Description

Technical Field

[0001] This utility model relates to the technical field of condenser water collection tanks, specifically to an evaporative condenser water collection tank. Background Technology

[0002] An evaporative condenser is a heat exchange device used for cooling cold storage. It consists of components such as a fan, condenser coil, heat exchange fins, and a water collection tank. The water collection tank is used to collect circulating water from the spray water circulation system, enabling the reuse of water resources. A search revealed an existing technology (publication number: CN202323099937.2) that describes an evaporative condenser water collection tank with a filtration function. The paper states that "this utility model, by using a filter plate, can filter the spray water and send it into the water collection tank. By using a spray mechanism, the filtered water can be reused, thereby improving the environmental performance of the device." However, in the existing technology, the water circulating in the collection tank evaporates as the spray water evaporates, leading to an increase in the mineral concentration in the circulating water. This minerals tend to deposit on the surface of the condenser coil, affecting the condenser's heat exchange efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, an evaporative condenser water collection tank is provided to solve the problem that in existing technologies, the mineral concentration in the circulating water increases as the sprayed water evaporates, which easily deposits on the surface of the condenser coil and affects the heat exchange efficiency of the condenser.

[0004] To achieve the above objectives, an evaporative condenser water collection tank is provided, comprising: a condenser body and a water collection tank chamber, wherein the water collection tank chamber is disposed inside the bottom end of the condenser body.

[0005] A detection probe is sealed and fixed in the front chamber of the water collection tank. The detection probe is electrically connected to a water quality analyzer. A mixing tank is connected to the right end of the water collection tank through a connecting pipe. A spray plate is connected to the rear end of the mixing tank through a liquid delivery pipe. An agitator is installed inside the mixing tank. A stirring motor is shaft-connected to the upper end of the agitator. A small conveying cylinder is distributed to the right of the stirring motor. A spiral blade is installed inside the small conveying cylinder through a rotating shaft. The lower end of the small conveying cylinder is connected to the inside of the mixing tank through a discharge pipe.

[0006] Furthermore, a circulating water pipe is connected to the left end of the water collection tank, and a filter screen frame is inserted and fixed inside the condenser body, with the filter screen frame located at the upper end of the water collection tank.

[0007] Furthermore, a stirring motor and a small conveying cylinder are fixed on the upper surface of the mixing tank, an electrically controlled valve one is installed on the surface of the liquid delivery pipe, and an electrically controlled valve two is installed on the surface of the discharge pipe.

[0008] Furthermore, a mixing tank is supported on the right side of the condenser body via a fixing plate, and a liquid outlet is provided on the inner wall of the rear side of the mixing tank; and a liquid delivery pipe is connected to the rear end of the liquid outlet.

[0009] Furthermore, an infusion pump is installed on the surface of the infusion tube, and a feeding hopper is fixed to the rear side of the upper end face of the small feeding cylinder.

[0010] Furthermore, a feed pipe is connected to the front side of the lower cylinder of the small feed cylinder, and a small motor is connected to the front end of the spiral blade through a rotating shaft. The small feed cylinder stores scale inhibitor particles.

[0011] Furthermore, the spray plate is fixedly installed on the inner wall of the water collection tank, and spray holes are equidistantly opened on the lower end face of the spray plate.

[0012] The beneficial effects of this utility model are as follows: the evaporative condenser water collection tank of this utility model utilizes a mixing tank, a delivery pipe, a delivery pump, a stirrer, a stirring motor, a spray plate, and a small delivery cylinder to form a scale inhibition mechanism. The scale inhibitor is added to the mixing tank through the small delivery cylinder, and the stirrer is controlled to dissolve and mix the circulating water flowing into the tank with the scale inhibitor. Then, the mixture is sprayed onto the circulating water in the water collection tank through the spray plate. This facilitates the interference of the nucleation and growth of mineral ions in the circulating water in the water collection tank, avoids the mineral scale in the circulating water in the water collection tank from forming on the surface of the condenser coil, reduces the dirt on the surface of the condenser coil, and ensures the overall heat exchange efficiency of the evaporative condenser.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4 As shown, this utility model provides an evaporative condenser water collection tank, including: a condenser body 1 and a water collection tank 3, wherein the water collection tank 3 is provided inside the bottom end of the condenser body 1.

[0020] A detection probe 32 is sealed and fixed in the front chamber of the water collection tank 3. The detection probe 32 is electrically connected to a water quality analyzer 31. The right end of the water collection tank 3 is connected to a mixing tank 4 through a connecting pipe 41. The rear end of the mixing tank 4 is connected to a spray plate 5 through a liquid delivery pipe 42. An agitator 44 is installed inside the mixing tank 4. A stirring motor 46 is shaft-connected to the upper end of the agitator 44. A small conveying cylinder 6 is distributed to the right of the stirring motor 46. A spiral blade 62 is installed inside the small conveying cylinder 6 through a rotating shaft. The lower end of the small conveying cylinder 6 is connected to the inside of the mixing tank 4 through a discharge pipe 63.

[0021] When the condenser body 1 is operating normally, some of the sprayed water does not evaporate and flows through the filter screen 2 into the water collection chamber 3. The water quality tester 31 detects the water quality in the water collection chamber 3. When the mineral concentration of the circulating water in the water collection chamber 3 increases, the electric control valve 43 opens briefly, and some water in the water collection chamber 3 flows into the mixing tank 4 and then automatically closes. At this time, the spiral blades in the small conveying cylinder 6 rotate and convey the scale inhibitor through the discharge pipe 63 into the mixing tank 4. The stirring motor 46 drives the stirrer 44 to mix and stir the scale inhibitor. After it is dissolved in the water, the delivery pump 45 delivers the dissolved and mixed water to the spray plate 5, so that the spray plate 5 sprays the water evenly into the water in the water collection chamber 3. This causes the scale inhibitor solution to interfere with the nucleation and growth of mineral ions in the circulating water in the water collection chamber 3, thereby achieving the scale inhibition effect in the water in the water collection chamber 3.

[0022] In this embodiment, a circulating water pipe 11 is connected to the left end of the water collection tank 3, and a filter screen frame 2 is inserted and fixed inside the condenser body 1. The filter screen frame 2 is located at the upper end of the water collection tank 3.

[0023] In a preferred embodiment, the circulating water pipe 11 pumps water from the water collection tank 3 to the spray mechanism of the evaporative condenser, spraying water onto the condenser bend and forcibly ventilating to cause the water film on the tube bundle surface to evaporate. Heat is transferred from the refrigeration vapor inside the tube to the water film outside the tube and evaporates into the atmosphere, achieving a condensation effect. The filter screen 2 removes impurities from the water that have not evaporated during the process.

[0024] In this embodiment, a stirring motor 46 and a small conveying cylinder 6 are fixed on the upper surface of the mixing tank 4. An electrically controlled valve 43 is installed on the surface of the liquid delivery pipe 42, and an electrically controlled valve 64 is installed on the surface of the discharge pipe 63. The mixing tank 4 is supported by a fixing plate on the right side of the condenser body 1. A liquid outlet is provided on the inner wall of the rear side of the mixing tank 4, and the rear end of the liquid outlet is connected to the liquid delivery pipe 42. A liquid delivery pump 45 is installed on the surface of the liquid delivery pipe 42, and a feeding hopper 61 is fixed on the rear side of the upper end face of the small conveying cylinder 6. The discharge pipe 63 is connected to the front side of the lower cylinder of the small conveying cylinder 6, and a small motor is connected to the front end of the spiral blade 62 through a rotating shaft. Scale inhibitor particles are stored inside the small conveying cylinder 6.

[0025] In a preferred embodiment, the stirring motor 46 drives the agitator 44 to rotate and dissolve the scale inhibitor particles, causing the water entering the mixing tank 4 to form a scale inhibitor solution. The first and second electrically controlled valves 43 and 64 open and close sequentially, allowing water from the collection tank 3 and the scale inhibitor particles from the small conveying cylinder 6 to enter the mixing tank 4. The feeding hopper 61 facilitates and quickly adds scale inhibitor particles to the small conveying cylinder 6, and the quantitative feeding of the scale inhibitor particles is controlled by the rotation time of the spiral blades 62 driven by the small motor.

[0026] In this embodiment, the spray plate 5 is fixedly installed on the inner wall of the water collection tank 3, and spray holes 51 are equidistantly opened on the lower end face of the spray plate 5.

[0027] In a preferred embodiment, the spray plate 5 disperses and sprays the scale inhibitor solution delivered by the infusion pipe 42 into the water collection chamber 3, so that the circulating water in the water collection chamber 3 can mix with the scale inhibitor solution, thereby interfering with the nucleation and growth of mineral ions in the circulating water in the water collection chamber 3 and generating soluble complexes.

[0028] This utility model's evaporative condenser water collection tank effectively solves the problem in the prior art where increased mineral concentration in circulating water easily deposits on the surface of the condenser coil, affecting the condenser's heat exchange efficiency. It facilitates interference with the nucleation and growth of mineral ions in the circulating water within the collection tank, preventing mineral scale buildup on the condenser coil surface, reducing scale buildup on the condenser coil surface, and ensuring the overall heat exchange efficiency of the evaporative condenser. It is suitable for evaporative condenser water collection tanks.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
