Steam generation apparatus

A steam generation apparatus comprising:

• a vaporizer housing including a cylindrical part having a predetermined diameter and length, axial opposite ends of the vaporizer housing being opened, and collars formed at axial opposite ends of the cylindrical part;
• an upper flange and a lower flange to be joined to respective one of the collars of the vaporizer housing;
• a vaporizer having a cylindrical shape with axial opposite ends being opened, the vaporizer being housed within the cylindrical part of the vaporizer housing with a spiral channel in between;
• at least one exothermic member disposed such that an inside of the vaporizer is heated to a predetermined temperature;
• an injection nozzle located at a center of the upper flange and including an intake for liquid to be treated and a solenoid valve;
• a steam socket that is a member attached to the lower flange for guiding steam produced in the vaporizer to the spiral channel, the steam socket including a steam inlet port connected to an inside of the vaporizer, a steam outlet port connected to the spiral channel, and a steam channel connecting the steam inlet port and the steam outlet port;
• and
• a wastewater discharge port passing through both the lower flange and the steam socket.
