Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating furnace burner technology, and in particular to a cooling protection device for a natural gas heating furnace burner. Background Technology
[0002] In industrial production, natural gas heater burners are one of the essential pieces of equipment used to provide a high-efficiency and stable heat source;
[0003] During prolonged operation or high-load work, burners are prone to damage due to high temperatures. Therefore, effective cooling measures are needed to protect the burners. Currently, the two most common cooling methods are air cooling and coil-type water cooling. Air cooling dissipates heat by forcing airflow, but due to the low specific heat capacity of air, the cooling efficiency is relatively low and cannot achieve a good cooling effect. In contrast, water cooling is considered a more effective cooling method due to its high heat capacity and good heat dissipation performance, especially under high heat load conditions. However, in traditional coil-type water cooling systems, the heat transfer efficiency between the coil and the burner is not high under high-temperature environments, which can easily cause local overheating of the burner, affecting the safety and lifespan of the equipment. Therefore, we propose a burner cooling protection device for natural gas heaters. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies. By optimizing the heat exchange structure, the heat at the burner can be quickly carried away, avoiding local overheating and significantly improving the cooling effect, thus providing a strong guarantee for the safe operation of the equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A burner cooling protection device for a natural gas heater includes a burner body, which is installed inside a cooling pipe. Pipes are arranged alternately on both sides of the cooling pipe, so the cooling pipe and the pipes on both sides are connected to form a cooling chamber. A water inlet assembly is installed in the upper pipe, and a water pumping assembly is installed in the lower pipe. Cooling covers extending into the cooling chamber are installed at the output end of the water inlet assembly and the input end of the water pumping assembly. The upper and lower cooling covers are located near the burner body. The operation of the water inlet assembly and the water pumping assembly drives water to enter the cooling chamber through the upper cooling cover and pumps the water away through the lower cooling cover.
[0007] Furthermore, the burner body is mounted on the natural gas conduit, and the cooling pipe is also mounted on the natural gas conduit.
[0008] Furthermore, the burner body fits into the inner diameter space of the cooling pipe, and the part of the cooling pipe that fits into the burner body is made of a heat-conducting metal material.
[0009] Furthermore, the water inlet assembly and the water pump assembly are equipped with water pumps. The water pump input end of the water inlet assembly is connected to the water inlet of the upper pipe, and the water pump output end of the water pump assembly is connected to the drain outlet of the lower pipe.
[0010] Furthermore, water pipes are installed at both the water pump output end of the water inlet assembly and the water pump input end of the water pumping assembly, and the water pipes are built inside the cooling cover.
[0011] Furthermore, the hollow interior of the cooling cover is connected to the output end of the water inlet assembly and the input end of the water pumping assembly via hollow tubes. The cross-section of the cooling cover is an arc structure, and several connecting holes are equidistantly arranged on the arc surface near the burner body.
[0012] Furthermore, the water pipe consists of a main pipe and several secondary pipes, with the secondary pipes extending into the cooling shroud and having several water holes.
[0013] Furthermore, a water temperature sensor is installed in the cooling chamber, and the water temperature sensor is electrically connected to the water pump.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By optimizing the heat exchange structure, the cooling chamber formed by the cooling pipe and the upper and lower pipes connected to it, together with the water inlet assembly and the water pumping assembly, realizes the circulation of water, effectively removes the heat from the burner, avoids local overheating, and greatly improves the cooling effect.
[0016] Specifically, the design of the cooling shroud allows water to directly contact the area near the burner body. Through the arc structure and several connecting holes, the cold water entering the upper cooling shroud can directly contact the burner, while the lower cooling shroud allows the hot water near the burner to be quickly drawn away, preventing the cold water from being drawn away. This increases the contact and exchange between the water and the burner without the need for water flow, improving heat transfer efficiency and ensuring that the burner operates within a safe temperature range, thus extending the service life of the equipment.
[0017] The water temperature sensor installed in the cooling chamber can monitor the water temperature in real time and adjust the working status of the water pump according to the water temperature, realizing the automatic control of the cooling system, which not only ensures the cooling effect but also saves energy.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1
[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a burner cooling protection device for a natural gas heating furnace. The device mainly includes a burner body 1, which is installed inside a cooling pipe 2. Pipes 3 are arranged vertically on both sides of the cooling pipe 2. These pipes 3 are connected to the cooling pipe 2 and together form a cooling chamber 21.
[0036] The cooling cycle of this device is as follows: a water inlet assembly 4 is installed in the upper part of the cooling chamber 21 through an upper pipe 3, and a water pumping assembly 5 is installed in the lower part through a lower pipe 3. Both the output and input ends of these two assemblies are equipped with cooling covers 6 that extend into the cooling chamber 21. The cooling covers 6 are positioned close to the burner body 1 to ensure effective cooling (sending water to the burner body 1 or pumping away the hot water in the burner body 1).
[0037] Working principle: When the water inlet assembly 4 and the water pumping assembly 5 start working, the water body will be sent into the cooling chamber 21 through the upper cooling cover 6, and then pumped away through the lower cooling cover 6, forming a cooling cycle. Example 2
[0038] like Figure 1-4 As shown, the burner body 1 is mounted on the natural gas conduit 11, and the cooling pipe 2 is mounted on the natural gas conduit 11 to ensure the compactness of the structure.
[0039] The burner body 1 fits into the inner diameter space of the cooling pipe 2. The part of the cooling pipe 2 that contacts the burner body 1 is made of a heat-conducting metal material, such as copper, and is thinned here to help transfer the heat generated by the burner body 1 to the cooling water more effectively.
[0040] The water inlet assembly 4 and the water pumping assembly 5 are equipped with a water pump 7. The input end of the water pump 7 at the water inlet assembly 4 is connected to the water inlet of the upper pipe 3, and the water inlet is connected to the cold water supply. The output end of the water pump 7 at the water pumping assembly 5 is connected to the drain outlet of the lower pipe 3, and the drain outlet can be connected to the natural cooling system.
[0041] The cooling cover 6 is hollow inside and is installed through hollow tubes 61 to the output end of the water inlet assembly 4 and the input end of the water pumping assembly 5 respectively. The cooling cover 6 has a circular cross-section and several connecting holes 62 are equidistantly arranged on the arc surface near the burner body 1, which helps the water to be evenly distributed through or enter.
[0042] Among them, water pipes 8 are installed at the output end of water pump 7 at water inlet component 4 and the input end of water pump 7 at water pumping component 5. The water pipes 8 are built inside the cooling cover 6 to extract water from the arc surface of the cooling cover 6.
[0043] The water pipe 8 consists of a main pipe and several secondary pipes. The main pipe is connected to the water pump 7, and the secondary pipes extend into the cooling shroud 6 and are provided with several water holes 81.
[0044] A water temperature sensor 9 is also installed in the cooling chamber 21. This sensor is electrically connected to the water pump 7. When the water temperature exceeds the preset value, the water temperature sensor 9 will trigger the water pump 7 to accelerate its operation, thereby enhancing the cooling effect and ensuring the safe operation of the equipment.
[0045] The working process of this utility model is as follows: When using a natural gas heater burner cooling protection device, firstly, the water pump 7 of the water inlet assembly 4 and the water pumping assembly 5 is started (by the water temperature sensor 9 detecting the water temperature to open and close). The water pump 7 sends cooling water into the cooling chamber 21 through the upper cooling cover 6. After the cooling water exchanges heat with the burner body 1 in the cooling chamber 21, it is drawn away by the lower cooling cover 6, forming a continuous cooling cycle. At the same time, the water temperature sensor 9 monitors the water temperature in the cooling chamber 21 in real time and adjusts the working state of the water pump 7 as needed to ensure the optimal cooling effect.
[0046] 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.
