Compared with the boiler with the same capacity, the utility model has the advantages of coal saving, electricity saving, natural ventilation, no noise, no pollution, ordinary pressure running, safety and reliability, and simultaneously has various use functions of heating, bathing, hot water use, etc.
Description
The utility model belongs to a kind of improved shelled hot water boiler, the normal pressure pan shell type multifunctional heating homogeneous solution-type reactor that particularly a kind of grate area is big, smoke-box thickness gas stroke is long.
At present, the heating hot water boiler that China uses is mostly reequiped by industrial steam boiler, this boiler thermal output low (about 60%), smoke dust discharge concentration height (more than 250MG/NM cube), environmental pollution is serious, though and need that adapted air blast, air-introduced machine and cleaner, power consumption height, noise are big, boiler bearing operation, poor stability.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of power consumption few, thermal efficiency height, the serial normal-pressure hot-water boiler of energy self smoke abatement and dust control.
Technical solution of the present utility model is: boiler adopts pan shell type structure, flue, fire grate, U type dividing plate, radiation horizontal water tube, horizontal stroke (or perpendicular) the formula compositions such as festoon and impact tube that are heated that are heated, and its special character is: grate area is big, the bottom entire area of flue is every putting fire grate.Combustion space is big, coal combustion is abundant, firepower is strong, in flue and horizontal (or perpendicular) convection current be heated and U type dividing plate be set between festoon and go up lower baffle plate, flue space on the combustion chamber is separated into I, II, a plurality of smoke-boxes of III, big leap ahead flue gas flow, make that whole boiler self heat absorption is good, fume afterheat is fully absorbed, improved the thermal efficiency (more than 75%) of boiler effectively, and help smoke abatement and dust control, make smoke dust discharge concentration be lower than national standard and require (below 200MG/NM cube).In burner hearth, arranged row's radiation be heated horizontal water tube, make the water in the burner hearth combustion flame direct baking heating horizontal water tube.
Below in conjunction with accompanying drawing, further describe specific structural features of the present utility model and embodiment.

Among the above-mentioned figure: 1 is the air intake shoot door, 2 are the blowdown base, 3 is magnetic valve, 4 is the backwater base, 5 is inspection opening, 6 is shell, 7 is water gage, 8 is impact tube, 9 are heat supply water pipe seat, 10 are the heat supply aqueduct valve, 11 is cleaning door, 12 is fire door, 13 is fire grate, 14 are the radiation horizontal water tube that is heated, 15 is lower baffle plate, 16 is smoke-box dedusting dividing plate, 17 is overhead gage, 18 is inspection opening, 19 are perpendicular (or horizontal) formula convection current festoon that is heated, 20 is U type dividing plate, 21 is flue, 22 is clear water dirt hand hole, 23 is fire-grating seat.
Energy-efficient serial normal-pressure hot-water boiler, constitute by be heated festoon 19 and impact tube 8 etc. of shell 6, flue 21, fire grate 13, U type dividing plate 20, convection current, it is characterized in that: the elongated fire grate 13 of shelving on the fire-grating seat 23 of flue 21 bottoms, be furnished with row's radiation horizontal water tube 14 that is heated in the burner hearth, be provided with U type dividing plate 20 on the horizontal water tube 14, on U type dividing plate 20, arranging the convection current festoon 19 that is heated, be mounted with upper and lower plate washer 17 and 15 respectively at convection current 19 of the festoons that are heated, constitute three smoke-boxes respectively.
With reference to Fig. 1-Fig. 3, shell 6, flue 21, fire door 12, fire-grating seat 23, U type dividing plate 20, last lower baffle plate 17,15 and flue dedusting dividing plate 16 all adopt the common low carbon steel plate to make welding assembly.Radiation is subjected to hot-water line 14, the convection current festoon 19 that is heated, and impact tube 8 and backwater base 4, heat supply water pipe seat 9 adopt all that seamless steel pipe is made, welding assembly.Fire grate 13 is an ironcasting, is shelved on the fire-grating seat 23.
Flue gas generates and flow process: coal is alternately dropped into by two fire doors 12, natural wind is by two deashings, shutter 1 enters, pass fire grate 13 and enter the coal seam, igniting back coal takes fire, produce the thermal-flame flue gas, above the direct baking heating furnace the one row radiation horizontal water tube 14 that is heated, high-temperature flue gas is by the radiation horizontal water tube 14 that is heated, enter the I smoke-box by U type dividing plate 20 tail rear portions, because of having lower baffle plate 15 and flue dedusting dividing plate 16 to intercept, flue gas enters the II smoke-box with the shaped form type of flow by dedusting dividing plate 16 to turnback angle, flue 21 top and walks around overhead gage 17 and enter the III smoke-box in the turnback angle again, the high-temperature flue gas of this moment is through flue dedusting dividing plate 16 and convection current the be heated abundant heat absorption and the depositing dust of festoon 19, become the low temperature purification flue gas, after entering impact tube 8, arrange to the high-altitude by chimney.
The boiler hot-water flow direction, the heating system backwater is by magnetic valve 3 control, and boiler water needs circulation time, and magnetic valve 3 is opened automatically, when not required, closes automatically, prevents that the spilling water phenomenon takes place when unattended.Backwater enters boiler and convection current festoon 19 and the radiation horizontal water tube 14 that is heated that is heated by backwater base 4, after the water heating, supplies with the heating or the system's hot water of having a bath by heat supply water pipe seat 9, valve 10.
Regularly discharge dirt in the boiler waters by two blowdown bases 2, can watch the position of water the boiler at any time from two water gages 7.Cleaning door 11 is for removing the cigarette ash above the U type dividing plate, regularly removing incrustation scale thing in the boiler by four jiaos of place's clear water dirt hand holes 22 at boiler middle part.
For the be heated normal-pressure hot-water boiler of festoon structure of Fig. 4-other two kinds of horizontal type convection current shown in Figure 8, in stove, do not establish the flue dedusting dividing plate, the be heated normal-pressure hot-water boiler of festoon structure of all the other structures and effect thereof and Fig. 1-vertical convection current shown in Figure 3 is all identical, high-temperature flue gas in the boiler furnace of this structure is equally along I, II, III smoke-box complications flow to impact tube, arrange to atmosphere from chimney, flue gas flow is long, and constantly washing away the horizontal type convection current festoon that is heated and to make the festoon that is heated, flue, the U template is every fully being heated, water temperature in the heating furnace, and the flue dust better effects if in the flue gas of having separated detention effectively.
This series normal-pressure hot-water boiler adopts gravity-flow ventilation,, need not mate air blast, air-introduced machine and cleaner, so simple installation, energy efficient, no subsidiary engine equipment operation noise.
In addition, the manhole of this stove communicates with atmosphere, and the water inlet of water circulating pump is connected with heat supply water pipe seat (being outlet pipe), does not have pressure during boiler operatiopn, so no explosion danger can be guaranteed handling safety.
