Abstract
The utility model discloses a kind of snakelike tube body high-performance heat exchangers of CNG.Including outer housing and it is arranged in the intracorporal snakelike tube body of the shell, the outer housing both ends are respectively arranged with inlet and outlet, and the snakelike tube body both ends are respectively arranged with air inlet and air outlet.The utility model is compact-sized, and heat transfer area is big, and heat transfer coefficient is big, and metal wastage is small, not only economical but also reasonable.
Description
Technical field
The utility model relates to gas-fired equipment technical field, especially a kind of snakelike tube body high-performance heat exchanger of CNG.
Background technique
Compressed natural gas (Compressed Natural Gas, abbreviation CNG) finger pressure is reduced to pressure more than or equal to 10MPa
And it is not more than the gaseous natural gas of 25MPa, is natural gas pressurization and is stored in a reservoir with gaseous state.
CNG is a kind of optimal automobile-used alternative energy source, and application technology has reached its maturity through many decades development.It has
At low cost, high efficiency is pollution-free, the features such as using safe and convenient, just increasingly shows powerful development potentiality.
A large amount of thermal energy of ambient enviroment are absorbed in decompression process in CNG, if supplementing these thermal energy not in time will go out
Existing pipeline frosting is even freezed, and pipeline and its attached pipe fitting valve is greatly destroyed, so to increase on decompression unit a set of
Heating device.
Heat exchanger haves the shortcomings that common is that structure is not compact at present, heat transfer area provided by the volume of unit heat exchanger
Small, heat transfer coefficient is little, and metal wastage is big.
Utility model content
The utility model aiming at the shortcomings in the prior art, provides a kind of snakelike tube body high-performance heat exchanger of CNG, and structure is tight
It gathers, heat transfer area is big, and heat transfer coefficient is big, and metal wastage is small, not only economical but also reasonable.
In order to solve the above technical problems, the utility model is addressed by following technical proposals: a kind of snakelike tube body of CNG
High-performance heat exchanger, including outer housing and setting, in the intracorporal snakelike tube body of the shell, the outer housing both ends are respectively arranged with
Inlet and outlet, the snakelike tube body both ends are respectively arranged with air inlet and air outlet.
In above scheme, it is preferred that the snakelike tube body is rearranged by three layers of coiled pipe, diameter be respectively 450mm,
375mm and 300mm.
In above scheme, it is preferred that it is additionally provided with water pipe in the outer housing, described water pipe one end intakes one end water outlet,
Meanwhile the pipe outer wall abuts against the smallest coiled pipe of diameter in the snakelike tube body.
The beneficial effects of the utility model are: the utility model is compact-sized, heat transfer area is big, and heat transfer coefficient is big, metal
Consumption is small, not only economical but also reasonable.
Detailed description of the invention
Fig. 1 is utility model diagram.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing: a kind of referring to Fig. 1
The snakelike tube body high-performance heat exchanger of CNG, including outer housing 1 and the snakelike tube body 2 being arranged in the outer housing 1, the outer housing 1
Both ends are respectively arranged with water inlet 11 and water outlet 12, and snakelike 2 both ends of tube body are respectively arranged with air inlet 21 and gas outlet
22。
The snakelike tube body is rearranged by three layers of coiled pipe, and diameter is respectively 450mm, 375mm and 300mm.
It is additionally provided with water pipe 3 in the outer housing 1, described water pipe one end intakes one end water outlet, meanwhile, the pipe outer wall
Abut against the smallest coiled pipe of diameter in the snakelike tube body.
The two kinds of fluids to exchange heat in heat exchanger, one kind flow in pipe, and stroke is known as tube side；One kind is outside pipe
Flowing, stroke are known as shell side.Tube side is heat exchanger tube, meets GB13296-2013 " boiler, heat exchanger stainless steel jointless steel
Pipe " standard, material S30408, using 3 layers of coiled pipes arrangement, diameter is respectively 450mm, 375mm, 300mm, tube side CNG gas
Body is by snakelike tube body air inlet into gas outlet goes out.Shell side is circulating hot water, and inflow temperature is 85 DEG C, and leaving water temperature is 60 DEG C, by
Water inlet is into water outlet goes out, because the temperature of hot water is high, the temperature of natural gas is low, and the temperature tradition of hot water makes into natural gas
The temperature for obtaining export gas increases, and when CNG gas is after the pressure regulation of downstream, pressure reduces, and temperature is substantially reduced, can be damaged down
Equipment is swum, so giving CNG gas heating in advance, the utility model takes full advantage of space advantage, increases heat exchange area, thus
Heat exchange efficiency is provided.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
It modifies or replaces, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
