Description

Technical Field

[0001] This utility model relates to the field of ozone treatment technology, specifically a recirculation energy-saving ozone exhaust gas destroyer. Background Technology

[0002] Ozone has strong oxidizing properties and a wide range of applications, including denitrification, VOCs treatment, wastewater treatment, and sterilization. Because ozone is difficult to store, industrial applications primarily rely on on-site ozone generators. However, treating the ozone exhaust gas after use remains a significant challenge. Incompletely decomposed ozone released into the atmosphere can cause a series of negative impacts on plants, animals, and the surrounding environment, leading to the development of ozone exhaust gas treatment devices: exhaust gas destroyers.

[0003] Currently, there are two principles for ozone exhaust gas treatment on the market: heating decomposition and catalytic decomposition. Small and large ozone exhaust gas destroyers mostly use pure heating, while medium-sized exhaust gas destroyers mostly use a combination of heating and catalysis. Because the exhaust gas stays in the device for a short time and the heating efficiency is not high, there are often problems such as high power consumption of the exhaust gas destroyer or incomplete heating, which leads to a decrease in exhaust gas treatment efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a recirculation energy-saving ozone exhaust gas destroyer, which has the advantages of reducing device power and improving efficiency, thus avoiding the problem of reduced exhaust gas treatment efficiency.

[0005] To achieve the goal of reducing device power and improving efficiency, this utility model provides the following technical solution:

[0006] A recirculating energy-saving ozone exhaust gas destroyer includes a base plate, a heating catalytic tank fixedly connected to the top of the base plate, an electrical control box fixedly connected to the side wall of the heating catalytic tank, and further includes:

[0007] An air inlet pipe is fixedly connected to the side wall of the heated catalytic tank, and a vortex fan and a return fan are fixedly connected to the top of the bottom plate. A first connecting pipe is fixedly connected between the heated catalytic tank and the vortex fan, a second connecting pipe is fixedly connected to the output end of the vortex fan, a third connecting pipe is fixedly connected between the second connecting pipe and the input end of the return fan, and a fourth connecting pipe is fixedly connected between the output end of the return fan and the air inlet pipe.

[0008] According to some embodiments, an exhaust pipe is fixedly connected to the top end of the second connecting pipe, and a control valve is fixedly connected to the side wall of the second connecting pipe.

[0009] According to some embodiments, a tail gas exhaust concentration meter is fixedly connected to the top of the base plate, and a connecting frame is fixedly connected to the top of the base plate, and the connecting frame is fixedly connected to the bottom of the vortex fan and the return fan.

[0010] According to some embodiments, a flange is fixedly connected to the end of the air intake pipe.

[0011] Beneficial effects

[0012] This utility model provides a recirculation energy-saving ozone exhaust gas destroyer, which has the following beneficial effects:

[0013] (1) The recirculation energy-saving ozone exhaust gas destroyer uses a vortex fan and a recirculation fan to introduce the exhaust gas after the heating and catalytic treatment into the inner cavity of the inlet pipe and mix it with the original exhaust gas, thereby increasing the inlet temperature, reducing the subsequent heating energy consumption, and reducing the power of the exhaust gas destroyer.

[0014] (2) The ozone decomposition of the reflux energy-saving ozone exhaust gas destroyer is lower and the temperature is higher after mixing and dilution. The pressure of catalyst decomposition in the inner cavity of the heating catalytic tank is lower. After heating and catalysis again, the ozone decomposition is more thorough. Therefore, the power consumption of this product is lower and the ozone exhaust gas treatment efficiency is higher. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4A recirculating energy-saving ozone exhaust gas destroyer includes a base plate 1, a heating catalytic tank 101 fixedly connected to the top of the base plate 1, an electrical control box 102 fixedly connected to the side wall of the heating catalytic tank 101, and further includes:

[0022] An air inlet pipe 2 is fixedly connected to the side wall of the heating catalytic tank 101. A vortex fan 201 and a return fan 202 are fixedly connected to the top of the bottom plate 1. A first connecting pipe 203 is fixedly connected between the heating catalytic tank 101 and the vortex fan 201. A second connecting pipe 204 is fixedly connected to the output end of the vortex fan 201. A third connecting pipe 205 is fixedly connected between the second connecting pipe 204 and the input end of the return fan 202. A fourth connecting pipe 206 is fixedly connected between the output end of the return fan 202 and the air inlet pipe 2.

[0023] An exhaust pipe 207 is fixedly connected to the top end of the second connecting pipe 204, and a control valve is fixedly connected to the side wall of the second connecting pipe 204.

[0024] It should be noted that: ozone is introduced into the inner cavity of the heated catalytic converter 101 through the intake pipe 2. The heated catalytic converter 101 heats and catalyzes the ozone, causing it to decompose harmlessly. The decomposed ozone, under the action of the vortex fan 201, enters the second connecting pipe 204 from the heated catalytic converter 101 through the first connecting pipe 203. Part of the decomposed ozone is discharged through the exhaust pipe 207, and part of the ozone exhaust gas, under the action of the return fan 202, enters the inner cavity of the intake pipe 2 through the third connecting pipe 205 and the fourth connecting pipe 206. The ozone is mixed with the original ozone. Specifically, a portion of the treated and heated exhaust gas is added to the inner cavity of the intake pipe 2. After mixing with the original exhaust gas, the temperature of the exhaust gas intake is increased through heat transfer, reducing internal heating energy consumption and thus reducing the power consumption of the exhaust gas destroyer. In addition, the ozone concentration in the mixed and diluted exhaust gas is lower and the temperature is higher, resulting in lower pressure for the catalyst decomposition in the inner cavity of the catalytic tank 101. After the heating and catalytic process, the ozone decomposition is more thorough. Therefore, this product has lower power consumption and higher ozone exhaust gas treatment efficiency.

[0025] Reference Figures 1-4 The exhaust gas concentration meter 3 is fixedly connected to the top of the base plate 1, and the connecting frame 301 is fixedly connected to the top of the base plate 1. The connecting frame 301 is fixedly connected to the bottom end of the vortex fan 201 and the return fan 202.

[0026] Flange 302 is fixedly connected to both ends of the intake pipe 2;

[0027] It should be noted that the ozone concentration emitted from the exhaust pipe 207 can be analyzed by the exhaust gas concentration meter 3, thereby controlling the emission amount of the device. The vortex fan 201 and the return fan 202 are fixed to the surface of the base plate 1 by the connecting frame 301. The flange 302 facilitates the connection between the air inlet pipe 2 and the external pipe, thereby facilitating the input of ozone into the heating catalytic tank 101.

[0028] Operating method: Ozone is introduced into the inner cavity of the heating catalytic tank 101 through the air inlet pipe 2. The heating catalytic tank 101 heats and catalyzes the ozone, causing it to decompose harmlessly. The decomposed ozone is then introduced into the second connecting pipe 204 through the first connecting pipe 203 by the action of the vortex fan 201. Part of the decomposed ozone is discharged through the exhaust pipe 207, and part of the ozone exhaust gas is introduced into the inner cavity of the air inlet pipe 2 through the third connecting pipe 205 and the fourth connecting pipe 206 by the action of the return fan 202, where it mixes with the original ozone.

[0029] That is, a portion of the treated and heated exhaust gas is added to the inner cavity of the intake pipe 2. After mixing with the original exhaust gas, the temperature of the exhaust gas intake is increased through heat transfer, reducing the internal heating energy consumption and thus reducing the power consumption of the exhaust gas destroyer. In addition, the ozone concentration of the mixed and diluted exhaust gas is lower and the temperature is higher, and the pressure of catalytic decomposition is lower. After the heating and catalytic process, the ozone decomposition is more complete. Therefore, the power consumption of this product is lower and the ozone exhaust gas treatment efficiency is higher.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
