Description

Technical Field

[0001] This utility model relates to the field of brine treatment technology, specifically to an anti-scaling device for brine pretreatment. Background Technology

[0002] In many industrial sectors such as chemical engineering, food processing, and seawater desalination, brine pretreatment is a crucial step. Its purpose is to remove impurities, suspended solids, and harmful ions from the brine, thus providing brine that meets quality requirements for subsequent production processes. However, scaling has consistently been a major challenge for companies during brine pretreatment.

A second circulating pump is installed on the circulating return water pipe. This solution is a butyl acetate circulating cooling water quantum ring anti-scaling device. Through the quantum tube loop, it can effectively store the vibration waves of water molecules and related substances in the water, continuously releasing ultra-fine vibration waves that act on the cooling pool and pipes, causing changes in the microscopic properties of the substances, effectively removing scale from the cooling pool and pipes, and killing bacteria and algae in the water, thus preventing scale formation. Moreover, the use of quantum ring technology completely eliminates the generation of waste brine, reduces the frequency of heat exchanger cleaning, and replaces water treatment chemical additives.

[0004] However, the anti-scaling device provided by the aforementioned patent is not suitable for brine treatment. Currently, chlor-alkali plants use a centrifugal pump and automatic valve control system in the primary brine pretreatment process. During operation, the automatic valve is prone to scaling, which narrows the flow channel and affects the production load of the primary refined brine. Therefore, there is an urgent need in the market for an anti-scaling device that can solve the problem of brine treatment. Utility Model Content

[0005] The purpose of this invention is to provide an anti-scaling device for brine pretreatment, which aims to improve upon existing anti-scaling devices that are not suitable for brine treatment and cannot effectively solve the scaling problem during brine treatment.

[0006] This utility model is implemented as follows:

[0007] A scale-preventing device for brine pretreatment includes a centrifugal pump, a frequency converter electrically connected to the side of the centrifugal pump, and a guide pipe provided at the drain end of the centrifugal pump. The guide pipe and the centrifugal pump are detachably connected. An electromagnetic coil is wound on the guide pipe, and an electromagnetic generator is provided below the guide pipe. The electromagnetic generator and the electromagnetic coil are connected.

[0008] Preferably, the centrifugal pump is provided with a junction box on the top, a wire is provided on the side of the junction box, and a power connector is provided at the end of the wire, which is connected to the frequency converter.

[0009] Preferably, the centrifugal pump has a fixed foot at the bottom, the fixed foot has multiple fixing holes, and the output end of the centrifugal pump is connected to a pump head, the pump head has a suction port and a drain port, and the ends of the suction port and the drain port are provided with flanges.

[0010] Preferably, the inverter has a connection slot at the top, which is connected to a power plug; the inverter has mounting feet at the bottom of the back, which have multiple mounting holes; and the inverter has wiring terminals at the bottom.

[0011] Preferably, both ends of the guide pipe are provided with connecting discs, the connecting discs are provided with connecting holes, and the connecting discs are connected to the flanges by bolts.

[0013] Preferably, the electromagnetic generator has a connecting plate on its side, and the connecting plate has bolt holes for fixing the position of the electromagnetic generator.

[0014] Preferably, the electromagnetic generator has a control panel on its side, a plug slot at its top, and a connector connected to the plug slot; the electromagnetic generator also has a connecting wire on its side, with a power connector at the end of the connecting wire.

[0015] Preferably, the pump also includes a support base, which is disposed at the bottom of the centrifugal pump and is connected to the centrifugal pump by bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This invention involves installing a guide pipe at the outlet of a centrifugal pump, with a coil and an electromagnetic generator mounted on the guide pipe. The electromagnetic generator produces an alternating electromagnetic field of specific frequency and intensity. When brine flows through the pipe wound with the electromagnetic coil, the physical and chemical properties of calcium and magnesium ions in the brine change under the influence of the electromagnetic field. The crystallization habit of the ions is disrupted, making it difficult to form stable crystal nuclei, thereby reducing the formation and deposition of scale. Simultaneously, a frequency converter is connected to the side of the centrifugal pump to regulate its operating frequency, thus controlling the flow rate. This eliminates the need for automatic valves, avoiding the scaling problems associated with them.

[0019] 2. This utility model provides stable support for the centrifugal pump by installing a support base at the bottom of the centrifugal pump, thus ensuring its stable operation. Attached Figure Description
