Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water ring spray type glass fiber reinforced plastic cooling tower. Background Art

[0002] The FRP cooling tower is a device that utilizes the contact between water and air to dissipate waste heat generated in industry or refrigeration and air conditioning through evaporation. During operation, the dry air is pumped by the fan and enters the cooling tower from the air inlet network. The high-temperature water molecules with large saturated steam partial pressure flow toward the air with low pressure, and the hot and humid wastewater generated in the industrial process is sprinkled into the tower from the water seeding system. When water droplets come into contact with air, on the one hand, the air does not directly transfer heat, and on the other hand, due to the pressure difference between the water vapor surface and the air, evaporation occurs under the action of pressure, taking away the heat in the water, that is, evaporation heat transfer, thereby achieving the purpose of cooling.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN207351243U discloses a closed glass fiber reinforced plastic cooling tower, including a cooling tower, wherein a fan, a water collector, a spray system, a coil, and a water collection tank are sequentially arranged inside the cooling tower from top to bottom; a rib plate is arranged on the outer shell of the cooling tower, and a support frame is arranged at the bottom of the cooling tower; the fan is arranged at the top of the tower body, and a water collector is arranged at the lower end of the fan; a water collection tank is arranged at the bottom of the tower body, and a water pump is arranged on one side of the tower body, and the water pump and the water collection tank are connected through a spray pipe; the spray pipe is connected to the spray system of the cooling tower, and a coil is arranged inside the spray system, and the lower end of the coil is connected to a fluid inlet arranged on one side of the tower body, and the upper end of the coil is connected to a fluid outlet arranged on the upper part of the fluid inlet; an air inlet is arranged on one side of the cooling tower; a dust filter is arranged at the air inlet outside the cooling tower, and the dust filter and the sliding groove are detachably connected. The utility model adopts a closed water circulation, and the air inlet is a truncated cone, which increases the air circulation area and the temperature difference.

[0005] However, there are still some problems that need to be improved in the actual use of the above patent. The most obvious one is that before the remaining water after evaporative cooling is recovered to the water collection tank, the impurities in the water cannot be filtered, which may easily cause damage to the water pump during subsequent use.

[0006] To this end, we proposed a water ring spray type FRP cooling tower to solve the above-mentioned drawbacks. Utility Model Content

The fluid flows out from the top outlet of the tower body, and flows from the bottom of the annular coil 5 to the top of the annular coil 5. The heat emitted by the annular coil 5 is exchanged with the surrounding spray water and air. The fluid transfers the heat to the tower body through the annular coil 5 for heat dissipation. The water pump 4 draws water from the filter box 9 and transfers it to the fluid outlet 6 through the annular coil 5. The spray water transfers the converted heat to the air through the fan 3. The spray water and the air entering the air inlet 7 are heated by the annular coil 5, and part of the water evaporates. The water collector 2 at the top of the tower body collects the water taken away by the air evaporation, and the remaining water is recycled to the filter box 9 for The filter can be reused, wherein the driving motor 13 drives the scraper 15 to rotate, which can clear the filter 12, reduce the risk of clogging of the filter 12, and ensure the filtering effect and efficiency of the filter 12.

The fluid flows from the bottom of the annular coil 5 to the top of the annular coil 5. The heat emitted by the annular coil 5 exchanges heat with the surrounding spray water and air. The fluid transfers the heat to the tower body through the annular coil 5 to dissipate heat. The water pump 4 draws water from the filter box 9 and transfers it to the fluid outlet 6 through the annular coil 5. The spray water transfers the converted heat to the air through the fan 3. The spray water and the air entering the air inlet 7 are heated by the annular coil 5, and part of the water evaporates. The water collector 2 on the top of the tower body collects the air vapor.
