Abstract
A few-flow-path heat exchanger mainly relates to an industrial centrifugal compressor middle cooler, cooling water source water quality is poor and scale is easy to form. A front cover plate (5) adopts two-flow-path design, and one cooling pipe (5-1) is installed on a surface of the front cover plate (5). Due to the structure, the flow paths of cooling water in a cooling water pipe are shortened, temperature rise is reduced under the same condition, a condition of high cooling water temperature of a large-flow-path cooler is effectively avoided, a direct result of reduced temperature rise is that the scale is reduced, a compressor tripping phenomenon is avoided, and service maintenance cost is reduced. The few-flow-path heat exchanger provides guarantee for continuing long-time operation of the cooler without tripping and factory production, compared with the large-flow-path cooler, the two-flow-path cooler is practical in manufacture, production cost is greatly reduced, and the few-flow-path heat exchanger is suitable for popularization.
Description
Technical field：
The invention mainly relates to be for industrial cooling water source water quality to be poor, easy fouling centrifugal compressor intercooler, and in particular to be a kind of improvement of few flow heat exchanger.
Background technology：
Progress and industrial expansion with society, centrifugal compressor are increasingly being applied to the national pillar industry such as steel, oil, weaving at home.Vast in territory, the abundant water of China, but it is poor or inflow temperature is very high in some regional water qualities.Original cooler temperature rise is higher, in the case where water quality is poor, and the impurity in cooling water is separated out, and can be internally formed incrustation scale in cooling tube, blockage can will be cooled down when serious.In this case, cooling effect drastically declines, and compressed gas temperature can be caused to raise, control system can automatic chaser protect compressor.Client would have to shutdown inspection, and attendant needs to scene to carry out maintenance of clean-up.Compressor shutdown can be caused to have a strong impact on to the operation of large enterprise, and the service fee of compressor enterprise can also be improved.
The intercooler of original centrifugal compressor generally uses the design of 4 flows or 6 flows, and such design requirement cooling water walks 4 or 6 back and forth in cooling water pipe, fully to be contacted with thermal source, takes away the heat of thermal source, so as to reach the purpose of cooling.Such design can make cooling water temperature rise higher, temperature rise, and impurity solubility in water is reduced, so that easily structure, influence radiating.
The content of the invention：
It is an object of the invention to provide a kind of few flow heat exchanger, it not only can need not propose rigors to the cooling water source of client, can also reduce the frequency of compressor shutdown maintenance, reduce the expense of compressor user and manufacturer.
In order to solve the problems existing in background technology, the present invention uses following technical scheme：It includes core group 1, back tube sheet 2, front tube sheet 3, back shroud 4 and front shroud 5；Core group 1 is respectively arranged at two ends with back tube sheet 2 and front tube sheet 3, and back shroud 4 covers the rear side in back tube sheet 2, front shroud 5 covers the front side in front tube sheet 3, and described front shroud 5 uses 2 flow scheme designs, and a cooling tube 5-1 is arranged on the surface of front shroud 5.
The invention has the advantages that：Because the flow that the structures shape cooling water of the present invention is walked in cooling water pipe shortens, temperature rise reduction under the same conditions, effectively overcome the higher situation of the coolant water temperature of big flow cooler, and the direct result of temperature rise reduction is exactly fouling reduction, the chaser phenomenon of compressor is reduced, the reduction of services and repairs cost；For cooler, not chaser operation and the lasting progress of plant produced provide guarantee, and relative to the cooler of big flow, the cooler of two flows is more feasible in manufacture, and production cost greatly reduces for a long time, suitable to promote.

Embodiment：
Referring to Fig. 4-5, present embodiment is to use following technical scheme：It includes core group 1, back tube sheet 2, front tube sheet 3, back shroud 4 and front shroud 5；Core group 1 is respectively arranged at two ends with back tube sheet 2 and front tube sheet 3, and back shroud 4 covers the rear side in back tube sheet 2, front shroud 5 covers the front side in front tube sheet 3, and described front shroud 5 uses 2 flow scheme designs, and a cooling tube 5-1 is arranged on the surface of front shroud 5.
It is specifically that embodiment only requires that cooling water walks 2 flows in cooling tube 5-1 at this, so that temperature rise is reduced, reduces structure, reduction is safeguarded and the cost of overhaul.
This is specifically that embodiment has the advantages that：Due to having continued to use the identical design of cooler contour structures with original four flow and six flows, so the replacing of the cooler of four flows and six flows for original onsite application also extremely convenient；And specifically flow that the structures shape of embodiment cooling water is walked in cooling water pipe shortens, temperature rise reduction under the same conditions, effectively overcome the higher situation of the coolant water temperature of big flow cooler, and the direct result of temperature rise reduction is exactly fouling reduction, the chaser phenomenon of compressor is reduced, the reduction of services and repairs cost；For cooler, not chaser operation and the lasting progress of plant produced provide guarantee, and relative to the cooler of big flow, the cooler of two flows is more feasible in manufacture, and production cost greatly reduces for a long time, suitable to promote.
Drawings and Examples described herein are merely illustrative of the technical solution of the present invention rather than its limitations；Although having carried out relatively being described in detail to the present invention with reference to preferred embodiment, those of ordinary skill in the art should be understood；Still the embodiment of the present invention can be modified or equivalent is carried out to some technical characteristics；Without departing from the spirit of technical solution of the present invention, it all should cover among claimed technical scheme scope of the invention.
