Description

The multi-functional unpressurized hot water boiler of novel fuel

The utility model relates to a kind of fuel oil unpressurized hot water boiler.

Since the nineties, China unpressurized hot water boiler development is very fast, with coal, oil, gas is that unpressurized hot water boiler's product of fuel obtains exploitation in succession, and the production technology that applies to every profession and trade is widely used hot with heat and life, oil burning boiler particularly, because of its good environmental protection, operational management is convenient, production technology is simple, and low cost of manufacture has obtained very big development.But the fuel oil unpressurized hot water boiler of present exploitation, its heat exchange element merely uses bright and clean smoke pipe (or threaded flue), and volume is huge relatively, and the function of use of boiler is single, and 95 ℃ of heating hot waters (or health hot water of 65 ℃) can only be provided separately.

The purpose of this utility model is to provide a kind of boiler structure volume little, and thermal efficiency height can provide heating hot water below 95 ℃, the multifunctional fuel oil unpressurized hot water boiler of health hot water below 60 ℃ individually or simultaneously.

In order to achieve the above object, technical solution of the present utility model is: in boiler body, the Combustion chamber design that links to each other with flue becomes the waist word abnormally-structured; The convector of band high-efficiency helical finned tube is set in combustion chamber and front smoke box; Two independently water-water heat exchangers are set on boiler body top.Divide one the road to supply water in the water system of boiler through two water-water heat exchangers, in water-water heat exchanger with sanitary hot water system generation heat exchanging process after, supplying water with another road is mixed into the hot user of system.Sanitary hot water system carries out entering the hot water user of system after heat exchange heats up at water-hydro-thermal phallus.Realized that like this boiler has two and overlaps independently water system, wherein a cover is for heating water below 95 ℃ or 60 ℃ of air conditioning hots, another set ofly provides health hot water below 65 ℃, makes boiler have multiple function.A control water tank is set on system's return pipe, the valve of control water tank and boiler feedwater end interacts, system pressure in the separating to water end (W.E.) of boiler body, more than the high 100mm of peak level of control water tank minimum liquid level than boiler body, is guaranteed that boiler body is not with to press operation.

In the utility model structure, owing to be provided with the backhaul of the convector of band high-efficiency fin pipe as the smoke convection heat exchange in boiler body, the combustion chamber adopts the waist word abnormally-structured, has improved the thermal efficiency of boiler like this, has reduced the volume of boiler.Simultaneously two independently water-water heat exchangers are set on boiler body, cooperate corresponding water system.Make boiler that 95 ℃ of heating hot waters or 60 ℃ of air conditioning hots and the health hot water below 65 ℃ can be provided simultaneously.Realized the multi-functional of boiler.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model fuel oil multifunctional unpressurized hot water boiler longitudinal sectional view; Fig. 2 is the utility model fuel oil multifunctional unpressurized hot water boiler transverse sectional view; Fig. 3 is that the utility model is for providing the water system loop back path schematic diagram of multinomial function.

Fig. 1, the multi-functional unpressurized hot water boiler of novel fuel of the present utility model shown in Figure 2 are horizontal internal combustion three return structures.Mainly include parts such as boiler body 15, base 2, water-water heat exchanger 12, front smoke box 13, back smoke box 9, heat-insulation layer 14, covering 17, exhanst gas outlet 8, combustor 1.Boiler body 15 is made up of flue 3, combustion chamber 4, explosion proof door 5, the convector 10 of being with the high-efficiency helical finned tube, threaded flue 11 etc.The convector 10 of high-efficiency helical finned tube is set between combustion chamber 4 and the front smoke box 13.Two independently water-water heat exchangers 12 are set on boiler body 15.Oil is in 1 li igniting automatically of combustor.In first backhaul of flue 3 and combustion chamber 4 compositions, burn.High-temperature flue gas in the combustion chamber 4 through second backhaul the convector 10 of the efficient screw finned pipe of band enter into front smoke box 13.The flue gas of front smoke box 13 is by the threaded flue 11 of the 3rd backhaul.Enter into back smoke box 9.Finish the heat transfer process of flue gas and medium, be drained into the atmospheric environment from exhanst gas outlet 8 then.

Shown in Figure 3 is that the utility model is for providing the water system closed circuit schematic diagram of multinomial function.It includes boiler body 15.Water-water heat exchanger 12, water circulating pump 18, hot user 19, health hot water user 20, parts such as control water tank 24 and valve.Control water tank 24 is provided with separately, links to each other with boiler body 15 by taking over, and control water tank 24 includes internally piloted valve 21, float-controlled valve 22, overflow pipe 25, air pipe 23.System's backwater links to each other with internally piloted valve 21 by valve, and internally piloted valve 21 and float-controlled valve 22 synergy are with the system pressure pressure release and realize flow equilibrium, on control water tank 24 air pipe 23 is installed simultaneously, guarantees that boiler body does not have the operation of pressure.95 ℃ of heating hot waters are carried by dividing two tunnel operations behind the valve B by water circulating pump 18 through system water supply pipe 16 and valve A in the boiler body, wherein one the tunnel enter water-water heat exchanger 12 through valve D, after the heat exchange, be mixed into hot user 19 through valve E with another road hot water by valve C, the system requirements of heating hot water below 95 ℃ or 60 ℃ of air conditioning hots can be provided like this, running water enters water-water heat exchanger 12 through valve F and produces health hot water below 65 ℃ and enter health hot water user 20, realizes providing the health hot water function.
