" hot type ozone tail gas decomposer " commonly used at present is to make according to the physical characteristic of ozone, and when temperature was heated to 350 ℃, the half-life of ozone just can 100% decomposition in 1.5～2s less than 0.04s.But also there is certain problem in these class methods: the one, because ozone has strong corrosivity, therefore the antiseptic property to electric heating tube has proposed very high requirement; Traditional teflon coatings anticorrosive electric heater, though have good antiseptic property, its maximum operation (service) temperature has only about 280 degree, can not reach the cardinal temperature requirement that ozone decomposes 380 required degree far away.The 2nd, because the decomposable process of ozone is an exothermic reaction, the variation of (when the power of heater is constant) tail gas ozone concentration will inevitably cause the variations in temperature of the final tail gas after the decomposition; " hot type ozone tail gas decomposer " certain risk of ubiquity, namely when ozone concentration in the tail gas surpassed certain limit, final ozone tail gas temperature is inevitable sharply to raise, thereby causes the infringement of equipment and influence life safety.The 3rd, because ozone tail gas exists a large amount of steam to bring negative effect to equipment and operation usually, mainly show as: steam heating back volume can expand, and the equipment tube wall is produced pressure; Water vapour has certain oxide etch effect to the equipment pipe material inner wall, and acceleration equipment is aging; Also steam is heated in the time of heating ozone, make a large amount of idle works, increased substantially operating cost.
Summary of the invention
The purpose of this utility model is too high in order to solve the cost that exists in the prior art, and ozone decomposes not exclusively, and service life is short, and problem such as too high automatic control requirement and operating cost and a kind of brand-new ozone resolution model is provided.
The technical solution of the utility model is a kind of electric heater of anti-ozone, is made up of the cavity of anti-ozone, heater, reative cell, observing and controlling element etc.; It is characterized in that being: air inlet and exhaust outlet are arranged on the described cavity of anti-ozone; Described air inlet is connected on the drier; The drier of described drier is molecular sieve, and described drier is the two drying chambers parallel-connection structure; The shell of described heater uses the material of anti-ozone; The described material of anti-ozone is nichrome 800 (Incoloy800); Establish many group stroke dividing plates in the described reative cell, described stroke dividing plate is for being installed in the dividing plate of described reative cell both sides respectively, and it forms acute angle mutually, and this acute angle is that 30 degree are between 60 degree; Described observing and controlling element comprises heater temperature sensor, medium temperature sensor, exhaust outlet temperature sensor.This device is that 380 degree are to 420 degree to the ozone tail gas heating-up temperature.In actual applications can be as required with the synthetic boundling heater of several Heater group.
The beneficial effects of the utility model are: the cost of 1, having avoided catalytic type equipment to exist is too high, and ozone decomposes not exclusively, and the automatic control cost is crossed problems such as height; Problems such as the heat energy loss that has also solved existing hot type equipment existence is big, operating cost is too high, and service life of equipment is short.2, provide that a kind of to have a long-life, high efficiency, security good, and investment and the low device of operating cost.
