Description

Technical Field

[0001] This utility model relates to the field of electric steam humidification steam distribution technology, specifically to the DV distribution pipe of an electric steam humidifier. Background Technology

[0002] In commercial settings such as laboratories, hospitals, military facilities, and high-end hotels, it is necessary to maintain the air in the factory or rooms within a certain humidity range, while also requiring high humidity precision to ensure the normal operation of experiments and production, as well as the needs of comfort and health. Therefore, electric steam humidification systems using electrodes or electric heating are required in central air conditioning systems to increase the humidity of the air. Electric steam humidifiers have the advantages of fast response, rapid steam production, and precise adjustment of steam production, thus meeting the requirements of high humidity control precision.

[0003] Existing steam nozzles are generally made of integrally welded metal, and the distribution holes of the steam nozzles are generally uniformly distributed. Due to the resistance encountered by unpressurized steam inside the pipe, the steam output is large at the near end and small at the far end. The part with large steam output cannot be absorbed in time and condenses, while the part with small steam output at the far end will result in insufficient air absorption and insufficient humidity. As the humidity gradually decreases, it will cause excessive condensation and uneven steam distribution. Therefore, we proposed the DV distribution pipe for electric steam humidifiers.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For examples, please refer to Figures 1-5 This utility model provides a technical solution:

[0025] The electric steam humidifier DV distribution pipe includes a PPS inlet 1, a steam distribution pipe 3, and an end plug 4. The steam distribution pipe 3 has equidistantly distributed steam nozzles, and the diameter and spacing of the steam nozzles are arranged in a regular pattern. One end of the steam distribution pipe 3 is fixedly connected to the PPS inlet 1. A drain outlet 2 is provided at the bottom of the PPS inlet 1. A flange 10 is threadedly connected to the side end of the PPS inlet 1. A second rubber ring 9 abuts between the PPS inlet 1 and the flange 10. The second rubber ring 9 seals the outer surface of the steam distribution pipe 3. The other end of the steam distribution pipe 3 is fixedly connected to an end plug 4 and a flow equalization plate 7.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a screw 6 is threadedly connected to the side end of the steam distribution pipe 3, and a lock nut 5 is threadedly connected to the outside of the screw 6. The side end of the screw 6 extends into the end seal 4 and the flow equalization plate 7. A first rubber ring 8 is provided between the end seal 4 and the flow equalization plate 7 and the steam distribution pipe 3. The first rubber ring 8 is tightly fitted with the steam distribution pipe 3. The first rubber ring 8 and the second rubber ring 9 are both circular in shape. Fins are fixedly connected to the surface of the flow equalization plate 7.

[0027] The aperture and arrangement of the steam distribution pipe 3 ensure uniform steam distribution, achieving high control precision and reducing condensation. The special engineering plastic PPS polyphenylene sulfide inlet is designed with a drain pipe interface. This material has good thermal insulation, high temperature resistance, corrosion resistance, stable mechanical properties, high electrical insulation, and flame retardancy, reducing condensate production and significantly saving energy. Furthermore, the nozzles and tilt angle of the distribution pipe can be rotated and adjusted under different duct pressures to ensure the steam output under different air conditioning pressures. At the same time, the fins balance and stabilize the steam flow, separate and collect condensate, and guide the flow, stabilizing the airflow and saving energy.

[0028] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the drain outlet 2 is circular in shape and is connected to the steam distribution pipe 3. The steam nozzles are arranged in a certain pattern. The number of nozzles and the nozzle spacing are different in each of the segments B1, B2, and B3. The PPS inlet 1 is circular in shape and is connected to the steam distribution pipe 3. The flange 10 is located outside the steam distribution pipe 3.

[0029] Among them, the steam distribution pipe 3 adapts to different humidification volumes, ensuring uniform steam distribution and condensate discharge according to fluid mechanics principles, thereby improving absorption efficiency and humidity control accuracy. Its targeted polyphenylene sulfide interface and stainless steel 304 distribution pipe meet the highest performance and hygiene requirements, making it hygienic, energy-efficient, highly practical, and long-lasting.

[0030] The working process of the present utility model: when the electric steam humidifier DV distribution pipe designed by the present solution is in operation, when there is a humidification demand, the non-pressure steam generated by the electric humidifier is conveyed through the pipeline to the air inlet, the PPS air inlet 1, of the steam distribution pipe 3 installed in the air conditioning humidification section, and enters the steam distribution pipe 3 through the air inlet. Since the steam is in a non-pressure state, it is necessary to ensure a proper inner diameter of the distribution pipe to ensure small steam pressure loss within an appropriate length and uniform pressure in all parts. Therefore, the distribution pipe needs to have different pipe diameters and distribution lengths. Meanwhile, in a specific distribution pipe, the spacing of the spray holes is distributed in sections B1, B2, B3 according to certain rules, the lengths of the spray pipes are different, the sections B1, B2, B3 are different, and the number of spray holes and the spacing of each section B1, B2, B3 are also different respectively, B1=L1×n1, B2=L2×n2; B3=L3×n3, which is characterized by L1<L2<L3. Different distribution rules are provided according to different models, so as to ensure that the steam distributed from each steam outlet hole is uniform and can be quickly absorbed by the air conditioning system, achieving high control accuracy and reducing condensation and energy waste. At the same time, the air inlet of the spray pipe is made of special engineering plastic PPS polyphenylene sulfide, and the air inlet is designed with a drain pipe interface, the drain pipe can discharge horizontally or vertically, ensuring that the condensed water can be discharged in time to avoid blocking the steam passage. Meanwhile, the PPS polyphenylene sulfide material has good thermal insulation effect, high temperature resistance (long-term use temperature up to 240℃), corrosion resistance, stable mechanical properties, high electrical insulation, flame retardancy and other characteristics, which reduces the generation of condensed water and has remarkable energy-saving effect; the steam distribution pipe 3 and the PPS air inlet 1 are connected by pressing the second rubber ring 9 through the flange 10, and the inclination angle between the spray holes of the distribution pipe can be rotated and adjusted under different air duct pressure occasions, so as to ensure the steam output under different air conditioning pressures. The uniform flow plate 7 on the right side of the tail end is designed with fins, which function to balance and stabilize the steam flow, separate and condense the condensed water, collect the condensed water and guide the flow, stabilize the air flow and save energy.

[0031] The standard parts used in the present application can be purchased from the market, the specific connection methods of each part adopt conventional means mature in the prior art such as bolts, rivets, welding, etc., the machinery, parts and equipment all adopt conventional models in the prior art, which are also general components and belong to the common general knowledge in the field.

[0032] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
