Background

Taking the refrigeration station as an example, the heat generated by the refrigerator is carried to the cooling tower by the circulating cooling water, the heat is discharged through the cooling tower, the water temperature is reduced to the required temperature, the water enters the refrigerator again to carry the heat away, and the operation is repeated. The closed cooling tower is used, so that water in the system can not be contacted with the atmosphere, and the closed cooling tower has the advantages that suspended matters and dissolved oxygen in circulating water can not be increased, and no organisms such as moss are bred, so that the closed cooling tower has great benefits on the corrosion resistance of a pipeline and the heat exchange efficiency of equipment.

In closed cooling towers, the coil is the most critical core component. Outstanding coil pipe scheme not only can reduce the running cost, increase of service life, can also be convenient for maintenance.

The coil pipes used by the existing closed cooling tower are mostly integral coil pipes, and the closed cooling tower has the advantages that no joint exists in the coil pipes, and the defects that once a leakage point exists, the whole coil pipe is scrapped, the cost is high, and the replacement period is long; in addition, the assembled coil pipe has the advantages of convenient maintenance and high cost and hidden water leakage danger due to too many internal joints.

SUMMERY OF THE UTILITY MODEL

The present invention aims to overcome the technical drawbacks of the prior art by providing a disc-shaped coil for a closed cooling tower.

The technical scheme adopted for realizing the purpose of the utility model is as follows:

a disc-shaped coil pipe for a closed cooling tower is formed by arranging a plurality of disc-shaped disc modules in an overlapped mode from top to bottom, each disc module is formed by continuously bending and coiling at least one pipe body for a plurality of circles, and two ends of each pipe body are connected with corresponding circulating water main pipes through connectors.

Preferably, the main circulating water pipe is arranged on the outer wall of the closed cooling tower.

Preferably, the circulating water main pipe is connected with an external water pipe through a flange interface or a screw thread interface.

Preferably, when each disk module is formed of two or more tubes, the coil structure of each tube has the same shape and the corresponding coil radius of each coil is different.

The disc-shaped coil pipe for the closed cooling tower is characterized in that each disc-shaped pipe is formed by bending a formed pipe body, and the disc-shaped pipe is free of joints and does not need to be connected by an elbow, so that the reliability is improved; the special elbow production is not needed, and the cost is reduced; the maintenance is simple, the material requirement to the tool requirement are greatly simplified, the maintenance technical requirement is greatly reduced, and the maintenance speed is greatly accelerated; and the structure can still basically run normally under the condition that a certain coil pipe sheet is damaged, and the cooling tower can work without maintenance even when a certain part of the coil pipe is damaged and can be maintained when the cooling tower is stopped, so that the reliability of the cooling tower can be improved.

Detailed Description

The utility model is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1 to 6, a disc-shaped coil pipe for a closed cooling tower according to an embodiment of the present invention is formed by stacking a plurality of disc-shaped disc modules 1 up and down, each disc module 1 is formed by continuously bending and winding at least one pipe body 2 for a plurality of turns, and both ends of each pipe body are connected to corresponding circulating water main pipes 3 through joints 4.

Wherein, the coil-formed structure is arranged in the tower body and can be connected and fixed with the frame member in the tower body

As an optional embodiment, the main circulating water pipe is disposed on an outer wall of the closed cooling tower, and specifically, the main circulating water pipe may be connected to a tower enclosure of the closed cooling tower.

As an alternative embodiment, the main circulating water pipe can be connected with an external water pipe by adopting a flange interface or a screw thread interface.

And nominal diameter specifications of the coil pipe and the circulating water main pipe are determined according to specific flow calculation.

According to the technical idea of the utility model, the coil pipe structure can be divided into a single pipe basic type, a double pipe basic type and a three pipe basic type according to the number of each pipe; single tube basic types, i.e., each formed by one tube coil, and double tube basic types, i.e., each formed by two tube coils, as shown in fig. 3; the three-tube basic model, i.e. each formed by three coils, is shown in fig. 4.

When each disk module is formed by two or more metal pipe bodies, the coil structure of each pipe body is the same in shape, and the corresponding coil radius of each coil is different, so that the pipe body on the outer side can surround or shield the pipe body on the inner side on the outer side, a plurality of pipe bodies are basically coiled together in the same plane according to the same shape, and then the inner end connected with the circulating water main pipe is pulled out of the disk die from the surface of the formed disk model so as to facilitate the connection of the outer end and the circulating water main pipe together, of course, a plurality of corresponding connecting pipe orifices are formed on the circulating water main pipe.

The tube body is a metal tube, such as a copper tube.

The coil structures formed by the single-tube basic type, the double-tube basic type and the three-tube basic type can be used independently, or can be used in a combined mode respectively or combined mutually, and when the coil structures are used in a combined mode, two groups of coils can be combined, or three groups of coils can be combined, or four groups of coils can be combined, as shown in figures 5-6.

The coil pipe can be produced in a modularized way, and the coil pipe can be formed by cold bending or hot bending; the coil can be used for small and medium circular counter-flow cooling towers and small and medium square counter-flow cooling towers.

According to the disc-shaped coil pipe for the closed cooling tower, the coil pipe is arranged in a modularized manner, the coil pipe is not provided with a smaller bending radius due to brand-new arrangement of the coil pipe, and the minimum radius is controlled within the range capable of being formed by cold bending, so that the coil pipe can be formed by simple cold bending or hot bending without a specially-produced elbow, and the problems of high maintenance cost, long replacement period, large water leakage hidden danger and the like of the existing closed cooling tower coil pipe are solved.
