Abstract

The utility model provides an easy-deicing air-bath gasifier. With the adoption of the gasifier, an upper fin of the air-bath gasifier is not easy to be iced up, even though the upper fin is iced up, the ice can be removed easily. The gasifier comprises a liquid feeding tube, a fin heat-exchange tube and a gas discharging tube and is characterized in that the fin heat-exchange tube is formed by connecting and communicating heat-exchange tube segments with different fins, and the heat-exchange tube segments are arranged according to the less-to-more sequence of fin number.

Description

Ice-easy-removing air-bathing gasifier

(1) technical field

The utility model relates to a kind of air-bathing gasifier device, is specially ice-easy-removing air-bathing gasifier.

(2) background technology

The cryogenic media that low-temperature storage tank attracts, enter the air-bathing gasifier heating and gasifying, because the liquid medium initial temperature reaches subzero about 196 ℃, fin on the heat exchanger tube of air-bathing gasifier is generally 12, and fin is more, and cryogenic media absorbs the heat in the atmosphere in this tube side, environment temperature around it is fallen morely, add on the tube side surface of its inlet of fin to have moisture in the air, thus can be on heat exchanger tube condenses easily thick ice sheet, the heating vaporization effect is sharply descended.

(3) summary of the invention

At above-mentioned defective, the utility model provides ice-easy-removing air-bathing gasifier, and it can accomplish that finned tube is not-easy-to-freeze on the air-bathing gasifier, also very easily removes even freeze.

Its technical scheme is as follows: it comprises feed tube, fin heat exchange pipe, escape pipe, it is characterized in that: described fin heat exchange pipe connects conducting by the different heat exchange pipeline section of number of fins by tube connector and forms, and described heat exchange pipeline section is by fin number being disposed in order from less to more.

It is further characterized in that: described fin heat exchange pipe by with the heat exchange pipeline section of 4 fins, with the heat exchange pipeline section of 8 fins, with between the heat exchange pipeline section of 12 fins by the tube connector conducting that is connected in series successively.

After the utility model adopts said structure, because fin heat exchange pipe is the structure of different fin numbers, cryogenic media enters the air-bathing gasifier heating and gasifying, and the heat exchanger tube of the state that easily freezes in its porch adopts less fin structure, because fin is few, air flow property around it is big, and environment temperature is just fallen fewly, and is not-easy-to-freeze, even if moisture is more in the atmosphere, Shi Erhui ties ice sheet on the finned tube surface, but because this finned tube fin number is few, freezes and also can conveniently remove; Along with medium temperature progressively improves, the heat exchanger tube fin number that tube connector connects progressively increases, and fully the heat exchange amount after the heat exchange can be very not big, and it is few that icing phenomenon appears in the heat exchanger tube surface, can have to guarantee the heat exchange effect.

(5) specific embodiment

See Fig. 1, Fig. 2, Fig. 3, the utility model comprises feed tube 1, fin heat exchange pipe, escape pipe 13, fin heat exchange pipe connects conducting by the different heat exchange pipeline section of number of fins by tube connector and forms, the heat exchange pipeline section is by fin number being disposed in order from less to more, be among Fig. 3, heat exchanger tube 2 with 4 fins, tube connector 3, the heat exchanger tube 4 that has 4 fins, tube connector 5, the heat exchanger tube 6 that has 8 fins, tube connector 7, heat exchanger tube 8 with 8 fins, tube connector 9, heat exchanger tube 10 with 12 fins, tube connector 11, with the conducting that is connected in series successively of the heat exchanger tube 12 of 12 fins, the heat exchanger tube 2 of 4 fins of feed tube 1 connecting band is with the heat exchanger tube 12 connection escape pipes 13 of 12 fins.The direction of arrow is the direction of cryogenic medium flows among Fig. 3.

Claims

1, ice-easy-removing air-bathing gasifier, it comprises feed tube, fin heat exchange pipe, escape pipe, it is characterized in that: described fin heat exchange pipe connects conducting by the different heat exchange pipeline section of number of fins by tube connector and forms, and described heat exchange pipeline section is by fin number being disposed in order from less to more.

2, according to the described ice-easy-removing air-bathing gasifier of claim 1, it is characterized in that: described fin heat exchange pipe by with the heat exchange pipeline section of 4 fins, with the heat exchange pipeline section of 8 fins, with between the heat exchange pipeline section of 12 fins by the tube connector conducting that is connected in series successively.
