Description

Waste engine oil spray device for treating volatile organic compounds

technical field

The utility model relates to a purification system in the painting industry, in particular to a waste engine oil spraying device for treating volatile organic matter.

Background technique

At present, the whole society is actively advocating the construction of a resource-saving, environment-friendly and innovative society, and energy conservation and emission reduction have become the main theme of the development of major enterprises. The pollution of volatile organic compounds (VOCs) emitted unorganized in the coating industry has attracted much attention.

When a painting company is painting a product, a large amount of volatile organic waste gas (VOCs) will be generated by the impact of the spraying airflow. The main components are: particulate matter, methyl methacrylate, butyl methacrylate, butyl acrylate, butyl acetate, non-methane total hydrocarbons, etc.

Methyl methacrylate is an organic compound, also known as MMA, referred to as methyl methyl ester, is an important chemical raw material; its appearance and properties: colorless volatile liquid, and has a strong spicy taste, flammable; its dissolution Properties: Soluble in ethanol, ether, acetone and other organic solvents, slightly soluble in ethylene glycol and water, flammable, stable stability, easy to polymerize in the presence of light, heat, ionizing radiation and catalysts.

Butyl methacrylate is a colorless, sweet and ester-like liquid at room temperature. It is insoluble in water and miscible in most organic solvents such as alcohol and ether. Butyl methacrylate is a slightly toxic organic chemical product. It is harmful to the body if inhaled, taken orally or absorbed through the skin. Its vapor or mist can irritate the eyes, mucous membranes and respiratory tract. The symptoms of poisoning include burning sensation, coughing, wheezing, and laryngitis. , shortness of breath, headache, nausea and vomiting. Butyl methacrylate is a hazardous chemical, flammable, and can form an explosive mixture with air, which can cause combustion and explosion when exposed to open flame and high heat.

Butyl acrylate is a colorless transparent liquid, insoluble in water, but miscible in ethanol and ether; Soluble in most hydrocarbon compounds; environmental protection solvent oil 100# molecular formula is C9H12, molecular weight is 116.16.

The volatile organic waste gas (VOCs) synthesized by these pollution factors is suspended and dispersed in the space during operation, resulting in serious air quality pollution, which brings great hidden dangers to fire safety and safe production. This harsh environment also seriously affects the normal use of instruments, restricts the improvement of product quality in the coating industry, and endangers the physical and mental health of employees.

At present, the spray devices commonly used in the purification equipment used in the coating industry mainly include the following types:

1. Cylindrical spraying device, this kind of spraying device is mainly made of external cylindrical reinforced polypropylene material, and the internal sprinkler head is sprayed under the starry sky. The medium used is water, and the water mist is sprayed on the filler in the lower layer. , forming water droplets and converging into a water flow, which flows down to the circulating water tank under the action of gravity, and the waste gas passes through the packing layer from bottom to top to achieve gas-liquid separation, and the separated gas directly enters the purification system for treatment. However, due to the use of water spraying, the circulating water needs to be dosed and cleaned regularly, and the daily maintenance workload is very large; in addition, the water body after dosing is polluted, and the wastewater needs to be polluted before it can be discharged to meet the standard. This not only causes secondary pollution, but also has high costs, which cannot meet the basic requirements of energy conservation and environmental protection.

2. Rectangular spray tower, since the spray tower is a two-stage or multi-stage purification device, the height of the tower body is about 6 meters or more. If it is installed inside the production workshop, it will touch the running cars in the production workshop, so it cannot Meet the needs of the height of the production workshop; in addition, the medium used in the spray tower is also water, and the circulating water needs to be dosed and cleaned regularly, which will also cause secondary pollution of the water. Not only the sewage needs to be treated, but the cost is too high to achieve Basic requirements for energy saving and environmental protection.

In view of this, researchers in the field of purification in the painting industry are committed to developing a waste engine oil spray device for the treatment of volatile organic compounds, so as to improve and upgrade the VOCs treatment equipment in the painting industry.
