Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a volatile gas treatment device for petroleum processing. Background Technology

[0002] Patent application CN218914961U includes a heat pipe device comprising at least one heat pipe, the heat pipe comprising a first part and a second part capable of heat transfer, the first part being located inside the furnace of the regenerative thermal oxidizer (RTO), and the second part being located outside the furnace; a waste heat storage device is located outside the furnace, the waste heat storage device being capable of heat conduction with the second part; when the heat conduction system is in a first operating state, the waste heat storage device stores the heat energy transferred by the second part; when in a second operating state, the waste heat storage device releases heat energy to the second part. The advantage is that, in the prior art including the aforementioned patent, the provided heat conduction system can quickly transfer excess heat from the furnace, allowing for rapid shutdown and cooling when the RTO furnace experiences overheating or other malfunctions, facilitating timely access for maintenance and repair; and the transferred heat is stored in the waste heat storage device, avoiding significant energy loss during shutdown and cooling. Furthermore, the waste heat in the waste heat storage device of this system can provide heat when the RTO is started or the furnace is kept warm, reducing the external heat demand for start-up and furnace keeping, reducing operating energy consumption and avoiding a large amount of energy loss when the system is shut down for cooling. In addition, the heat stored in the waste heat storage device can be released and transferred to the furnace interior through heat pipes.

[0003] However, in the aforementioned patents and existing technologies, regenerative thermal oxidation technology in industrial organic waste gas treatment is divided into RCO and RTO. The two have different working principles and fundamentally different requirements for temperature control and structural design, making it difficult for existing technologies to be adapted across different scenarios. RTOs rely on high-temperature combustion to oxidize organic matter, and existing improvement solutions are all designed around their high-temperature operating conditions. While these solutions can address the waste heat recovery and cooling issues of RTOs, they are not suitable for the low-temperature catalytic scenarios of RCOs. RCOs rely on low-temperature active catalysts to oxidize organic matter, and existing solutions have limitations: temperature control relies on electronic control systems, which, while achieving temperature control, have slow response times and are prone to failure in harsh industrial environments; insulation relies on traditional insulation materials, which require frequent replacement and maintenance due to thermal expansion and contraction caused by diurnal temperature variations; and dust treatment requires additional pre-treatment equipment, increasing system complexity. Furthermore, RTO improvement solutions, due to differences in operating temperature and core components, cannot be transferred to address RCO issues, and existing RCOs require additional dust removal equipment, further increasing system complexity. Summary of the Invention

[0004] The problem this invention aims to solve is to improve the convenience and adaptability of RCO temperature control without significantly increasing costs.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a volatile gas treatment device for petroleum processing, comprising a temperature control component installed outside a catalyst chamber, the temperature control component outside the catalyst chamber consisting of a mounting pipe rack, a first mounting frame, blades, and an adjustment component. The mounting pipe rack is installed outside the catalyst chamber and is hollow. The first mounting frame is installed on the mounting pipe rack, and several blades are installed inside the first mounting frame. The front of the blades is covered with a mirror sticker, and the back of the blades is coated with black paint. The adjustment component is installed behind the first mounting frame and is only installed on the sun-facing side of the equipment. The adjustment component mainly includes a second mounting frame, a wind deflector, a pull cable, and a buckle.

[0006] Preferably, the upper end of the mounting pipe rack is fixedly provided with a canopy, the mounting pipe rack is in communication with the interior of the second mounting frame, and the mounting pipe rack without the adjustment component is directly connected to the first mounting frame.

[0007] Preferably, the upper and lower ends of the mounting frame are respectively provided with a slot 1 and a protrusion 1, and the upper and lower ends of the blade are respectively provided with a protrusion 2 and a slot 2, wherein the slot 1 and slot 2, and protrusion 1 and protrusion 2 are of the same size.

[0008] Preferably, the second mounting frame is located behind the first mounting frame and connected to the mounting tube frame. Ventilation openings are provided at both the upper and lower ends of the second mounting frame. A roller is rotatably mounted inside the upper part of the second mounting frame, and several wind deflectors are provided below the roller.

[0009] Preferably, both ends of the wind deflector are slidably connected to the second mounting frame, and the wind deflectors are connected by a cable. Only one cable is provided, and the cable passes through both ends of the wind deflector. Both ends of the cable are fixedly connected to both ends of the roller shaft, and the cable is arranged in a zigzag pattern.

[0010] Preferably, a buckle is provided below the wind deflector strip to control the length of the cable, and pulleys are rotatably provided at both ends of the wind deflector strip to reduce the resistance when the cable moves.

[0011] Preferably, an air duct is provided on the shaded side of the catalytic chamber, the air duct is located on one side of the ceiling, and several Venturi tubes are fixedly installed at the lower end of the air duct, with one end of the Venturi tubes communicating with the mounting pipe rack.

[0012] Preferably, the duct is connected to an external fan and is used to blow air into the venturi tube, the lower end of which can be sealed with a cap.

[0013] Preferably, the blade is controlled by a motor, and the blade can move in a circular motion around the output shaft of the motor.

[0014] Preferably, the roller can windbreak strips.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) First, existing RCOs rely on electronic control devices for temperature control, which are prone to failure in harsh industrial environments and cannot meet the requirements of low-temperature catalysis. By using a specially designed adjustment component on the sun-facing side, combined with motor-driven double-sided functional blades, a rapid response can be achieved, reducing the risk of electronic control failure and meeting the core requirements of low-temperature catalysis of RCOs. Second, by replacing traditional insulation materials and constructing a dual insulation system, maintenance costs can be reduced. Existing RCOs rely on traditional insulation materials, which require frequent replacement and maintenance due to thermal expansion and contraction caused by day-night temperature differences. However, by using the black paint on the reverse side of the blades to absorb external light sources for heat supplementation at low temperatures, combined with the adjustment of the air intake volume by the spacing of the wind deflectors, a system of "material heat absorption + structural air control" can be formed. The dual insulation mode reduces reliance on traditional insulation materials at the source, avoids frequent replacement operations, and lowers operation and maintenance costs and workload. Finally, it integrates a dust self-cleaning function, realizing integrated temperature control and dust removal, simplifying the system structure. Existing RCOs require additional pre-dust removal equipment to treat dust on the blade surface, increasing system complexity and cost. By utilizing the hollow mounting bracket and the Venturi tube on the shaded side of the catalytic chamber, the Venturi tube enhances airflow within the temperature control component under normal conditions to assist in temperature control. After periodically sealing the lower end of the Venturi tube, the dust on the blade surface can be blown away by the fan blowing air in the opposite direction, eliminating the need for additional dust removal equipment and realizing the integration of "temperature control + dust removal" functions, simplifying the system structure. (2) Adopt a differentiated layout. Most existing RCO temperature control structures are integrated designs. Although the cooling effect is obvious, the cost is too high. In view of the strong sunlight on the sunny side, a special adjustment component is set up to achieve precise air control. In view of the relatively stable temperature on the shaded side, air ducts and venturi tubes are used to assist in airflow adjustment and dust cleaning, forming a differentiated layout of "sunny side temperature control + shaded side assistance". The temperature control efficiency can be improved without increasing the cost. The assembly and maintenance convenience are optimized, and the precise splicing of the installation frame and blades can be quickly achieved, which facilitates the improvement of the sealing when the blades are closed.

[0020] like Figures 1 to 12 As shown, the present invention provides a volatile gas treatment device for petroleum processing, including a temperature control component installed outside the catalytic chamber 1. The temperature control component outside the catalytic chamber 1 consists of a mounting frame 2, a mounting frame 4, blades 5, and an adjustment component 6. The mounting frame 2 is installed outside the catalytic chamber 1 and is hollow. The mounting frame 4 is installed on the mounting frame 2, and several blades 5 are installed inside the mounting frame 4. The front of the blades 5 is covered with a mirror sticker, and the back of the blades 5 is painted with black paint. The adjustment component 6 is installed behind the mounting frame 4 and is only installed on the sun-facing side of the equipment. The adjustment component 6 mainly includes a mounting frame 601, a wind deflector 603, a cable 604, and a buckle 605.

[0021] The upper end of the mounting bracket 2 is fixedly equipped with a canopy 3. The mounting bracket 2 is internally connected to the mounting frame 601. The mounting bracket 2 without the adjustment component 6 is directly connected to the mounting frame 4.

[0022] The upper and lower ends of the mounting frame 4 are respectively provided with slot 401 and protrusion 402, and the upper and lower ends of the blade 5 are respectively provided with protrusion 501 and slot 502. The dimensions of slot 401 and slot 502, protrusion 402 and protrusion 501 are the same.

[0023] Mounting frame 2 601 is located behind mounting frame 1 4 and connected to mounting tube 2. Ventilation openings are provided at both the upper and lower ends of mounting frame 2 601. A roller 602 is rotatably mounted inside the upper part of mounting frame 2 601, and several wind deflectors 603 are provided below the roller 602.

[0024] Both ends of the wind deflector 603 are slidably connected to the mounting frame 601. The wind deflectors 603 are connected by a cable 604. There is only one cable 604. The cable 604 passes through both ends of the wind deflector 603. Both ends of the cable 604 are fixedly connected to both ends of the roller 602. The cable 604 is arranged in a zigzag shape.

[0025] A buckle 605 is provided below the wind deflector 603. The buckle 605 is used to control the length of the cable 604. Both ends of the wind deflector 603 are rotatably equipped with pulleys 606, which are used to reduce the resistance when the cable 604 moves.

[0026] A duct 7 is installed on the shaded side of the catalytic chamber 1. The duct 7 is located on one side of the ceiling 3. Several venturi tubes 701 are fixedly installed at the lower end of the duct 7. One end of the venturi tube 701 is connected to the mounting pipe rack 2.

[0027] The air duct 7 is connected to an external fan and is used to blow air into the venturi tube 701. The lower end of the venturi tube 701 can be sealed with a cover.

[0028] Blade 5 is controlled by a motor, and blade 5 can move in a circular motion around the output shaft of the motor.

[0029] Roller 602 can rewind the windbreak strip 603.

[0030] The working principle and usage process of this invention: When the temperature control component is working, there are two situations: If the device is located in an area with a large temperature difference between day and night: When the temperature is high, the blades 5 open, then the cable 605 is loosened, and the cable 604 below the cable 605 is shortened. When the cable 604 is shortened, the spacing between the wind deflectors 603 increases. Based on this, the wind speed passing through the wind deflectors 603 can be changed by altering the spacing. When the temperature is low, especially at night, the blades 5 reverse so that the inner black paint faces outward, thereby absorbing as much external light as possible to maintain the device's temperature at low nighttime temperatures. It is worth noting that if the device experiences high temperatures at night, the blades 5 also need to open to increase the air intake. Furthermore, if the wind speed is low at night, the spacing of the wind deflectors 603 can be further increased, or they can be completely rolled up onto the roller 602. If the device is installed in an area with large temperature differences between the four seasons: when the sun is out in summer, the motor drives the blade 5 to rotate and move slowly over time, so that the mirror sticker on the outside of the blade 5 always faces the direction of the sun, thereby reducing the amount of sunlight the device receives in summer and slowing down the rise in temperature. When the device is working, the external fan always supplies air into the Venturi tube 701. Under the action of the Venturi tube 701, the air that enters the second mounting frame 601 can be drawn out from the mounting tube rack 2, thereby enhancing the airflow in the temperature control component. In addition, after a period of use, the air outlet of the Venturi tube 701 can be blocked periodically, so that the air is blown back into the second mounting frame 601 through the mounting tube rack 2, thereby blowing away the dust on the surface of the blade 5.
