Description

Technical Field

[0001] This utility model relates to a device for removing iron from condensate water. Background Technology

[0002] Condensate is saturated, high-temperature softened water, accounting for about 25% of the thermal energy value of steam. It is also clean distilled water, suitable for reuse as boiler feedwater. Iron removal is a crucial step in the steam condensate treatment process. Some users find their recycled condensate to be reddish or even soy sauce-colored. This is mainly because during the recycling process, the steel pipes and containers in contact with the condensate undergo oxidation and corrosion, generating iron oxide (Fe3O4, Fe2O3) particles and colloids. Since the incoming water is desalinated condensate, it contains very few cations, resulting in less electrochemical corrosion. The main task of condensate iron removal is to remove iron oxide particles and colloids from the water.

[0003] Existing iron removal devices mostly use high-temperature sintered ceramic filter media layers to remove iron from condensate. However, in order to ensure the iron removal effect, the pore size of the high-temperature sintered ceramic filter media layer is usually set to be small, which makes it easy to get clogged and affect the normal use of the iron removal device. Utility Model Content

[0004] This invention provides a condensate iron removal device to overcome the defects of existing technology.

[0005] The above objectives are achieved through the following scheme: A condensate iron removal device comprises an iron removal box, which is an arc-shaped box. Multiple upper magnetic rods are fixed on the upper part of the iron removal box. A chip collection hopper is provided at the bottom of the iron removal box corresponding to the upper magnetic rods. The chip collection hopper is threadedly connected to a chip collection cylinder. A lower magnetic rod is inserted into the chip collection cylinder. A water collection baffle for collecting water is fixed on the annular side wall inside the iron removal box.

[0006] The aforementioned condensate iron removal device has one end of the iron removal box fixed to the water inlet pipe and the other end fixed to the water outlet pipe. Beneficial effects

[0007] 1. This utility model, by setting multiple upper magnetic rods, allows the condensate to pass through the multiple upper magnetic rods sequentially after entering the iron removal box, thus effectively removing iron and ensuring the iron removal effect while preventing blockage.

[0008] 2. In this invention, before the next condensate water is introduced after iron removal from the condensate water, the upper magnetic rod can be de-energized, causing the adsorbed iron oxide particles to fall off automatically. After falling off, they will enter the chip collection hopper and then the chip collection cylinder. Then, the lower magnetic rod is energized to make it magnetic, which can adsorb the collected iron oxide particles and prevent them from being discharged with the water flow after the condensate water is introduced again.

[0010] Reference Figures 1-6 A condensate iron removal device comprises an iron removal box 2, which is an arc-shaped hollow box. Multiple upper magnetic rods 3 are fixed to the upper part of the iron removal box and are evenly distributed along the arc of the box. A chip collection hopper 4, with a conical structure, is located at the bottom of the iron removal box corresponding to the upper magnetic rods and is threadedly connected to a chip collection cylinder 5. A lower magnetic rod 7 is inserted into the chip collection cylinder. The iron removal box contains... The annular sidewall is fixed with a water collection baffle 9 for collecting water. After the upper magnetic rod is inserted into the iron removal box, it is sealed and fixed by a sealing sleeve. After the lower magnetic rod is inserted into the chip collection cylinder, it is also sealed by a sealing sleeve 10. At the same time, the chip collection cylinder is threadedly connected to the chip collection hopper, and a sealing gasket 11 is fixed inside the chip collection cylinder for sealing. Both the upper and lower magnetic rods are rod-shaped electromagnets. After being energized, they have magnetism and can attract iron oxide particles. After the power is turned off, the attracted iron oxide particles will fall under their own weight and fall into the chip collection hopper.

[0011] The water collection baffle is divided into multiple pairs, each pair is fixed inside the iron box on two arc-shaped side walls. At the same time, the water collection baffle is inclined when it is at the chip collection hopper, thus forming a water inflow channel 8. This water inflow channel will diffuse at the chip collection hopper, so that the condensed water can flow to the upper magnetic rod.

[0012] One end of the iron removal box is fixed to the water inlet pipe 1, and the other end is fixed to the water outlet pipe 6.

[0013] Working principle: During operation, the upper magnetic rod is energized. There is a distance between each pair of upper and lower magnetic rods, and the lower magnetic rod is positioned within the chip collection hopper. Condensate enters through the inlet pipe and then flows into the iron removal box. Inside the box, the water is concentrated in the water inlet channel, raising the water level. After flowing through the channel, the water diffuses to the upper magnetic rod, ensuring all the condensate reaches it and maintaining effective iron removal. After passing the first upper magnetic rod, the water continues to flow into the next water inlet channel, where it is further concentrated for iron removal, ensuring smooth water flow. After flowing out through the outlet pipe, the iron oxide particles pass through multiple iron removal stages to ensure effective removal. After iron removal, when condensate water is not introduced, the upper magnetic rod is de-energized. The iron oxide particles on the upper magnetic rod will fall off under their own weight, entering the chip collection hopper and then the chip collection cylinder. The lower magnetic rod is then energized to make it magnetic, allowing it to attract the collected iron oxide particles. When condensate water is introduced again, both the upper and lower magnetic rods are kept energized to prevent the collected iron oxide particles from being discharged with the water flow.
