Description

Comb in novel mixed bed

Technical field

This utility model belongs to water treatment field, specifically, relates to the middle row pipeline regenerating mixed bed device.

Background technology

Regeneration mixed bed device is the important component part manufacturing high purity water equipment.Regeneration mixed bed principle is the characteristic of the selectivity exchange utilizing ion exchange resin can carry out water intermediate ion in certain sequence, during normal work, free ion in water is swapped absorption, after exchange adsorption is saturated, utilizes high concentration acid-base pair resin to regenerate.Yin and yang resin owing to being loaded in regeneration mixed bed needs to regenerate with alkali and acid respectively, therefore need to be layered yin and yang resin during mixed bed regeneration, and negative resin density is less is placed in top, and positive resin density is relatively big, placed below.Regeneration positive resin time, for avoiding negative resin contaminated, regeneration liquid waste need to from be positioned at yin and yang resin intersection middle comb discharge, this just require middle comb can proper drainage, leakage resin can not be run again, the most also need acid-alkali-corrosive-resisting.

In tradition, row is the form being cladded with filter screen with how empty 316 stainless steel tubes, although this middle discharge pipe can use, but along with mixed bed uses the increase of time, the easy aging breakage of bandage of filter screen and fixing filter screen, cause resin to be run situation leakage by middle row to occur, cause the maintenance of equipment cycle shorter, even make equipment cannot regenerative operation, this situation had a strong impact on system run security reliability.

Utility model content

Therefore, for above-mentioned problem, the utility model proposes comb in a kind of novel mixed bed, existing middle row's structure is improved, prevent middle row from running the generation of Lou phenomenon, improve the security reliability that system is run.

In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that, comb in a kind of novel mixed bed, is vertically arranged including middle row supervisor and multiple arm, arm and middle row supervisor；Described middle row supervisor includes a straight tube, and one end of straight tube arranges flange, and the other end arranges plug；Arm is connected by bump joint and straight tube are fixing, and wherein, described arm includes support, and support is wound with some annular wrapping wires, and support width scope is 10-20mm.

It addition, have gap between adjacent annular wrapping wire, this gap width scope is 0.1-0.4mm, preferably 0.25mm.

Preferably, the thickness range of middle row supervisor and arm is 3-5mm.Preferably, the material of middle row supervisor and arm all uses SS316 to realize.

Compared with prior art, in novel mixed bed of the present utility model, comb has the advantage that and good effect:

1, middle row's equipment of the present utility model, using support and annular wrapping wire to realize arm, this arm carries out drainage by the gap of annular wrapping wire, and its lifting surface area is less, water distribution effect is more preferable than terylene set arm, can also remove the trouble often changing terylene set and bring from simultaneously；It addition, said structure also will not occur the consequences such as drainage screen is damaged, bandage is aging, thus it is effectively prevented resin and runs leakage；

2, gap and spacing to annular wrapping wire strictly control so that in wall scroll, the gap of discharge pipe is uniform, and arm becomes thinner, thus are not only greatly saved material, moreover it is possible to realize preferably drainability；

3 it addition, use support and annular wrapping wire to realize arm, and this kind of structure has the advantage of simple in construction, and it also greatly strengthen the intensity of whole pipeline simultaneously.

To sum up, this utility model simple in construction, it is easy to accomplish and promote, there is good practicality.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of old-fashioned middle row of the prior art；

Fig. 2 is the schematic diagram of old-fashioned arm of the prior art；

Fig. 3 is the schematic diagram of comb in novel mixed bed of the present utility model；

Fig. 4 is the schematic diagram of arm of the present utility model.

Detailed description of the invention

In conjunction with the drawings and specific embodiments, this utility model is further illustrated.

Seeing Fig. 1 and Fig. 2, old-fashioned middle package of the prior art includes female pipe 1 and arm 2, and the arm 2 that it uses is as in figure 2 it is shown, be typically all and realized by antipriming pipe, and under this kind of mode, all of arm is required to be cladded with drainage screen completely and strictly fix.This arm is relatively big by volume after terylene set wrapping, easy season cracking and cause middle row to leak resin, the maintenance of equipment cycle that used terylene overlaps arm is shorter.Germany, Japan successively have employed cannula type arm in recent years, and it makes whole intermediate drain installation be positioned at packed resin layer top.Thus avoid the excessive adverse effect that intermediate drain installation is caused of packed resin layer pressure reduction.Owing to cannula type arm distribution performance is poor, therefore can not be widely used on domestic middle row.Above-mentioned situation is improved by this utility model just.

As a concrete example, see Fig. 3 and Fig. 4, comb in the novel mixed bed of one of the present utility model, be vertically arranged including middle row supervisor and multiple arm 20, arm 20 and middle row supervisor；Described middle row supervisor includes a straight tube 10, and one end of straight tube 10 is provided with flange 11, and the other end arranges plug 12 to block this straight tube；Arm 20 includes bump joint 21, pipe plug 22 and the second straight tube 23, one end mounting flange joint 21 of the second straight tube 23, and the other end is blocked by a pipe plug；Arm 20 is fixed by the straight tube 10 that bump joint 21 is responsible for middle row and is connected, and wherein, described arm 20 has a support, and support is wound with some annular wrapping wires, and support external diameter width (namely diametral distance of annular wrapping wire) is 10-20mm；Having gap (namely spacing of adjacent annular wrapping wire) between adjacent annular wrapping wire, this gap width is 0.1-0.4mm, and in the present embodiment, its gap is 0.25mm.

In the present embodiment, middle discharge pipe material is SS316 rustless steel, and the thickness of middle row supervisor and arm is 3-5mm.

During the water treatment facilities of the present embodiment are specifically used, less in order to make middle row be responsible for deformation, also can use cold-drawn mode.

This utility model uses such scheme, uses support and annular wrapping wire to realize arm, it is not necessary to carry out being cladded with the work such as drainage screen again, reduce cost of labor；The advantage the most also with good looking appearance, and the consequences such as drainage screen is damaged, bandage is aging will not occur, thus be effectively prevented resin and run leakage.

Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
