Description

Technical Field

[0001] The utility model relates to the technical field of integrated cooling stations, in particular to an integrated cooling station with automatic dosing and sewage discharge. Background Art

[0002] In modern buildings and industrial facilities, the cooling water system of the integrated cooling station plays a crucial role, especially in the operation of air conditioning and refrigeration equipment. However, the cooling water circulation of such systems is often open, and the cooling tower, as a key component, is used to dissipate the heat in the cooling water into the atmosphere. Although this design helps to effectively utilize energy, it also brings a series of problems, especially in terms of water quality management and equipment maintenance.

[0003] The environmental conditions inside the cooling tower, including temperature, humidity, and light, provide an ideal breeding ground for the growth of microorganisms. Especially algae, their rapid reproduction on the surface of the cooling tower packing not only hinders the effective heat exchange between water and air, reduces the cooling efficiency, but also accelerates the aging process of the packing, increases the maintenance cost and replacement frequency. In addition, the recycled use of cooling water causes the concentration of minerals and dissolved solids to gradually increase after multiple evaporations in the cooling tower. When the concentration of these substances reaches the saturation point, scale will form on the inner wall of the copper pipe of the condenser. The accumulation of scale significantly reduces the heat exchange efficiency, increases the energy consumption of the main engine, and thus affects the overall performance and economy of the system. As disclosed in the patent 202123311994.3, the automatic sewage discharge control device for the cooling tower avoids the increase of scale by setting up a structure for automatic drainage and sewage discharge. However, this method can only drain the water. Although it can reduce the generation of scale to a certain extent, it cannot reduce or avoid the generation of algae, bacteria, etc.

[0004] Therefore, the existing cooling water systems have obvious deficiencies in maintaining water quality stability and preventing the formation of biofilms and scale, which not only limits the long-term reliable operation of the systems, but may also cause additional energy waste and environmental problems. Summary of the Invention

[0005] The utility model provides an integrated cooling station with automatic dosing and sewage discharge for the problems of the prior art. By adding agents such as algaecides into the cooling tower through a dosing mechanism, the algaecides will delay the growth of algae in the cooling tower after being mixed with the water in the cooling tower, and cooperate with the sewage discharge mechanism, which timely discharges the corresponding high-concentration water, so as to reduce the formation of scale, bacteria, etc. in the cooling tower.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions: An integrated cooling station with automatic chemical dosing and sewage discharge, including a cooling tower. A water collecting tray is installed inside the cooling tower. It also includes a chemical dosing mechanism and a sewage discharge mechanism. The chemical dosing mechanism includes a chemical storage container, a chemical dosing driving member, and a connecting pipe. The chemical storage container is communicated with the water collecting tray through the connecting pipe. The chemical dosing driving member is used to pump the chemical in the chemical storage container into the connecting pipe. The sewage discharge mechanism includes a drainage pipeline and a control valve. The control valve is installed on the drainage pipeline. The inlet of the drainage pipeline is installed on the cooling tower and is communicated with the cooling tower. A first liquid level sensor is installed on the cooling tower, and the first liquid level sensor is used to detect the water volume in the cooling tower.

[0007] Preferably, the chemical dosing mechanism further includes a second liquid level sensor. The second liquid level sensor is installed on the chemical storage container and is used to detect the chemical storage volume in the chemical storage container.

[0008] Preferably, the chemical dosing mechanism further includes a mounting rack, and the chemical storage container is installed on the mounting rack.

[0009] Preferably, the mounting rack includes a mounting plate and support columns. The support columns are installed at the bottom of the mounting plate. A limiting groove for assembling the chemical storage container is opened at the top of the mounting plate.

[0010] Preferably, an installation groove is opened at the top of the chemical storage container. A fixing plate is installed in the installation groove. The chemical dosing driving member is installed on the fixing plate through screws.

[0011] Preferably, support plates are installed on both sides of the fixing plate. The support plates are locked to the chemical storage container through screws. The support plates form a cavity between the fixing plate and the chemical storage container.

[0012] The beneficial effects of the present utility model:

[0013] An integrated cooling station with automatic chemical dosing and sewage discharge provided by the present utility model adds chemicals such as algaecide to the cooling tower through the chemical dosing mechanism. The chemical dosing mechanism adds chemicals to the cooling tower in a timely manner according to the water volume in the cooling tower. After the algaecide is mixed with the water in the cooling tower, the growth of algae in the cooling tower will be delayed. And in cooperation with the sewage discharge mechanism, the sewage discharge mechanism timely discharges the corresponding high-concentration water, thereby reducing the formation of scale bacteria, etc. in the cooling tower. This embodiment effectively slows down the growth of algae and the scaling of cooling water, improves the heat transfer efficiency of the packing in the cooling tower and the condenser, and increases the service life of the packing and the heat exchange tubes in the condenser.

Specific embodiments

[0020] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings.

[0021] An integrated cooling station for automatic chemical dosing and sewage discharge provided in this embodiment, such as Figures 1 to 3 , includes a cooling tower 1. A water collecting tray is installed inside the cooling tower 1. It further includes a chemical dosing mechanism and a sewage discharge mechanism. The chemical dosing mechanism includes a chemical storage container 2, a chemical dosing driving member 3, and a connecting pipe 4. The chemical storage container 2 is communicated with the water collecting tray through the connecting pipe 4. The chemical dosing driving member 3 is used to pump the chemical in the chemical storage container 2 into the connecting pipe 4. The sewage discharge mechanism includes a drainage pipeline 5 and a control valve 6. The control valve 6 is installed on the drainage pipeline 5. The inlet of the drainage pipeline 5 is installed on the cooling tower 1 and is communicated with the cooling tower 1. The cooling tower 1 is equipped with a first liquid level sensor, and the first liquid level sensor is used to detect the water volume in the cooling tower 1.

[0022] Specifically, in this embodiment, a chemical dosing mechanism is added to add chemicals such as algaecide to the water collecting tray of the cooling tower 1. The algaecide is stored in the chemical storage container 2, and the chemical is transported to the water collecting tray of the cooling tower through a chemical dosing pump and a chemical dosing connecting pipe 4. The working mode of the chemical dosing driving member 3 can be: by setting a total control device and setting a predetermined time, that is, at regular time intervals, the total control device will regularly start the chemical dosing driving member 3. The chemical dosing driving member 3 will then pump the algaecide in the chemical storage container 2 into the water collecting tray in the cooling tower 1 through the connecting pipe 4. After the algaecide is mixed with the water in the cooling tower, the growth of algae in the cooling tower will be delayed. Further, in this embodiment, the sewage discharge mechanism is used to regularly discharge the water with a high ion concentration in the cooling tower 1, thereby reducing the formation of water scale in the cooling tower 1. Furthermore, in this embodiment, the water quality stability can be improved and the formation of biofilm and water scale can be prevented, ensuring that the cooling tower 1 can operate reliably for a long time.

[0023] Among them, the chemical dosing mechanism further includes a second liquid level sensor 7. The second liquid level sensor 7 is installed in the chemical storage container 2 and is used to detect the chemical storage amount in the chemical storage container 2. The second liquid level sensor 7 is signal-connected to the total control device. A minimum chemical amount liquid level of the chemical storage container 2 is set. When the second liquid level sensor 7 detects that the chemical amount in the chemical storage container 2 has dropped to the minimum chemical amount liquid level, the detection signal will be transmitted to the total control device, and the total control device will cause the chemical dosing driving member 3 to suspend operation and wait for the staff to add chemicals before starting to work again.

[0024] As Figures 1 to 3 shown, in this embodiment, a mounting frame is provided. The mounting frame is used to assemble the chemical storage container 2. The mounting frame includes a mounting plate 8 and support columns 9. The support columns 9 are installed at the bottom of the mounting plate 8. A limiting groove 10 for assembling the chemical storage container 2 is opened at the top of the mounting plate 8. Specifically, as Figure 3 and Figure 4 shown, the mounting plate 8 is provided with a limiting elastic piece 14. The limiting elastic piece 14 is arranged on the outer periphery of the limiting groove 10. The limiting elastic piece 14 is inclined. One end of the limiting elastic piece 14 is fixed to the mounting plate 8. After the chemical storage container 2 is assembled into the limiting groove 10, the other end of the limiting elastic piece 14 abuts against the chemical storage container 2, thereby avoiding the situation that the chemical storage container 2 falls off during use, improving the use safety of the chemical storage container 2, and the setting of the limiting elastic piece 14 can be applicable to chemical storage containers 2 of different sizes, with high use flexibility.

[0025] As Figure 3As shown in the figure, an installation groove 11 is provided at the top of the medicine storage container 2. A fixing plate 12 is installed in the installation groove 11, and the medicine adding driving member 3 is installed on the fixing plate 12 by screws. Specifically, support plates 13 are installed on both sides of the fixing plate 12. The support plates 13 are locked to the medicine storage container 2 by screws. The support plates 13 form a cavity between the fixing plate 12 and the medicine storage container 2. In this embodiment, the medicine adding driving member 3 can be selected as a driving pump. The medicine adding driving member 3 is installed on the fixing plate 12 and locked by screws. The support plates 13 make there be a cavity between the fixing plate 12 and the medicine storage container 2, so that the medicine adding driving member 3 does not directly contact the medicine storage container 2. The heat generated during the working process of the medicine adding driving member 3 will not affect the medicine storage container 2. At the same time, the cavity is also convenient for the heat dissipation of the medicine adding driving member 3.

[0026] In this embodiment, the control valve 6 of the sewage discharge mechanism is in signal connection with the total control device. A liquid level sensor can be arranged in the cooling tower 1. When the liquid level sensor in the cooling tower 1 detects that the water volume in the cooling tower 1 drops to a preset value, the total control device controls to open the liquid level sensor to timely discharge the remaining high-concentration water, thereby avoiding the formation of water scale in the cooling tower 1.
