Description
Technical field
The utility model belongs to water-treatment technology field, particularly carries out the high flow rate mixed bed of condensed water precision processing.
Background technology
Along with growing continuously and fast of national economy, electric utility has also obtained development at full speed.China's generating set constantly develops to high-parameters, large vol direction, so boiler is also more and more higher to the requirement of feed water quality.In order to guarantee unit safety operation, China adopts condensed water precision processing system substantially at the unit of subcritical and above parameter, to remove various impurity in the condensed water, guarantees that feed water quality meets the requirements.
In China, high flow rate mixed bed is the equipment that is widely used in the condensed water precision processing most at present.Mixing bed has its water outlet purity preferably under the normal design and running condition when the H-OH type moves, and the successful experience of ammonia periodic duty is arranged.The condensed water precision processing mixed-bed system of 300MW unit is general to adopt 2 φ 2200 cylindricalitys to mix bed, general 3 φ, the 3000 spherical beds that mix that adopt of the condensed water precision processing mixed-bed system of 600MW unit, general 4 φ, the 3000 spherical beds that mix that adopt of the condensed water precision processing mixed-bed system of 1000MW unit, every resin floor height is 1～1.2 meter, and flow velocity is at 100～120m
3/ h, separate unit is handled condensing water flow and is respectively 350～400m
3/ h and 710～848m
360 ℃ of/h design water temperatures, design pressure is about 4.0MPa.
Because the condensed water accurate process equipment is connected in the therrmodynamic system, so its running condition is directly connected to the safety of whole therrmodynamic system with reliable.Condensed water is mixed bed in service for many years, owing to the problem of the original project organization of introducing of high flow rate mixed bed influences the not within minority of the cycle of operation, and the situation that resin is escaped, resistance transfinites often takes place, cause the case of break-down maintenance to happen occasionally therefrom, become an outstanding problem that has influence on the therrmodynamic system operating safety.In Heze, Shandong power plant, because the mixed bed technique water subfill of introducing is not enough, the incident of overhauling a wheat harvesting period just took place to shut down in the reason of aspect such as last water-distributing device intensity, rigidity are low in 2002.
The utility model content
The purpose of this utility model is to provide a kind of improved high flow rate mixed bed, and to improve the cycle of operation, tightening security property reduces production costs.
High flow rate mixed bed of the present utility model is a cylindrical shell, water feed apparatus is set in the cylindrical shell from top to bottom, advances pitch tube, resin water subfill, resin layer, resin vent pipe and discharging device.
Water feed apparatus of the present utility model has been continued to use existing secondary water distribution form, the water eliminator apron ring of water through dish-shaped water eliminator and its top that enters from the top water inlet pipe carries out the one-level water distribution, porous water distribution board through band water cap carries out the secondary water distribution again, and water distribution is very even, and resin is not directly impacted in water inlet.Advance pitch tube and enter, pass water distribution board and extend on the resin layer from the cylindrical shell top.Compare with existing high flow rate mixed bed, the utility model has added wear ring at water distribution board with the place, slit of advancing pitch tube, prevents that resin from overflowing on water distribution board from the slit; In order to strengthen the bearing strength of water distribution board, some suspension rods evenly are set connect upper cover and the water distribution board that mixes bed.
Above-mentioned wear ring can be made of the semicircular ring of two band screws, also is drilled with screw on the corresponding water distribution board, and lining rubber is fixed the two by screw between wear ring and water distribution board.
Above-mentioned suspension rod can uniformly-spaced be provided with 3,4 or more groups along circumference, and one of every suspension rod is welded with a steel plate with holes, and the other end is threaded.Two shackle plates with holes of the corresponding position of every suspension rod welding on upper cover, the steel plate of the upper end of suspension rod is inserted between two shackle plates, fixes by screw bolt and nut.Be drilled with corresponding circular hole in the corresponding position of water distribution board, nut screwing clamping is passed through after inserting in the suspension rod lower end.
Further, make into for fear of the wriggling of resin that water water cap stops up, do not reduce the height of resin layer simultaneously, the extended height at mixed bed cylindrical shell middle part of the utility model than existing length 200～300mm, makes and has so just increased resin water subfill space.
Discharging device of the present utility model also is to adopt vaulted porous dish plate to twist water hat formula compared with prior art, and even water distribution avoids taking place bed bias current phenomenon, makes full use of the exchange capacity of resin, guarantees to mix the long cycle of operation of bed.Simultaneously, because vaulted plate has certain bending curvature, therefore row unloads resin is not had the dead angle, can reach resin row and unload rate more than 99.9%.The utility model further improves and is: at the thin backing plate of lower cover inner liner stainless steel, remove original stainless steel jacket head and equilibration tube, water shoot is directly linked in the Thin Stainless Steel backing plate.
The utility model is innovated at the water-distributing device of original equipment and the structure of discharging device.For water feed apparatus, reinforcing water distribution board can not solve by the thickening water distribution board, because thick water distribution board can not solve the leakage problem of water distribution board, pulling on the manufacture craft of limit of water distribution board, the bending radius of slab can not satisfy service requirements, and water distribution board with advance pitch tube junction rigidity and weaken and can only take measures aspect the sealing property of junction increasing local rigidity and increase: in addition, the fact of the resin water subfill insufficient height of the mixed bed of introducing technology can not be ignored, and increases enough resin water subfills and is very important.High flow rate mixed bed of the present utility model has been reinforced water distribution board by suspension rod, and has strengthened water distribution board and advanced sealing between pitch tube, and the resin water subfill space of having increased simultaneously keeps the resin face smooth, and guarantees the trouble free operation of condensed water.So just avoided in mixing bed operating, taking place because the resin water subfill is low excessively, and the wriggling of resin makes it water distribution water cap and stops up the danger that water distribution board falls.
For the discharging device that mixes bed, the carbon steel end socket of traditional mixed bed bottom is because can't line with rubber anticorrosion, and adopted the vaulted plate structure of two stainless steels (promptly being screwed with the vaulted porous dish plate and the vaulted stainless steel jacket head of stainless steel double speed water cap), in the long-time running of equipment, have certain UNICOM owing to the equilibration tube that is provided with for the vaulted plate structure of two stainless steels makes carbon steel and stainless steel district, may pollute in the dead band of carbon steel; In addition, the equipment wall thickness of medium-voltage equipment makes very uneconomical of two vaulted plates of stainless steel.Lower cover carbon steel lining Thin Stainless Steel backing plate of the present utility model has not only saved original stainless steel jacket head, has also significantly reduced the pollution of condensed water.
In sum, high flow rate mixed bed of the present utility model has solved existing shortcoming of mixing bed apparatus, improved the cycle of operation of condensed water greatly, it is good to have effluent quality, the advantage that the cycle of operation is long, and reduced the frequency of resin regeneration, reduced the running cost of total system, production security is improved.
