Abstract
The present invention discloses an arrangement method for heat transfer pipes in heat exchangers. A plurality of heat transfer pipes are arranged in a heat exchanger, and the heat transfer pipes are copper pipes or steel pipes. The arrangement method has the steps: all the heat transfer pipes are divided into four clusters; the number of the first cluster of pipes is equal to that of the fourth cluster of pipes; the number of the second cluster of pipes is equal to that of the third cluster of pipes; the number of the second cluster of pipes or the number of the third cluster of pipes is approximately equal to a half of that of the first cluster of pipes or the fourth cluster of pipes, and the distance among the clusters of pipes is adjusted so as to be equal to a diameter of the heat transfer pipes plus 5mm to 6mm. The arrangement method is suitable for shell-and-pipe heat exchangers, the arrangement method for heat transfer pipes can be used in the heat exchangers so as to attain good heat transfer effects, and the heat exchangers with different water inlet and outlet temperature difference can be conveniently combined.
Description
Technical field
The present invention relates to a kind of shell-and-tube heat exchanger, relate in particular to the aligning method of heat-transfer pipe in the shell-and-tube heat exchanger.
Background technology
Shell-and-tube heat exchanger is a kind of traditional, most widely used heat-exchange apparatus, because it is firm in structure, and can select multiple material manufacturing for use, so adaptability is extremely strong, especially is widely used in high temperature, high pressure and large-scale plant.Shell-and-tube heat exchanger mainly is made of three big built-up sections: front end bobbin carriage (comprising demarcation strip, adapter, adpting flange etc.), middle casing (comprising housing, shell-and-tube heat exchanger and connecting pipe of shell, flange etc.), rear end bobbin carriage (similar with the front end bobbin carriage).
In the shell-and-tube heat exchanger of middle casing, have a plurality ofly by the heat-transfer pipe that shell wrapped up, the two ends of these heat-transfer pipes are fixed on the tube sheet.At present, the arrangement mode of heat-transfer pipe has square arrangement, rounded projections arranged, and multiple mode such as diamond array, but heat-transfer effect is not ideal, and can't satisfy different water-in and water-out temperature difference requirements.
Summary of the invention
In order to overcome deficiency of the prior art, technical problem to be solved by this invention provides the aligning method of heat-transfer pipe in a kind of shell-and-tube heat exchanger, make heat exchanger reach best heat-transfer effect, and can be combined into the heat exchanger of the different water-in and water-out temperature difference easily.Now be summarized as follows:
The aligning method of heat-transfer pipe in the shell-and-tube heat exchanger of the present invention is provided with a plurality of heat-transfer pipes in shell-and-tube heat exchanger, described heat-transfer pipe is copper pipe or steel pipe.The steps include:
(1) all heat-transfer pipes is divided into four bunches;
(2) make first bunch of pipe number equate with the 4th bunch of pipe number;
(3) make second bunch of pipe number equate with the 3rd bunch of pipe number;
(4) make second bunch of pipe number or the 3rd bunch of half of managing number and approximating first bunch of pipe number or the 4th bunch of pipe number;
(5) spacing of every bunch of pipe of adjustment makes it equal the heat-transfer pipe diameter and adds 5mm～6mm.
The aligning method of heat-transfer pipe compared with prior art has following beneficial effect in the heat exchange dress Chinese alligator of the present invention:
1. adopt the aligning method of heat-transfer pipe in the shell-and-tube heat exchanger of the present invention, heat exchanger can reach heat-transfer effect preferably;
2. adopt the present invention can be combined into the heat exchanger of the different water-in and water-out temperature difference easily.

The concrete real mode of revolving
Below in conjunction with the drawings and specific embodiments the aligning method of heat-transfer pipe in the shell-and-tube heat exchanger of the present invention is done into～goes on foot to describe in detail:
The aligning method of heat-transfer pipe in a kind of shell-and-tube heat exchanger is provided with a plurality of heat-transfer pipes in shell-and-tube heat exchanger, described heat-transfer pipe is copper pipe or steel pipe.The steps include:
(1) all heat-transfer pipes is divided into four bunches;
(2) make first bunch of pipe number (being made as n1) equate, i.e. n1=n4 with the 4th bunch of pipe number (being made as n4);
(3) make second bunch of pipe number (being made as n2) equate, i.e. n2=n3 with the 3rd bunch of pipe number (being made as n3):
(4) make second bunch of pipe number or the 3rd bunch pipe number equal about half of the～bunch pipe number or the 4th bunch of pipe number,
Be n2=n3=(50% ± 2%) nl=(50% ± 2%) n4;
(5) spacing (being made as L) of whole every bunch of pipe makes it equal heat-transfer pipe diameter (being made as Φ) and adds 5mm～6mm,
Be L=Φ+(5～6) mm.
Rising respectively and be connected on the tube sheet in described heat-transfer pipe two ends, can adopt copper pipe, as fine copper (T2) copper pipe, phosphorous (TP2) copper pipe, also can adopt various steel pipes.
The aligning method of heat-transfer pipe in the shell-and-tube heat exchanger of the present invention, can be used for heat exchange between vapour～liquid, liquid～liquid, and can be according to the heat exchange requirement, with a plurality of shell-and-tube heat exchanger serial or parallel connection combinations, the leaving water temperature scope that can reach is 40 ℃～90 ℃ flexibly.
The aligning method of heat-transfer pipe can be applied to heat-exchange apparatus and firing equipment in a kind of shell-and-tube heat exchanger of the present invention and the shell-and-tube heat exchanger.
More than be schematically to the description of the present invention and embodiment thereof, do not have restricted.So, if those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the invention aim, make other embodiment, all should belong to protection scope of the present invention.
