Tourmaline treatment device and cooling water circulation system including same

A tourmaline treatment device provided in a circulation path of cooling water, the tourmaline treatment device comprising:

• a housing having an inflow port and an outflow port for cooling water, the outflow port being below the inflow port;
• and
• a container disposed in the housing so as to partition the inside of the housing into an upstream space and a downstream space and contain tourmaline granules,
• the container including an upstream partition wall facing the upstream space and a downstream partition wall facing the downstream space, each of the upstream partition wall and the downstream partition wall being vertically positioned,
• the upstream partition wall being provided with a plurality of inflow holes for introducing cooling water into the container from the upstream space,
• the downstream partition wall being provided with a plurality of outflow holes for allowing cooling water to flow out from the container into the downstream space,
• wherein the container is structured and arranged to increase flow velocity of cooling water passing through the inside of the container, and
• wherein the container is structured to increase the flow velocity by setting an opening rate of the plurality of inflow holes with respect to the upstream side partition wall to be smaller than an opening rate of the plurality of outflow holes with respect to the downstream side partition wall.
