The advantages are that: the waste heat recovery problem of micro-operation resistance in gas-gas heat exchange of low-pressure or micro-pressure high-temperature tail gas, flue gas and the like can be effectively solved.
Description
Technical field
The present invention relates to heat-transfer equipment, all unmixed cross-flow heat-exchange apparatus of a kind of two side liquids is specially adapted to the heat-transfer equipment of the apparatus for energy recovery of gas-gas low pressure, little running resistance.
Technical background
Plate type heat exchangers or shell-and-tube heat exchangers of adopting in gas-gas heat transmission equipment at present, shell-and-tube heat exchanger can high temperature resistant, high pressure more, but that equipment takes up an area of is bigger, and the equipment running resistance is higher, and two collateral resistances are all at 0.01～0.05MPa (more than 10000～50000Pa); Plate type heat exchanger is extensively adopted because of the adjustment that its heat exchange efficiency is high, heat exchange area can be done certain limit; But the runner of board-like heat exchanger is complicated, and circulation area is little, and running resistance is big; Can reach 0.01～0.1MPa (10000～100000Pa); And easy fouling, and the operating pressure of high-temperature gases such as high-temperature tail gas, flue gas is merely 1000Pa～2000Pa, so existing heat transmission equipment is not suitable for or can't under low pressure or minute-pressure operating mode, use.
Summary of the invention
The purpose of this invention is to provide a kind of self-supporting full welded plate formula heat exchanger, can effectively solve low pressure or gas---the waste heat recovery problems of little running resistance in the gas heat exchange such as micro-pressure high-temperature tail gas, flue gas.
Solution of the present invention is: this self-supporting full welded plate formula heat exchanger; Be welded by adjacent heat exchanger plates sheet body; It is characterized in that even and the protruding frustum of a cone spaced apart and the depression frustum of a cone on the rectangular heat exchanger plate sheet, the frustum of a cone evenly is staggered in the sheet material both sides with behavior unit, and spacing all equates; Heat exchange plate only two parallel avris has flanging in opposite directions, and the flanging height is bump height and a cup depth sum on the plate; The heat exchange plate of half behind the flanging is 90 ° of arrangements in the same way with remaining half heat exchange plate in addition with adjacent flanging; And the protruding frustum of a cone of two plates is relative with the depression frustum of a cone; Flanging end face and 90 ° of angles, flanging plate edge not are welded to each other; Form the heat exchanger that passage is crossed as 90 ° cuboid each other, four relative respectively faces of heat exchanger prolong at the coplanar edge and weld out frame, join with the blower cover bolt or weld; The flow direction of hot and cold medium and runner can be chosen one of which wantonly, same medium be separated by 180 ° into and out of air-vent.
The advantage of this self-supporting full welded plate formula heat exchanger of the present invention is: be used for heat exchange 1000Pa under low, the minute-pressure condition, and be two kinds of immiscible fluids, generally be 100 ℃ under the waste heat recovery that contains steam.The aisle spare that forms behind the gas converting heat plate flanging is controlled at 1.5～2 times of air channel area; Make the flow resistance of hot and cold medium in heat exchanger be lower than duct resistance; Two cover air-vents; Cold wind is blown into, hot blast is reclaimed in the back of absorbing heat, and assurance equipment is at gas such as low pressure or micro-pressure high-temperature tail gas, flue gases---the normal operation in the gas heat exchange in the waste heat recovery of little running resistance.Be particularly suitable under the low pressure of chemical industry, pharmacy, tobacco processing, food-processing industry or minute-pressure operating mode, carrying out exchange heat, have that running resistance is little, heat exchange efficiency is high, simple and compact for structure, make characteristics such as easy, that sealing is reliable, runner is roomy.

The specific embodiment
A kind of self-supporting full welded plate formula heat exchanger is welded by heat exchanger plates self, sees Fig. 1; Fig. 2 is characterized in that the even protruding frustum of a cone 3 spaced apart and the depression frustum of a cone 4 on the rectangular heat exchanger plate sheet, and the frustum of a cone evenly is staggered in the sheet material two sides with behavior unit; Arrangement pitches is 50～500mm; Fig. 3 a, 3b, Fig. 4 a, 4b.The protruding frustum of a cone 3 is identical with the depression frustum of a cone 4 specifications, height 3～40mm, and top diameter is 5～40mm, and the base diameter of the frustum of a cone is 15～80mm, and the chamfer radius of the frustum of a cone is 2～15mm, highly all equates.
When making the heat exchanger of cuboid: will have the rectangular heat exchanger plate sheet two long limits or two minor faces of the protruding frustum of a cone or the depression frustum of a cone to carry out same parallel sides flanging in opposite directions respectively, the two long limits of heat exchange plate parallel sides or the flanging height of two minor faces equate with the protruding frustum of a cone of flanging side and the total height of depression frustum of a cone sum.During assembling; To roll over the heat exchange plate 1 of minor face and the heat exchange plate 2 on the long limit of folding respectively is spaced, arranges by identical flanging direction alignment with 90 ° of adjacent flangings; And the protruding frustum of a cone of two plates is relative with the depression frustum of a cone; Flanging end face and 90 ° of angles, flanging plate edge not are welded to each other, form two heat exchangers of cuboid that are crossed as 90 ° vertical and horizontal passage each other; Four relative respectively faces of heat exchanger prolong at the coplanar edge and weld out frame, join with the blower cover bolt or weld, and the flow direction of hot and cold medium and runner can choose at random, same medium be separated by 180 ° into and out of air-vent.Hot and cold gas advances orthogonal passage respectively, thereby realizes the purpose of exchange heat.
During the heat exchanger of the side's of manufacturing body: heat exchange plate only two parallel avris has flanging in opposite directions, and the heat exchange plate behind the half flanging and remaining half heat exchange plate in addition are with 90 ° of arrangements of adjacent flanging.
The heat exchanger of above-mentioned two kinds of shapes is characterized in that behind the heat exchange plate folding be the sheet material of the desired same size of finished product.
Described heat exchanger plates material is heat conductivility is good, corrosion resisting property is good corrosion resistant plate, two-phase stainless steel plate, aluminium sheet, titanium plate, nickel plate, monel plate etc., and heat exchange plate uses press compression moulding.
Self-supporting full welded plate formula heat exchanger of the present invention; Consider during design the aisle spare that forms behind the heat exchange plate flanging is controlled at 1.5～2 times of air channel usable floor area; Through the increase and decrease of heat exchanger fin quantity, control the flow velocity of hot and cold gas in heat exchanger at 1.5～5m/s.Confirm the flow velocity of gas according to the operating pressure of hot and cold gas, when pressure hangs down, select less flow velocity, vice versa.When hot and cold gas flow is big, suitably relax flow restriction, but should not be greater than 8～10m/s, otherwise can produce bigger running resistance.The flanging height of heat exchanger plates the best is at 10～18mm, according to the operating pressure of hot and cold gas and the flanging height of Flow-rate adjustment heat exchanger plates.Compare with total treating capacity, heat exchange area is at 80～150M
2/ ten thousand M
3, flanging height, gas flowing velocity in the air channel according to heat exchange plate divided by gas flow rate, calculate the circulation area of gas with total treating capacity, and then the specification of definite heat exchange plate, and the general device cumulative volume is at 0.8～2.0M
3/ ten thousand M
3, according to traffic condition, total treating capacity of separate unit heat exchanger (hot and cold gas flow summation) is not more than 200,000 M
3/ h, total heat can reach 3MW.
