Abstract

The utility model relates to a four or five return non-pressure boiler, which comprises a furnace body, a furnace casing, a furnace door, furnace bars, a furnace liner, a furnace arch, a fire-smoke pipe and a high cistern. The furnace arch is a semi-closed steel plate water jacket made of two layers of steel plates, and one end of the furnace arch is communicated with a circulation chamber. The fire-smoke pipe is divided into three or four layers that are arrayed in a slope shape. The high cistern is communicated with the circulation chamber via a connecting pipe inside the high cistern, and a return water controller is arranged inside the high cistern to control a water return pipe to endlessly return water into the circulation chamber. The utility model has the advantages of simple structure, high thermal efficiency and long service life; the utility model conveniently removes ash and dirt, can ensure that the boiler runs in high efficiency and saves energy in a long term, can satisfy user's requirements of heating and taking a bath, and is safe and non-pressure.

Description

Four backhauls or five backhaul pressure-less boilers
The utility model belongs to a kind of life use stove tool, particularly a kind of boiler of making fuel with solid.
Boiler is the heat power equipment that extensively adopts during people live, and is generally single backhaul or three return structures, the high-temperature flue gas that the boiler fuel combustion produces, and flow process is not long, does not pass through abundant heat exchange, and the firepower utilization rate is not high, and heat waste is big, has reduced the thermal efficiency.Owing to do not adopt decompression technology, conventional boiler body often pressurized is bigger, and service life is not long.Smooth and easy in order to ventilate, conventional boiler often adopts air-introduced machine, air blast, and power consumption is serious.
Task of the present utility model is the deficiency at conventional boiler, a kind of firepower utilization rate height is provided, the gravity-flow ventilation ability is arranged, does not have pressure, efficient, long-life boiler for domestic.
The technical solution of the utility model is such.This pressure-less boiler comprises body of heater, furnace shell, fire door, fire bars, flue, elevated tank, backwater controller, it is characterized in that chimney arch is arranged in the body of heater, chimney arch is the semiclosed steel plate water jacket that two-layered steel plates is made, one end communicates with circular chamber, three layers or four number of plies row pyrotechnics pipes are arranged in the circular chamber, three layers or four number of plies row pyrotechnics pipes be arranged as gradient shape, be beneficial to nature air inducing.There is smoke-returning box the body of heater both sides, and chimney arch, pyrotechnics pipe, smoke-returning box are formed the flue gas return structures jointly, and elevated tank communicates with circular chamber by tube connector, by backwater controller control return pipe through water inlet to the circular chamber backwater.
The utility model is owing to adopt semiclosed chimney arch and three layers or four layers of pyrotechnics pipe, the high-temperature flue gas that the burner hearth fuel combustion is produced, cross chimney arch earlier, enter back smoke-box again, pass through each layer pyrotechnics pipe one by one, form four backhauls or five backhauls, discharge along chimney by going out smoke box at last, sufficiently long backhaul makes heat exchange abundant, and the thermal efficiency is higher.Because being gradient shape, the pyrotechnics pipe arranges, can natural air inducing by chimney, and do not need air-introduced machine, air blast to get final product the well-ventilated, reach the powerful purpose of firepower.Because backwater controller acts on outside the boiler body pressure of external circulating system to the control of return pipe in the elevated tank, has prolonged the service life of boiler.Because well-ventilated, sufficient combustion, thermal efficiency height, fuel saving greatly.At heating area is 7000-10000M 2Situation under, per hour only use standard coal 110kg, compare conventional boiler, save coal 60kg.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is the utility model Facad structure schematic diagram.
Fig. 2 is the utility model side structure schematic diagram.
As shown in the figure, each associated components of the present utility model is: body of heater 1, burner hearth 2, chimney arch 3, pyrotechnics pipe 4, scrubbing mouth 5, water inlet 6, fire bars 7, dividing plate 8, smoke-returning box 9, heat-insulation layer 10, fire door 11, Pressure gauge 12, thermometer 13, circular chamber 14, delivery port 15, service ports 16, elevated tank 17, backwater controller 18, overflow pipe 19, return pipe 20, chimney 21, go out smoke box 22, flue 23, furnace shell 24.
Find out from figure, the utility model comprises body of heater 1, furnace shell 24, fire door 11, fire bars 7, flue 23, elevated tank 17, backwater controller 18, it is characterized in that chimney arch 3 is arranged in the body of heater 1, the semiclosed steel plate water jacket that chimney arch 3 is made for two-layered steel plates, one end communicates with circular chamber 14, and three layers or four number of plies row pyrotechnics pipes 4 are arranged in the circular chamber 14.Three layers or four number of plies row pyrotechnics pipes 4 are gradient shape and arrange.
The course of work of the present utility model is such.The high-temperature flue gas that burner hearth 2 fuel combustion produce is crossed semiclosed chimney arch 3 and is arrived smoke-returning box 9, through three or four backhauls of pyrotechnics pipe 4 circulations, water in high-temperature flue gas heat energy and the circular chamber is fully exchanged, high temperature pyrotechnics in the burner hearth 2 radiation simultaneously flue 23 inwalls, make water temperature rising in the circular chamber, form Natural Circulation, by the external circulating system that delivery port 15 and return pipe 20, water inlet 6 are formed, the purpose of reach heating, having a bath.Flue 23 is set as circular-arc, and the incrustation scale that is beneficial to the generation of pyrotechnics pipe outer wall comes off and then is slipped to circular chamber 14 bottoms naturally, manually discharges through scrubbing mouth 5.Elevated tank 7 communicates all the time with circular chamber 14, provides backwater through water inlet 6 to circular chamber by backwater controller 18 control return pipes 20.The hydraulic pressure of external circulating system only acts on outside the boiler body like this, and boiler body is pressurized not, can increase the service life.The side of smoke-returning box 9 is removable covers, can be easy to open, and removes the crock in the pyrotechnics pipe and changes the pyrotechnics pipe that damages.
