The utility model provides a vertical spinning membrane oxygen removal device for gray water. Its beneficial effect is that the mixing filter device is characterized by using the principle of the injector, and the water of different pressures is mixed through the mixing tube and then mixed into water with the same pressure to enter the filter chamber. Part of the particulate matter is filtered out before entering the water chamber to avoid bias flow and a large amount of gray water entering and blocking the spin membrane tube. This inlet method replaces the mixer set on the original system with a simple mixing tube and filtering device. Secondary deaeration is used as a deep deaeration. Pall rings with the same height and diameter are selected. There are rectangular holes on the side of the ring. The tongue leaves of the holes are bent to the center of the ring. - Liquid two-phase contact provides sufficient surface area for medium and heat exchange, and the Pall ring can be taken out through the discharge hole for cleaning and replacement. The reinforcement ring is provided in the deaeration water tank to increase the rigidity of the water tank, and at the same time reduce the thickness of the equipment and reduce the construction cost. The auxiliary steam heating pipe is installed in the deaerator water tank, which can not only realize the low-temperature quick start of the deaerator, but also increase the water temperature during the normal operation of the deaerator. The deoxygenated water tank is equipped with a water outlet device, which can prevent impurities from entering the feed water pump and prevent the formation of vortices at the water outlet.

detailed description

Referring to the accompanying drawings, the vertical spin film deaerator for gray water provided by the utility model will be described in detail in combination with an embodiment.

Example

With reference to Fig. 1, the gray water of the present embodiment uses the vertical spinning membrane deaeration device, and it comprises deaeration tower 17 and deaeration water tank 18, is connected by small hole pipeline between deaeration tower 17 and deaeration water tank 18, deaeration The upper part of the oxygen water tank 18 is provided with a steam conduit 14, and the steam conduit 14 is connected to the bottom of the deaeration tower 17 through a small hole pipeline. Oxygen component, high temperature water source inlet pipe 13, secondary deoxygenation component, described primary deoxygenation component comprises clapboard 10, double-flow communication pipe 8, spin film tube 7, mixing filter device 6 and secondary steam pipe 12, and divides There are water chamber, air chamber and water film skirt chamber, the partition plate 10 is fixed on the deaeration tower 17, the double-flow communication pipe 8 and the spiral membrane pipe 7 are arranged on the partition board 10, and the mixing and filtering device 6 is arranged on the deaeration tower 17 cylinder At the water inlet outside the body, the secondary steam pipe 12 and the mixing and filtering device 6 are relatively arranged on the deaeration tower 17 and the position of the secondary steam pipe 12 is lower than the mixing and filtering device 6. The secondary deaeration assembly includes a porous plate 4 And Pall ring packing 3, the porous plate 4 is fixed on the deaerator tower 17 by the fixed pressure piece 5, the Pall ring packing 3 is installed in the porous plate 4, and the secondary deaeration component is provided with a discharge hole 2.

The gray water for chemical industry can remove part of the particulate matter in the water through the water supply mixing and filtering device 6, and then enters the first-stage oxygen removal component. The inner hole is filled with rising heating steam, and the water absorbs a large amount of heating steam entering from the steam conduit 14 during the jet movement; in a very short time and a small stroke, a violent mixing and heating effect is generated, and the water temperature is greatly increased. The rotating water continues to spin down along the inner hole wall of the membrane tube to form a tumbling water film skirt. At this time, the heat and mass transfer effect of the water in the turbulent state is the best, most of the oxygen is removed, and the first oxygen removal is completed. process. The deoxygenated water after the primary deaeration is distributed through the secondary deaeration part, and then contacts with the Pall ring packing 3, and the water forms a water film on the surface of the packing layer, and the water is mixed with the water in the packing layer by the upwardly flowing steam. contact to complete the second oxygen removal process. The deoxygenated water enters the deoxygenated water tank 18 and enters the feed water pump through the water outlet device 16 . When the unit sheds the load, the cold water can be sent directly to the water outlet, which can effectively prevent the cavitation of the feed pump. When the water temperature is low, the auxiliary heating steam pipe 15 can be enabled to continue heating the water in the deaeration water tank 18, so as to utilize the further precipitation of free oxygen.
