Description

Technical Field

[0001] The present invention relates to the technical field of heat storage equipment, in particular to a heat-insulating breathing valve. Background Art

[0002] Hot water storage technology is widely used in daily life, industrial production and new energy fields. Its core goal is to reduce heat loss, improve storage efficiency and ensure safe use. Because the hot water in the water storage container will be continuously added or reduced during use, pressure fluctuations will occur. The existing technology generally adopts a balance hole directly connected to the atmosphere. The direct-through method not only causes dust to enter the container through the balance hole, but also heat will be lost through the balance hole. Especially for super-large water storage equipment, the area of the balance hole is relatively large, and this heat loss will be particularly huge. If a pressure reducing valve structure is used, the production cost will increase. If there is a quality problem with the pressure reducing valve, it will cause the water storage container to burst or deflate, causing a safety hazard. Summary of the Invention

[0003] The purpose of the present invention is to provide a thermal insulation breathing valve, which, through the internal maze design and the static liquid seal formed by condensed water, can block the loss of heat to the maximum extent, so as to achieve the purpose of energy saving and cleaning while maintaining the pressure balance of the hot water storage container and reducing the heat loss to a minimum.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:

[0005] The present invention provides a thermal insulation breathing valve, comprising a dust cover, a conical cover A, a conical cover B, a water collector, and a breathing valve wall. The conical cover A and the conical cover B are alternately arranged in intervals within the thermal insulation breathing valve, with no less than three layers, forming at least three levels of airflow return channels, with the small end of the upper layer extending into one-seventh of the interior of the large end of the lower layer. The water collector is installed at the small end of the conical cover A, and the dust cover is located at the top of the thermal insulation breathing valve.

[0006] Furthermore, the large ends of the conical covers A and B are upward and the small ends are open.

[0007] Furthermore, the cone angles of the cone cover A and the cone cover B are 60°-110°, and the small end of the cone cover A extends into the cone cover B by a quarter.

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

[0009] Furthermore, the conical cover B can be connected to the breathing valve wall through a bracket, and unimpeded airflow must be ensured therebetween.

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

[0011] Furthermore, after the water collector stores water, ensure that the small end of the conical cover A is immersed more than 5 mm below the liquid level to form a gas-liquid interface, so that the air flow needs to pass through the water layer to enter and exit the water tank, blocking the direct escape of hot air.

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

[0013] The thermal insulation breathing valve of the present invention is vertically installed on the upper part of the thermal insulation water tank and is communicated with the inside of the water tank. When the thermal insulation water tank is replenished with water, the liquid level in the water tank rises, and the air and water vapor in the water tank will flow out through the thermal insulation breathing valve. Due to the maze design of the thermal insulation breathing valve and the static liquid seal formed by the condensed water, the water vapor carrying heat will condense into water droplets on the wall surface of the flow channel and flow back to the water collector and the thermal insulation water tank, avoiding the heat being carried away by the water vapor; when the thermal insulation water tank discharges water, the pressure in the water tank decreases, and the atmosphere will pass through the maze channel of the thermal insulation breathing valve, pass through the static liquid seal formed by the condensed water, and enter the thermal insulation water tank to balance the air pressure, ensuring that the thermal insulation water tank is not sucked flat. At the same time, due to the static liquid seal formed by the condensed water, the dust in the air is adsorbed, ensuring the cleanliness of the thermal insulation water tank.

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1:

[0021] A thermal insulation breathing valve includes a dust-proof cover 1, a conical cover A 2, a conical cover B 3, a water collector 4, and a breathing valve wall 5. The conical cover A 2 and the conical cover B 3 are arranged alternately at intervals in the thermal insulation breathing valve, with no less than 3 layers, forming at least 3 levels of air flow return channels. The small end of the upper layer extends into the large end of the lower layer by one-seventh. The water collector 4 is installed at the small end of the conical cover A 2. The cone angles of the conical cover A and the conical cover B are 60° - 110°. The small end of the conical cover A extends into the conical cover B by one-fourth. The dust-proof cover 1 is located at the top of the thermal insulation breathing valve. The large ends of the conical cover A 2 and the conical cover B 3 face upward, and the small ends are open. The outer edge of the large end of the conical cover A 2 is welded to the breathing valve wall 5, and the weld ensures sealing. The conical cover B 3 can be connected to the breathing valve wall 5 through a bracket, and the air flow must be unobstructed between them. The water collector 4 is installed at the lower part of the small end of the conical cover A 2 through a bracket, and the air flow must be unobstructed between them. After the water collector 4 stores water, it ensures that the small end of the conical cover A 2 is immersed more than 5 mm below the liquid level, forming a gas-liquid interface, so that the air flow needs to pass through the water layer to enter and exit the water tank, blocking the direct escape of hot air.

[0022] As Figure 1 shown: When the thermal insulation water tank is replenished with water, the liquid level in the water tank rises, and the air and water vapor in the water tank will flow out through the thermal insulation breathing valve. Due to the maze design of the thermal insulation breathing valve and the static liquid seal formed by the condensed water, the water vapor carrying heat will flow upward along the gap between the conical cover B 3 and the breathing valve wall 5. When the water vapor flows to the outer wall of the conical cover A 2, since the conical cover A 2 is welded and sealed with the breathing valve wall 5, the water vapor will then turn back and flow towards Figure 1 the A area shown; at the same time, the water vapor will also directly flow upward along the inner cavity of the conical cover B 3 and meet the turning-back water vapor in the A area. Due to the opposite directions of the air flows, the flow of the air is blocked, accelerating the condensation of the water vapor on the wall surface of the flow channel. Then the water vapor will continue to flow upward through the condensed water 6 in the water collector 4. The condensed water 6 absorbs the heat in the water vapor and further stores energy. After passing through multiple mazes and static liquid seals like this, the water vapor will continuously precipitate in the form of condensed water. Since the specific heat capacity of water is relatively high, increasing the precipitation of condensed water will greatly reduce the heat loss. The flow direction of the water vapor is as shown by the solid line arrow in Figure 1

[0023] As Figure 2 ​As shown: When water flows out of the heat preservation water tank, the liquid level in the tank drops, and external air will enter the interior through the maze design of the heat preservation breathing valve and the static liquid seal formed by the condensed water. During the flowing process, the dust in the air will be absorbed by the condensed water 6 in the water collector 4. At the same time, the condensed water 6 will heat the replenished air, so that the energy is re-introduced into the heat preservation water tank. At this time, the condensed water 6 that releases heat is prepared to absorb heat for the next exhaust cycle. By repeating this cycle, the heat loss is reduced, and the dust in the external air is also adsorbed by the condensed water 6 when flowing through the condensed water 6. The flow direction of the external air is as Figure 2 shown by the dotted arrow.

[0024] By the same principle: The heat preservation water tank can also be used as a storage device for volatile hazardous chemicals. The heat preservation breathing valve realizes the recovery and sealing of volatile hazardous chemicals by separating the water in the water vapor. At the same time, due to the opposite air flow direction in area A shown in the figure, the air flow velocity is reduced. The effect of superimposing multiple areas A makes the pressure in the heat preservation water tank increase. After pressurization, the gas phase volume of the volatile hazardous chemicals will be compressed, resulting in an increase in the vapor molecule concentration and partial pressure, reducing the liquid volatilization, and reducing the possibility of the volatile hazardous chemicals escaping into the atmosphere after volatilization, thus avoiding environmental pollution.

[0025] Finally: The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
