Description

Technical Field

[0001] The utility model relates to the technical field of deaerators, in particular to a rotatable and liftable deaerator. Background Art

[0002] Deaerators are key components of boilers and heating systems. Their primary function is to remove dissolved oxygen and other gases from the feedwater of thermal systems, preventing corrosion of thermal equipment and ensuring the safe operation of power plants and industrial boilers. Deaerators are primarily classified into two categories: rotary film deaerators and vacuum deaerators. Rotary film deaerators include new rotary film deaerators and high-pressure deaerators, while vacuum deaerators are categorized into low-pressure vacuum deaerators and two-stage jet vacuum deaerators. Deaerators are widely used to deoxygenate feedwater for various power station boilers, industrial boilers, and thermal power plant makeup water. Their efficient deoxygenation capacity and stable performance are crucial for ensuring the safe operation of thermal equipment.

[0014] 1. The fixed seat in the present invention can adjust the angle, and the setting of the spiral elevator can adjust different heights to adapt to different installation environments. By rotating and lifting, the deaerator can be easily moved to a position that is convenient for maintenance and overhaul, reducing the difficulty of maintenance and downtime, and improving the reliability and service life of the equipment.

At the same time, the inlet water temperature is steadily increased with the operating state of the deaerator body, thereby solving the problem of unstable inlet water temperature, thereby avoiding vibration of the rotary film deaerator due to temperature problems during operation, and preventing equipment damage. The thermal insulation layer arranged on the outside of the deaerator water tank reduces the loss of heat inside the deaerator water tank, thereby reducing heating costs. Thermal insulation is performed by the vacuum chamber. In a vacuum environment, since there is no fluid, heat convection is also completely eliminated, thereby reducing heat dissipation.

[0028] Working principle: When in use, water enters through the rotary membrane device water inlet pipe 17 and flows along the heat absorption tube 18. When the water flows, its own threaded setting increases the contact area with the deaeration water tank 13. The heat dissipated in the deaeration water tank 13 can heat the water in the heat absorption tube 18. The water absorbs the heat of the deaeration water tank 13, reducing the heating cost. At the same time, the inlet water temperature is steadily increased with the operating state of the deaerator body 1, thereby solving the problem of unstable inlet water temperature, thereby avoiding vibration of the rotary membrane deaerator due to temperature problems during operation, and preventing equipment damage. The heated water enters the rotary membrane device 3, and the water forms a water film skirt through the rotary membrane device 3 to exchange heat with the heating steam, forming a primary deoxygenation. Subsequently, the feed water comes into contact with the rising secondary heated steam through the water sprinkling grate 26. The feed water that has been roughly deoxygenated through the rotary film section is secondary distributed on the water sprinkling grate 5 and falls evenly on the packing layer 6 installed thereunder in the form of rain. The deoxygenated water is collected in the deoxygenated water tank 13. The insulation layer 14 arranged on the outside of the deoxygenated water tank 13 reduces the heat loss inside the deoxygenated water tank 13, thereby reducing the heating cost. The vacuum chamber 16 is used for thermal insulation. In a vacuum environment, since there is no fluid, heat convection is also completely eliminated, thereby reducing heat dissipation. The fixed seat 9 realizes angle adjustment, and the output end of the fixed seat motor 25 drives the fixed seat driving gear. 27 rotates, the fixed seat driving gear 27 drives the driven internal gear 28 to rotate, and the driven internal gear 28 drives the upper screw elevator 11 to rotate, thereby achieving angle adjustment. The setting of the screw elevator 11 can be adjusted to different heights. The motor of the screw elevator 11 drives the driving screw 21 to rotate. The driving screw 21 drives the screw sleeve 22 to rotate through the meshing connection. The internal thread of the screw sleeve 22 drives the screw 12 up and down, thereby achieving height adjustment to adapt to different installation environments. By rotating and lifting, the deaerator can be easily moved to a position convenient for maintenance and overhaul, reducing maintenance difficulty and downtime, and improving the reliability and service life of the equipment. By precisely controlling the position and angle of the deaerator, the utilization rate of the heating steam can be optimized, unnecessary energy consumption can be reduced, and energy efficiency can be improved. In an emergency, the deaerator can be quickly moved to a safe position by rotating and lifting to avoid damage to personnel and equipment.
