Description

Technical Field

[0001] The present invention relates to the technical field of cracking furnaces, and more specifically to a regenerative organic waste gas cracking furnace. Background Art

[0002] The working principle of a cracking furnace is to subject petroleum hydrocarbon raw materials to a cracking reaction through high-temperature heating, breaking large hydrocarbon compounds into small olefins, alkynes and other products. In this process, the raw materials are rapidly heated to a high temperature in the cracking furnace tubes, undergoing complex chemical reactions to achieve rearrangement and breaking of the molecular structure.

[0003] The patent application with the application number CN201910661907.5 discloses a regenerative organic waste gas cracking furnace, including a cracking furnace and support legs installed at the four corners of the bottom of the cracking furnace. A wind equalizing box is installed at the top of the cracking furnace, and a V-shaped impurity removal pipe is connected to the right end face of the wind equalizing box. A regenerative cracking chamber is installed at the inner bottom of the cracking furnace. First, the organic waste gas is subjected to a first-stage incomplete cracking by the cracking furnace, and then completely cracked by the regenerative cracking chamber, with a higher cracking rate and efficiency. At the same time, the ceramic regenerator stores the internal temperature of the regenerative cracking chamber, and the organic waste gas cracking generates heat, and only a small amount of natural gas is required for heating to complete the cracking, saving energy consumption. Secondly, impurity particles are blocked by the impurity removal pipe and the impurity blocking cloth to prevent impurity particles from flowing into the cracking furnace for combustion to generate other waste gases. Finally, the cracked organic waste gas is introduced into the heat exchanger through the heat transfer pipe, improving the energy utilization rate.

[0004] During the operation of existing equipment, the waste gas entering the cracking furnace is usually preheated to shorten the time required for the gas to heat up during the subsequent combustion process. However, the current preheating process still consumes a large amount of fuel, resulting in the failure to improve the overall energy utilization efficiency. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a regenerative organic waste gas cracking furnace to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A regenerative organic waste gas cracking furnace, including a first base, a right-angle plate is fixedly connected to the rear side of the first base, a first connecting pipe is fixedly connected to the top of the right-angle plate, a furnace body is fixedly connected to the top of the first connecting pipe, a combustion chamber is fixedly connected to the inner wall of the furnace body, a rotating assembly is rotatably connected to the inner wall of the right-angle plate through a bearing, and an air inlet mechanism is fixedly connected to the top of the first base. It also includes: Heat exchange mechanism, the heat exchange mechanism includes a U-shaped seat, the bottom of the U-shaped seat is fixedly connected to the first base, the top of the U-shaped seat is fixedly connected with an annular plate, and the inner wall of the annular plate is fixedly connected with a housing, so that the low-temperature exhaust gas sent into the housing and the high-temperature gas after combustion perform efficient heat exchange, and the waste heat of the gas after combustion is used to preheat the exhaust gas. This not only effectively avoids the energy waste caused by the direct discharge of high-temperature gas, but also improves the overall energy utilization efficiency of the equipment and realizes the recycling of energy. The inner wall of the housing is fixedly connected with a square plate. A second flow channel is opened on one side of the square plate close to the right-angle plate, and a first flow channel is opened on the side of the square plate away from the right-angle plate. The inner wall of the second flow channel is fixedly connected with a second heat conduction plate, and the inner wall of the first flow channel is fixedly connected with a first heat conduction plate. A first communication port is opened on the inner wall of the first flow channel, and a second communication port is opened on the inner wall of the second flow channel. A plurality of square plates are fixed in the housing, and the plurality of square plates are superposed on each other to achieve the effect of staggered flow of the gas in the first flow channel and the second flow channel. By setting the heat exchange mechanism, the exhaust gas and the high-temperature gas operate in a staggered flow manner in the housing. This design not only prolongs the gas flow path, increases the temperature transfer time, but also increases the heat exchange contact area between the exhaust gas and the high-temperature gas. This design effectively improves the heat exchange efficiency of the equipment, thereby further enhancing the overall energy utilization efficiency of the equipment.

[0007] According to the above technical solution, the inner wall of the annular plate is fixedly connected with a heating pipe, the outer wall of the heating pipe is fixedly connected with the housing, and the outer wall of the heating pipe is fixedly connected with the square plate.

Exhaust gas will enter the inner cavity two from the third connecting rod, and then enter the housing through the inner cavity one. By setting the intake mechanism, the time required for the equipment to switch the air flow pipeline is shortened, thereby effectively ensuring the continuous and stable operation of the equipment. This design can not only maintain the stability of the equipment temperature, but also ensure the continuous and sufficient supply of gas in the combustion chamber, further improving the operation stability of the equipment.

[0014] Compared with the prior art, the present invention provides a regenerative organic waste gas cracking furnace, which has the following beneficial effects: 1.

This not only effectively avoids the energy waste caused by the direct emission of high-temperature gas, but also improves the overall energy utilization efficiency of the equipment, realizing the recycling of energy.

This design effectively improves the heat exchange efficiency of the equipment, thereby further enhancing the overall energy utilization efficiency of the equipment.

[0016] 3. By setting up a rotating assembly, the present invention solves the problem that the temperature of the single-sided heat exchange mechanism rises due to long-term operation. When the temperature of one side of the heat exchange mechanism rises, the heat of the high-temperature gas cannot be effectively transferred to the waste gas, and the temperature rise of the waste gas mainly depends on the heat exchange mechanism itself, resulting in a large amount of heat in the high-temperature gas being wasted. The introduction of the rotating assembly realizes the automatic switching of the intake of the two heat exchange mechanisms, providing the necessary cooling time for the equipment, not only effectively avoiding heat waste, but also improving the energy utilization rate of the equipment.

[0017] 4. By setting up an intake mechanism, the present invention shortens the time required for the equipment to switch in the air flow pipeline, thereby effectively ensuring the continuous and stable operation of the equipment. This design not only can maintain the stability of the equipment temperature, but also can ensure the continuous and sufficient supply of gas in the combustion chamber, further improving the operation stability of the equipment.
