Description

Technical Field

[0001] The present application relates to the technical field of water saving, and in particular to a water saving system. Background Art

[0002] In the process of utilizing waste heat to generate electricity, a cooling water pool is required. After running for a period of time, the liquid in the cooling water pool needs to be replaced, which results in a large consumption of production water. Summary of the invention

[0003] In view of the shortcomings of the prior art, one of the purposes of this application is to provide a water-saving system, which has the advantage of being able to save production water.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] A water-saving system includes a circulation pipeline and a cooling water pool. The circulation pipeline is used for water circulation of other systems. The circulating liquid in the circulation pipeline is demineralized water. When the liquid in the circulation pipeline is replaced, the discharged liquid is directed to the cooling water pool.

[0006] By adopting the above technical solution, the water in the circulation pipeline is discharged into the cooling water pool, which reduces the conductivity of the cooling water pool, reduces the replacement amount of the cooling tower water pool, and reduces the consumption of production water.

[0007] In a preferred example, the present application can be further configured as follows: when the liquid is replaced in the circulation pipeline, the salt content of the desalted water is judged. If it is less than the standard value, the discharged liquid is diverted to the cooling water pool. If it is greater than the standard value, a notification is made.

[0008] By adopting the above technical solution, that is, when the salt content is greater than the standard value, a notification is made, thereby avoiding the probability of water with a high salt content being discharged into the cooling water pool.

[0009] In a preferred example, the present application can be further configured as follows: the salt content of the liquid in the cooling water pool is determined. If it is greater than the standard value, the liquid in the cooling water pool is completely discharged, the liquid in the circulation pipeline is discharged into the cooling water pool, and additional liquid is added to the standard water level.

[0010] By adopting the above technical solution, that is, when the salt content of the liquid in the cooling water pool is greater than the standard value, the liquid in the cooling water pool is completely discharged and replaced, thereby effectively reducing the salt content of the liquid in the cooling water pool.

[0011] In a preferred example, the present application can be further configured as follows: if the salt content of the liquid in the cooling water pool is less than the minimum value, the liquid in the circulating pipeline is discharged into the cooling water pool until the liquid in the circulating pipeline is emptied, or the liquid in the cooling water pool reaches the maximum water level. When the liquid in the cooling water pool reaches the maximum water level, the liquid in the circulating pipeline is not discharged into the cooling water pool.

[0012] By adopting the above technical solution, when the salt content of the liquid in the cooling water pool is less than the minimum value, the liquid in the circulation pipeline is added to the cooling water pool until it is drained or reaches the highest water level.

[0013] In a preferred example, the present application can be further configured as follows: if the salt content of the liquid in the cooling water pool is greater than the minimum value and less than the standard value, an equal amount of water in the cooling water pool and the circulating pipeline is discharged, and then the water in the circulating pipeline is discharged into the cooling water pool.

[0014] By adopting the above technical solution, an equal amount of water is discharged, thereby reducing the salt content in the cooling water pool.

[0015] In a preferred example, the present application can be further configured as follows: if the water level in the cooling water pool is higher than the standard water level, the amount of water discharged is greater than the amount of water in the circulating pipeline, so that the remaining water in the cooling water pool plus the water in the circulating pipeline can reach the standard water level; if the water level in the cooling water pool is at the lowest water level, the liquid in the circulating pipeline is discharged into the cooling water pool, and additional liquid is added to the standard water level.

[0016] By adopting the above technical solution, that is, when the water in the circulation pipeline is discharged into the cooling water pool, the water level in the cooling water pool is judged, so that the water in the cooling water pool can meet the standards and have a low salt content.

[0017] In a preferred example, the present application can be further configured as follows: if the water level in the cooling water pool is lower than the minimum water level, the liquid in the circulation pipeline is discharged into the cooling water pool, and additional liquid is added to the standard water level, and the last time the liquid in the cooling water pool was adjusted is queried. If the interval time is less than the preset value, a notification is made.

[0018] By adopting the above technical solution, that is, when the water in the circulation pipeline is discharged into the cooling water pool, the water level is judged. If it is lower than the minimum water level, the last adjustment time is judged. If the interval is less than the preset value, it indicates that an abnormality may occur, and then a notification is made. DETAILED DESCRIPTION

[0019] The present application discloses a water-saving system, including a circulation pipeline and a cooling water pool. The circulation pipeline is used for water circulation of other systems. The circulating liquid in the circulation pipeline is desalted water. When the circulation pipeline performs liquid replacement, the discharged liquid is directed to the cooling water pool. When the circulation pipeline performs liquid replacement, the salt content of the desalted water is judged. If it is less than the standard value, the discharged liquid is directed to the cooling water pool. If it is greater than the standard value, a notification is made.

[0020] Determine the salt content of the liquid in the cooling water pool. If it is greater than the standard value, completely drain the liquid in the cooling water pool, drain the liquid in the circulation pipeline into the cooling water pool, and add additional liquid to the standard water level.

[0021] If the salt content of the liquid in the cooling water pool is less than the minimum value, the liquid in the circulating pipeline will be discharged into the cooling water pool until the liquid in the circulating pipeline is emptied or the liquid in the cooling water pool reaches the maximum water level. When the liquid in the cooling water pool reaches the maximum water level, the liquid in the circulating pipeline will not be discharged into the cooling water pool.

[0022] If the salt content of the liquid in the cooling water pool is greater than the minimum value and less than the standard value, an equal amount of water in the cooling water pool and the circulating pipeline is discharged, and then the water in the circulating pipeline is discharged into the cooling water pool. If the water level in the cooling water pool is higher than the standard water level, the amount of water discharged is greater than the amount of water in the circulating pipeline, that is, the water in the cooling water pool is first discharged to the standard water level, and then the water equal to the amount of water in the circulating pipeline is discharged again, so that the remaining water in the cooling water pool plus the water in the circulating pipeline can reach the standard water level. If the water level in the cooling water pool is at the minimum water level, the liquid in the circulating pipeline is discharged into the cooling water pool, and additional liquid is added to the standard water level. If the water level in the cooling water pool is lower than the minimum water level, the liquid in the circulating pipeline is discharged into the cooling water pool, and additional liquid is added to the standard water level, and the last time the liquid in the cooling water pool was adjusted is queried. If the interval time is less than the preset value, a notification is made. In the present application, the salt content can be judged by detecting the DTS value, or by other methods.

[0023] The implementation principle of this embodiment is: during use, the salt content of the water in the circulation pipeline is tested, and the salt content of the water in the cooling water pool is tested, and the water in the circulation pipeline is injected into the cooling water pool to supplement the water in the cooling water pool, thereby achieving the purpose of saving production water.

[0024] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
