Technical Field
[0001] This utility model relates to the field of heat recovery technology, and in particular to a boiler room temperature raising device based on low-grade energy heat recovery and utilization. Background Technology
[0002] Boiler plant buildings are industrial buildings used for the installation and operation of boilers and their auxiliary equipment. Their design must take into account equipment installation, safe operation, inspection and maintenance, and environmental protection requirements.
[0003] The main building of the thermal power boiler has a high ceiling, causing hot air to rise. Furthermore, the boiler building doors are frequently opened and closed, resulting in low temperatures inside during winter. Additionally, the process equipment and pipelines within the main boiler building primarily contain water, which is unsuitable for operation in low-temperature environments. To prevent freezing and blockage during winter operation, numerous water-based and steam-based heating systems have been installed, significantly increasing the overall operating costs of the unit. The ash water produced by Shell's gasification ash water system has a high temperature and requires cooling. Using circulating cooling water for this purpose would drastically increase Shell's operating costs, contradicting modern industrial development principles.
[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the medium in the boiler plant pipeline is mainly water, which is cold and will freeze. Most of them are equipped with other devices to heat the pipeline. However, the temperature of the ash water in the Shell unit is high and needs to be cooled. Most of them are cooled by circulating water to ensure that both can operate normally. However, all of them rely on the installation of other equipment to ensure their normal operation, which increases the operating costs of enterprises. Utility Model Content

[0010] Preferably, the input end of the conveying pipe is fixedly connected to a reducer, and the input end of the reducer is fixedly connected to the output end of the main conveying pipe, wherein the diameter of the main conveying pipe is larger than the diameter of the conveying pipe.

[0011] Preferably, valves are installed on both the conveying pipe and the conveying branch pipe, and the conveying branch pipe is configured as a C-shape; This is used to allow operators to open or close the corresponding valves to transport grey water from the designated pipeline.

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0017] Reference Figures 1 to 6 As shown, this utility model provides a technical solution: a boiler room temperature raising device based on low-grade heat recovery and utilization, including a recovery component 1, an extraction component 2 installed at one end of the recovery component 1, and a sewage discharge component 3 installed on both the recovery component 1 and the extraction component 2; the recovery component 1 includes a conveying main pipe 11, a cooling main pipe 12 fixedly connected to one side of the conveying main pipe 11, a cooling branch pipe 13 installed on the cooling main pipe 12, and a heater fan 14 installed on the cooling branch pipe 13; the extraction component 2 includes a conveying pipe 22, which is located at the output end of the conveying main pipe 11, a conveying branch pipe 23 fixedly connected to one side of the conveying pipe 22, and a water pump 24 installed on both the conveying pipe 22 and the conveying branch pipe 23.
[0018] The input end of the main conveying pipe 11 is connected to the ash water pipe of the Shell gasification system. The ash water requiring cooling is conveyed to the cooling main pipe 12 through the main conveying pipe 11. The cooling main pipe 12 is located in the boiler room. By setting up multiple sets of cooling branch pipes 13, the heat dissipation area of the ash water can be effectively increased. Furthermore, because a heater 14 is installed on the cooling branch pipe 13, the airflow velocity at the cooling branch pipe 13 can be effectively accelerated, thereby achieving the cooling operation of the ash water in the cooling branch pipe 13. Under the operation of the heater 14, the heat will be evenly distributed to the... Inside the boiler room, the entire boiler room is heated. After cooling, the ash water re-enters the main conveying pipe 11 and, with the help of the water pump 24, conveys the ash water in the main conveying pipe 11 to the conveying pipe 22. Through the conveying pipe 22, the treated ash water is re-transported to the Shell gasification system for continued use. Operators can control the flow of ash water by opening and closing corresponding valves according to actual usage. In actual installation, installers will also install monitoring instruments and meters to monitor the entire device in real time to ensure it is functioning properly.
[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, this utility model provides a technical solution: a boiler room temperature raising device based on low-grade heat recovery and utilization. Valves are installed on both the main conveying pipe 11 and the main cooling pipe 12. The main cooling pipe 12 and the cooling branch pipe 13 are fixedly installed together by flanges and bolts / nuts. A protective cover 141 is installed on the heater 14. An installation ring A142 is fixedly connected to the bottom surface of the heater 14. An installation ring B143 is provided below the installation ring A142. The heater 14 is installed on the cooling branch pipe 13 by bolts / nuts using the installation rings A142 and B143. Protective gaskets 144 are fixedly connected to the inner surfaces of the installation rings A142 and B143. A filter cylinder 15 is installed inside the cooling branch pipe 13. An installation plate 151 is fixedly connected to one end of the filter cylinder 15. An installation hole 152 is opened on the installation plate 151, and the installation hole 152 corresponds to the hole on the flange of the cooling branch pipe 13.
[0020] By installing valves on the main conveying pipe 11 and the main cooling pipe 12, operators can control the flow direction of the grey water by opening and closing the corresponding valves. Then, by setting installation rings A142 and B143, operators can easily install the heater 14 onto the cooling branch pipe 13. Because of the protective pad 144, the installation rings A142 and B143 will not directly contact the cooling branch pipe 13, preventing damage to the cooling branch pipe 13. The protective pad 144 is made of high-temperature resistant material. At the same time, because a filter cartridge 15 is installed in the cooling branch pipe 13, impurities in the grey water can be filtered to prevent impurities from damaging the blades of the water pump 24.
[0021] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a boiler room temperature raising device based on low-grade heat recovery and utilization. The input end of the conveying pipe 22 is fixedly connected to a reducer 21, and the input end of the reducer 21 is fixedly connected to the output end of the conveying main pipe 11. The diameter of the conveying main pipe 11 is larger than the diameter of the conveying pipe 22. Valves are installed on both the conveying pipe 22 and the conveying branch pipe 23. The conveying branch pipe 23 is C-shaped. The sewage discharge component 3 includes a sewage discharge pipe 31. Two sets of sewage discharge pipes 31 are provided. One set of sewage discharge pipes 31 is installed on the conveying main pipe 11, and the other set of sewage discharge pipes 31 is installed on the conveying pipe 22. Sewage discharge valves 32 are installed on both sets of sewage discharge pipes 31.
[0022] By setting the reducer 21, the cooled ash water will be accelerated after entering the conveying pipe 22. By accelerating the ash water, its residence time in the conveying pipe 22 and the conveying branch pipe 23 will be reduced, thereby reducing the risk of impurities in the ash water clogging the conveying pipe 22 and the conveying branch pipe 23. In addition, the operator can control the opening or closing of the drain pipe 31 by opening or closing the drain valve 32, and perform sewage discharge operation on the main conveying pipe 11 and the conveying pipe 22 through the drain pipe 31.
[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
