Description

Technical Field

[0001] This utility model relates to the field of steam-water separation technology, specifically to an energy-saving waste heat recovery device for steam condensation. Background Technology

[0002] A steam-liquid separator is a device used to remove water suspended in steam that cannot be drained through a steam trap. Depending on the structure, it can generally be divided into baffle separators, centrifugal separators, and adsorption separators. The working principle of a centrifugal gas-liquid separator is as follows: a large amount of water-containing steam or compressed air enters the steam-liquid separator and moves downwards in a centrifugal manner; the entrained water is separated out due to the decrease in speed.

[0003] Existing methods for separating steam and water, such as centrifugal separation, cannot achieve sufficient separation, and adsorption separators have low separation efficiency, failing to meet current requirements. Therefore, we propose an energy-saving waste heat recovery device for steam condensation. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving waste heat recovery device for steam condensation, in order to solve the problems mentioned in the background art, such as the inability of centrifugal separation to fully separate steam and water, and the low separation efficiency of adsorption separators, which cannot achieve efficient steam-water separation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving waste heat recovery device for steam condensation, comprising a condenser tank, an input pipe fixedly installed on one side of the condenser tank, an output pipe fixedly installed on the other side of the condenser tank, an insulation pipe provided on the outer side of the output pipe, a separating conveyor seat fixedly installed on the inner side of the upper end of the condenser tank, a spiral pressure frame rotatably connected between the separating conveyor seat and the condenser tank, a transmission vent seat installed at the bottom end of the spiral pressure frame, a transmission shaft installed in the middle of the transmission vent seat, a separating cover fixedly installed on the lower end face of the transmission vent seat, and a squeezing scraper installed at the bottom end of the separating cover;

[0006] A protective assembly is installed on the inner side of the middle part of the condenser. The protective assembly includes a support vent plate, an installation ring is installed on the side of the upper end face of the support vent plate, a locking ring is installed on the upper end of the installation ring, and an adsorption layer is installed on the inner side of the installation ring.

[0007] Preferably, a liquid distribution plate is fixedly installed in the middle of the lower end face of the supporting vent plate, and the lower end face of the liquid distribution plate is provided with multiple liquid collecting columns. The bottom end of the condenser is fixedly provided with a drain end, and the drain end is connected to the condenser through.

[0008] Preferably, a sealing cover is fixedly installed at the upper end of the condenser, and a drive motor is fixedly installed in the middle of the sealing cover.

[0009] Preferably, the condenser is connected to both the inlet pipe and the outlet pipe, the bottom end of the drive shaft passes through the separator conveyor seat and is fixedly connected to the drive vent seat, and the upper end of the drive shaft passes through the sealing cover and is connected to the drive motor via a coupling.

[0010] Preferably, the bottom end of the drive shaft is fixedly connected to the spiral pressure frame via a drive vent seat, the drive vent seat is rotatably connected to the bottom end of the separating conveyor seat, and the drive vent seat is connected to the adsorption layer via a separating cover.

[0011] Preferably, the upper and lower ends of the mounting ring are threadedly connected to the locking ring and the supporting ventilated plate, and the adsorption layer is disposed between the locking ring and the supporting ventilated plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a drive shaft and a drive vent seat to synchronously drive the spiral pressure frame and the separator to rotate. The spiral pressure frame can pressurize water vapor and achieve initial condensation of water vapor. An adsorption layer is provided between the locking ring and the support vent plate, so that the water vapor can be adsorbed twice by the adsorption layer under the guidance of the separator conveyor seat, so as to achieve full condensation of water vapor. Dry hot gas can be discharged through the separator conveyor seat and the output pipe, and condensate can be discharged through the drain end.

[0014] 2. This utility model features multiple adsorption columns on the lower end face of the separating plate, enabling further condensation and liquefaction of water vapor through the separating plate and the multiple adsorption columns, thereby improving the condensation effect. When the separator rotates, it simultaneously drives the squeezing scraper to rotate relative to the adsorption layer, thus squeezing the water in the adsorption layer during rotation, which helps maintain the high efficiency of the adsorption layer for water vapor adsorption. By combining centrifugation and adsorption to separate the steam and water, the steam and water can be fully separated with high separation efficiency, small temperature change of steam and water, and the recovery of residual heat and energy saving effect can be achieved.
