Abstract

The invention aims to provide an active carbon pickling tank, which has the characteristics of difficulty in damaging a pv (polyvinyl) plastic barrel, smooth flow of liquid during liquid discharge and effective prevention of active carbon from flowing out along with the liquid after pickling. In the invention, the active carbon pickling tank comprises a barrel of which the bottom is provided with a liquid outlet, wherein the inner lower part of the barrel is provided with a filter plate which is provided with filter holes; the upper surface of the filter plate is provided with a filter layer formed by paving refractory bricks; an isolation frame is arranged below the filter plate, and comprises more than three spoke plates extending along the radial direction of the barrel; the barrel is made of pv plastic; the outer side of the barrel is provided with an annular wall built by using refractory bricks and acid-proof cement around the barrel; and a gap is formed between the inner wall of the annular wall and the outer wall of the barrel.

Description

The gac pickling tub that a kind of gac runs off less, fluid is rapid, the life-span is long

Technical field

Present technique relates to a kind of gac pickling tub.

Background technology

Existing gac pickling tub comprises that a bottom has the cylindrical shell of liquid outlet, and the cylindrical shell inner bottom part is provided with the screen plate that has filter opening.During pickling, reacting in material (gac, hydrochloric acid etc.) the adding cylindrical shell, the reaction back bleeds off liquid through liquid outlet.

There is following problem in existing gac pickling tub.When fluid,, let tiny activated carbon granule flow out with liquid through filter opening though the filtration of screen plate is arranged.In addition, because not to the heating unit of material, material reaction is slower, long reaction time.And because screen plate contacts with the inner bottom part of cylindrical shell, when fluid, liquid is difficult to flow out through filter opening, liquid outlet.Though the cylindrical shell of the pickling tub that has is processed with the pv plastics of acid-fast alkali-proof, and the annular walls that is built into refractory brick and acid-proof cement around cylindrical shell is arranged in the arranged outside of cylindrical shell; But since very close to each other between annular walls inwall and the cylinder body outer wall, and the pv plastics expand with heat and contract with cold easily, cause the pv plastic cylinder fragile.

Summary of the invention

The purpose of present technique provides that a kind of pv plastic cylinder is not fragile, liquid-flow is unobstructed during fluid prevents that effectively gac after the pickling is with the effusive gac pickling tub of liquid.

The gac pickling tub that this is technological comprises that a bottom has the cylindrical shell of liquid outlet, and the bottom is provided with the screen plate that has filter opening in cylindrical shell, on the upper surface of screen plate, has with refractory brick to mat formation into a filtering layer; The below of screen plate has shelf, and said shelf comprises the spoke slat that radially extends of three above upper edge cylindrical shells; Said cylindrical shell is processed with the pv plastics, in the arranged outside of cylindrical shell the annular walls that is built into refractory brick and acid-proof cement around cylindrical shell is arranged; Gapped between annular walls inwall and the cylinder body outer wall.

The beneficial effect of present technique: owing to have a filtering layer of forming with refractory brick; The gap that has nature between each refractory brick; Add the gap between refractory brick and the screen plate, these gaps have stopped that gac directly flows out through filter opening, that is to say; Filtering layer and screen plate have played filteration to gac jointly, have effectively prevented the outflow of gac.Shelf separates screen plate and cylindrical shell inner bottom part, the resistance when reducing fluid to liquid, and the passage when liquid flows out is more unobstructed.Said gap is that expanding with heat and contract with cold of cylindrical shell reserved extendable room, prevents that cylindrical shell from damaging long service life.Present technique is the gac pickling tub that a kind of gac runs off less, fluid is rapid, the life-span is long.

Above-mentioned gac pickling tub has plural hole on spoke slat, the spiral steam heating tube that communicates with vapour source passes described hole; Has the air outlet on the steam heating tube.In cylindrical shell, feed steam through steam heating tube, material is heated, accelerated speed of response.For homogeneous heating, the steam heating tube helically.Best, have a plurality of air outlets that cylindrical shell week makes progress that are distributed on the steam heating tube.Like this, because the shelf protection is arranged, steam heating tube can prevent to be filtered the plate flattening and be out of shape, and spiral steam heating tube can not counteract the outflow of liquid basically yet.

Above-mentioned gac pickling tub is provided with the heat insulating layer at the annular walls inwall.

Embodiment

Referring to Fig. 1, the gac pickling tub shown in 2, comprise that a bottom has the cylindrical shell of processing with the pv plastics 1 of liquid outlet 11, has filtering layer 2, screen plate 3, dividing plate 4 (comprising steam heating tube 5) from the top down successively in cylindrical shell.In the arranged outside of cylindrical shell the annular walls 6 that is built into refractory brick and acid-proof cement around cylindrical shell is arranged; Between annular walls inwall and the cylinder body outer wall gapped 7.Be provided with heat insulating layer 8 at the annular walls inwall.

Referring to filtering layer shown in Figure 32, it is mated formation by polylith standard refractory brick 21 naturally, has the gap between each refractory brick.The bottom of filtering layer 2 is screen plates 3.

Referring to screen plate shown in Figure 43, have filter opening 31 on it.

Shown in Fig. 1,2,5-7, dividing plate 4 is positioned at the below of screen plate, directly contacts with the inner bottom part of cylindrical shell.Shelf comprises the spoke slat 41 that radially extends along cylindrical shell of four cruciform shape.On each spoke slat, have plural hole 42.The spiral steam heating tube that communicates with vapour source passes described hole 42.

Referring to the steam heating tube 5 shown in Fig. 5-7, have a plurality of air outlets 51 that make progress in cylindrical shell week that are distributed on it.
