Description

Technical Field

[0001] The utility model relates to the technical field of condensate water deironing, in particular to a high-temperature purification device for deironing steam condensate water. Background Art

[0002] The thermal energy of steam consists of sensible heat and latent heat. Usually, steam equipment only uses the latent heat and a small amount of sensible heat of steam. After releasing the latent heat and a small amount of sensible heat, the steam is reduced to high-temperature condensate. Condensate is saturated high-temperature softened water, and its thermal energy value accounts for about 25% of the thermal energy value of steam. It is also clean distilled water and is suitable for reuse as boiler feed water. Iron removal is an important link in the steam condensate treatment process. The condensate recycled by some users is red or even soy sauce-colored. The main reason is that during the recycling process, the steel of the pipes and containers that the condensate contacts oxidizes and corrodes, generating iron oxide (Fe3O4, Fe2O3) particles and colloids. Since the incoming water is desalted condensate, there are few cations in the water and the electrochemical corrosion is small. The main task of condensate iron removal is to remove iron oxide particles and colloids in the water.

[0003] Existing condensate deironing devices mostly rely on high-temperature sintered ceramic filter layers for deironing. Although this method can remove iron ions to a certain extent, the pore size of the filter layer is usually set to be small to prevent iron ions from passing through. Due to the small pore size, the filter layer is prone to clogging, which in turn affects the normal operation of the entire deironing device. Therefore, the utility model proposes a high-temperature purification device for steam condensate deironing. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The following is an explanation of the preferred embodiments of the device of the utility model.

[0022] See also Figure 1-3 As shown, a high-temperature purification device for removing iron from steam condensate comprises an iron removal purification box 1, wherein the interior of the iron removal purification box 1 is provided with a filter chamber 101, a processing chamber 102 and a filter chamber 2 103 in sequence from top to bottom, and the interior of the iron removal purification box 1 is provided with a stirring assembly 2, a water inlet pipe 3 is connected to the top of one side of the iron removal purification box 1, and a water outlet pipe 4 is connected to the bottom of the other side of the iron removal purification box 1, first mounting clamps 5 are provided on both sides of the cavity wall of the filter chamber 101, a filter plate 6 is provided in the first mounting clamp 5, and the center of the filter plate 6 A through hole 7 is opened in the center, a side frame 8 is provided on the cavity wall of the processing chamber 102, an adsorbent 9 is provided on the side frame 8, second mounting clamps 10 are provided on both sides of the second filter chamber 103, and a filter screen 11 is provided in the second mounting clamp 10, wherein the filter plate 6 in the filter chamber 1 101 can perform preliminary filtration on the condensed water, remove large particles of impurities and suspended matter therein, and protect subsequent processing components from damage, and the filter screen 11 in the filter chamber 103 can filter the condensed water passing through the processing chamber again to ensure the quality of the output water.

[0023] Among them, the working principle of the adsorbent 9 is mainly to combine with iron ions through the active sites on its surface, thereby removing them from the condensed water. Specifically, the surface of the adsorbent 9 may have a certain charge or functional group, which can interact with the iron ions so that the iron ions are adsorbed on the surface of the adsorbent 9. Commonly used adsorbents 9 include activated carbon. Among them, activated carbon can adsorb organic molecules, gas molecules, metal ions, etc. on its surface or in its pores due to its high porosity and surface area. When activated carbon is used to adsorb iron, the functional groups and pore structures on its surface can chemically or physically adsorb with iron ions, thereby removing iron ions from the condensed water.

[0024] One end of the water inlet pipe 3 is connected to a first control valve 13, and the end of the first control valve 13 away from the water inlet pipe 3 is connected to a water pump 14. One end of the water outlet pipe 4 is connected to a second control valve 15. The water inlet pipe 3 is responsible for introducing the condensed water to be treated into the iron removal purification box 1. The first control valve 13 is used to control the flow rate and switch of the water inlet, and the water pump 14 provides the power required for the water inlet. The water outlet pipe 4 is responsible for discharging the treated condensed water out of the device, and the second control valve 15 is used to control the flow rate and switch of the water outlet to ensure stable water outlet.

[0025] Further, the stirring assembly 2 includes a stirring motor 201, a connecting shaft 202, a stirring sleeve 203 and a stirring rod 204. The stirring motor 201 is arranged at the top of the iron removal purification box 1. The output end of the stirring motor 201 is connected to the connecting shaft 202. The connecting shaft 202 passes through the through hole 7 to the processing chamber 102 and is sleeved with the stirring sleeve 203. A sealing ring 701 is provided along the shaft body of the connecting shaft 202 on the through hole 7. A plurality of stirring rods 204 are provided on the ring wall of the stirring sleeve 203, and the plurality of stirring rods 204 are linearly distributed along the shaft body of the stirring sleeve 203. Specifically, when the stirring motor 201 is working, the stirring motor 201 drives the rotation of the connecting shaft 202, and the connecting shaft 202 then drives the stirring sleeve 203, and the stirring rod 204 will rotate accordingly to form a vortex, thereby enhancing the mixing and contact between the condensed water and the adsorbent 9, which is beneficial to the removal of iron ions.

[0026] A heating wire 12 is provided in the stirring shaft sleeve 203 for heating the condensed water. The condensed water in the processing chamber 102 is heated by the heating wire 12. Such heating helps to increase the activity of the iron ions and enhance the adsorption effect of the subsequent adsorbent 9 on the iron ions.

[0027] When in use, first turn on the water pump 14, and introduce the evaporated condensed water to be treated into the iron removal purification box 1 through the water inlet pipe 3. The condensed water first enters the filter chamber 101, and is initially filtered through the filter plate 6 in the first mounting clamp 5 to remove large particles of impurities and suspended matter. When the condensed water passes through the filter plate 6 and enters the processing chamber 102, the stirring component 2 starts to work, and the stirring motor 201 drives the connecting shaft 202 to rotate, thereby driving the stirring shaft sleeve 203 and the stirring rod 204 to rotate to form a vortex. At the same time, the heating wire 12 in the stirring shaft sleeve 203 starts to heat up to increase the temperature of the condensed water. To enhance the activity of iron ions, in the processing chamber 102, the rotating stirring rod 204 and the heating wire 12 work together to promote the condensed water to be fully mixed and contacted with the adsorbent 9 on the side frame 8. The adsorbent 9 uses the active sites and functional groups on its surface to adsorb the iron ions in the condensed water. The condensed water passes through the processing chamber 102 and enters the filter chamber 103. It is filtered twice by the filter mesh 11 in the second mounting clamp 10 to further remove residual impurities and particulate matter. The purified condensed water is discharged from the device through the outlet pipe 4, and the outlet flow and switch are controlled by the second control valve 15.
