[0030] The device described in this invention can not only be installed in the tail flue of a boiler to replace conventional economizers that expand the heating surface, such as bare tubes or spiral finned tubes, but also in the flue gas passage at the boiler outlet to further reduce the boiler exhaust temperature.

[0031] Specific Implementation Method Two: Combining Figures 1 to 3 This embodiment of the invention further includes an electric gate valve 109 for disconnecting the working fluid supply pipeline, a thermocouple 110, and a pressure gauge 111 for the working fluid supply pipeline. The working fluid supply pipeline 101 is equipped with these components on a section near the working fluid outlet.

When the flue gas temperature changes, the water flow rate is automatically adjusted, enabling unattended operation and intelligent regulation. Other components and connections are the same as in the first embodiment.

[0032] Specific implementation method three: Combining Figures 1 to 3 In this embodiment, the number of tube boxes 200 is a positive integer not less than 1. Other components and connections are the same as in specific embodiments one or two.

[0033] Specific implementation method four: Combination Figures 1 to 3 In this embodiment, there is one pipe box 200.

[0034] Specific Implementation Method Five: Combining Figures 1 to 3 This embodiment describes a plurality of pipe boxes 200, which are arranged in series, in parallel or in a combination of series and parallel in the working fluid inlet pipe 105 and the working fluid outlet pipe 106.

[0035] When multiple pipe boxes 200 are arranged in series, the multiple pipe boxes 200 are connected end to end in sequence from the working medium inlet side to the working medium outlet side through multiple pipe box connecting pipes. The working medium inlet of the pipe box 200 near the working medium inlet side is connected to the working medium inlet pipe 105 through the pipe box connecting pipe, and the working medium outlet of the pipe box 200 near the working medium outlet side is connected to the working medium outlet pipe 106 through the pipe box connecting pipe. Each pipe box connecting pipe is equipped with a manual shut-off valve for disconnecting the pipe box connecting pipe.

Each pipe box connecting pipe is equipped with a manual shut-off valve for disconnecting the pipe box connecting pipes. A pipe box inlet pressure gauge is installed on the pipe box connecting pipe near the working fluid inlet pipe 105 at the working fluid side outlet. Other components and connections are the same as in specific implementation methods one, two, three, or four.

[0037] Specific Implementation Method Six: Combination Figures 1 to 3This embodiment further includes a working fluid disconnection system 300, which comprises multiple disconnection bypasses 301 and multiple manual shut-off valves 302 for bypass disconnection.

Each disconnection bypass 301 is equipped with a manual shut-off valve 302. With this configuration, the entire device can be divided into several groups of pipe boxes according to actual conditions, each group forming its own system. The steam and water side is equipped with corrosion-resistant valves, and the flue gas side inlet and outlet are equipped with manual or electric shut-off baffles. Both the steam / water and flue gas sides can be disconnected independently, enabling maintenance without shutting down the unit. This represents a new technical route for deep peak shaving and clean energy utilization. Other components and connections are the same as in specific embodiments one, two, three, four, or five.

[0038] Specific implementation method seven: Combining Figures 1 to 3 This embodiment describes a tube box 200 comprising an inlet manifold 201, an outlet manifold 202, an H-shaped heat exchanger tube assembly 203, an intermediate support tube plate 204, a frame and protective plate 205, and two end support tube plates 206. The inlet and outlet of the H-shaped heat exchanger tube assembly 203 are connected to the inlet manifold 201 and the outlet manifold 202, respectively. The heat exchanger tubes in the H-shaped heat exchanger tube assembly 203 are inserted into the tube holes of the intermediate support tube plate 204 at their middle portions, and the heat exchanger tubes at both ends are inserted into the tube holes of the two end support tube plates 206, respectively. The intermediate support tube plate 204 and the two end support tube plates 206 are all mounted on the frame and protective plate 205. With this configuration, all the above components in the tube box 200 are assembled into a single unit in the workshop and then shipped as a whole. If the overall size of the device exceeds the limit, the device can be designed as multiple independent pipe box structures, which can be assembled on-site. Only the adjacent supporting structures (steel sections) of the pipe boxes need to be sealed by welding, which greatly reduces the amount of on-site welding work. Other components and connections are the same as in specific implementation methods one, two, three, four, five, or six.

[0039] Specific implementation method eight: Combination Figures 1 to 3 This embodiment further includes wear-resistant dummy tubes 207 in the tube box 200. One to two rows of wear-resistant dummy tubes 207 are provided on the windward side of the flue gas-side heating surface. These dummy tubes 207 are installed on the intermediate support tube plate 204 and the two end support tube plates 206. This arrangement, by adding one to two rows of wear-resistant dummy tubes to the windward side of the heating surface, combined with the inherent wear-resistant properties of the heating surface itself, can greatly reduce the wear of the heating surface tubes by the flue gas, improve equipment reliability, and reduce maintenance costs. Other components and connections are the same as in specific embodiments one, two, three, four, five, six, or seven.

[0040] Specific Implementation Method Nine: Combining Figures 1 to 3This embodiment further includes a flue gas baffle 208 in the pipe box 200. The flue gas inlet on the flue gas side is provided with the flue gas baffle 208, which is installed on the frame and the protective plate 205. Other components and connections are the same as in specific embodiments one, two, three, four, five, six, seven, or eight.

[0041] Specific Implementation Method Ten: Combining Figures 1 to 3 This embodiment describes the H-type heat exchange surface tube assembly 203, which includes a double-coil serpentine tube screen and several finned tube groups. The double-coil serpentine tube screen is arranged inside the flue, and multiple finned tube groups are provided on adjacent serpentine tube sections. The finned tube surfaces are perpendicular to the longitudinal direction of the tube sections. This configuration enhances heat exchange. The double H-type finned tubes are made of specially customized "ND steel + external enamel process," combining all the advantages of ND steel and external enamel process. This results in extremely strong resistance to low-temperature sulfuric acid dew point corrosion and chloride ion corrosion, making it particularly suitable for harsh operating conditions such as low temperatures and acidic gases. Other components and connections are the same as in embodiments one, two, three, four, five, six, seven, eight, or nine.

[0042] In this embodiment, the H-type heat exchange surface tube assembly 203 adopts an enhanced heat exchange double H-type finned tube. Its fins are formed by symmetrically welding two steel sheets with a central arc to a bare tube, resulting in a shape resembling the letter "H" from the front, hence the name H-type finned tube. The H-type finned tube uses a flash resistance welding process, resulting in a high weld fusion rate, high weld tensile strength, and excellent heat conduction performance. The specifications and spacing of the enhanced heat exchange fins are determined through a combination of enhanced heat transfer calculations, software simulation, and experimental verification, maximizing the use of the extended heat exchange surface.

[0043] Working principle

[0044] Combination Figures 1 to 3 The working principle of the intelligent regulating energy-saving and consumption-reducing integrated device of this utility model is explained as follows: Taking multiple pipe boxes 200 arranged in a series-parallel combination as an example: Before operation, the electric gate valve 103 for disconnection of the working fluid supply pipeline is closed, and the manual gate valve 102 for disconnection of the working fluid inlet side, the electric valve 107 for disconnection of the working fluid inlet pipeline, the electric valve 108 for disconnection of the working fluid outlet pipeline, the electric gate valve 109 for disconnection of the working fluid supply pipeline, the manual gate valve 104 for disconnection of the working fluid outlet side, the manual shut-off valves for disconnection of the pipe box connecting pipelines on each pipe box, and the manual shut-off valves for disconnection of the bypass 301 on each disconnection bypass are all in the closed state;

[0045] The working fluid enters the working fluid side of each pipe box 200 in sequence through the working fluid supply pipe 101 and the working fluid inlet pipe 105 from the working fluid inlet. After heat exchange with the flue gas side, the working fluid flows out from the working fluid outlet through the working fluid outlet pipe 106 and the working fluid supply pipe 101.

[0046] This invention can be independently split on both the medium side and the flue gas side. If the heated surface is damaged, the damaged part can be split, and maintenance and replacement can be carried out without stopping the machine. Alternatively, it can be used in conjunction with the unit's peak shaving to select some parts for operation. This can be achieved by controlling the opening state of the manual shut-off valve for disconnecting the pipe box on the pipe box connection pipe and the manual shut-off valve 302 for bypass disconnection on the bypass 301.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
