Abstract
Disclosed is a direct-burn non-pressure hot water unit for central air-conditioning or heating system, which comprises a burner, a combustion chamber, a sprinkler, a heating channel, a water storage tank and an exhaust pipe. The utility model uses the burner to spray the fuel oil or fuel gas to the combustion chamber and generates high temperature flame after sufficient combustion. The high temperature flame contact with the water directly. The water absorbs the heat of the high temperature flame to make the water temperature increase. Compared with the fire tube type indirect heating hot water unit or boiler, the utility model is high in heat transfer efficiency, small in volume.
Description
The utility model relates to a kind of fire directly and the non-pressure hot water unit of water transmission of heat by contact, is mainly used in central air-conditioning or the hot water system.
At present, the hot water unit on the market all is modifieds of hot-water boiler, and its structure is identical with principle.Hot-water boiler adopts the waterpipe type structure, and the thermal-flame that fuel combustion produces is passed to water at low temperature by heat-transfer pipe with heat, and the temperature of water is improved.In the process of heat by tube wall transmission feedwater, the influence that its heat transfer coefficient is subjected to pipe wall material, pipe thickness, cigarette ash and incrustation scale thickness is very big.Therefore the factor of boiler consideration when design is a lot, and consequently boiler volume is huge, thermal losses is big, efficient is low, cost is high.
The purpose of this utility model provides a kind of, the non-pressure hot water unit of fire and water direct contact heat transfer.
The purpose of this utility model is achieved in that fuel oil or combustion gas by burner, does fully to burn in the combustion chamber of hot water unit.The thermal-flame that the burning back produces is admitted to heat tunnel, and water is made the spray shape by the top of heat tunnel and sprayed downwards, and thermal-flame is passed to water with heat in heat tunnel.Waste gas is discharged the hot water unit by the smoke exhaust pipe of upper boiler.Heated water concentrates in the water storage tank of hot water unit, is extracted out by pump and sends in central air-conditioning or the heating system.
Owing to adopted such scheme, the heat transfer coefficient of hot water unit increases, volume reduces, efficient improves.
Below in conjunction with drawings and Examples utility model is further specified.
Accompanying drawing is a sectional structural map of the present utility model.
1. burners, 2. heat tunnels, 3. spray throwers, 4. smoke exhaust pipes, 5. water supply interlayers, 6. packing layers, 7. water inlet ball-cock assemblys, 8. water storage tanks, 9. outlet pipes, 10. combustion chambers, 11. refractory materials among the figure
In the drawings, burner 1 sprays into ignition in the combustion chamber 10 with fuel oil or combustion gas.The combustion chamber is made by refractory material 11, and purpose is to improve temperature, and fuel is done fully burning, forms thermal-flame.Combustion chamber 10 is located at a side of hot water unit, and opposite side is a water storage tank 8, and the outlet of combustion chamber 10 is lower than the water surface of water storage tank, and purpose is the height that reduces the hot water unit.Thermal-flame is by the outlet of combustion chamber, through the space between combustion chamber 10 and the water storage tank 8, upwards enter heat tunnel 2 after, thermal-flame is done up and down in heat tunnel and is moved to the smoke exhaust pipe direction.The spray thrower 3 at heat tunnel top sprays water at low temperature downwards, finishes diabatic process fiery and water with thermal-flame in heat tunnel.For increasing the time of contact of water and thermal-flame, in heat tunnel, be provided with packing layer 6, filler adopts hollow magnetic tube, and water stops at packing layer in the spray process.After the heat of thermal-flame was taken away by water, high-temperature water entered in the water storage tank 8 of heat tunnel 2 bottoms.When outlet pipe 9 outwards supplied water, the water level of water storage tank 8 descended, and water inlet ball-cock assembly 7 is opened under the effect of ball float, and the water that enters ball-cock assembly flows into spray thrower 3 along water supply interlayer 5, and the water yield that how much is subjected to of inflow is controlled.The waste gas of hot water unit is by the smoke exhaust pipe 4 behind the heat tunnel, discharges and communicates with atmosphere.Therefore, in the hot water unit course of work, hot water unit inside is not have to press.
Claims (4)
1, a kind of direct-fired non-pressure hot water unit, it mainly is made up of burner, heat tunnel, spray thrower, packing layer, water inlet ball-cock assembly, water storage tank, combustion chamber, outlet pipe, it is characterized in that: combustion chamber and water storage tank are respectively in the both sides of hot water unit, the centre is left the space and is linked to each other with the heat tunnel import, and the top of water storage tank is heat tunnel.
2, according to claim 1, direct-fired non-pressure hot water unit is characterized in that: spray thrower is at the top of heat tunnel.
3, according to claim 1, direct-fired non-pressure hot water unit, it is waited to levy and is: be provided with packing layer in heat tunnel.
4, according to claim 1, direct-fired non-pressure hot water unit, it is waited to levy and is: smoke exhaust pipe is located at the rear portion of heat tunnel.
