Description

Technical Field

[0001] The utility model relates to the technical field of waste gas combustion, in particular to a waste gas combustion treatment device. Background Art

[0002] The combustion treatment device is one of the indispensable devices in the waste gas treatment work. The device burns the organic waste gas inside the furnace and burns the combustible waste gas to produce harmless substances for emission. In view of this, the traditional device is not perfect and there is no facility to fully burn the waste gas in the furnace, which is relatively troublesome.

[0003] A Chinese patent with publication number CN219389770U discloses a waste gas combustion treatment device, including a furnace, wherein a placement groove is provided on the inner side of the furnace. The utility model is equipped with a motor. When the waste gas enters from the inlet pipe, the waste gas enters the inner side of the connecting pipe through the spiral pipe, passes through the connecting pipe and enters the inner side of the circular pipe, and then enters the inner side of the furnace from the ventilation hole. When the waste gas floats upward under the influence of the high temperature inside the furnace, until the space between the baffle and the bottom of the furnace is filled, the waste gas moves from the bottom of the baffle toward the burner, so that the waste gas is fully in contact with the flame ejected from the burner, thereby improving the combustion rate of the waste gas.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the above-mentioned device heats the exhaust gas through an independent furnace structure to remove the incompletely burned gas in the exhaust gas. However, in actual use, the incomplete combustion of the exhaust gas is also caused by insufficient oxygen or insufficient combustion time. The method of directly heating and igniting the exhaust gas adopted by the above-mentioned device has a low effect on improving the incomplete combustion of the exhaust gas without changing the oxygen content environment. Utility Model Content

[0005] The purpose of the utility model is to provide a waste gas combustion treatment device to solve the problems raised by the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: the device can increase the oxygen content in the exhaust gas by adding air to the exhaust gas in proportion, thereby ensuring that the exhaust gas can be effectively burned thoroughly when the exhaust gas is re-ignited, reducing the residual combustible gas in the exhaust gas, and fully burning the gas that has not been fully burned again to form a harmless exhaust gas.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] Example: See Figure 1-5 The utility model provides a technical solution: comprising a shell 1, an air intake component 3 is arranged on the bottom of the shell 1, the air intake component 3 includes an air intake pipe 301, a mixing pipe 4 is arranged in the shell 1, the air intake pipe 301 is connected to the mixing pipe 4 through a U-shaped pipe 303, a control valve 302 is arranged on the air intake pipe 301, an air component 5 is arranged in the shell 1, the air component 5 includes an air intake shell 501, a blast fan 505 is arranged on the air intake shell 501, an L-shaped pipe 503 is arranged on the blast fan 505, and an inlet pipe 504 is arranged on one end of the L-shaped pipe 503 away from the air intake shell 501;

[0026] Furthermore, multiple groups of inlet pipes 504 are evenly spaced on the side wall of the L-shaped pipe 503, the inlet pipes 504 are connected to the L-shaped pipe 503, the inlet pipes 504 are connected to the side of the mixing pipe 4, a three-way pipe is arranged in the air intake shell 501, one end of the three-way pipe is connected to the air intake valve 502, and the other end of the three-way pipe is connected to multiple groups of blower fans 505. The structure of multiple groups of inlet pipes 504 can make the air and exhaust gas mix more evenly, so as to ensure that the exhaust gas can be fully burned in the subsequent process of igniting the exhaust gas.

[0027] The mixing tube 4 is provided with a combustion component 6, which includes a combustion shell 601, the bottom of the combustion shell 601 is connected to the mixing tube 4, the top of the combustion shell 601 is connected to the outlet pipe 9, a spark plug 603 is provided in the combustion shell 601 through a connecting bracket 602, and a conductive plate 605 is provided in the combustion shell 601 through a docking piece 604;

[0028] Furthermore, a connecting column is provided on the docking piece 604, and the other end of the connecting column is connected to the conductive plate 605. An insulating layer is provided on the connecting column. The electric ignition effect of the spark plug 603 can ignite the combustible gas remaining in the exhaust gas when the exhaust gas passes through the combustion shell 601. By mixing with air, the oxygen content in the exhaust gas can be increased, so that the combustible gas can be burned completely.

[0029] A cover plate 2 is provided on the shell 1, a heat insulating member 7 is provided on the combustion component 6, a through hole is provided on the cover plate 2, a rotating motor 8 is provided in the shell 1, a propeller is provided on the output end of the rotating motor 8, a connecting pipe is provided on the end of the combustion component 6 away from the mixing tube 4, a connecting piece is provided on the connecting pipe, an air outlet pipe 9 is provided on the connecting piece, the connecting piece is hollow inside, the connecting pipe is connected to the air outlet pipe 9 through the connecting piece, the propeller is rotatably connected inside the connecting piece, the propeller faces the direction of the air outlet pipe 9, the connecting piece can ensure the stable airflow connection of the device, the combination of the rotating motor 8 and the propeller can reduce the air pressure at the air outlet end, thereby ensuring the flow stability of the airflow.

[0030] This device can effectively improve the complete combustion processing of exhaust gas containing incompletely burned gases, so that the exhaust gas only contains harmless gases produced after complete combustion, avoiding the direct discharge of incompletely burned gases to cause environmental pollution. Compared with traditional devices, this device can add air to the exhaust gas in a certain proportion, thereby ensuring that the oxygen content environment required by the incompletely burned gases in the exhaust gas can be met, reducing the residual incompletely burned gases.

[0031] When the device is in working state, the air inlet component 3 and the air outlet pipe 9 of the device can effectively reduce the difficulty of combined use of the device, and improve the docking efficiency and stability of the device.

[0032] When the device assembly is installed, the exhaust gas enters the device through the air intake component 3. At this time, the speed of the exhaust gas entering the device can be controlled by adjusting the control valve 302, thereby ensuring the thoroughness of the exhaust gas treatment by the device and avoiding problems such as incomplete treatment effect caused by excessive exhaust gas flow rate.

[0033] When the exhaust gas enters the interior of the device, opening the air intake valve 502 at this time can allow external air to enter the interior of the air intake shell 501 through the air intake valve 502. The blower fan 505 structure arranged in the air intake shell 501 can generate a negative pressure environment inside the air intake shell 501, thereby ensuring that the air enters from the air intake valve 502 in one direction, and enters the mixing tube 4 through the inlet pipe 504 under the pressure of the blower fan 505, thereby avoiding the problem of exhaust gas leakage from the air intake valve 502. The air intake method using multiple sets of inlet pipes 504 can achieve a better mixing effect between the incoming air and the exhaust gas.

[0034] When the exhaust gas and air are mixed and enter the combustion component 6, the spark plug 603 in the combustion shell 601 discharges to the conductive plate 605, thereby forming an arc between the spark plug 603 and the conductive plate 605. The arc can re-ignite the gas mixed with the exhaust gas and air passing through the combustion shell 601. At this time, when the incompletely burned gas contacts the arc, air has been added to the exhaust gas through the inlet pipe 504, thereby increasing the oxygen content in the exhaust gas, ensuring that the air environment is sufficient for the incompletely burned gas to be fully burned during re-ignition. The structural combination of multiple groups of spark plugs 603 can form dense arcs inside the combustion shell 601, thereby ensuring sufficient contact with the combustible gas.

[0035] When the exhaust gas pressure is relatively low, a negative pressure airflow can be formed in the exhaust pipe 9 by starting the rotating motor 8, thereby ensuring the stability of the one-way flow of the airflow and avoiding problems such as exhaust gas backflow inside the device. At the same time, the combination of the rotating motor 8 and the propeller can reduce the air pressure at the exhaust end, so that when the spark plug 603 in the combustion component 6 ignites the incompletely burned gas, it can ensure that the combustion flame is driven by the airflow toward the direction of the insulation component 7, thereby ensuring the stability of the ignition and combustion process inside the device and avoiding problems such as backfire due to airflow backflow.
