Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower appliances, and particularly relates to a condensate recovery device. Background Art

[0002] The most mature technology application of the fog-eliminating and water-saving cooling tower is the modular fog-eliminating and water-saving cooling tower. The principle is based on the partition heat transfer, and the fog-eliminating and water-saving effects are very good. The principle: based on the basic theories of condensation heat transfer, heat conduction, and convective heat and mass transfer, the water vapor after the evaporation heat transfer of the circulating water in the cooling tower is deeply condensed into a film through convective and conductive heat transfer, and then collected for repeated circulation use, effectively improving the utilization rate of the circulating water. At the same time, the generation of visible water mist in the cooling tower is effectively reduced. When the cooling tower eliminates fog and collects water, the recovery water source effect is poor, and it is difficult to effectively collect the condensed water source.

[0003] A patent of CN212620236U is disclosed in the prior art. The solution includes an outer shell body. A second water collector is fixedly connected to the inner side of the outer shell body. A knocking device is fixedly connected to the inner side of the top end of the outer shell body. The knocking device is fixedly connected to the first water collector. The knocking device includes a first motor, a cam, a runner, a connecting rod, a knocking plate, a knocking block, a spring, a fixing frame, and a fixing rod. A first motor is fixedly connected to the inner side of the top end of the outer shell body. A cam is fixedly connected to the end of the main shaft of the first motor. In the utility model, through the setting of the first motor, the cam, the runner, the knocking plate, the knocking block, the spring, and the fixing frame, through the mutual collision between the knocking plate and the knocking block, the knocking plate generates periodic vibrations, and then the knocking plate transmits the vibrations to the first water collector, causing the first water collector to vibrate, and accelerating the rapid falling of the water droplets on the surface of the first water collector through the vibration of the first water collector.

[0004] With the use of the existing devices including the above patent, the deficiencies of this technology have gradually emerged, mainly manifested in the following aspects:

[0005] First, the condensed water formed in the fog-eliminating module of the existing fog-eliminating cooling tower contains particulate matter, which easily blocks the pipes and valves for discharging the condensed water, affecting the efficiency of discharging the condensed water.

[0006] Second, during the operation of the traditional fog-eliminating cooling tower, the condensed water in the fog-eliminating module flows along the module to the module layer beam, and finally flows into the hot channel, and finally flows into the water tank through the hot channel. Since the condensed water has fewer impurities than the water in the water tank, directly flowing into the water tank causes waste of water resources.

[0007] To sum up, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Utility Model

[0019] As an optimized solution, a flow meter and a valve are sequentially arranged on the drain pipe along the water outlet direction.

[0020] As an optimized solution, the support part includes a top beam fixedly connected between the opposite inner walls of the cooling tower, and a baffle is fixedly connected to the lower end of the top beam.

[0021] As an optimized solution, a pipe support for supporting the branch pipe and the main pipe is fixedly connected to the baffle.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] The new layout form is to increase the heat channel water baffle, make the height of the heat channel water baffle lower than that of the cold channel water baffle, and a branch pipe is arranged in the heat channel water baffle.

The upper end of the support part 3 forms a water collecting tank through the area between the cold channel water retaining platform 11 and the hot channel water retaining platform 12. The hot channel water retaining platform 12 is connected with a lead-out pipe for leading out the condensate.

[0031] An inclined filter plate 13 covering the inlet end of the lead-out pipe is fixedly connected in the water collecting tank. The lower end of the filter plate 13 is fixedly connected with the support part 3, and the upper end of the filter plate 13 is flush with the top of the hot channel water retaining platform 12. A scraper 14 that is in frictional contact with the upper surface of the filter plate 13 is slidably arranged on the filter plate 13 from bottom to top.

[0032] Screws 16 are rotatably arranged in parallel above the filter plate 13, and the scraper 14 is threadedly connected with the screws 16.

[0033] Mounting plates 15 are fixedly connected to the support part 3 and the hot channel water retaining platform 12 respectively corresponding to the two ends of the screw 16. The lower surface of the mounting plate 15 is fixedly connected to the support part 3 or the hot channel water retaining platform 12 through two support rods 18 arranged in parallel, and a flowing water area is formed through the area between the two support rods 18. A driving motor 17 for driving the screw 16 to rotate is fixedly connected to the mounting plate 15 at the upper part.

[0034] The height of the cold channel water retaining platform 11 is higher than that of the hot channel water retaining platform 12, and the upper end of the hot channel water retaining platform 12 forms an overflow platform.

[0035] In the cooling tower 1, an alternately arranged cold channel 4 and hot channel 5 are formed through the area between adjacent support parts 3. The cold channel water retaining platform 11 and the hot channel water retaining platform 12 face the cold channel 4 and the hot channel 5 respectively.

[0036] Both the cold-channel water baffle 11 and the hot-channel water baffle 12 are L-shaped and are arranged oppositely. The horizontal plate section of the cold-channel water baffle 11 is fixedly connected to the upper end of the support part 3, and the horizontal plate section of the hot-channel water baffle 12 is fixedly connected to the side wall of the support part 3 within the hot channel 5.
