Description

Continuous water supply tea boiler

The utility model relates to a kind of vertical Natural Circulation continuous water supply heat pipe drinking water boiler, belongs to burning and cooking stove technical field.

At present, drinking water boiler commonly used mostly is discontinuous water supply, and it is drinkable that whole stove water clean burn is opened the rear, and this brings many inconvenience to life.88 years disclosed CN88203587U patent application technology, " sluggard " drinking water boiler of a kind of disposable coal of boiling water without interruption is provided, many saving graces are arranged really, but also exist some shortcomings, be similar to original " the baked wheaten cake heart " boiler as this boiler, heating surface is less, and the fume afterheat utilization rate is not high; Body of heater adopts square structure, compares with circular configuration, uses steel more, and metal thermal intensity is low etc.

Task of the present utility model is: transformed on the basis of the existing vertical drinking water boiler type of furnace, make it both to keep the characteristics of original boiler, make the interior current of stove have good Natural Circulation again, boiling water, hot water naturally separately reach the purpose of boiling water without interruption.Provide a kind of energy-efficient to society, the novel drinking water boiler that smoke medicining dust-removing effect is good, easy to use.

The utility model can be made anti-burning as required, just burn different forms, and Figure of description is the section of structure of the anti-burning type of furnace of the present utility model.

Below in conjunction with description of drawings essential structure of the present utility model.

Mainly heat part, moisturizing part four parts form the utility model again by upper drum, lower drum, circulation.

Flue 1 welds by impact tube 3 and " U " shape leftover bits and pieces 4 with stove outer covering 2, constitutes the main body of boiler, and the space of middle sealing is a drum, and doughnut-shaped steel plate 5 of welding is divided into two drum in drum, formation upper drum 6 and lower drum 7.Circulation heat part again is made up of hot again riser of " U " shape and down-comer 8.The hot again riser of " U " shape is by guide wire 9, heat tube 10 and the tube bank 11 of rising are formed again.The heat tube is located at the top of upper furnace 12 again, is made of the space that is welded on the folded one-tenth of two block plates in the flue; Guide wire 9 one terminates at the bottom of heat tube again, and the other end causes the lower drum top; Heat tube top periphery is connected to one group of tube bank 11 of rising again, and the other end of the tube bank of rising passes furnace gall head and causes upper drum.Be connected to down-comer 8 between stove external upper drum 6 bottoms and lower drum 7 tops, down-comer is provided with non-return valve 13.Be smoke-box 14 above the heat tube again, between smoke-box and upper drum, be provided with one group of steel--hydro-thermal pipe 15.The external position a little more than the upper drum height of stove is provided with water supply tank 16, and water supply tank and running water pipe 17 join, and the running water pipe outlet is provided with ball-cock assembly 18, and the water supply tank bottom is connected to filling pipe 19, and the filling pipe other end is connected on the bottom of lower drum.Draw logical steam pipe 20 respectively at the top of upper and lower drum, logical steam pipe causes the height that is higher than water supply tank, inserts then in the water supply tank water.Be connected to boiled water pipe 21 and hot-water line 22 respectively on the top of upper and lower drum.Boiler drum bottom and hot again tube bottom pick out blow-off pipe 23 respectively up and down.The certain angle of circular steel plate inclination of doughnut-shaped steel plate 5 and hot again tube 10 bottoms, the aspect blow-off pipe.

The boiler combustion part-structure is basic identical with back firing boiler commonly used.Be summarized as follows: be provided with upper furnace 12, lower hearth 24, reach cinder chamber 25, and be provided with shoot door 26, upper furnace door 27, lower furnace door 28 and clean-out door 29.Upper fire-grating 30 is made by seamless steel pipe, and having certain inclination angle will be communicated with before and after the lower drum.Smoke pipe 31 by one group of periphery between lower hearth and the smoke-box 14 links to each other, and smoke pipe is located in the lower drum.The outlet of impact tube 3 is provided with butterfly cigarette valve 32.

Other is the same with existing boiler, is provided with in position as required and draws mouth and access hole clearly.

Below in conjunction with accompanying drawing plume journey of the present utility model and current journey are specified:

The plume journey: coal is in upper furnace 12 internal combustion, and flue gas passes upper fire-grating 30 and enters lower hearth 24, and the smoke pipe 31 through being located at periphery enters smoke-box 14 then, causes chimney by impact tube 3 at last and discharges.

The current journey: water heats through three times in boiler.Heating for the first time: when boiler combustion, the water in the lower drum 7 are by the heat transfer of flue 1, upper fire-grating 30 and smoke pipe 31, and water temperature raises, and determined that by the characteristic of water the water temperature at top is the highest in the lower drum.Heating for the second time: the water of upper drum top higher temperature causes heat tube 10 again through guide wire 9, hyperthermia radiation heat, top and the high-temperature flue gas heat convection in the upper furnace 12 accepted in heat tube bottom again, water temperature is raise once more, by the tube bank 11 of rising, rise to upper drum while being heated then.Heating for the third time: in upper drum, water is by furnace gall head, impact tube 3 and high efficient heat exchanging element--and heat pipe 15 further heats.The circulation of nature water: rise after water is heated in lower drum, guide wire 9 causes heat tube again with the water of lower drum higher temperature, is heated once more after the tube bank 11 of rising rises to upper drum 6, and water has passed through the process of " U " shape rising in stove; The water of upper drum bottom lower temperature drops to the top of lower drum by down-comer 8.So, because the natural water circulation between the lower drum is finished in the effect of the bulk density difference of different temperatures water.The effect of non-return valve 13 is only to allow water to flow from top to bottom.After water clean burn in thermometer shows upper drum is opened, can outwards take boiling water at any time by boiled water pipe 21, whenever what are taken, how many running water water supply tank 16 will be automatically replenishes by filling pipe 19 downward boiler drum bottoms, the water how many lower drum top higher temperatures are also arranged simultaneously by guide wire 9, again heat tube 10, rise and restrain 11 and be heated to and enter upper drum after boiling.

The logical steam pipe 20 that last lower drum top is provided with is used for boiler and just moves the usefulness of water-filling exhaust and when the water vapor in the drum, steam is drawn, and the steam of drawing heats moisturizing in water supply tank.

The effect of butterfly cigarette valve 32 is: when water consumption hour, turn down or close smoke evacuation, regulate burning and use.

The utility model has following advantage: 1, boiling water is supplied with continuously, ready access upon use, and the moisturizing automatic control need not the personal management.2, current Natural Circulation in the boiler, current are organized, and have adopted adopting heat pipes for heat transfer, thermal efficiency height.3, can adopt the anti-burning type of furnace, and being provided with of tube bank of rising there are certain barrier effect, good dedusting effect to flue dust.4, adopt the vertical drinking water boiler type of furnace, existing miniature boiler factory can produce not needing to increase under the situation of any equipment investment.

Below by accompanying drawing an embodiment of the present utility model is explained, in the hope of further the utility model being described.Present embodiment is manufactured and is formed boiler diameter 800mm, flue diameter 520mm, the high 800mm of upper drum with reference to the anti-drinking water boiler drawing that burns of original vertical heat pipe, the high 200mm of heat tube rises and restrains 8, diameter DW32, one of guide wire again, diameter DW40, one of down-comer, diameter DW40.The conventional configurations no significant difference of remainder and existing boiler repeats no more.
