Description

Technical Field

[0001] This utility model relates to the field of exhaust gas emission technology, specifically to a safe and efficient combustion cylinder for high-concentration self-igniting exhaust gas. Background Technology

[0002] Exhaust gas is the waste gas emitted from various equipment during operation after fuel combustion or chemical reactions. Its complex composition can harm the environment and human health. Therefore, exhaust gas needs to be fully reacted and discharged through a combustion chamber. Exhaust gas combustion chambers are key equipment for treating exhaust gas emissions from industrial production, transportation, and other fields. They are mainly used for secondary combustion treatment of exhaust gas containing combustible components, achieving energy recovery and pollutant reduction. The structure of an exhaust gas combustion chamber mainly consists of a combustion chamber, an air inlet, an exhaust gas inlet, an ignition device, a combustion air supply system, and an exhaust port. The combustion chamber is the core area and is usually made of high-temperature and corrosion-resistant metal or ceramic materials, capable of withstanding high temperatures and chemical corrosion. The air inlet is used to input combustion air, and the exhaust gas inlet is used to input the exhaust gas to be treated. However, existing combustion chambers cannot fully combust the exhaust gas during use, which can easily lead to environmental impacts from the exhaust gas inside, making them inconvenient to use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a high-concentration self-igniting exhaust gas safe and efficient combustion cylinder, including a reaction box 10, a support rod 20, a main body 30, a flame tube 301, an igniter 302, an air inlet 303, a transport pipe 40, a fuel nozzle 1 401, a cavity 402, a partition 403, a fuel nozzle 2 404, a pipe 405, a pump body 50, an exhaust pipe 501, and a one-way valve 502;

[0031] This exhaust gas safe and efficient combustion chamber facilitates rapid combustion. The specific implementation method is as follows:

[0032] Support rods 20 are symmetrically mounted on the surface of the reaction chamber 10, and a main body 30 is mounted on the surface of the support rods 20. A flame tube 301 is mounted on the inner surface of the main body 30, and an igniter 302 is installed inside the main body 30 and the flame tube 301. An air inlet 303 is installed on one side of the reaction chamber 10, and a transport pipe 40 is connected to the surface of the air inlet 303. A fuel nozzle 401 is connected to the end of the transport pipe 40. A cavity 402 is provided inside the reaction chamber 10, and a partition 403 is installed inside the cavity 402. A second fuel nozzle 404 is installed inside the main body 30 and the flame tube 301, and the other end of the fuel nozzle 404 is connected to a pipe 405. The end of the pipe 405 is connected to the transport pipe 40. The surface of the reaction chamber 10... A pump body 50 is installed on the surface of the reaction chamber 10, and an exhaust pipe 501 is connected to the surface of the reaction chamber 10. A one-way valve 502 is installed inside the exhaust pipe 501. The end of the main body 30 is inserted into the interior of the reaction chamber 10, and the end of the flame tube 301 is located inside the reaction chamber 10. Both ends of the flame tube 301 are open. A fuel nozzle 1 401 is located at the air inlet of the flame tube 301. The air inlet 303 is correspondingly located inside the cavity 402, and the end of the cavity 402 is correspondingly located at the air inlet of the flame tube 301. An igniter 302 is located at the end of the fuel nozzle 1 401, and a fuel nozzle 2 404 is located at the end of the flame tube 301. The partition 403 is a screw conveyor structure and is arranged around the interior of the transport pipe 40.

[0033] Gas enters the fuel nozzle 401 through the transport pipe 40. The fuel nozzle 401 sprays the fuel out at the air inlet of the flame tube 301. At the same time, the gas is diverted through the transport pipe 40 into the pipe 405 and then into the fuel nozzle 404. At this time, the fuel nozzle 404 sprays the gas out at the end of the flame tube 301.

[0034] The exhaust gas enters the inlet 303 through an external conveying mechanism. At this time, the exhaust gas enters the cavity 402 through the inlet 303, causing the gas to rotate and be transported along the surface of the baffle 403. The gas then moves through the cavity 402 to the air inlet of the flame tube 301 and enters the flame tube 301. Due to the rotation of the baffle 403, the gas rotates and enters the flame tube 301 under the drive of inertia, allowing the exhaust gas to fully contact the fuel sprayed from the fuel nozzle 1 401. At this time, the igniter 302 is turned on to ignite the fuel. The fuel then burns the exhaust gas inside the flame tube 301. Simultaneously, the gas sprayed from the fuel nozzle 2 404 ignites the unreacted exhaust gas, improving the ignition efficiency of the device.

[0035] The combustion gas enters the reaction chamber 10 through the flame tube 301, so that the sodium hydroxide solution in the gas comes into contact with the reaction solution inside the reaction chamber 10. At this time, the sodium oxide solution inside the reaction chamber 10 decomposes the gas and reacts with the acidic gas in the exhaust gas. Then the gas produced after decomposition is discharged through the exhaust pipe 501. The one-way valve 502 can prevent external gas from entering the exhaust pipe 501.

[0036] Working principle: When using this high-concentration self-igniting exhaust gas safe and efficient combustion tube, a baffle 403, fuel nozzle 404, pipe 405 and pump body 50 are set up to allow the gas to rotate and enter the interior of the flame tube 301, so that the fuel and exhaust gas can fully contact each other. There are two fuel discharge points inside the flame tube 301 to facilitate rapid combustion. The pump body 50, exhaust pipe 501 and one-way valve 502 are set up to react the exhaust gas through the solution inside the reaction chamber 10, which increases the overall practicality.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
