Description

Technical Field

[0001] This utility model relates to the field of steam humidification systems, specifically a double hydrophobic steam humidification system. Background Technology

[0002] In rooms heated during winter, the relative humidity is often low, resulting in dry air. Experts explain that when the humidity drops below 40% RH, the mucous membranes of the nose and lungs dehydrate, reducing their elasticity. Dust and bacteria easily adhere to these membranes, irritating the throat and triggering coughs. This also increases the risk of respiratory illnesses such as bronchitis and asthma. Furthermore, influenza viruses multiply faster in dry environments. Since air conditioning becomes quite dry after a period of time, humidifying the indoor air to maintain a comfortable humidity level is crucial.

[0003] Steam humidification is a common method of air humidification. It uses an external steam source and a steam-water separation device to ensure dry steam is obtained. The nozzle is preheated with a double-insulated jacket to prevent condensate from spraying into the air conditioning system. The condensate generated in the nozzle flows back to the flash chamber and undergoes secondary evaporation to become humidifying steam again. Steam humidification is isothermal humidification, with high efficiency and fast humidification control response, making it more suitable for applications with large humidification requirements. For air conditioning systems with a steam source, steam humidification is an ideal humidification method.

[0004] Currently, most steam humidifier nozzles on the market use a double-jacket design, which is difficult to manufacture, bulky, and difficult to install in the confined space of an air-conditioned room. Furthermore, the nozzles are prone to trapping dirt and bacteria. Although steam boiler stations are equipped with water separation devices, the insulation of the steam delivery pipelines along the route cannot be completely insulated. As steam travels along the pipelines, some condensation inevitably occurs, which can then enter the steam humidifier. Moreover, steam humidifiers with a double-jacket design require a preheating period before each humidification cycle, during which time some water mist inevitably sprays out from the nozzles. This moisture can cause corrosion and bacterial growth in the air ducts and components, especially significantly reducing the reliability of electrical components. Utility Model Content

[0005] This invention provides a dual hydrophobic steam humidification system to solve the problem of water spraying that occurs when existing steam humidifiers are in operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A dual hydrophobic steam humidification system includes a steam humidifier (6), a shut-off valve (1), a solenoid valve (3), a steam trap A (4), and a steam trap B (5). The inlet end of the shut-off valve (1) is connected to a steam source, and the outlet end of the shut-off valve (1) is connected to the inlet end of the solenoid valve (3). The outlet end of the solenoid valve (3) is connected to the steam inlet end of the steam humidifier (6) and the inlet end of the steam trap A (4), respectively. The condensate outlet end of the steam humidifier (6) is connected to the inlet end of the steam trap B (5), and the outlet ends of the steam trap A (4) and the steam trap B (5) are connected to the condensate drain outlet.

[0008] Furthermore, it also includes a steam filter (2), which is connected between the outlet end of the shut-off valve (1) and the inlet end of the solenoid valve (3).

[0009] Furthermore, the steam humidifier (6) has a drainage chamber (7), the steam inlet end and the condensate outlet end of the steam humidifier (6) are respectively located in the drainage chamber (7), the drainage chamber (7) is also provided with a steam outlet end, and the drainage chamber (7) is filled with a filling material; the outlet end of the solenoid valve (3) is connected to the steam inlet end of the drainage chamber (7) in the steam humidifier (6), the inlet end of the drainage valve B (5) is connected to the condensate outlet end of the drainage chamber (7) in the steam humidifier (6), and the steam outlet end of the drainage chamber (7) is connected to the spray bar in the steam humidifier (6).

[0010] Furthermore, a throttling plate (7-1) is provided inside the steam inlet end of the condensate chamber (7).

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. This utility model, as a novel type of steam humidification, sets a condensate drain valve at the front end of a traditional steam humidifier and at the condensate drain chamber. The condensate drain valve A at the front end of the humidifier can drain condensate from the incoming steam, reducing the probability of condensate entering the steam humidifier. The condensate drain valve B at the bottom of the condensate drain chamber can promptly drain condensate generated when the steam passes through the condensate drain chamber. By setting these two condensate drain valves, condensate generated due to various reasons before the steam enters the humidifier spray bar can be effectively drained, ensuring that no condensate is sprayed out of the steam humidifier. This greatly reduces the probability of condensate from the steam source entering the steam humidifier, effectively avoiding water spraying from the steam humidifier and preventing corrosion of air conditioning pipes and other components due to moisture.

[0013] 2. The solenoid valve in this utility model can realize automatic control of humidification, effectively control the humidification amount, and is simple to control with high reliability.

[0014] 3. The various components of this utility model steam humidification system are connected by pipes, making it easy to arrange in the small space of an air-conditioned room, reducing the difficulty of designing a humidification system for an air-conditioned unit, and humidifying while heating, achieving dual-purpose functionality.

[0015] 4. This utility model is easy to implement and has low cost. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 , Figure 2 As shown, this embodiment discloses a dual hydrophobic steam humidification system, including a shut-off valve 1, a steam filter 2, a solenoid valve 3, a steam humidifier 6, a steam trap A4, and a steam trap B5. The steam humidifier 6 has a condensate drain chamber 7. The steam inlet end O and the condensate outlet end P of the steam humidifier 6 are respectively located in the condensate drain chamber 7. A throttling plate 7-1 is provided in the steam inlet end O. The condensate drain chamber 7 is connected to the spray bar in the steam humidifier 6 through the steam outlet end Q. The condensate drain chamber 7 contains a filler material 7-2.

[0021] The inlet end of the shut-off valve 1 is connected to an external steam source. The outlet end of the shut-off valve 1 is connected to the inlet end of the steam filter 2. The outlet end of the steam filter 2 is connected to the inlet end of the solenoid valve 3. The outlet end of the solenoid valve 3 is connected to the steam inlet end O of the steam evacuation chamber 7 in the steam humidifier and the inlet end of the steam trap A4. The condensate outlet end P of the evacuation chamber 7 in the steam humidifier is connected to the outlet end of the steam trap B5. The outlet ends of the steam trap A4 and the steam trap B5 are connected to the condensate drain outlet.

[0022] The components of the steam humidification system are connected together by steam pipes (which are generally made of copper or stainless steel seamless pipes). The connection type is determined by the interface style of the components. The standard interfaces of these components are generally threaded or flanged. The connection can be achieved by fitting the corresponding threads or mating flanges on the pipes. The sealing gaskets used for the connection should be made of high-temperature resistant steam materials. The flange gaskets can be made of graphite metal spiral wound gaskets, copper gaskets, etc.

[0023] The steam humidification system in this embodiment utilizes an external steam source for humidification, making it particularly suitable for air conditioning units that use steam heating, eliminating the need for a separate steam source for air conditioning steam humidification. In this embodiment, the steam source of the steam humidification system first enters the shut-off valve 1. The shut-off valve 1 is responsible for cutting off the steam when the steam source is not needed, facilitating the maintenance and replacement of other components in the steam humidification system. After passing through the shut-off valve 1, the steam enters the steam filter 2, which can filter out impurities such as debris, oxide scale, and water scale that may be contained in the steam, reducing the reliability of the downstream solenoid valve 3, steam humidifier 6, and steam trap. After passing through the steam filter 2, the steam enters the solenoid valve 3. The solenoid valve 3 switches on and off according to the electrical control signal to control the humidification amount, enabling the steam humidification system to automatically control the humidification amount. After passing through the solenoid valve 3, the steam is divided into two paths: one path enters the steam trap chamber 7 of the steam humidifier 6, and the other path enters the steam trap A4. When arranging the steam humidification system, the pipe leading to the steam trap A4 should be lower than the pipe leading to the steam trap chamber 7 of the steam humidifier 6, so that the condensate contained in the steam entering the steam trap chamber 7 of the steam humidifier 6 can be discharged outside the entire system through the steam trap A4.

[0024] Steam entering the steam humidifier 6 first enters the evaporation chamber 7, which contains packing material 7-2. The size of the throttling plate 7-1 can be selected according to the humidification capacity of the steam humidifier, throttling to control the amount of steam entering the steam humidifier 6. After passing through the throttling plate 7-1 and then through the packing material 7-2, the steam enters the spray bar of the steam humidifier 6. The packing material 7-2 filters the condensate generated when passing through the throttling plate 7-1, causing the condensate to flow to the bottom of the evaporation chamber 7 and be discharged through the condensate outlet P at the bottom via the steam trap B5.

[0025] During construction and installation, the tail of the spray bar in the steam humidifier 6 should be tilted up appropriately (the tilt angle should be 5 to 8 degrees) so that a small amount of condensate entering the spray bar can flow back to the drainage chamber 7 and be discharged through the drain valve B5.
