Summary of the invention

The purpose of this utility model is to provide the boiling and the interior electrolysis wastewater handler of fixed dual-purpose bed of electrolytic reaction mode in a kind of fluidization.

The purpose of this utility model is achieved in that this handler is to be provided with the handler body (1) that into water and inlet mouth, upper end is provided with water outlet by the bottom to be main body, the distribute water and air layer is equipped with in bottom in handler body (1), constitute the boiling reaction chamber by filler (7) and expansion space (2) on it, a porous plate (3) is assembled at the top of expansion space (2), and porous plate (3) is gone up uniform hanging the impacting stick (4) that places in the boiling reaction chamber.

Be provided with 2-4 boiling reaction chamber that is interconnected in the waste waster processor body (1) successively, separate by porous plate (3) and bed course (6) between two boiling reaction chambers.

The water outlet place of handler body (1) is equipped with magnetic screen (8).

Described distribute water and air layer is made up of gas distribution pipe (9), porous plate (3), bed course (6), and gas distribution pipe (9), porous plate (3) and bed course (6) are assemblied in the bottom of handler body (1) successively.The distribute water and air layer also can be a distribute water and air filter.

The technical progress that the utility model is obtained: under water inlet power and compressed-air actuated effect, can make packing layer in the boiling reaction chamber, be the fluidization zeiosis, add the swing of material loading impacting stick, make filler in three-dimensional space, obtain sufficient movement and friction.Thereby the bed of material is constantly in time purified, make filling surface remain cleaning, be in activatory optimum response state.In order to save power, to compress empty annoying discontinuous and supply with, the motion that filler causes when air feed not is very little, and can proximately see " fixed bed " this moment as.Though so the power that consumes is very little, it improves 3-6 doubly than the speed of response of simple fixed bed, this equipment volume is little simultaneously, energy consumption is low.Not only reduce the cost investment, also reduced working cost.It is the renewal product of present similar fixed bed treatment facility.

Description of drawings

Be that embodiment further specifies the utility model below with the accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is another embodiment of the present utility model.

Fig. 3 is the third embodiment of the present utility model.

Embodiment

As shown in Figure 1, the profile of this handler body (1) is a round filter columnar structure, and its underpart is provided with water-in (5) and inlet mouth, upper end are provided with water outlet.The distribute water and air layer is equipped with in bottom in the handler body (1), and described distribute water and air layer is made up of gas distribution pipe (9), porous plate (3), bed course (6), and gas distribution pipe (9), porous plate (3) and bed course (6) are assemblied in the bottom of handler body (1) successively.The distribute water and air layer also can be a distribute water and air filter or porous web plate.Constitute the boiling reaction chamber by filler (7) and expansion space (2) on the bed course (6), a porous plate (3) is assembled at the top of expansion space (2), and porous plate (3) is gone up uniform hanging the impacting stick (4) that places in the boiling reaction chamber.Bed course (6) reduces the bigger acid and alkali-resistance material of proportion gradually by water inlet direction particle diameter such as the arrangement of quartzite class material constitutes, filler (7) selects particle diameter less than bed course (6), by mixing material different-grain diameter and ratio and that can use as electrolysis positive and negative electrode in the microbattery, filler (7) is unsuitable blocked up.Be expansion space (2) on the filler (7), a porous plate (3) is assembled at the top of expansion space (2).It both can prevent the loss of filler (7), and porous plate (3) plays good percussion effect when filler (7) seethes with excitement.Be adsorbed in the more effective disengaging of the lip-deep settling of filler (7) in order to make, going up uniform hanging at porous plate (3) has the impacting stick (4) that places in expansion space (2) and the packing layer (7).The layout density of impacting stick (4) can suitably be adjusted according to practical situation.Convenient in order to fill out discharging simultaneously, the charging opening (11) and the discharge opening (manhole) (10) that are communicated with the boiling reaction chamber are housed respectively on the outer wall of expansion space (2).

This handler is generally continuously-running duty, and in order to guarantee the effective reaction times, its packing layer needs suitable thickness.Can impel filler-reinforced motion by recoil gas distribution pipe (9) input pressurized air.Be assemblied in the preceding magnetic screen (8) of water outlet and can prevent effectively that the iron powder in the filler is flushed away loss.

In order to improve the processing efficiency of waste water.Reduce floor space, can be designed to the boiling reaction chamber that multilayer is interconnected in the electrolysis treatment machine in this type of, between two boiling reaction chambers, separate by porous plate (3) and bed course (6).Generally be designed to layer 2-4, provided the structural representation of 2 layers and 3 layers as Fig. 2 and Fig. 3 respectively.When equipment was too high, middle sectional connected with flange.This kind structure not only can make waste water that the sufficient reaction times is arranged in the boiling reaction chamber, also effectively improves the collision opportunity of filler.

When this handler uses, waste water enters expansion space (2) through porous plate (3), bed course (6) and filler (7) from bottom to top by water-in (5), under waste water flow velocity and pressure and compressed-air actuated effect (in order to save power, pressurized air can discontinuous be regularly supplied with) make filler be in fluidization boiling shape to seethe.Its resultant is attached to the solid surface of filler.Because filler buoyancy and particle diameter, proportion are less, can only be soft contact between the material grain.But under doing of impacting stick (4) and porous plate (3) used, filler produced the percussion friction, and the settling of filling surface is broken away from, and took away with current.

Because this handler can obtain regeneration, purify in the filler use, packing specific area is very big in addition, thereby processing efficiency improves greatly, the electroplating wastewater that contains Cr with processing is an example, when former water from 50mg/l reduce to discharging standards (＜0.5mg/l), handle with the iron filings fixed beds, reaction times is about 20-40 minute, but under this appointed condition, only can finish, raise the efficiency 3-6 times more than, and effect stability be reliable with 6-10 minute.
