[0041] Please refer to Figure 1 , the first embodiment of the present utility model is:

[0042] The utility model provides an ozone exhaust destruction device, comprising a base 4, a destroyer 2, a demister 1, and a fan 3. The destroyer 2, demister 1, and fan 3 are all fixed to the base 4, so that the destroyer, demister, and fan form an integral body. The fan 3, demister 1, and destroyer 2 are sequentially connected in series in the direction of ozone exhaust flow, and the fan 3 is connected to the exhaust end of the ozone exhaust. Specifically, the outlet end of the demister is connected to the air inlet of the destroyer. The connection between them can be completed in advance, that is, before sale, without the need for additional after-sales assembly steps, and is also convenient for modular transportation.

[0043] The above-mentioned fan is arranged at the air inlet end of the demister. Compared with the prior art in which the fan is arranged at the air outlet end of the breaker, this solution can effectively avoid damage to the fan due to overheated exhaust gas entering the fan after heating, better protect the fan, and extend the service life of the equipment.

[0044] In this embodiment, the demister 1 has a drain outlet at its lower end, equipped with a drain valve to facilitate the discharge of condensed water. The degassing device is divided into an upper and lower half. The upper half is equipped with a heating device, which is a heater set at a temperature of 60°C-80°C. The heater can be an existing product. The lower half is equipped with a catalytic device, which includes a uniformly distributed catalyst. The catalyst can be an existing product, such as tungsten trioxide (WO3). Tungsten trioxide is a transition metal oxide with high catalytic activity and stability, and has a certain catalytic effect on various exhaust gas components. The catalytic mechanism of tungsten trioxide is that after adsorption on its surface, oxygen molecules enter the W-OH bond by passing through the W=O bond, and then react with ozone in the ozone exhaust to produce oxygen and water. The working principle of the catalyst used in the ozone exhaust degassing device is mainly based on catalytic reaction. The catalyst surface has active sites that can absorb harmful substances in the ozone exhaust. Under the action of the catalyst, these harmful substances chemically react with the active sites on the catalyst surface, breaking down into harmless substances or easily handled intermediate products. In this process, the catalyst plays a role in reducing the activation energy of the reaction and accelerating the reaction rate, making the treatment of ozone exhaust more efficient.

[0045] Both the disruptor 2 and the demister 1 are vertical structures. The disruptor, demister, and fan form a single unit, with their center of gravity located at the center of the base. The base is a square steel frame. A meter for measuring ozone exhaust concentration is located at the outlet of the disruptor.

[0046] Specifically, the working principle of the present utility model is as follows:

[0047] During use, the remaining ozone tail gas is drawn into the air inlet of the demister through the fan, and the ozone tail gas condenses into water after passing through the demister. The condensed water is discharged from the drain outlet, and the ozone tail gas is introduced into the destroyer through the air outlet of the demister, first passing through the upper half of the destroyer, and after being heated and dried at 60℃-80℃, the ozone tail gas enters the lower half of the destroyer, where the ozone tail gas is completely catalytically destroyed under the action of the catalyst. A tester for detecting the concentration of ozone tail gas is provided at the air outlet of the destroyer to test whether the destroyed ozone tail gas meets the safety emission standards. When the safety emission standards are met, it can be discharged. In the above manner, before the ozone tail gas enters the destroyer, it first passes through the demister to effectively remove water vapor in the ozone tail gas, preventing excessive water from entering the destroyer and affecting the activity of the catalyst in the destroyer, thereby reducing the catalytic effect of ozone and failing to meet the qualified emission standards.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
