Description

Vertical hot-water boiler

The utility model relates to the civilian vertical type water heater boiler of a kind of boiler, particularly a kind of efficient energy-saving.

Present stage, urban and rural residents, the particularly dwelling house of Fen Saning (as outskirts of a town, small towns etc.) warmed oneself, and often adopted self-control boiler band soil heating installation.This boiler combustion condition is poor, and the thermal efficiency is low.For this reason, the various civil boilers of people's development and design, a kind of double water jacket energy-saving water-heating dual-purpose stove is disclosed as Chinese patent CN89200041.4 number, it is to carry out heat exchange with heat radiation form and heat conduction and convection current, inner water sleeve is two-sided being heated, reflection fire lid back is set forms the combustion chamber, though it is fast that this technology has firing rate, fuel consumption is big, and for example, a kind of vertical hot water (steam) boiler is disclosed for Chinese patent CN87202287 number, it is to adopt the individual layer fire grate, fires on the naked light, and fire coal is sent into the combustion chamber automatically by the following formula feeder, after fire coal is lighted, pyrotechnics is through burner hearth, first quarter moon arch and the fire hole of leading all around thereof enter flue, and flue gas carries out vertical even heat exchange with the inwall of boiler with the spiral coil heat exchanger, but and pass through following formula feeder automatically coal feeding, automatically coal-fired, though it has long service life, the characteristics of fuel saving, it is also comparatively complicated that it makes the processing difficulties structure, the cost height is not suitable for urban and rural residents' every family and uses separately.

The utility model improves at the problem that prior art exists.Provide a kind of simple in structure, processing and manufacturing easily, cost is low, and is easy to use, and deashing reduces exhaust gas temperature, good energy-conserving effect, the vertical type water heater boiler that the thermal efficiency is higher easily.

The utility model is achieved by following manner: a kind of vertical type water heater boiler, upper hose and the downcomer and the blow-off pipe of chimney that the furnace lining of upper and lower fire door that comprises the body of heater of inside and outside water jacket formation and be provided with below and inside setting and fire grate, body of heater top center are provided with and outlet pipe and upper of furnace body and bottom setting, it is characterized in that: in the body of heater that said inside and outside water jacket constitutes, its inside and outside water jacket is a circular cross-section, i.e. body of heater water jacket outside periphery inwardly is followed successively by circle.Annular flue and circular inner water sleeve are provided with day some rounded fire tube flues of evenly arranging in the wherein circular inner water sleeve, in body of heater internal upper part and annular flue deashing device is set simultaneously.

Said deashing device, have and be connected on the upper and lower baffle plate in inner water sleeve center and rotating upper and lower horizontal gird by bolt, nut, be provided with the left and right ash-removing plate that matches with its width dimensions and be connected with upper and lower horizontal gird in the annular flue between upper and lower water crossbeam, on last horizontal gird, be provided with identical with body of heater upper sealing plate shape and relatively turnable left and right arc ash-removing plate, and below following horizontal gird two ends, be respectively equipped with pin.Fire tube flue in the present technique also has been equipped with the wire brush of deashing with stock in addition, the other end of its stock is made annulus, the wire brush that this deashing is used is except that the deashing that is used for the fire tube flue, the annulus of its afterbody can be used for spurring the whole rotation of deashing device to remove the ash in upper of furnace body and the annular flue, specifically the annulus with wire brush entangles on the pin of deashing device bottom, draw it to rotate 180 °, and then the annulus of wire brush is entangled another pin, draw again and rotate remaining 180 °.The grey full scale clearance of whole like this upper of furnace body and full annular flue has been fallen.The course of work of the present utility model is: feedwater is outside downcomer 2 enters in the water jacket 30, heating along with water jacket inside and outside the body of heater, the circulation feedwater is punished into two parts at body of heater inner water sleeve downcomer 10, flow in part continuation water jacket 30 tops outside body of heater, another part is gone in the inner water sleeve 33, after continuing heating, hot water flows back to outer water jacket 30 by inner water sleeve upper hose 21, inside and outside water jacket 33, hot water in 30 is together in outlet pipe 19 is delivered to heating plant or system, meanwhile, the course of work of boiler smoke is: divide two parts from the high-temperature flue gas of burner hearth ejection, at first body of heater etc. is heated based on radiation, treat then to be heated after flue gas enters flue with convection current, and in conjunction with heat conduction etc., wherein a part enters fire tube flue 34, after the inner water sleeve heat exchange, flue-gas temperature reduces gradually, another part enters annular flue 32, after the outer water jacket heat exchange of body of heater, temperature also reduces gradually, and the two converges to enter together in the chimney 18 in upper of furnace body and is discharged in the atmosphere, and the hot water circuit heat supply in the present technique mainly is by the gravity circulation, during installation, water tank communicates with atmosphere, and is safe and reliable, need not establish Pressure gauge, water-thermometer etc., during manufacturing, through strength check, with certain thickness steel plate welding, through the water pressure test, satisfy instructions for use, the furnace bottom face only otherwise exceeding ground level get final product is built a grey hole at furnace bottom with brick during installation, for ventilation with deposit ashes usefulness, pipeline is installed in its highest point and establishes an exhaust apparatus, and its installation is identical with native heating installation installation method.Present technique also can increase furnace diameter an intermediate annular water sleeve intermediate annular flue is set between inside and outside water jacket 33,30 again according to the increase of heating area, and corresponding each several part changes little, sees figure seven, eight, nine, on its fundamental diagram.

The utility model is compared with prior art, has compact conformation, and floor space is little; Easy to operate, firing rate is fast, and the thermal efficiency is higher, and is safe in utilization waits focus.
