Description

FRP combination material winding ozone disinfection tower

Technical Field

The invention belongs to the field related to the manufacture of environment-friendly equipment, and particularly relates to an ozone disinfection tower wound by FRP (fiber reinforced plastic) combined materials.

Background

Ozone, an allotrope of oxygen, is composed of 3 oxygen atoms, unlike ordinary oxygen, and has the molecular formula O3, which is the most powerful oxidant known as a broad-spectrum oxidant. Ozone is unstable in performance and rapidly decomposes into O2 and a single oxygen atom O at normal temperature, and the two single oxygen atoms O can be combined into O2. The monatomic oxygen is very active, has strong oxidizability and decomposition function, and can quickly kill various microorganisms such as germs, viruses and the like. Ozone oxidizing ability is one time higher than chlorine, sterilizing ability is 600-3000 times faster than chlorine, and bacteria and virus can be killed within a few seconds. The method for treating bacteria by ozone is to directly oxidize the cells of the bacteria, namely to destroy the genes of the DNA of the bacteria so as to achieve the effect of inhibition. The ozone treatment has the advantages of high speed, high efficiency, no residue, no secondary pollution and the like.

Ozone technology is both old and new, which was invented by german chemists in 1840 and was used in water treatment and disinfection industry in 1856. At present, ozone is widely used in the fields of water treatment, air purification, food processing, medical treatment, medicine, aquaculture and the like, and plays a great role in promoting the development of the industries.

With the development of society and the enhancement of environmental awareness of people, people put forward higher requirements on the quality of atmospheric environment, litigation events related to malodor pollution are continuously increased, and the existence of malodor is more emphasized. The malodor is one of 7 typical public hazards, and harms the health and the peace and comfort of life of people. Following pollutants such as dust, sulfur dioxide, nitrogen oxides and the like, people generally pay attention to the prevention and treatment of odor pollution, and especially, the prevention and treatment of high-concentration odor pollutant waste gas is concerned, because the high-concentration odor pollutant waste gas has the greatest harm and the greatest treatment difficulty. In recent years, many scientific research institutes are dedicated to the research work of the subject, and in order to deal with the increasing threat of the high-concentration odorous pollutant waste gas to the environment and the human health, the economic and efficient technology for degrading the high-concentration odorous pollutant waste gas is not slow. The malodorous pollutant is any gaseous substance which stimulates olfactory organs to cause people to be unpleasant and harm the living environment. In a broad sense, we refer to all odorous substances emitted in the atmosphere as malodorous gases. The malodorous gas not only can bring discomfort to the smell of people, but also can cause functional diseases such as anorexia, insomnia, memory decline, mood dysphoria and the like after long-term life in an environment polluted by the malodorous gas. Malodorous pollutant waste gases can be divided into five categories from their composition. First, sulfur-containing compounds such as hydrogen sulfide, thiols, thioethers, etc.; nitrogen-containing compounds such as ammonia, amines, amides, indoles, and the like; thirdly halogen and its derivatives such as chlorine, halogenated hydrocarbons, etc.; fourthly, hydrocarbons, such as alkane, alkene, alkyne, aromatic hydrocarbon, etc.; fifthly, oxygen-containing organic matters such as phenol, alcohol, aldehyde, ketone, organic acid and the like.

Process exhaust gases from typical industrial processes often include toxic materials and have odors that can cause air pollution if the exhaust gases are not properly treated. Moreover, if the concentration of toxic substances in the exhaust gas exceeds the regulatory limits, the health of plant personnel and the general public may be compromised. In order to control air pollutants, exhaust gas must be treated with air pollution control equipment so that the concentration of toxic substances in the exhaust gas is below the regulatory limits.

Traditional carbon steel jar body that the disinfection tower was used: the weight is large, the bearing pressure is low, the manufacturing period is long, or the transportation is troublesome, or the field manufacturing is needed, the corrosion resistance is poor, the corrosion resistance treatment is needed, and the cost is high.
