Closed type condensate water recovery device

Abstract

The invention discloses a device which consists of an enclosed cylindrical condensed water recovery water tank which is provided with a filter, a guide plate, a circular steam separator, a deflector and a cavitation eliminator; a wash water valve, a thermometer, a pressure gauge, a pressure balancer, a water level gauge, a high pressure pump, a booster, a PLC control box, etc. The input high-temperature saturated condensed water is separated into high-temperature condensed water by the guide plate and the circular steam separator; the cavitation to the water pump after being output is eliminated by pressurizing the cavitation eliminator; finally, the recovered high-temperature condensed water is delivered to the devices or units needing the recovered condensed water by pressurizing the high pressure pump and the pressure balancer. The device adopts the PLC control box for automatically controlling operation, and has the advantages of advanced technology, novel structure and being capable of effectively recovering and using the high-temperature saturated condensed water; besides, the device has obvious economic and social benefits, and can be widely popularized and applied.

Description

Technical field [0001] The invention relates to an environment-friendly and energy-saving mechanical product, in particular to a closed condensed water recovery device. Background technique [0002] At present, many industrial and mining enterprises use steam as a heat source to complete various heating processes. Steam releases latent heat of vaporization in steam-using equipment and becomes saturated condensed water at the same temperature and pressure. The temperature exceeds 100 ° C. The existing open recovery method When the water temperature drops to a temperature of about 75°C, which does not cause cavitation in ordinary water pumps, it will be flashed twice under atmospheric pressure, resulting in a large amount of latent heat loss, and the energy utilization rate is less than 60%. The water quality conditions after the original softening treatment have greatly increased the cost of recycling. Contents of the invention [0003] The object of the present invention ...
