[0039] Working principle and process:

[0040] Workers use lifting tools to install multiple waste heat utilization box bodies 1 through the base 9 outside the limit frame 10 at the top of the waste heat utilization box body 1 below for mutual assembly. Then, use tools to assemble the connecting pipe 32 outside the inlets and outlets of two adjacent three-way valves 31, and connect the water inlet pipe 33 to the inlet end of the waste heat utilization of gas power generation. By installing a flue gas waste heat boiler at the end of the exhaust pipe of the gas generator set, use the heat network circulation pump to heat the heating water to an appropriate temperature. At the same time, connect the water outlet pipe 35 to the outlet end of the hot water. When working, control the connection of the multi-layer pipeline assembly 3 through the first solenoid valve 2 and introduce it into the waste heat utilization box body 1 at the top. The waste heat generated by gas power generation enters the interior of the waste heat utilization box body 1 for water heating treatment. The temperature detector 5 detects that the water temperature inside the waste heat utilization box body 1 reaches the target temperature. After heating is completed, close the first solenoid valve 2 at the top, open the first solenoid valve 2 on the second layer for heating. At the same time, open the second solenoid valve 4 at the top, and pump out some of the pre-set temperature hot water that has been heated through the water outlet pipe 35 and the pump inside the aggregation barrel 6, and guide it into the interior of the aggregation barrel 6 for sequential heating operations to ensure continuous supply of hot water and reduce the situation of insufficient hot water utilization temperature or interruption.

[0041] Connect the external pipe 83 to the outside of the riser pipe 82 of the substrate 81. After the connection is completed, control the motor 88 to work, directly drive the driving gear 89 at the end of the main shaft to rotate, engage the external driven gear 86 to drive the docking pipe 87 to screw up along the outside of the riser pipe 82, and dock it into the annular groove of the capping cover 85 outside the external pipe 83 for sealing to enhance the sealing effect. According to the use requirements, connect different riser pipes 82, and extract through the outlet pipe 84 and an external pump for export use.
