In recent years, the heat of hydrogen engines has increased significantly, the emissions of which are pure water, producing no pollutants, but the cost of hydrogen fuel is too high, and the storage and transportation of hydrogen fuel is technically very difficult because hydrogen molecules are very small and escape very easily through the housing of the storage device.

When the reverse-time impeller set 3 works, the second main shaft 301 is driven to serve as a power output shaft of the water pump 4, the water pump 4 presses water into the pressure cylinder 1 in a working mode of impeller reverse rotation, and the water pump 4 is fixed at the bottom of the pressure cylinder 1. The plurality of impeller units a are sequentially connected to the second main shaft 301.

The impeller unit a includes an impeller A1 and a housing A2, as shown in fig. 4 to 6. The housing A2 includes two flanges a21 and a sleeve a22 sandwiched between the two flanges a 21. All the flange plates A21 on the timing impeller group 2 and the reverse timing impeller group 3 are connected in series through a screw rod 13, and the upper end of the screw rod 13 is connected to the top of the pressure cylinder 1. Specifically, a plurality of threaded holes a23 are provided around the circumferential direction of the flange a21, and a plurality of threaded holes a 13 are provided around the circumferential direction of the flange, the number of threaded holes corresponding to the number of threaded rods.

The sleeve A22 is made of a seamless pipe through machining, an inclined hole is formed in the wall of the sleeve to form an air inlet A3 and an air outlet A4, the impeller A1 is arranged in the sleeve A22, and holes for the first spindle 201 or the second spindle 301 to penetrate through are formed in the flange A21 and the impeller A1. The first main shaft 201 or the second main shaft 301 is connected with the flange A21 through a bearing and fixedly connected with the impeller A1.

High-temperature and high-pressure steam enters the shell A2 from the air inlet A3 to drive the impeller A1 to rotate, so that the first main shaft 201 is driven to rotate, and then the high-temperature and high-pressure steam is thrown out from the air outlet A4 by the rotation inertia of the impeller to enter the next unit.

The heat carried by the water vapor is far higher than that of the water, when the high-temperature water vapor flows through the tube bodies immersed in the water, the heat is dissipated in the water again due to the heat conductivity of the tube bodies, so that the temperature in the cylinder is continuously accumulated, and the water in the cylinder can be heated for the second time.

The water outlet 405 of the water pump 4 is provided with a check valve 12 for preventing the reverse flow of the high temperature and high pressure water.

The shape of the water pump impeller 401 of this embodiment is similar to the impeller A1 of the impeller unit described above, and is also a three-blade impeller, but the radial dimension of the water pump impeller 401 is smaller than the radial dimension of the impeller A1 of the impeller unit of the timing impeller group 2, so as to prevent the excessive inflow caused by the too large size of the water pump impeller, and to keep the balance between the delivered water amount and the evaporation amount of water.

Of course, the water inlet amount of the water pump can be controlled by arranging the speed reducing mechanism at the output end of the second main shaft 301 without changing the size of the impeller of the water pump.

Furthermore, threaded holes are also formed in two water pump flanges 403 of the water pump 4, the lower end of the lead screw 13 extends to the two water pump flanges 403, and the water pump flanges 403 on the water pump 4 and the a21 of the timing impeller group 2 and the counter-timing impeller group 3 are connected in series through the lead screw 13.

When water is pumped from the inside of the pressure cylinder 1, external water flows through the condensation preheater 8 from the water inlet pipe 801 to enter the pressure cylinder 1 from top to bottom, steam is sprayed out from the pressure cylinder 1 and then rises along the condensation preheater 8, and the rising of the steam meets a cold water pipe to be cooled and condensed and is condensed to flow down along the inner wall of the cylinder body to be accumulated at the bottom of the cylinder body.
