Impulse turbine and turbine device

A turbine device comprising:

• a housing, a rotating shaft, a shaft support, an impulse turbine and a fluid discharge pipe, wherein
• the housing has a space for allowing the impulse turbine to be rotated therein and includes a pair of fluid inlet and fluid outlet provided on one side and an opposite side of the housing, respectively,
• the fluid outlet communicates with the fluid discharge pipe, the rotating shaft is configured to be axially installed in and rotated about a center of the turbine device,
• the shaft support is formed in a center thereof with a through-hole through which the rotating shaft passes and includes a flange portion coupled to the one side of housing,
• the shaft support is formed in a front thereof with a bearing installation groove and formed in a rear thereof with a bearing accommodation space,
• a front bearing for supporting a front of the rotating shaft is fitted and coupled to the bearing installation groove,
• a rear bearing for supporting a rear of the rotating shaft is fitted and coupled to the bearing accommodation space, thereby supporting the rotating shaft eccentrically from the housing, and
• the impulse turbine is coupled to the rotating shaft and rotated, wherein
• (1) the impulse turbine includes a cylindrical body having an axial hole and a blade unit to surround a periphery of the body,
• (2) the blade unit includes a cylindrical base disposed to surround the periphery of the body, and a plurality of unit blades radially arranged in a line along a periphery of the base,
• (3) each of the unit blades includes an outlet that discharges an injected fluid in a direction different from a fluid injection direction but does not discharge the fluid to other unit blades,
• (4) each of the unit blades includes a groove portion for temporarily accommodating the injected fluid, a bottom portion forming a bottom of the groove portion, a first blocking portion forming a right wall of the groove portion, a second blocking portion forming a left wall of the groove portion, and a third blocking portion forming a front wall and an upper wall of the groove portion,
• (5) the bottom portion has a part closed by the upper wall of the groove portion and a remaining part that is opened,
• (6) the first blocking portion has a length shorter than the second blocking portion, and
• (7) the outlet is positioned adjacent to the first blocking portion.
