[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] In order to solve the technical problems in the background technology, a steam condensation recovery system for a hot water storage tank is provided as follows:

[0028] Combination Figure 1-Figure 6As shown, the utility model provides a steam condensation recovery system for a hot water storage tank, comprising a collecting mechanism 1 for collecting steam from a hot water storage tank 5, a recovery mechanism 2 for condensing steam is provided at the bottom of the collecting mechanism 1, a recovery member 3 connected to the collecting mechanism 1 is provided inside the recovery mechanism 2, and the recovery member 3 can assist the recovery mechanism 2 in condensing the incoming steam;

[0029] The recovery mechanism 2 includes a recovery box 21, a liquid inlet pipe 22 and a liquid guide pipe 23. A liquid inlet pipe 22 is provided on one side of the top of the recovery box 21, and a liquid guide pipe 23 is provided on one side of the bottom of the recovery box 21. The end of the liquid guide pipe 23 away from the recovery box 21 is connected to the hot water storage tank 5. A condensation chamber is formed inside the recovery box 21. The water of condensed steam will be injected into the condensation chamber by the liquid inlet pipe 22. The recovery component 3 is located inside the condensation chamber. The recovery component 3 includes an air collecting plate 31, an air inlet pipe 32 and an air distribution pipe 33. The air collecting plate 31 is arranged through the top of the recovery box 21. The air collecting plate 31 can gather the incoming steam and then introduce it into the air distribution pipe 33. An air inlet pipe 32 is provided at the bottom of the air collecting plate 31. An air distribution pipe 33 is provided at the bottom of the air inlet pipe 32. There are multiple groups of air distribution pipes 33 below the air inlet pipe 32. The multiple groups of air distribution pipes 33 are distributed in an array. The multiple groups of distributed air distribution pipes 33 can divert steam so that the water in the condensation chamber can evenly absorb heat and condense the steam.

[0030] In this embodiment, a liquid guide plate 24 is provided inside the condensation chamber. A plurality of liquid guide plates 24 are provided inside the condensation chamber. The plurality of liquid guide plates 24 are distributed at equal intervals. The plurality of liquid guide plates 24 are distributed in a staggered manner. An S-structured condensation channel is formed between the liquid guide plates 24. The condensation channel formed by the liquid guide plate 24 can increase the flow path of condensed water in the condensation chamber, so that the condensed water can fully cool and condense the steam in the gas distribution pipe 33, and at the same time can guide the steam to flow upward after entering the bottom of the condensation chamber to contact with the condensed water for condensation.

[0031] In this embodiment, a flow port is formed between the liquid guide plate 24 and the condensation chamber, and a gas distribution net 25 is arranged inside the flow port. The arrangement of the gas distribution net 25 can disperse the steam when the steam flows upward, so that the steam can fully contact with the condensed water.

[0032] In this embodiment, the gas distribution pipe 33 is connected to the liquid guide plate 24 through the bottom end of the gas distribution pipe 33 is located at the bottom of the condensation chamber, and the gas distribution pipe 33 that penetrates to the bottom of the condensation chamber can deliver the steam and the condensed water formed by the condensation of the steam to the bottom of the condensation chamber;

[0033] The S-shaped condensation channel formed inside the condensation chamber can cool down the steam inside the gas distribution pipe 33 while guiding the uncondensed steam to flow upward along the condensation channel to fully contact the condensed water, so that the steam can dissipate heat and condense more evenly and quickly during the condensation recovery process, which is beneficial to improving the steam recovery efficiency.

[0034] The implementation principle of the first embodiment is as follows: the steam generated by the hot water storage tank 5 and requiring to be recovered will enter the recovery component 3 inside the recovery mechanism 2 through the collection mechanism 1, and the recovery component 3 will transport the steam downward through the air distribution pipes 33 distributed in an array. During this process, the condensed water in the recovery tank 21 will contact the air distribution pipes 33, so as to achieve the purpose of preliminary condensation of the steam inside the air distribution pipes 33. Then, the uncondensed steam in the air distribution pipes 33 will enter the bottom of the condensation chamber, and then the steam will flow upward along the S-structured condensation channel formed by the liquid guide plate 24. The flowing steam will continuously contact and condense with the condensed water, and the water formed by the condensation of the steam will mix with the condensed water in the condensation chamber. In this way, the condensed water after heat recovery can be replenished to the inside of the hot water storage tank 5 when needed, thereby reducing the energy consumption of the hot water storage tank 5. Example

[0035] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0036] In order to enable the recovery mechanism 2 to achieve the purpose of efficiently condensing steam, this embodiment provides the following design:

[0037] The collecting mechanism 1 comprises a collecting box 11, a collecting pipe 12 and a recovery pipe 13. The collecting box 11 is located above the recovery box 21. The recovery pipe 13 is provided at the bottom of the collecting box 11. The recovery pipe 13 is communicated with the recovery box 21. A control valve 15 is provided on the outside of the recovery pipe 13. The collecting box 11 is provided with a collecting pipe 12 at the top. A one-way valve 14 is provided on the outside of the collecting pipe 12. One end of the collecting pipe 12 away from the collecting box 11 is communicated with the hot water storage tank 5. The collecting box 11 can compress and collect the steam so as to block the steam when the recovery mechanism 2 introduces the condensed water into the hot water storage tank 5 to prevent the steam from entering the hot water storage tank 5 again.

[0038] In this embodiment, a flow guiding mechanism 4 is provided outside the recovery mechanism 2, and the flow guiding mechanism 4 includes a liquid pump 41 and a flow guiding pipe 42. The liquid pump 41 is fixedly provided at the bottom of the recovery mechanism 2, and the water inlet end of the recovery mechanism 2 is communicated with the bottom of the condensation chamber. The flow guiding pipe 42 is provided at the top of the liquid pump 41. The flow guiding pipe 42 is provided with multiple groups. The liquid pump 41 provided in the flow guiding mechanism 4 can control the relative flow of condensed water and steam inside the condensation chamber through the flow guiding pipe 42, thereby improving the contact uniformity between the condensed water and the steam.

[0039] The implementation principle of the second embodiment is as follows: when the condensed water in the recovery mechanism 2 needs to be replaced or the condensed water is introduced into the hot water storage tank 5, the control valve 15 in the collection mechanism 1 blocks the steam, and the steam can be temporarily stored in the collection tank 11. When the steam can be recovered later, the steam is sent to the recovery mechanism 2;

[0040] During the steam recovery process, the liquid pump 41 in the guide mechanism 4 cooperates with the guide pipe 42 to deliver the condensed water at the bottom of the condensation chamber to the top of the condensation chamber. In this way, the condensed water can flow relative to the steam inside the condensation chamber, allowing the condensed water and steam to contact and condense more evenly and fully.
