Steam heater

The embodiment of the utility model discloses a steam heater. The steam heater comprises a heater body. A steam inlet is formed in the upper end of the heater body, a temperature control valve is arranged at the lower end of the heater body, and a water dividing device is arranged in the heater body. The heater body internally comprises a steam heating layer and a condensate water cooling layer, the steam heating layer is arranged at the upper portion of the heater body, the condensate water cooling layer is arranged at the lower portion of the heater body, and the water dividing device is arranged between the steam heating layer and the condensate water cooling layer. The steam inlet is communicated with the steam heating layer, the condensate water cooling layer comprises a cooling drainage pipe, one end of the cooling drainage pipe is communicated with the water dividing device, and the other end of the cooling drainage pipe is communicated with the temperature control valve. According to the steam heater, the steam heater is divided by the water dividing device into the steam heating layer and the condensate water cooling layer, heating and cooling of steam and steam condensate water can be respectively controlled, segmentation control can be achieved, and pipe damage and the like caused by direct drainage of the high-temperature steam condensate water can be avoided.
