Description

A closed cooling tower with high efficiency

Technical Field

The utility model relates to the field of cooling tower devices, in particular to a closed cooling tower with high efficiency in cooling.

Background Art

A closed cooling tower places a tubular heat exchanger inside the tower. The cooling effect is ensured by the heat exchange between the circulating air, the spray water outside the tube and the circulating water inside the tube. When the outside temperature is low, the spray water system can be stopped to save water. Although the water has achieved a closed internal circulation, its basic heat dissipation uses gas heat dissipation. The gas enters from the outside and contains more dust and impurities when entering the tower body. If a dust filter is added, the mesh holes will quickly be blocked, affecting the air intake efficiency. If dust is allowed to enter the tower body, especially during spraying, the water in the water tank will inevitably be contaminated and need to be cleaned and replaced, affecting efficiency.

The utility model achieves the above-mentioned purpose through the following technical solutions:

A closed cooling tower with high efficiency cooling comprises a water tank and a tower body, the tower body is provided with a plurality of air inlet holes, the water tank is installed at the bottom of the tower body, a dirt guide hopper is installed at the bottom of the water tank, a slag discharge cylinder is installed at the dirt discharge port of the dirt guide hopper, a partition is installed on the inner box wall of the water tank, a water guide baffle is installed between the top of the partition and the inner wall of the water tank, an inclined pipe group is provided below the partition, a filter layer is installed on the top of the inclined pipe group, a circulating pump is installed on the outside of the water tank, a pump inlet pipe and a drain pipe are respectively installed on the pump inlet and outlet of the circulating pump, the end of the drain pipe extends to the interior of the tower body and is provided with a spray head, one end of the pump inlet pipe is connected to the water tank, a discharge hole is provided on the top of the tower body, and an air induction component is installed above the discharge hole.

In the above scheme, wind enters from the air inlet, and part of the dust in the wind is discharged through the induced draft assembly, and the other dust is washed off by the spray head and flows down through the water guide baffle. The falling water flows along the water guide baffle to one side of the partition, and enters the inclined tube group below the water guide baffle through the bottom of the partition. A filter layer is installed on the top of the inclined tube group. Since impurities and dust are inevitably introduced with the air, they are precipitated through the inclined tube sedimentation principle and discharged through the slag discharge barrel. A circulating pump is installed on the outside of the water tank, and a pump inlet pipe and a drain pipe are installed on the pump inlet and the pump outlet respectively. The water above the filter layer is introduced into the pump inlet pipe through the pump inlet of the circulating pump, and then reaches the drain pipe. The end of the drain pipe extends to the spray head inside the tower body to spray water again, thereby realizing the filtration and precipitation of water impurities in the water tank and slag discharge, performing uninterrupted cooling operations and keeping the water clean, thereby improving the cooling efficiency.

Furthermore, an auger shaft is rotatably installed inside the slag discharge barrel, an auger is installed on the auger shaft, a debris discharge motor is installed on the top of the slag discharge barrel, and the top end of the auger shaft is connected to the debris discharge motor.

In the above scheme, the combination of the auger shaft and the auger can automatically collect and discharge impurities and waste deposited in the slag discharge barrel without manual operation. The driving action of the impurity discharge motor triggers the rotation of the auger, thereby pushing the impurities to the top of the slag discharge barrel, realizing the function of automatic slag discharge.

Furthermore, a coil is installed in the tower body, and a refrigerant is arranged in the coil.

In the above scheme, the cooling effect of the cooling tower can be improved by installing a coil in the tower body and injecting a refrigerant. The refrigerant circulates in the coil and exchanges heat with the air outside the tower body, thereby reducing the temperature inside the tower body.

Furthermore, a water-blocking layer is installed in the tower body.

In the above scheme, the water blocking layer is arranged above the sprinkler head. When the sprinkler head sprays water, splashing may occur sometimes, causing water to splash everywhere. By arranging the water blocking layer above the sprinkler head, water splashing during the spraying process can be effectively reduced, preventing the water from spreading to areas that do not require cooling.

Furthermore, a bracket is installed on the bottom support of the dirt guide hopper.

In the above scheme, the bottom of the sewage hopper can be maintained and cleaned more easily by installing the bracket. The lifting effect of the bracket can keep the bottom of the sewage hopper at a certain distance from the ground, which is convenient for operators to clean, maintain and overhaul, and improve work efficiency and safety.

The utility model has the beneficial effect of realizing the filtration, precipitation and slag discharge of water impurities in the water tank, performing cooling operation uninterruptedly and keeping the water clean, thereby improving the cooling efficiency. Wind enters from the air inlet, wherein part of the dust in the wind is discharged through the air induction assembly, and the other dust is washed off by the spray head and flows down through the water guide baffle, and the falling water flows along the water guide baffle to one side of the partition, and enters the inclined tube group below the water guide baffle through the bottom of the partition, and a filter layer is installed on the top of the inclined tube group. Due to the inevitable introduction of impurities and dust with the air, they are precipitated through the inclined tube precipitation principle and discharged through the slag discharge cylinder, a circulating pump is installed on the outside of the water tank, and a pump inlet pipe and a drain pipe are installed on the pump inlet and the pump outlet respectively, and the water above the filter layer is introduced into the pump inlet pipe through the pump inlet of the circulating pump, and then reaches the drain pipe, and the end of the drain pipe extends to the spray head inside the tower body to spray water out.

DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings:

As shown in FIG1 , a closed cooling tower with high efficiency in cooling is composed of a water tank 1 and a tower body 2;

The water tank 1 is a coverless water tank, which is convenient for water reflux. The water tank 1 is installed at the bottom of the tower body 2. A sewage guide hopper 8 is installed at the bottom of the water tank 1. A slag discharge cylinder 7 is installed at the sewage outlet of the sewage guide hopper 8, which is mainly used to discharge impurities and dust entering the air inlet 12 to avoid frequent water changes.

A partition 4 is installed on the inner wall of the water tank 1, and a water guide baffle 3 is installed between the top of the partition 4 and the inner wall of the water tank 1. The falling water flows along the water guide baffle 3 to one side of the partition 4, and enters the inclined tube group 5 below the water guide baffle 3 through the bottom of the partition 4. A filter layer 6 is installed on the top of the inclined tube group 5. Since impurities and dust are inevitably introduced with the air, they are precipitated according to the inclined tube sedimentation principle and discharged through the slag discharge tube 7.

A circulation pump 11 is installed on the outside of the water tank 1, and a pump inlet pipe 10 and a drain pipe 13 are installed on the inlet and outlet of the circulation pump 11. The end of the drain pipe 13 extends to the inside of the tower body 2 and is installed with a spray head 19. One end of the pump inlet pipe 10 is connected to the water tank 1 to circulate and drain the water above the filter layer 6;

The top of the tower body 1 is provided with rows of holes, and an induced draft driving member 16 is installed above the rows of holes through a motor frame 17 , and an induced draft fan blade 15 is connected and installed on the induced draft driving member 16 .

As shown in FIG1 , the present invention also discloses the following more optimized specific structures:

An auger shaft 22 is rotatably installed inside the slag discharge barrel 7, and the auger 18 is installed on the auger shaft 22. A debris discharge motor 21 is installed on the top of the slag discharge barrel 7. The top of the auger shaft 22 is connected to the debris discharge motor 21 to drive the auger shaft 22. A slag discharge hole is provided on the top of the side of the slag discharge barrel 7.

In the above embodiment, the combination of the auger shaft 22 and the auger 18 can automatically collect and discharge the impurities and wastes deposited in the slag discharge barrel 7 without manual operation. The driving action of the impurity discharge motor 21 causes the auger 18 to rotate, thereby pushing the impurities to move to the top of the slag discharge barrel 7, realizing the automatic slag discharge function. This helps to maintain the normal operation and safety of the cooling tower and improve its working efficiency and service life.

A coil 20 is installed in the tower body 2, and a plurality of air inlet holes 12 are provided on the tower body 2 below the coil 20. The cooling effect of the cooling tower can be improved by installing the coil 20 in the tower body 2 and injecting refrigerant. The refrigerant circulates in the coil 20 and exchanges heat with the air outside the tower body 2, thereby reducing the temperature inside the tower body 2.

A water-blocking layer 14 is installed in the tower body 2, which is mainly used to reduce water splashing. The water-blocking layer 14 is arranged above the spray head 19. When the spray head 19 sprays water, splashing may sometimes occur, resulting in water splashing. By arranging the water-blocking layer 14 above the spray head, water splashing during the spraying process can be effectively reduced to prevent the water splash from spreading to areas that do not require cooling.

The bottom support of the dirt guide hopper 8 is installed with a bracket 9. By installing the bracket 9, the bottom of the dirt guide hopper 8 can be maintained and cleaned more easily. The lifting effect of the bracket 9 can keep the bottom of the dirt guide hopper 8 at a certain distance from the ground, which is convenient for operators to clean, maintain and overhaul, and improve work efficiency and safety.

During the use of the closed cooling tower with high efficiency cooling described in the above structure, wind enters from the air inlet 12 to cool the refrigerant in the coil 20, wherein part of the dust in the wind is discharged, and the rest of the dust is washed off by the spray head 19 and flows down through the water guide baffle 3, and the water flows in from the bottom of the inclined tube group 5 to achieve sedimentation, and the clean water continues to circulate through the filter layer 6 and the circulating pump 11;

The accumulated dust and impurities are introduced into the slag discharge tube 7 through the dirt guide hopper 8 and discharged under the drive of the auger 18. The whole process does not require stopping the machine to clean up the debris and change the water, thereby improving the cooling efficiency.

Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
