Abstract

An efficient wave-surface plate type coal economizer is mainly characterized in that wave surface plates are arranged inside the casing of the coal economizer, wherein two connecting pipes communicated with the hollow casing are arranged on each wave surface plate, the wave surface plates parallel to one another form wave surface plate ranks, the two connecting pipes in each rank of the wave surface plate are respectively connected with a water side inlet and a water side outlet, the wave surface plate ranks are fixed inside the casing through connecting parts, and the wave surface plate faces are basically parallel to the flue gas flowing direction. In the utility model, the eat exchange area distributed in a unit volume is increased greatly, the heat exchange efficiency of the coal economizer is improved, the probability of dust stratification on the wave surface plates is low, the slab of the wave surface plate is formed by processing stainless steel material, the probability of corrosion is low, and the operation is safe and reliable.

Description

The board-like economizer in efficient corrugated
Technical field
The utility model relates to a kind of heat exchanger.
Background technology
At present, economizer is widely used in all trades and professions tail flue gas waste heat recovery apparatus, and its structure is mainly coiled, and its weak point is: the heat exchange area of 1, in housing, arranging is less, and the coefficient of heat transfer is low, and equipment volume is big, and weight is heavier; 2, general snakelike heat exchange tube outer surface all is provided with the fin that increases heat exchange area, and dust stratification causes heat exchange efficiency low easily; 3, the coil pipe type economizer is generally ordinary carbon steel at present, corrodes easily, as adopts etch-proof stainless steel, can be big because of equipment volume, and make cost too high.
Summary of the invention
The purpose of the utility model is to provide a kind of heat exchange efficiency height, long service life, simple in structure, the board-like economizer in efficient corrugated that resistance to corrosion is strong.The utility model mainly is the coiled pipe that is replaced existing economizer by corrugated plate row.The utility model mainly includes housing, smoke entrance pipe, corrugated plate row and water import and export collection case.Wherein, side's tube that the economizer housing is made up of shaped steel and shell plates is respectively equipped with flue gas import and export pipe on its openings at two ends.In above-mentioned economizer housing, be provided with the corrugated plate; This every corrugated plate is by two well-regulated grooves and the hollow housing formed of the thin plate sheet of die mould all around; Be equipped with two adapters that are connected with hollow housing on each corrugated plate; The above-mentioned corrugated plate that several are parallel to each other constitutes corrugated plate row, and two adapters of every row corrugated plate link to each other with water side import and export collection case respectively.As required; Above-mentioned corrugated plate is plate face arranged side by side some in plane that coexist preferably; Adapter on adjacent two corrugated plates is connected by elbow, and with the series connection of water wing passage, two remaining adapters of every row corrugated plate then link to each other with water side import and export collection case respectively.Above-mentioned corrugated plate row be fixed in the housing by connector, and the ripple panel surface is substantially parallel with the flow of flue gas direction.
The utility model is when work, and water flows in the passage that is become by corrugated plate, adapter and import and export collection box-shaped, and flue gas then circulates at the passage of housing and flue gas import and export pipe composition.Plate exclusive flue gas in corrugated passes through the corrugated plate with the water in the plate of heat transferred corrugated, and water is heated after absorbing heat, and discharge from exhanst gas outlet flue gas heat release cooling back.Because heat-transfer surface has adopted the corrugated plate, the heat exchange area of in unit volume, arranging improves greatly; Corrugated plate plate is very thin, and plate inside and outside groove in corrugated makes medium just can reach turbulent flow at lower flow velocity, has improved the heat exchanger coefficient of heat collector, has improved the heat exchanger efficiency of heat exchanger so greatly; Spacing between corrugated plate and the corrugated plate is a rectangular channel, is difficult for dust stratification; Corrugated plate plate material sheet adopts stainless steel to process, and difficult the corrosion is safe and reliable to operation.
The utility model compared with prior art has following advantage:
1, arranges in the utility model unit volume that heat-transfer surface is big.
2, the plate of the utility model corrugated plate is very thin, and fluted in the plate of corrugated, and medium very low flow velocity inside and outside plate just can reach turbulent flow, and heat exchange efficiency is high.
3, weld seam is few, safe and reliable to operation on the utility model heat-transfer surface.
4, the utility model can free wxpansion, solves the thermal expansion between heat-transfer surface and the housing.
5, the utility model is difficult for dust stratification, anticorrosion.
6, device structure is simple, difficulty of processing is little, and heat exchange efficiency is high, low cost of manufacture.
Description of drawings:
Fig. 1 is that the master of the utility model looks the section simplified schematic diagram.
Fig. 2 is the utility model corrugated plate row's an amplification simplified schematic diagram.
The specific embodiment: the master at the board-like economizer in efficient corrugated shown in Figure 1 looks in the section simplified schematic diagram, and side's tube that economizer housing 1 is made up of shaped steel and shell plates is respectively equipped with flue gas import and export pipe 2,3 on its openings at two ends.In above-mentioned economizer housing, be provided with corrugated plate 4; This every corrugated plate is by two well-regulated grooves and the hollow housing formed of the thin plate sheet of die mould all around; Be equipped with two adapters that are connected with hollow housing 5 on each corrugated plate; The above-mentioned corrugated plate that several are parallel to each other constitutes corrugated plate row, and two adapters of every row corrugated plate link to each other with water side import and export collection case 6,7 respectively.Above-mentioned corrugated plate is plate face arranged side by side two in plane that coexist, and the adapter on adjacent two corrugated plates is connected by elbow 8, and two remaining adapters of every row corrugated plate then link to each other with water side import and export collection case respectively, and are as shown in Figure 2.Above-mentioned corrugated plate row be fixed in the housing by connector 9, and the ripple panel surface is substantially parallel with the flow of flue gas direction.
