Title:
CONDENSATE WATER AND STEAM RECOVERY/SUPPLY DEVICE OF TRAPLESS STEAM GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/088950
Kind Code:
A1
Abstract:
The present invention relates to a condensate water and steam recovery/supply device of a trapless steam generation system, the device recovering and recycling high-temperature and high-pressure condensate water and steam in a steam generation system such as a closed loop circulation-type steam boiler for heating water, and the objective of the present invention is to recover and recycle the high-temperature and high-pressure condensate water and steam by providing a condensate water collection tank at a low position, without using a trap or discharging the high-temperature and high-pressure steam to the outside. To this end, the present invention comprises: the condensate water collection tank (31) provided so as to recover the condensate water (13) and the steam (22), which are generated from a heat exchanger (4) by heat exchange, through a condensate water recovery pipe (30) by means of gravity; a condensate water suction pipe (32) provided inside the condensate water collection tank and having a plurality of through-holes (32a) at the bottom thereof; a pump (33) provided at an outlet side of the condensate water suction pipe so as to pump the condensate water (13) inside the condensate water collection tank (31); a water level sensing rod (34) provided inside the condensate water collection tank so as to control the driving of the pump (22) according to the level of the condensate water; a condensate water pipe (35) provided at an output end of the pump so as to transfer the pumped condensate water to a make-up water tank or a boiler; a steam-passing pipe (37) provided to communicate with the upper part of the condensate water collection tank (31), and equipped with a first check valve (36); a steam tank (38) provided at a discharge path of the condensate water (13) and at which the steam (22) discharged through the steam-passing pipe (37) is recovered; a second check valve (39) provided at the condensate water pipe (35) so as to prevent condensate water backflow; and a steam regeneration valve (41) provided at a steam recovery pipe (40), which is provided to communicate with the steam tank (38), so as to prevent the steam from being transferred to the steam recovery pipe (40) when the driving of the pump (33) stops, opened so as to allow the compressed steam to pass therethrough when the steam (22) is compressed by the condensate water (13) through the driving of the pump (33), and closing a flow path when the valve is raised by the condensate water.
