Abstract
The invention discloses an anti-condensation nitrogen gas tank which comprises a nitrogen gas conveying pipe connected with the interior of a tank body of the nitrogen gas tank, wherein a first temperature sensor is arranged at the output end, located in the tank body, of the nitrogen gas conveying pipe; a second temperature sensor is arranged in the position, away from the output end of the nitrogen gas conveying pipe, in the tank body; a nitrogen gas heating device is arranged on the nitrogen gas conveying pipe; and the nitrogen gas heating device, the first temperature sensor and the second temperature sensor are connected to a heating controller respectively. The nitrogen gas is heated to the temperature of the interior of the tank body, the temperature difference is prevented, so that the condensation phenomenon is prevented, and the safety of stored materials is guaranteed.
Description
Technical field
The present invention relates to antisweat nitrogen cabinet.
Background technique
After the general employing in the nitrogen source liquid nitrogen gasification of nitrogen cabinet, be filled with in case, play and reduce the effect of oxygen content in humidity, case in case.Known, in the process of nitrogen from liquid to gas, can absorb a large amount of energy, so nitrogen temperature before entering casing is lower, the nitrogen that temperature is lower contacts with the air of normal temperature in case, will produce dewfall phenomenon, causes article in case run into the globule and damage.
Summary of the invention
The object of the present invention is to provide a kind of antisweat nitrogen cabinet, it can prevent that nitrogen from contacting owing to producing the phenomenon of dewfall compared with the large temperature difference with air in case, guarantees the safety of storage material.
For achieving the above object, technological scheme of the present invention is a kind of antisweat nitrogen cabinet of design, comprises and the inner nitrogen delivery pipe being connected of nitrogen cabinet cabinet;
The output terminal of described nitrogen delivery pipe in cabinet inside is provided with the first temperature transducer;
Described cabinet inside is provided with the second temperature transducer away from the position of nitrogen delivery pipe output terminal;
Described nitrogen delivery pipe is provided with nitrogen heating equipment;
Described nitrogen heating equipment, the first temperature transducer, the second temperature transducer are connected to respectively heating controller.
Preferably, described nitrogen delivery pipe is provided with flowmeter.
Preferably, described nitrogen delivery pipe is provided with throttle valve.
Preferably, described nitrogen delivery pipe is provided with one-way valve.
The first temperature transducer can detect nitrogen outlet temperature, and signal is passed to heating controller.
The second temperature transducer can detect the temperature inside the box, and signal is passed to heating controller.
Nitrogen heating equipment is housed on nitrogen delivery pipe, by heating controller, comes controller to heat.
When nitrogen outlet temperature being detected lower than the temperature inside the box, heating controller starts heating equipment, and when nitrogen outlet temperature being detected higher than the temperature inside the box, heating controller can heating-stopping apparatus heating.
By nitrogen is heated, be heated to the temperature inside the box, prevent that the temperature difference from producing, thereby avoid the generation of dewfall phenomenon, guarantee the safety of storage material.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technological scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
The concrete technological scheme of implementing of the present invention is:
As shown in Figure 1, a kind of antisweat nitrogen cabinet, comprises and the inner nitrogen delivery pipe 2 being connected of nitrogen cabinet cabinet 1;
The output terminal of described nitrogen delivery pipe 2 in cabinet 1 inside is provided with the first temperature transducer 3;
Described cabinet 1 inside is provided with the second temperature transducer 4 away from the position of nitrogen delivery pipe 2 output terminals;
Described nitrogen delivery pipe 2 is provided with nitrogen heating equipment 5;
Described nitrogen heating equipment 5, the first temperature transducer 3, the second temperature transducer 4 are connected to respectively heating controller (on figure for illustrating).
Described nitrogen delivery pipe 2 is provided with flowmeter 6.
Described nitrogen delivery pipe 2 is provided with throttle valve 7.
Described nitrogen delivery pipe 2 is provided with one-way valve 8.
The first temperature transducer 3 can detect nitrogen outlet temperature, and signal is passed to heating controller.
The second temperature transducer 4 can detect the temperature inside the box, and signal is passed to heating controller.
When nitrogen outlet temperature being detected lower than the temperature inside the box, heating controller starts heating equipment, and when nitrogen outlet temperature being detected higher than the temperature inside the box, heating controller can heating-stopping apparatus heating.
By nitrogen is heated, be heated to the temperature inside the box, prevent that the temperature difference from producing, thereby avoid the generation of dewfall phenomenon, guarantee the safety of storage material.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
