay attention unless the light source alarm device is looked in a direction.

On the other hand, according to the Fire Safety Standards (NFSC 106) of the carbon dioxide fire extinguishing system, the fire extinguishing system should be designed and arranged to emit all the extinguishing agent storage within 1 minute in the global discharge mode and 30 seconds in the local discharge mode. In addition, the standard specifies that automatic openings should be provided for openings or vents, and that the openings must be closed before the release of carbon dioxide.

Therefore, once a fire extinguishing agent is released, it is virtually impossible to prevent the loss of lives of personnel who have not been evacuated before.

Thus, there is a need for means to evacuate personnel before gas release in a toxic gas release facility and to recognize the presence of toxic gases in the unvented state after gas release.

The problem to be solved by the present invention is to provide a system and method for pre-emission of the toxic gas discharge facility.

The problem to be solved by the present invention is the prior eviction of the toxic gas discharge facility that can induce spontaneous eviction to the personnel staying in the toxic gas discharge area by releasing malodorant first before toxic gas discharge in the toxic gas discharge facility It is to provide an induction system and method.

The problem to be solved by the present invention is a pre-emission induction system that can induce voluntary eviction in the person remaining in the toxic gas emission scheduled area by generating a odorant and sound or mist at the same time before releasing the toxic gas in the toxic gas discharge facility And providing a method.

The problem to be solved by the present invention is to provide a preliminary eviction induction system and method of the gas-based automatic fire extinguishing equipment.

The problem to be solved by the present invention is to provide a pre-eviction induction warning device and method that can induce voluntary eviction in personnel staying in the area to be extinguished gas by releasing the odorant first before the extinguishing gas in the gas-based automatic fire extinguishing equipment It's there.

The problem to be solved by the present invention is a preliminary eviction that can induce voluntary eviction in the personnel staying in the area to be extinguished by discharging the odorant before the discharge of the gas in the gas-based automatic fire extinguishing equipment and at the same time by generating a sound or mist It is to provide an induction system and method.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention. The same reference numerals are used for the same elements in the drawings, and duplicate descriptions of the same elements are omitted.

1 is a schematic diagram illustrating a pre-emission induction system of a toxic gas discharge facility according to an embodiment of the present invention.

Referring to FIG. 1, the pre-emission induction system 10 of the toxic gas discharge facility 100 includes a main control unit 11 which generates and outputs a toxic gas emission signal, and toxic gas storage containers 101 storing toxic gas. It may include a gas pressure starting unit 12 for opening the odor and odor release device 13 for releasing the odor.

Specifically, the main controller 11 generates a toxic gas emission signal based on the sensor detection signal received from the sensors 14 or the manual operation signal received from the manual operation switch 15, and generates the toxic gas emission signal. The odor release signal may be generated and output at the time, and the delayed toxic gas emission signal may be output after the toxic gas emission signal is delayed for a predetermined delay time immediately after generation.

The delay of the main control unit 11 for a predetermined delay time without immediately outputting the toxic gas emission signal is to give an evacuation time for the personnel who are staying in the workplace where the toxic gas is to be released soon.

The toxic gas storage vessels 101 store high pressure toxic gases and are typically designed to release all of the storage amount in a time of about 30 seconds to 60 seconds depending on the facility when the valve is opened. Therefore, the delay time set by the main control unit 11 is substantially the only time that personnel can evacuate.

The gas pressure starting unit 12 opens the starting gas storage container 121 in accordance with the toxic gas emission signal to open the toxic gas storage containers 101 or according to a manual start of an operator. The starting gas compressed and stored in the gas storage container 121 opens the valves of the toxic gas storage containers 101, whereby the toxic gases stored in the toxic gas storage containers 101 are stored in the work place through the pipe 102.

May be generated to generate a gas emission operation detection signal.

Typically, the gas pressure starter 12 does not need a separate electric power source because it opens the valves of the gas storage containers using the pressure of the stored gas as a power source. Conversely, without relying on an electrical power source, the gas pressure starter 12 can open the valves of the gas storage containers using the pressure of the stored gas as a power source to release the gas as necessary. However, since the main control unit 11 should be able to identify the operation result of the gas pressure starting unit 12, the pressure switch 122 supplied with power from the main control unit 11 is connected to the gas pressure starting unit 12. Can be mounted.

Using such a configuration, the gas pressure starting unit 12 uses the pressure switch 122 at an extremely early stage in which the toxic gas is released even when the toxic gas is released due to an intentional manual start of a worker or a failure or an accident.

Figure 7 is a schematic diagram illustrating a pre-discharge induction system of the gas-based automatic fire extinguishing equipment according to another embodiment of the present invention.

The pre-eviction induction system 70 of the gas-based automatic fire extinguishing system 700 is a gas for opening the fire receiving panel 71 for generating and outputting the extinguishing gas discharge signal and the extinguishing gas storage containers 701 storing the extinguishing gas. And a odor release device 73 for releasing the odor agent.

Specifically, the fire receiving panel 71 extinguishs fire based on a fire detection signal received from the fire detectors 74, a fire report signal received from the transmitter 79, or a manual operation signal received from the manual operation box 75. Generating a gas emission signal and a gas emission interlocking signal, outputting at least one of the extinguishing gas emission signal or the gas emission interlocking signal as a odorant emission signal, delaying the extinguishing gas emission signal immediately after generation for a predetermined delay time and then delaying The extinguishing gas release signal can be output.

According to an exemplary embodiment, the gas emission interlocking signal of the fire receiving panel 71 may be one of a gas emission indicator driving signal, an acoustic alarm driving signal, an automatic closing device driving signal, and a ventilation driving signal.

The delay of outputting the extinguishing gas discharge signal immediately by the fire receiving panel 71 for a predetermined delay time is to give an evacuation time for the personnel who are staying in the workplace where the extinguishing gas is to be released soon.

The extinguishing gas storage vessels 701 store extinguishing gases, including high pressure carbon dioxide gas, and are typically designed to release all of the stored amount within a time of about 30 seconds to 60 seconds depending on the facility when the valve is opened. Therefore, the delay time set in the fire receiving panel 71 is substantially the only time that personnel can evacuate.

The gas pressure starting unit 72 opens the starting gas storage container 721 according to the extinguishing gas discharge signal to open the extinguishing gas storage containers 701 or according to a manual starting of an operator.

May be generated to generate a gas emission operation detection signal.

Typically, the gas pressure starter 72 does not require a separate electric power source because it opens the valves of the gas storage containers using the pressure of the stored gas as a power source. Conversely, without relying on an electrical power source, the gas pressure starter 72 can release the gas as needed by opening the valves of the gas storage containers using the pressure of the stored gas as a power source. However, since the fire receiving panel 71 should be able to identify the operation result of the gas pressure starting unit 72, the pressure switch 722 supplied with power from the fire receiving panel 71 is connected to the gas pressure starting unit 72. Can be mounted.

Using this configuration, the gas pressure starting unit 72 uses the pressure switch 722 at an extremely early stage in which the extinguishing gas is discharged even when the extinguishing gas is released due to an intentional manual starting of a worker or a failure or an accident.

However, this gas smell warning device releases the odorant together with the extinguishing gas, so the effect of the olfactory warning cannot be expected before the gas is released, but only as a smell of the odorant to personnel entering the fire zone after the release of the digestive gas is completed. It can only warn of the presence of extinguishing gas afterwards.

In addition, this conventional gas smell warning device requires the additional work of cutting out the gas discharge pipe and inserting the odor storage container.

On the other hand, the pre-eviction induction system 70 of the gas-based automatic fire extinguishing system 700 according to an embodiment of the present invention generates a odor release signal as soon as the extinguishing gas emission signal is generated in normal operation to generate a negative pressure. By releasing and spreading the odor, the strong odor of the odorant spread in the workplace can cause workers to find more fresh air and escape immediately without further progress, and to forcibly remove personnel remaining in the workplace before the release of digestive gas. Can be.
