Description

Boiler jacket type boiler

The utility model relates to a kind of boiler, especially a kind of smaller hard flour pancake boiler that high-temperature flue gas is risen at the stove inside spin.

The tendency that existing fixed fire grate smaller hard flour pancake boiler, high-temperature flue gas leave behind the burner hearth has two kinds substantially.A kind of is that straight line rises, owing to be subjected to the restriction of body of heater height, flue gas flow is short, makes not clean-burning in a large number carbon black enter atmosphere with chimney, the over-emitting black exhaust phenomenon occurs, causes environmental pollution.Another kind is at the curved water pipe of boiler arranged around, makes flue gas enter chimney around boiler after one week, though prolonged flue gas flow, flue gas resistance is bigger, needs configuration drum, air-introduced machine, and consumed power also brings mechanical noise, and the boiler complex manufacturing technology, the cost height.

The purpose of this utility model provide smoke medicining dust-removing effect better and the thermal efficiency higher, and can realize the smaller hard flour pancake boiler that a stove is dual-purpose.

Fig. 1 is the schematic diagram that produces the smaller hard flour pancake boiler of hot water;

Fig. 2 is the schematic diagram that produces the smaller hard flour pancake boiler of drinking water when producing hot water.

The purpose of this utility model can be achieved by the following measures: this boiler is made of shell 4, flue 6, in the bottom of flue 6 slag notch 16 is arranged; In the top of slag notch 16, the flue 6 fixed grate 18 is arranged, above fixed grate 18, have to ort 19; Outside the flue 6 shell 4 is arranged, inner core 9 is arranged in the flue 6, water return outlet 15 is arranged at the bottom of shell 4, and there is the cleaning

door

24 and 26 by shell 4 and flue 6 at the middle part; The big section of burner hearth 20 tops is covered by the hydroecium 23 that links to each other with flue 6, and hydroecium 23 bottom surfaces and burner hearth 20 rear portions are respectively Arc radiant arch 22 and rear arch 14 that refractory material is made have exhanst gas outlet 12 between arc radiant arch 22 and rear arch 14, there is the secondary air inlet 13 by flue 6 and shell 4 exhanst gas outlet 12 belows; In flue 6, above the hydroecium 23 inner core 9 is arranged, inner core 9 tops link to each other with flue 6, and hot water outlet 11 is arranged at the bottom, and inner core 9 is provided with hydroecium 10 and the hydroecium 8 that links to each other with flue 6 with flue between 6 ring weeks; Hydroecium 10 is stairstepping around inner core 9 and arranges; Top in the flue 6 is one group of down tube 7; In flue 6 top shells 4, smoke pipe 2 is arranged, 3～6 branched pipes of smoke pipe 2 bottoms link to each other with flue 6, and top links to each other with shell 4 and stretches out shell 4, and end face links to each other with chimney 1.

The utility model also can be realized by following measure: be connected with in the bottom of inner core 9 feed in the burner hearth 20, the arc radiation encircles the flue gas disturbance device 21 below 22, this device can be cylinder cylinder, polygon or plate shaped.Inner core 9 and flue are provided with 3～8 and are fan-shaped hydroecium 10 between 6 ring weeks, this hydroecium 10 is stairstepping around inner core 9 and arranges.So-called hydroecium 10 is circle for fan-shaped flue 6 and the inner core 9 of being based on, and fan-shaped hydroecium 10 is a preferred version with 4～5, connects with gas baffle 25 at the edge of two fan-shaped hydroecium 10 close together up and down, forms the flue gas helical duct.

Be provided with removable end cap or cross screen 5 on the top of inner core 9.In the bottom of shell 4 sewage draining exit 17 is arranged, atmosphere entry 3 is arranged at the top, and the upper lateral part of inner core 9 has the steam whistle 30 through shell 4.

The utility model is described further in conjunction with the accompanying drawings:

Soft coal is added on the fixed grate 18 by dropping into for ort 19, the overheavy firing under arc radiation arch 22 and rear arch 14 effects of coal-fired layer, the high-temperature flue gas that is produced is under 21 disturbances of flue gas disturbance device, at exhanst gas outlet 12 places with after the secondary wind that secondary air mouth 13 enters mixes, rise around inner core 9 spirals, enter atmosphere through smoke pipe 2 and chimney 1.

During normal combustion, give ort 19 complete shut-downs, slag notch 16 is adjusted aperture according to combustion conditions, satisfies a wind intake.

2, referring to Fig. 1, when inner core 9 tops are provided with cross screen 5, backwater enters water space capacity in the shell 4 by water return outlet 15, water level is gone up the position in the middle of generally being controlled at water level meter 27 slightly, backwater rises when absorbing heat in boiler gradually, arrive upper boiler and flow into inner core 9 back continuation heat absorptions and drop to the bottom, flow out by the mouth of a river 11.

3, referring to Fig. 2, when inner core 9 tops were provided with end cap 5, backwater entered water space capacity in the shell 4 by water return outlet 15, and water level is gone up positions in the middle of generally being controlled at water level meter 27 slightly, backwater rises when absorbing heat in boiler gradually, arrives upper boiler and is flowed out by hot water outlet 28.

Running water is entered in the inner core 9 by the mouth of a river 11, and water level is gone up the position in the middle of generally being controlled at water level meter 29 slightly, and steam whistle 30 emitted vapour and sends sound when water was boiled, is flowed out for the people by drinking water outlet 31 and drinks.

The utility model has the following advantages compared to existing technology:

1, flue gas rises at the stove inside spin, has prolonged flue gas flow, is conducive to the after-flame of carbon black and has reduced the boiler export exhaust gas temperature.

Produce centrifugal force when 2, the flue gas spiral rises, realize dedusting in stove.

3, be provided with the flue gas disturbance device in the burner hearth, make flue gas generation disturbance in the burner hearth, help abundant burning.

4, backwater introduce to be risen by boiler bottom, drops to the boiler bottom through inner core and draws, and has prolonged the flow process that is heated water, helps heat absorption, improves boiler thermal output, simultaneously, be heated water in the boiler bottom high cigarette warm area draw, guaranteed the boiler hot-water outlet temperature.[referring to Fig. 1]

Can produce drinking water again when 5, producing hot water, realize a stove multipotency [referring to Fig. 2].
