Description

Technical Field

[0001] The utility model belongs to the technical field of heating, and specifically relates to a water-sealed water dispenser. Background Art

[0002] Resource conservation and environmental protection are fundamental national policies of my country. Energy conservation and emission reduction are the inevitable choice for building a resource-conserving and environmentally friendly society. In recent years, with the increasing development and progress of society, the country's requirements for resource conservation, environmental protection, and the comprehensive utilization of energy have gradually increased.

[0003] In the heating industry, gas-fired boilers offer advantages over coal-fired boilers, such as lower pollution and higher thermal efficiency. Consequently, they have largely replaced coal-fired boilers as the primary heat source. During natural gas combustion in a boiler, approximately 92% of the energy is converted into heat, approximately 1% is lost as surface heat, and the remaining 7% is lost as exhaust heat. Therefore, exhaust heat recovery from flue gas is a top priority for clean, energy-efficient gas boiler retrofits. This flue gas heat recovery process produces a large amount of condensate, which is mixed with high-temperature flue gas. During the condensate recovery process, the high-temperature flue gas can easily enter the pipelines, causing them to melt. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the present invention provides a water-sealed water dispenser, comprising a water inlet pipe, a water tank, and a water outlet pipe. The water inlet pipe is located above the water tank, the water outlet pipe is located on the side wall of the water tank, and the side of the water tank facing the water inlet pipe is an open structure. The water tank contains room-temperature condensed water. The room-temperature condensed water acts as a water seal. The condensed water carrying high-temperature flue gas enters the water tank from the water inlet pipe. The room-temperature condensed water in the water tank can effectively isolate the flue gas. The flue gas with lower density is directly discharged into the atmosphere from the outlet of the water inlet pipe, thereby effectively avoiding direct contact between the high-temperature flue gas and the water pipe system, which may cause the pipe to melt and deform. This reduces the risk of corrosion of the pipe by acidic substances contained in the flue gas, extends the service life of the entire condensed water system, and reduces maintenance costs. In addition, this design also helps to maintain the water seal stability of the system, ensures that the condensed water can flow smoothly, and prevents the backflow of flue gas, thereby improving the safety and reliability of the system.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a water-sealed water dispenser, including a water inlet pipe, a water tank and a water outlet pipe, wherein the water inlet pipe is located above the water tank; the side of the water tank facing the water inlet pipe is an open structure, and the water tank is used to hold condensed water at room temperature; the water outlet pipe is arranged on the side wall of the water tank.

[0006] Optionally, the input end of the water inlet pipe is connected to the energy saver.

[0007] Optionally, the water inlet pipe extends to the inside of the water tank and is arranged above the liquid level of the normal temperature condensed water.

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0024] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Although the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation, the form, quantity, positional relationship and proportion of each component in actual implementation can be changed at will under the premise of realizing the technical solution of this party, and the component layout form may also be more complicated.

[0025] Example

[0026] This embodiment provides a water-sealed water dispenser, such as Figure 1 As shown, it includes a water inlet pipe 1, a water tank 2 and a water outlet pipe 3.

[0027] like Figure 1 As shown, the water inlet pipe 1 is located above the water tank 2. In this embodiment, the water-sealed water dispenser is used in a flue gas condensate water recovery system. Therefore, the input end of the water inlet pipe 1 is connected to the economizer 5 in the recovery system. The economizer 5 generates condensate during the flue gas waste heat recovery process, and the water inlet pipe 1 is used to receive the condensate generated by the economizer 5.

[0028] As an example, the water inlet pipe 1 is made of carbon steel material, which has high strength and hardness and is suitable for bearing greater pressure and load.

[0029] As an example, the size of the water inlet pipe 1 can be determined according to actual needs. In this embodiment, the size of the water inlet pipe 1 is DN100.

[0030] For example, the water inlet pipe 1 is provided with a joint flange 4 made of stainless steel. This design fully utilizes the corrosion and heat resistance of stainless steel. Stainless steel joint flanges can withstand various harsh environments, such as acidic and alkaline media and high temperatures, without rusting or damaging. This ensures the long-term stability and safety of the water outlet pipe, reducing maintenance costs and potential leakage risks.

[0031] like Figure 1As shown, the side of the water tank 2 facing the water inlet pipe 1 is an open structure. The water tank 2 contains room temperature condensate. The water inlet pipe 1 extends into the interior of the water tank 2 and is arranged above the liquid level of the room temperature condensate. As an example, the volume of the room temperature condensate accounts for one quarter to one third of the volume of the water tank 2. The room temperature condensate acts as a water seal. The condensate enters the water tank 2 from the water inlet pipe 1. The room temperature condensate in the water tank 2 can effectively isolate the flue gas. The low-density flue gas is discharged directly into the atmosphere after being discharged from the outlet of the water inlet pipe 1. This design effectively avoids direct contact between the high-temperature flue gas and the water pipe system, reducing the risk of corrosion of the pipeline by acidic substances that may be contained in the flue gas, thereby extending the service life of the entire condensate system and reducing maintenance costs. In addition, this design also helps to maintain the stability of the system's water seal, ensure that the condensate can flow smoothly, and prevent flue gas backflow, thereby improving the safety and reliability of the system.

[0032] As an example, the size and wall thickness of the water tank 2 can be selected according to actual conditions. In this embodiment, the length of the water tank 2 is between 30 cm and 50 cm, preferably 40 cm; the width of the water tank 2 is between 30 cm and 50 cm, preferably 40 cm; and the wall thickness of the water tank is between 0.12 cm and 0.18 cm, preferably 0.15 cm.

[0033] For example, water tank 2 is made of high-temperature and corrosion-resistant stainless steel. Commonly selected stainless steel grades include 304 or 316, which offer excellent resistance to oxidation, corrosion, acid and alkali, and high temperatures. For example, 304 stainless steel is widely used in applications such as electric furnace tubes, with a maximum operating temperature of approximately 427°C. 316 stainless steel, with the addition of molybdenum, has improved resistance to pitting and crevice corrosion, making it suitable for use in chloride-rich environments and capable of withstanding temperatures up to 871°C during intermittent operation. These properties enable stainless steel water tanks to withstand long-term use in a variety of environmental conditions, maintaining water quality and preventing damage caused by high temperatures or corrosive substances, thereby ensuring the tank's durability and reliability.

[0034] like Figure 1 As shown, the water outlet pipe 3 is provided on the side wall of the water tank 2 and is used to output the condensed water after the flue gas is removed. In this embodiment, the water-sealed water dispenser is used in the flue gas condensate water recovery system. Therefore, the output end of the water outlet pipe 3 is connected to the condensate main pipeline 6 in the recovery system, and the water outlet pipe 3 is used to output the condensed water after the flue gas is removed to the condensate main pipeline 6.

[0035] As an example, the water outlet pipe 3 is made of corrosion-resistant PE (Polyethylene) material. The water outlet pipe 3 made of corrosion-resistant PE material can effectively resist erosion by various chemical substances, extend its service life, ensure water quality safety, and has low maintenance costs.

[0036] As an example, the size of the water outlet pipe 3 can be determined according to actual needs. In this embodiment, the size of the water outlet pipe 3 is DN100.

[0037] For example, outlet pipe 3 is provided with a joint flange 4 made of stainless steel. This design fully utilizes the corrosion and heat resistance of stainless steel. Stainless steel joint flanges can withstand various harsh environments, such as acidic and alkaline media and high temperatures, without rusting or damaging. This ensures the long-term stability and safety of the outlet pipe, reducing maintenance costs and potential leakage risks.

[0038] The water-sealed water dispenser provided in this embodiment can effectively avoid direct contact between high-temperature flue gas and the water pipe system, reduce the risk of corrosion of the pipeline by acidic substances contained in the flue gas, extend the service life of the entire condensate water system, and reduce maintenance costs; in addition, the water-sealed water dispenser also helps to maintain the water seal stability of the system, ensure that the condensate can flow smoothly, and prevent flue gas backflow, thereby improving the safety and reliability of the system.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
