Abstract

PROBLEM TO BE SOLVED: To solve problems of present safety measures for gas supply facilities, for example, propane gas facilities have alarm gas cutoff systems for disaster but are defenseless states for a fire, other high-pressure gas supply facilities have alarms alone for the gas leakage and gas cutoff systems in earthquake, and cylinder storage facilities have manually-operated deluge systems, which are insufficient for safety measures, no wonder if an accident disaster occurs, and require urgent improvement of the safety measures, and to protect a human life and a property from the dangerous gas supply facilities. SOLUTION: Secondary disaster can be avoided by changing into safety circuits of disaster prevention systems No.1, No.2, and No.3. If a disaster prevention center is established, it can control the terminal gas supply facilities and monitor the facilities by a 24-hour system, which is a good method for the safety measures.

Description

Detailed Description of the Invention

This disaster prevention system is a system for switching the gas supply facility to a disaster prevention facility by an operation signal from a disaster prevention command operation panel in response to a signal from each disaster sensor to the high pressure gas supply facility.

BACKGROUND OF THE INVENTION A conventional disaster prevention system is a system for issuing a disaster warning by stopping gas supply in the event of a disaster, but the system of the invention operates a sprinkler of a cylinder storage box by a disaster sensor or in a facility. Shall be degassed or degassed according to the nature of the gas through a detoxification device and a gas recovery device, or a replacement gas shall be sent into the device to prevent a secondary disaster even if the device is destroyed. .

[0002]

2. Description of the Related Art Conventionally, when a disaster occurs, a warning is given by each sensor and a gas supply is stopped.

[0003]

[Problems to be Solved by the Invention] When dangerous gas is eliminated in the gas supply equipment, and in the case of combustible gas, non-combustible (substitution) gas is passed to prevent fire and prevent secondary disasters even if destroyed. You can

[0004]

[Means for Solving the Problems]

In the case of a combustible gas supply facility, a sprinkler is operated in the cylinder storage to prevent a flame explosion due to a fire. In addition, by passing a non-flammable gas through the supply equipment, it is possible to replace the gas inside the equipment and prevent flame and explosion even if the equipment is destroyed.

[0006] In the case of a fire in the case where the combustion-supporting gas and oxygen are deficient, in the case of a fire, a sprinkler is operated in the cylinder storage box to prevent the explosion and flame of the cylinder and degas the gas supply facility to cope with a disaster. Also, when an oxygen deficiency occurs in a work place where gas is used, an alarm is issued and the gas is stopped.

In the case of a special gas (toxic gas, corrosive gas), depending on the nature of the gas, water is sprinkled for detoxification treatment in the cylinder storage box, and the gas supply equipment is shut off to remove the gas detoxification device and the gas recovery device. Use to remove gas and prepare for equipment collapse.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The system of the present invention is designed to prevent disasters by switching to three types of disaster prevention system basic type disaster prevention circuits depending on the type of gas depending on the state of the disaster.

When flammability is a nest, in the event of a disaster such as a fire, earthquake, or gas leak, the gas supply facility should be equipped with a disaster prevention system N.
o. 1 Switch to the basic circuit to deal with disasters.

In the case of burnable gas and oxygen deficiency, earthquake, gas leak, and oxygen deficiency disaster prevention system No. Switch to the basic form of 2 and activate the sprinkler in case of fire.

In case of special gas (toxic and corrosive), the disaster prevention system No. Switch to the basic type of 3 to deal with disaster prevention. When degassing the equipment, use an exclusion device or a gas recovery device.

Embodiments will be described with reference to the drawings. This system is managed by a disaster prevention center, terminals, gas supplier and network as shown in FIG.

When a disaster occurs, the disaster prevention command operation panel receives the signal from the disaster reception sensor in the terminal configuration unit of FIG. 2 and switches from the operation panel to the disaster prevention system for each alarm and gas supply facility according to the operation signal. Deal with.

Function of disaster prevention command operation panel Fig. 2, Fire sprinkler The sprinkler device in the cylinder is activated when a fire occurs near the bomb storage. Stop gas supply. gas releasing. Supply of replacement gas.

Earthquake Gas supply is stopped by the emergency shutoff valve. Degassing the supply equipment. (Substitution gas supply depending on the type of supply gas)

Gas leak Gas is shut off by the emergency shutoff valve after a gas leak alarm. gas releasing.

Gas leak (toxic gas) Gas leak alarm. Gas shutoff by emergency shutoff valve. Degas using a harm removal device or a gas recovery device. (The abatement device is set according to the nature of the gas )

Oxygen deficiency Gas cutoff after oxygen deficiency alarm. gas releasing.

Abnormal consumption Gas stop after abnormal consumption alarm.

[Effects of the Invention] Disasters such as fire, earthquake, gas leak, gas poisoning, oxygen deficiency, abnormal consumption, etc. 1, N
o. 2, No. It can be prevented by switching to the circuit of No. 3.

Disaster prevention system No. The first is a circuit dedicated to flammable gas, and by switching to this circuit, it is possible to prevent fires, earthquakes, gas leaks, and accidents of abnormal consumption.

Disaster prevention system No. 2 is used to prevent flammable gas and oxygen deficiency. By switching to this, equipment disasters can be prevented even if each disaster occurs.

Disaster prevention system No. 3 is used for special gas (toxicity, corrosiveness), and at the time of disaster, equipment disaster can be prevented by stopping the gas and treating the gas in the equipment with the abatement device and the gas recovery device.

[Brief description of drawings]

FIG. 1 Overall view of disaster prevention system configuration The terminal part of this is the invention part.

FIG. 2 is a block diagram of a terminal. In this, the application unit is a disaster prevention command operation panel and a disaster prevention system circuit.

FIG. 3 This circuit is a system for flammable gases.
Disaster prevention command The operation command of the operation panel is used to prevent the disaster caused by the equipment by stopping the sprinkling gas stop gas removal gas replacement according to the disaster.

[Fig. 4] This circuit is applied to burn gas and oxygen deficiency. In the event of a fire, the sprinkler will be activated by the automatic valve to prevent the explosive flame of the bomb storage. In the event of a disaster, the automatic valve will stop gas supply and the automatic valve will vent gas to deal with the disaster.

FIG. 5: This circuit is a system for toxic and corrosive gases. For degassing, use a detoxification device or a gas recovery device. The disaster prevention system is turned on by an operation command from the disaster prevention command operation panel.
