Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, and particularly relates to a kind of furfuryl alcohol production wastewater treatment device. BACKGROUND

[0002] Sugar alcohol production is mostly with glucose, xylose and other sugars as raw materials, which will produce incompletely reacted raw materials, byproducts and catalyst residues in the links of hydrolysis, hydrogenation, fermentation and the like, forming high-concentration organic wastewater. In addition, if furfuryl alcohol wastewater is mixed with high-hardness wastewater in the production process, such as boiler drainage or cooling water, although the low-concentration wastewater such as condensate water and cooling water in sugar alcohol production has less pollutants, the water volume is large, and long-term accumulation will still bring environmental load, so a softening treatment step needs to be added when treating such wastewater, that is, auxiliary softening is carried out by ion exchange resin or chemical precipitation method.

[0003] In the process of wastewater softening treatment, resin and brine jointly act on the hardness ions in wastewater to soften water quality. The resin can adsorb calcium, magnesium and other hardness ions in water, and exchange sodium ions on the resin with calcium and magnesium ions in wastewater by ion exchange, so as to reduce the hardness of water and obtain soft water. The resin can also remove heavy metal ions and organic substances in water to further soften water quality. In addition, brine is mainly used for resin regeneration in the process of softening water. When the resin adsorbs a certain amount of calcium and magnesium ions, its exchange capacity will be weakened. The sodium ions in the brine can replace the adsorbed calcium and magnesium ions on the resin, so as to restore the exchange capacity of the resin and enable it to continue to soften water quality.

[0004] The patent document with publication number CN118724174B discloses a softening water treatment equipment, which comprises a filter box body, a raw water outlet pipe is arranged at the upper end of the filter box body, a water inlet is formed at the top of the filter box body, a filter cleaning mechanism is arranged on the surface of the water inlet, a valve device is rotatably connected in the raw water outlet pipe, a support frame is fixedly connected to the surface of the filter box body, a driving mechanism is fixedly connected in the support frame, a synchronous mechanism is fixedly connected to the surface of the filter box body, a filler mechanism is arranged on the side surface of the synchronous mechanism, and an ion exchange resin filter screen is fixedly connected in the filter box body. The filler mechanism comprises a brine tank, and the brine in the brine tank is introduced into the resin to restore the softening function of the resin.

[0005] However, the following problems still exist in the scheme. The resin close to the raw water inlet is more likely to reach saturation, while the resin particles far from the inlet are not saturated. If the whole resin is regenerated, the unsaturated resin will not be fully utilized. If the regeneration is performed after all the resin reaches saturation, the softening effect of the raw water will decrease with the increase of the saturation degree of the resin. SUMMARY

The regenerated resin is transported back to the reaction assembly 2 through the guide assembly 4 again, so as to treat the furfuryl alcohol wastewater again.

[0048] At the same time, when the furfuryl alcohol wastewater is softened and the resin is regenerated, the resin is extruded by the extrusion assembly 5, the gap between the resins is adjusted, and the reaction of the resin with the furfuryl alcohol wastewater or the salt water is more sufficient, so as to improve the regeneration effect of the resin and the softening effect of the furfuryl alcohol wastewater.

[0049] Referring to Figures 2 to 6 The reaction assembly 2 includes a bottom plate 21 and a top plate 22, and the bottom plate 21 and the top plate 22 are arranged in a vertical direction in the tank 1. The top plate 22 is arranged on the side of the bottom plate 21 close to the inlet 11, and the side surfaces of the bottom plate 21 and the top plate 22 are respectively connected with the inside of the tank 1.

[0052] Referring toFigure 5 The driving component 54 drives the transmission rod 53 to rotate reciprocally. The rotation of the transmission rod 53 drives the extrusion plate 51 to rotate reciprocally. The two spiral spaces of the extrusion plate 51 rotate, increasing and decreasing repeatedly, while simultaneously extruding the resin filled inside. This ensures that the resin in the reaction chamber reacts fully with the furfuryl alcohol wastewater, resulting in a more uniform overall reaction. Multiple protrusions 511 are provided on the outer side of the extrusion plate 51. When the extrusion plate 51 rotates, the protrusions 511 enhance the extrusion effect on the resin, making the resin more uniform.

One end of the transmission rod 53, away from the bottom plate 21, passes through the regeneration assembly 3 and extends to the outlet 13. An opening 531 is provided at the end of the transmission rod 53 near the outlet 13. An intermediate tube 6 is installed inside the transmission rod 53, with a gap between the intermediate tube 6 and the inner wall of the transmission rod 53.

[0056] Reference Figures 2 to 6 The regeneration component 3 includes a second bottom plate 31 and a second top plate 32. The second bottom plate 31 and the second top plate 32 are arranged at intervals in the vertical direction of the tank body 1, that is, the arrangement of the second bottom plate 31 and the second top plate 32 is the same as the arrangement direction of the first bottom plate 21 and the first top plate 22.

The second top plate 32 is located on the side of the second bottom plate 31 close to the first bottom plate 21, and a through hole 321 is opened on the second top plate 32.

[0057] Reference Figures 2 to 6 In addition, in this embodiment, the bottom plate 31 is set as a filter plate with multiple holes to filter the brine in the resin, so that the brine enters the tank 1 after reacting with the resin.

[0058] With reference to Figure 1 The sealing plate 141 is arranged on the side of the bottom plate 2 31 away from the top plate 2 32, the transmission rod 53 penetrates the sealing plate 141, and the outlet 2 14 is arranged between the sealing plate 141 and the bottom plate 2 31. The salt water enters the space between the sealing plate 141 and the bottom plate 2 31 through the bottom plate 2 31, and then flows out through the outlet 2 14.

[0059] The guiding assembly 4 guides the resin into the regeneration cavity, the salt water enters the tank 1 through the inlet 2 12, and then enters the regeneration cavity through the through hole 2 321. The resin in the regeneration cavity is regenerated, and then enters the space between the baffle and the bottom plate 2 31 through the bottom plate 2 31 after the treatment is completed, and then is discharged through the outlet 2 14.

In the process of repeated extrusion, the contact pressure between the resin particles is repeatedly increased, so that the impurities on the surface of the resin particles are rubbed off, and the resin particles are further rubbed and washed uniformly, so that the salt water and the furfuryl alcohol wastewater are fully reacted. In addition, when the distance between the spiral fins 422 is increased, the resin particles become loose, so that the impurities are removed.

Further, the resin is gradually transported by the two rubber parts 8. At the same time, under the action of the conveying part 42, the regenerated resin is continuously transported into the reaction cavity, so that the extrusion plate one 51 extrudes the resin into the guide pipe 41.

[0070] The implementation principle of the present application is that when the sugar alcohol wastewater is softened, the specific steps are as follows: the furfuryl alcohol wastewater is introduced into the reaction cavity through the inlet one 11 and the through hole one 221, and the furfuryl alcohol wastewater is introduced into the reaction cavity and reacts with the resin; then the furfuryl alcohol wastewater is introduced into the transmission rod 53 between the through hole 532 and the intermediate pipe 6 after reaction, and finally is discharged through the outlet one 13; then the driving part 54 drives the extrusion plate one 51 and the extrusion plate three 55 to rotate, drives the resin in the reaction cavity to enter the regeneration cavity through the guide pipe 41; then the salt water is introduced into the regeneration cavity and reacts with the resin, and the reacted resin is introduced into the intermediate pipe 6 through the conveying inlet 61; finally, the power part 421 drives the spiral blade 422 to rotate, and the resin is conveyed into the reaction cavity.

[0071] When the resin is softened in the reaction cavity and regenerated in the regeneration cavity, the driving part 54 drives the extrusion plate one 51 and the extrusion plate three 55 to rotate, the size of the spiral cavity in the reaction cavity and the regeneration cavity is adjusted reciprocatingly, and then the resin is repeatedly extruded, so that the resin and the furfuryl alcohol wastewater can fully react, and the salt water and the resin can fully react. So that when the resin is regenerated, the resin can be fully utilized, and the effect of softening the furfuryl alcohol wastewater by the resin is improved.
