As shown in fig. 1, an embodiment of the present invention provides an exhaust system including:
a hydrogen detection sensor 101, a control device 102, an air inlet device 103 and an air exhaust device 104; wherein,
the hydrogen detection sensor 101 is used for collecting hydrogen concentration information of a designated space where storage batteries are densely arranged;
the control device 102 is configured to determine a hydrogen concentration value of the designated space according to the hydrogen concentration information acquired by the hydrogen detection sensor 101, and control the air intake device 103 and the air exhaust device 104 to be turned on when the determined hydrogen concentration value reaches a first preset threshold value;
the air inlet device 103 is used for driving air in the external environment to enter the designated space when the air inlet device is started;
and the exhaust device 104 is used for driving the air mixed with the hydrogen in the designated space to be exhausted to the external environment when the device is started.
As shown in the embodiment of figure 1, the system is composed of a hydrogen detection sensor, a control device, an air inlet device and an air exhaust device; the hydrogen detection sensor can collect hydrogen concentration information of an appointed space in which the storage battery is densely arranged, the control device can determine the hydrogen concentration value of the appointed space according to the collected hydrogen concentration information, when the hydrogen concentration value reaches a first preset threshold value, the air inlet device and the air exhaust device are controlled to be opened, the opened air inlet device can drive air in an external environment to enter the appointed space, and the opened air exhaust device can drive air mixed with hydrogen in the appointed space to be exhausted to the external environment, so that the concentration of the hydrogen in the appointed space is reduced, and the appointed space is ensured not to be exploded due to overhigh hydrogen concentration. In conclusion, the control device controls the air inlet device and the air exhaust device if and only if the hydrogen concentration value reaches the first preset threshold value, namely the air inlet device and the air exhaust device are not opened for a long time, so that the situation that explosion is caused due to overhigh hydrogen concentration in the designated space is avoided, and the power consumption is low.
When the concentration (volume concentration) value of hydrogen in a space is between 4.0% and 75.6%, a station reporting phenomenon will occur, and each storage battery densely arranged in the designated space gradually releases hydrogen in the use process, so that the first preset threshold value must be less than 4.0%; meanwhile, in order to enable the hydrogen accumulated in the designated space to be discharged to the external environment in time, a certain safety interval should exist between the first preset threshold and the limit value of 4.0%, so that the hydrogen concentration value of the designated space cannot exceed or even approach to 40% all the time, and the specific value thereof can be adjusted by combining the volume of the designated space and the hydrogen release rate of each storage battery densely deployed in the designated space in the using process, generally, the first preset threshold may be any value between 1.5% and 2%, such as 1.5%, 1.75% or 2%.
It will be understood by those skilled in the art that the designated space herein may specifically be the interior space of a battery compartment/container used in a large-scale data center for densely deploying batteries. Obviously, the exhaust system may also be applied to other service scenarios than large-scale data centers, for example, to the battery compartment of a substation.
In each embodiment of the invention, the hydrogen detection sensor can acquire the hydrogen concentration information of the designated space densely provided with the storage battery in real time, and the control can also determine the hydrogen concentration value of the designated space according to the hydrogen concentration information acquired by the hydrogen detection sensor in real time.
The main components of the air are oxygen, nitrogen and carbon dioxide, the density of the hydrogen is far less than that of the oxygen, the nitrogen and the carbon dioxide, the storage battery is usually arranged at the bottom of the designated space, and after the storage battery releases the hydrogen, the released hydrogen can be gathered to the top area of the designated space in a large quantity, so that the hydrogen concentration of the top area in the designated space is greater than that of the bottom area in the designated space; in order to ensure that the designated space is not exploded due to the high hydrogen concentration in a local area, the exhaust system should be able to accurately detect the hydrogen concentration value in the top area of the designated space, and accordingly, referring to fig. 3, in a preferred embodiment of the present invention, the hydrogen detection sensor 101 is disposed in the top area of the designated space.
Accordingly, in order to ensure that the air mixed with a large amount of hydrogen in the designated space can be preferentially discharged to the external environment, in a preferred embodiment of the present invention, the air intake device 103 is used for driving the air in the external environment into the bottom area of the designated space; and the air exhaust device 104 is used for driving the air in the top area of the designated space in the designated space to be exhausted to the external environment.
Specifically, referring to fig. 2, the air intake device 103 and the air exhaust device 104 may be respectively composed of a plurality of ventilation pipelines and an air inducing module (e.g., a fan) disposed on each ventilation pipeline. Correspondingly, each ventilation pipe 1031 of the air intake device 103 should communicate the bottom region of the designated space with the external environment, so that the air inducing module of the air intake device 103 can drive the air in the external environment to enter the bottom region of the designated space through the ventilation pipe 1031 of the air intake device 103; each ventilation pipe 1041 of the exhaust device 104 should communicate the top area of the designated space with the external environment, so that the air inducing module of the exhaust device 104 can drive the air in the designated space located in the top area of the designated space into the external environment through the ventilation pipe 1041 of the exhaust device 104. Therefore, the air in the top area in the designated space is preferentially discharged, and the hydrogen in the designated space is preferentially discharged so as to rapidly reduce the concentration of the hydrogen in the designated space.
It should be noted that the area enclosed by the black frame lines in fig. 2 represents the designated space, and the pointing direction of each black arrow represents the air flow direction of the corresponding area in the designated space.
In another possible implementation manner, each ventilation pipeline of the air intake device is communicated with the bottom area of the designated space and the external environment, and each ventilation pipeline of the air exhaust device is also communicated with the top area of the designated space and the external environment; in this manner, it is also possible to achieve preferential discharge of air in the top region in the designated space, that is, preferential discharge of hydrogen in the designated space to rapidly reduce the concentration of hydrogen in the designated space.
In order to further reduce the electric quantity consumed by the air intake device and the air exhaust device, the opened air intake device and the opened air exhaust device can be closed when a large amount of hydrogen in the designated space is exhausted, namely the concentration of the hydrogen in the designated space is greatly reduced. The invention specifically provides the following two implementation modes 1 and 2, which specifically realize that when the concentration of hydrogen in a specified space is greatly reduced, the opened air inlet device and the opened air exhaust device are closed.
In implementation mode 1, the control device 102 controls the air intake device 103 and the air exhaust device 104 to be closed when the determined hydrogen concentration value is smaller than a second preset threshold value.
In the implementation mode 2, the control device 102 records the opening time of the air exhaust device 104 after controlling the air exhaust device 104 to be opened, and controls the opened air intake device 103 and the opened air exhaust device 104 to be closed when the opening time reaches the preset time.
In implementation mode 1, the second preset threshold may be adjusted by combining with the volume of the designated space and the hydrogen release rate of each storage battery densely deployed in the designated space during the use process, and generally, the second preset threshold may be any value between 0.5% and 1%, such as 0.5%, 0.75%, or 1%.
In implementation manner 2, the preset duration may be determined by combining the volume of the designated space, the rate of releasing hydrogen gas from each storage battery densely disposed in the designated space during use, and the exhaust rate of the exhaust device when exhausting air to the external environment.
The hydrogen detecting sensor 101 in the embodiments of the present invention includes, but is not limited to, a semiconductor sensor, a pyroelectric sensor, or an optical fiber sensor, as long as it is ensured that it can collect hydrogen concentration information in a specified space, and when the collected hydrogen concentration information is provided to the control device, the control device can accurately determine the hydrogen concentration value in the specified space according to the collected hydrogen concentration information.
For a semiconductor sensor, the semiconductor sensor includes a gas-sensitive material such as metal oxide such as tin oxide, zinc oxide, tungsten trioxide, etc., and a chemical adsorption layer, when the gas-sensitive material adsorbs hydrogen, the hydrogen acts as a donor to release electrons, and the electrons are combined with oxygen ions in the chemical adsorption layer, so that the carrier concentration changes, and a certain functional relationship exists between the change value of the carrier concentration and the hydrogen volume fraction (i.e., hydrogen concentration), so that the change value of the carrier concentration can be provided to a control device as hydrogen concentration information, and the control device can determine a corresponding hydrogen concentration value according to the change value of the carrier concentration.
For a pyroelectric sensor, it includes a substrate, a layer of pyroelectric material deposited on the substrate, and a layer of catalytic metal (e.g., platinum, lead) deposited on a portion of the surface of the pyroelectric material, and electrodes are led out of the catalytic metal layer, the pyroelectric thin film layer (a portion of the pyroelectric material without catalytic metal). When the thermoelectric sensor is exposed in an environment containing hydrogen, hydrogen and oxygen react to generate water vapor and release heat under the action of catalytic metal, so that the temperature of one end of the thermoelectric material deposited with the catalytic metal is high to form a hot end, the temperature of the other end without the catalytic metal is low to form a cold end, the thermoelectric power generation effect of the thermoelectric material can convert the temperature difference between the hot end and the cold end into thermoelectric potential, the thermoelectric potential is output to a control device in the form of an electric signal, and the control device can determine the hydrogen concentration value according to the received electric signal.
For the optical fiber sensor, palladium coated on the surface of an optical fiber in the optical fiber sensor expands in hydrogen to change the effective optical path length of the optical fiber and further generate a changed optical signal, and the control device can determine the hydrogen concentration value according to the optical signal.
Generally, since the hydrogen gas in the designated space is often discharged when the hydrogen gas concentration value is far below the explosion limit (i.e. far below 4.0%), the above sensors can satisfy the technical solution provided by the embodiment of the present invention in theory. However, the hydrogen concentration information provided by the semiconductor sensor and the pyroelectric sensor are both electrical signals, which may generate electric sparks, and have a relatively high safety risk, so in order to further reduce the safety risk, the hydrogen detection sensor may specifically adopt an optical fiber sensor.
In an embodiment of the present invention, the exhaust system further includes: a hydrogen recovery device (not shown in the drawings); wherein,
the hydrogen recovery device is connected with the exhaust device 104;
the exhaust device 104 is used for driving the air in the designated space to be exhausted to the hydrogen recovery device when the device is started;
the hydrogen recovery device is configured to filter the air discharged from the exhaust device 104 to retain hydrogen, and discharge the filtered air to the external environment.
In this embodiment, through filtering the hydrogen that the ware carried in order to preserve to exhaust device exhaust air, the hydrogen of being convenient for follow-up to hydrogen recovery unit retention is retrieved and is recycled, avoids simultaneously directly discharging a large amount of hydrogen and causes the pollution to the atmosphere in the external environment.

304, driving air in the external environment to enter the designated space by using the opened air inlet device;
and 305, driving the air mixed with the hydrogen in the appointed space to be exhausted to the external environment by utilizing the opened exhaust device.
