Referring to fig. 1, a schematic diagram of a steam generator 100 according to a first embodiment of the present invention is shown. Referring to fig. 1-5, the steam generator 100 includes: a steam generating part 10, wherein the steam generating part 10 is provided with a steam generating space 13, one end of the steam generating part is provided with at least one liquid inlet pipe 11, and the other end of the steam generating part is provided with a steam outlet 12; a superheating part 30, wherein a steam transmission pipe is arranged in the superheating part 30, and one end of the steam transmission pipe is connected with the steam outlet 12; a plurality of heat exchange pipes 50, the heat exchange pipes 50 being uniformly extended along the center of the vapor generation space 13 toward the outer circumference, and the plurality of heat exchange pipes 50 being connected to the superheating part 30; at least one heating assembly 20, at least a portion of the heating assembly 20 being disposed within the vapor-generating space 13.
For example, in the vapor generation part 10, a vapor generation space 13 is provided, and a plurality of heat exchange tubes 50 are provided so as to extend uniformly to the outer periphery along the center of the vapor generation space 13, since the conventional hydrogen generator has the vapor generator 100 disposed outside, the hydrogen generating assembly disposed inside the vapor generator 100, thereby achieving this, but such an arrangement results in a small contact area between the steam generator 100 and the heat exchange pipe 50, resulting in a low vapor generation efficiency and further a reduced hydrogen generation rate, and therefore the present invention provides a vapor generation device having a plurality of heat exchange tubes 50 uniformly extending from the center to the outer periphery of the vapor generation space 13, thereby, water and vapor in the whole vapor generation space 13 can better exchange heat with the heat exchange tube 50, and the result of improving the vapor generation efficiency is achieved; on the other hand, one end of the heat exchange pipe 50 is connected to the superheating portion 30, and the gas heated in the steam generation portion 10 enters the superheating portion 30 after the steam is heated, so that the discharged steam is further heated, and the liquid water contained in the steam is secondarily heated before entering the hydrogen generator, thereby reducing the liquid water contained in the steam.

For example, on one hand, the heat exchange tube 50 is a straight tube, and the straight tube-shaped heat exchange tube 50 can increase the gas flow rate without considering the cost, so that the heat exchange tube 50 can continuously maintain a higher temperature state, thereby improving the production efficiency of steam; on the other hand, the heat exchange tube 50 is a coil tube, which can increase the contact area between the gas and the water, thereby better heating the water and improving the utilization rate of the gas.
Specifically, with reference to fig. 1 and 3, the heating assembly 20 includes: a gas heating assembly 21 and a first electric heating assembly 22. For example, most of the existing gas heating groups are heated by tail gas and waste gas, the tail gas is heated by tail gas generated in a hydrogen generator, and because combustible substances such as hydrogen exist in the tail gas, the tail gas is recycled by a combustion catalyst, but the amount of the tail gas needs to be according to the rate of the tail gas generated by the hydrogen generator, when the rate of the tail gas generated by the hydrogen generator is slow, the rate of steam generation is low, further the rate of hydrogen generation is reduced, so that vicious circle is realized, therefore, the first electric heating assembly 22 needs to be heated when the rate of steam generation is low, so as to increase the rate of steam generation; the exhaust gas heating is gas with heat, most of which is hot gas generated by other devices of the chemical plant, but the amount of the exhaust gas is unstable, and when the exhaust gas is less or the temperature of the exhaust gas is lower, the rate of steam generation is low, so that the first electric heating assembly 22 needs to heat when the rate of steam generation is low so as to increase the rate of steam generation.

Preferably, the heat exchange tubes 50 herein may be as shown in FIG. 2, and the heat exchange tubes 50 of the intermediate portion are arranged to extend uniformly along the center of the vapor generation space 13 toward the outer periphery, but leave a space for installing the first electric heater. For example, the first electric heater is disposed to protrude into the vapor generation space 13, thereby increasing a contact area of the first electric heater and the liquid, and when the first electric heater heats the liquid to the vapor, it can be directly discharged upward, preventing the temperature at the first electric heater from being relatively excessively high.
Preferably, referring to fig. 6, the gas heating assembly 21 further comprises: a first fixing plate 33; at least one first transition piece 34, wherein the first transition piece 34 is arranged at one end of the first fixing plate 33 connected with the heat exchange tube 50; wherein the first transition piece 34 and the heat exchange tube 50 are disposed in one-to-one correspondence.
It should be noted that, the first fixing plate 33 is arranged to connect one end of the heat exchange tube 50, and at least one first transition piece 34 is arranged on the first fixing piece, and the first transition piece 34 and the heat exchange tube 50 are arranged in a one-to-one correspondence manner, which is convenient for fixing the heat exchange tube 50 on one hand; on the other hand, when the heat exchange pipe 50 is provided on the first fixing member, its corresponding heat exchange pipe 50 may be inserted through the at least one first transition piece 34.
Preferably, the overheating part 30 includes: a gas superheating part 31 and an electrically heated superheating part 32; the gas superheating unit 31 is provided between the electric heating superheating unit 32 and the steam generation unit 10.
