Detailed Description
The present invention will be further explained with reference to fig. 1, fig. 2 and fig. 3.
An apparatus for decomposing an ozone off-gas, comprising: the device comprises a base 1, a tank body 2 is arranged at the upper end of the base 1, the upper end of the tank body 2 is opened, the periphery of the tank body 2 is closed, a heating cabin 13 and a catalyst cabin 15 are respectively arranged in the tank body 2 from top to bottom, a catalyst for decomposing ozone is filled in the catalyst cabin 15, an air outlet 16 connected with the catalyst cabin 15 is arranged at the bottom of the tank body 2, a discharge opening 11 connected with the catalyst cabin 15 is arranged at the lower end of the tank body 2, and a valve is arranged on; the heating controller 6 is hermetically arranged at an opening at the upper end of the tank body 2, the heating pipe 14 is connected to the heating controller 6, and the heating pipe 14 is positioned in the heating cabin 13; the rotational flow air pump 3 is arranged on the base 1, and an air inlet of the rotational flow air pump is connected with an air outlet 16 through an air suction pipeline 4; and the demister 7 is vertically arranged, the upper end of the demister 7 is connected with the heating cabin 13 of the tank body 2, the middle part of the demister is connected with the ozone pool through the arranged air inlet 8, the lower end of the demister is provided with a sewage discharge outlet, and a sewage discharge valve 9 is arranged on the sewage discharge outlet. The cyclone air pump 3 works, air is sucked into the tank body 2 through the air suction pipeline 1, the cyclone air pump 3 exhausts air through an exhaust port 12 of the cyclone air pump 3, under the action of negative pressure, ozone in an ozone pool enters the demister 7 through the air inlet 8, moisture in ozone gas is separated in the demister 7, water is prevented from entering the catalyst cabin 15 to influence the service life of a catalyst, the gas after moisture separation enters the heating cabin 13, the heating controller 6 controls the heating pipe 14 to generate heat, the ozone gas is firstly subjected to thermal degradation and then enters the catalyst cabin 15 to react with the catalyst to perform secondary degradation, the heat generated by the heating pipe 14 also enables the catalyst to reach the optimal catalytic temperature, the decomposition efficiency is improved, through secondary decomposition, the ozone is ensured to be completely decomposed into oxygen, and finally the oxygen is exhausted into the atmosphere through the. When a certain amount of water is accumulated, the drain valve 9 is opened to drain the water. When the catalyst is invalid, the valve is opened, and the catalyst can be discharged through the discharge port 11. The operation is convenient and simple.
Preferably, the heating tube 14 has a U-shaped configuration. The heating tube is bent into a U-shaped structure, the contact area of the heating tube and the ozone is increased, and the heat exchange efficiency is improved, so that the thermal decomposition efficiency of the ozone is improved.
