[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They 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. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: Heat exchange equipment based on hydrogenation unit, such as Figure 1-Figure 4 As shown, it includes a desalted water tank 1 and a boiler water tank 2. The desalted water tank 1 is connected through a soft water pump 3, a water cooler 4, and a heat exchanger 5. The desalted water tank 1 is connected to the feed end of the soft water pump 3 through a pipeline. The boiler water tank 2 is connected to the discharge end of the heat exchanger 5 through a heat conduction flow pipe 6. The soft water pump 3, the water cooler 4, and the heat exchanger 5 are connected in sequence through pipelines. There are several water coolers 4, and the boiler water tank 2 is connected to the outer boiler.

[0026] When the device is running, first, soft water flows out from the desalted water tank 1, is pressurized by the soft water pump 3, and then circulates through the water cooler 4 and the heat exchanger 5, and is heat-exchanged to 95°C. Finally, it flows into the boiler water tank 2 under the flow guidance of the heat conduction flow pipe 6. Based on the connection between the boiler water tank 2 and the outer boiler, the heat-treated water flows into the boiler, thereby changing the steam boiler water inlet from the original room temperature water to 95°C water inlet, so that the daily steam production reaches 40 tons, the calorific value of natural gas is 8000 kcal / cubic, the specific heat capacity of water is 4.2*103Jkg.℃, and the thermal efficiency of the steam boiler reaches 90%. According to theoretical calculations, about 390 cubic meters of natural gas can be saved every day, the efficiency of the heat exchange system is improved, and the purpose of energy saving is achieved, so that the device has the characteristics of easy implementation and obvious energy-saving effect in actual use.

[0027] like Figure 1-Figure 4 As shown, a furnace guide pipe 7 is installed on the outside of the boiler water tank 2. The furnace guide pipe 7 is connected to the outside boiler and is used to guide the circulation of hot water.

[0028] With the guidance support of the furnace guide tube 7, it is ensured that the water after heat treatment can flow stably into the boiler, further ensuring the stability of the heat exchange efficiency.

[0029] By means of the circulation pressurization of the soft water pump 3 and the heat treatment of the water cooler 4 and the heat exchanger 5, the efficiency of the heat exchange system is improved and the purpose of energy saving is achieved. The number and model of the soft water pump 3, the water cooler 4 and the heat exchanger 5 can be adjusted according to actual needs.

[0030] like Figure 1-Figure 4 As shown, the soft water pump 3 is controlled by frequency conversion, and the soft water pump 3 is used to control the circulation volume and water temperature.

[0031] The water cooler 4 and the heat exchanger 5 are used in combination, and the water cooler 4 and the heat exchanger 5 are used to adjust the temperature of the water flow.

[0032] By frequency conversion controlling the soft water pump 3, the circulation volume and water temperature thereof can be controlled as required, so that the soft water enters the boiler as the saturation temperature feed of the steam boiler.

[0033] Example 2: Heat exchange equipment based on hydrogenation unit, such as Figure 1-Figure 4 As shown, an insulation shell 8 for insulation support is installed on the outside of the heat conduction flow pipe 6, and a circulation pipe 12 in a closed circulation loop is arranged inside the insulation shell 8, and the circulation pipe 12 is distributed in an annular shape inside the insulation shell 8.

[0034] A circulation pipe 12 is connected to a hot gas discharge pipe 11 , which is connected to an air pump 9 for circulation control. A hot gas feed pipe 10 is installed at the feed end of the air pump 9 , and the hot gas discharge pipe 11 is installed at the discharge end of the air pump 9 .

[0035] The air pump 9 is connected to the outer boiler through a hot gas feed pipe 10, and the hot gas feed pipe 10 is used to guide the flow of boiler hot steam.

[0036] Under the control of the air pump 9, and with the support of the hot gas feed pipe 10 and the hot gas discharge pipe 11, part of the hot steam in the boiler can circulate into the multiple circulation pipes 12, thereby achieving the effect of heating the insulation shell 8 and the heat-conducting flow pipe 6, so that the temperature of the heat-conducting flow pipe 6 of the device itself is in a relatively stable state, effectively preventing the change of the water temperature after the internal heat treatment due to the use of the heat of the heat-conducting flow pipe 6 itself, reducing the heat loss generated by the circulation of hot water, and improving the full utilization of resources by the device.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
