New water collection structure for cooling tower

Abstract

A new water collecting structure for a cooling tower relates to the technical field of cooling tower equipment, including a cooling tower, wherein a plurality of vertically arranged shielding parts are fixedly connected in parallel in the cooling tower, and an alternating cold channel and a hot channel are formed through the area between adjacent shielding parts, and a demisting module is supported on the top of each shielding part, and a cold channel water retaining platform and a hot channel water retaining platform are fixedly connected to the upper end of the shielding part corresponding to the cold channel and the hot channel respectively, and the height of the cold channel water retaining platform is higher than that of the hot channel water retaining platform, and a dewatering pipe for dewatering condensed water is also connected to the water collecting trough. The utility model solves the problem that during the operation of the demisting cooling tower in the traditional technology, the condensed water in the demisting module flows along the module to the module layer beam, and finally flows into the hot channel, and finally flows into the water pool through the hot channel. Since the condensed water has fewer impurities than the water in the water pool, it directly flows into the water pool, causing a waste of water resources.

Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower appliances, in particular to a novel water collecting structure of a cooling tower. Background Art

[0002] The most mature application of defogging and water-saving cooling tower technology is the modular defogging and water-saving cooling tower. The principle is based on wall-type heat exchange, and the defogging and water-saving effects are very good. Principle: Based on the basic theory of condensation heat exchange, heat conduction and convection heat and mass transfer, the water vapor after evaporation and heat exchange of the circulating water in the cooling tower is deeply condensed into a film through convection and heat conduction, and then collected and reused repeatedly, which effectively improves the utilization rate of circulating water and effectively reduces the generation of visible water mist in the cooling tower. When the cooling tower is defogging and collecting water, its water source recovery effect is poor, and it is difficult to effectively collect the condensed water source.

[0003] A patent CN105277008A is disclosed in the prior art. The solution includes a cooling tower body, wherein a damper for inhaling condensed air is arranged on the side wall of the cooling tower body, a wind tube connected to the cooling tower body is connected to the top surface of the cooling tower body, and a cyclone separator is arranged in the wind tube. The damper is arranged on the side wall of the cooling tower body, and the air introduced in the damper can further cool the water vapor inside the cooling tower body to form saturated water vapor, which condenses into small water droplets. When the small water droplets pass through the cyclone separator in the wind tube, they are recovered and can be recycled, which saves water resources and improves the cooling capacity of the cooling tower.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] During the operation of a traditional mist-eliminating cooling tower, the condensed water in the mist-eliminating module flows along the module to the module layer beam, and finally flows into the hot channel, and finally flows into the water pool through the hot channel. Since the condensed water has fewer impurities than the water in the water pool, it flows directly into the water pool, causing a waste of water resources.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] In view of the defects in the prior art, the utility model provides a new water collection structure for a cooling tower to solve the problem that during the operation of the demisting cooling tower in the traditional technology, the condensed water in the demisting module flows along the module to the module layer beam, and finally flows into the hot channel, and finally flows into the water pool through the hot channel. Since the condensed water has less impurities than the water in the water pool, it flows directly into the water pool, causing water resource waste.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A novel water collecting structure for a cooling tower includes a cooling tower, wherein a plurality of vertically arranged shielding parts are fixedly connected in parallel in the cooling tower, and an alternating cold channel and a hot channel are formed through the area between adjacent shielding parts, and a defogging module is supported on the top of each shielding part.

[0010] The upper end of the shielding portion corresponds to the cold channel and the hot channel, respectively, and is fixedly connected to a cold channel water retaining platform and a hot channel water retaining platform. The upper end of the shielding portion forms a water collecting trough through the area between the cold channel water retaining platform and the hot channel water retaining platform. The height of the cold channel water retaining platform is higher than that of the hot channel water retaining platform, and the upper end of the hot channel water retaining platform forms an overflow platform.

[0011] The water collecting tank is also connected with a discharge pipe for discharging condensed water.

[0012] As an optimized solution, the cold channel water retaining platform and the hot channel water retaining platform are both L-shaped and arranged opposite to each other.

[0013] As an optimized solution, the transverse plate section of the cold channel water retaining platform is fixedly connected to the upper end of the shielding portion.

[0014] As an optimized solution, the transverse plate section of the hot channel water retaining platform is fixedly connected to the side wall of the shielding portion in the hot channel.

[0015] As an optimized solution, the upper surface of the transverse plate section of the hot channel water retaining platform is flush with the upper surface of the shielding portion.

[0016] As an optimized solution, the outlet pipe includes a branch pipe, which is fixed to the transverse plate section of the hot channel water retaining platform and is connected to the water collecting tank.

[0017] As an optimized solution, each branch pipe is connected to an electric valve.

[0018] As an optimized solution, the lower ends of a plurality of branch pipes are commonly connected to a horizontally arranged main pipe, and a drainage pipe extending downward is connected to the main pipe.

[0019] As an optimized solution, the shielding portion includes a top beam fixedly connected between opposite inner walls of the cooling tower, and a baffle is fixedly connected to the lower end of the top beam.

[0020] As an optimized solution, a pipe rack for supporting the branch pipes and the main pipe is fixedly connected to the baffle.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The novel arrangement form is to increase a hot channel water retaining platform so that the height of the hot channel water retaining platform is lower than that of the cold channel water retaining platform. A branch pipe is arranged in the hot channel water retaining platform. When condensed water needs to be collected, the condensed water is allowed to flow out from the pre-buried pipe; if collection is not required, the electric valve is closed to allow the condensed water to flow over the overflow platform and flow into the hot channel, thereby realizing the reuse of the condensed water of the demisting module and saving water resources.
