Description

Technical Field

[0001] This utility model relates to the field of petroleum processing technology, and in particular to a waste gas treatment device. Background Technology

[0002] The petroleum production and processing process generates a large amount of complex waste gas, containing various harmful substances such as hydrogen sulfide, hydrocarbons, and volatile organic compounds. These waste gases not only have pungent odors, but some components are also flammable and explosive. Direct release into the atmosphere would not only cause serious pollution to the surrounding environment and threaten human health, but could also lead to fires, explosions, and other safety accidents. Therefore, efficient and safe treatment of petroleum production and processing waste gases is crucial.

[0003] Existing methods for treating waste gas from petroleum production and processing typically involve combustion. However, combustion can cause pressure fluctuations, and excessively high pressure can damage the combustion chamber, potentially leading to explosions and other safety hazards. Furthermore, combustion treatment often leaves behind fine particles and harmful substances like sulfur dioxide, which continue to cause environmental damage. To overcome these drawbacks, this invention provides a waste gas treatment device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste gas treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste gas treatment device, comprising a base plate, a combustion tank body fixedly connected to the top of the base plate, a filter chamber fixedly connected to the top of the base plate and located on one side of the combustion tank body, an air inlet of the filter chamber and an air outlet of the combustion tank body fixedly connected, a plurality of slots being opened at the top of the filter chamber, a filter assembly being provided inside the filter chamber, an absorption assembly being provided inside the filter chamber, a pressure relief port being opened on the combustion tank body, and a pressure relief assembly being provided on the pressure relief port.

[0006] Furthermore, the filter assembly includes slide rails fixedly connected to both sides of the filter chamber and below the slot, a filter plate slidably connected to the slide rails, and a handle fixedly connected to the top of the filter plate.

[0007] Furthermore, a sealing strip is fixedly connected to the top of the filter plate.

[0008] Furthermore, the absorption assembly includes a plurality of first water pipes fixedly connected to the interior of the filter chamber, a plurality of nozzles fixedly connected to the first water pipes, a second water pipe fixedly connected to one end of the first water pipes through the filter chamber, and a valve fixedly connected to the second water pipe.

[0009] Furthermore, the pressure relief assembly includes a pressure relief pipe fixedly connected to the pressure relief port, an annular strip fixedly connected inside the pressure relief pipe, a sealing plug fixedly connected to the pressure relief pipe on one side of the annular strip, a spring fixedly connected to one side of the sealing plug, a pressure plate fixedly connected to one end of the spring, the pressure plate and the pressure relief pipe being slidably connected, and a pressure regulating assembly provided at one end of the pressure relief pipe.

[0010] Furthermore, the pressure regulating assembly includes a threaded hole at one end of the pressure relief pipe, a threaded rod is threadedly connected to the threaded hole, one end of the threaded rod is fixedly connected to one side of the pressure plate, and a throttle is fixedly connected to one end of the threaded rod.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention regulates the pressure in the combustion chamber body through a pressure relief component and adjusts the pressure during pressure relief using a pressure regulating component. When the pressure reaches a set value, the set pressure will push the spring to compress and discharge through the exhaust port on the pressure relief pipe, thus preventing damage to the combustion chamber body or even safety accidents caused by excessive pressure. The absorption component and filter component absorb fine particles and water-soluble harmful substances in the exhaust gas after combustion, and the purification effect of the exhaust gas is improved by repeatedly filtering and absorbing the gas.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, a waste gas treatment device is disclosed, including a base plate 1, a combustion tank body 2 fixedly connected to the top of the base plate 1, a filter chamber 3 fixedly connected to the top of the base plate 1 and located on one side of the combustion tank body 2, an air inlet of the filter chamber 3 and an air outlet of the combustion tank body 2 fixedly connected, a plurality of slots 4 are provided at the top of the filter chamber 3, a filter assembly is provided inside the filter chamber 3, an absorption assembly is provided inside the filter chamber 3, a pressure relief port 21 is provided on the combustion tank body 2, and a pressure relief assembly is provided on the pressure relief port 21.

[0022] As shown in the figure, the filter assembly includes slide rails 5 fixedly connected to both sides inside the filter chamber 3 and below the slot 4. Filter plates 10 are slidably connected to the slide rails 5. A handle 12 is fixedly connected to the top of the filter plates 10, which is used to filter fine particles and some harmful substances in the exhaust gas.

[0023] As shown in the figure, a sealing strip 11 is fixedly connected to the top of the filter plate 10 to seal the groove 4 and prevent exhaust gas from overflowing from the groove 4.

[0024] As shown in the figure, the absorption assembly includes several first water pipes 6 fixedly connected to the inside of the filter chamber 3. Several nozzles 7 are fixedly connected to the first water pipes 6. One end of the first water pipe 6 passes through the filter chamber 3 and is fixedly connected to a second water pipe 8. A valve 9 is fixedly connected to the second water pipe 8 for spraying water to absorb water-soluble harmful substances in the exhaust gas. The absorbed water is then discharged through the drain outlet of the filter chamber 3.

[0025] As shown in the figure, the pressure relief assembly includes a pressure relief pipe 13 fixedly connected to the pressure relief port 21. An annular strip 14 is fixedly connected inside the pressure relief pipe 13. A sealing plug 15 is fixedly connected to the pressure relief pipe 13 on one side of the annular strip 14, and a spring 16 is fixedly connected to one side. A pressure plate 17 is fixedly connected to one end of the spring 16. The pressure plate 17 and the pressure relief pipe 13 are slidably connected. A pressure regulating assembly is provided at one end of the pressure relief pipe 13 to regulate the pressure in the combustion tank body 2 and prevent excessive pressure from causing the combustion tank body 2 to explode and be damaged.

[0026] As shown in the figure, the pressure regulating component includes a threaded hole 18 at one end of the pressure relief pipe 13, a threaded rod 19 is threadedly connected to the threaded hole 18, one end of the threaded rod 19 is fixedly connected to one side of the pressure plate 17, and a handle 20 is fixedly connected to one end of the threaded rod 19 for adjusting the pressure during pressure relief.

[0027] Working principle: First, check the entire device for damage. After inspection, connect one end of the second water pipe 8 to an external water source. Then, slide the filter plate 10 into the slide rail 5 using the handle 12. The sealing strip 11 is positioned on the slot 4 to seal the slot 4, preventing exhaust gas from escaping during filtration. Next, turn the handle 20, causing the threaded rod 19 to rotate on the threaded hole 18, which in turn causes the pressure plate 17 to slide in the pressure relief pipe 13, adjusting the spring force of the spring 16 and thus regulating the pressure during pressure relief. Afterward, the exhaust gas generated from petroleum processing enters the combustion tank body 2 for combustion to remove harmful substances. After combustion, the exhaust gas enters the filter chamber 3. Then, the operator opens the valve 9, allowing water to pass through the second water pipe 8 and the first water pipe 6, and then be discharged through the nozzle 7 to absorb water-soluble harmful substances in the exhaust gas. The exhaust gas is then filtered by the filter plate 10 to remove fine particles generated by combustion. However, when the gas pressure in the combustion tank body 2 exceeds the set value, the pressure generated by the gas pressure on the sealing plug 15 can push the spring 16 to compress, thereby moving the sealing plug 15 to the exhaust port of the pressure relief pipe 13 to discharge the gas. When the gas pressure decreases, the spring 16 will push the sealing plug 15 to seal the air inlet again.
