Description

Environmentally friendly fuel made of rubber and manufacturing method thereof

The invention relates to an environmentally friendly fuel made of rubber and a manufacturing method thereof, in particular to an inventor who can convert waste rubber material into an economical and environmentally friendly fuel.

According to the waste, the waste is divided into general waste and commercial waste. The general waste includes waste containers, waste motor vehicles, electronic appliances, waste information articles, waste tires, waste lead storage batteries, waste dry batteries, waste lighting sources, and I. Others [such as pesticides and special ring-waste containers, etc.]; common commercial wastes include sludge from water purification plants, sewage sludge, pulp and paper sludge, textile sludge, stone sludge, and waste sand. In order to avoid occupying a large amount of waste and occupying the land, the waste is usually incinerated or buried, or the waste is converted into a recyclable material through other treatments, thereby implementing the concept of environmental protection. Can promote economic development.

And because of the inventor's dedication to the concept of environmental protection, the research on the recycling of waste plastic containers, that is, an environmentally friendly fuel and its manufacturing method of the prior application, is to grind the polyurethane foam material through the grinding device; The ground polyurethane foam is placed in a stirring device, and a certain proportion of the halogen-free flame retardant is simultaneously added, and the mixture is thoroughly mixed through a stirring device to obtain a mixture; the mixture is placed in a molding device for heating and compression. The plastic molded product is placed in a granulating device and heated to emit an environmentally friendly fuel; and the environmentally-friendly fuel is cut to a predetermined length to obtain an environmentally friendly fuel that can be burned without toxicity.

Now, the inventor has studied the recycling of waste rubber. The main source of waste rubber is the tire manufacturing industry, followed by the rubber factory, the waste rubber, defective products, waste materials produced in the process, and the consumption of motor vehicles. Waste tires, etc. Tires are a kind of consumables, and they all have a loss to an unusable day. Every year, tens of millions of vehicles are driving all over the world. Therefore, every year, considerable tires are produced, and these waste tires become polluted. One of the sources of manufacturing.

The general tire composition is complex, including natural and synthetic rubber, black carbon, nylon coils, steel wire, sulfur, petroleum, resin, etc., which are mixed in the manufacturing process and molded at high temperature, basically have undergone qualitative changes and cannot be restored. Material; and the calorific value of waste tires is high (37 million joules per kilogram). In the past, the conventional cutting process used as fuel for cement kiln, power plant and paper mill, but the exhaust gas contained therein contained carcinogens such as dioxin and nitrogen oxides. Particles and foul odors, slag also has a large amount of ash, and the overall resource utilization benefits should be re-evaluated.

In addition, waste tires, plastics, and rubber are treated by cracking to refine raw oil. In the cracking process, carbon black is produced, but there is no way to properly reuse carbon black. However, because carbon black is rich in carbon, some manufacturers will sell the produced carbon black to his factory for use as coal, but because of the high cost of cracking, if it is simply sold, it will be for carbon black manufacturers. It is not worthwhile to say.

The reason is that the inventor has been carrying out research and development and practical production experience of the relevant industries for many years, and has researched and improved the existing structure to provide an environmentally friendly fuel made of rubber and its manufacturing method, in order to achieve better practical value.

First, the practical application techniques and means of the present invention, as shown in the first figure, are schematic diagrams of the substrate of the environmentally friendly fuel of the present invention, wherein:

The main purpose is to use the discarded rubber material (1), after the rubber material (1) is minced into fine powder, and then add a quantitative proportion of the detoxifying substance (2) and thoroughly mix, so that the detoxifying substance (2) The chemical reaction removes harmful chlorine and sulfur substances in the rubber material (1), so that an environmentally friendly fuel (3) which is combustible and non-toxic can be obtained.

Generally, the burning value of rubber material is too high, about 7900kal/kg, which will damage the boiler and produce harmful chlorine gas. When a certain proportion of detoxifying substances (2) are added to the rubber material (1), the detoxifying substance (2) It mainly contains a halogen-free flame retardant (21) and a desulfurizing agent (22). After adding a halogen-free flame retardant (21) [flammable agent], the rubber material (1) can be combined with external gas during combustion. The ignition value is controlled at about 6000-6800kal/kg, thereby reducing the generation of harmful chlorine substances. The addition of the desulfurizing agent (22) mainly removes the sulfur in the waste rubber molecule by chemical reaction, and then captures it by another substance, and precipitates into a non-flammable, non-polluting substance to make the rubber material (1) It is a high-quality regenerative non-toxic environmentally friendly fuel that does not release sulfur oxides during combustion. An example of a desulfurizing agent is as follows:

The reaction of 1,4-Benzoquinone with Benzoic acid produces a phenyl radical, which is scavenged by phenyl radicals to remove sulfur from the rubber molecule, and then calcium-based materials such as CaO. The trapping sulfur S molecules such as CaCO ₃ and CaC form precipitates such as CaS and CaSO ₄ which are harmless and non-flammable.

However, if the addition ratio of the halogen-free flame retardant (21) is too high, the rubber material (1) cannot be burned. Therefore, the addition ratio is appropriately controlled, and the present invention obtains an optimum addition ratio through experiments, and the detoxification substance (2) The weight percentage added to the rubber material (1) is 5 to 35%, and wherein the halogen-free flame retardant (21) is quantified in a weight percentage of 1.5 to 17.5%, and the desulfurizing agent (22) is quantified. The weight percentage is between 2.5 and 24.50%; further, the ratio of the halogen-free flame retardant (21) to the desulfurizing agent (22) is controlled to be between 30 and 50%: 50 to 70%.

Further, the above-mentioned environmentally-friendly fuel can be heated and pressurized and shaped into a solid environmentally friendly fuel; when the rubber materials are not adhered to each other, a detoxifying substance is added to the ground rubber material, and the weight percentage can be further added 2 ~6% of the adhesive [the adhesive is made of water-based resin], and then heated, pressurized, and molded to obtain a solid-type environmentally friendly fuel that can be burned without toxicity.

The mixture is thoroughly mixed by the stirring device to obtain a mixture; further, the stirring device may be a ball type mixer or the like. However, the obtained mixture can be used as a powdery environmentally friendly fuel (3).
