Description

Technical Field

[0001] The present invention relates to the field of steam humidification systems, and specifically to a double-hydrophobic steam humidification system. Background Art

[0002] For rooms with winter heating, during winter heating operation, it often causes relatively low air relative humidity and dry air in the heating rooms. Experts introduce that when the air humidity is below 40%RH, the nasal and pulmonary respiratory mucosa dehydrates, the elasticity decreases, dust, bacteria, etc. are easily attached to the mucosa, stimulating the throat to cause coughing, and at the same time, it is easy to develop respiratory diseases such as bronchitis and asthma. In addition, the reproduction speed of influenza viruses will accelerate in a dry environment. After the air conditioner is turned on for a period of time, the indoor air will be relatively dry with too low humidity. Therefore, it is particularly important to humidify the indoor air so that the air humidity in the air-conditioned room is within the range suitable for the human body.

[0003] Steam humidification is a commonly used humidification method for air humidification. Steam humidification uses an external steam source, and through a steam-water separation device, dry steam is ensured. The spray pipe is preheated by a double-layer heat-insulating jacket to prevent the condensed water in the spray pipe from spraying into the air-conditioning system. The condensed water generated in the spray pipe flows back to the flash chamber and is re-evaporated to become steam for humidification again. Steam humidification is isothermal humidification, with high humidification efficiency and fast humidification control response speed, and is more suitable for occasions with a relatively large demand for humidification. For air conditioners with a steam source supply, steam humidification is an ideal humidification method.

[0004] Currently, the spray pipes of steam humidifiers on the market generally adopt a double-layer jacket design, which has a large processing difficulty, is bulky and not easy to be arranged in the narrow space of the air conditioner, and is prone to dirt accumulation and bacteria breeding in the middle. Although the steam boiler station is equipped with a water separation device, the heat insulation of the steam transmission pipeline along the way cannot be completely adiabatic. When the steam is transported along the pipeline, some condensed water will inevitably be generated, which will cause the condensed water to enter the steam humidifier. Moreover, for the steam humidifier with a double-layer jacket design, the jacket needs to be preheated for a period of time each time the humidification work is started to raise the temperature of the jacket. During this period, a certain amount of water mist will inevitably be sprayed out from the spray pipe, causing the air duct and the components in the air duct to be affected by moisture, corroded and bacteria to breed. Especially, the working reliability of electrical components will be greatly reduced after being affected by moisture. Summary of the Invention

[0005] The present invention provides a double-hydrophobic steam humidification system to solve the problem of water spraying during the operation of existing steam humidifiers.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A double-hydrophobic steam humidification system includes a steam humidifier (6), and also includes a stop valve (1), a solenoid valve (3), a drain valve A (4), and a drain valve B (5). The inlet end of the stop valve (1) is connected to a steam source, the outlet end of the stop valve (1) is connected to the inlet end of the solenoid valve (3), the outlet end of the solenoid valve (3) is respectively connected to the steam inlet end of the steam humidifier (6) and the inlet end of the drain valve A (4), the condensate outlet end of the steam humidifier (6) is connected to the inlet end of the drain valve B (5), and the outlet ends of the drain valve A (4) and the drain valve B (5) are connected to a condensate drain port.

[0007] Furthermore, it also includes a steam filter (2), and the steam filter (2) is connected in communication between the outlet end of the stop valve (1) and the inlet end of the solenoid valve (3).

[0008] Furthermore, the steam humidifier (6) is provided with a drainage chamber (7). The steam inlet end and the condensate outlet end of the steam humidifier (6) are respectively arranged in the drainage chamber (7). The drainage chamber (7) is also provided with a steam outlet end, and there are fillers in the drainage chamber (7); 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 drain 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).

[0009] Furthermore, a throttle plate (7-1) is arranged inside the steam inlet end of the drainage chamber (7).

[0010] Compared with the prior art, the advantages of the present invention are as follows: 1. As a new type of steam humidification, the present invention respectively sets a drain valve at the front end of the traditional steam humidifier and in the drainage chamber of the steam humidifier. The drain valve A set at the front end of the humidifier can exclude the condensate in the incoming steam, reducing the probability of condensate entering the steam humidifier. The drain valve B set below the drainage chamber of the steam humidifier can timely discharge the condensate generated when the steam passes through the drainage chamber of the humidifier. Through these two drain valves, the condensate condensed due to various reasons before the steam enters the spray bar of the humidifier can be effectively excluded, ensuring that no steam condensate is ejected from the steam humidifier, greatly reducing the probability of condensate in the steam source entering the steam humidifier, effectively avoiding the water spraying phenomenon of the steam humidifier, and preventing the air-conditioning pipeline and other components from being corroded due to moisture.

[0011] 2. The solenoid valve set in the present invention can realize the automatic control of humidification, effectively control the humidification amount of humidification, with simple control and high reliability.

[0012] 3. Each component of the steam humidification system of the present invention is connected through pipelines, which is easy to arrange in the narrow space of the air conditioner, reduces the difficulty of designing the humidification system for the air conditioner unit, humidifies while heating, and realizes dual use of one machine.

[0013] 4. The present invention is easy to implement and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the drawings and embodiments.

[0018] As Figure 1 、 Figure 2 shown, this embodiment discloses a double-trap steam humidification system, including a globe valve 1, a steam filter 2, a solenoid valve 3, a steam humidifier 6, a trap A 4, and a trap B 5. The steam humidifier 6 is provided with a drainage chamber 7. The steam inlet end O and the condensate outlet end P of the steam humidifier 6 are respectively arranged in the drainage chamber 7. A throttling plate 7-1 is arranged in the steam inlet end O. The drainage chamber 7 is connected to the spray rod in the steam humidifier 6 through the steam outlet end Q. There is a filler 7-2 in the drainage chamber 7.

[0019] The inlet end of the globe valve 1 is connected to an external steam source. The outlet end of the globe 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 respectively connected to the steam inlet end O of the drainage chamber 7 in the steam humidifier and the inlet end of the trap A 4. The condensate outlet end P of the drainage chamber 7 in the steam humidifier is connected to the outlet end of the trap B 5. The outlet ends of the trap A 4 and the trap B 5 are connected and then connected to the condensate drain outlet.

[0020] The above-mentioned components of the steam humidification system are connected together through steam pipelines (steam pipelines generally use copper pipes or stainless steel seamless steel pipes). The connection type is determined according to the interface styles of the components. The standard interfaces of these components are generally threaded or flange interface methods. Corresponding threads or mating flanges can be configured on the pipelines to achieve connection. The sealing gaskets for connection should be made of materials resistant to high steam temperature. Graphite metal wound gaskets, copper gaskets, etc. can be used for flange gaskets.

[0021] The steam humidification system of this embodiment realizes humidification by using an external steam source, and is particularly suitable for air conditioning units using steam heating, without the need to separately provide a steam source for air conditioning steam humidification. The steam source of the steam humidification system of this embodiment first enters the stop valve 1, and the stop valve 1 is responsible for cutting off the steam when the steam source is not required, facilitating the maintenance and replacement of other components in the steam humidification system; after the steam passes through the stop valve 1, it enters the steam filter 2, which can filter out impurities such as debris, scale, and oxide scale that may be contained in the steam, reducing the reliability of the operation of the solenoid valve 3, steam humidifier 6, and steam trap at the rear end; after the steam passes through the steam filter 2, it enters the solenoid valve 3, and the solenoid valve 3 performs opening and closing actions according to the electrical control signal to control the humidification amount, enabling the steam humidification system to automatically control the humidification amount; after the steam passes through the solenoid valve 3, it is divided into two paths, one path enters the condensate chamber 7 of the steam humidifier 6, and the other path enters the steam trap A 4. When arranging the steam humidification system, the pipeline leading to the steam trap A 4 should be lower than the pipeline of the condensate chamber 7 of the steam humidifier 6, so that the condensate contained in the steam entering the condensate chamber 7 of the steam humidifier 6 is discharged out of the entire system through the steam trap A 4.

[0022] The steam entering the steam humidifier 6 first enters the condensate chamber 7 of the steam humidifier 6, and there is a filler 7-2 in the condensate chamber 7. The size of the throttle plate 7-1 can be selected according to the humidification amount of the steam humidifier, throttling to control the amount of steam entering the steam humidifier 6. After passing through the throttle plate 7-1, it then passes through the filler 7-2 and enters the spray bar of the steam humidifier 6. The filler 7-2 filters the condensate generated when passing through the throttle plate 7-1, causing the condensate to flow to the bottom of the condensate chamber 7 and be discharged through the condensate outlet end P at the bottom through the steam trap B 5.

[0023] The tail of the spray bar in the steam humidifier 6 should be appropriately tilted upwards during construction and installation (the tilt angle is preferably 5-8 degrees), so that a small amount of condensate entering the spray bar can flow back to the condensate chamber 7 and be discharged through the steam trap B 5.
