Description
Technical Field
The utility model relates to the technical field of disinfection equipment, in particular to an ozone water preparation device and a disinfector with the ozone water preparation device.
Background
In recent years, with the deep development of the open to the outside in China, the quantity of animals and animal products entering and exiting from the port of China is continuously increased, the risk of introducing animal epidemic diseases, particularly serious animal epidemic diseases with serious harm, is increased more and more, and the animal epidemic diseases pose potential threats to the development of animal husbandry and human health in China. In particular to foot-and-mouth disease (Aftosa, common names of aphtha and Pianzaihuang) belonging to A class infectious diseases specified by the international animal disease agency, which is listed as the head of A class livestock infectious diseases by the international animal disease agency (OIE), and is also an infectious disease specified by the Ministry of agriculture of China, and is acute, hot and highly contact infectious diseases caused by foot-and-mouth disease viruses. The disease mainly attacks artiodactyl animals such as cattle, sheep, pigs and the like, is characterized by fever, oral mucosa, hoof and breast skin blister and fester, has the epidemiological characteristics of fast prevalence, wide spread, acute morbidity, great harm and the like, has the disease incidence of 50-100% in epidemic areas, has higher calf mortality, and has lower contents in other areas, and occasionally infects people. At present, the international animal epidemic department puts a plurality of countries in the world into the foot-and-mouth disease epidemic area.
Vesicular Stomatitis (VS), also known as nasal sore, aphtha, rotten tongue disease and the like, is an acute high-contact infectious disease of multiple mammals caused by vesicular stomatitis virus, is relatively easy to infect animals such as horses, cattle and pigs, and can also infect sheep-Yang and goats, is listed as an epidemic disease which needs to be notified by the international bureau of zoonosis, is listed as a foreign animal disease in China, and is listed as a second-class epidemic disease in the national animal quarantine objects of foreign and foreign countries.
According to the technical specification of epidemic prevention and disinfection of imported and exported animals, peroxyacetic acid and chlorine-containing disinfectants are adopted to spray and disinfect the imported and exported port airplanes, loading and unloading animal isolation areas, isolation fields, animal cages and bedding materials, but the defects of the two disinfectants are very obvious:
1. peroxyacetic acid: peracetic acid has a certain toxicity and a very strong corrosiveness, has a strong irritation to the skin and eyes, can cause severe burns to the skin, can cause irreversible damage or even blindness by direct contact of the eyes with liquids, can be fatal when swallowed, and can cause irritation and damage to the respiratory tract by the inhalation of vapors therefrom.
2. Chlorine-containing disinfectants: chlorine-containing disinfectants, like peracetic acid, are highly irritating to human skin and eyes, with the greatest disadvantage of being residual and corrosive. The chlorine-containing disinfectant has extremely high residue, can not be automatically degraded in nature, and currently, various related industries in China impose regulations on residual chlorine in sterilized wastewater, and require that residual chlorine treatment is carried out in the wastewater discharge process. In addition, chlorine has strong persistent corrosion characteristics on metals, particularly has irreversible damage on ships, airplanes and vehicles in the port, and a large number of metal objects such as used cages and boxes, and is easy to cause serious potential safety hazards and national property loss risks.
Other conventional disinfection methods include ultraviolet rays, high temperature steam and 3 kinds of ozone gas:
(1) ultraviolet rays irradiate dead angles, and only when the ultraviolet rays irradiate the surface of an object and reach a certain intensity, the sterilization effect is achieved, the sterilization effect is poor, the action time is long, and the ultraviolet rays generally irradiate for more than 6 hours. The lamp tube has high energy consumption, short service life and high replacement cost.
(2) High-temperature steam is only suitable for killing in a small space, the energy consumption is high, the disinfection time is long, the sterilization effect is poor, the articles need to be resistant to high temperature, and toxic substances are easy to separate out.
(3) Ozone gas, the most widely used ozone synthesis method at present, is to adopt a cold high voltage corona discharge technology, including a high frequency high voltage discharge method, a ceramic surface discharge method and the like, to directly convert oxygen in air into ozone under the action of high voltage. To avoid NOx, pure oxygen can be used as the feedstock, but at a cost that is significantly higher, and the cost of air purifying oxygen is about twice that required to produce ozone from pure oxygen.
With the addition of WTO in China, the international trade of animals and animal products is increased, foreign animal epidemic diseases are prevented from being transmitted into China, and special research and development are carried out on disinfectants and disinfectors for foot-and-mouth disease and vesicular stomatitis of entry animals, particularly research and development of the disinfectors and disinfectors simultaneously have the following characteristics: the disinfectant and the disinfection apparatus have the advantages of high disinfection speed, stable performance, no corrosion to articles, low toxicity to people and livestock, small irritation, no residual toxicity after disinfection, easy operation of the disinfection apparatus, low cost, urgency and necessity, and important significance for protecting the healthy development of the animal husbandry in China.
