Description

Technical Field

[0001] The invention relates to the technical field of RCO combustion furnaces, and in particular to an RCO catalytic combustion device with an exhaust gas treatment and purification structure. Background Art

[0002] The core of the exhaust gas treatment and purification structure of the RCO burner is the catalytic combustion system. During operation, the exhaust gas is first heated to the temperature required for catalytic combustion and then sent to the catalytic combustion chamber. In the catalytic chamber, the organic pollutants in the exhaust gas react with oxygen under the action of the catalyst. After the catalytic oxidation reaction, the main components of the generated gas are carbon dioxide and water, and the temperature of the purified gas is relatively high. These high-temperature gases will then pass through the heat exchanger again to transfer the heat they carry to the newly entered low-temperature exhaust gas. During the heat transfer process, their own temperature will decrease, and then they will be discharged into the atmosphere through emission facilities such as chimneys.

[0003] In the connection between the pipeline and the furnace body of the RCO burner, the flange and bolt fixing method is currently used. This connection method performs well in ensuring the stability of the connection and can effectively ensure the sealing and structural stability of the burner during operation. However, when faced with the need to replace the pipeline or the furnace body, its disadvantages become apparent. The staff needs to loosen multiple bolts in turn, and the operation process is cumbersome and time-consuming. This not only significantly increases the labor intensity of the staff, requiring them to devote more energy to maintenance operations, but also greatly reduces work efficiency, causing many inconveniences to the daily maintenance of the burner, and seriously affecting the timeliness and efficiency of equipment maintenance.

[0004] Therefore, the traditional RCO burner can be improved to avoid the above-mentioned problems, making the disassembly or installation process of the RCO burner and the pipeline simpler and faster, thereby improving the maintenance work of the staff on the RCO burner and the pipeline.

[0018] See also Figure 1-Figure 4 , the present invention provides a technical solution: An RCO catalytic combustion device with an exhaust gas treatment and purification structure comprises a combustion furnace body 1, wherein a catalytic combustion system with a purification structure for exhaust gas treatment is installed inside the combustion furnace body 1, and the catalytic combustion system comprises a heat exchanger, a catalytic combustion chamber, a heater, a temperature controller, an exhaust gas emission device and a catalyst; The exhaust gas discharge device includes an exhaust pipe connected to the combustion furnace body 1, and at least two levels of filter screen components are arranged in the exhaust pipe, and each level of the filter screen component includes a coarse filter screen and a fine filter screen, the coarse filter screen is located on the side close to the combustion furnace body 1, and the fine filter screen is located on the side away from the combustion furnace body 1, and the exhaust pipe connected to the combustion furnace body 1 is controlled to open and close by a solenoid valve; The above-mentioned catalytic combustion system for the purification structure of the exhaust gas treatment installed inside the combustion furnace body 1 is a direct reference to the prior art, which will not be described here, and is not shown in the figure. The combustion furnace body 1 in the figure includes the catalytic combustion system for the purification structure of the exhaust gas treatment installed therein; A furnace top fixing block 2 is fixed on the combustion furnace body 1, and a pipeline connection port 3 is provided on the furnace top fixing block 2, a gas pipeline 5 is provided on the combustion furnace body 1, a bottom connecting pipe 7 extending into the pipeline connection port 3 is fixed on the gas pipeline 5, and a fixing disc 6 is fixed on the outer wall of the gas pipeline 5, and the bottom of the fixing disc 6 abuts against the furnace top fixing block 2, and two symmetrically distributed through holes 8 are provided on the fixing disc 6, a vertical round rod 4 penetrating the through holes 8 is fixed on the furnace top fixing block 2, and the vertical round rod 4 limits the position of the fixing disc 6 through the through holes 8, and a limiter for the fixing disc 6 is provided on the combustion furnace body 1, thereby playing a role in fixing the gas pipeline 5 and the combustion furnace body 1. An elastic sealing rubber ring protrudes from the portion where the outer wall of the bottom connecting pipe 7 abuts against the inner wall of the pipeline connecting port 3, and an elastic rubber gasket protrudes from the portion where the lower surface of the fixing disc 6 abuts against the upper surface of the furnace top fixing block 2.

[0019] Specifically, Figure 1 As shown, the limiting member includes a pressure rod 10 abutting against the upper surface of the fixed disc 6, the pressure rod 10 is provided with a sleeve hole 11 sleeved on the vertical round rod 4, a rotating rod 14 is rotatably connected to the combustion furnace body 1, a pressure plate 15 is provided on the pressure rod 10, and a screw hole 16 connected to the rotating rod 14 by threading is provided on the pressure plate 15, the thread on the rotating rod 14 does not completely cover the entire rotating rod 14, and when the pressure plate 15 and the rotating rod 14 are not connected by threading, the rotating rod 14 and the pressure plate 15 are slidingly connected, and both ends of the pressure plate 15 are fixedly connected with a bottom block 17, and both ends of the pressure plate 15 are provided with end holes 13 adapted to the bottom block 17, the bottom block 17 passes through the end holes 13 and abuts against the combustion furnace body 1, and the lower surface of the end of the pressure plate 15 abuts against the upper surface of the end of the pressure rod 10, and the combustion furnace body 1 is also provided with a protective member for hiding the rotating rod 14.

[0020] Specifically, Figure 3 As shown, a positioning rod 9 is fixed on the fixed disc 6, and a matching hole 12 which is slidably connected to the positioning rod 9 is opened on the pressure rod 10. Under the action of the matching hole 12 and the sleeve hole 11 through which the vertical round rod 4 passes, the position of the pressure rod 10 can be adjusted, so that the pressure rod 10 can better fix the fixed disc 6, effectively reducing the burden on the staff.

[0021] Specifically, Figure 3 As shown, the protective member includes an L-shaped bent plate 18 fixedly connected to the combustion furnace body 1, a sliding hole 19 is provided on the bent plate 18, a sliding rod 20 is slidably connected to the sliding hole 19, a handle 21 is fixed to one end of the sliding rod 20, and a sleeve block 22 is fixed to the other end, a circular sleeve groove 24 is provided on the sleeve block 22, which is sleeved on the rotating rod 14, and the bottom of the sleeve block 22 is in contact with the upper surface of the pressing plate 15.

Therefore, the handle 21 is more convenient and simple to use, and effectively avoids hand slippage.

[0023] In summary, when the gas pipeline 5 needs to be replaced, as provided in this embodiment: The handle 21 is forced to move upward, thereby compressing the spring 23 until the circular sleeve groove 24 of the sleeve block 22 below the handle 21 is separated from the rotating rod 14. At this time, the rotating rod 14 is no longer shielded by the circular sleeve groove 24 and can be directly exposed to the environment.

[0024] Rotate the rotating rod 14 exposed to the environment, and the rotating rod 14 can cause the pressure plate 15 to gradually move upward during rotation until the pressure plate 15 is no longer threadedly connected to the rotating rod 14.

[0025] When the pressing plate 15 is separated from the rotating rod 14, the bottom block 17 at the end of the pressing plate 15 is separated from the end hole 13 provided on the pressing rod 10, and the pressing rod 10 loses the fixation to the fixed disk 6. The pressing rod 10 is lifted upward until the sleeve hole 11 and the matching hole 12 provided on the pressing rod 10 are separated from the vertical round rod 4 and the positioning rod 9 respectively.

[0026] At this time, force can be applied to the gas pipeline 5 so that the bottom connecting pipe 7 at the bottom of the gas pipeline 5 is separated from the pipeline connecting port 3 opened on the combustion furnace body 1, and the disassembly of the gas pipeline 5 can be completed.

[0027] The process of installing the intact gas pipeline 5 to the combustion furnace body 1 can refer to the above-mentioned process of disassembling the gas pipeline 5.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
