Description

Technical Field

[0001] The utility model relates to the technical field of heat recovery, in particular to a steam condensate heat recovery device. Background Art

[0002] The phenomenon of a substance changing from gas to liquid is called condensation, also called liquefaction. The condensation of water vapor has the following characteristics: water vapor under a certain pressure must drop to the condensation temperature corresponding to the pressure before it begins to condense into liquid. This condensation temperature is also the boiling point of the liquid. When the pressure decreases, the condensation temperature decreases accordingly. Conversely, the condensation temperature increases. At the same time, at the condensation temperature, water continuously absorbs heat from water vapor, so water vapor can continuously condense into water and keep the temperature unchanged. Patent No. CN202321944412.1 discloses a cooling water tank heat energy recovery device, including a cooling box, a water supply component, a guide roller and a pressure roller, and also includes a recovery component; the recovery component includes a delivery pump, a delivery pipe, a heat dissipation fin, a heat exchange pipe, a fan and a blowing component, the delivery pump is fixedly connected to the cooling box, the delivery pipe is installed on the delivery pump, the heat dissipation fin is fixedly connected to the delivery pipe, the heat exchange pipe is fixedly connected to the delivery pipe, and the fan is fixedly connected to the heat exchange pipe. The hot water at the bottom of the pre-cooling chamber is delivered to the delivery pipe through the delivery pump, and the heat is transferred to the heat exchange pipe through the heat dissipation fin to heat the air inside the heat exchange pipe. The heated air inside the heat exchange pipe is delivered to the blowing component through the operation of the fan, and the blowing component dries the plastic strip, thereby drying the plastic strip, thereby avoiding heat loss of hot water during the delivery process and improving the heat recovery efficiency.

[0003] The disadvantage of the above-disclosed heat recovery equipment is that it is not possible to more efficiently recover and utilize heat during the change of steam condensate, resulting in the heat flowing out with the steam condensate and being unable to be recovered during use. For this reason, we design a steam condensate heat recovery equipment. Utility Model Content
