Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model comprises casing 1, the board-like heat exchange module 2 being positioned at casing 1 inside and the header box 4 being connected to board-like heat exchange module 2 one end and perpendicular to the weir plate 3 arranged bottom casing 1, the evaporating area 5 that casing 1 inside is divided into upper end to be communicated with by overflow ducts by weir plate 3 and overflow area 6, described overflow ducts is higher than board-like heat exchange module, described board-like heat exchange module is positioned at evaporating area, the bottom of casing is provided with the inlet 7 being positioned at evaporating area, the bottom of described casing is provided with the liquid outlet 8 being positioned at overflow area, described casing top is provided with gas outlet 9, the liquid complete immersed plate type heat exchange module arranged in guarantee evaporating area of overflow area, overflow area is as the buffering area of overflowing liquid, collect the liquid overflowed, exported by liquid outlet and enter evaporating area through inlet again, realize the circulation of liquid in case mutual, the gas evaporated is exported by gas outlet, the impurity of the impact of the bubbling through the water column evaporation contained in the liquid of evaporating area can be discharged by overflow area in time, improves evaporation efficiency, certainly, according to real work needs, also circulating and evaporating can not be carried out, the upper and lower side port of simultaneously casing 1 is also provided with pull bar or lacing wire (not shown), for fixing and spacing board-like heat exchange module 2,
Wherein board-like heat exchange module can be fixedly connected with weir plate, makes board-like heat exchange module fixing firm;
Board-like heat exchange module also can not be connected with weir plate, now board-like heat exchange module edge and weir plate are spaced a distance, can avoid because board-like heat exchange module temperature acute variation causes deformation thus causes device interior to extrude like this, prevent the problem of seal failure and dielectric leakage, improve equipment life.
The upper and lower two ends of described header box are respectively equipped with thermal source inlet 44 and thermal source outlet 45, are provided with dividing plate 42 in header box, header box are divided into the inlet distribution district 41 be communicated with thermal source inlet and the outlet doab 43 be communicated with thermal source outlet;
Board-like heat exchange module comprises several evenly distributed heat exchanger plates to 21, described heat exchanger plates between 21 for be communicated with inlet and and the liquid once-through passage of gas outlet, described heat exchanger plates is internally for being communicated with the medium folding Cheng Liudao of described inlet distribution district and outlet doab, and described medium folding Cheng Liudao comprises and severally has circumferential passageway 212 that standalone media imports and exports and be arranged in circumferential passageway the pass partition 211 making medium along its reciprocal folding Cheng Liudong in circumferential passageway;
Owing to being provided with the pass partition making medium along its reciprocal folding Cheng Liudong in circumferential passageway, make medium not need to flow out plate when realizing folding Cheng Huanre and enter plate again, folding journey space can be set in casing both sides in addition, therefore, box volume is little, lightweight, pressure drop is little, cost is low, heat transfer efficiency is high, compact conformation.
Heat exchanger plates can adopt carbon steel, stainless steel, titanium and titanium alloys, nickel and nickel-base alloy thereof or other steel grade or non-ferrous metal, and its temperature resistant range is at-196 ~ 1200 DEG C;
In circumferential passageway 212 and the welding of pass partition 211 place after two heat exchanger plates are superimposed, circumferential passageway 212 sequential welding, pass partition 211 can compress contact connection, sequential welding, intermittent weld or multiple spot welding, forms heat exchanger plates to 21; The ripple geometry of heat exchanger plates both sides is symmetrical or asymmetric, and namely the ripple's depth of both sides can be equal, also can not wait; The heat exchanger plates both sides ripple of compression molding can be various corrugated form, and ripple also plays and strengthens the effect that heat exchanger plates bears pressure medium simultaneously; Ripple also realizes by weldering muscle, joint pin mode.
During kettle type reboiler work of the present utility model, in evaporating area liquid by board-like heat exchange module constantly and heat source medium heat exchange occur to volatilize or evaporate, discharged by gas outlet, liquid measure in evaporating area constantly reduces, inlet constantly can supplement the liquid measure in evaporating area, certainly, also can form loop at liquid outlet and inlet, the circulation realizing liquid in case is mutual, makes liquid circulation flow move thermal evaporation or volatilization;
In this equipment, heat source medium can be gas, liquid or gas-liquid mixture, for the thermal source being carried out heat release by condensation, its circumferential passageway can be the structure that flow cross-section areas reduces gradually along media flow direction, now heat source medium is lowered the temperature liquefaction after the effect of board-like heat exchange module, pressure in circumferential passageway is significantly reduced, utilizes the pressure official post heat source medium of both sides constantly to be entered reboiler by siphon.
Overflow ducts in this example can for being located at the spout hole on weir plate, and now weir plate four end is connected with casing respectively, makes weir plate intensity comparatively large, can bear larger pressure;
Certainly, the region that overflow ducts also can surround for weir plate upper end and box house, now overflow ducts is comparatively open, can not stop the discharge of impurity in evaporating area.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
