The first connecting pipe 6 is provided at one end of the connecting box body 5, the second connecting pipe 7 is provided at the other end of the connecting box body 5, and a heat exchange auxiliary component is provided in the connecting box body 5.

[0031] Before the heat exchange work is carried out through the provided heat exchange tube 4, the incoming gas first passes through the heat exchange auxiliary component for impurity filtration and a preheating exchange work, which helps improve the efficiency of the subsequent heat exchange work, thereby facilitating the improvement of the working efficiency of the heat exchange device 1 and reducing energy consumption; the liquid is input through the liquid inlet pipe 803, passes through the connecting vertical pipe 805 and the connecting horizontal pipe 806 arranged inside the connecting box body 5, and then flows out through the liquid outlet pipe 804. During this process, a preheating exchange effect is provided for the incoming gas. That is, the heat exchange auxiliary component includes a mounting carrier plate 801, a handle 802, a liquid inlet pipe 803, a liquid outlet pipe 804, a connecting vertical pipe 805, a connecting horizontal pipe 806, an extending convex pipe 807 and auxiliary fittings; a placement notch is provided at the top of the connecting box body 5, the mounting carrier plate 801 is adaptively stuck in the placement notch, and the mounting carrier plate 801 is fixed by bolts. A handle 802 is fixedly arranged on the mounting carrier plate 801. A liquid inlet pipe 803 is arranged on one side of the mounting carrier plate 801, and a liquid outlet pipe 804 is arranged on the other side. Both the liquid outlet pipe 804 and the liquid inlet pipe 803 are connected to the connecting vertical pipe 805; there are two groups of connecting vertical pipes 805, and connecting horizontal pipes 806 are equidistantly arranged between the two groups of connecting vertical pipes 805, and the connecting horizontal pipe 806 and the connecting vertical pipe 805 are connected to each other. An extending convex pipe 807 is arranged on the connecting horizontal pipe 806, and the extending convex pipe 807 is connected to the connecting vertical pipe 805, and a connecting thread is arranged at the side wall position of the pipe orifice of the extending convex pipe 807.

[0032] A loading groove cavity is formed between adjacent connecting horizontal pipes 806, and the extending convex pipe 807 is connected to the auxiliary fittings. The auxiliary fittings include a butt joint pipe head 901, a support pipe fitting 902, a frame pipe body 903, a filtering fine net 904 and a connecting piece; the butt joint pipe heads 901 are symmetrically arranged on both sides of the support pipe fitting 902. There are two butt joint pipe heads 901 symmetrically arranged on the support pipe fitting 902. Frame pipe bodies 903 are symmetrically arranged at both ends of the support pipe fitting 902, and a filtering fine net 904 is arranged inside the frame pipe body 903; the filtering fine net 904 is formed by the cross arrangement of thin pipes, and the thin pipes are connected to each other. The filtering fine net 904 is connected to the frame pipe body 903, and there are two frame pipe bodies 903 symmetrically arranged at both ends of the support pipe fitting 902, and the frame pipe body 903 and the support pipe fitting 902 are also connected to each other; the frame pipe body 903 is placed in the loading groove cavity formed by adjacent connecting horizontal pipes 806. That is, two frame pipe bodies 903 and two filtering fine nets 904 are arranged in one loading groove cavity. The filtering fine net 904 arranged in the loading groove cavity has a filtering effect on the impurities in the gas, avoiding excessive adhesion of the impurities in the gas on the heat exchange tube 4 and affecting its heat exchange work. And there will also be liquid flowing in the filtering fine net 904, which has a corresponding auxiliary effect on its heat exchange work on the basis of providing the filtering work.

[0033] This solution also makes the fine filter network 904 detachable by means of the provided connecting piece. That is, a connecting thread is provided on the outer side wall of the pipe orifice of the butt joint pipe head 901, a connecting piece is provided on the butt joint pipe head 901, and the butt joint pipe head 901 and the extending convex pipe 807 are fixedly connected by means of the connecting piece. Moreover, the butt joint pipe head 901 and the extending convex pipe 807 are arranged in corresponding positions and have the same number of sets; the connecting piece includes an outer pipe 1001, a limit card slot 1002, an internally threaded rubber sleeve 1003, and a limit card strip 1004; the inner side wall of the outer pipe 1001 is equidistantly provided with limit card slots 1002, the outer side wall of the internally threaded rubber sleeve 1003 is fixedly provided with limit card strips 1004 equidistantly, the limit card strips 1004 and the limit card slots 1002 are arranged in corresponding positions and have the same number of sets, and the two are adaptively clamped; the internally threaded rubber sleeve 1003 is threadedly connected to the butt joint pipe head 901; when installing the fine filter network 904, place the fine filter network 904 in the loading cavity, and align the butt joint pipe head 901 on the support pipe fitting 902 with the extending convex pipe 807 on the communicating horizontal pipe 806. Then, rotate the outer pipe 1001 so that the internally threaded rubber sleeve 1003 inside the outer pipe 1001 rotates to the docking position of the butt joint pipe head 901 and the extending convex pipe 807. The operation is convenient. When it is necessary to disassemble the fine filter network 904, rotate the outer pipe 1001 in the reverse direction so that the internally threaded rubber sleeve 1003 is separated from the docking position of the butt joint pipe head 901 and the extending convex pipe 807.

[0034] Example 2, on the basis of Example 1, please refer to Figure 8, when carrying out the disassembly work of the fine filter network 904, when the connection and fixation between the extending convex pipe 807 and the docking pipe head 901 are released, at this time, the extending convex pipe 807 lacks a corresponding sealing structure, resulting in the liquid in the communicating horizontal pipe 806 flowing out. This solution is to solve by setting a disassembly and assembly auxiliary fitting on the extending convex pipe 807, that is, the disassembly and assembly auxiliary fitting includes a connecting body 1101, a receiving cavity 1102, a sealing cover plate 1103, a regulating screw 1104, an auxiliary knob 1105, an auxiliary bearing 1106 and a blocking block 1107; the connecting body 1101 is arranged in the extending convex pipe 807, and a receiving cavity 1102 is arranged in the connecting body 1101.

The sealing cover plate 1103 is fixed by screws, and a regulating screw 1104 is threadedly connected through the sealing cover plate 1103. One end of the regulating screw 1104 is fixedly provided with an auxiliary knob 1105, and the other end of the regulating screw 1104 is provided with an auxiliary bearing 1106. The auxiliary bearing 1106 is embedded at one end of the blocking block 1107, and the blocking block 1107 is arranged in the receiving cavity 1102. When carrying out the disassembly work of the fine filter network 904, first rotate the regulating screw 1104 through the auxiliary knob 1105, so that the regulating screw 1104 pushes the blocking block 1107 until the blocking block 1107 blocks the extending convex pipe 807, and then the connection between the extending convex pipe 807 and the docking pipe head 901 can be released. The operation is convenient. And when the fine filter network 904 is replaced and installed, then rotate the regulating screw 1104 in the reverse direction to pull the blocking block 1107 back to the original position and release the blocking of the extending convex pipe 807.
