Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a cooling tower device and an air conditioning system. Background Art

[0002] In central air conditioning water systems, during operation, open cooling towers circulate water within the water collection tray for extended periods. Due to the inherent hardness of the water and the environmental conditions surrounding the equipment, this can easily lead to scaling, corrosion, and scale deposition on heat exchange equipment and pipes, impacting the equipment's heat exchange performance. Furthermore, algae growth can also affect the water quality. Therefore, during cooling tower operation, chemicals or solid cakes must be regularly added to the circulating water to descale and remove algae. Prior art methods typically involve manually measuring the circulating water's quality parameters regularly, calculating the required amount of chemicals or solid cakes based on these parameters, and then having workers add the chemicals or solid cakes to the water collection tray. However, the applicant discovered that these prior art descaling and algae removal methods present complex maintenance, high labor intensity, and labor costs. Furthermore, manual chemical application is a one-time process, which can lead to excessively high concentrations in certain areas, causing chemical corrosion to cooling pipes and other heat exchange equipment. Manual chemical application can also lead to chemical overuse, further increasing operating costs, corroding equipment, and causing environmental damage from wastewater.

[0003] The prior art discloses a descaling closed cooling tower device, which includes a tower body, a coil disposed in the tower body, and a cooling water outlet and a cooling water inlet of the coil passing through the side wall of the tower body. The tower body is provided with a spray assembly and an exhaust assembly for heat exchange with the coil. The spray assembly includes a water collecting tray located at the bottom of the tower body, and a descaling assembly is provided at the water collecting tray. Furthermore, the descaling assembly includes a drug dosing tank and a drug dosing pump outside the tower body, and the drug dosing tank is connected to the drug dosing pump, and the liquid outlet of the drug dosing pump is connected to the water collecting tray. Although the device can perform descaling by automatically dispensing drugs, the device still has at least the following defects: (1) The device dispenses drugs or drug cakes into the water collecting tray, and the water in the water collecting tray is relatively still, so that the added drugs or drug cakes cannot be fully mixed with the water. Often, the drug concentration in the water near the drugs or drug cakes is high, and the drug concentration in the water away from the drugs or drug cakes is low. The agent or drug cake cannot be fully mixed with water, which not only makes the agent's treatment effect on the cooling water uneven, but also the water quality parameters measured by the monitoring device cannot accurately reflect the overall water quality in the cooling tower, which may lead to the abuse of the agent and increase the operating cost. (2) The drug dosing tank and drug dosing pump are set outside the tower body, which makes the cooling tower device occupy a large area. It can be seen that the space utilization rate of the device is not high, and its structure and equipment layout need to be optimized.

[0004] Therefore, it is urgent to improve the cooling tower device in the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0032] The following is attached with the instruction manual Figures 1 to 3 The cooling tower device and the air-conditioning system of the present invention are described in detail in Examples 1 and 2.

[0033] Example 1

[0034] This embodiment describes the cooling tower device of the present invention in detail.

[0035] The cooling tower device of this embodiment includes a tower body 1 and a dosing component 2. Figure 1 As shown. Preferably, a heat exchange circulation mechanism is provided inside the tower body 1, and the heat exchange circulation mechanism is connected to the cooling water supply pipe. The heat exchange circulation mechanism is used to exchange heat with the cooling water entering the tower body 1; the dosing component 2 is connected to the heat exchange circulation mechanism, and the dosing component 2 is used to add a reagent into the heat exchange circulation mechanism, and the added reagent enters the heat exchange circulation mechanism and flows with the cooling water, as shown. Figure 1 A fan 18 is provided above the tower body 1. Cooling water enters the tower body 1 through the water inlet 17 and then flows through the heat exchange circulation mechanism to exchange heat with the air. After the heat exchange, the cooling water enters the water collecting tray 14 and then flows out through the water outlet 16. Figure 1 and Figure 2 The dosing assembly 2 of this embodiment is not limited to being used in cooling towers, but can also be used in other heat exchange devices, such as a heat pump system for air conditioners.

[0036] Compared to the prior art solution of adding a reagent to a water collection tray, the cooling tower device of this embodiment adds a reagent to a heat exchange circulation mechanism, allowing the added reagent to mix with the relatively moving cooling water. During the mixing and flowing of the cooling water and the reagent, the uniformity of the mixing of the two is improved, thereby making the treatment effect of the reagent on the cooling water uniform. On the other hand, the improved uniformity of the mixing of the cooling water and the reagent also allows the water quality parameters measured by the monitoring device to accurately and effectively reflect the overall water quality in the cooling tower, avoiding the problem of reagent abuse due to inaccurate monitoring data, thereby reducing the operating cost of the equipment. That is, the cooling tower device of this embodiment solves the technical problem that the prior art cooling tower device places the reagent or medicine cake into the water collection tray, so that the added reagent or medicine cake cannot be fully mixed with the water, resulting in uneven treatment effect of the reagent on the cooling water and the water quality parameters measured by the monitoring device cannot accurately reflect the overall water quality in the cooling tower.

[0037] According to a preferred embodiment, the heat exchange circulation mechanism includes a diverter assembly and a spray assembly, wherein the diverter assembly is connected to the cooling water supply pipe, and the diverter assembly is also connected to the spray assembly. The diverter assembly is used to divert the cooling water entering the tower body 1 and then transport it to the spray assembly; the dosing assembly 2 is connected to the diverter assembly, such as Figure 1 As shown. Preferably, the diversion assembly includes a diversion pipe 10 and a delivery pipe 11, and the spray assembly includes a water distribution pipe 12 and a filler 13, wherein the diversion pipe 10 is connected to the cooling water supply pipe, the number of delivery pipes 11 is multiple, and the two ends of the delivery pipe 11 are respectively connected to the diversion pipe 10 and the water distribution pipe 12, and the filler 13 is located below the water distribution pipe 12; the dosing assembly 2 is connected to the diversion pipe 10, as shown in FIG. Figure 1 As shown. In the cooling tower device of the preferred technical solution of this embodiment, after the cooling water enters the tower body 1, it can flow through the diverter pipe 10, the delivery pipe 11, the water distribution pipe 12 and the filler 13 in sequence, and the dosing component 2 of the preferred technical solution of this embodiment is connected with the diverter pipe 10, so that the added agent can flow through the diverter pipe 10, the delivery pipe 11, the water distribution pipe 12 and the filler 13 in sequence with the cooling water. In the process of the mixing flow of cooling water and agent, the mixing uniformity of the two can be improved, so that not only the treatment effect of the agent on the cooling water can be uniform, but also the water quality parameters measured by the monitoring device can accurately and effectively reflect the overall water quality in the cooling tower, avoiding the problem of agent abuse due to inaccurate monitoring data, thereby reducing the operating cost of the equipment.

[0038] According to a preferred embodiment, a water collecting tray 14 is further provided inside the tower body 1, and the water collecting tray 14 is provided below the heat exchange circulation mechanism. Figure 1 Preferably, the dosing assembly 2 is arranged in the water collecting tray 14, and the dosing assembly 2 is located at the maintenance passage 15 of the tower body 1, as shown. Figure 3The tower body 1 is provided with an inspection door 19, and after the inspection door 19 is opened, the inspection passage 15 can be entered. Figure 2 As shown. The cooling tower device of the preferred technical solution of this embodiment is provided with a water collecting tray 14 below the heat exchange circulation mechanism. After the cooling water flows through the filler 13, it drips into the water collecting tray 14, and is collected into cooling return water through the water collecting tray 14 and returned to the air-conditioning system to complete the cooling heat exchange cycle. Furthermore, the dosing component 2 is provided in the water collecting tray 14, and the dosing component 2 is located at the maintenance passage 15 of the tower body 1. On the one hand, the internal space of the tower body 1 can be fully utilized, while ensuring that the dosing component 2 does not interfere with the air circulation channel, thereby avoiding affecting the heat exchange effect of the cooling water. On the other hand, when the operation and maintenance personnel regularly inspect the interior of the tower body 1, they can also check the amount of medicine in the dosing component 2 and replenish it in time when the amount of medicine is insufficient, thereby shortening the maintenance time of the operation and maintenance personnel.

[0039] According to a preferred embodiment, the cooling tower device further comprises a water quality monitoring component 3, such as Figure 1 or Figure 2 Preferably, the water quality monitoring component 3 is located at the water outlet 16 at the bottom of the tower body 1, and the water quality monitoring component 3 is used to monitor the water quality parameters at the water outlet 16, such as Figure 1 or Figure 2 As shown. More preferably, the water quality monitoring component 3 is located at the straight pipe section of the water outlet 16. The tower body 1 in the prior art avoids water pump cavitation, and the height of the cooling tower water outlet is relatively large, resulting in a large space at the bottom of the cooling tower. The water quality monitoring component 3 of the preferred technical solution of this embodiment is located at the water outlet 16 at the bottom of the tower body 1, which can not only collect the water quality parameters of the water outlet of the tower body 1, but also make full use of the bottom space of the tower body 1, optimize the structure and equipment components of the tower body 1, and improve the space utilization rate of the tower body 1.

[0040] According to a preferred embodiment, the cooling tower device further includes a water supply component 4, such as Figure 1 As shown. Preferably, the outlet of the water supply assembly 4 is connected to the water collection pan 14, and the water supply assembly 4 is used to supply water to the water collection pan 14. More preferably, the water supply assembly 4 includes a water supply valve and a water supply pipeline 41. The two ends of the water supply pipeline 41 are respectively connected to the municipal water source and the water collection pan 14. The water supply valve is set on the water supply pipeline 41. By opening the water supply valve, water can be supplied to the water collection pan 14 through the municipal water source. By closing the water supply valve, the water flow path between the municipal water source and the water collection pan 14 can be cut off. Figure 1As shown. The pH value of the cooling water needs to be maintained between 6.5 and 8.0. In the prior art, the pH value of the cooling water is generally adjusted by adding chemicals. This method can easily cause the cooling water to be over-acidic or over-alkaline, thereby accelerating the corrosion or local damage of the tower body 1 or the air-conditioning pipe. Compared with the method of adding chemicals to adjust the pH value in the prior art, the preferred technical solution of this embodiment is to add water to the water collection tray 14 through the water replenishment component 4, thereby adjusting the pH value of the cooling water to be within the required range, thereby avoiding the problem of the cooling water being over-acidic or over-alkaline, and also avoiding corrosion or local damage to the tower body 1 or the air-conditioning pipe.

[0041] According to a preferred embodiment, the cooling tower device further comprises an overflow component 5, such as Figure 1 or Figure 2 Preferably, the overflow assembly 5 is connected to the water collecting tray 14, and when the water in the water collecting tray 14 exceeds a preset water level, the overflow assembly 5 is used to discharge the water exceeding the preset water level, as shown in FIG. Figure 1 or Figure 2 As shown. More preferably, the overflow assembly 5 is, for example, an overflow pipe. The cooling tower apparatus of the preferred technical solution of this embodiment further includes an overflow assembly 5. When water is added to the water collection pan 14 via the water supply assembly 4, the water level in the water collection pan 14 rises. When the water in the water collection pan 14 exceeds a preset water level, the water in the water collection pan 14 is discharged into the drain trough 7 via the overflow assembly 5 and then discharged outdoors.

[0042] According to a preferred embodiment, the cooling tower device further comprises a sewage discharge component 8, such as Figure 1 or Figure 2 Preferably, the sewage discharge assembly 8 is connected to the water collecting tray 14, and the sewage discharge assembly 8 is used to discharge the dirt in the water collecting tray 14 into the drainage trough 7, as shown. Figure 1 or Figure 2 More preferably, the sewage discharge component 8 is, for example, a sewage pipe. The cooling tower device of the preferred technical solution of this embodiment further includes a sewage discharge component 8, which discharges the dirt in the water collecting tray 14 through the sewage discharge component 8, which is beneficial to improving the water quality in the tower body 1.

[0043] According to a preferred embodiment, the dosing component 2 is used to add reagents to the heat exchange circulation mechanism in batches. The batch addition of reagents in this embodiment refers to adding the required reagents to the heat exchange circulation mechanism in multiple batches. In the cooling tower device of the preferred technical solution of this embodiment, the dosing component 2 is used to add reagents to the heat exchange circulation mechanism in batches. This can avoid corrosion problems caused by excessive local concentration of reagents due to a single dose of reagents. It can also ensure the continuity and effectiveness of water quality parameters, avoid the problem of reagent abuse due to inaccurate monitoring data, thereby reducing the operating costs of the equipment and reducing the harm caused by drainage to the environment.

[0044] According to a preferred embodiment, the cooling tower device further comprises a control cabinet 6, such as Figure 1 Preferably, the dosing component 2, the water quality monitoring component 3 and the water replenishing component 4 are all connected to the control cabinet 6. The water quality monitoring component 3 sends the monitored water quality parameter information to the control cabinet 6, and the control cabinet 6 controls the working status of the dosing component 2 and the water replenishing component 4 based on the received water quality parameters. Figure 1 The cooling tower device of the preferred technical solution of this embodiment further includes a control cabinet 6, which enables the cooling tower device to automatically control the working states of the dosing component 2 and the water replenishment component 4 based on the water quality parameter information detected by the water quality monitoring component 3, thereby automatically improving the cooling water quality. Compared with the manual processing method in the prior art, the cooling tower device of the preferred technical solution of this embodiment greatly reduces the labor intensity of workers and can also reduce one workstation, thereby reducing labor costs.

[0045] According to a preferred embodiment, the dosing assembly 2 includes a first dosing assembly and a second dosing assembly, which are respectively arranged on both sides of the maintenance channel 15, and the first dosing assembly is used to add scale inhibitors to the heat exchange circulation mechanism in batches, and the second dosing assembly is used to add bactericides and algaecides to the heat exchange circulation mechanism in batches. Figure 3As shown. Preferably, the scale inhibitor can be a conventional scale inhibitor on the market, specifically a chemical agent that can reduce the structure and deposition of calcifications such as calcium carbonate and calcium phosphate. The bactericidal algaecide can also be a conventional bactericidal algaecide on the market. Specifically, the bactericidal algaecide mainly eliminates and inhibits algae and pathogens in the cooling water through the chloride ions in the chemical agent. In the cooling tower device of the preferred technical solution of this embodiment, the dosing component 2 includes a first dosing component and a second dosing component. Different agents are stored in the first dosing component and the second dosing component so that corresponding agents can be added according to the real-time monitoring of the water quality to achieve the purpose of improving the cooling water quality, thereby improving the performance and service life of the equipment. On the other hand, in the cooling tower device of the preferred technical solution of this embodiment, the first dosing assembly adds scale inhibitors to the heat exchange circulation mechanism in batches, and the second dosing assembly adds bactericides and algaecides to the heat exchange circulation mechanism in batches. This can avoid corrosion problems caused by excessive local concentrations of scale inhibitors or bactericides caused by a single addition. It can also ensure the continuity and effectiveness of water quality parameters, avoid the problem of drug abuse caused by inaccurate monitoring data, thereby reducing the operating costs of the equipment and the harm caused by wastewater to the environment. Thirdly, the first dosing assembly and the second dosing assembly of the preferred technical solution of this embodiment are respectively arranged on both sides of the maintenance channel 15. This not only fully utilizes the internal space of the tower body 1, but also ensures that the dosing assembly 2 does not interfere with the air circulation channel and avoids affecting the heat exchange effect of the cooling water. In addition, during regular inspections of the interior of the tower body 1, the operation and maintenance personnel can simultaneously check the amount of drug in the dosing assembly 2 and replenish it in time if the amount is insufficient, thereby shortening the maintenance time of the operation and maintenance personnel.

[0046] According to a preferred embodiment, the first dosing assembly includes a first medicine box 211 and a first medicine pump 212. The first medicine box 211 is used to store scale inhibitors. The first medicine box 211 is connected to the first medicine pump 212. The liquid outlet of the first medicine pump 212 is connected to the shunt pipe 10. The second dosing assembly includes a second medicine box 221 and a second medicine pump 222. The second medicine box 221 is used to store bactericides and algaecides. The second medicine box 221 is connected to the second medicine pump 222. The liquid outlet of the second medicine pump 222 is connected to the shunt pipe 10. Figure 3As shown. Preferably, the first chemical pump 212 and the second chemical pump 222 are connected to the control cabinet 6, and the control cabinet 6 controls the working status of the first chemical pump 212 and the second chemical pump 222 based on the received water quality parameters. In the cooling tower device of the preferred technical solution of this embodiment, when the first chemical pump 212 is in the open state, the scale inhibitor in the first chemical tank 211 can be injected into the heat exchange circulation mechanism, thereby preventing the formation of scale such as calcium carbonate and calcium phosphate in the cooling water, preventing scaling corrosion and scale deposition of heat exchange equipment and pipelines, and forming a protective film on the surface to reduce the corrosion rate; when the first chemical pump 212 is in the closed state, the passage between the first chemical tank 211 and the heat exchange circulation mechanism is disconnected. Similarly, when the second chemical pump 222 is in the open state, the bactericidal algaecide in the second chemical tank 221 can be injected into the heat exchange circulation mechanism to increase the chloride ion concentration in the cooling water, thereby preventing the growth of bacteria in the cooling water, inhibiting algae, and avoiding pipe blockage; when the second chemical pump 222 is in the closed state, the passage between the second chemical tank 221 and the heat exchange circulation mechanism is disconnected.

[0047] According to a preferred embodiment, the water quality monitoring component 3 includes a conductivity sensor, a chloride ion concentration sensor, and a pH sensor, all of which are connected to the control cabinet 6. Preferably, when the conductivity sensor detects that the outlet water conductivity is greater than a preset conductivity, the control cabinet 6 controls the first dosing component to be in an open state, thereby allowing the first dosing component to add scale inhibitors to the heat exchange circulation mechanism in batches. When the conductivity sensor detects that the outlet water conductivity is less than or equal to the preset conductivity, the control cabinet 6 controls the first dosing component to be in an closed state, thereby stopping the addition of scale inhibitors to the heat exchange circulation mechanism. When the chloride ion concentration sensor detects that the outlet water chloride concentration is less than the preset chloride concentration, the control cabinet 6 controls the second dosing component to be in an open state, thereby allowing the second dosing component to add bactericides and algaecides to the heat exchange circulation mechanism in batches. When the chloride ion concentration sensor detects that the outlet water chloride concentration is greater than or equal to the preset chloride concentration, the control cabinet 6 controls the water replenishment component 4 to be in an open state, thereby allowing the water replenishment component 4 to replenish the heat exchange circulation mechanism and appropriately reduce the chloride concentration. When the pH sensor detects that the outlet water pH is outside the preset pH range, the control cabinet 6 activates the water replenishment assembly 4, allowing water to be replenished into the water collection tray 14. More preferably, the preset conductivity is 800 μs / cm; the preset chloride ion concentration is determined based on local conditions, for example, 100 mg / L; and the preset pH range is 6.5 to 8.0. Without limitation, the water quality monitoring assembly 3 may also include other sensors to monitor other parameters of the cooling water.
