Abstract
The present invention relates to a smoke reflux boiler with closed-top combustion chamber and is characterized by that the external water jacket is used as its archivolt external shell, and in the space between said external shell and internal water jacket and combustion furnace a smoke reflux flue is formed whose interior is hot, exterior is cold, heat surface airflow is risen and cold surface airflow is fallen, so that in the specific smoke reflux flue the gas which is not completely burnt in the smoke is carried by fresh air risen on the heat surface and returned into the combustion chamber to make repeated combustion, and its heat quantity can be repeatedly absorbed so as to minimize the smoke discharge of said boiler, and can eliminate chimney, and can minimize smoke discharge pollution.
Description
The present invention is a kind of boiler of flow heated water.The main gravitational difference that causes by the density contrast of hot cigarette and normal pressure atmosphere of existing conventional boiler smoke evacuation, hot cigarette is formed in chimney under the effect of rising suction makes the combustion product gases in the boiler wear thorax and mistake, heat-absorbing structure commonly used also just is used for stopping and cutting apart thermal current and washes away heat-absorbent surface and improve heat absorption efficiency, but thermal current always passes to walk limit and dead band from the little space of resistance, the current density that is cooled on heat-absorbent surface increases power that losing expands rises and is formed with the layer of cold gas of being detained downward trend and claims " cold boundary layer ", the cold air of sinking is detained, cause " cold boundary layer " thickening on the boiler heat-absorbent surface, the heat absorption efficiency of boiler is difficult to improve, and existing boiler structure does not have chimney smoke evacuation not burn or causes imperfect combustion.
The present invention sets up the approximate such celestial body of atmosphere in boiler, in this celestial body, set up a relative cold airflow decline smoke evacuation, thermal current rising oxygen supply is also carried the temperature field that partial fume forms backflow, realize setting up the brand-new current system that satisfies the oxygen supply of boiler combustion smoke return not by chimney suction.
The present invention adopts bind " outer water jacket " (3) as atmospheric day body case, see Fig. 1, its inner space is as the atmosphere of conventional boiler smoke evacuation, only end opening opens wide, dress " inner water sleeve " (4) and " burner block " (6) and have " connection water pipe " (9) to communicate with bottom, " inner water sleeve " (4) in that " outer water jacket " (3) are high-end within it, " advancing cold water pipe " (8) are equipped with in " outer water jacket " (3) bottom, and there is high some means of deflation (2) on last top.Top, " inner water sleeve " (4) is high-end should be with clearance seal when having " hot-water outlet pipe " (1) to pass " outer water jacket " (3).
" inner water sleeve " (4) cover on and form " closed-top combustion chamber " (5) on the flame of " burner block " (6) and only leave in " burner block " (6) upper edge and " inner water sleeve " (4) end opening between " the air inlet crack of discharging fume " (10) and " inner water sleeve " (4) " outer water jacket " (3), and " smoke return flue " (7) left between " burner block " (6) " outer water jacket " (3) communicate.
Adopt said structure, (8) enter because cold water " advances cold water pipe " from " outer water jacket " (3) bottom, make " outer water jacket " (3) form the sky body case of a cold wall; " closed-top combustion chamber " (5) that constitute between " inner water sleeve " (4) " burner block " (6) just are equivalent to be similar to the boiler in celestial body, when combustion flame and flue gas in " closed-top combustion chamber " (5), rise assemble " inner water sleeve " (5) cooling of being bound sink to along its inwall discharge from " smoke evacuation air inlet crack " (10) first half after, because rising to the top of " celestial body " in the stove, cooled off by " outer water jacket " (3) of low temperature again " inner water sleeve " (4), the hot inevitable edge of this part flue gas upper surface, sink down into the unlimited end opening (see figure 1) that discharges out of the furnace along its inwall, simultaneously in the inboard rising of burner block (6) outer wall hot side heating fresh air " along the smoke return flue " (7), part was difficult for being cooled during huyashi-chuuka (cold chinese-style noodles) sank to discharging fume outside carrying, and the slower hot cigarette backflow of sinking enters " closed-top combustion chamber " (5) and burns once more.
Because imperfect combustion material such as carbon, hydrogen, sulphur and main compound thereof are low weight in the smoke evacuation, its thermal capacity is extruded huyashi-chuuka (cold chinese-style noodles) near hot side than the Da Yi come-up by the inertia matter of cooling sinking rapidly, heat once more to carry and flow to " closed-top combustion chamber " (5) and participate in burning and be heated the rising fresh air, obviously burning is the Infinite Cyclic process to realize refluxing repeatedly by this partial fume repeatedly, reaches so the thing minimizing discharge of harmful gases of fully burning.
The present invention has mainly solved the fresh air of smoke evacuation and backflow in same special flue, and utilize when cooling off smoke evacuation, the sinking that easily is cooled of inertia matter, speed is fast, and be back to the combustion chamber after the fresh air hot-fluid heating that the combustible cooling is easily risen slowly, started the new revolution that energy-saving, environmental protection boiler is made.
" cold smoke " i.e. after the present invention increases flue gas cools down volume-diminished density by huyashi-chuuka (cold chinese-style noodles) heat absorption in the celestial body of sealing be " heavy cigarette " discharging of sinking, and just can discharge out of the furnace after flue gas must being cooled to can sink to the density that " sealing celestial body " end opening is " outer water jacket " (3) end opening.Wherein very most of flue gas is cooled into liquid, and the particle in the bonding smoke evacuation falls on the ground.And smoke evacuation (by cooling) and heat absorption (adding hot water) are finished among same useful energy transfer process, have reduced the investment of special-purpose fume extractor.
Basic structure of the present invention and principle are mainly used in manufacturing energy-saving and environmentally-friendly gas fired boiler, oil burning boiler; Do with anthracite fuel boiler of the present invention accomplish to be reduced to the smoke evacuation not obvious, can cancel chimney, smoke-discharging pollution is narrowed down to only in the boiler room, carries out environmental protection treatment, avoided boiler exhaust gas directly to pollute the atmosphere.
The present invention leans against to set up in the boiler that binds to cause gravitational difference by density contrast, design smoke evacuation and return-flow system, therefore boiler can not tilt to place, and its " inner water sleeve " (4) and " outer water jacket " (3) end opening should keep level, should not surpass 2 ° of (degree) (see figure 2)s with the horizontal error angle.
Obviously the present invention increases backflow and preferably increases " the temperature of burner block wall; rise for keeping the heating fresh air; " burner block " (6) " wall " temperature in " smoke return flue " (7) should not be lower than 200 ℃; when heated rising backflow was not enough, the power of the fresh air of its rising should be replenished by positive pressure source.
" closed-top combustion chamber " (5) among the present invention, the capacity of the main combustion exhaust gas with boiler with " smoke return flue " (7) size, shape between " inner water sleeve " (4) " burner block " (6) in " smoke evacuation air inlet crack " (10) and " outer water jacket " (3) and be heated the entry of water and go out water temperature difference relevant can only be tested definite by above-mentioned different actual conditionses.
