"Multiple" means two or more, unless otherwise clearly and specifically defined.

[0027] In the specification and claims of the utility model and the above-mentioned drawings, when an element is referred to as being "fixed on" or "mounted on" or "disposed on" or "connected to" another element, it may be directly or indirectly located on the other element. For example, when an element is referred to as being "connected to" another element, it may be directly or indirectly connected to the other element.

[0028] In addition, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. 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.

[0029] like Figure 1 The utility model provides a temperature-adjustable flue gas cooling device, comprising:

[0030] The cooler body 10 comprises, from top to bottom, a cooler upper cover 11, a plurality of finned tubes 12 and a cooler lower cover 13, wherein the plurality of finned tubes 12 communicate with the cooler upper cover 11 and the cooler lower cover 13, the cooler upper cover 11 is provided with a smoke inlet 14, the cooler lower cover 13 is provided with a smoke outlet 15 and a discharge port 16, and a temperature measuring component is provided at the smoke outlet 15;

[0031] A plurality of fans 20, wherein the plurality of fans 20 are arranged in parallel, and the air outlet direction of each fan 20 is perpendicular to the plurality of fin tubes 12;

[0032] A control platform 30 is connected to the plurality of fans 20 and the temperature measuring component.

[0033] Furthermore, since flue gas usually contains gaseous and solid substances, it is necessary to consider the separation of substances in the two states when designing the cooler, to ensure that solid substances can be collected without clogging the cooler, and to ensure that flue gas passes through the cooling area evenly and effectively to improve the cooling effect. Therefore, in some embodiments, the cooler lower cover 13 is designed to be an inverted cone, the flue gas outlet 15 is arranged on the side of the cooler lower cover 13 close to the top, and the discharge port 16 is arranged at the bottom of the cooler lower cover 13. Such a design can make the flue gas enter the cooler lower cover through the finned tube 12, and the solid substances will naturally settle to the bottom of the cone, and the flue gas will be separated from the side flue gas outlet 15, so as to avoid the solid substances from clogging the flue gas outlet 15, and the solid substances can be better collected and discharged.

[0034] In some embodiments, the discharge port 16 is also provided with a pressure sensor 17 and a valve (not shown), and the pressure sensor 17 and the valve are connected to the control platform 30. The pressure sensor 17 can monitor the pressure change of the discharge port in real time, and upload the pressure value to the control platform 30 to ensure that the discharge process is carried out within a safe and stable pressure range. In addition, in combination with the control platform 30, the pressure sensor 17 can realize linkage control with the automatic opening valve. When the pressure of the discharge port 16 reaches the set value, the valve can be automatically opened to realize the automatic management of the discharge, which not only improves the operating efficiency, but also reduces the risk and cost of manual operation.

[0035] Furthermore, the temperature measuring component is a temperature sensor. In other embodiments, the temperature measuring component may also be an infrared temperature measuring component, which is a non-contact temperature measuring component that calculates the temperature of the object by sensing the infrared radiation emitted by the object being measured.

[0036] Further, the plurality of fans 20 include three fans 20, and the three fans 20 are arranged at equal intervals along the length direction of the fin tube 12. By controlling the connection between the control platform 30 and the fans 20, the speed, air volume and wind direction of the fans can be accurately adjusted based on the temperature of the flue gas to meet the cooling requirements under different working conditions. This precise control can ensure that the flue gas is effectively cooled while avoiding energy waste. In some embodiments, the plurality of fans 20 include two groups of fans 20 relatively arranged on both sides of the plurality of fin tubes 12, each group including three fans 20, and the three fans 20 in the same group are arranged at equal intervals along the length direction of the fin tube 12.

[0037] Furthermore, the plurality of fin tubes 12 include 6 to 8 fin tubes. The design of the fin tubes greatly increases the heat exchange area of ​​the radiator, so that the fluid forms a strong turbulence outside the tube, thereby enhancing convective heat transfer and improving the cooling efficiency.

[0038] Furthermore, a temperature sensor is provided at the smoke inlet 14, and the temperature sensor is connected to the control platform 30, so as to quickly obtain the temperature value of the smoke and adjust the opening quantity of the fan based on the smoke temperature.

[0039] Furthermore, the control platform 30 also includes a display panel, which can intuitively display various data and information, such as real-time parameters such as temperature, pressure, air volume, and the operating status and fault information of the equipment. This enables operators to quickly understand the working conditions of the equipment and facilitates real-time monitoring and adjustment.

[0040] The temperature measuring component equipped in the device of the utility model can monitor the temperature of the flue gas in real time and feed the data back to the control platform. The control platform can automatically or manually adjust the speed of the fan and / or other related parameters according to the real-time monitored temperature data to achieve precise control of the flue gas temperature. Through the adjustment of multiple fans, the air volume can be adjusted according to actual needs to achieve efficient cooling of the flue gas.
