The specific embodiment
Consult shown in Figure 1ly, a kind of high-efficiency steam generator of the present utility model comprises that the cross section is the airtight container 1 of H shape, is provided with steam (vapor) outlet 11 on the top of airtight container 1; The under shed portion of airtight container 1 is combustion chamber 2, and the exhaust air chamber 3 that the upper shed portion of airtight container 1 is is provided with fire row 4 below combustion chamber 2, and bottom surface, airtight container 1 middle part is an evaporator main face 5, and evaporator main face 5 is a waveform, and the cross section is V; Being provided with flue tube 6 in the wave crest portion of evaporator main face 5 is communicated with combustion chamber 2 with exhaust air chamber 3; Be provided with heat collector 7 at the top of exhaust air chamber 3, be provided with float-ball type water compensating valve 8 at airtight container 1 outer wall, float-ball type water compensating valve 8 is communicated with airtight container 1 by pipeline, and heat collector 7 water inlets are connected with cold water pipe, and the outlet of heat collector 7 is communicated with float-ball type water compensating valve 8 by pipeline; Below evaporator main face 5, also be provided with the additional vaporization pipe 9 that one deck is provided with at interval by three rectangular tubes; Additional vaporization pipe 9 middle parts are provided with pipeline and are communicated with the wave crest portion of evaporator main face 5, and the two ends of additional vaporization pipe 9 are communicated with airtight container 1 side; Be provided with the horizontal fireguard 10 that is staggered in evaporator main face 5 bottom outside, horizontal fireguard 10 can be constrained to flame by " it " font and rise, and to increase flame in the time of staying of evaporator main face 5, improves the thermal efficiency.
Consult shown in Figure 2, the float-ball type water compensating valve 8 that the utility model adopted is made up of casing 81, the current limliting plug 83 that is placed on the ball float 82 in the casing 1 and is connected casing 1 top hot water inlet, current limliting plug 83 middle parts are provided with metering hole 83a, the bottom is provided with pallet 83b, and the outer surface of the inner surface of pallet 83b and ball float 82 adapts.
Consult shown in Figure 3ly, when the utility model specifically uses,,, when water level reaches specified water line, begin igniting by float-ball type water compensating valve 8 control flows by the electronic circuit control water level.Flame at first heats the hot water of additional vaporization pipe 9 the insides, until its boiling; Flame is subjected to horizontal fireguard 10 when continue rising stopping back changes direction, rushes at the V-shaped groove wall of evaporator main face 5 by subvertical angle, and the hot water that heats its top seethes with excitement until it; Last waste heat rises to exhaust air chamber 3 via flue tube 6, the sheet metal that need be by heat collector 7 when hot gas continue to rise and the gap of pipeline could the discharge machine outside, in this process, its heat major part is absorbed by heat collector 7, heat flowing cold water in heat collector 7 pipelines, made it to become hot water; The moving hot water of this plume flows to float-ball type water compensating valve 8 via pipeline, in connecting line enters airtight container 1, to replenish the moisture that vapors away, the water level in the airtight container 1 is remained unchanged substantially again.Steam in the airtight container 1 is through the top of flue tube 6, and the bottom of exhaust air chamber 3 and wall heating become superheated steam, are delivered on the apparatus (as steamer) that uses steam by steam (vapor) outlet 11 at last.
Consult Fig. 2, shown in Figure 3, the operation principle of float-ball type water compensating valve 8 is in the utility model: after this device enters stable duty, can produce stable quantity of steam in order to guarantee it, its water yield of replenishing also must be relatively stable; Water in the heat collector 7 can cause the water boiling too early in heat collector 7 pipes even produce " dry combustion method " phenomenon as stopping to flow after for a long time simultaneously.Therefore, after entering normal operating conditions,, also must guarantee regular the flowing of water in heat collector 7 pipes even the variation in water pressure of running water is bigger, and the horizontal plane of float-ball type water compensating valve 8 also can only slowly change up and down among a small circle, and float-ball type water compensating valve 8 designs just for this purpose.Under above-mentioned design, hydraulic pressure in heat collector 8 pipes is substantially equal to hydraulic pressure from the beginning, when running water is pressed in certain certain value, current enter its horizontal plane are improved, because airtight container 1 is communicated with the casing 81 of float-ball type water compensating valve 8, the result makes also and then rising of horizontal plane in the airtight container 1, and under the stable case, both can be considered equal.The result that horizontal plane raises, ball float 82 reduces the flow area of equivalence because buoyancy function produces contention effect to metering hole 83a, causes flow to reduce and horizontal plane is no longer raise; And when steady operation, the result of evaporation can make horizontal plane reduce, and horizontal plane reduces makes the pressure of 82 couples of metering hole 83a of ball float reduce again, and equivalent flow area is increased.The result that both cancel out each other can automatically form a kind of poised state---and by the metering function that a certain height of level face produces the buoyancy of ball float, the flow that causes entering float-ball type water compensating valve 8 equals the evaporation capacity of unit interval.At this moment, under this external world's hydraulic pressure, the horizontal plane in the airtight container 1 just is stabilized in this invariant position always.When the hydraulic pressure of running water increases, flow by metering hole 83a can increase, the water yield that enters airtight container 1 is bigger than evaporation capacity, horizontal plane is raise, the result that horizontal plane raises, the buoyancy of ball float 82 is increased, and the pressure of 82 couples of metering hole 83a of ball float can increase conversely, and the final level face can be equilibrated at again than on any position of original height.In like manner, when the hydraulic pressure of running water reduced, horizontal plane can be equilibrated at again than originally hanging down on the position of a bit.We can say that also under the identical situation of evaporation capacity, different horizontal plane correspondences different tap water hydraulics.
The diameter of the metering hole 83a diameter of current limliting plug 83 and ball float 82 and weight in the float-ball type water compensating valve 8 (being its overall buoyancy) can be by calculating behind the evaporation capacity of setting the unit interval, minimum hydraulic pressure, the highest hydraulic pressure, the pallet 83b of current limliting plug 83 is in order to set upright ball float 82, the hole heart of its center position alignment metering hole 83a to be designed.
The utility model is because its flame and thermal current heat a plurality of surfaces of airtight container 1 in the process that rises, so its evaporation capacity is more much bigger than the steam generator of the common enamelware pot formula of equal volume; And heat through heat collector 7 owing to enter the water of airtight container 1, the speed that therefore produces steam is also very fast; Steam is through the heating of flue tube 6 and exhaust air chamber 3 outer walls, and the superheated steam of formation can reach 140 ℃, makes the steam of exporting when being sent to the apparatus that uses steam through piping, still can keep higher temperature.Because after the absorption repeatedly of the heat of flame through water in this device and steam, when arriving outside the eliminating machine, it is very low that its temperature has become, therefore heat energy utilization rate of the present utility model can be a kind of energy-efficient product up to more than 80%.
