Description

Technical Field

[0001] This invention belongs to the field of silicon material preparation technology, and specifically relates to a system for preventing blockage of frozen brine. Background Technology

[0002] Chilled brine is commonly used in industry, especially in chemical and pharmaceutical sectors. Chilled brine requires the addition of a certain proportion of salt to the water because its temperature typically drops below 0°C. Adding salt prevents the brine from freezing; the freezing point varies depending on the salt ratio. Common salts include calcium chloride, magnesium chloride, and sodium chloride. To maintain a chilled brine temperature of around -15°C, a calcium chloride concentration of approximately 20% is required. Chloride ions in water are highly corrosive to metal pipes and equipment, so corrosion inhibitors are added to the chilled brine to inhibit chloride corrosion and extend equipment lifespan. However, after prolonged operation, chilled brine still accumulates many impurities. Furthermore, the materials used for heat exchange in industries like chemicals are often highly corrosive. If material leaks occur, the leaked material entering the chilled brine system will exacerbate corrosion of pipes and equipment.

[0003] The disadvantages of existing technology are as follows: 1. After long-term operation, the chilled brine will contain a large number of impurities, posing a risk of pipe blockage and significantly impacting normal production. Pipe blockage also requires manual unblocking. Current chilled brine systems only add a bag filter to a bypass on the water supply side. This filtration method uses multiple cycles to retain impurities in the chilled brine within the bag filter. However, after long-term operation, the impurity load in the chilled brine system is relatively high. For long-term operation, corrosive materials may enter the chilled brine system, and filtration relying solely on a single bag filter cannot meet normal operational requirements. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a system for preventing blockage of chilled brine. This system automatically senses the turbidity in the chilled brine, automatically replaces the chilled brine, and discharges the chilled brine rich in impurities from the filter. At the same time, it automatically replenishes chilled brine and corrosion inhibitors. The entire device operates automatically, so that the chilled brine can achieve the ideal effect and prevent the blockage of chilled brine pipelines from affecting normal production.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A system for preventing clogging of chilled brine includes a chilled brine generator connected to a brine supply tank via pipes, the brine supply tank connected to a distributor via pipes, and the distributor connected to the chilled brine generator via pipes. The brine supply tank is connected to a brine preparation tank and a filter via pipes, and the filter is connected to the pipes between the brine supply tank and the distributor via pipes.

[0007] Preferably, a brine pump is installed on the pipe between the brine supply tank and the distributor.

[0008] Preferably, a second pump and a level regulating valve are installed on the pipeline between the brine supply tank and the brine preparation tank.

[0009] Preferably, the filter is connected to a brine collection tank via a pipe, and the brine collection tank is connected to a first pump via a pipe.

[0010] Preferably, a flow regulating valve is installed on the pipe between the brine collection tank and the filter.

[0011] Preferably, a turbidity sensor is installed on the pipeline output by the brine pump. The turbidity sensor is electrically connected to a turbidity regulating valve, which is installed on the pipeline between the filter and the water distributor.

[0012] Preferably, the filter includes an inlet pipe, an outlet pipe, a drain pipe, an inner filter cylinder, and an outer cylinder.

[0020] Preferred solutions include Figures 1 to 3 As shown, a system for preventing clogging of chilled brine includes a chilled brine generator 1, which is connected to a brine supply tank 2 via a pipe. The brine supply tank 2 is connected to a distributor 5 via a pipe, and the distributor 5 is connected to the chilled brine generator 1 via a pipe. The brine supply tank 2 is connected to a brine preparation tank 7 and a filter 9 via pipes. The filter 9 is connected to the pipe between the brine supply tank 2 and the distributor 5 via a pipe.

[0021] Specifically, a brine pump 3 is installed on the pipe between the brine supply tank 2 and the distributor 5. A second pump 15 and a level regulating valve 16 are installed on the pipe between the brine supply tank 2 and the brine preparation tank 7. Figure 1 As shown, the liquid level signal of the liquid level regulating valve 16 is collected by the liquid level sensor 14.

[0022] Filter 9 is connected to brine collection tank 12 via a pipe, and brine collection tank 12 is connected to first pump 13 via a pipe. A flow regulating valve 10 is installed on the pipe between brine collection tank 12 and filter 9. Figure 1 As shown, the flow signal of the flow regulating valve 10 is acquired by the flow sensor 11.

[0023] A turbidity sensor 4 is installed on the output pipe of the brine pump 3. The turbidity sensor 4 is electrically connected to the turbidity regulating valve 8, which is installed on the pipe between the filter 9 and the water distributor 5.

[0024] The working principle is:

[0025] Chilled brine enters the brine supply tank via a chilled brine chiller unit. The brine supply tank contains a level sensor. Next to the brine supply tank is a brine preparation tank, where prepared chilled brine and some purchased chilled brine can be stored. The outlet pipe of the brine supply tank passes through a brine pump to a distributor. A turbidity sensor is located in the pipe between the brine pump and the distributor. When the turbidity of the chilled brine does not meet requirements, some chilled brine passes through a turbidity regulating valve 8 into a filter. The lower outlet of the filter is connected to a brine collection tank. Impurities in the chilled brine in the collection tank are pumped into the wastewater treatment system by a first pump. The filtered chilled brine returns to the brine supply tank. After passing through the distributor, the chilled brine reaches different users. After use, the brine is returned directly to the chilled brine chiller unit. Figure 1 As shown.

[0026] Furthermore, the filter 9 includes an inlet pipe 91, an outlet pipe 92, a drain pipe 93, an inner filter cylinder 94, and an outer cylinder. The inner filter cylinder 94 is disposed inside the outer cylinder. The inlet pipe 91 and the drain pipe 93 are disposed at both ends of the inner filter cylinder 94, and the drain pipe 93 is disposed on the outer wall of the outer cylinder. The filter includes an inlet pipe, an outlet pipe, a drain pipe, and an inner filter cylinder. During use, a filter screen is placed inside the inner filter cylinder. The lower end of the inner filter cylinder, where it connects to the drain pipe, is detachable for easy replacement of the filter screen. Figure 2 , Figure 3 As shown.

[0027] In this invention, all valves and pumps are controlled by PLC programming. Control logic: Turbidity regulating valve 8 is controlled by a turbidity sensor. It opens when the turbidity of the chilled brine in the pipeline reaches a certain reading and automatically closes after reaching the ideal state. The filter outlet flow regulating valve 10 is controlled by a flow sensor. It opens for 30 seconds and then automatically closes, and cannot be opened again for 3 minutes, after which the above action repeats. A low flow rate in the pipeline indicates a large amount of filter residue in the filter; to prevent pipeline blockage, the filter residue is discharged promptly. When the liquid level in the brine collection tank reaches a certain level, the first pump pumps the brine to the wastewater treatment system for processing. The liquid level regulating valve 16 at the outlet of the brine preparation tank is controlled by a liquid level sensor installed in the brine supply tank. It automatically closes after reaching a certain liquid level. The second pump is controlled by liquid level regulating valve 16; it automatically starts 5 seconds after liquid level regulating valve 16 opens. When the filter discharges filter residue, a small amount of chilled brine is also discharged, causing the liquid level in the brine supply tank to drop; the system needs to be replenished with chilled brine promptly. All control systems are only applicable when the chilled brine unit is running.
