Description

Technical Field

[0001] The invention relates to the field of water treatment, in particular to a water treatment method, a crystallizer soft water treatment method. Background Art

[0002] In the process flow of the crystallizer soft water closed system in the prior art, the installation sequence of the pipe filter and the plate heat exchanger is unclear. Some pipe filters are installed at the rear end of the plate heat exchanger. The gap between the plate heat exchanger in the crystallizer soft water closed system is small, which leads to serious blockage of the plate heat exchanger, affecting the heat exchange efficiency and even affecting the safety supply in serious cases.

[0003] Therefore, it is necessary to develop new water treatment methods to overcome the above problems. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a water treatment method, which filters the impurities in the water by installing a pipeline filter at the front end of the plate heat exchanger, and at the same time adds corrosion inhibitors and scale inhibitors and bactericides to reduce system scaling and sludge growth, thereby solving the problem of blockage of the plate heat exchanger.

[0005] Technical solution: A water treatment method of the present invention is characterized in that: a pipeline filter is installed in the front section of the plate heat exchanger of the soft water closed system of the crystallizer to filter impurities in the water, and corrosion inhibitors and bactericides are added to perform dosing operations.

[0006] Among them, the water from the production plant goes to the pipe filter of the water treatment station, then to the plate heat exchanger for cooling, and then to the treatment of adding chemicals, and finally returns to the production user end.

[0007] Among them, when the pipeline filter is installed at the rear end of the plate heat exchanger, it is only necessary to move the filter to the front end of the plate heat exchanger during the shutdown of the production plant.

[0008] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention installs a pipeline filter at the front section of the plate heat exchanger in the closed system of the crystallizer soft water to filter out impurities in the water, and at the same time adds corrosion inhibitors and scale inhibitors and bactericides to reduce scaling and sludge growth in the system, greatly reducing the blockage rate of the plate heat exchanger, solving the problem of high water temperature in the water treatment system, especially in high temperatures in summer, ensuring safe and stable production operation, and also greatly reducing the workload of maintenance and saving a lot of manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0011] The water treatment method of the present invention is to install a pipeline filter at the front section of the plate heat exchanger of the soft water closed system of the crystallizer to filter the impurities in the water, and at the same time add corrosion inhibitors and bactericides for dosing operations. The water from the production plant goes to the pipeline filter of the water treatment station, then to the plate heat exchanger for cooling, then to the treatment of adding chemicals, and finally returns to the production user end. When the pipeline filter is installed at the rear end of the plate heat exchanger, it only needs to move the filter to the front section of the plate heat exchanger during the shutdown period of the production plant.

[0012] The present invention clarifies the installation sequence of the pipeline filter and the plate heat exchanger, and simultaneously adds corrosion inhibitors and scale inhibitors and bactericides to reduce scaling and slime growth in the system, reduce the risk of blockage of the plate heat exchanger, and ensure the water temperature and water pressure of the system water supply.

[0013] Example:

[0014] A water treatment pump station currently has 4 groups of 12 plate heat exchangers. In order to ensure the normal operation of production, a pipeline filter is installed in the front section of the plate heat exchanger when the production plant is shut down.

[0015] At present, the closed system of crystallizer soft water is equipped with pipeline filters. Some system pipeline filters are installed at the rear end of the plate heat exchanger. It is only necessary to move the filter to the front end of the plate heat exchanger during the shutdown of the production plant. During the operation of the system, corrosion inhibitors and bactericides are added to reduce the scaling and slime breeding of the system.
