Description

Technical Field

[0001] This utility model relates to the field of ozone decomposition technology, specifically to an ozone decomposition cylinder and decomposition device. Background Technology

[0002] Ozone (O3), as a strong oxidant, is widely used in water quality analyzers for sterilization or oxidation reactions. However, residual ozone can corrode instrument valves, pipelines, and other components, and excessive ozone emissions can harm the environment. Several traditional decomposition methods also have corresponding problems.

[0003] 1. Catalytic decomposition method: The device requires frequent replacement of the catalyst to decompose ozone, resulting in excessively high maintenance costs.

[0004] 2. The ultraviolet decomposition method requires long-term contact, which is difficult to meet the real-time processing requirements of online instruments;

[0005] 3. Hot air decomposition method has too high energy consumption and is not suitable for small equipment.

[0006] Furthermore, ozone decomposition devices that use heating decomposition are mostly designed for industrial exhaust gases or high-concentration ozone, making them difficult to adapt to low-concentration, low-flow-rate ozone decomposition scenarios in online water quality analyzers. Utility Model Content

[0007] The purpose of this invention is to provide an ozone decomposition cylinder and device to efficiently and completely decompose residual ozone in online water quality analyzers, preventing oxidative corrosion. To achieve the above objective, this invention adopts the following technical solution:

[0008] This utility model discloses an ozone decomposition cylinder, comprising: an outer cylinder, an inner cylinder, and a cylinder cover. The inner cylinder is fitted inside the cavity of the outer cylinder, and the bottom of the inner cylinder is provided with a through hole. Furthermore, a plurality of annular partitions are provided on the outer wall of the inner cylinder.

[0009] The cylinder cover is installed on the top of the inner cylinder and the outer cylinder, and the cylinder cover is provided with an air inlet and an air outlet. The air inlet is connected to the inner cylinder, and the air outlet is connected to the cavity between the outer cylinder and the inner cylinder. Both the air inlet and the air outlet are equipped with air supply pipes.

[0010] The cylinder cover is also provided with a heating rod mounting hole for connecting an external heating rod.

[0011] Furthermore, a sealing gasket is provided between the cylinder cover and the outer cylinder and the inner cylinder.

[0012] The top of the outer cylinder is provided with several fixing bolts, and the cylinder cover is provided with corresponding fixing holes. When the cylinder cover is fitted onto the fixing bolts, it is locked by fixing nuts.

[0013] Furthermore, the connecting end of the gas pipeline is provided with an installation joint, which has an external thread and a tapered interface at the bottom. The shapes of the air inlet and exhaust port correspond to the installation joint, and are divided into upper and lower parts. The inner wall of the upper part is provided with an internal thread corresponding to the external thread, and the diameter of the lower part corresponds to the tapered interface, so that the tapered interface is fitted into it to form a seal.

[0014] Preferably, the mounting connector is an engineering plastic connector, and the connection between the mounting connector and the air inlet or exhaust port is filled with sealant.

[0015] This utility model also discloses an ozone decomposition device, including: an ozone decomposition cylinder, a PLC controller, a heating rod, and a temperature sensor. The cylinder cover of the decomposition cylinder is provided with a probe fixing position for mounting the temperature sensor. The temperature sensor and the heating rod are both electrically connected to the PLC controller. The PLC controller controls the heating rod according to the temperature data.

[0016] The heating rod has an external thread at the connection end with the heating rod mounting hole, and a corresponding internal thread in the heating rod mounting hole. The two are fixed by a threaded connection.

[0017] Furthermore, the decomposition cylinder is fitted with a protective shell, and a corresponding opening is provided at the top for the power cords of the heating rod and temperature sensor, as well as the gas supply pipe, to pass through.

[0018] Preferably, the space between the protective outer shell and the decomposition cylinder is filled with heat-insulating cotton.

[0019] Preferably, the protective shell is made of engineering plastic sheets.

[0020] After adopting the above technical solution, the present invention has the following effects:

[0021] 1. The decomposition cylinder of this utility model adopts a double-layer structure. Ozone enters the space between the inner cylinder and the outer cylinder through the through hole at the bottom of the inner cylinder. The residence time of ozone in the cavity is increased by the partition set between the inner cylinder and the outer cylinder to ensure complete decomposition of ozone.

[0022] 2. This utility model installs a temperature sensor and connects the temperature sensor and heating rod to a PLC controller. The PLC controller uses the temperature data transmitted by the temperature sensor to control the heating action of the heating rod, thereby protecting the device and preventing the gas pipe installation joint from melting due to continuous heating.

[0023] 3. This utility model has an outer shell on the outside of the decomposition cylinder, and the outer shell is filled with heat insulation cotton, so that the device has excellent insulation performance and heat resistance. Attached Figure Description

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 9 As shown, this utility model discloses an ozone decomposition cylinder, including: an outer cylinder 11, an inner cylinder 12 and a cylinder cover 13. The inner cylinder 12 is fitted into the cavity of the outer cylinder 11, and a through hole 121 is provided at the bottom of the inner cylinder 12. A plurality of annular partitions 122 are provided on the outer wall of the inner cylinder 12.

[0039] The cylinder cover 13 is installed on the top of the inner cylinder 12 and the outer cylinder 11, and the cylinder cover 13 is provided with an air inlet 132 and an exhaust 133. The air inlet 132 is connected to the inner cylinder 12, and the exhaust 133 is connected to the cavity between the outer cylinder 11 and the inner cylinder 12. Both the air inlet 132 and the exhaust 133 are equipped with gas supply pipes 14 to input ozone and discharge oxygen. Usually, the gas supply pipe 14 is a Teflon pipe. In some other embodiments, the gas supply pipe 14 can also be a PEEK pipe.

[0040] The cylinder cover 13 is also provided with a heating rod mounting hole 131 for connecting an external heating rod.

[0041] In this embodiment, the decomposition cylinder 1 is made of stainless steel, which can provide good heat conduction. When ozone enters the inner cylinder 12 through the air inlet 132 and is dispersed through the through hole 121 into the cavity between the outer cylinder 11 and the inner cylinder 12, the ozone at different locations can be fully heated and decomposed. At the same time, the partition 122 can increase the residence time of ozone in the cavity until it is decomposed into oxygen and then discharged from the exhaust hole 133.

[0042] In this embodiment, a sealing gasket 15 is also provided between the cylinder cover 13 and the outer cylinder 11 and the inner cylinder 12. Furthermore, a number of fixing bolts 111 are provided on the top of the outer cylinder 11, and corresponding fixing holes 134 are provided on the cylinder cover 13. After the cylinder cover 13 is fitted onto the fixing bolts 111, it is locked by fixing nuts 112.

[0043] Secondly, in this embodiment, the connecting end of the gas pipe 14 is provided with a mounting connector 141. The mounting connector 141 is provided with an external thread and a tapered interface at the bottom. The shapes of the air inlet 132 and the exhaust port 133 correspond to those of the mounting connector 141 and are divided into upper and lower parts. The inner wall of the upper part is provided with an internal thread corresponding to the external thread of the mounting connector 141, and the diameter of the lower part corresponds to the tapered interface, so that the tapered interface is fitted into it to form a seal.

[0044] Since the air supply pipe 14 connecting the air inlet 132 and the exhaust port 133 is usually made of plastic, in order to avoid excessive heating causing the mounting joint 141 to melt, which would lead to blockage of the air intake or exhaust passage and create a safety hazard, in some embodiments, the mounting joint 141 is an engineering plastic joint, and the connection between the mounting joint 141 and the air inlet 132 or the exhaust port 133 is filled with sealant. Usually, the mounting joint 141 is a PEEK joint, and the sealant is epoxy resin. This can prevent the mounting joint 141 from melting due to continuous heating.

[0045] like Figure 10 and Figure 11 As shown, this utility model also discloses an ozone decomposition device, including: the aforementioned ozone decomposition cylinder 1, a PLC controller 4, a heating rod 2, and a temperature sensor 5, combined with... Figure 4 As shown, a probe fixing position 135 is provided on the cylinder cover 13 of the decomposition cylinder 1 to install the temperature sensor 5. The temperature sensor 5 and the heating rod 2 are both electrically connected to the PLC controller 4. The PLC controller 4 controls the heating rod 2 according to the temperature data. When the temperature of the decomposition cylinder 1 reaches the maximum limit, the heating rod 2 stops heating to reduce safety hazards and protect the device.

[0046] The heating rod 2 has an external thread at the connection end with the heating rod mounting hole 131, and the heating rod mounting hole 131 has a corresponding internal thread. The two are fixed by threaded connection.

[0047] In this embodiment, the decomposition cylinder 1 is fitted with a protective outer shell 3 made of engineering plastic sheets, and a corresponding opening is provided at the top for the power cords of the heating rod 2 and temperature sensor 4, as well as the gas supply pipe 14, to pass through. Meanwhile, heat insulation cotton (not shown in the figure) is filled between the protective outer shell 3 and the decomposition cylinder 1. The protective outer shell 3 is typically made of phenolic resin polymer material, which has excellent insulation and heat resistance, and the heat insulation cotton (not shown in the figure) also has heat insulation and anti-electric shock effects.

[0048] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
