Apparatus for recovering vent steam and drain

Abstract

The present invention relates to an apparatus for recovering re-evaporated steam and condensate, and in particular, to an apparatus for mixing the steam re-evaporated from condensate that is discharged from a heating unit for heating an object to be treated, with high-temperature steam supplied from a boiler, and for resupplying the mixed steam to the heating unit. To this end, the apparatus comprises: a steam recovery unit for recovering the condensate discharged from a heating unit for heating an object to be treated, and the steam re-evaporated from the condensate, and then supplying the recovered re-evaporated steam to a steam pressurizing unit and the recovered condensate to a boiler; and the steam pressurizing for mixing the re-evaporated steam supplied from the steam recovery unit, with high-temperature steam supplied from the boiler and then supplying the mixed steam to the heating unit. Therefore, with a closed circuit, the apparatus can recover the whole quantity of the re-evaporated steam and condensate for use, prevent the release of steam into the air and utilize a latent heat contained in the condensate, thereby improving the efficiency of energy consumption.

Description

technical field [0001] The present invention relates to a reevaporating steam and condensed water recovery device, and more specifically relates to a device that mixes reevaporated evaporating steam from condensed water discharged from a heating part of an object to be heated with high-temperature steam supplied from a boiler. , and then supplied to the re-evaporation steam and condensed water recovery device in the heating part. Background technique [0002] A general steam heating device supplies heating steam to a heating part formed on a heat exchanger, and is connected to a condensate recovery device for discharging condensate generated by heating. [0003] figure 1 It is a structural block diagram of a traditional steam heating device, as shown in the figure, which includes: a boiler 10 for forming high-temperature steam; heating parts 30, 30' for supplying the high-temperature steam generated from the boiler 10 to the treatment object The steam trap 40, 40' is used ...

AI Technical Summary

Problems solved by technology

[0014] However, a steam heating device without a steam trap can transfer condensed water by gravity, but if the part of the steam that is not released is released to the atmosphere, a differential pressure cannot be formed, resulting in a slow thermal cycle.

[0015] Also, when the water supply pump for transferring the condensed water trapped in the water supply tank is activated, there is a problem of causing damage to the water supply pump due to cavitation
