Description

Technical Field

[0001] The invention relates to the technical field of ethylene glycol fuel, in particular to a safe fuel for hot pot. Background Art

[0002] Ethylene glycol is also known as glycol, 1,2-ethylene glycol, or EG for short. Its chemical formula is (CH2OH)2, and it is the simplest diol. Ethylene glycol is a colorless, odorless, sweet-tasting liquid with low toxicity to animals. Ethylene glycol is miscible with water and acetone, but has a low solubility in ethers. Ethylene glycol is a renewable energy source. When used as a fuel, it can reduce the waste of petroleum resources, improve unreasonable resource allocation, and protect the environment.

[0003] Moreover, it is smokeless, odorless, pollution-free, residue-free, black pot-free, clean and hygienic when burning. The carbon monoxide produced when burning is lower than that of diesel and liquefied gas, which protects the health of chefs to the greatest extent. In addition, its leakage is easy to detect and can be diluted with water. When it catches fire, it can be extinguished by pouring water. This fuel is a water-soluble liquid and is safe and reliable. Accidentally leaked ethylene glycol can also be naturally dried, and will not pollute the environment like diesel or liquefied gas, causing safety hazards.

[0004] In actual application, in order to facilitate the refilling of ethylene glycol fuel, hot pot restaurants will put ethylene glycol fuel in kettles, and then pour it into the gas appliances in portions. The kettles are usually placed in hidden locations, but the staff usually forget to take back the kettles filled with ethylene glycol in time due to their busy work. Diners may easily mistake ethylene glycol fuel for water, resulting in accidental drinking or ingestion. Due to its sweet taste, the intake of toxic fuel is increased. Summary of the invention

[0005] The purpose of the present invention is to provide a safe fuel for hot pot, so as to solve the problem mentioned in the above background technology that diners easily mistake ethylene glycol fuel for water, resulting in accidental drinking or ingestion.

[0006] The technical scheme adopted by the present invention is as follows: a safe fuel for hot pot, which is composed of raw materials in the following proportions: 84% to 94% of ethylene glycol and 0.000001% to 0.00001% of pigment.

[0007] Furthermore, the composition further comprises 0.1% to 1% of a flame retardant.

[0008] Furthermore, 5% to 15% of pure water is added to the flame retardant to prepare an aqueous solution, which is then added to ethylene glycol.

[0009] Furthermore, the bittering agent is contained in an amount of 0.001% to 0.005%.

[0010] Furthermore, the invention also includes 0.0005% to 0.001% of chemical flavor.

[0011] Furthermore, the composition further comprises a preservative in a proportion of 0.001%.

[0012] The beneficial effects of the present invention are: 1. By adding pigments to the fuel, ethylene glycol is formed into a striking color, which is different from the color of water, so that diners have a visual resistance, avoiding diners to ingest fuel without worries and avoiding the phenomenon of accidental drinking or ingestion.

[0013] 2. By adding flame retardants, after the ethylene glycol is consumed, the cotton wick will be carbonized and will not continue to burn, preventing the cotton wick from producing toxic and harmful gases.

[0014] 3. By adding pure water, the flash point of ethylene glycol liquid reaches above 300°C. If the box is accidentally knocked over, the outflowing water-containing ethylene glycol will not form a flowing fire, but only the wick will continue to burn, and no fire will be formed. The safety is greatly improved, but the combustion calorific value is basically not affected. The loss of combustion calorific value can be compensated by adjusting the height of the wick. In addition, the burning time remains unchanged.

[0015] 4. By adding bittering agents, diners will develop a resistance in terms of taste, which will prevent them from ingesting fuel without any worries and avoid the phenomenon of accidental ingestion or accidental drinking.

[0016] 5. By adding chemical flavors, diners will develop a resistance from the sense of smell, which prevents them from ingesting fuel without worry and avoids the phenomenon of accidental drinking or ingestion.

[0017] 6. By adding preservatives, the corrosion resistance of the iron box can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the present invention is further described in detail below through embodiments.

[0022] like Figure 1 and Figure 2 As shown, the existing fuel appliance includes a box body 1, which is an inverted cavity structure. A bottom cover 2 is provided at the lower end of the box body 1, a refueling port 3 is provided in the middle of the top surface of the box body 1, a top cover 4 is buckled on the refueling port 3, and a vent 5 is provided on the top cover 4; a plurality of insertion holes 6 are provided on the top surface of the box body 1, and cotton wicks 7 are inserted into the insertion holes 6.

[0023] A safe fuel for hot pot is composed of raw materials in the following proportions: 84% to 94% of ethylene glycol and 0.000001% to 0.00001% of pigment. By adding pigment into the fuel, ethylene glycol forms a striking color, which is different from the color of water, so that diners have a visual resistance, which prevents diners from taking in the fuel without worry and avoids drinking or eating by mistake.

[0024] Furthermore, the pigment is an analytically pure pigment with a content of 99%, and the color of the pigment is any one of red, yellow, blue, and black, or other colors formed by a combination of red, yellow, blue, and black.

[0025] Furthermore, considering that the cotton wick continues to burn after the ethylene glycol is consumed, producing glyoxal gas, which is a highly carcinogenic gas, 0.1% to 1% of flame retardant is also included. By adding the flame retardant, the cotton wick will be carbonized after the ethylene glycol is consumed and will not continue to burn, thereby preventing the cotton wick from producing toxic and harmful gases.

[0026] Furthermore, the flame retardant is any one of phosphate, phosphite, phosphonate, organic phosphorus salt, phosphorus heterocyclic compound, polymer phosphate and polymer phosphonate; further, considering that the above flame retardant belongs to phosphorus flame retardant, white powdery characteristics, and insoluble in ethylene glycol, 5% to 15% of pure water is added to the flame retardant to prepare an aqueous solution, which is then added to ethylene glycol, because pure water and ethylene glycol are infinitely miscible; further, considering that pure water is added to ethylene glycol, it is difficult to ignite the ethylene glycol liquid in the box body using a flamethrower, and it can only be ignited after being diverted by a cotton wick. Therefore, pure water can prevent the spread of fire and increase the ignition point of ethylene glycol fuel. The ethylene glycol liquid in the box body has an ignition point of 600°C and cannot be ignited. It will go out immediately when away from the fire and must be ignited with a wick. For example, if a piece of paper is burning, the fire can be extinguished by using ethylene glycol with pure water added; the combustion calorific value is basically not affected (the original combustion calorific value of ethylene glycol is 6000 kcal, and after adding pure water The combustion calorific value is 5500-5800 kcal. In fact, the original ethylene glycol will have some residual heat and will also be lost. The residual heat of the ethylene glycol added with pure water is less and is absorbed by the bottom of the pot. Therefore, adding pure water has little effect on the combustion calorific value). The loss of combustion calorific value can be compensated by adjusting the height of the wick, that is, the higher and larger the wick, the stronger the firepower, and the burning time remains unchanged; on the contrary, it can play a safety role. Before adding pure water, the flash point of ethylene glycol at the wick is 110℃-120 ℃, after ethylene glycol has been burning for a long time, the ethylene glycol in the box body will also be ignited. If the box body is accidentally knocked over by a drunken diners, the top cover will be separated from the refueling port, which will form a flowing fire and easily cause a fire. After adding pure water, the flash point of ethylene glycol liquid at the wick reaches over 300℃, and the ethylene glycol in the box body can never be ignited. If the box body is accidentally knocked over, the outflowing water-containing ethylene glycol will not form a flowing fire, and only the wick will continue to burn, which will not cause a fire, and the safety is greatly improved.

[0027] Furthermore, it also includes a bittering agent in a proportion of 0.001% to 0.005%, wherein the bittering agent is any one of caffeine, berberine, and citrus bitter substances. By adding the bittering agent, diners will have a resistance in terms of taste, thereby preventing diners from ingesting fuel without worries and avoiding the phenomenon of accidental drinking or ingestion.

[0028] Furthermore, it also includes 0.0005% to 0.001% of chemical flavors, where the chemical flavor is any one of benzyl alcohol and triacetin. By adding the chemical flavors, diners will have a resistance from the sense of smell, which prevents diners from ingesting fuel without worries and avoids the phenomenon of accidental drinking or ingestion.

[0029] Furthermore, considering that the box body is made of iron or stainless steel, ethylene glycol will corrode the iron box body, and a preservative is also included in a proportion of 0.001%, and the preservative is any one of triethanolamine, diethanolamine and monoethanolamine. By adding the preservative, the corrosion resistance of the iron box body can be improved.
