Abstract
The utility model relates to a slag water cooler used for dust removal in a power plant, which adopts a shell-and-tube type structure. The utility model is characterized in that a flow baffle plate dividing a shell body into two bodies is axially arranged in a cylindrical shell, and the side of the shell is provided with a deflecting plate. Slag water flowing through a tube bundle and cooling water flowing between every two tubes are two counter-current flowing flows. Two to five coolers are in series connection to form a multi-layer composite structure. A cooling water inlet and a cooling water outlet and a slag water inlet and a slag water outlet of the composite cooler are distributed at the same side of the cooler. The structure is suitable for adopting the tube bundle with a large caliber, which can prevent suspended substances of slag water from clogging a pipeline, so the reliability is high. The multi-layer composite structure of the cooler has the advantages of high heat transfer efficiency, good cooling effect and convenient installation and maintenance. The utility model is a novel slag water heat exchanger.
Description
Technical field
The utility model relates to shell and tube exchanger, particularly is used to cool off the heat exchanger of pulp water in thermal power plant's pulp water closed circulation system.
Background technology
The boiler of steam power plant adopts waterpower to slag tap more at present.After lime-ash falls into slag notch, utilize water under high pressure to go out, after heavy ash, clarification and cooling, recycle.The pulp water closed circulation system adopts plate type heat exchanger more at present, and through-flow gap is less, easily stops up, and inter deterioration is big, and fault is many, and maintenance is inconvenient, and heat exchange and result of use are poor.
Summary of the invention
The purpose of this utility model is to avoid the above-mentioned deficiency of prior art, provides that a kind of heat-transfer effect is good, reliable operation, pulp water cooler easy to maintenance.
Solution of the present utility model is: adopt the shell-tube type structure, comprise cylindrical housing, heating surface bank, front and rear cover and spoiler etc., it is characterized in that being provided with vertically in each cylindrical housing inside the cutoff board that housing is divided into two; At shell-side spoiler is housed; In one side end cap diaphragm is set; The pulp water and the cooling water between flowing pipe of restraining of flowing through is adverse current two flow processs; Form the multiple layer combination structure by 2～5 above-mentioned cooler series connection.
The multiple layer combination structure that above-mentioned 2～5 coolers series connection forms into and out of cooling nozzle and be arranged in the same side of cooler into and out of the pulp water mouth.
The heating surface bank of above-mentioned pulp water cooler can adopt copper pipe, stainless steel tube, titanium pipe or carbon steel pipe etc.
The utility model compared with prior art has following advantage:
1, adopts multi-layer combined type structure, good cooling results, heat transfer efficiency height.
2, be fit to adopt the larger caliber tube bank, be difficult for stopping up the reliability height.Straight pipeline is adopted in tube bank in each cooler, and two ends are adopted and separated end cap, is convenient to cleaning tube bank scaling inside or accumulated slag.Be convenient to installation and maintenance.
3, simple in structure, cost is low, and floor space is little.
4, by adjusting the housing size and the internal structure of cooler, adapt to different pulp water closed circulation systems.
5, the different materials of employing such as cooling tube bundle, housing, end plate can adapt to different heat-exchange systems.
Description of drawings
Accompanying drawing is the overall structure schematic diagram of this pulp water cooler.
The specific embodiment
Referring to accompanying drawing, each cooler is made up of cylindrical housing 1, heating surface bank 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5 etc.Pulp water flows in heat-transfer pipe, and cooling water flows outside pipe, and the two is separated by heating surface bank.By cutoff board 6 separately, form and come and go two flow processs in the middle of each cooler,, thereby improve heat exchange efficiency with the flow process and the flow velocity of increase cooler.Heating surface bank comes and goes two flow processs also corresponding being divided into.This combined type pulp water cooler is made up of a plurality of independent coolers.As figure, cooling water is entered by combined cooler upper orifice 7, in the heating surface bank flows outside, under the effect of spoiler 5, increases the heat exchange efficiency of cooling water.Behind first heat exchanger, enter second, third heat exchanger successively through communicating pipe 8,9 again, the lower nozzle 10 by heat exchanger flows out at last, absorbs the pulp water heat, realizes the endothermic effect of system requirements.Pulp water is entered by the lower nozzle 11 of combined cooler, flows in cooling tube bundle.Between adjacent two cooler ends connecting pipe 14 is arranged, pulp water is imported next cooler, the rest may be inferred.Diaphragm 13 is all arranged in the drive end bearing bracket, make pulp water can come diffraction current.Pulp water is discharged by the upper orifice 12 of combined cooler, after the water that is cooled absorbs heat, reaches the effect of pulp water heat release.This cooler adopts reverse heat-exchange, can make the pulp water outlet temperature reach minimum, realizes best heat exchange efficiency.
For avoiding stopping up, the bore of heating surface bank can select greatlyyer in this cooler.Cooling water inflow is determined by cooler casing caliber, internal pipeline quantity, to satisfy the needs of various different pulp water cooling systems.Between Dn150～Dn650, inner cooling pipe diameter is between Dn5～Dn50 usually for the diameter of the housing of this kind pulp water cooler, and the unit of adaptation is 6MW～12000MW.Specifically remove needing design, calculating relevant parameter of slag system according to power plant, in case typing is made, operation parameter is just definite.This cooler belongs to initiative at the pulp water cooling system, is a kind of pulp water cooler of brand-new structure.
