Description
Technical Field
[0001] The utility model belongs to the technical field of catalytic combustion equipment, and in particular relates to a catalytic combustion equipment equipped with a burner for direct heating. Background Art
[0002] Catalytic combustion equipment refers to a device that burns under the action of a catalyst. The working principle of the catalytic combustion device is: with the help of a catalyst, the organic waste gas is flamelessly burned at a lower ignition temperature, and the organic waste gas is decomposed into non-toxic carbon dioxide and water vapor. The catalytic burner electrical control system consists of a PLC controller, a text display, a variable frequency speed regulator, an igniter, an ultraviolet sensor, a thermocouple and other electronic control equipment and a fan. In addition, a zero pressure valve is used to adjust the ratio of gas to air.
[0003] Existing catalytic combustion equipment usually directly transports exhaust gas into the interior. Since the equipment lacks a mechanism to effectively preheat the exhaust gas, it takes a lot of time to heat the exhaust gas after entering the catalytic combustion equipment, resulting in a very slow combustion rate, which affects the catalytic efficiency of the equipment.

The observation window and the door body are welded into an integrated structure, and a handle is installed on the door body on the observation window side.
[0012] Compared with the prior art, the embodiments of the present application have the following beneficial effects:
[0013] 1. The burner can effectively preheat the exhaust gas in the box, reduce the heating time required for the exhaust gas to enter the equipment, and thus improve the catalytic efficiency of the equipment. By turning on the power, fresh air enters the burner from the air inlet, first filtered out impurities and dust by the filter, and then enters the combustion chamber, mixed with the internal natural gas, and ignited by the burner. Since the main component of natural gas is CH4, CO2 and H2O are generated after full combustion, so the tail gas does not pollute the atmosphere. It is a clean energy and is beneficial to environmental protection. At the same time, natural gas is used to directly burn air for heating, heating the circulating air, and energy loss is very small. Natural gas can be used as a heating source, which solves the problem that high-power electricity consumption cannot be used in certain occasions. The ceramic heat storage rod makes it easy to store excess heat and release it when the heat is insufficient, so as to achieve continuous heat supply. After that, the hot air is drawn into the box by the exhaust fan. The burner can effectively preheat the exhaust gas, reduce the heating time required for the exhaust gas to enter the equipment, and thus improve the catalytic efficiency of the equipment.
[0014] 2. The slider on the filter cooperates with the slide rail to drive the filter into the interior of the burner. As the filter goes deeper, the positioning cylinder will be inserted into the interior of the positioning rod. One end of the positioning cylinder will drive the first magnetic plate to slide inside the positioning rod. When the filter is completely inserted into the interior of the burner, the first magnetic plate just touches the surface of the second magnetic plate, and the first and second magnetic plates are attracted to each other by the magnetic force between them, thereby fixing the position of the filter. When it needs to be disassembled, pull the filter outward with force to make the positioning rod detach from the positioning cylinder and then slide out from the slide rail, so that the filter will absorb too many impurities after long-term use, so that the filter can be disassembled and cleaned.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model provides a catalytic combustion device equipped with a burner for direct heating, such as Figure 1-3 As shown, one side of the box body 1 is fixedly connected with an air inlet pipe 4, and an air inlet valve is fixedly installed on the air inlet pipe 4, one end of the air washing pipe is fixedly connected with the top of the box body 1, and an air washing box 2 is fixedly connected to the top of the box body 1, and the other end of the air washing pipe passes through the inside of the air washing box 2, and the top of the air washing box 2 is fixedly connected with a liquid injection pipe, and the side of the air washing box 2 away from the air washing pipe is fixedly connected with an air outlet pipe, and an atomizing adsorption mechanism is arranged on the air washing box 2, and a burner 3 is arranged on the other side of the box body 1, and a door body is connected to one side of the burner 3 9, a control panel 10 is installed at one end of the door body 9, and an air inlet 8 is installed at one end of the burner 3, a filter screen 13 is provided at the end of the burner 3 close to the air inlet 8, and a combustion chamber is installed at the end of the burner 3 away from the air inlet 8, the interior of the combustion chamber is evenly filled with natural gas 16, and a burner 5 is installed at the top of the combustion chamber, the burner 5 passes through the top of the burner 3, the other end of the burner 3 is connected to the box body 1 through an air duct 6, and an exhaust fan 7 is installed on the air duct 6.
[0022] It should be noted that, since existing catalytic combustion equipment usually directly transports exhaust gas into the interior, and since the equipment lacks a mechanism for effectively preheating the exhaust gas, it takes a lot of time to heat the exhaust gas when it enters the catalytic combustion equipment, resulting in a very slow combustion rate, which affects the catalytic efficiency of the equipment. Therefore, in order to solve the problem that existing catalytic combustion equipment lacks a mechanism for effectively preheating the exhaust gas, which makes it take a lot of time to heat the exhaust gas and the combustion rate is very slow, the present solution is to provide a burner 3 to effectively preheat the exhaust gas in the box 1, thereby reducing the heating time required for the exhaust gas to enter the equipment, thereby improving the catalytic efficiency of the equipment.
[0023] Specifically, in this embodiment, the scheme mainly provides a burner 3 to effectively preheat the exhaust gas in the box 1, reducing the heating time required for the exhaust gas to enter the device, thereby improving the catalytic efficiency of the device. By turning on the power, fresh air enters the burner 3 from the air inlet 8, firstly filtered out impurities and dust by the filter 13, and then enters the combustion chamber, mixed with the internal natural gas 16, and ignited by the burner 5. Since the main component of natural gas is CH4, CO2 and H2O are generated after full combustion, so the exhaust gas does not pollute the atmosphere. It is a clean energy source that is beneficial to environmental protection. At the same time, natural gas 16 is used to directly burn air for heating, and the circulating air is heated with very little energy loss. Natural gas can be used as a heating source, which solves the problem that high-power electricity consumption cannot be used in certain occasions. The ceramic heat storage rod 15 makes it easy to store excess heat and release it when the heat is insufficient to achieve a continuous supply of heat. After that, the hot air is drawn into the box body 1 by the exhaust fan 7. The burner 3 can effectively preheat the exhaust gas and reduce the heating time required for the exhaust gas to enter the equipment, thereby improving the catalytic efficiency of the equipment.

[0025] In this embodiment, the slider and the slide rail 12 are provided to limit the position of the slider, provide a moving track for the slider, and make the slider run more smoothly.
[0026] In a further preferred embodiment of the present invention, Figure 1-3 As shown, an adsorption fixing mechanism 14 is provided between the filter 13 and the burner 3 to facilitate the removal and installation of the filter 13 .
[0027] In this embodiment, by pulling the filter 13 outward with force, the positioning rod 141 can be disengaged from the positioning cylinder 142 and then slide out from the slide rail 12, so that the filter 13 can be disassembled and cleaned after excessive impurities are absorbed on it after long-term use.
[0028] In a further preferred embodiment of the present invention, Figure 2-3 As shown, ceramic heat storage rods 15 are installed at both ends of the combustion chamber, and the ceramic heat storage rods 15 are symmetrically distributed up and down with respect to the natural gas 16.
[0029] In this embodiment, the ceramic heat storage rod 15 is provided to facilitate storage of excess heat in the heat storage rod and release it when the heat is insufficient, thereby achieving continuous supply of heat.

The observation window 11 and the door body 9 are welded into an integrated structure, and a handle is installed on the door body 9 on one side of the observation window 11.
[0031] In this embodiment, the airtightness of the device is ensured by setting, and the observation window 11 can be used to observe the internal situation.
