Claim:
1. An apparatus for producing a water-absorbent resin, comprising: a polymerization reactor in which a polymerization product is produced by polymerization reaction of a water soluble ethylenically unsaturated monomer in a liquid medium, the polymerization reactor including a first channel portion having a first channel which is connected to the reactor main body gas discharging portion and through which the gas discharged from the reactor main body by the reactor main body gas discharging portion flows; a first channel portion temperature adjusting portion which adjusts a temperature of the first channel portion to fall within a predetermined temperature range in which the gas flowing through the first channel of the first channel portion is not condensed; a first cooler which cools the gas of the gaseous phase portion from the reactor main body, the first cooler including a second channel portion which is connected to the first cooled fluid discharging portion and has a second channel through which the first cooled fluid discharged from the first cooler main body by the first cooled fluid discharging portion flows toward the reactor main body; a polymerization reactor temperature adjusting portion which adjusts a temperature of the reactor main body to fall within a predetermined temperature range in which the gas of the gaseous phase portion in the reactor main body is not condensed; a third channel portion which is connected to the reactor main body liquid discharging portion and has a third channel through which the liquid discharged from the reactor main body by the reactor main body liquid discharging portion flows; a concentrator which concentrates the polymerization product, the concentrator including a concentrator adjusting portion which adjusts a temperature of the concentrator main body upper portion to fall within a predetermined temperature range in which gas of the gaseous phase portion within the concentrator is not condensed.
