Utility Model Content

[0005] The present invention addresses the technical problem of some waste-to-energy incinerators lacking temperature measurement points above the drying grate in the drying section. This prevents effective monitoring of the drying and ignition conditions of the materials in the drying section, leading to unstable and fluctuating boiler operating conditions. Furthermore, large temperature fluctuations in the combustion zone can accelerate coking of the castable surface, impacting the long-term operation of the boiler unit and reducing the overall economic benefits of the unit.

[0006] In order to solve the above problems, the utility model provides a garbage incineration grate with a temperature monitoring system, including a drying furnace section arranged in the garbage incineration grate, annular holes are symmetrically opened at the left and right ends of the drying furnace section, the inner ends of the annular holes are sleeved with a wall sleeve, the inner end of the wall sleeve is installed with an armored temperature measuring thermocouple, the inner end of the wall sleeve is provided with a sealing filler, the sealing filler is located between the wall sleeve and the armored temperature measuring thermocouple, a sealing sleeve frame is provided on the outside of the drying furnace section, the sealing sleeve frame is located on the outside of the wall sleeve, the end of the sealing sleeve frame away from the drying furnace section is fixedly connected to the front ring, the lower end of the sealing sleeve frame is fixedly connected to the flow control valve port, the lower end of the flow control valve port is installed with a nitrogen bottle, the upper end of the nitrogen bottle is fixedly connected to a connecting outer pipe, and the connecting outer pipe and the flow control valve port are butt-jointed with each other.

[0007] In the above-mentioned waste incineration grate with a temperature monitoring system, this solution inserts an armored temperature measuring thermocouple into a wall bushing above the drying furnace section and places it inside the drying furnace section. A compensation wire is laid to the distributed control terminal to achieve real-time monitoring of the operating conditions of the drying section and the temperature difference between the left and right sides, making it convenient for operators to adjust the boiler operating conditions in a timely manner and improve the overall combustion efficiency of the boiler.

[0008] As a further improvement of the present application, an outer hollow detection sleeve is provided on the outer side of the connecting outer tube, and a gas leakage detector is fixedly connected to the inner end of the outer hollow detection sleeve.

At the same time, when the armored temperature measuring thermocouple is disassembled in the event of a fault, the sealing sleeve frame can be set at the outside of the wall sleeve, and the inert gas in the nitrogen bottle can replace the air in the area around the wall sleeve to discharge the combustible gas. This can reduce the disadvantage of combustible gas leakage and sparks that may injure the staff. When the area outside the wall sleeve is filled with inert gas, the staff can extend their arm through the strip opening in the front ring and extend it into the sealed front cover plate that covers the outside of the front ring to make the inert gas in the sealing sleeve frame more fully covered.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-6 A waste incineration grate with a temperature monitoring system is shown, including a drying furnace section 1 arranged in the waste incineration grate, annular holes 18 are symmetrically opened at the left and right ends of the drying furnace section 1, the inner end of the annular hole 18 is sleeved with a wall sleeve 2, the inner end of the wall sleeve 2 is installed with an armored temperature measuring thermocouple 4, the inner end of the wall sleeve 2 is arranged in a sealing filler 3, the sealing filler 3 is located between the wall sleeve 2 and the armored temperature measuring thermocouple 4, a sealing sleeve frame 5 is provided on the outside of the drying furnace section 1, the sealing sleeve frame 5 is located on the outside of the wall sleeve 2, the end of the sealing sleeve frame 5 away from the drying furnace section 1 is fixedly connected to the front ring 7, the lower end of the sealing sleeve frame 5 is fixedly connected to the flow control valve port 10, the lower end of the flow control valve port 10 is installed with a nitrogen bottle 11, the upper end of the nitrogen bottle 11 is fixedly connected to the connecting outer tube 17, and the connecting outer tube 17 and the flow control valve port 10 are docked with each other.

[0027] Figure 1-6 It is shown that a strip opening 8 is provided at the inner end of the front ring opening 7, and a sealing front cover plate 12 is hinged at the front end of the strip opening 8. The sealing front cover plate 12 and the lower end of the strip opening 8 are engaged with each other. A flexible shielding strip 9 is fixedly connected to the inner end of the strip opening 8, and an auxiliary work surface 6 is fixedly connected to the inner wall of the front ring opening 7. The auxiliary work surface 6 is located at the lower inner side of the front ring opening 7. The armored temperature measuring thermocouple 4 is externally connected to a compensation wire, and the compensation wire is externally connected to a distributed control terminal through a controller.

[0028] Figure 1-6It is shown that the present solution has annular holes 18 at a height of 1.5 meters above the drying furnace section 1, and a wall sleeve 2 is placed in the annular hole 18. The wall sleeve 2 extends one centimeter from the surface of the castable and fifteen centimeters beyond the boiler outer wall steel plate. Finally, the armored temperature measuring thermocouple 4 is inserted into the wall sleeve 2 and placed in the drying furnace section 1, and a compensation wire is laid to the distributed control terminal. After installation, the operating personnel can monitor the upper temperature of the drying furnace section 1 in real time through the D distributed control terminal, and monitor the changes in the working conditions of the drying section and the temperature difference between the left and right sides in real time, so that the operating personnel can adjust the boiler working conditions in time and improve the overall combustion efficiency of the boiler. At the same time, when the armored temperature measuring thermocouple 4 is disassembled during a fault, the armored temperature measuring thermocouple 4 will be removed from the wall sleeve 2, which will destroy its sealing state with the surrounding environment. If combustible gas accumulates around the armored temperature measuring thermocouple 4 in the drying furnace section 1, it may cause combustion when it comes into contact with the outside air, thereby Sparks may injure the staff. Therefore, before starting disassembly, the sealing sleeve frame 5 can be set at the outer side of the wall sleeve 2, and the inert gas in the nitrogen bottle 11 can replace the air in the area around the wall sleeve 2 to discharge the combustible gas. This can reduce the leakage of combustible gas and the generation of sparks to injure the staff. When the area outside the wall sleeve 2 is full of inert gas, the staff can extend their arms through the strip opening 8 in the front ring 7 and extend them into the sealed front cover 12 to cover the outside of the front ring 7, so that the inert gas in the sealing sleeve frame 5 is more fully covered. When manual operation is required, the strip opening 8 is opened, and both hands are passed through the inside and outside of the flexible shielding strip 9. The flexible shielding strip 9 can reduce the drifting speed of the inert gas in the sealing sleeve frame 5. At this time, the staff can use the front ring 7 to assist in disassembling and replacing the armored temperature measuring thermocouple 4, thereby ensuring the safety of the armored temperature measuring thermocouple 4 during disassembly and replacement.

[0029] The second implementation method:

[0030] Figure 7 The figure shows a waste incineration grate with a temperature monitoring system. A detection outer hollow sleeve 13 is provided on the outer side of the connecting outer tube 17. A gas leak detector 15 is fixedly connected to the inner end of the detection outer hollow sleeve 13. An inner sealing ring 16 is fixedly connected to the inner end of the gas leak detector 15. The inner sealing ring 16 cooperates with the connecting outer tube 17. At the same time, when the nitrogen bottle 11 is connected to the bottom of the sealing sleeve frame 5, a detection outer hollow sleeve 13 can also be provided on the outer side of the connecting outer tube 17. The gas leak detector 15 in the detection outer hollow sleeve 13 can detect whether the inert gas in the nitrogen bottle 11 leaks when it is output. The detection effect is better when cooperating with the inner sealing ring 16, which can facilitate the gas input process to be stable and efficient.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
