Description

Technical Field

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

[0002] A deaerator is a device specifically designed to remove dissolved oxygen from water. Its operating principle is primarily based on Henry's law. Through specific structural design and operational procedures, such as spraying water into fine droplets that come into contact with air, heating to increase the dissolution rate, and cooling to promote gas separation, it effectively releases and discharges the oxygen dissolved in the water, ensuring that the water quality meets the required standards. The deaerator's connecting pipes refer to a series of pipes that connect the deaerator to other equipment or systems. Together, they form a piping system that transports fluids (such as water and steam) to achieve functions such as deoxygenation, heating, and water replenishment. These pipes include but are not limited to condensate pipes, drain pipes, desalinated water pipes, heating steam pipes, and recirculation pipes.

[0003] For example, the Chinese authorized patent "A Connecting Pipeline for a Thermal Deaerator" with publication number CN208579316U includes a first deaerator and a second deaerator. The first deaerator is provided with a first water outlet at the top and a second water outlet at the bottom; the second deaerator is provided with a third water outlet at the top and a fourth water outlet at the bottom. A first tee is fixedly connected to the first water outlet, a second tee is fixedly connected to the second water outlet, a third tee is fixedly connected to the third water outlet, and a fourth tee is fixedly connected to the fourth water outlet. An upper connecting pipe is connected between the first and third tees, and a lower connecting pipe is connected between the second and fourth tees. Connecting pipe interfaces can be added through the first, second, third, or fourth tees.

[0004] In actual use of the above-mentioned existing technology, high-temperature steam enters the deaerator through a delivery pipe. Since the steam delivery pipe is mostly made of metal and has high thermal conductivity, the heat of the steam is easily lost through the pipe body, which not only causes energy waste but also affects the heating effect of the water inside the deaerator. Therefore, it does not meet the existing needs. In this regard, we propose a connecting pipe for the deaerator. Utility Model Content

[0005] The purpose of the utility model is to provide a connecting pipe of a deaerator to solve the problem in the above background technology that the steam transmission pipe of the deaerator is prone to heat loss, resulting in energy waste and affecting the water heating effect.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a connecting pipe of a deaerator, comprising a deaerator cylinder; a water tank is provided below the deaerator cylinder, and the inner cavity of the deaerator cylinder is connected to the water tank, one end of the water tank is provided with a return water inlet pipe extending from the top, a first steam inlet pipe is provided below one side of the deaerator cylinder, a second steam inlet pipe is provided above the first steam inlet pipe, auxiliary heating chambers are provided in the inner walls of the first steam inlet pipe and the second steam inlet pipe, the auxiliary heating chambers of the first steam inlet pipe and the second steam inlet pipe are connected by a first connecting pipe, and the other end of the auxiliary heating chamber in the first steam inlet pipe is connected to the return water inlet pipe, the other end of the auxiliary heating chamber in the second steam inlet pipe is provided with a second connecting pipe, a filtering mechanism is installed at one end of the second connecting pipe, the water outlet pipe of the filtering mechanism is installed with a return water outlet pipe, and a circulating pump is installed on the outside of the return water outlet pipe.

[0007] Preferably, the upper end of the deaerator cylinder forms a water-forming chamber through a sealing partition, and the upper end of the other side of the deaerator cylinder is provided with a water inlet pipe, and the water inlet pipe and the return water outlet pipe are both connected to the water-forming chamber.

[0008] Preferably, a steam chamber is provided below the water assembly chamber, and the steam chamber is formed by a combination of a sealing partition and the inner wall of the deaerator cylinder, and the steam outlet of the second steam inlet pipe is connected to the steam chamber, and a steam-liquid network is installed below the inside of the deaerator cylinder, and the steam outlet of the first steam inlet pipe is located below the steam-liquid network.

[0009] Preferably, a plurality of film lifters distributed in a ring array are provided between the water assembly chamber and the steam chamber, and both ends of the film lifters are open structures and pass through the water assembly chamber and the steam chamber.

[0010] Preferably, a filter cartridge is installed inside the filter mechanism, and the filter cartridge is snap-fitted to the inner cavity of the filter mechanism, and the upper end of the filter cartridge is in an inclined structure.

[0011] Preferably, a heat insulation layer is provided on the outside of the auxiliary heat cavity, and the heat insulation layer consists of a heat insulation inner layer and a heat insulation outer layer.

[0012] Preferably, an exhaust pipe is provided at the top of the deaerator cylinder, and deoxygenated water discharge pipes are provided at the lower ends of both sides of the water tank.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a deoxygenated water circulation treatment component. The deoxygenated water falls from the deaerator into the water tank for storage and maintains a relatively high heat. By turning on the circulation pump, the deoxygenated water inside the water tank is transported to the auxiliary heating chamber in the first steam inlet pipe through the return water inlet pipe, and then enters the auxiliary heating chamber of the second steam inlet pipe through the first connecting pipe, and finally flows back to the water group chamber in the deaerator through the second connecting pipe and the return water outlet pipe. On the one hand, a part of the treated water is circulated into the deaerator again to improve the deoxygenation quality of the water. On the other hand, the high-temperature water body can release heat in the auxiliary heating chamber, which can not only preheat the steam inlet pipe, but also effectively reduce the heat loss of high-temperature steam during the transportation process, thereby reducing energy consumption and providing the premise for efficient deoxygenation of water bodies.

[0015] 2. The utility model provides an insulation layer on the inner wall of the first steam inlet pipe and the second steam inlet pipe. The insulation layer is composed of ceramic fiber blanket and glass fiber insulation felt. The double insulation layer design effectively reduces heat loss during steam transportation and improves energy utilization efficiency. The inner insulation material directly blocks the heat transfer of high-temperature steam, while the outer insulation material and air gap layer further block the diffusion of heat to the external environment. By reducing heat loss, the double insulation layer design enables the high-temperature water in the auxiliary heating chamber to release heat more effectively, preheating the steam inlet pipe, thereby improving the heating effect of the water inside the deaerator and further improving the deoxygenation efficiency. Due to the reduced heat loss, the heating energy required by the system is correspondingly reduced, thereby reducing energy consumption and operating costs.

[0016] 3. The utility model sets a filtering mechanism between the second connecting pipe and the return water outlet pipe. The inlet of the upper end of the filter cartridge inside the filter is designed to be inclined. The water flowing out of the second connecting pipe can completely enter the filter cartridge, intercepting impurities inside the water, and clean water enters the return water outlet pipe from the outside of the filter. This not only improves the purity of the water body and ensures the high standard of water quality inside the deaerator, but also avoids the potential damage of impurities to the auxiliary heating chamber and the deaerator cartridge, further enhances the stability and deoxygenation efficiency of the system, and extends the service life of the equipment.

[0025] The deaerator connecting pipeline integrates deoxygenated water circulation treatment components to achieve the recycling of deoxygenated water, which not only improves the deoxygenation quality of the water, but also uses the heat released by the high-temperature water in the auxiliary heating chamber to preheat the steam inlet pipe, effectively reducing the heat loss during the high-temperature steam transportation process, saving energy and creating favorable conditions for efficient deoxygenation.

[0027] See also Figure 2 and Figure 4 A filter cartridge 20 is installed inside the filter mechanism 10, and the filter cartridge 20 is snap-fitted to the inner cavity of the filter mechanism 10.

[0029] Working principle: When in use, the deoxygenated water falls from the deoxygenation cylinder 1 into the water tank 2 for storage, and maintains a relatively high heat itself.
