Abstract

PURPOSE:To provide a means to immediately recover volatile, poisonous kinds of oil accidently leaked from the load on tank trucks, etc., and to prevent the recurrence of such leakage. CONSTITUTION:Chemical and natural materials are formed into a mat shape 4 and covered with an outer cover 1 made of a gas impermeable aluminium foil reinforced with inflammable, etc., glass fiber. With the use of this mat volatile, poisonous kinds of oil accidentally leaked may immediately be recovered by adsorption without resorting to natural evaporation or forced-water wash and prevention of the recurrence of such leakage may also be achieved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low flash point oil type or toxic oil leaked due to a damage accident of a tank storing a volatile oil species, an operation error, or a rollover accident of a tank truck carrying a volatile oil species. The present invention relates to an adsorption flame-retardant mat that spreads on the upper surface of oil seeds and adsorbs quickly, prevents the generation of gas, and enables quick recovery.

[0002]

2. Description of the Related Art Conventionally, even if a tank truck rolls over on a highway or the like, and the volatile oil species to be loaded leaks out, quick recovery and flameproof measures cannot be taken, and the danger is magnified. There was no other way than to wait for help. In addition, there was no other way to leak a larger amount of volatile oil species at sea than by using high-pressure water to disperse and spread the leaked oil.

[0003]

That is, the adsorption flame-retardant mat of the present invention is always installed in a vehicle, a ship or a storage tank loaded with volatile oil species, and the adsorbent mat is provided in the event of a sudden leakage accident. The main feature is that the flameproof mat covered with gas impermeable and nonflammable materials is spread, absorbs oil, minimizes the generation of volatile gas, and minimizes the risk of ignition. To do.

The present invention uses natural pulp as an adsorbent, opened cotton products such as paper, anti-woolened chemical fibers made of polypropylene,
Non-combustible, flame-retardant, flame-proof, and gas-impermeable aluminum foil, which is reinforced with glass fibers, is used to cover one side with a non-woven fabric such as polyethylene. It is an object of the present invention to provide an adsorption flame-retardant mat that can adsorb volatile low flash point oil and toxic oil species, suppress volatilization, and suppress the occurrence of disasters such as ignition.

Another object of the present invention is to form a bag-shaped reservoir on the outer peripheral side edge of the mantle so that after the adsorption, the top and bottom of the mantle are turned upside down to absorb the volatile oil in an emergency. It is intended to provide an adsorption and flameproof mat capable of preventing dripping and re-leakage.

[0006]

Means for Solving the Problems That is, the adsorption and flame-retardant mat of the present invention comprises chemically synthetic or natural fibers and the like,
Woven or non-woven fabric made of chemical fiber, natural fiber, etc. is formed into an outer mat, and a series or multiple pieces are arranged in parallel or in series, and an aluminum foil cloth is used to absorb and recover volatile spilled oil quickly, volatilize and ignite. In the case of a substance that emits a toxic gas, the feature is that it can prevent poisoning.

[0007]

Next, examples of the adsorption flameproof mat of the present invention will be described in detail.

As shown in FIG. 1, a gas-impermeable aluminum foil cloth reinforced with glass fiber is used as a jacket 1, and an adsorbent 2 made of polypropylene non-woven fabric is wrapped with a polyethylene non-woven fabric 3 and has a width of 50 cm. Mats 4 each having a length of 2 m are arranged side by side in two rows and inserted along the bag-shaped accumulation portion 5 on the outer edge of the outer jacket 1. Further, in order to prevent the mat 4 from falling off, polyethylene thread-like ends are fixed by hooks 6 having hooks.

FIG. 2 shows the function of the bag-shaped reservoir 5 when the top and bottom are inverted after being adsorbed and further folded in two, and it is possible to suppress the occurrence of secondary disasters after recovery. .

[0010]

As described above, according to the present invention, the adsorption mat covered with the gas impermeable material adsorbing the volatile oil species is turned upside down and folded in half to suppress the volatilization and It has the practical benefit of preventing leakage and preventing accidents due to ignition and gas diffusion.
