Abstract
The utility model particularly relates to a decolorizing old carbon recovery device in a maltitol production technology. The decolorizing old carbon recovery device comprises a decolorizing filter. The decolorizing old carbon recovery device is characterized by also comprising a settling pond, a filter press and a sewage treatment tank, wherein the decolorizing filter is connected with the settling pond through a carbon-containing water pipe; a slag pumping tube is arranged at the bottom of the settling tank; a slag pump is arranged on the slag pumping tube; the slag pumping tube is connected with a filter press; and a water outlet of the filter press is connected with the sewage treatment tank through a discharge tube. The decolorizing old carbon recovery device is simple in structure and convenient to use; and active carbon in carbon-containing washing water can be effectively recovered. By adopting the decolorizing old carbon recovery device, recovery of the old carbon in the decolorizing procedure is achieved; burden of the sewage treatment procedure is reduced; the dry old active carbon filtered by a plate-and-frame filter press is sold and great economic benefits can be brought about.
Description
Technical field
The utility model is specifically related to the old charcoal retrieving arrangement of decolouring in a kind of maltose alcohol production technique.
Background technology
Crystal maltitol is to take maltose as raw material, and hydrogenation obtains the maltose alcohol of high density, then through crystallization, drying, be packaged to be the powdery product that product forms, smell is pure, is widely used in the industries such as food, medicine, chemical industry.Bleaching process is most important in the crystal maltitol production process, material is through the decolouring of decolorization filtering machine, after gac in the decolorization filtering machine is saturated, just need to more renew charcoal, old charcoal effluxes with wash water, saturated gac effluxes with the filter wash water, has both caused the waste of old gac, brings white elephant to again the sewage disposal operation.
The utility model content
The purpose of this utility model is to solve in current maltose alcohol production, at bleaching process, after gac in the decolorization filtering machine is saturated, with wash water, efflux, both caused the waste of old gac, the defect of bringing white elephant to again the sewage disposal operation, provide a kind of simple in structure, cost is low, from wash water, old Activated carbon separation is out recycled, alleviated the old charcoal retrieving arrangement of decolouring of sewage disposal operation burden.
The utility model is achieved by the following technical solution:
It is the old charcoal retrieving arrangement of a kind of decolouring, comprise the decolorization filtering machine, it is characterized in that also being provided with settling tank, pressure filter and treatment tank, described decolorization filtering machine is connected with settling tank by carbon containing water transfer lime, described settling tank bottom is provided with dreg-drawing pipe, dreg-drawing pipe is provided with takes out pulp pump, and described dreg-drawing pipe is connected with pressure filter, and the water outlet of pressure filter is connected with treatment tank by rising pipe.
As a preferred version of the present utility model: described pressure filter is plate-and-frame filter press.
The utility model is built a settling tank near the decolorization filtering machine, at the other plate-and-frame filter press of installing of settling tank, enter settling tank containing the charcoal wash water by pipeline by what produce in production process, after precipitation, with taking out pulp pump, take out toward plate-and-frame filter press, water through press filtration is discharged into treatment tank again, and siccative is recycled (the old gac of main component).
The utlity model has simple in structure, easy to use, can efficient recovery the advantage of gac in the carbon containing wash water.The utility model has been realized the recovery of the old charcoal of bleaching process, has alleviated the burden of sewage disposal operation, filters the old gac of the siccative obtained through plate-and-frame filter press and takes out, and can bring larger economic benefit.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
As shown in the figure: 1 decolorization filtering machine; 2 containing charcoal water transfer lime; 3 settling tanks; 4 take out pulp pump; 5, dreg-drawing pipe; 6 pressure filter; 7 rising pipes; 8 treatment tanks.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1: decolorization filtering machine 1 is connected with settling tank 3 by carbon containing water transfer lime 2, the bottom of settling tank 3 is provided with dreg-drawing pipe 5, dreg-drawing pipe 5 is provided with takes out pulp pump 4, the other end of dreg-drawing pipe 5 is connected with the opening for feed of pressure filter 6, and the water outlet of pressure filter 6 is connected with treatment tank 8 by rising pipe 7.
The charcoal wash water that contains of the present utility model enters settling tank 3 by carbon containing water transfer lime 2, after precipitation, with taking out pulp pump 4, takes out toward pressure filter 6(plate and frame), be discharged into again treatment tank 8 through the water of press filtration, siccative is recycled (the old gac of main component).
Claims (2)
- One kind the decolouring old charcoal retrieving arrangement, comprise the decolorization filtering machine, it is characterized in that also being provided with settling tank, pressure filter and treatment tank, described decolorization filtering machine is connected with settling tank by carbon containing water transfer lime, described settling tank bottom is provided with dreg-drawing pipe, dreg-drawing pipe is provided with takes out pulp pump, and described dreg-drawing pipe is connected with pressure filter, and the water outlet of pressure filter is connected with treatment tank by rising pipe.
- 2. the old charcoal retrieving arrangement of decolouring according to claim 1, is characterized in that described pressure filter is plate-and-frame filter press.
