The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus consistent with certain aspects of the present application, as detailed in the appended claims.
Because foods such as vegetables and fruits have a certain fresh-keeping period, but in a general environment, the fresh-keeping period of the vegetables and fruits cannot meet the requirements of people, the fresh-keeping period of the vegetables and fruits needs to be prolonged, the fresh-keeping period is prolonged by adopting a refrigeration mode in a general mode, but the time prolonged by the method is still limited.
Because the vegetables and fruits can generate metabolic activity in the storage process, in order to prolong the preservation period of the vegetables and fruits, the storehouse for storing the vegetables and fruits can be deoxidized and decarbonized by adopting an air-conditioning mode so as to reduce the metabolic activity and the respiratory consumption of the vegetables and fruits in the storage process, thereby prolonging the preservation period of the vegetables and fruits. The existing gas-regulating device can only remove one gas, for example, only oxygen or carbon dioxide, and if a good gas-regulating fresh-keeping effect is to be achieved, a plurality of gas-regulating devices capable of removing different gases are required to be used for gas regulation, which increases the cost of fresh-keeping.
In order to solve the above technical problem, the present application provides a modified atmosphere system, which is described below by way of example.
Example one
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air conditioning system according to an embodiment of the present application.
As shown in fig. 1, the modified atmosphere system provided in this embodiment may include: the system comprises an oxygen removal device 1, a carbon dioxide removal device 2, a gas circulation device 3, a vacuum pump 4, an air-conditioned cold store air inlet valve 5 and an air-conditioned cold store air outlet valve 6;
a first inlet 11, a first outlet 12 and a second outlet 13 of the oxygen removal device; the carbon dioxide removal device is provided with a second inlet 21, a third outlet 22 and a fourth outlet 23; the gas circulation device is provided with an air inlet 31;
the first inlet and the second inlet are connected with one end of a gas circulating device, and the other end of the gas circulating device is connected with a gas outlet valve of the gas-conditioned cold store, so that the gas circulating device pumps gas in the gas-conditioned cold store out through the gas outlet valve of the gas-conditioned cold store and conveys the gas to an oxygen removing device for deoxidation or a carbon dioxide removing device for decarbonization; the air-conditioned cold store is used for storing articles to be preserved;
the first outlet and the third outlet are connected with an air inlet valve of the controlled atmosphere storage, so that the deoxidized gas in the oxygen removing device or the decarbonized gas in the carbon dioxide removing device enters the controlled atmosphere storage through the air inlet valve of the controlled atmosphere storage;
one end of the vacuum pump is connected with the second outlet, and the other end of the vacuum pump is communicated with air, so that the oxygen removal device is pumped to be vacuum to clean the oxygen removal device;
the fourth outlet is in communication with the atmosphere such that the gas circulation device draws atmospheric air into the carbon dioxide removal device through the air inlet and out the fourth outlet to effect purging of the carbon dioxide removal device.
Because the first inlet and the second inlet are connected with one end of the gas circulating device, and the other end of the gas circulating device is connected with the gas outlet valve of the gas-conditioned cold store, the gas circulating device pumps out the gas in the gas-conditioned cold store through the gas outlet valve of the gas-conditioned cold store and conveys the gas to the oxygen removing device for deoxidation or the carbon dioxide removing device for decarbonization; connecting the first outlet and the third outlet with an air inlet valve of the controlled atmosphere storage to ensure that the deoxidized gas in the oxygen removing device or the decarbonized gas in the carbon dioxide removing device enters the controlled atmosphere storage through the air inlet valve of the controlled atmosphere storage; one end of the vacuum pump is connected with the second outlet, and the other end of the vacuum pump is communicated with air, so that the oxygen removal device is pumped to be vacuum to clean the oxygen removal device; and communicating the fourth outlet with the atmosphere, so that the gas circulating device pumps air in the atmosphere into the carbon dioxide removing device through the air inlet and escapes from the fourth outlet to clean the carbon dioxide removing device. Therefore, the controlled atmosphere system can not only realize deoxidation of the controlled atmosphere store, but also realize decarburization of the controlled atmosphere store, and avoids the problem of controlled atmosphere by using a plurality of devices, thereby reducing the controlled atmosphere cost.
By using the controlled atmosphere system in this embodiment, the controlled atmosphere storage may be deoxygenated first, the inlet valve and the outlet valve of the controlled atmosphere storage may be opened, the first inlet and the first outlet are set in the ventilated state, the gas circulation device is operated, so that the gas in the controlled atmosphere storage is pumped into the oxygen removal device through the first inlet via the outlet valve of the controlled atmosphere storage to be deoxygenated, and then enters the controlled atmosphere storage from the inlet valve of the controlled atmosphere storage via the first outlet. And then when the carbon dioxide is removed, the first inlet and the first outlet are kept in a closed state, the air inlet valve and the air outlet valve of the controlled atmosphere storage are opened, the second inlet and the third outlet are set in an air-ventilating state, and the gas circulating device is operated, so that the gas in the controlled atmosphere storage passes through the air outlet valve of the controlled atmosphere storage, enters the carbon dioxide removing device through the second inlet to remove the carbon dioxide, then passes through the third outlet and then enters the controlled atmosphere storage through the air inlet valve of the controlled atmosphere storage. Generally, the oxygen removal process or the carbon dioxide removal process is controlled by detecting the oxygen concentration and the carbon dioxide concentration in the gas in the controlled atmosphere storage, i.e., the removal of oxygen is stopped when the oxygen concentration in the controlled atmosphere storage is lower than a preset value, and the removal of carbon dioxide is stopped when the carbon dioxide concentration in the controlled atmosphere storage is lower than a preset value.
Because the removal of oxygen and carbon dioxide in the controlled atmosphere storage needs a long time, the removal amount of the oxygen removal device and the carbon dioxide removal device is limited, air in the controlled atmosphere storage cannot be removed to a desired state at one time, during the period, the oxygen removal device can reach a deoxygenation saturated state, and in the state, the oxygen removal device cannot continue to be deoxygenated; similarly, the carbon dioxide removing device is saturated and cannot remove carbon dioxide continuously, at this time, the air outlet valve and the air inlet valve of the controlled atmosphere storage are closed, the air inlet of the gas circulating device is opened, the fourth outlet is opened, the gas circulating device blows air into the carbon dioxide removing device through the air inlet and the second inlet, and high-concentration carbon dioxide attached to the air is blown out from the fourth outlet, so that the carbon dioxide removing device is cleaned.
Example two
Referring to fig. 2, fig. 2 is a schematic structural diagram of an air conditioning system according to a second embodiment of the present application.
As shown in fig. 2, the modified atmosphere system provided by this embodiment can remove oxygen and carbon dioxide from the modified atmosphere storage only by two modified atmosphere tanks. The controlled atmosphere system shown in fig. 2 is exemplified by using an air inlet valve and an air outlet valve of a controlled atmosphere storage as two-way valves, and specifically, on the basis of the first embodiment, the carbon dioxide removing device of the present embodiment is further provided with a fifth outlet 24, and the fifth outlet is connected with one end of a vacuum pump, so that the vacuum pump pumps the carbon dioxide removing device to vacuum; the oxygen removal device comprises a first deoxygenation tank 14, a first valve 15, a second valve 16 and a third valve 17; the carbon dioxide removal device comprises a first decarbonization tank 25, a fourth valve 26, a fifth valve 27, a sixth valve 28 and a seventh valve 29; one end of the first valve is communicated with the first deoxidizing tank, and one end of the fourth valve is communicated with the first decarbonizing tank; the other end of the first valve is a second outlet; the other end of the fourth valve is a fifth outlet; one end of the second valve is communicated with the first deoxidizing tank, one end of the fifth valve is communicated with the first decarbonizing tank, and the other end of the second valve is a first inlet; the other end of the fifth valve is a second inlet; one end of the third valve is communicated with the first deoxidizing tank, and one end of the sixth valve is communicated with the first decarbonizing tank; the other end of the third valve is a second outlet, and the other end of the sixth valve is a third outlet; one end of the seventh valve is communicated with the first decarburization tank, and the other end of the seventh valve is a fourth outlet.
In this embodiment, when performing deoxidation, the air inlet and outlet valve, the second valve, the third valve and the air inlet valve of the controlled atmosphere storage are opened, and other valves are kept closed, and the gas circulation device is operated, and the gas circulation device will pump out air in the controlled atmosphere storage, and return to the controlled atmosphere storage through the air inlet and outlet valve of the controlled atmosphere storage, the first valve, the first deoxygenation tank, the third valve and the air inlet valve of the controlled atmosphere storage in sequence, wherein the first deoxygenation tank is responsible for deoxygenating passing gas.
When the first deoxygenation tank is saturated, the fifth valve, the seventh valve and the air inlet of the gas circulation device are opened first, and then the second valve and the third valve are closed, so that the gas circulation device sucks air from the air inlet and returns to the atmosphere through the fifth valve and the seventh valve, the gas circulation device can be ensured to continuously operate, and damage caused by frequent starting and stopping of the gas circulation device is avoided. After the gas circulation device is ensured to continuously operate, the inlet and outlet gas valve, the second valve, the third valve and the inlet valve of the controlled atmosphere storage are closed, the first valve is opened, the vacuum pump is operated, the first deoxygenating tank is pumped to a vacuum state or a near vacuum state reaching a preset gas pressure value (certainly, the confirmation of the vacuum state can be limited by the working time of the vacuum pump because the volume of the first deoxygenating tank is fixed), after the state is reached, the fourth valve is opened, the inlet and outlet gas valve, the second valve, the third valve and the inlet valve of the controlled atmosphere storage are opened, the fifth valve and the air inlet of the gas circulation device are closed, so that the vacuum pump pumps the gas in the first decarboning tank, and the first deoxidizing tank continues to perform the deoxidizing operation on the controlled atmosphere storage, and the operation is circulated in such a way, until the oxygen concentration of the controlled atmosphere storage is lower than a preset value, the deoxidizing process is stopped.
When the controlled atmosphere system of the embodiment is used for removing carbon dioxide, the outlet valve, the fifth valve, the third valve and the inlet valve of the controlled atmosphere storage are opened, and other valves are kept closed, the gas circulating device is operated, so that the gas in the controlled atmosphere storage circulates through the outlet valve, the fifth valve, the first decarbonization tank, the third valve and the inlet valve of the controlled atmosphere storage in sequence, the first decarbonization tank adsorbs carbon dioxide in the gas, substances adsorbing carbon dioxide in the gas can be mainly activated carbon, and the principle of removing carbon dioxide and the structure of the first decarbonization tank constructed according to the principle of removing carbon dioxide are the prior art and are not necessary technical characteristics for solving the technical problems provided by the application, so the principle of removing carbon dioxide and the structure of the first decarbonization tank are not explained here, and when the embodiment of the application is implemented, the existing decarbonization tank can be directly used.
When the first decarburization tank reaches a saturated state, the air inlet and the seventh valve of the gas circulation device are opened, the air outlet valve, the third valve and the air inlet valve of the controlled atmosphere storage are closed, the gas circulation device flushes the first decarburization tank by using air in the atmosphere, carbon dioxide attached to the inside of the first decarburization tank is flushed away, after the first decarburization tank is cleaned, the air outlet valve, the third valve and the air inlet valve of the controlled atmosphere storage are opened, the seventh valve and the air inlet are closed, carbon dioxide in the gas in the controlled atmosphere storage is removed, and the process is circulated until the concentration of the carbon dioxide in the controlled atmosphere storage is lower than a preset value.
The saturated state can be identified in a timing mode, and the saturated state can be judged by timing deoxidation or decarburization because the internal structures and the volumes of the first deoxygenating tank and the first decarboning tank are fixed and the adsorption capacities of the first deoxygenating tank and the first decarboning tank are determined.
The controlled atmosphere system provided by the embodiment can be applied to a plurality of controlled atmosphere storehouses, wherein the air inlet valve of the controlled atmosphere storehouses comprises a plurality of sub air inlet valves, and the air outlet valve of the controlled atmosphere storehouses comprises a plurality of sub air outlet valves; each air-conditioned cold store is provided with a pair of sub air outlet valves and sub air inlet valves.

Of course, when the sub gas outlet valve is a three-way valve or a two-way valve, the internal structure of the corresponding gas circulation device is also different, and the following description is made in order.
When the sub gas outlet valve is a two-way valve, the gas circulating device comprises a first fan 32, an eighth valve 33 and a ninth valve 34; the first fan has a first fan inlet and a first fan outlet; one end of the eighth valve and one end of the ninth valve are both communicated with the inlet of the first fan; the other end of the eighth valve is communicated with each sub air outlet valve, and the other end of the ninth valve is an air inlet; the first fan outlet is communicated with the first inlet and the second inlet respectively.
