Abstract
A kind of heat exchange gas device coil pipe, including the first tube body, the second tube body, third tube body is provided between first tube body and the second tube body, it is smooth inside and outside the third tube body, the first tube body inner ring is provided with the first internal tooth, and outer ring has been arranged alternately the first external tooth, and the second tube body inner ring is provided with the second internal tooth, outer ring has been arranged alternately the second external tooth, and external tooth is staggered certain angle in first tube body and the second tube body.The utility model uses the structure type of the first tube body, the second tube body, third tube body, corresponding liquified natural gas acutely gasifies in heat exchanger tube, coexist-the process of gaseous state instantaneous conversion from liquid-gas-liquid, when design takes into account gas flow, effectively prevents air-resistance phenomenon.
Description
Technical field
The utility model is related to metal heat treatment equipment technical field more particularly to a kind of heat exchange gas device coil pipes.
Background technology
In existing technology, natural gas is widely used as a kind of clean energy resource, but most area distance gas supply
Farther out, pipeline gas is difficult to reach to point, can natural gas be pressed gas-liquid volume ratio 625 in the air source place of production：1 carries out cooling liquid into liquid
Natural gas-LNG is transported to using low-temperature tanker with gas point, is gasified using gasifier and enters rear gas after depressurizing plus being smelly
Pipe network, suitable for industry and civilian users, liquified natural gas gasifier is generally the gasification of air temperature type form, energy saving, but ring
Border temperature does not work less than 0 DEG C of air-heating type gasifier, this just needs the heat exchanger coils using forced heat-exchanging.
Invention content
The utility model is redesigned by the structure type of heat exchanging device coil pipe, proposes that a kind of heat exchange efficiency is high, can be with
Proof strength and the heat exchange gas device coil pipe for preventing deformation, substantially prolong service life.
The utility model is realized in this way：A kind of heat exchange gas device coil pipe, including the first tube body, the second tube body,
It is characterized in that：It is provided with third tube body between first tube body and the second tube body, smooth, institute inside and outside the third tube body
The the first tube body inner ring stated is provided with the first internal tooth, and outer ring has been arranged alternately the first external tooth, and the second tube body inner ring is provided with
Second internal tooth, outer ring have been arranged alternately the second external tooth, and external tooth is staggered certain angle in first tube body and the second tube body.
As preferred technical solution, first internal tooth has 36, and second internal tooth has 36, in described first
Tooth and the second internal tooth are staggered 5 °.
The beneficial effects of the utility model：
1st, the utility model is made of alloy material, and under nearly 250 DEG C of the cold and hot medium temperature difference, expand with heat and contract with cold width
Small, Low temperature-resistancorrosion-resistant corrosion-resistant requirement is spent, deflection is small.
2nd, the utility model uses the structure type of the first tube body, the second tube body, third tube body, and corresponding liquified natural gas exists
Acutely to gasify in heat exchanger tube, coexist-the process of gaseous state instantaneous conversion from liquid-gas-liquid, when design, takes into account gas flow,
Effectively prevent air-resistance phenomenon.

Fig. 2 is the A-A sectional views of Fig. 1；
Fig. 3 is the B-B sectional views of Fig. 1；
Fig. 4 is the C-C sectional views of Fig. 1；
In figure:1st, the first tube body；11st, the first internal tooth；12nd, the first external tooth；2nd, the second tube body；21st, the second internal tooth；22nd,
Two external tooths；3rd, third tube body.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Reference attached drawing, a kind of heat exchange gas device coil pipe, including the first tube body 1, the second tube body 2, first tube body 1
It is provided with third tube body 3 between the second tube body 2, smooth inside and outside the third tube body 3,1 inner ring of the first tube body is set
The first internal tooth 11 is equipped with, outer ring has been arranged alternately the first external tooth 12, and 2 inner ring of the second tube body is provided with the second internal tooth 21, outside
Circle has been arranged alternately the second external tooth 22, and external tooth is staggered certain angle in 1 and second tube body 2 of the first tube body.
As preferred technical solution, first internal tooth 11 has 36, and second internal tooth 21 has 36, and described
One internal tooth and the second internal tooth are staggered 5 °.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model, and the available prior art of each component part being not known in the present embodiment adds
To realize.
