Description

Technical Field

[0001] This invention relates to the field of thermal storage equipment technology, and in particular to a heat-insulating breathing valve. Background Technology

[0002] Hot water storage technology is widely used in daily life, industrial production, and new energy fields. Its core objectives are to reduce heat loss, improve storage efficiency, and ensure safe use. Because the hot water in the storage container will continuously be added or removed during use, causing pressure fluctuations, the existing technology generally adopts a method of direct connection of the balance hole to the atmosphere. This direct connection not only allows dust to enter the container through the balance hole, but also allows heat to be lost through the balance hole. Especially for ultra-large water storage equipment, the area of ​​the balance hole is relatively large, and this heat loss will be particularly significant. If a pressure reducing valve structure is used, it will increase the manufacturing cost. If the pressure reducing valve has quality problems, it will cause the water storage container to burst or collapse, creating a safety hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a heat-insulating breather valve that, through its internal labyrinth design and the static liquid seal formed by condensate, minimizes heat loss, thereby achieving energy saving and cleanliness by maintaining pressure balance in the hot water storage container.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] This invention provides a heat-insulating breathing valve, comprising a dust cover, a conical cover A, a conical cover B, a water collector, and a breathing valve wall. The conical covers A and B are arranged alternately at intervals within the heat-insulating breathing valve, with no less than three layers forming at least three levels of airflow reversal channels. The smaller end of the upper layer extends into the interior of the larger end of the lower layer to one-seventh of its length. The water collector is installed at the smaller end of the conical cover A, and the dust cover is located at the top of the heat-insulating breathing valve.

[0006] Furthermore, the conical shields A and B have their large ends facing upwards and their small ends open.

[0007] Furthermore, the cone angle of the conical cover A and the conical cover B is 60°-110°, and the small end of the conical cover A extends into the conical cover B at a quarter of its length.

[0008] Furthermore, the outer edge of the large end of the conical cover A is welded to the wall of the breather valve, and the weld ensures a seal.

[0009] Furthermore, the conical hood B can be connected to the wall of the breathing valve via a bracket, ensuring unobstructed airflow between them.

[0010] Furthermore, the water collector is installed at the lower part of the small end of the conical cover A via a bracket, and airflow must be ensured between them.

[0011] Furthermore, after the water collector stores water, it ensures that the small end of the conical cover A is submerged more than 5mm below the liquid surface, forming a gas-liquid interface, so that the airflow must pass through the water layer to enter and exit the water tank, thus blocking the direct escape of hot air.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The present invention relates to a heat-insulating breather valve that is vertically installed on the upper part of the heat-insulating water tank and communicates with the inside of the tank. When the heat-insulating water tank is replenished, the liquid level in the tank rises, and the air and water vapor in the tank will flow out through the heat-insulating breather valve. Due to the labyrinth design of the heat-insulating breather valve and the static liquid seal formed by the condensate, the water vapor carrying heat will condense into water droplets on the flow channel wall and flow back to the water collector and the heat-insulating water tank, preventing the heat from being carried away by the water vapor. When the heat-insulating water tank is discharged, the pressure inside the tank decreases, and the atmosphere will enter the heat-insulating water tank through the labyrinth channel of the heat-insulating breather valve, through the static liquid seal formed by the condensate, to balance the air pressure and ensure that the heat-insulating water tank is not sucked down. At the same time, due to the static liquid seal formed by the condensate, dust in the air is adsorbed, ensuring the cleanliness of the heat-insulating water tank. Attached Figure Description

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1:

[0021] A heat-insulating breathing valve includes a dust cover 1, a conical cover A2, a conical cover B3, a water collector 4, and a breathing valve wall 5. The conical covers A2 and B3 are arranged alternately within the heat-insulating breathing valve, in at least three layers, forming at least three levels of airflow reversal channels. The smaller end of the upper layer extends into the larger end of the lower layer to one-seventh of its depth. The water collector 4 is installed at the smaller end of the conical cover A2. The cone angles of the conical covers A and B are 60°-110°. The smaller end of the conical cover A extends into the conical cover B to one-quarter of its depth. The dust cover 1 is located at the top of the heat-insulating breathing valve. The conical hoods A2 and B3 have their large ends facing upwards and their small ends open. The outer edge of the large end of the conical hood A2 is welded to the breather valve wall 5, and the weld is sealed. The conical hood B3 can be connected to the breather valve wall 5 via a bracket, ensuring unobstructed airflow. The water collector 4 is installed at the lower part of the small end of the conical hood A2 via a bracket, ensuring unobstructed airflow. After the water collector 4 stores water, it ensures that the small end of the conical hood A2 is submerged at least 5mm below the liquid surface, forming a gas-liquid interface. This forces airflow to pass through the water layer to enter and exit the water tank, preventing hot air from escaping directly.

[0022] like Figure 1 As shown: When the insulated water tank is replenished, the liquid level in the tank rises, and the air and water vapor inside the tank will flow out through the insulated breather valve. Due to the labyrinth design of the insulated breather valve and the static liquid seal formed by the condensate, the water vapor carrying heat will flow upward along the gap between the conical cover B3 and the breather valve wall 5. When the water vapor flows to the outer wall of the conical cover A2, because the conical cover A2 and the breather valve wall 5 are welded and sealed, the water vapor will flow back towards... Figure 1 As shown in area A; simultaneously, water vapor will also flow directly upwards along the inner cavity of the conical shroud B3, encountering the returning water vapor in area A. Due to the opposite airflow direction, the airflow is blocked, accelerating the condensation of water vapor on the channel wall. Afterwards, the water vapor will continue to flow upwards through the condensate 6 in the water collector 4. The condensate 6 absorbs heat from the water vapor, further storing energy. Through multiple labyrinth stages and static liquid seals, water vapor will continuously precipitate in the form of condensate. Due to the high specific heat capacity of water, increasing the precipitation of condensate will greatly reduce heat loss. The water vapor flow direction is as follows... Figure 1 As indicated by the solid arrow.

[0023] like Figure 2As shown: When water is discharged from the insulated water tank, the liquid level in the tank drops. External air enters the tank through the labyrinth design of the insulated breather valve and the static liquid seal formed by the condensate. During this flow, dust in the air is absorbed by the condensate 6 in the water collector 4. Simultaneously, the condensate 6 heats the supplied air, allowing energy to be carried back into the insulated water tank. The condensate 6, releasing heat, prepares for the next exhaust cycle. This cycle repeats, reducing heat loss. Dust in the external air is also absorbed by the condensate 6 as it flows through it. The external air flow direction is as follows... Figure 2 As indicated by the dashed arrow.

[0024] Similarly, the insulated water tank can also be used as a storage device for volatile hazardous chemicals. The insulated breather valve recovers and seals volatile hazardous chemicals by releasing moisture from the water vapor. At the same time, because the airflow direction in area A shown in the figure is opposite, the airflow velocity is reduced. The superposition of multiple areas A increases the pressure inside the insulated water tank. After pressurization, the volume of the volatile hazardous chemical gas phase is compressed, resulting in an increase in the concentration of vapor molecules and the increase in partial pressure. This reduces the evaporation of the liquid and the possibility of the hazardous chemicals being released into the atmosphere after evaporation, thus avoiding environmental pollution.

[0025] Finally: The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
