Description

Circulating multitube heat absorption civil boiler

Technical field

The utility model is a kind of circulation ability of swimming, a multitube heat absorption heating boiler, be a kind ofly adopt thermal efficiency height, heating load is big, the water circulation power is big, fuel saving, rationally utilize the civilian arcola of heat.

Background technology

Present existing civil boiler has bell, double wall stove hall, fire grate, fire door, furnace bottom, double wall stove tube, outlet pipe and return pipe.Because the stove tube is a monotubular, its heating surface area is little, and it is low to adopt the thermal efficiency, does not have return pipe on the stove tube, makes the water of stove tube hydroecium be heated and can not circulate from outlet pipe to stove tube end, has lost the effect of heat supply.Because of the hot heating efficiency of adopting of boiler is low, most of heat enters the flue of a kang, makes heated kang too hot, can not sleep, can not sit, and irons and sticks with paste clothing, a heatable brick bed leather, it's a pity that more heat runs off from chimney by the flue of a kang, has wasted fuel.

Summary of the invention

At the technical deficiency and the defective of existing boiler, the utility model provides a kind of boiler, and this boiler is adopted thermal efficiency height, the water circulation power is big, heating load big, fuel saving, avoid heat to run off, rationally utilize the boiler of heat.

The purpose of this utility model is achieved through the following technical solutions.

Circular double wall stove hall, on its outer wall to bell, down to furnace bottom, on the inwall to bell, down to fire grate, all weld up and down with stove hall outer wall, gap 4-5 millimeter between two walls forms stove hall hydroecium, and the return pipe of stove hall is welded on the bottom of stove hall hydroecium, be the minimum position of stove hall hydroecium temperature, help the water circulation of stove hall.

The main improved technical scheme of the utility model is the stove tube, and for being fit to the structure of boiler, the outer wall of double wall stove tube is the rectangle tube, and inwall is the rectangle that is composed in parallel by many square tubes.Its composing method is that the two ends of square tube are stretched in two screen bed bases respectively and welding.Gap 3-4 millimeter between screen bed base between square tube, square tube does not have an end of frame screen bed base, the rectangular tube of one section 7-9 centimeter length of welding, the diameter of rectangular tube is identical with the rectangle that square tube is formed.The other end of rectangular tube stretches into the stove hall, welds with stove hall inwall.The other end of square tube is contacted and welds with furnace tube outer wall by the frame of screen bed base.The other end of furnace tube outer wall and the welding of stove hall outer wall make stove tube hydroecium be communicated with stove hall hydroecium.

Described stove tube hydroecium is the stove tube hydroecium that the gap of gap between the square tube and square tube and furnace tube outer wall forms.The return pipe of stove tube be arranged on contiguous stove tube end below, be the minimum position of stove tube hydroecium temperature, help the water circulation of stove tube hydroecium, increased the water circulation power.

The outlet pipe of boiler is arranged on the stove tube above the square tube of contiguous rectangular tube and square tube weld, and the position of outlet pipe is that Lu Tangshui and stove tube water pool together the highest position of temperature, helps hot water come-up generation water circulation power.

The water circulation power of boiler is the different water circulation powers that produce of proportion of being facilitated water by the temperature difference of water.

The stove tube inwall of forming by many square tubes, make the endotherm area of stove tube inwall increase more than 3 times, the pyrotechnics heat is by the square tube internal diameter, heat is fully absorbed, improved the thermal efficiency of adopting of boiler, stove tube end is provided with return pipe, and the condition of water circulation is provided for the stove tube, improve the defective of original boiler, increased the water circulation power of boiler.

Use to confirm that through reality the beneficial effects of the utility model are, under the identical situation of fuel, heating load increases more than 2 times, and the phenomenon that heated kang is too warm thoroughly disappears.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further specified

Fig. 1 is overall structure figure of the present utility model

Fig. 2 is screen bed base and instrument: mediation shovel figure

In the accompanying drawings, the rectangular tube of bell (1), stove hall outer wall (2), stove hall inwall (3), fire grate (4), fire door (5), furnace bottom (6), stove hall return pipe (7), stove tube inwall (8), outlet pipe (9), furnace tube outer wall (10), many square tubes of stove tube inwall (11), stove tube return pipe (12), backwater tube connector (13), four-way (14), frame screen bed base (15), no frame screen bed base (16), instrument are arranged: (17) are shoveled in mediation

The specific embodiment

In the accompanying drawings, be that round kiln hall outer wall (2) is connected with furnace bottom (6) below the bell (1), stove hall inwall (3) is gone up to bell (1), all welds the gap 4-5 millimeter between two walls, formation stove hall hydroecium up and down with stove hall outer wall (2) down to fire grate (4).The return pipe of stove hall (7) is welded on the bottom of stove hall hydroecium, belongs to the low temperature position of stove hall hydroecium.Fire grate (4) is a double wall stove hall at stove hall middle part above, and following is ash chamber.

Double wall furnace tube outer wall (10) is rectangular tube, and its inwall is made up of many square tubes (11) and rectangular tube (8).Composing method is: an end of many square tubes (11), stretched in the frame screen bed base (15) and welding, the frame of screen bed base contacts and welds with the internal diameter of furnace tube outer wall (10), between the frame of screen bed base across the gap 3-4 millimeter of square tube (11) and furnace tube outer wall (10), the other end of many square tubes (11) stretches in the no frame screen bed base (16) and welding, the gap 3-4 millimeter between screen bed base between square tube.Square tube does not have an end rectangular tube of welding (8) of frame screen bed base (16), and the other end of rectangular tube (8) stretches into Lu Tang and stove hall inwall (3) welding, and an end of furnace tube outer wall (10) and stove hall outer wall (2) welding make stove tube hydroecium be communicated with stove hall hydroecium.Described stove tube hydroecium is gap between the square tube and the gap between square tube and the furnace tube outer wall (10), the stove tube hydroecium of formation.
