Description

[Detailed description of the invention] The present invention aims to control the concentration of ethylene gas (C2H4) in the cooling chamber in a gas cooling device that stores vegetables, fruits, etc. by filling carbon dioxide gas in the cooling chamber. This paper relates to improvements to ethylene scrubbers for adsorbing excess ethylene gas in indoor rooms.

The purpose of this invention is to adsorb and remove ethylene gas from a gas cooling room using simple piping by using the carbon dioxide scrubber pipe line that adsorbs and removes carbon dioxide from the gas cooling room. To this end, this system is characterized by the provision of an ethylene scrubber in the middle of the pipe line that communicates the gas cooling chamber with the carbon dioxide scrubber loaded with slaked lime.

Next, an example of the implementation will be explained in detail according to the drawings. In FIG. This is a normal refrigerator (or cold room) that can be maintained at a low temperature near zero using the device 2.

3, the above-mentioned normal cooling room 1 is for gas cooling,
Since it is difficult to maintain airtightness in order to create an airtight gas cooling room, an airtight room is installed inside the normal cooling room 1 to serve as a gas cooling room. ,
An airtight sheet 30 or film made of a synthetic resin material is formed into a mosquito net shape and hung.
A circumferential groove 3 for installing or disposing the hem of the refrigerator on the floor surface of the cooling room 1.
1, and the water filled in the circumferential groove 31 forms an airtight chamber inside.

4 is a carbon dioxide gas scrubber connected to the gas cooling chamber (airtight chamber 3), and its main body 40 is loaded with slaked lime.
A base plate 44 and 1 equipped with a circumferential WIt43 that fills the periphery with water;
It is formed by a slaked lime stacking platform 45 which is formed into a tiered shape and placed on the platform 44, and a cover 46 which is formed into an airtight cap shape so as to be placed over it and whose hem falls into the circumference 443. The circulation is connected to the airtight chamber 3 provided in the cooling chamber 1 through piping consisting of a suction side pipe 41 provided on the base plate 44 and an inlet side pipe 42 provided on the cover 46. The piping is connected to form a passage, and the piping is provided with a solenoid valve 47 and a blower fan 48, as shown in FIG.

5 adsorbs ethylene gas generated from vegetables and fruits charged in the gas cooling chamber (airtight chamber 3) or ethylene gas sealed in the gas cooling chamber 3 for accelerating ripening. , an ethylene scrubber installed to control the concentration of ethylene gas in the gas cooling chamber 3 to a predetermined value, and an airtight tank 5 equipped with a charging port 51 that can be opened and closed.
Activated carbon 52 is charged into the inner cavity of the tank 50, and appropriate piping leading to the inner cavity of the tank 50 is connected to the gas cooling chamber 3, and the gas extracted from the gas cooling chamber 3 via the piping is , the ethylene gas in the gas is adsorbed by the activated carbon 52 by contacting the activated carbon, and the passed gas is returned to the gas cooling chamber 3, thereby adsorbing the ethylene gas in the gas cooling chamber 3'.・As for removing it,
Although it is the same as the conventionally known one, the tank 50 in which the activated carbon 52 is loaded is disposed in the middle of the piping 42 of the carbon dioxide scrubber 4, as shown in FIG. Gas cooling chamber 3 via piping 4
It is connected to form a circulation path, and as a result,
When the carbon dioxide scrubber 4 is operated to cause the gas in the gas cooling chamber 3 to return to the gas cooling chamber 3 through the lumen of the main body 40 of the carbon dioxide scrubber 4, the gas is transferred to the ethylene scrubber. It is arranged so that it passes through the tank 50 of No. 5.

Furthermore, as shown in FIG. 4, the ethylene scrubber 5 has a charging port 51 of its tank 50.
The inner cylinder 56 that accommodates the activated carbon 52 is left wide open so that it can be inserted and removed freely, and the lid 55, which can be opened and closed by releasing the engagement of the locking tools 53 and 54, is removed and the charging port 51 is opened.
By opening the activated carbon 52, the inner cylinder 56 that accommodates the activated carbon 52 can be loaded and removed in the form of a cartridge.
Replacement and regeneration of the inner cylinder 56 is carried out by holding the grip part 57 and removing and installing the inner cylinder 56.

In the illustrated embodiment, reference numeral 58 indicates a vent hole provided on the peripheral wall of the inner cylinder 56, and reference numeral 59 indicates an airtight backing provided around the periphery of the charging port 51 of the tank 50.

Next, to explain the function and effect, the ethylene scrubber in the gas cooling device according to the present invention constructed as described above has 1, a tank 50 filled with activated carbon 52 that adsorbs ethylene gas, and a tank 50 which is used to remove carbon dioxide from the gas cooling chamber 3. A gas cooling chamber 3 is installed in the middle of the piping of a carbon dioxide gas scrubber 4 installed to control the concentration, and the gas circulates through the carbon dioxide gas scrubber 4 when the carbon dioxide gas scrubber 4 is operated. The gas inside the tank 5 filled with activated carbon 52
Since the ethylene scrubber 5 can be incorporated into a gas cooling device using simple piping, ethylene gas can be adsorbed and removed at the same time as carbon dioxide gas is adsorbed. This makes operation and control easier, and by allowing the gas adsorbing carbon dioxide to flow into the ethylene scrubber, the adsorption efficiency of activated carbon can be improved.

Moreover, the tank 50 is the main body 40 of the carbon dioxide scrubber 4.
Since the activated carbon loaded in the tank 50 is separated from the tank 50, it becomes easy to take out the activated carbon loaded in the tank 50 for replacement or regeneration.
