Description

Technical Field

[0001] This utility model relates to the field of combustion heating equipment, specifically to a reverse burner. Background Technology

[0002] Methanol has a wide range of sources and mature production processes. It mainly comes from coal chemical industry and natural gas synthesis. It can be produced using coal, natural gas, coalbed methane, biomass, etc. Under high temperature and sufficient air conditions, methanol can be completely burned to produce carbon dioxide and water. However, methanol combustion can also produce pollutants such as formaldehyde and nitrogen oxides, which require further purification treatment.

[0003] The carbon dioxide produced will sink to the bottom compared to air. If the produced carbon dioxide in an existing burner prevents the combustion of oxygen, it will cause the burner to malfunction or burn incompletely. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a reverse burner that can achieve reverse combustion and heating effect.

[0005] The objective of this utility model is achieved through the following technical measures:

[0006] A reverse burner, characterized in that: it includes a heating cylinder, two fixed mounting plates are fixedly connected to the heating cylinder, a combustion assembly is connected to the heating cylinder, an air inlet pipe is connected to the combustion assembly, the combustion assembly includes a combustion sleeve, the combustion sleeve is fixedly connected to the upper surface of the heating cylinder, the combustion sleeve is fixedly connected to the lower surface of the air inlet pipe, a plurality of combustion gas pipes are arranged inside the combustion sleeve, the plurality of combustion gas pipes are fixedly connected to each other by connecting bends, a plurality of combustion nozzles are fixedly connected to the combustion gas pipes, the plurality of combustion nozzles are evenly distributed on the combustion gas pipes, the plurality of combustion nozzles are oriented towards the heating cylinder, and an exhaust pipe is fixedly connected to the bottom of the heating cylinder.

[0007] As an improvement: an intake pipe is fixedly connected to the input end of the combustion gas pipe at one edge, and an intake flange is fixedly connected to the input end of the intake pipe.

[0008] As an improvement: the heating cylinder is provided with a reverse combustion chamber and a heating chamber, which are connected to each other.

[0009] As an improvement, an observation window is provided on the heating cylinder, and the observation window is connected to the reverse combustion chamber.

[0010] As an improvement, each of the fixed mounting plates is fixedly connected with four mounting bolts for fixed installation with the outside.

[0011] As an improvement: a baffle plate is fixedly connected between the combustion sleeve and the air inlet pipe, and multiple air guide holes are opened on the baffle plate, which are evenly distributed on the baffle plate.

[0012] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] The combustion gas pipe ensures the efficient delivery of combustion gases, while the combustion nozzles ignite and eject the flames. The downward-facing combustion nozzles on the combustion gas pipe enable reverse combustion. An air inlet pipe blows air in, which, after passing through a baffle, exits through the air guide holes, increasing wind speed and pressure to ensure combustion stability and heat transfer. This allows the generated heat to be drawn into the heating cylinder, heating both the reverse combustion chamber and the heating chamber within. Exhaust gases and unburned gases are discharged through the exhaust pipe. Attached Figure Description

[0019] Example: Figures 1 to 4As shown, a reverse burner includes a heating cylinder 3, with two fixed mounting plates 8 fixedly connected to the heating cylinder 3. A combustion assembly 2 is connected to the heating cylinder 3, and an air inlet pipe 1 is connected to the combustion assembly 2. The combustion assembly 2 includes a combustion sleeve 21, which is fixedly connected to the upper surface of the heating cylinder 3 and the lower surface of the air inlet pipe 1. Multiple combustion gas pipes 24 are disposed inside the combustion sleeve 21, and the multiple combustion gas pipes 24 are fixedly connected to each other by connecting bends 25. Multiple combustion nozzles 26 are fixedly connected to the combustion gas pipes 24, and the multiple combustion nozzles 26 are evenly distributed on the combustion gas pipes 24, with the direction of the multiple combustion nozzles 26 facing the heating cylinder 3. An exhaust pipe 6 is fixedly connected to the bottom of the heating cylinder 3.

[0020] The combustion gas pipe 24 is used to deliver the gas to the combustion nozzle 26. The combustion nozzle 26 is set downward so that the flame burns downward. When the flame burns in reverse, the heat generated will be output downward, thus achieving the reverse combustion effect. The connecting bend 25 is set at intervals between multiple combustion gas pipes 24, so as to ensure sufficient gas supply to multiple combustion gas pipes 24. The exhaust gas generated by combustion can be discharged to the outside through the exhaust pipe 6.

[0021] The air inlet duct 1 allows a fan to blow air into the heating cylinder 3. This air contains oxygen, ensuring the proper combustion of the flame emitted from the combustion nozzle 26 in the combustion assembly 2. The flowing air also carries the heat generated by the combustion from the combustion nozzle 26 into the heating cylinder 3, achieving a heating effect. Unburned gases and exhaust gases are carried by the flowing air and discharged through the exhaust pipe 6.

[0022] An air inlet pipe 22 is fixedly connected to the input end of the combustion gas pipe 24 at one edge, and an air inlet flange 23 is fixedly connected to the input end of the air inlet pipe 22. The air inlet pipe 22 can be used to supply gas to the combustion gas pipe 24, thereby ensuring the stability of the gas supply and the smoothness of the combustion state. The air inlet flange 23 can better connect and fix with the external gas supply pipe, ensuring the installation stability and sealing of the gas supply pipe.

[0023] The heating cylinder 3 is provided with a reverse combustion chamber 4 and a heating chamber 5, which are connected to each other. The reverse combustion chamber 4 is conical, and the conical structure of the reverse combustion chamber 4 can better transfer heat radiation to the heating chamber 5, ensuring the heating efficiency in the heating chamber 5.

[0024] The heating cylinder 3 is provided with an observation window 7, which is connected to the reverse combustion chamber 4. The observation window 7 allows for effective observation of the combustion state of the flame emitted by the combustion nozzle 26 in the reverse combustion chamber 4, facilitating equipment adjustment and observation of whether maintenance is required.

[0025] Each of the fixed mounting plates 8 is fixedly connected with four mounting bolts 9 for fixed installation with the outside environment. The mounting bolts 9 facilitate the connection and fixation of the fixed mounting plate 8 with the outside environment, ensuring the stability of the entire device in use.

[0026] A baffle plate 27 is fixedly connected between the combustion sleeve 21 and the air inlet pipe 1. The baffle plate 27 has multiple air guide holes 28 evenly distributed on it. The air guide holes 28 on the baffle plate 27 increase the pressure of the incoming air, thereby ensuring complete combustion and effective heat transfer.

[0027] Working principle: Air is blown into the heating cylinder 3 through the air inlet pipe 1. The air inlet flange 23 connects to the external air supply pipe. Combustion gas enters the combustion gas pipe 24 through the air inlet pipe 22. Multiple combustion gas pipes 24 are connected by connecting bends 25. The combustion gas is ignited after being ejected through the combustion nozzle 26 to generate heat. The heat generated by the flame ejected by the air blown in through the air inlet pipe 1 drives the combustion nozzle 26 to eject the flame. After being radiated and expanded through the reverse combustion chamber 4, it enters the heating chamber 5 to achieve the heating effect. The generated exhaust gas and unburned gas are discharged through the exhaust pipe 6.
