The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] 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.

[0022] The utility model embodiment provides a gasification furnace burner water cooling structure, such asFigures 1-4 As shown, the water cooling structure of the gasifier burner includes: a liquid storage tank 1 for storing water coolant; a protective shell 8 installed on one side of the liquid storage tank 1, with a pressure pump provided inside the protective shell 8. The liquid discharge end of the pressure pump is equipped with a liquid discharge pipe 9, and a heat exchanger 10 is sleeved on the liquid discharge pipe 9. The heat exchanger 10 is sleeved outside the gasifier burner; a liquid replenishing pipe 12 fixed to the liquid inlet end of the pressure pump, and the liquid replenishing pipe 12 extends into the liquid storage tank 1; a pressure relief valve 7 provided at the top of the liquid storage tank 1 for discharging the water vapor pressure, and a pressure gauge is provided on the pressure relief valve 7; a return pipe 11 installed on the heat exchanger 10, and the return pipe 11 is communicated with the liquid storage tank 1; a liquid replenishing assembly installed at the top of the liquid storage tank 1 for replenishing the water coolant at any time.

[0023] In this embodiment, the liquid storage tank 1 serves as the core water storage component of the entire cooling system, storing sufficient water coolant to ensure the continuous progress of the burner cooling process. The protective shell 8 provides a safe operating environment for the pressure pump, preventing it from being directly exposed to high-temperature or corrosive environments, reducing equipment damage and the risk of electric leakage. The pressure pump is responsible for pressurizing the water coolant in the liquid storage tank 1 and transporting it to the heat exchanger 10, enhancing the cooling effect. The heat exchanger 10 effectively absorbs the heat generated by the burner through the heat exchange principle to achieve the cooling purpose. The pressure relief valve 7 is used to discharge the excessive pressure generated by the accumulation of water vapor to protect the safety of the equipment, and the pressure gauge monitors the internal pressure of the liquid storage tank 1 in real time, providing accurate data support for the staff to facilitate timely adjustment and maintenance. The return pipe 11 redirects the water coolant after heat exchange back to the liquid storage tank 1 to form a closed-loop circulation system. This design not only saves water resources but also improves the cooling efficiency and reduces energy consumption.

[0024] In a further preferred embodiment of the present invention, the liquid replenishing assembly includes a support frame 4 fixed to the top of the liquid storage tank 1; a liquid replenishing tank 5 movably installed inside the support frame 4, and the liquid replenishing tank 5 is used to store low-temperature water coolant. A fixed cylinder 3 is installed at the bottom of the liquid replenishing tank 5, and a connecting cylinder 2 is detachably installed inside the fixed cylinder 3. The connecting cylinder 2 is arranged at the top of the liquid storage tank 1; limiting handles 6 are provided on both sides of the liquid replenishing tank 5, and both of the limiting handles 6 are in contact with the top of the support frame 4; a monitoring assembly is provided inside the liquid replenishing tank 5 for monitoring the water level.

[0025] In this embodiment, the support frame 4 provides a stable installation platform for the liquid replenishing tank 5, thus ensuring the accuracy and safety of water replenishment. The liquid replenishing tank 5 is specifically used for storing low-temperature water coolant. This design allows for quick and convenient replacement or replenishment of the coolant when needed. When the coolant in the liquid replenishing tank 5 is exhausted, simply disassemble the connecting cylinder 2 to replace the new liquid replenishing tank 5. The limiting handles 6 provided on both sides of the liquid replenishing tank 5 not only facilitate the staff to carry and move the liquid replenishing tank 5 but also play a limiting role. The monitoring component is used to monitor the water level of the coolant in real time. This design enables the staff to always know the remaining amount of the coolant in the liquid replenishing tank 5 and make timely decisions on replenishment or replacement.

[0026] In a further preferred embodiment of the present utility model, the monitoring component includes a mounting frame 17, a connecting rod 18, a floating ball 19, a contact plate 20, and a trigger button 21. The mounting frame 17 is fixed on the inner wall of one side of the liquid replenishing tank 5. The connecting rod 18 is movably installed on the mounting frame 17. The floating ball 19 and the contact plate 20 are respectively installed at the bottom and top of the connecting rod 18. The trigger button 21 is arranged on the inner wall of the top of the mounting frame 17, and the contact plate 20 can contact the trigger button 21.

[0027] In this embodiment, the connecting rod 18 is one of the core components of the monitoring component. It is responsible for connecting the floating ball 19 and the contact plate 20 to form an integral water level sensing unit. The connecting rod 18 can slide freely within the mounting frame 17 and move up and down according to the change of the coolant water level in the liquid replenishing tank 5. The floating ball 19 is used to directly contact the coolant and float up and down according to the change of the water level. The contact plate 20 makes contact with or separates from the trigger button 21. When it contacts the trigger button 21, it will trigger a corresponding signal output (such as an electrical signal or a mechanical signal) to indicate the water level state of the coolant in the liquid replenishing tank 5.

[0028] In a further preferred embodiment of the present utility model, a rubber waterproof protective sleeve is fixedly sleeved outside the trigger button 21. A pressure regulating port is provided at the top of the liquid replenishing tank 5, and a dust-proof net 16 is installed in the pressure regulating port.

[0029] In this embodiment, the rubber waterproof protective sleeve effectively prevents the coolant or other liquids from accidentally splashing into the trigger button 21, avoids equipment failures caused by short circuits or corrosion, reduces the direct contact of the trigger button 21 with a humid environment, and thus extends its service life. The pressure regulating port allows the natural balance of the pressure inside and outside the liquid replenishing tank 5, preventing potential safety hazards caused by excessive pressure differences. The dust-proof net 16 effectively blocks dust, impurities, etc. in the air from entering the inside of the liquid replenishing tank 5, ensuring the cleanliness of the coolant.

[0030] In a further preferred embodiment of the present utility model, two limiting rods 13 are installed in the liquid storage tank 1, and the same support plate 14 is movably sleeved on the two limiting rods 13. A blocking block 15 is installed on the top of the support plate 14. The blocking block 15 is made of foam plastic. A liquid replenishing cylinder is provided at the top of the liquid storage tank 1. The connecting cylinder 2 is installed on the liquid replenishing cylinder. The blocking block 15 can extend into the liquid replenishing cylinder, and the blocking block 15 is used to seal the liquid replenishing cylinder.

[0031] In this embodiment, the support plate 14 provides a stable support platform for the blocking block 15, ensuring that the blocking block 15 will not shake or shift during movement. The limiting rods 13 limit the movement trajectory of the support plate 14, enabling it to move up and down along a predetermined path, improving the reliability and stability of the system. The foam plastic material has the characteristics of light weight and durability, reducing the weight of the blocking block 15 while ensuring its stability and durability during use. At the same time, the foam plastic material has a certain elasticity and sealing property, which can closely fit the inner wall of the liquid replenishing cylinder, effectively preventing the leakage of the coolant. When the water level drops, the blocking block 15 drops away from the liquid replenishing cylinder, and at the same time, it can isolate the reserved coolant to prevent its temperature from rising.

[0032] In a further preferred embodiment of the present utility model, a plurality of mesh holes are provided on the support plate 14. A connecting pipe is provided between the connecting cylinder 2 and the fixed cylinder 3. The connecting pipe is fixed to the bottom of the connecting cylinder 2, and the connecting pipe is rotatably installed on the top of the fixed cylinder 3. The connecting pipe is a metal hose.

[0033] In this embodiment, the mesh holes allow the coolant to flow freely up and down on the support plate 14. As a connecting pipe, the metal hose has good flexibility and bendability, can adapt to angle changes, and ensures a stable connection between the connecting cylinder 2 and the fixed cylinder 3. The detachable and bendable characteristics of the metal hose make the installation and maintenance work more convenient and fast.

[0034] In a further preferred embodiment of the present utility model, a temperature sensor is installed on one side of the liquid storage tank 1, and the detection head of the temperature sensor extends into the liquid storage tank 1. A sewage discharge pipe is provided on one side of the liquid storage tank 1.

[0035] In this embodiment, the temperature sensor can directly monitor the temperature of the coolant, providing important data support for the operating state of the cooling system. Timely monitoring of the coolant temperature helps prevent equipment failures or damages caused by overheating, improving the reliability and service life of the system. The setting of the sewage discharge pipe can discharge the water coolant with a higher temperature to replace the water coolant with a lower temperature.

[0036] In a further preferred embodiment of the present utility model, the protective shell 8 is installed on one side of the liquid storage tank 1 by bolts. The liquid replenishing pipe 12 is made of a metal hose material, and an extension section is provided on the liquid replenishing pipe 12. The extension section is coiled and stored in the protective shell 8.

[0037] In this embodiment, the protective shell 8 is installed on one side of the liquid storage tank 1 by bolts, providing a protective space for the liquid replenishing pipe 12 and its extension section. The extension section can be coiled and stored in the protective shell 8 when not in use, preventing the movement of the protective shell 8 from being affected by the connection of the liquid replenishing pipe 12 when the protective shell 8 is disassembled.

[0038] In summary, compared with the related technologies, by installing a temperature sensor, the present device realizes the real-time monitoring and intelligent regulation of the coolant temperature, effectively preventing equipment failures caused by overheating, improving the safety and reliability of the system. The setting of the sewage pipe and the detachable protective shell 8 simplifies the cleaning work of the liquid storage tank 1 and the pipelines, making the maintenance process more convenient and efficient, improving the work efficiency. By arranging a monitoring component in the liquid replenishing tank 5, the water level can be monitored at all times for timely water replenishment, eliminating the need for manual monitoring and being more labor-saving. By setting the plug 15, the liquid replenishing tank 5 and the liquid storage tank 1 can be isolated, reducing heat transfer and preventing the environmental temperature of the monitoring component from being too high to affect its normal use.

[0039] In several embodiments provided by the present application, it should be understood that the disclosed device can be implemented in other ways.
