Description
Technical field the utility model relates to gas-heating apparatus field, is a kind of condensing type gas-fired wall-hung boiler.
Background technology burnt gas wall hanging furnace is as a kind of firing equipment of heating and bathing, the sorption enhanced rate of heat weighs the important indicator of gas furnace performance, the wall-hung boiler that current most domestic uses, smog discharge temperature is at 120 degrees centigrade, and energy consumption is higher, waste is larger.
Existing market newly increases a kind of condensing type wall-mounted furnace, it turn increases a secondary heat exchanger outside main heat exchanger, and with fume afterheat heat cycles heating water, first recirculated water enter main heat exchanger again by secondary heat exchanger, reduce exhaust gas temperature, improve combustion gas utilization rate.But owing to being heat cycles water, and the temperature of recirculated water is generally more than 25 degrees Celsius, flue gas and return water temperature differ less, are difficult to improve waste heat recovery rate.Again because the Gas phase Smoke of secondary heat exchanger and natural gas is met and get along well generation condensation, produce acid water, China's some areas domestic water is in alkalescence, and the materials'use of secondary heat exchanger is restricted, manufacturing process relative complex.
Novel practical content the utility model is to solve above-mentioned deficiency, improves waste heat recovery rate, reduces production cost and a kind of condensing type wall-mounted furnace of inventing.
Described device increases an aluminium-made plate type secondary heat exchanger above wall-hung boiler main heat exchanger.
The heating of secondary plate type heat exchanger enters the combustion air of combustion system.
Secondary heat exchanger, above main heat exchanger, is connect by coupling sleeve therebetween.
The side of coupling sleeve is stepped, and lower planes is parallel, and intermediate inclined panel is double does condensation shallow bid, lowest part perforate, and run in water pipe, as shown in Figure 5.
Blower fan horizontal is fixed on the top of heat exchanger, and bottom air inlet mouth is by gathering petticoat pipe and secondary heat exchanger exhanst gas outlet UNICOM, and exhaust outlet and body of heater flow back to wind port 7 UNICOM, and port 7 is arranged in sidewall of the furnace body.
Blower fan fan housing, fan blade all adopts aluminum material, prevents water logging corrosion.
Described plate type heat exchanger is made up of A, B two kinds of plates, and two kinds of plates form one group, and many groups are superimposed and are fixedly formed by sheet metal jacket or soldering.
90 degree, the plate periphery of described heat exchanger is turned up, and form the sidewall of plate, each sidewall all has one at a conplane step, sidewall is divided into interior terrace a and outer terrace b, the width of outer terrace is less than interior terrace, and the width of step is the thickness of plate, as shown in Figure 3.
A plate terrace in upper side wall opens slot k3, terrace perforate k4 in lower wall, position as shown in Figure 2
B plate at upper side wall (stagger A plate position of opening) perforate k5, terrace perforate k6 in the sidewall of plate side, as shown in Figure 4.
The distance in position of opening distance plate face is more than or equal to the width of outer terrace.
Identical, B plate also can in the left side wall top of plate and the perforate of right sidewall bottom.
A, B sheet form is identical, side-wall hole position is different, A, B plate is alternately after superposition, forms the gas approach 11 of A plate composition and exhanst gas outlet 12 (11 are made up of one group of k3 one group of k4,12) and independently the cold air import 13 that forms of hot chamber and B plate and cold air outlet 14 (13 are made up of one group of k6 one group of k5,14) and independently cold chamber.
Plate is vertically arranged, the centre on base is high, and outside is low, discharges in order to condensed water.
Identical, secondary heat exchanger can be arranged in the upper right of main heat exchanger, and exhaust blower is arranged on the left side of secondary heat exchanger, and the position of opening of A, B plate is adjusted accordingly.
Described device establishes isolation strip of paper used for sealing 9 in the middle part on the lower edge of the upper edge that secondary heat exchanger cold wind exports and cold wind import, enters to realize cold wind (fresh air) object entering combustion system after secondary heat exchanger carries out heat exchange again.In sum, the utility model comprises shell 8, control room is assisted in bottom and burn in top, Heat Room two large space, and upper space comprises burner 1, combustion chamber 2, main heat exchanger 3, coupling sleeve 4, secondary heat exchanger 5, isolation strip of paper used for sealing 9, poly-petticoat pipe 12, blower fan 6.Secondary heat exchanger is many group plate compositions, has cold wind import 13, cold wind outlet 14 and gas approach 11, exhanst gas outlet 12.Coupling sleeve side is stepped, have three faces, median surface doublely to do condense water disk, condensate pipe (Fig. 1,10) divided into by dish, upper and lower surfaces are parallel and and front and back sides surround coupling sleeve, as shown in Figure 5.Except burner, isolation strip of paper used for sealing, remaining part is sealed connection successively.Wherein coupling sleeve one end connects main heat exchanger, the other end and secondary heat exchanger connect (gas approach of secondary heat exchanger is in coupling sleeve), poly-petticoat pipe one end is connected in (exhanst gas outlet is in poly-petticoat pipe) around secondary heat exchanger exhanst gas outlet, the other end and blower fan connect, form combustion chamber (burning), main heat exchanger (heat absorption), coupling sleeve (connecting main heat exchanger and secondary heat exchanger), the hot chamber of secondary heat exchanger (absorption waste heat), poly-petticoat pipe (connecting secondary heat exchanger and blower fan), blower fan (combustion gas) is to the flue gas passage of heat flowing back to wind port, isolation strip of paper used for sealing 9 changes ripe device periphery at secondary, cold wind import 13 bottom, cold wind exports the position on 14 tops, heat exchanger outer space (cold air duct) is divided into two parts not connected up and down, first the cold air entered in stove from the return air channel flowing back to wind port enters upper part enters secondary heat exchanger 5 again cold chamber through cold wind import 13, absorbing cavity wall heat, export 14 by isolation strip of paper used for sealing bottom cold wind and flow into lower part, enter combustion chamber more combustion-supporting.
Description of drawings 1 is furnace binding schematic diagram, comprise that bottom controls ancillary chamber, burner 1, combustion chamber 2, main heat exchanger 3, coupling sleeve 4, secondary heat exchanger 5, blower fan 6, flows back to wind port 7, stove outer covering 8, isolation strip of paper used for sealing 9, condenser pipe 10, gas approach 11, poly-petticoat pipe (in cover heat exchanger exhanst gas outlet) 12, cold wind import 13, cold wind outlet 14.
Specific embodiments combustion gas is after the heat of combustion chambers burn is absorbed by main heat exchanger 3, and flue gas enters secondary heat exchanger import 11 through coupling sleeve 9, then enters the hot chamber of secondary heat exchanger, under the effect of blower fan, to exhanst gas outlet 12, outside blower fan discharge chamber.Due to the effect of blower fan, combustion chamber forms negative pressure, and fresh air outside enters body of heater isolation strip of paper used for sealing 9 top by chimney return air channel, enters the cold chamber of heat exchanger absorb heat by cold wind import 13, after cold wind outlet 14 is flowed out, enter combustion chamber.Through the flue gas generation condensation of secondary heat exchanger, condensed water flows to gas approach 11 along heat exchanger inclination base, drips to condense water disk, flows out from condenser pipe.
Because the heat transfer effect of plate type heat exchanger is outstanding, meanwhile, secondary heat exchanger heating combustion air, two kinds of fluid temperature differences are greater than heat cycles water temperature difference 20-40 degree Celsius, and waste heat recovery successful improves.
