Description
Technical field
The utility model relates to high flow rate mixed bed technical field, is specifically related to a kind of reinforced two-stage high flow rate mixed bed water inlet distribution device.
Background technology
The straight side length of the domestic high flow rate mixed bed of China is lower, and hydrospace more than resin face is less, and the water flow buffer effect that can play is very limited, therefore very high to the uniformity requirements of water inlet distribution.But the water inlet distribution device of the domestic high flow rate mixed bed of China's overwhelming majority adopts baffle plate to add this form of perforated-plate-water-cap, one level water injection allocator is too simple, be only one piece of circular baffle plate perpendicular to water-in, and secondary water distribution is owing to have employed the porous plate of band water cap, be easy to the situation occurring that water cap is blocked by resin, therefore water distribution effect is difficult to ensure, and porous plate also often excessive the and problem of deformed damaged of shock resistance occurs by the impact of water cap blocking.According to incompletely statistics, adopt baffle plate to add the high flow rate mixed bed of this water inlet distribution device of perforated-plate-water-cap, about more than 80% all exists the problem that effluent quality is unstable and water production in periodic mode is lower.Show particularly outstanding in the condensed water precision processing system of this problem and ultra supercritical coal-fired unit overcritical in China, the stability of the overcritical and ultra supercritical coal-fired unit water and steam quality of remarkably influenced and precision processing performance driving economy.And in order to thoroughly address this problem, only have an approach, namely develop a kind of novel water inlet distribution device that can adapt to China's domestic high flow rate mixed bed feature, add this high flow rate mixed bed water inlet of perforated-plate-water-cap distribution device to replace baffle plate conventional at present.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of reinforced two-stage high flow rate mixed bed water inlet distribution device, to adapt to the low feature of China's domestic high flow rate mixed bed straight side length, improves the water inlet water distribution effect of high flow rate mixed bed.
For achieving the above object, the present invention adopts following technical scheme:
A kind of reinforced two-stage high flow rate mixed bed water inlet distribution device, comprise one-level water injection allocator and graduation two hydrophone, described one-level water injection allocator comprises the tube sheet 1 be communicated with successively from top to bottom, water inlet pipe 2, water tube water inlet adapter 3 and water tube 4, the surrounding of described water tube 4 has eight holes uniformly, be welded with water tube water outlet copy woods joint 5 on every hole, the long bend pipe 6 of water inlet end band copy woods joint and short bend pipe 7 distribute alternately and copy woods joint 5 with water tube water outlet and adopt clip to dock, the upper end of semi-circular tube 9 and the lower end welding of long bend pipe 6, lower end and a point water baffle plate 10 weld, the upper end of round steel 8 and the lower end welding of short bend pipe 7, lower end and a point water baffle plate 10 weld, described graduation two hydrophone comprises upper strata porous plate 11 and lower floor's porous plate 12, and described point of water baffle plate 10 is fixed on upper strata porous plate 11.
The inner-wall surface of described semi-circular tube 9 is towards the central shaft of upper strata porous plate 11 and lower floor's porous plate 12.
The upper strata porous plate 11 of described graduation two hydrophone and the diameter of lower floor's porous plate 12 be high flow rate mixed bed diameter 50% ~ 80%, thickness is 4 ~ 8mm, open pore size is 15 ~ 32mm, pitch-row is 15 ~ 50mm, the perforate of upper strata porous plate 11 and lower floor's porous plate 12 overlaps.
Described upper strata porous plate 11 and lower floor's porous plate 12 are cut into four pieces respectively, and cutting angle is different, and the line of cut direction of formation is different, and after two boards overlap is installed, line of cut interlocks.
One end of described water inlet pipe 2 is with outside screw, and the other end welds with tube sheet 1; Internal thread is with in water tube water inlet adapter 3, docks with the outside screw of water inlet pipe 2, and water tube water inlet adapter 3 is welded with between water tube 4.
A bolt hole is opened at the center of described baffle plate 10, and periphery symmetry opens three bolts hole, upper strata porous plate 11 and point with bolts between water baffle plate 10 and lower floor's porous plate 12.
Compared to the prior art, tool has the following advantages in the present invention:
1) radiation that, the one-level water distribution of reinforced two-stage high flow rate mixed bed water inlet distribution device adopts water tube to guide is propped up form of tubes and is guided formula distribution, baffle plate is adopted to carry out natural style distribution compared to existing technology, distribution effects is better, and resistance to overload shock ability is strong.
2), the graduation two hydromining diameter of reinforced two-stage high flow rate mixed bed water inlet distribution device is less than the porous plate of high flow rate mixed bed diameter, and therefore porous plate edge does not suit with high flow rate mixed bed inwall, and porous plate and high flow rate mixed bed inwall exist certain gap.When high flow rate mixed bed is exerted oneself excessive, this gap can play fully to be shunted and prevents the distortion that porous plate aperture flow velocity is too high, resistance is excessive and cause, and makes high flow rate mixed bed water inlet distribute more even simultaneously.The diameter adopted compared to existing technology is equal to the porous plate of high flow rate mixed bed diameter, and its anti-load impact ability is stronger, porous plate not easily unbalance stress and being out of shape.
3), the porous plate that adopts of reinforced two-stage high flow rate mixed bed water inlet distribution device, the diameter, position of opening, the number of openings, aperture, pitch-row etc. of upper strata porous plate and lower floor's porous plate are completely the same.Its percentage of open area, opening diameter and perforate spacing etc. determine after repetition test, the perforated-plate-water-cap adopted compared to existing technology, the water-flow equation situation that its aperture is derived and flow rate of water flow more can adapt to the lower water subfill of domestic high flow rate mixed bed (allowing high flow rate mixed bed water subfill to be low to moderate 500mm), water distribution better effects if.
4) porous plate that, reinforced two-stage high flow rate mixed bed water inlet distribution device adopts is double-layer porous plate, the cutting gap of upper strata porous plate is covered by lower floor's porous plate, and the cutting gap of lower floor's porous plate is covered by upper strata porous plate, namely the cutting gap of porous plate is staggered covering, current can not pass porous plate gap, cause current disorderly.And the single perforated plate that prior art adopts, its cutting gap is passed by current, is in operation to increase gradually by the impact of flow resistance, reaches 5 ~ 10mm, cause obvious bias current time larger.
5), in general, reinforced two-stage high flow rate mixed bed water inlet distribution device compared with prior art, more suitable for the domestic high flow rate mixed bed of China, also can be used for into the import high flow rate mixed bed that water distribution device is too simple or distribution effects is poor, can effectively prevent high flow rate mixed bed from running bias current, make the effluent quality of high flow rate mixed bed keep stable, and enlarge markedly the water production in periodic mode of high flow rate mixed bed.
